Fundamentals of Nursing NCLEX RN Practice Questions Q&A 2
1. 1. Question
Which intervention is an example of primary prevention?
o A. Administering
... [Show More] digoxin (Lanoxicaps) to a patient with heart failure.
o B. Administering measles, mumps, and rubella immunization to an infant.
o C. Obtaining a Papanicolaou smear to screen for cervical cancer.
o D. Using occupational therapy to help a patient cope with arthritis.
Incorrect
Correct Answer: B. Administering measles, mumps, and rubella immunization to an infant.
Immunizing an infant is an example of primary prevention, which aims to prevent health problems. Primary prevention includes those preventive measures that come before the onset of illness or injury and before the disease process begins. Examples include immunization and taking regular exercise to prevent health problems developing in the future.
o Option A: Administering digoxin to treat heart failure and obtaining a smear for a screening test are examples for secondary prevention, which promotes early detection and treatment of disease. Those preventive measures that lead to early diagnosis and prompt treatment of a disease, illness, or injury to prevent more severe problems developing. Here health educators such as Health Extension Practitioners can help individuals acquire the skills of detecting diseases in their early stages.
o Option C: Obtaining a Papanicolau smear is a secondary prevention. Secondary prevention includes those preventive measures that lead to early diagnosis and prompt treatment of a disease, illness, or injury. This should limit disability, impairment, or dependency and prevent more severe health problems developing in the future.
o Option D: Using occupational therapy to help a patient cope with arthritis is an example of tertiary prevention, which aims to help a patient deal with the residual consequences of a problem or to prevent the problem from recurring. Tertiary prevention includes those preventive measures aimed at rehabilitation following significant illness. At this level, health educators work to retrain, re-educate and rehabilitate the individual who has already had an impairment or disability.
2. 2. Question
The nurse in charge is assessing a patient’s abdomen. Which examination technique should the nurse use first?
o A. Auscultation
o B. Inspection
o C. Percussion
o D. Palpation
Incorrect
Correct Answer: B. Inspection
Inspection always comes first when performing a physical examination. It is important to begin with the general examination of the abdomen with the patient in a completely supine position. The presence of any of the following signs may indicate specific disorders. Percussion and palpation of the abdomen may affect bowel motility and therefore should follow auscultation.
o Option A: The last step of the abdominal examination is auscultation with a stethoscope. The diaphragm of the stethoscope should be placed on the right side of the umbilicus to listen to the bowel sounds, and their rate should be calculated after listening for at least two minutes. Normal bowel sounds are low-pitched and gurgling, and the rate is normally 2-5/min. Absent bowel sounds may indicate paralytic ileus and hyperactive rushes (borborygmi) are usually present in small bowel obstruction and sometimes may be auscultated in lactose intolerance.
o Option C: A proper technique of percussion is necessary to gain maximum information regarding the abdominal pathology. While percussing, it is important to appreciate tympany over air-filled structures such as the stomach and dullness to percussion which may be present due to an underlying mass or organomegaly (for example, hepatomegaly or splenomegaly).
o Option D: The ideal position for abdominal examination is to sit or kneel on the right side of the patient with the hand and forearm in the same horizontal plane as the patient’s abdomen. There are three stages of palpation that include the superficial or light palpation, deep palpation, and organ palpation and should be performed in the same order. Maneuvers specific to certain diseases are also a part of abdominal palpation.
3. 3. Question
Which statement regarding heart sounds is correct?
o A. S1 and S2 sound equally loud over the entire cardiac area.
o B. S1 and S2 sound fainter at the apex.
o C. S1 and S2 sound fainter at the base.
o D. S1 is loudest at the apex, and S2 is loudest at the base.
Incorrect
Correct Answer: D. S1 is loudest at the apex, and S2 is loudest at the base.
The S1 sound—the “lub” sound—is loudest at the apex of the heart. It sounds longer, lower, and louder there than the S2 sounds. The S2—the “dub” sound—is loudest at the base. It sounds shorter, sharper, higher, and louder there than S1. Heart sounds are created from blood flowing through the heart chambers as the cardiac valves open and close during the cardiac cycle. Vibrations of these structures from the blood flow create audible sounds — the more turbulent the blood flow, the more vibrations that get created.
o Option A: The S1 heart sound is produced as the mitral and tricuspid valves close in systole. This structural and hemodynamic change creates vibrations that are audible at the chest wall. The mitral valve closing is the louder component of S1. It also occurs sooner because of the left ventricle contracts earlier in systole.
o Option B: Changes in the intensity of S1 are more attributable to forces acting on the mitral valve. Such causes include a change in left ventricular contractility, mitral structure, or the PR interval. However, under normal resting conditions, the mitral and tricuspid sounds occur close enough together not to be discernible. The most common reasons for a split S1 are things that delay right ventricular contraction, like a right bundle branch block.
o Option C: The S2 heart sound is produced with the closing of the aortic and pulmonic valves in diastole. The aortic valve closes sooner than the pulmonic valve, and it is the louder component of S2; this occurs because the pressures in the aorta are higher than the pulmonary artery.
4. 4. Question
The nurse in charge identifies a patient’s responses to actual or potential health problems during which step of the nursing process?
o A. Assessment
o B. Nursing diagnosis
o C. Planning
o D. Evaluation
Incorrect
Correct Answer: B. Nursing diagnosis
The nurse identifies human responses to actual or potential health problems during the nursing diagnosis step of the nursing process. The formulation of a nursing diagnosis by employing clinical judgment assists in the planning and implementation of patient care. The North American Nursing Diagnosis Association (NANDA) provides nurses with an up to date list of nursing diagnoses. A nursing diagnosis, according to NANDA, is defined as a clinical judgment about responses to actual or potential health problems on the part of the patient, family or community.
o Option A: During the assessment step, the nurse systematically collects data about the patient or family. Assessment is the first step and involves critical thinking skills and data collection; subjective and objective. Subjective data involves verbal statements from the patient or caregiver. Objective data is measurable, tangible data such as vital signs, intake and output, and height and weight.
o Option C: During the planning step, the nurse develops strategies to resolve or decrease the patient’s problem. The planning stage is where goals and outcomes are formulated that directly impact patient care based on EDP guidelines. These patient-specific goals and the attainment of such assist in ensuring a positive outcome.
o Option D: During the evaluation step, the nurse determines the effectiveness of the plan of care. This final step of the nursing process is vital to a positive patient outcome. Whenever a healthcare provider intervenes or implements care, they must reassess or evaluate to ensure the desired outcome has been met. Reassessment may frequently be needed depending upon overall patient condition. The plan of care may be adapted based on new assessment data.
5. 5. Question
A female patient is receiving furosemide (Lasix), 40 mg P.O. b.i.D. in the plan of care, the nurse should emphasize teaching the patient about the importance of consuming:
o A. Fresh, green vegetables
o B. Bananas and oranges
o C. Lean red meat
o D. Creamed corn
Incorrect
Correct Answer: B. Bananas and oranges
Because furosemide is a potassium-wasting diuretic, the nurse should plan to teach the patient to increase intake of potassium-rich foods, such as bananas and oranges. Potassium is a mineral in the cells. It helps the nerves and muscles work as they should. The right balance of potassium also keeps the heart beating at a steady rate. Fresh, green vegetables; lean red meat; and creamed corn are not good sources of potassium.
o Option A: GLVs are considered as natural caches of nutrients for human beings as they are a rich source of vitamins, such as ascorbic acid, folic acid, tocopherols, ?-carotene, and riboflavin, as well as minerals such as iron, calcium, and phosphorous.
o Option C: Lean red meat is an excellent source of high biological value protein, vitamin B12, niacin, vitamin B6, iron, zinc, and phosphorus. It is a source of long?chain omega?3 polyunsaturated fats, riboflavin, pantothenic acid, selenium, and, possibly, also vitamin D. It is also relatively low in fat and sodium.
o Option D: Corn has several health benefits. Because of the high fiber content, it can aid with digestion. It also contains valuable B vitamins, which are important to your overall health. Corn also provides our bodies with essential minerals such as zinc, magnesium, copper, iron, and manganese.
6. 6. Question
The nurse in charge must monitor a patient receiving chloramphenicol for adverse drug reaction. What is the most toxic reaction to chloramphenicol?
o A. Lethal arrhythmias
o B. Malignant hypertension
o C. Status epilepticus
o D. Bone marrow suppression
Incorrect
Correct Answer: D. Bone marrow suppression
The most toxic reaction to chloramphenicol is bone marrow suppression. Chloramphenicol is a synthetically manufactured broad-spectrum antibiotic. It was initially isolated from the bacteria Streptomyces venezuelae in 1948 and was the first bulk produced synthetic antibiotic. However, chloramphenicol is a rarely used drug in the United States because of its known severe adverse effects, such as bone marrow toxicity and grey baby syndrome. Chloramphenicol is not known to cause lethal arrhythmias, malignant hypertension, or status epilepticus.
o Option A: Chloramphenicol is associated with severe hematological side effects when administered systemically. Since 1982, chloramphenicol has reportedly caused fatal aplastic anemia, with possible increased risk when taken together with cimetidine. This adverse side effect can occur even with the topical administration of the drug, which is most likely due to the systemic absorption of the drug after topical application.
o Option B: Besides causing fatal aplastic anemia and bone marrow suppression, other side effects of chloramphenicol include ototoxicity with the use of topical ear drops, gastrointestinal reactions such as oesophagitis with oral use, neurotoxicity, and severe metabolic acidosis.
o Option C: Optic neuritis is the most commonly associated neurotoxic complication that can arise from chloramphenicol use. This adverse effect usually takes more than six weeks to manifest, presenting with either acute or subacute vision loss, with possible fundal changes. It may also present with peripheral neuropathy, which may present as numbness or tingling. If optic neuropathy occurs, the drug should be withdrawn immediately, which will usually lead to partial or complete recovery of vision.
7. 7. Question
A female patient is diagnosed with deep-vein thrombosis. Which nursing diagnosis should receive highest priority at this time?
o A. Impaired gas exchanges related to increased blood flow.
o B. Fluid volume excess related to peripheral vascular disease.
o C. Risk for injury related to edema.
o D. Altered peripheral tissue perfusion related to venous congestion.
Incorrect
Correct Answer: D. Altered peripheral tissue perfusion related to venous congestion.
Altered peripheral tissue perfusion related to venous congestion” takes highest priority because venous inflammation and clot formation impede blood flow in a patient with deep-vein thrombosis. A deep-vein thrombosis (DVT) is a blood clot that forms within the deep veins, usually of the leg, but can occur in the veins of the arms and the mesenteric and cerebral veins. Deep-vein thrombosis is a common and important disease. It is part of the venous thromboembolism disorders which represent the third most common cause of death from cardiovascular disease after heart attacks and stroke.
o Option A: Option A is incorrect because impaired gas exchange is related to decreased, not increased, blood flow. Depending on the relative balance between the coagulation and thrombolytic pathways, thrombus propagation occurs. DVT is commonest in the lower limb below the knee and starts at low-flow sites, such as the soleal sinuses, behind venous valve pockets.
o Option B: Option B is inappropriate because no evidence suggests that this patient has a fluid volume excess. Nurses need to educate the patients on the importance of ambulation, being compliant with compression stockings, and taking the prescribed anticoagulation medications.
o Option C: Option C may be warranted but is secondary to altered tissue perfusion. Thrombosis is a protective mechanism that prevents the loss of blood and seals off damaged blood vessels. Fibrinolysis counteracts or stabilizes the thrombosis. The triggers of venous thrombosis are frequently multifactorial, with the different parts of the triad of Virchow contributing in varying degrees in each patient, but all result in early thrombus interaction with the endothelium. This then stimulates local cytokine production and causes leukocyte adhesion to the endothelium, both of which promote venous thrombosis.
8. 8. Question
When positioned properly, the tip of a central venous catheter should lie in the:
o A. Superior vena cava
o B. Basilica vein
o C. Jugular vein
o D. Subclavian vein
Incorrect
Correct Answer: A. Superior vena cava
When the central venous catheter is positioned correctly, its tip lies in the superior vena cava, inferior vena cava, or the right atrium—that is, in central venous circulation. Blood flows unimpeded around the tip, allowing the rapid infusion of large amounts of fluid directly into circulation. The basilica, jugular, and subclavian veins are common insertion sites for central venous catheters.
o Option B: There are three main access sites for the placement of central venous catheters. The internal jugular vein, common femoral vein, and subclavian veins are the preferred sites for temporary central venous catheter placement. Additionally, for mid-term and long-term central venous access, the basilic and brachial veins are utilized for peripherally inserted central catheters (PICCs).
o Option C: The internal jugular vein (IJ) is often chosen for its reliable anatomy, accessibility, low complication rates, and the ability to employ ultrasound guidance during the procedure. The individual clinical scenario may dictate laterality in some cases (such as with trauma, head and neck cancer, or the presence of other invasive devices or catheters), but all things being equal, many physicians prefer the right IJ. As compared to the left, the right IJ forms a more direct path to the superior vena cava (SVC) and right atrium. It is also wider in diameter and more superficial, thus presumably easier to cannulated.
o Option D: The subclavian vein site has the advantage of low rates of both infectious and thrombotic complications. Additionally, the SC site is accessible in trauma, when a cervical collar negates the choice of the IJ. However, disadvantages include a higher relative risk of pneumothorax, less accessibility to use ultrasound for CVC placement, and the non-compressible location posterior to the clavicle.
9. 9. Question
Nurse Nikki is revising a client’s care plan. During which step of the nursing process does such revision take place?
o A. Assessment
o B. Planning
o C. Implementation
o D. Evaluation
Incorrect
Correct Answer: D. Evaluation
During the evaluation step of the nursing process, the nurse determines whether the goals established in the care plan have been achieved, and evaluates the success of the plan. If a goal is unmet or partially met the nurse reexamines the data and revises the plan. This final step of the nursing process is vital to a positive patient outcome. Whenever a healthcare provider intervenes or implements care, they must reassess or evaluate to ensure the desired outcome has been met. Reassessment may frequently be needed depending upon overall patient condition. The plan of care may be adapted based on new assessment data. Assessment involves data collection. Planning involves setting priorities, establishing goals, and selecting appropriate interventions.
o Option A: Assessment is the first step and involves critical thinking skills and data collection; subjective and objective. Subjective data involves verbal statements from the patient or caregiver. Objective data is measurable, tangible data such as vital signs, intake and output, and height and weight.
o Option B: The planning stage is where goals and outcomes are formulated that directly impact patient care based on EDP guidelines. These patient-specific goals and the attainment of such assist in ensuring a positive outcome. Nursing care plans are essential in this phase of goal setting. Care plans provide a course of direction for personalized care tailored to an individual’s unique needs. Overall condition and comorbid conditions play a role in the construction of a care plan. Care plans enhance communication, documentation, reimbursement, and continuity of care across the healthcare continuum.
o Option C: Implementation is the step that involves action or doing and the actual carrying out of nursing interventions outlined in the plan of care. This phase requires nursing interventions such as applying a cardiac monitor or oxygen, direct or indirect care, medication administration, standard treatment protocols, and EDP standards.
10. 10. Question
A 65-year-old female who has diabetes mellitus and has sustained a large laceration on her left wrist asks the nurse, “How long will it take for my scars to disappear?” Which statement would be the nurse’s best response?
o A. “The contraction phase of wound healing can take 2 to 3 years.”
o B. “Wound healing is very individual but within 4 months the scar should fade.
o C. “With your history and the type of location of the injury, it’s hard to say.”
o D. “If you don’t develop an infection, the wound should heal any time between 1 and 3 years from now.”
Incorrect
Correct Answer: C. “With your history and the type of location of the injury, it’s hard to say.”
Wound healing in a client with diabetes will be delayed. Providing the client with a time frame could give the client false information. There is no doubt that diabetes plays a detrimental role in wound healing. It does so by affecting the wound healing process at multiple steps. Wound hypoxia, through a combination of impaired angiogenesis, inadequate tissue perfusion, and pressure-related ischemia, is a major driver of chronic diabetic wounds.
o Option A: Ischemia can lead to prolonged inflammation, which increases the levels of oxygen radicals, leading to further tissue injury. Elevated levels of matrix metalloproteases in chronic diabetic wounds, sometimes up to 50-100 times higher than acute wounds, cause tissue destruction and prevent normal repair processes from taking place. Furthermore, diabetes is associated with impaired immunity, with critical defects occurring at multiple points within the immune system cascade of the wound healing process.
o Option B: To further complicate matters, these wounds have defects in angiogenesis and neovascularization. Normally, wound hypoxia stimulates mobilization of endothelial progenitor cells via vascular endothelial growth factor (VEGF). In diabetic wounds, there are aberrant levels of VEGF and other angiogenic factors such as angiopoietin-1 and angiopoietin-2 that lead to dysangiogenesis.
o Option D: Diabetic neuropathy may also play a role in poor wound healing. Lower levels of neuropeptides, as well as reduced leukocyte infiltration as a result of sensory denervation, have been shown to impair wound healing. When combined, all these diverse factors play a role in the formation and propagation of chronic, debilitating wounds in patients with diabetes. [Show Less]
