A nurse is monitoring a client who is taking spironolactone for the treatment of hypertension. Which findings denote adverse effects of the medication? Sel... [Show More] ect all that apply.
Tall T waves
Prolonged PR interval
Hyperactive bowel sounds
Rationale: Spironolactone is a potassium-sparing diuretic. Potassium-sparing diuretics can cause hyperkalemia. Cardiovascular manifestations of hyperkalemia include tall T waves, widened QRS complexes, prolonged PR intervals, and flat P waves. Other cardiovascular manifestations include an irregular heart rate, decreased blood pressure, and ectopic heartbeats. Muscle twitches occur in hyperkalemia. Hyperactive bowel sounds and diarrhea also occur in hyperkalemia. Constipation, hyporeflexia, and shallow respirations are signs of hypokalemia.
A nurse is providing dietary instructions to a client with chronic obstructive pulmonary disease (COPD) who is experiencing a loss of appetite and complains of feeling "too full to eat." What does the nurse encourage the client to do? Select all that apply.
Avoid drinking fluids before and during meals
Select foods that are easy to chew and are not gas forming
Rationale: COPD is a progressive and irreversible condition characterized by diminished inspiratory and expiratory capacity of the lungs. Instruct the client who complains of feeling too full to eat, to avoid drinking fluids before and during the meal. Dry foods such as crackers stimulate coughing; foods such as milk and chocolate may increase the thickness of saliva and secretions. Cheese is constipating and should also be avoided by the client. The nurse should also teach the client about foods that are easy to chew and do not encourage the formation of gas; for this reason, broccoli, which is a gas-forming food, should be avoided.
A tuberculin skin test (TST) is administered to a client with a diagnosis of HIV infection. Forty-eight hours after administration, the nurse checks the test site (see image).
Positive
Rationale: The tuberculin, or TST, test is a reliable determinant of tuberculosis (TB) infection. A reaction measuring 5 mm or more in diameter is considered positive in a client with HIV infection. A reaction measuring 10 mm or more in diameter is considered positive in a non-immunosuppressed client. In this instance, the area of induration measures 9 mm, indicating a positive reaction. A positive reaction does not mean that active disease is present, but it does indicate exposure to TB or the presence of inactive (dormant) disease.
A nurse is interpreting a central venous pressure (CVP) reading from a client in whom right ventricular failure has been diagnosed. From this diagnosis, the nurse would expect that the most likely result is a pressure of
14 cm H2O
Rationale: CVP measurements are used to monitor blood volume and the adequacy of venous return to the heart. The CVP measures pressures from the right atrium or central veins. The normal CVP is 7 to 12 cm H2O. An increased CVP reading may indicate right ventricular failure. A low CVP reading may indicate hypovolemia. A reading of 4 cm H2O is low. Readings of 8 and 11 cm H2O are normal. A reading of 14 cm H2O is increased.
A nurse is caring for a client who has just undergone thyroidectomy. Which technique is the best way for the nurse to assess the surgical site for bleeding?
Checking for moisture on the back of the dressing over the client's neck and shoulders
Rationale: Thyroid surgery may be complicated by hemorrhage, respiratory distress, parathyroid gland injury (resulting in hypocalcemia and tetany), damage to the laryngeal nerves, and thyroid storm. Hemorrhage is most likely during the 24 hours after surgery. If the client is bleeding after surgery, gravity will cause the blood to seep down the sides of the dressing and drain onto the underlying bed linens even as the top of the dressing remains clean and dry. Asking the client whether the dressing feels wet and replacing the dry sterile dressing every 2 hours are not the best actions. Replacing the dressing frequently when it is not warranted could also increase the risk of infection.
A client who sustained a major burn injury is beginning to take an oral diet again. Which between-meal menu selections meet the client's needs for wound healing and tissue repair? Select all that apply.
Whole-milk shake and granola
Baked potato topped with cheese
Cheese and whole-wheat crackers
Rationale: To facilitate healing and meet continued high metabolic needs, the client with a major burn should eat a diet high in calories, protein, and carbohydrates. This type of diet also keeps the client in positive nitrogen balance. Foods such as milkshakes, granola, cheese, and whole-wheat products are acceptable choices. Though fresh fruits and vegetables and skim milk are high in nutrients, higher-calorie foods, including versions of dairy products prepared with whole milk, are preferable in this situation.
A client is found to have hypoparathyroidism. Which nutritional supplement does the nurse, teaching the client about measures to manage the disorder, tell the client to take on a daily basis?
Calcium carbonate with vitamin D
Rationale: Hypoparathyroidism is an endocrine disorder in which parathyroid function is decreased. The client with hypoparathyroidism is likely to have low calcium and high phosphate levels and should consume a diet high in calcium but low in phosphorus. Additionally, the generally used treatment is calcium supplementation (either as calcium carbonate or calcium citrate) coupled with vitamin D supplementation. Vitamin C supplementation is not a treatment measure for this disorder. Beta-carotene is incorrect, because a client with hypoparathyroidism typically has an increased phosphorus level
A nurse participating in a free health screening at the local mall obtains a random blood glucose level of 190 mg/dL (10.6 mmol/L) and a total cholesterol level of 210 mg/dL (5.4 mmol/L) in an otherwise healthy client. What should the nurse tell the client to do next?
Call his health care provider to have these values rechecked as soon as possible
Rationale: Adult diabetes mellitus may be diagnosed on the basis of symptoms (e.g., polydipsia, polyuria, polyphagia) or laboratory values. An abnormal glucose tolerance test, a random plasma glucose level greater than 200 mg/dL (11.1 mmol/L), and a fasting plasma glucose level greater than 140 mg/dL (7.8 mmol/L) on two separate occasions are all diagnostic of diabetes mellitus. The total cholesterol should be less than 200 mg/dL (5.2 mmol/L). Confirmation of this client's results is needed to ensure appropriate diagnosis and therapy.
Levothyroxine sodium is prescribed for a client with hypothyroidism, and the nurse provides information to the client about the medication. Which occurrences does the nurse tell the client to report to the health care provider? Select all that apply.
Chest pain
Palpitations
Rapid heart rate
Rationale: The client taking levothyroxine sodium may have manifestations of hypothyroidism if the dosage is inadequate or may experience manifestations of hyperthyroidism if the dosage is too high. Thyroid preparations increase metabolic rate, oxygen demands, and demands on the heart, which may result in angina and cardiac dysrhythmias. The client should be instructed to report chest pain, palpitations, or a rapid heart rate immediately. Lethargy, constipation, and weight gain are symptoms of hypothyroidism, which should improve with medication therapy (e.g., levothyroxine sodium).
A nurse is developing a plan of care for an older client with diabetic neuropathy of the lower extremities resulting from type 2 diabetes mellitus. Which problem does the nurse recognize as the highest priority for this client?
Increased risk for injury
Rationale: The client with diabetic neuropathy of the lower extremities has a diminished sensation in the legs and feet. This client is at risk for tissue injury and for falls as a result of this nervous system impairment. Therefore the highest priority nursing problem is increased risk for injury. Increased risk of depression and change in body image are more psychosocial in nature and, as such, are secondary needs. A lower level of physical activity may be a problem but is not the priority.
The nurse is teaching a client with newly diagnosed diabetes mellitus who has been prescribed NPH insulin how to recognize the signs of hypoglycemia. The client states that he must look for certain signs and symptoms in the late afternoon, indicating to the nurse that he has understood the instructions. What are these signs and symptoms? Select all that apply.
Shakiness
Blurred vision
Feelings of hunger
Rationale: The client taking NPH insulin experiences peak medication effects 6 to 12 hours after administration. When the medication's action peaks, the client is at risk of hypoglycemia if food intake is insufficient. The nurse teaches the client to be alert for signs and symptoms of hypoglycemia, including anxiety, confusion, difficulty concentrating, blurred vision, cold sweats, headache, increased pulse, shakiness, and hunger. The other options are signs and symptoms of hyperglycemia
Glargine insulin is prescribed for a client with type 1 diabetes mellitus. What does the nurse tell the client about this type of insulin? Select all that apply
It does not have a peak effect.
It is usually given once daily, at bedtime.
It usually has a 24-hour duration of action
Rationale: Glargine insulin, a long-acting basal insulin analog, has an onset of action of 1 to 2 hours, with no peak effect, and a duration of action of more than 24 hours. It is usually given once daily, preferably at bedtime. Glargine insulin may not be mixed in a syringe with other insulin.
A client arrives in the emergency department after sustaining a chemical splash to the eye. The nurse immediately flushes the eye with copious amounts of normal saline solution for 15 minutes and then tests the pH of eye, using litmus paper. The nurse should continue the saline flushes until the pH test reads:
7.40
Rationale: First aid after a chemical burn to the eye consists of irrigation of the eye with copious amounts of tap water for at least 5 minutes. As soon as the initial irrigation is complete, the victim should be rushed to the nearest medical facility. On arrival, eye irrigation should be resumed with water or normal saline for 15 to 20 minutes or until all invasive material is gone and litmus paper reveals a pH of about 7.40. A quick test with litmus can be performed before, during, and after irrigations to determine the pH and to ascertain whether the substance was acid or alkaline. The normal body pH is 7.40.
A nurse educator conducts an informational session for emergency department nurses about smallpox. Which statements by the nurse educator are correct? Select all that apply.
Early clinical manifestations include influenza-like symptoms.
Vaccinating within 3 days of exposure lowers the risk of active disease.
Th infected person is infectious from the onset of the rash until the scabs separate.
Rationale: Clinical manifestations of smallpox include sudden onset of influenza-like symptoms, including fever, malaise, headache, prostration, severe back pain, and, less often, abdominal pain and vomiting. Two to 3 days later, the temperature falls and the client feels somewhat better, at which time the characteristic rash appears, first on the face, hands, and forearms and then, after a few days, on the trunk. Lesions also develop in the mucous membranes of the nose and mouth and ulcerate very soon after their formation, releasing large amounts of virus into the mouth and throat. Smallpox is transmitted from person to person in infected aerosols and air droplets, especially if the symptoms include coughing. A person is considered infectious at the onset of the rash and until the rash scabs over, which is approximately 3 weeks. Airborne precautions are required even if the nurse has been vaccinated against smallpox, because the vaccine does not give reliable lifelong immunity. Those vaccinated within 2 or 3 days of exposure have a lesser risk of active disease.
A nurse educator conducts an informational session for hospital nurses about skin anthrax. Which statements by the nurse educator are correct? Select all that apply.
Skin anthrax can lead to septicemia if it goes untreated.
Symptoms may appear as soon as 24 hours after exposure.
Contact precautions are not always necessary with skin anthrax
Rationale: Skin anthrax is transmitted through direct contact when spores from contaminated products enter the skin through cuts or abrasions. Person-to-person spread does not occur; therefore, contact precautions may not always be necessary. Symptoms may appear as early as 24 hours or as long as up to 7 days after exposure. Antibiotic treatment cures the skin infection, but, left untreated, skin anthrax results in overwhelming septicemia and death. Inhalation anthrax, transmitted through the inhalation of spores, begins with mild, nonspecific upper respiratory and flulike symptoms, including fever, muscle aches, and fatigue.
A nurse is conducting an admission assessment of a client hospitalized with a diagnosis of Meniere's disease. Which question would elicit information specific to the attacks that occur with this disorder?
"Do you have a feeling of fullness in your ear?"
Rationale: Meniere's disease results from a disturbance in the fluid of the endolymphatic system. The cause of the disturbance is unknown. Attacks may be preceded by a feeling of fullness in the ear or by tinnitus. Headaches, difficulty speaking, and momentary losses of consciousness are not associated with this disorder.
A nurse provides discharge instructions to a client who was hospitalized for an acute attack of Meniere's disease. Which statements by the nurse are correct? Select all that apply.
Position changes should be made slowly.
Underwater swimming should be avoided.
It is best to switch to decaffeinated tea and coffee
If an acute attack occurs, sit down and keep the eyes closed.
Rationale: Meniere's disease results from a disturbance in the fluid of the endolymphatic system. The cause of the disturbance is unknown. If an acute attack of vertigo occurs, the client is instructed to immediately lie down on a firm surface if possible, loosen clothing, and close the eyes until the acute vertigo stops. Between attacks, the client may resume normal activities but should avoid underwater swimming, which may cause a loss of orientation. The nurse encourages the client to follow a low-salt diet and to avoid excessive use of caffeine, sugar, monosodium glutamate, and alcohol. The client should be taught to avoid sudden head movements or position changes.
A client arrives at the emergency department and reports a buzzing sound in his ear. The client tells the nurse that an insect flew into the ear. Which intervention does the nurse take first to remove the insect?
Instilling lidocaine into the ear
Rationale: Insects that make their way into an ear are killed before removal unless they can be coaxed out with the use of a flashlight or a humming noise. Mineral oil, diluted alcohol, or lidocaine (not water) is instilled into the ear canal (or an ether-soaked cotton ball is placed in the ear) to suffocate the insect, which is then removed with the use of ear forceps. When the foreign object is vegetable matter, irrigation is not used, because this material expands with hydration, worsening the impaction becomes worse. Antibiotics may or may not be prescribed after removal of the insect.
A home care nurse, assessing the skin of a client, notes the following rash beneath the skin:
Which precaution will the nurse immediately institute before completing the assessment?
Putting on a gown and gloves
Rationale: Scabies presents as vesicle or pustule irritations, burrows, or rash of the skin, especially in the webbing between the fingers. When a client is infested with scabies, a gown and gloves should be worn for close contact. A mask and head covering are not necessary. Transmission by way of clothing and other inanimate objects is uncommon. Scabies is usually transmitted from person to person by way of direct skin contact. All of the client's contacts should be treated for the infestation at the same time.
A nurse prepares to treat frostbite of the toes of a homeless man who was brought to the emergency department by the police. Which action by the nurse is appropriate?
Continuously rewarming the toes in a warm-water bath for 15 to 20 minutes
Rationale: Acute frostbite is ideally treated with rapid and continuous rewarming of the tissue in a warm-water bath (90˚ to 107˚ F [32.2 to 41.7˚C]) for 15 to 20 minutes or until flushing of the skin occurs. Slow thawing and interrupted periods of warmth are avoided because they contribute to increased cellular damage. Dry heat should never be applied, nor should the frostbitten areas be rubbed or massaged as part of the warming process; these actions may produce further tissue injury. [Show Less]
