ATI Pharmacology Proctored Exam Test Bank | 250 Questions and Answers with Rationales | Latest 2021 / 2022
1. Amikacin (Amikin) is prescribed for a
... [Show More] client with a bacterial infection. The client is instructed to contact the health care provider (HCP) immediately if which of the following occurs?
1. Nausea
2.Lethargy
3.Hearing loss
4. Muscle aches
Rationale:
Amikacin (Amikin) is an aminoglycoside. Adverse effects of aminoglycosides include ototoxicity (hearing problems), confusion, disorientation, gastrointestinal irritation, palpitations, blood pressure changes, nephrotoxicity, and hypersensitivity. The nurse instructs the client to report hearing loss to the HCP immediately. Lethargy and muscle aches are not associated with the use of this medication. It is not necessary to contact the HCP immediately if nausea occurs. If nausea persists or results in vomiting, the HCP should be notified. (most aminoglycoside medication names end in the letters -cin).
2. The nurse is assigned to care for a client with cytomegalovirus retinitis and acquired immunodeficiency syndrome who is receiving foscarnet. The nurse should check the latest results of which of the following laboratory studies while the client is taking this medication?
1. CD4 cell count
2.Serum albumin
3.Serum creatinine
4. Lymphocyte count
Rationale:
Foscarnet is toxic to the kidneys. Serum creatinine is monitored before therapy, two to three times per week during induction therapy, and at least weekly during maintenance therapy. Foscarnet may also cause decreased levels of calcium, magnesium, phosphorus, and potassium. Thus these levels are also measured with the same frequency.
3. The client with acquired immunodeficiency syndrome and Pneumocystis jiroveci infection has been receiving pentamidine isethionate (Pentam 300). The client develops a temperature of 101° F. The nurse does further monitoring of the client, knowing that this sign would most likely indicate:
1. The dose of the medication is too low.
2.The client is experiencing toxic effects of the medication.
3.The client has developed inadequacy of thermoregulation.
4. The result of another infection caused by leukopenic effects of the medication.
Rationale:
Frequent side effects of this medication include leukopenia, thrombocytopenia, and anemia. The client should be monitored routinely for signs and symptoms of infection. Options 1, 2, and 3 are inaccurate interpretations.
4. Saquinavir (Invirase) is prescribed for the client who is human immunodeficiency virus seropositive. The nurse reinforces medication instructions and tells the client to:
1. Avoid sun exposure.
2.Eat low-calorie foods.
3.Eat foods that are low in fat.
4. Take the medication on an empty stomach.
Rationale:
Saquinavir (Invirase) is an antiretroviral (protease inhibitor) used with other antiretroviral medications to manage human immunodeficiency virus infection. Saquinavir is administered with meals and is best absorbed if the client consumes high-calorie, high-fat meals. Saquinavir can cause photosensitivity, and the nurse should instruct the client to avoid sun exposure.
5. Ketoconazole is prescribed for a client with a diagnosis of candidiasis. Select the interventions that the nurse includes when administering this medication. Select all that apply.
1. Restrict fluid intake.
2.Instruct the client to avoid alcohol.
3.Monitor hepatic and liver function studies.
4. Administer the medication with an antacid.
5.Instruct the client to avoid exposure to the sun.
6.Administer the medication on an empty stomach.
Rationale:
Ketoconazole is an antifungal medication. It is administered with food (not on an empty stomach) and antacids are avoided for 2 hours after taking the medication to ensure absorption. The medication is hepatotoxic and the nurse monitors liver function studies. The client is instructed to avoid exposure to the sun because the medication increases photosensitivity. The client is also instructed to avoid alcohol. There is no reason for the client to restrict fluid intake. In fact, this could be harmful to the client.
6. A client with human immunodeficiency virus is taking nevirapine (Viramune). The nurse should monitor for which adverse effects of the medication? Select all that apply.
1. Rash
2.Hepatotoxicity
3.Hyperglycemia
4. Peripheral neuropathy
5.Reduced bone mineral density
Rationale:
Nevirapine (Viramune) is a non-nucleoside reverse transcriptase inhibitors (NRTI) that is used to treat HIV infection. It is used in combination with other antiretroviral medications to treat HIV. Adverse effects include rash, Stevens- Johnson syndrome, hepatitis, and increased transaminase levels. Hyperglycemia, peripheral neuropathy, and reduced bone density are not adverse effects of this medication
7. A nurse is caring for a hospitalized client who has been taking clozapine (Clozaril) for the treatment of a schizophrenic disorder. Which laboratory study prescribed for the client will the nurse specifically review to monitor for an adverse effect associated with the use of this medication?
1. Platelet count
2.Cholesterol level
3.White blood cell count
4. Blood urea nitrogen level
Rationale:
Hematological reactions can occur in the client taking clozapine and include agranulocytosis and mild leukopenia. The white blood cell count should be checked before initiating treatment and should be monitored closely during the use of this medication. The client should also be monitored for signs indicating agranulocytosis, which may include sore throat, malaise, and fever. Options 1, 2, and 4 are unrelated to this medication.
8. Disulfiram (Antabuse) is prescribed for a client who is seen in the psychiatric health care clinic. The nurse is collecting data on the client and is providing instructions regarding the use of this medication. Which is most important for the nurse to determine before administration of this medication?
1. A history of hyperthyroidism
2.A history of diabetes insipidus
3.When the last full meal was consumed
4. When the last alcoholic drink was consumed
Rationale:
Disulfiram is used as an adjunct treatment for selected clients with chronic alcoholism who want to remain in a state of enforced sobriety. Clients must abstain from alcohol intake for at least 12 hours before the initial dose of the medication is administered. The most important data are to determine when the last alcoholic drink was consumed. The medication is used with caution in clients with diabetes mellitus, hypothyroidism, epilepsy, cerebral damage, nephritis, and hepatic disease. It is also contraindicated in severe heart disease, psychosis, or hypersensitivity related to the medication.
9. 105.) A nurse is collecting data from a client and the client's spouse reports that the client is taking donepezil hydrochloride (Aricept). Which disorder would the nurse suspect that this client may have based on the use of this medication?
1. Dementia
2.Schizophrenia
3.Seizure disorder
4. Obsessive-compulsive disorder
Rationale:
Donepezil hydrochloride is a cholinergic agent used in the treatment of mild to moderate dementia of the Alzheimer type. It enhances cholinergic functions by increasing the concentration of acetylcholine. It slows the progression of Alzheimer's disease. Options 2, 3, and 4 are incorrect.
10. Fluoxetine (Prozac) is prescribed for the client. The nurse reinforces instructions to the client regarding the administration of the medication. Which statement by the client indicates an understanding about administration of the medication?
1. "I should take the medication with my evening meal."
2."I should take the medication at noon with an antacid."
3."I should take the medication in the morning when I first arise."
4. "I should take the medication right before bedtime with a snack."
Rationale:
Fluoxetine hydrochloride is administered in the early morning without consideration to meals. Eliminate options 1, 2, and 4 because they are comparable or alike and indicate taking the medication with an antacid or food.
11. A client receiving a tricyclic antidepressant arrives at the mental health clinic. Which observation indicates that the client is correctly following the medication plan?
1. Reports not going to work for this past week
2.Complains of not being able to "do anything" anymore
3.Arrives at the clinic neat and appropriate in appearance
4. Reports sleeping 12 hours per night and 3 to 4 hours during the day
Rationale:
Depressed individuals will sleep for long periods, are not able to go to work, and feel as if they cannot "do anything." Once they have had some therapeutic effect from their medication, they will report resolution of many of these complaints as well as demonstrate an improvement in their appearance.
12. A nurse is performing a follow-up teaching session with a client discharged 1 month ago who is taking fluoxetine (Prozac). What information would be important for the nurse to gather regarding the adverse effects related to the medication?
1. Cardiovascular symptoms
2.Gastrointestinal dysfunctions
3.Problems with mouth dryness
4.Problems with excessive sweating
Rationale:
The most common adverse effects related to fluoxetine include central nervous system (CNS) and gastrointestinal (GI) system dysfunction. This medication affects the GI system by causing nausea and vomiting, cramping, and diarrhea. Options 1, 3, and 4 are not adverse effects of this medication.
13. A client taking buspirone (BuSpar) for 1 month returns to the clinic for a follow-up visit. Which of the following would indicate medication effectiveness?
1. No rapid heartbeats or anxiety
2.No paranoid thought processes
3.No thought broadcasting or delusions
4. No reports of alcohol withdrawal symptoms
Rationale:
Buspirone hydrochloride is not recommended for the treatment of drug or alcohol withdrawal, paranoid thought disorders, or schizophrenia (thought broadcasting or delusions). Buspirone hydrochloride is most often indicated for the treatment of anxiety and aggression.
14. A client taking lithium carbonate (Lithobid) reports vomiting, abdominal pain, diarrhea, blurred vision, tinnitus, and tremors. The lithium level is checked as a part of the routine follow-up and the level is 3.0 mEq/L. The nurse knows that this level is:
1. Toxic
2.Normal
3.Slightly above normal
4. Excessively below normal
Rationale:
The therapeutic serum level of lithium is 0.6 to 1.2 mEq/L. A
level of 3 mEq/L indicates toxicity.
15. A client arrives at the health care clinic and tells the nurse that he has been doubling his daily dosage of bupropion hydrochloride (Wellbutrin) to help him get better faster. The nurse understands that the client is now at risk for which of the following?
1. Insomnia
2.Weight gain
3.Seizure activity
4. Orthostatic hypotension
Rationale:
Bupropion does not cause significant orthostatic blood pressure changes. Seizure activity is common in dosages greater than 450 mg daily. Bupropion frequently causes a drop in body weight. Insomnia is a side effect, but seizure activity causes a greater client risk.
16. A hospitalized client is started on phenelzine sulfate (Nardil) for the treatment of depression. The nurse instructs the client to avoid consuming which foods while taking this medication? Select all that apply.
1. Figs
2.Yogurt
3.Crackers
4. Aged cheese
5 Tossed salad
6. Oatmeal cookies
Rationale:
Phenelzine sulfate (Nardil) is a monoamine oxidase inhibitor(MAOI). The client should avoid taking in foods that are high in tyramine. Use of these foods could trigger a potentially fatal hypertensive crisis. Some foods to avoid include yogurt, aged cheeses, smoked or processed meats, red wines, and fruits such as avocados, raisins, and figs.
17. A nurse is reinforcing discharge instructions to a client receiving sulfisoxazole. Which of the following would be included in the plan of care for instructions?
1. Maintain a high fluid intake.
2.Discontinue the medication when feeling better.
3.If the urine turns dark brown, call the health care provider immediately.
4. Decrease the dosage when symptoms are improving to prevent an allergic response.
Rationale:
Each dose of sulfisoxazole should be administered with a full glass of water, and the client should maintain a high fluid intake. The medication is more soluble in alkaline urine. The client should not be instructed to taper or discontinue the dose. Some forms of sulfisoxazole cause the urine to turn dark brown or red. This does not indicate the need to notify the health care provider.
18. A postoperative client requests medication for flatulence (gas pains). Which medication from the following PRN list should the nurse administer to this client?
1. Ondansetron (Zofran)
2.Simethicone (Mylicon)
3.Acetaminophen (Tylenol)
4. Magnesium hydroxide (milk of magnesia, MOM)
Rationale:
Simethicone is an antiflatulent used in the relief of pain caused by excessive gas in the gastrointestinal tract. Ondansetron is used to treat postoperative nausea and vomiting. Acetaminophen is a nonopioid analgesic. Magnesium hydroxide is an antacid and laxative.
19. A client received 20 units of NPH insulin subcutaneously at 8:00 AM. The nurse should check the client for a potential hypoglycemic reaction at what time?
1. 5:00 PM
2. 10:00 AM
3. 11:00 AM
4. 11:00 PM
Rationale:
NPH is intermediate-acting insulin. Its onset of action is 1 to 2½ hours, it peaks in 4 to 12 hours, and its duration of action is 24 hours. Hypoglycemic reactions most likely occur during peak time.
20. A nurse administers a dose of scopolamine (Transderm-Scop) to a postoperative client. The nurse tells the client to expect which of the following side effects of this medication?
1. Dry mouth
2.Diaphoresis
3.Excessive urination
4. Pupillary constriction
Rationale:
Scopolamine is an anticholinergic medication for the prevention of nausea and vomiting that causes the frequent side effects of dry mouth, urinary retention, decreased sweating, and dilation of the pupils. The other options describe the opposite effects of cholinergic-blocking agents and therefore are incorrect.
21. A nurse is caring for a client with hyperparathyroidism and notes that the client's serum calcium level is 13 mg/dL. Which medication should the nurse prepare to administer as prescribed to the client?
1. Calcium chloride
2.Calcium gluconate
3.Calcitonin (Miacalcin)
4. Large doses of vitamin D
Rationale:
The normal serum calcium level is 8.6 to 10.0 mg/dL. This client is experiencing hypercalcemia. Calcium gluconate and calcium chloride are medications used for the treatment of tetany, which occurs as a result of acute hypocalcemia. In hypercalcemia, large doses of vitamin D need to be avoided. Calcitonin, a thyroid hormone, decreases the plasma calcium level by inhibiting bone resorption and lowering the serum calcium concentration.
22. Oral iron supplements are prescribed for a 6-year-old child with iron deficiency anemia. The nurse instructs the mother to administer the iron with which best food item?
1. Milk
2.Water
3.Apple juice
4. Orange juice
Rationale:
Vitamin C increases the absorption of iron by the body. The mother should be instructed to administer the medication with a citrus fruit or a juice that is high in vitamin C. Milk may affect absorption of the iron. Water will not assist in absorption. Orange juice contains a greater amount of vitamin C than apple juice.
23. Salicylic acid is prescribed for a client with a diagnosis of psoriasis. The nurse monitors the client, knowing that which of the following would indicate the presence of systemic toxicity from this medication?
1. Tinnitus
2.Diarrhea
3.Constipation
4. Decreased respirations
Rationale:
Salicylic acid is absorbed readily through the skin, and systemic toxicity (salicylism) can result. Symptoms include tinnitus, dizziness, hyperpnea, and psychological disturbances. Constipation and diarrhea are not associated with salicylism.
24. The camp nurse asks the children preparing to swim in the lake if they have applied sunscreen. The nurse reminds the children that chemical sunscreens are most effective when applied:
1. Immediately before swimming
2.15 minutes before exposure to the sun
3.Immediately before exposure to the sun
4. At least 30 minutes before exposure to the sun [Show Less]
