ATI Pharmacology Proctored Exam 2024
1. A staff educator is reviewing medication dosages and factors that influence medication metabolism with a group of nurses at an in-service presentation. Which of the following factors should the educator include as a reason to administer lower medication dosages? (Select all that apply.)
- A. Increased renal secretion
- B. Increased medication-metabolizing enzymes
- C. Liver failure
- D. Peripheral vascular disease
Correct answer: C
Rationale: Liver failure impairs metabolism, leading to increased medication concentrations. When liver function is compromised, lower dosages are necessary to prevent adverse effects. Increased renal secretion is not a reason for lower medication dosages, as it primarily affects excretion rather than metabolism. Increased medication-metabolizing enzymes would usually require higher dosages to achieve the desired effect. Peripheral vascular disease does not directly impact medication metabolism or dosage requirements.
2. A client has been prescribed Valsartan. Which of the following adverse effects should the nurse monitor?
- A. Hyperkalemia
- B. Hypoglycemia
- C. Bradycardia
- D. Hypercalcemia
Correct answer: A
Rationale: Corrected Rationale: Valsartan is an angiotensin II receptor blocker (ARB) that can lead to hyperkalemia by inhibiting the action of aldosterone. Hyperkalemia is a potential adverse effect, making it essential for the nurse to closely monitor the client's potassium levels to prevent complications such as cardiac arrhythmias. Incorrect Options Rationale: - Option B, Hypoglycemia, is not a common adverse effect of Valsartan. - Option C, Bradycardia, is not typically associated with Valsartan use. - Option D, Hypercalcemia, is not a known adverse effect of Valsartan; instead, Valsartan can lead to hyperkalemia.
3. A client has a new prescription for a combination of oral NRTIs (abacavir, lamivudine, and zidovudine) for the treatment of HIV. Which of the following statements should the nurse include in teaching the client?
- A. These medications work by blocking HIV entry into cells.
- B. These medications work by weakening the cell wall of the HIV virus.
- C. These medications work by inhibiting enzymes to prevent HIV replication.
- D. These medications work by preventing protein synthesis within the HIV cell.
Correct answer: C
Rationale: The NRTI antiretroviral medications this client is prescribed work by inhibiting the enzyme reverse transcriptase, thus preventing HIV replication. By inhibiting this crucial enzyme, the drug interferes with the virus's ability to replicate and spread in the body. Choice A is incorrect because NRTIs do not block HIV entry into cells. Choice B is incorrect as NRTIs do not weaken the cell wall of the virus. Choice D is incorrect as NRTIs do not prevent protein synthesis within the HIV cell.
4. A client has a prescription for Erythromycin. Which of the following instructions should be included?
- A. Take the medication with food.
- B. Expect your urine to turn dark yellow.
- C. Take the medication with a full glass of milk.
- D. Report persistent diarrhea to your provider.
Correct answer: D
Rationale: The correct answer is D: 'Report persistent diarrhea to your provider.' Erythromycin is known to cause Clostridium difficile-associated diarrhea, which can be severe. Instructing the client to report any persistent diarrhea to their healthcare provider promptly is crucial to prevent complications. Choices A, B, and C are incorrect. Taking Erythromycin with food is generally recommended to reduce stomach upset, but it is not the most critical instruction. Expecting urine to turn dark yellow is not a common side effect of Erythromycin. Taking Erythromycin with a full glass of milk is not necessary and may not be appropriate for all clients, especially those with lactose intolerance or dairy allergies.
5. A client has a new prescription for Clonidine. What instruction should the nurse include during teaching?
- A. Take the medication with food.
- B. Expect to feel drowsy or lightheaded.
- C. Increase your fluid intake.
- D. Avoid foods high in fat.
Correct answer: B
Rationale: The correct instruction when teaching a client about Clonidine is to expect to feel drowsy or lightheaded. Clonidine can cause these side effects, especially when starting the medication. The nurse should advise the client to avoid activities that require alertness until they understand how the medication affects them. Choices A, C, and D are incorrect because taking Clonidine with food, increasing fluid intake, or avoiding foods high in fat are not specific instructions related to managing the side effects of Clonidine.
