ATI Proctored Pharmacology Test
1. A client has a new prescription for Efavirenz, an NNRTI. Which of the following instructions should the nurse include?
- A. Take this medication at bedtime to prevent drowsiness.
- B. Take this medication with a glass of milk.
- C. Take this medication with a glass of juice.
- D. Take this medication at the same time every day.
Correct answer: A
Rationale: The correct instruction is to take Efavirenz at bedtime to prevent drowsiness and manage central nervous system side effects like dizziness and vivid dreams. While it is important to take the medication at the same time daily for consistent blood levels, the emphasis should be on bedtime to minimize the impact of these side effects. Choices B and C suggesting taking the medication with milk or juice are incorrect and not relevant to optimizing Efavirenz therapy.
2. A client has a new prescription for Prednisone. Which of the following laboratory values should the nurse monitor?
- A. Serum potassium
- B. Serum calcium
- C. Serum sodium
- D. Serum glucose
Correct answer: D
Rationale: The correct answer is D, Serum glucose. Prednisone is a corticosteroid that can lead to hyperglycemia. Monitoring serum glucose levels is essential to assess for elevated blood sugar levels. Choices A, B, and C are incorrect as Prednisone does not directly affect potassium, calcium, or sodium levels.
3. During transfusion of a unit of whole blood, a nurse is assessing a client who develops a cough, shortness of breath, elevated blood pressure, and distended neck veins. The nurse should anticipate a prescription for which of the following medications?
- A. Epinephrine
- B. Lorazepam
- C. Furosemide
- D. Diphenhydramine
Correct answer: C
Rationale: The client's symptoms indicate circulatory overload, which can occur during blood transfusions. Furosemide, a loop diuretic, is commonly prescribed in such cases to help relieve manifestations of circulatory overload by promoting diuresis and reducing fluid volume. Epinephrine is used for severe allergic reactions, lorazepam for anxiety or seizures, and diphenhydramine for mild allergic reactions or as a sedative. Therefore, the correct choice is Furosemide (C) to manage circulatory overload during a blood transfusion.
4. A client has a new prescription for Clonidine. Which of the following adverse effects should the nurse monitor?
- A. Drowsiness
- B. Dry mouth
- C. Weight gain
- D. Insomnia
Correct answer: B
Rationale: Dry mouth is a common adverse effect of Clonidine. Clonidine can reduce saliva production, leading to dry mouth. To alleviate this symptom, the client should be advised to increase fluid intake or use sugar-free gum or candy. Monitoring for dry mouth is important to prevent complications such as oral health issues. Drowsiness, weight gain, and insomnia are potential side effects of Clonidine but are less common compared to dry mouth. Therefore, the nurse should prioritize monitoring for dry mouth as it's a more prevalent adverse effect associated with this medication.
5. Which drug undergoes extensive first-pass hepatic metabolism?
- A. Heparin
- B. Insulin
- C. Propranolol
- D. Nitroglycerin
Correct answer: C
Rationale: Propranolol undergoes extensive first-pass hepatic metabolism in the liver. When administered orally, propranolol is extensively metabolized by the liver before reaching systemic circulation, leading to reduced bioavailability. This process is known as first-pass hepatic metabolism, which significantly affects the drug's effectiveness and necessitates higher oral doses compared to other routes of administration. Heparin (Choice A) is not metabolized by the liver but excreted unchanged by the kidneys. Insulin (Choice B) is a peptide hormone that is not subject to significant first-pass metabolism. Nitroglycerin (Choice D) is primarily metabolized in the blood and tissues, bypassing significant first-pass metabolism in the liver.
