ATI Proctored Pharmacology Test
1. A client has a new prescription for Diltiazem. Which of the following statements should the nurse include in the teaching?
- A. This medication may cause dry mouth.
- B. You should avoid drinking grapefruit juice.
- C. You may experience a rapid heart rate.
- D. Increase your intake of fiber-rich foods.
Correct answer: B
Rationale: The correct statement to include when teaching a client about Diltiazem is to avoid drinking grapefruit juice. Grapefruit juice can increase the levels of diltiazem in the blood, leading to potential toxicity and increased side effects. It is important for the client to be aware of this interaction to ensure the safe and effective use of the medication. Option A is incorrect because dry mouth is not a common side effect of Diltiazem. Option C is incorrect because Diltiazem is actually used to treat rapid heart rates. Option D is unrelated to the medication and not relevant to the teaching.
2. A client has a new prescription for Losartan. Which of the following laboratory values should the nurse monitor?
- A. Serum potassium
- B. Serum sodium
- C. Serum calcium
- D. Serum magnesium
Correct answer: A
Rationale: Corrected Rationale: Losartan, an angiotensin II receptor blocker (ARB), can cause hyperkalemia by affecting the renin-angiotensin-aldosterone system. Monitoring serum potassium levels is crucial to detect and manage any potential hyperkalemia, which can lead to serious cardiac arrhythmias. Monitoring serum sodium, calcium, or magnesium levels is not typically required when a patient is on Losartan unless there are specific indications or comorbidities that warrant such monitoring.
3. While providing an Angiotensin-converting enzyme (ACE) inhibitor, the patient asks what the action of the drug is. As a healthcare provider, you explain that the action of an ACE inhibitor is:
- A. To lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor angiotensin II
- B. To inhibit reabsorption of sodium back into the body, ultimately increasing urine output and lowering blood pressure
- C. To decrease heart rate and blood pressure by competing with Beta1 and Beta2 receptors in the heart and lungs
- D. To lower blood glucose by stimulating the release of insulin
Correct answer: A
Rationale: ACE inhibitors lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor angiotensin II. Angiotensin II is a potent vasoconstrictor, and by inhibiting its formation, ACE inhibitors help dilate blood vessels, reduce blood pressure, and decrease the workload on the heart. Choice B is incorrect as it describes the mechanism of action of diuretics, not ACE inhibitors. Choice C is incorrect as it refers to the action of beta-blockers, not ACE inhibitors. Choice D is incorrect as it describes the mechanism of action of antidiabetic medications, not ACE inhibitors.
4. What is the classification of furosemide?
- A. Loop diuretic
- B. Anticoagulant
- C. Iron supplement
- D. Anticonvulsant
Correct answer: A
Rationale: Furosemide is classified as a loop diuretic, not an anticoagulant, iron supplement, or anticonvulsant. Loop diuretics, like furosemide, act in the loop of Henle in the kidney to inhibit sodium and chloride reabsorption, leading to increased urine output. This mechanism makes them effective in treating conditions such as edema and hypertension. Therefore, the correct classification for furosemide is a loop diuretic (Choice A).
5. Which of the following is not directly related to the drug toxicity of Ibuprofen?
- A. Nausea
- B. Renal dysfunction
- C. Anemia
- D. Muscle wasting
Correct answer: D
Rationale: Ibuprofen is known to cause adverse effects such as nausea, renal dysfunction, and anemia. However, muscle wasting is not a common toxicity associated with Ibuprofen use. Therefore, the correct answer is D.
