1. How do ACE inhibitors work?
- A. Block the vasoconstrictor and aldosterone effects of angiotensin II at the receptor site
- B. Block stimulation of beta 1 and beta 2 at the receptor sites
- C. Block the conversion of angiotensin I to the vasoconstrictor angiotensin II
- D. None of the above
Correct answer: C
Rationale: ACE inhibitors work by inhibiting the conversion of angiotensin I to angiotensin II. Angiotensin II is a potent vasoconstrictor, and by blocking its production, ACE inhibitors help dilate blood vessels, reduce blood pressure, and decrease the workload of the heart. Choice A is incorrect because it describes the mechanism of action of angiotensin receptor blockers (ARBs), not ACE inhibitors. Choice B is incorrect as it describes beta-blockers, not ACE inhibitors. Choice D is incorrect as ACE inhibitors do have a specific mechanism of action.
2. When should Montelukast be taken?
- A. At least two hours before exercise
- B. Daily in the evening
- C. Two hours before exercise or daily in the evening
- D. None of the above
Correct answer: B
Rationale: Montelukast should be taken daily in the evening to effectively manage asthma symptoms. Taking it at the same time each day helps maintain a consistent level of the medication in the body, providing optimal control over asthma symptoms and inflammation. Choice A is incorrect because Montelukast should not be taken specifically before exercise, but rather daily. Choice C is incorrect because although taking Montelukast two hours before exercise is not necessary, taking it daily in the evening is essential for its effectiveness. Choice D is incorrect as Montelukast should be taken daily to manage asthma.
3. When assessing a client taking Gemfibrozil, which of the following findings should the nurse identify as an adverse reaction to the medication?
- A. Mental status changes
- B. Tremor
- C. Jaundice
- D. Pneumonia
Correct answer: C
Rationale: Jaundice is an adverse reaction that can occur in clients taking Gemfibrozil due to the potential development of liver impairment. Other symptoms of liver impairment may include anorexia and upper abdominal discomfort. Monitoring for signs of jaundice is crucial to detect and manage adverse effects of the medication promptly. Mental status changes (choice A) are not commonly associated with Gemfibrozil use. Tremor (choice B) is not a typical adverse reaction of Gemfibrozil. Pneumonia (choice D) is not directly linked to Gemfibrozil use but can be a complication in some cases.
4. A client has a new prescription for Lovastatin. Which of the following instructions should be included?
- A. Take this medication on an empty stomach.
- B. Take this medication in the morning.
- C. Take this medication at bedtime.
- D. Increase your intake of potassium-rich foods.
Correct answer: C
Rationale: Lovastatin should be taken at bedtime because cholesterol production in the liver is highest at night, making the medication more effective in reducing cholesterol levels. By taking it at bedtime, the medication aligns with the body's natural rhythm of cholesterol synthesis, optimizing its therapeutic effects.
5. A client is prescribed Amlodipine. Which of the following adverse effects should the nurse monitor?
- A. Tachycardia
- B. Peripheral edema
- C. Hyperglycemia
- D. Hypertension
Correct answer: B
Rationale: Corrected Rationale: Amlodipine, a calcium channel blocker, can lead to peripheral edema as an adverse effect. The nurse should assess the client for swelling in the lower extremities, a common manifestation of this side effect. Monitoring for peripheral edema is crucial to ensure early detection and appropriate management. Tachycardia (Choice A) is not a common adverse effect of Amlodipine. Hyperglycemia (Choice C) is not typically associated with Amlodipine use. Hypertension (Choice D) is the condition for which Amlodipine is prescribed to treat, not an adverse effect of the medication.
