1. When should a patient taking omeprazole be administered the medication?
- A. Before bedtime
- B. After dinner
- C. In the morning on an empty stomach
- D. With the patient's lunch meal
Correct answer: C
Rationale: Omeprazole should be administered in the morning on an empty stomach to maximize its effectiveness. This timing is important as omeprazole works best when taken before a meal to inhibit acid production by the stomach. Taking it on an empty stomach in the morning allows the medication to be absorbed efficiently and provides optimal therapeutic effects throughout the day. Choices A, B, and D are incorrect because taking omeprazole before bedtime, after dinner, or with lunch may not allow the medication to work effectively as it requires an empty stomach for better absorption and action.
2. In the management of nausea due to gastroparesis in a client with Diabetes, which of the following medications may be prescribed?
- A. Lubiprostone
- B. Metoclopramide
- C. Bisacodyl
- D. Loperamide
Correct answer: B
Rationale: Metoclopramide, as a dopamine antagonist, is commonly prescribed to manage nausea and improve gastric motility in clients with diabetic gastroparesis. By enhancing gastric emptying, it can help alleviate symptoms like bloating and nausea associated with gastroparesis. Choice A, Lubiprostone, is primarily used to treat chronic idiopathic constipation and irritable bowel syndrome with constipation, not nausea due to gastroparesis. Choice C, Bisacodyl, is a stimulant laxative used for the treatment of constipation and bowel preparation before procedures, not for nausea associated with gastroparesis. Choice D, Loperamide, is an antimotility agent used to manage diarrhea, not nausea or gastric motility issues seen in gastroparesis.
3. When starting therapy with Lisinopril, a client should be instructed to monitor for which of the following adverse effects?
- A. Tinnitus
- B. Diarrhea
- C. Cough
- D. Weight gain
Correct answer: C
Rationale: The correct answer is C: Cough. Lisinopril, an ACE inhibitor, commonly causes a persistent dry cough as an adverse effect. Clients should be informed to monitor for this side effect and report it to their healthcare provider if it occurs. Choices A, B, and D are incorrect because tinnitus, diarrhea, and weight gain are not commonly associated with Lisinopril therapy.
4. A client has a new prescription for Raltegravir. Which of the following statements should the nurse include in teaching the client?
- A. This medication prevents the virus from entering the cell.
- B. This medication prevents the virus from leaving the cell.
- C. This medication blocks the virus from attaching to the cell.
- D. This medication blocks the virus from replicating in the cell.
Correct answer: D
Rationale: The correct answer is D because Raltegravir works by blocking the integrase enzyme, preventing the virus from integrating its genetic material into the host cell's DNA. By inhibiting this process, viral replication within the host cell is halted. Choices A, B, and C are incorrect because Raltegravir's mechanism of action specifically targets viral replication within the cell, not virus entry, exit, or attachment to the cell.
5. 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.
