Correct Answer: C

Rationale: The correct answer is C because sucralfate should be taken on an empty stomach, 1 hour before meals, and at bedtime to coat the ulcer and protect it from stomach acid. Choice A is incorrect because taking it with meals may reduce its effectiveness. Choice B is incorrect as it should not be taken right before bed. Choice D is incorrect as sucralfate should be taken regularly as prescribed, not just when symptoms occur.

Correct Answer: A

Rationale: The correct answer is A: Blood pressure. Sildenafil, a medication for erectile dysfunction, can cause changes in blood pressure. The nurse should monitor for hypotension as a potential side effect. Monitoring heart rate (choice B) is not a priority when administering sildenafil unless there are pre-existing heart conditions. Temperature (choice C) and respiratory rate (choice D) are typically not directly affected by sildenafil administration, making them less relevant for monitoring in this case.

Correct Answer: A

Rationale: The correct answer is A: 'Eliminate areas of standing water.' Standing water provides breeding grounds for mosquitoes, which spread West Nile virus. By eliminating standing water, individuals can reduce the risk of mosquito breeding and the transmission of the virus. Choices B, C, and D are incorrect. Wearing a mask when outdoors, ensuring food is cooked thoroughly, and avoiding contact with sick individuals are not directly related to primary prevention strategies for West Nile virus.

Correct Answer: C

Rationale: The correct answer is C. Omeprazole is a proton pump inhibitor that can mask symptoms of gastrointestinal bleeding; clients should be monitored for this. Choices A and B are incorrect because omeprazole is usually taken before meals, and while it is important to avoid NSAIDs if possible due to their effects on the stomach, it is not directly related to omeprazole use. Choice D is also incorrect as omeprazole is not typically associated with causing drowsiness.

Correct Answer: C

Rationale: The correct answer is C. A history of recurring bowel inflammation can impact the absorption and effectiveness of arthritis medication. Bowel inflammation can affect the body's ability to absorb the medication properly, leading to decreased effectiveness. Choices A, B, and D do not directly relate to the decreased effectiveness of the arthritis medication. Taking medication with water, skipping doses, or taking anti-inflammatory medication without food may not be ideal practices but are not directly linked to the decrease in effectiveness reported by the client.
