Correct Answer: B

Rationale: Correct! When assessing a client for signs of an allergic reaction, a nurse should look for a rash. A rash is a common manifestation of an allergic response, such as contact dermatitis or hives. It is important to recognize and assess rashes promptly as they can indicate an allergic reaction.\nOption A, fever, is not typically a primary sign of an allergic reaction but may occur in severe cases. Option C, fatigue, is a general symptom and not specific to allergic reactions. Option D, increased appetite, is not a common sign of an allergic reaction and is more likely related to other conditions or factors.

Correct Answer: D

Rationale: The correct answer is D because an elevated temperature is a common manifestation of dehydration. Choices A, B, and C are not indicative of dehydration. A urine specific gravity of 1.010 is within normal range, weight gain suggests fluid overload, and a hematocrit of 45% is also within normal limits and not specifically related to dehydration.

Correct Answer: A

Rationale: The correct answer is A: 'Avoid alcohol while taking this medication.' Metronidazole can cause a disulfiram-like reaction with alcohol, leading to symptoms like nausea, vomiting, flushing, and headache. Therefore, clients should be instructed to avoid alcohol consumption. Choice B is incorrect because metronidazole is not considered safe during pregnancy, especially in the first trimester. Choice C is incorrect as metronidazole is not known to cause increased appetite. Choice D is also incorrect as hair loss is not a common side effect of metronidazole.

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: Administering pain medications as prescribed is a priority to manage chronic pain effectively. Pain medications help alleviate the client's discomfort and improve their quality of life. Encouraging physical activity, monitoring for depression, and educating about alternative therapies are important interventions but may not directly address the immediate need for pain relief in a client with chronic pain. Physical activity and alternative therapies can be beneficial as part of a holistic pain management plan, but addressing the pain directly should be the initial priority.
