Correct Answer: D

Rationale: The correct answer is D because it accurately reflects the patient's chief complaint of having black stools in the last 24 hours, which is a concerning symptom suggestive of gastrointestinal bleeding. This documentation is specific and focused on the reason for seeking care, prioritizing the urgent nature of the symptom. Choice A is incorrect because it does not mention the presenting symptom of black stools. Choice B is incorrect as it does not directly state the reason for seeking care. Choice C is incorrect as it focuses on the patient's self-diagnosis of ulcerative colitis rather than the current concerning symptom of black stools.

Correct Answer: B

Rationale: The correct answer is B because increasing physical activity and reducing stress are important lifestyle changes for managing chronic hypertension. Exercise helps lower blood pressure and stress reduction techniques can help control hypertension. Option A is incorrect as reducing sodium intake, not increasing it, is recommended. Option C is incorrect as medications for hypertension should be taken as prescribed, not only when blood pressure increases. Option D is incorrect as monitoring blood pressure should be done regularly, but not necessarily every week.

Correct Answer: B

Rationale: Acyclovir is a nucleoside analog antiviral drug that is specifically effective against herpes simplex virus (HSV) types 1 and 2, as well as varicella-zoster virus (VZV). The drug works by inhibiting viral DNA synthesis. HSV and VZV are both members of the herpes virus family, and acyclovir is most commonly prescribed for infections caused by these viruses. Therefore, the correct answer is B. Choice A (HIV) is incorrect because acyclovir is not effective against HIV. Choice C (CMV) is incorrect because acyclovir is less effective against cytomegalovirus (CMV) compared to HSV and VZV. Choice D (influenza A viruses) is incorrect because acyclovir is not indicated for the treatment of influenza viruses.

Correct Answer: B

Rationale: The correct answer is B because asking someone who knows the patient well can provide valuable insight into the meaning behind the verbal and nonverbal communication discrepancy. This helps in understanding the context and potential reasons for the inconsistency. Option A is incorrect as ignoring nonverbal behaviors can lead to missing important cues. Option C of interpreting messages as an 'average' may oversimplify the complexity of communication. Option D is incorrect as while nonverbal behaviors can provide valuable information, solely focusing on them may not give a complete understanding of the situation.

Correct Answer: A

Rationale: The correct answer is A: Administer nitroglycerin. Nitroglycerin is the recommended initial medication for chest pain in a client with a history of myocardial infarction. It helps dilate blood vessels, improving blood flow to the heart, and reducing chest pain. Aspirin (choice B) is also usually given to reduce blood clot formation, but nitroglycerin is the priority for immediate relief. Morphine (choice C) may be used if nitroglycerin is ineffective, and beta blockers (choice D) are typically used for long-term management of heart conditions, not for immediate relief of chest pain.
