Correct Answer: A

Rationale: The correct answer is A: Hypertensive crisis. The nurse should be most concerned about this option because the patient has a history of hypertension and is experiencing new onset symptoms such as headaches, nausea, and dizziness, which could indicate a sudden and severe increase in blood pressure. This condition, if left untreated, can lead to serious complications such as stroke or heart attack. Summary: - B: Migraine headache is unlikely as the symptoms described are not typical of a migraine. - C: Benign positional vertigo is unlikely as it does not explain the presence of headaches and nausea. - D: Tension headache is less concerning compared to hypertensive crisis, given the patient's history of hypertension and the severity of symptoms.

Correct Answer: D

Rationale: The correct answer is D because it directly addresses the inappropriate behavior, sets a boundary, and communicates the nurse's discomfort in a professional manner. By stating that the comment makes them uncomfortable and asking the patient to refrain from such behavior, the nurse asserts their professionalism while maintaining respect for both parties. Choice A is too abrupt and may escalate the situation. Choice B dismisses the behavior, which is inappropriate. Choice C could be perceived as confrontational and potentially lead to a defensive response from the patient.

Correct Answer: B

Rationale: The correct answer is B, Blood pressure. Dizziness, blurred vision, and nausea can be symptoms of hypotension or hypertension. Assessing the patient's blood pressure first is crucial to determine if the symptoms are related to blood pressure fluctuations. Electrolyte levels (A) and blood glucose levels (C) may be assessed later but do not address the immediate concern. Temperature and respiratory rate (D) are important assessments but are not the priority in this scenario where cardiovascular status needs to be evaluated first.

Correct Answer: A

Rationale: The correct answer is A. Regularly checking blood glucose levels is crucial for diabetic patients to monitor their condition and adjust treatment as needed. This helps in managing blood sugar levels effectively and preventing complications. Choice B is incorrect because stopping insulin abruptly can lead to dangerous fluctuations in blood sugar levels. Choice C is incorrect because while exercise is important for diabetic patients, vigorous exercise every day may not be suitable for everyone and should be discussed with healthcare providers. Choice D is incorrect as carbohydrates are an essential source of energy and nutrients for the body. Diabetic patients can still consume carbohydrates in controlled portions as part of a balanced diet.

Correct Answer: C

Rationale: The correct answer is C because a risk diagnosis involves identifying potential problems that an individual may develop in the future. This type of diagnosis focuses on preemptive measures to prevent or minimize the risk of these potential issues occurring. This is different from options A, B, and D, which do not pertain to future potential problems but rather current levels of wellness, past problems and goals, and strengths respectively. Therefore, option C best aligns with the concept of risk diagnosis in nursing classification.
