Correct Answer: B

Rationale: The correct answer is B: Macule. A macule is a non-palpable skin lesion smaller than 1 cm in diameter. In this case, the skin lesion described is less than 0.5 cm, making it consistent with a macule. Vesicle (choice A) is a small blister filled with clear fluid, papule (choice C) is a solid, raised skin lesion less than 0.5 cm in diameter, and nodule (choice D) is a palpable, solid lesion larger than 0.5 cm in diameter. Therefore, choices A, C, and D describe skin lesions that do not match the characteristics of the lesion presented in the question.

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: C

Rationale: The correct answer is C: Fecal-oral. Hepatitis A is primarily transmitted through the fecal-oral route, often from consuming contaminated food or water. Choice A, sexual contact, is not a typical mode of transmission for hepatitis A. Choice B, airborne droplets, is more characteristic of diseases like influenza or tuberculosis. Choice D, bloodborne transmission, is more relevant to hepatitis B and C, not hepatitis A.

Correct Answer: B

Rationale: The correct answer is B: Respiratory status. When caring for a client with asthma, it is essential to monitor their respiratory status to detect any changes in breathing or signs of airway obstruction. Monitoring heart rate (choice A) may be important in some situations but is not the priority when managing asthma. Blood glucose levels (choice C) and liver function (choice D) are not directly related to asthma and would not be the primary focus of monitoring for a client with this condition.

Correct Answer: A

Rationale: Increased thirst is a classic symptom of hyperglycemia due to the body trying to eliminate excess glucose through urine, leading to dehydration and increased thirst. Weight gain, decreased urination, and fatigue are not typical signs of hyperglycemia. Weight gain is more commonly associated with conditions like hypothyroidism or fluid retention. Decreased urination is not a typical symptom of hyperglycemia, as high blood sugar levels usually lead to increased urination. Fatigue can be a symptom of hyperglycemia, but it is not as specific or characteristic as increased thirst.
