Correct Answer: B

Rationale: Hypotension is a critical sign of anaphylaxis. During anaphylaxis, there is a widespread vasodilation leading to a drop in blood pressure, which manifests as hypotension. This can be accompanied by other symptoms such as swelling, difficulty breathing, hives, and itching. Bradycardia (choice A) is not typically associated with anaphylaxis; instead, tachycardia is more common due to the body's response to the allergic reaction. Increased appetite (choice C) is unrelated to anaphylaxis, as individuals experiencing anaphylaxis often feel unwell and may have nausea or vomiting. Decreased respiratory rate (choice D) is also not a typical finding in anaphylaxis; instead, respiratory distress and wheezing are more commonly observed.

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: B

Rationale: The correct answer is to monitor blood glucose levels before administration. This step is crucial to ensure the correct dose of insulin is administered based on the current blood glucose level. Choice A is incorrect as insulin usually needs to be stored in the refrigerator and has an expiration date. Choice C is incorrect because insulin can be short-acting, rapid-acting, intermediate-acting, or long-acting. Choice D is also incorrect as insulin can have side effects such as hypoglycemia if the dose is too high.

Correct Answer: B

Rationale: The correct answer is B: Hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss through urine, causing hypokalemia. Hyperkalemia (choice A) is not a side effect of furosemide. Hyponatremia (choice C) and hypernatremia (choice D) are related to sodium levels rather than potassium, and they are not typically associated with furosemide use.

Correct Answer: D

Rationale: The correct statement that the nurse should include in the teaching is option D: 'Hospice care continues to help families with grief after a death occurs.' Hospice care not only focuses on providing comfort care for terminal patients but also offers bereavement support to families after the patient's death. Choices A, B, and C are incorrect. Option A is incorrect because hospice care does not provide rehabilitation for the patient; its focus is on comfort and quality of life. Option B is incorrect because hospice care does not aim to extend life but rather to provide quality end-of-life care. Option C is incorrect because hospice care does not transition patients to nursing care; it provides care focused on comfort and symptom management in the patient's preferred setting.
