Correct Answer: D

Rationale: The correct answer is D: “You must avoid hyperextending your neck after surgery.” This is because hyperextending the neck can put excessive strain on the surgical site, leading to potential complications such as bleeding or injury to the incision. Keeping the neck in a neutral position helps promote healing and reduces the risk of complications. A: “The head of your bed must remain flat for 24 hours after surgery.” - Incorrect. Elevating the head of the bed can help reduce swelling and promote drainage after thyroidectomy. B: “You should avoid deep breathing and coughing after surgery.” - Incorrect. Deep breathing and coughing are important to prevent respiratory complications such as pneumonia. C: “You won’t be able to swallow for the first day or two.” - Incorrect. Swallowing may be difficult initially but should improve gradually after surgery.

Correct Answer: D

Rationale: The correct answer is D: Pallor, tachycardia, and a sore tongue. Pernicious anemia is caused by a deficiency in vitamin B12, leading to symptoms such as pallor (due to decreased red blood cells), tachycardia (as the heart works harder to compensate for decreased oxygen-carrying capacity of the blood), and a sore tongue (due to inflammation of the tongue). Choice A is incorrect because bradycardia would not be expected in pernicious anemia, and reduced pulse is not a typical finding. Choice B is incorrect because weight gain is not a common symptom of pernicious anemia. Choice C is incorrect because angina and double vision are not typical findings of pernicious anemia, and anorexia is more likely due to other causes.

Correct Answer: A

Rationale: The correct answer is A because it meets the goal of maintaining a heart rate of 78 beats/min. This specific date ensures the consistency of the heart rate within the desired range. Choices B, C, and D do not align with the goal as they either have a different heart rate or occur on a different date. Therefore, A is the only option that accurately reflects the goal being met on the specified date.

Correct Answer: A

Rationale: The correct answer is A: Detects the presence of malignant cells. Biopsy involves taking a sample of tissue to examine under a microscope for the presence of abnormal or cancerous cells. This procedure is crucial for diagnosing cancer accurately. Choice B (Measures hemoglobin content) is incorrect because hemoglobin content is typically measured through blood tests, not biopsies. Choice C (Measures the RBC size) is incorrect as RBC size is usually assessed through a complete blood count (CBC) test, not a biopsy. Choice D (Detects arterial occlusion) is incorrect because arterial occlusion is typically diagnosed through imaging studies like Doppler ultrasound or angiography, not through a biopsy procedure.

Correct Answer: B

Rationale: Severe and extensive hemolysis leads to the release of large amounts of hemoglobin into the bloodstream, causing hemoglobinemia. This can result in hemoglobinuria, leading to acute renal failure and ultimately shock. Shock is the correct answer as it is a severe consequence of extensive hemolysis. Leg ulcers (A) may occur in conditions like peripheral arterial disease. Priapism (C) is unrelated to hemolysis. Compromised growth (D) is not a common consequence of hemolysis.
