Correct Answer: B

Rationale: The correct answer is B because turning the patient every 2 hours helps prevent pressure ulcers caused by shearing forces. This intervention redistributes pressure, improving blood flow to the skin, thus reducing the risk of skin breakdown. Administering pain medication (A) does not directly address the skin integrity issue. Monitoring vital signs (C) is important but does not address skin integrity. Keeping bed rails up (D) may actually increase the risk of shearing forces.

Correct Answer: D

Rationale: The correct answer is D: Observe for muscle twitching and numbness or tingling of the lips, fingers, and toes. After a thyroidectomy, the parathyroid glands may be inadvertently damaged, leading to hypocalcemia. Muscle twitching and numbness/tingling are early signs of hypocalcemia. The nurse should monitor for these symptoms to detect and address hypocalcemia promptly. Choice A is incorrect as monitoring thyroid-stimulating hormone levels is not related to hypocalcemia. Choice B is incorrect as it describes signs of potential complications like bleeding or airway obstruction, not hypocalcemia. Choice C is incorrect as changes in voice quality and gastric issues are not specific to hypocalcemia.

Correct Answer: B

Rationale: The correct answer is B because hyperkalemia presents with symptoms such as muscle weakness, diarrhea, and ECG changes. Muscle weakness is a common sign due to potassium's effect on neuromuscular function. Diarrhea can lead to potassium loss. ECG changes, such as peaked T waves and widened QRS complexes, indicate cardiac involvement. Assessing for these symptoms helps monitor the severity of hyperkalemia and guide treatment. Other choices are incorrect because assessing for fever and chest pain (choice A) are not specific to hyperkalemia. Encouraging fluid restriction (choice C) may not directly address hyperkalemia. Preparing for a cardiac ultrasound (choice D) is not an immediate intervention for hyperkalemia.

Correct Answer: A

Rationale: The correct answer is A: Hypocortisolism. After a transsphenoidal hypophysectomy, the pituitary gland is removed or partially removed, leading to decreased cortisol production. Signs of hypocortisolism include weakness, fatigue, hypotension, weight loss, and electrolyte imbalances. Hyperglycemia (B) is not typically associated with this procedure. Hypoglycemia (C) is not a common concern post-hypophysectomy. Hypercalcemia (D) is not directly related to pituitary gland removal. Therefore, assessing for hypocortisolism is crucial for early detection and management post-surgery.

Correct Answer: D

Rationale: The correct answer is D: Cryptorchidism. Cryptorchidism, or undescended testicle, is a known risk factor for testicular cancer as the undescended testicle is more prone to developing cancerous changes. This condition increases the risk of testicular cancer even if the testicle is surgically corrected later in life. Other choices like A (Testosterone therapy during childhood) and B (Sexually transmitted disease) are not linked to testicular cancer. Choice C (Early onset of puberty) is not a direct risk factor for testicular cancer.
