Correct Answer: C

Rationale: Elevating the head of the bed is the correct answer because it helps to promote venous drainage, reduce cerebral edema, and decrease intracranial pressure (ICP). By positioning the patient with the head elevated, gravity assists in preventing further increases in ICP. Encouraging fluids may lead to fluid overload and exacerbate cerebral edema. Providing physical therapy and frequent repositioning may increase ICP by causing unnecessary movement and potential strain on the patient's head and neck.

Correct Answer: B

Rationale: The correct answer is B: "I will press the button whenever I feel pain." This answer demonstrates understanding of how patient-controlled analgesia (PCA) works, where the client self-administers medication when needed for pain relief. Option A is incorrect as the machine is programmed with lockout intervals to prevent overdosing. Option C is incorrect as the client should only press the button when experiencing pain, not on a fixed schedule. Option D is incorrect as PCA does not guarantee complete pain elimination. The key in PCA is empowering the client to self-administer medication based on their pain level.

Correct Answer: B

Rationale: The correct answer is B: Tachycardia. Levothyroxine is a synthetic form of thyroid hormone used to treat hypothyroidism. If the dose is too high, it can lead to symptoms of hyperthyroidism, including tachycardia (rapid heartbeat). This is because an excess of thyroid hormone can increase the heart rate. Dysuria (choice A) is not a common adverse effect of levothyroxine. Leg cramps (choice C) are more commonly associated with electrolyte imbalances. Blurred vision (choice D) is not a typical adverse effect of levothyroxine.

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.

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.
