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: C

Rationale: Step-by-step rationale: 1. Propranolol is a beta-blocker that acts on the heart. 2. It blocks beta-adrenergic receptors, leading to decreased heart rate and contractility. 3. Decreased heart rate and contractility result in reduced cardiac output. 4. Therefore, the correct answer is C - It decreases cardiac output. Summary: A, B, and D are incorrect because propranolol does not increase heart rate, fluid volume, or cardiac contractility.

Correct Answer: B

Rationale: The correct answer is B: To administer antineoplastic chemotherapy. This is because antineoplastic chemotherapy agents are highly irritating and toxic to the surrounding tissues. Using midline and mid clavicular sites for IV therapy in this case can increase the risk of extravasation, leading to tissue damage and potential complications. Incorrect choices: A: To administer solutions with a pH greater than 5 and less than 9 - pH of the solution does not directly affect the choice of site for IV therapy. C: To administer slow, low-volume infusions - Midline and mid clavicular sites can be appropriate for slow, low-volume infusions. D: To administer high-pressure bolus injections - While midline and mid clavicular sites may not be ideal for high-pressure bolus injections, the question specifically mentions IV therapy, not bolus injections.

Correct Answer: A

Rationale: The correct answer is A: Have a digital rectal examination and prostate-specific antigen (PSA) test done yearly. This is because regular screening with both tests can help detect prostate cancer early. The digital rectal exam allows the doctor to feel for any abnormalities in the prostate gland, while the PSA test measures the levels of a specific protein produced by the prostate gland. If there are any concerning findings, further diagnostic tests can be done to confirm prostate cancer. Choice B is incorrect because transrectal ultrasound is not a recommended screening test for prostate cancer. Choice C is incorrect as testicular self-examinations are for detecting testicular cancer, not prostate cancer. Choice D is incorrect as CBC, BUN, and creatinine levels are not specific tests for prostate cancer screening.

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.
