Correct Answer: A

Rationale: The correct answer is A because guidelines for primary stroke prevention recommend using aspirin in individuals whose risk of stroke is high enough for the benefits to outweigh the risks. This is based on assessing individual risk factors such as age, hypertension, diabetes, smoking, and history of cardiovascular diseases to determine if the potential benefits of aspirin therapy in reducing the risk of stroke outweigh the potential risks such as gastrointestinal bleeding. Choices B, C, and D are incorrect because aspirin should not be used regardless of risk level, based on gender, or in specific populations without considering individual risk factors to ensure the benefits outweigh the risks.

Correct Answer: A

Rationale: The correct answer is A: Diuretics. In older adults, diuretics are considered the most appropriate first-line therapy for hypertension due to their effectiveness in reducing blood pressure and preventing complications such as heart failure. Diuretics are well-tolerated, have a long history of use, and are cost-effective. They are especially beneficial in older adults with volume overload or fluid retention. Beta-blockers (B) may be less effective in older adults and can have more side effects. ACE inhibitors (C) are commonly used but may pose risks of hyperkalemia and renal dysfunction in older adults. Calcium channel blockers (D) are effective but may increase the risk of falls and fractures in older adults.

Correct Answer: A

Rationale: The correct answer is A: Acute orchitis. Orchitis is inflammation of the testicle that can cause testicular enlargement and tenderness. In this case, the teenager presents with a swollen and sore left testicle, which aligns with the symptoms of orchitis. The patient's history of upper respiratory symptoms suggests a viral infection, which can lead to orchitis. The normal prostate exam and urine analysis rule out prostatitis. Acute epididymitis typically presents with pain and swelling in the epididymis, not the testicle itself. Torsion of the spermatic cord would present with sudden, severe testicular pain and is an emergency requiring immediate surgical intervention.

Correct Answer: B

Rationale: The correct answer is B: Metabolic problems. The patient's inability to maintain sustained upward hand posture indicates asterixis, a sign of metabolic encephalopathy commonly seen in patients with liver failure due to alcoholism. This is caused by metabolic disturbances affecting the brain's function, leading to confusion and motor abnormalities. It is not indicative of a stroke (A), carpal tunnel syndrome (C), or severe fatigue and weakness (D), as they do not typically present with asterixis or the described palm movements.

Correct Answer: B

Rationale: The correct answer is B: A dull pain or cramp. In peripheral artery disease, calf pain is typically described as a dull ache or cramp due to inadequate blood flow to the muscles during exercise. This pain is known as claudication. Choice A is incorrect as sharp, stabbing pain is not typically associated with peripheral artery disease. Choice C, an electric shock, is more indicative of nerve-related conditions. Choice D, a pulsating pain, is more characteristic of an aneurysm rather than peripheral artery disease.
