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: C

Rationale: Step 1: Identify the characteristics of the lesion described - dome-shaped, in dermis, benign, closed sac attached to epidermis. Step 2: A cutaneous cyst fits all these characteristics - it is a benign closed sac in the dermis with attachment to the epidermis. Step 3: Keloid (A) is an overgrowth of scar tissue, not a closed sac lesion. Tophi (B) are deposits of uric acid crystals, not a sac. Chondrodermatitis (D) is inflammation of cartilage and skin, not a closed sac lesion. Summary: A cutaneous cyst is the correct choice as it matches all the characteristics given, while the other options do not fit the description provided.

Correct Answer: B

Rationale: The correct answer is B: Streptococcus pneumoniae. This bacterium is the most common cause of community-acquired pneumonia in adults due to its prevalence and ability to cause infections in the lungs. It accounts for a significant portion of pneumonia cases worldwide. Staphylococcus aureus (A) is more commonly associated with healthcare-associated pneumonia. Mycoplasma pneumoniae (C) typically causes atypical pneumonia, which tends to be milder and more common in younger individuals. Pseudomonas aeruginosa (D) is more commonly seen in individuals with underlying health conditions or compromised immune systems, rather than in healthy adults with community-acquired pneumonia.

Correct Answer: D

Rationale: The correct answer is D: Suprapubic. Disorders in the kidneys and ureters typically cause pain in the flank, abdomen, and back due to the location of these organs. The kidneys are located in the flank region, so kidney issues may cause flank pain. Ureters run down towards the bladder, so issues in this area can cause pain in the abdomen and back. Suprapubic pain usually indicates issues with the bladder or lower urinary tract, not the kidneys or ureters. Therefore, suprapubic pain is not typically associated with disorders in the kidneys and ureters.

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.
