Correct Answer: C

Rationale: The correct answer is C because life expectancy is influenced by multiple factors such as gender, ethnicity, and living environment. Gender does play a role, but it is not the sole determinant. Ethnicity and living environment also significantly impact life expectancy. Genetic factors may contribute, but they are not the primary factor affecting life expectancy. Therefore, choice C is the most comprehensive and accurate statement. Choices A and B are incorrect as they oversimplify the factors that influence life expectancy, while choice D is also incorrect as it overlooks the significant impact of other factors beyond genetics.

Correct Answer: A

Rationale: The correct answer is A: Nocturia. Nocturia, or waking up at night to urinate, is a common symptom of benign prostatic hypertrophy (BPH) due to the enlarged prostate pressing on the urethra, causing urinary frequency and urgency. Other symptoms like weak urine stream, difficulty starting urination, incomplete emptying, and dribbling may also be present. Recurrent urinary tract infections (B) are less likely to be the initial symptom of BPH, as they are more commonly associated with urinary retention or obstruction. Functional incontinence (C) is not a typical symptom of BPH, as it is more related to mobility or cognitive issues. Hematuria (D) is not a common presenting symptom of BPH, as it is more indicative of other conditions like urinary tract infections or kidney stones.

Correct Answer: B

Rationale: The correct answer is B: Difficulty standing up from a seated position. This is a key indicator of potential sarcopenia because sarcopenia is characterized by age-related loss of muscle mass and strength. Difficulty standing up from a seated position can be attributed to muscle weakness, which is a common symptom of sarcopenia. Unintentional weight loss (A) can be a sign of various health issues, not specific to sarcopenia. Loss of appetite (C) can also be caused by a range of factors, not exclusive to sarcopenia. Increased body fat percentage (D) is not a direct indicator of sarcopenia, as the condition primarily involves muscle loss rather than increased body fat.
