The risk of prostate cancer increases when a man is over the age of

Correct Answer: D

Rationale: The correct answer is D: 50. Prostate cancer risk increases with age due to cell mutations over time. Men over 50 are at higher risk as cell changes accumulate. Answer A (40) is too young for significant risk. Answer B (70) is too late, risk peaks earlier. Answer C (60) is closer but does not capture the critical age range for increased risk.

Correct Answer: B

Rationale: The correct answer is B: Provide support to an extremity. 1. A sling is designed to support and elevate an injured extremity to reduce swelling. 2. It helps immobilize and protect the injured area, promoting healing. 3. It prevents further injury by restricting movement. 4. Choices A, C, and D are incorrect because a sling does not increase swelling, immobilize broken bones, or inflate/deflate an extremity.

Correct Answer: B

Rationale: The correct answer is B (70 to 100 mg/dl) because it represents the normal fasting blood glucose range for a person without diabetes. This range is considered optimal for maintaining stable blood sugar levels. Choice A (46 to 78 mg/dl) is too low and indicative of hypoglycemia. Choices C (105 to 120 mg/dl) and D (115 to 132 mg/dl) are too high and suggest hyperglycemia, which is commonly seen in individuals with diabetes. Maintaining blood glucose within the range of 70 to 100 mg/dl is crucial for overall health and prevention of diabetes-related complications.

Correct Answer: A

Rationale: Step-by-step rationale: 1. Bleeding gums are a common sign of HIV/AIDS due to weakened immune system. 2. Pressure injuries, jaundice, and changes in moles are not specific to HIV/AIDS. 3. Bleeding gums can occur due to oral infections common in HIV/AIDS. 4. Monitoring oral health is crucial in HIV/AIDS management. Summary: Bleeding gums is the correct answer as it is a specific symptom of HIV/AIDS related to oral health. Pressure injuries, jaundice, and changes in moles are not typically associated with HIV/AIDS.

Correct Answer: B

Rationale: The correct answer is B: Finger. A pulse oximeter measures oxygen saturation in the blood, which is typically done through capillaries close to the skin's surface. The finger is an optimal location due to the abundant blood vessels, making it easier to accurately measure oxygen levels. Clipping the sensor on the neck (A), stomach (C), or lower arm (D) would not provide accurate readings as these areas have less blood flow and are not suitable for accurate oxygen saturation measurements.
