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 factors like hormonal changes and cell mutations over time. At age 50, men are more likely to develop prostate cancer compared to younger ages. Men over 70 have an even higher risk, but the question specifies an age where the risk starts to increase, making 50 the most appropriate choice. Choices A, B, and C are incorrect as they do not reflect the typical age range where prostate cancer risk significantly rises.

Correct Answer: B

Rationale: The correct answer is B: Provide support to an extremity. A sling is used to support and immobilize an injured or weak arm or shoulder. It helps in reducing movement and preventing further injury. Choice A is incorrect because a sling is not used to increase swelling but rather to reduce swelling by providing support. Choice C is incorrect because a sling is not used to immobilize broken bones; it is used to support the limb while the bones heal. Choice D is incorrect because a sling does not inflate or deflate an extremity; it only provides support.

Correct Answer: B

Rationale: The correct answer is B (70 to 100 mg/dl). This range is considered normal for a person without diabetes as it reflects healthy blood glucose levels. Values below 70 may indicate hypoglycemia, while values above 100 may indicate prediabetes or diabetes. Choice A is too low and suggestive of hypoglycemia. Choices C and D are too high and indicate hyperglycemia, which is not normal for someone without diabetes. Therefore, B is the correct answer based on the typical fasting blood glucose range for a healthy individual.

Correct Answer: A

Rationale: The correct answer is A: Bleeding gums. HIV/AIDS can weaken the immune system, leading to oral health issues such as bleeding gums. Pressure injuries, jaundice, and changes in moles are not typical signs or symptoms of HIV/AIDS. Bleeding gums can result from gum disease, a common oral manifestation in individuals with HIV/AIDS due to compromised immunity. Regular dental check-ups are essential for early detection and management.

Correct Answer: B

Rationale: The correct answer is B: Finger. A pulse oximeter measures oxygen saturation in the blood by clipping onto a person's finger. The finger is chosen because it is easily accessible, has good blood flow, and provides accurate readings. Clipping the sensor on the neck (A) is incorrect as it may obstruct blood flow and provide inaccurate readings. The stomach (C) and lower arm (D) are also not ideal locations as they do not have as strong blood flow as the finger, leading to less accurate results.
