In what direction should a nursing assistant shave a resident's face when using a disposable razor?

Correct Answer: C

Rationale: The correct answer is C: In the direction of hair growth. Shaving in this direction helps prevent irritation and ingrown hairs. It ensures a smoother and safer shaving experience for the resident. Shaving against the hair growth (choice D) can cause cuts, razor burns, and discomfort. Shaving away from the chin (choice A) or toward the chin (choice B) may not follow the natural pattern of hair growth, leading to skin irritation and potential injuries.

Correct Answer: A

Rationale: The correct answer is A: Micturition. Micturition refers to the process of urination, involving the emptying of the bladder through the urethra. This term is commonly used in medical and scientific contexts. Elimination (B) refers to the removal of waste from the body, which can include both urine and feces. Defecation (C) specifically refers to the act of passing feces. Beynation (D) is not a valid term related to the process of urination. Therefore, the correct term synonymous with urination is micturition, making choice A the correct answer.

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: A

Rationale: Step-by-step rationale: 1. Myocardial ischemia is a condition where the heart muscle doesn't receive enough oxygen. 2. Oxygen is crucial for the heart to function properly and generate energy. 3. Lack of oxygen can lead to chest pain (angina) or a heart attack. 4. Therefore, with myocardial ischemia, the person lacks oxygen, making choice A correct. Summary: - Choice A (Oxygen) is correct as myocardial ischemia involves oxygen deficiency. - Choices B, C, and D are incorrect as they are not directly related to the lack of oxygen in myocardial ischemia.

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.
