In which position should a nursing assistant place an unconscious resident before giving mouth care?

Correct Answer: B

Rationale: The correct answer is B: Lateral. Placing an unconscious resident in a lateral position helps prevent aspiration and choking during mouth care by allowing fluids to drain easily. Lying them on their side also helps maintain a clear airway. A: Supine position can cause choking and aspiration risk for unconscious residents. C: Fowler's position is not suitable as it may lead to difficulty in swallowing and increased risk of aspiration. D: Prone position is unsafe for an unconscious resident as it can obstruct the airway and make it harder to provide mouth care.

Correct Answer: C

Rationale: The correct answer is C: ¾ inch. This is the recommended insertion length for a prelubricated commercial enema. Inserting the enema too shallow (choices A and B) may not reach the colon effectively, leading to incomplete cleansing. Inserting it too deep (choice D) can cause discomfort or injury. Therefore, option C is the most appropriate length for safe and effective administration of a commercial enema.

Correct Answer: A

Rationale: The correct answer is A: To manufacture testosterone. The male reproductive system includes testes that produce testosterone, the primary male sex hormone. Testosterone is responsible for the development of male reproductive tissues and secondary sexual characteristics. Progesterone (B) is primarily produced by the female reproductive system, specifically the ovaries. Ova (C) are female reproductive cells produced by the ovaries. Estrogen (D) is the primary female sex hormone produced by the ovaries. Therefore, A is the correct answer as it accurately reflects the function of the male reproductive system in producing testosterone.

Correct Answer: D

Rationale: The correct answer is D: Cardiomyopathy. Cardiomyopathy is a condition characterized by weakening of the heart muscle due to enlargement. This weakening impairs the heart's ability to pump blood effectively. A: Coronary artery disease involves blocked heart arteries, not weakening of the heart muscle. B: Angina pectoris is chest pain due to reduced blood flow to the heart muscle, not weakening of the heart muscle. C: Myocardial ischemia refers to reduced blood flow to the heart muscle, not the weakening and enlargement of the heart muscle seen in cardiomyopathy.

Correct Answer: D

Rationale: The correct answer is D: Pleur. The pleura is the double-layered membrane that covers and protects the lungs. The visceral pleura is in direct contact with the lung tissue, while the parietal pleura lines the chest cavity. This protective membrane helps reduce friction during breathing. Plaque (A), Pancreas (B), and Lymph (C) are incorrect choices. Plaque is a buildup of fatty deposits in arteries, not related to the lungs. The pancreas is an organ involved in digestion and hormone regulation, not part of the lung structure. Lymph refers to the fluid and the system that helps the body fight infections, not a membrane covering the lungs.
