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 the lateral position prevents aspiration and allows saliva to drain. This position also protects the airway by reducing the risk of choking. The other choices are incorrect: A) Supine can lead to aspiration, C) Fowler's position may not be ideal for an unconscious resident, and D) Prone can obstruct the airway.

Correct Answer: C

Rationale: The correct answer is C: ¾ inch. This length is appropriate for inserting a prelubricated commercial enema into the rectum. Inserting it too shallow (choices A and B) may not reach the desired area for effective administration. Inserting it too deep (choice D) can potentially cause discomfort or injury. Therefore, ¾ inch strikes a balance between reaching the rectum effectively and avoiding unnecessary depth.

Correct Answer: A

Rationale: The correct answer is A because the male reproductive system's primary function is to produce testosterone, a hormone responsible for male characteristics and sperm production. Testosterone is produced in the testes by Leydig cells. Choices B, C, and D are incorrect because progesterone is produced by the female ovaries, ova are produced by the female reproductive system, and estrogen is the primary female sex hormone.

Correct Answer: D

Rationale: The correct answer is D: Cardiomyopathy. Cardiomyopathy is a condition characterized by weakening of the heart muscle due to enlargement, leading to reduced heart function. Coronary artery disease (A) involves blockages in the heart's blood vessels, not weakening of the heart muscle. Angina pectoris (B) is chest pain caused by reduced blood flow to the heart muscle, not weakening of the heart muscle itself. Myocardial ischemia (C) refers to reduced blood flow to the heart muscle, which can lead to heart muscle damage but is not specifically related to weakening and enlargement of the heart muscle as seen in cardiomyopathy.

Correct Answer: D

Rationale: The correct answer is D: Pleur. The pleura is a double-layered membrane that covers and protects the lungs. The outer layer is attached to the chest wall, while the inner layer covers the lungs. This membrane helps to reduce friction during breathing. Plaque (A) is a buildup of fatty deposits in arteries, not related to lung protection. The pancreas (B) is an organ that produces digestive enzymes and insulin, not a membrane covering the lungs. Lymph (C) is a fluid that circulates in the lymphatic system, not a membrane covering the lungs. Therefore, the correct answer is Pleur as it is directly related to the lung's protection and function.
