What is one reason that a resident might have an order to restrict her fluid intake?

Correct Answer: D

Rationale: The correct answer is D because a resident with a gastrointestinal illness may have restrictions on fluid intake to prevent exacerbating symptoms like diarrhea or vomiting. This restriction helps in managing the illness and preventing dehydration. Choice A (The resident is sleepy) is irrelevant to fluid intake. Choice B (The resident has an order for physical therapy) does not directly impact fluid intake. Choice C (The resident has a weight-reducing diet order) focuses on dietary intake, not fluid intake. Thus, the rationale for the correct answer lies in the direct relationship between gastrointestinal illness and the need for fluid restriction.

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.

Correct Answer: C

Rationale: The correct answer is C: Blurred vision. The first symptom of a cataract is usually blurred vision, as the clouding of the eye's lens affects the clarity of vision. Reduced side vision (A), vomiting (B), and double vision (D) are not typical initial symptoms of cataracts. Blurred vision is the most common and specific early sign, indicating the need for further evaluation and potential treatment for cataracts.
