Nursing Elites

1. Which client is at risk for hypomagnesemia?

• A. Client with a history of heart disease
• B. Client taking magnesium-based antacids
• C. Client with a parathyroid disorder
• D. Client admitted with alcohol abuse

Correct answer: D

Rationale: The correct answer is the client admitted with alcohol abuse. Alcoholics tend to have poor nutrition due to decreased food intake, which is a common source of magnesium. Additionally, alcohol suppresses the release of ADH, leading to diuresis and magnesium loss. Choice A is incorrect because a history of heart disease does not directly increase the risk of hypomagnesemia. Choice B is incorrect as taking magnesium-based antacids would not put the client at risk for hypomagnesemia; in fact, it would help prevent it. Choice C is also incorrect as a parathyroid disorder is not typically associated with an increased risk of hypomagnesemia.

2. A patient asks a nurse the following question: Exposure to TB can be best identified with which of the following procedures?

• A. Chest x-ray
• B. Mantoux test
• C. Breath sounds examination
• D. Sputum culture for Mycobacterium tuberculosis

Correct answer: B

Rationale: The Mantoux test, also known as the tuberculin skin test, is the most appropriate and accurate test to identify exposure to TB. This test involves injecting a small amount of PPD tuberculin under the top layer of the skin, and a positive reaction indicates exposure to the TB bacteria. Choice A, a chest x-ray, is useful for detecting active TB disease but not exposure. Choice C, a breath sounds examination, is not a specific test for TB exposure. Choice D, a sputum culture for Mycobacterium tuberculosis, is used to diagnose active TB infection rather than exposure.

3. A patient had a pneumonectomy to the right lung performed 48 hours ago. Which of the following conditions most likely exists?

• A. Decreased breath sound volume
• B. Elevated tidal volume
• C. Elevated respiratory capacity
• D. Wheezing

Correct answer: A

Rationale: After a pneumonectomy, where a lung is surgically removed, there will be a decrease in breath sound volume on the affected side due to reduced airflow. This reduction in breath sound volume is expected as there is less lung tissue to produce sound. Choices B, C, and D are incorrect. Elevated tidal volume and respiratory capacity are not expected after a pneumonectomy, and wheezing is more commonly associated with conditions like asthma or bronchitis, not a recent pneumonectomy.

4. Which of the following organs of the digestive system has a primary function of absorption?

• A. stomach
• B. pancreas
• C. small intestine
• D. gallbladder

Correct answer: C

Rationale: The small intestine is the correct answer. It is the primary organ responsible for absorption in the digestive system. The stomach's primary function is to break down food through mechanical and chemical digestion. The pancreas produces digestive enzymes to aid in the breakdown of food. The gallbladder stores bile produced by the liver, which helps in the digestion of fats. However, neither the stomach, pancreas, nor gallbladder play the primary role of absorption in the digestive process, making them incorrect choices.

5. A nurse is teaching a client newly diagnosed with Emphysema about the disease process. Which of the following statements best explains the problems associated with emphysema and could be adapted for use in the nurse's discussion with the client?

• A. Hyperactivity of the medium-sized bronchi caused by an inflammatory response leads to wheezing and tightness in the chest.
• B. Larger than normal air spaces and loss of elastic recoil cause air to be trapped in the lung and collapse airways.
• C. Vasodilation, congestion, and mucosal edema cause a chronic cough and sputum production.
• D. Chloride is not being transported properly, producing excess absorption of water and sodium, and thick viscous mucus

Correct answer: B

Rationale: The correct answer is: 'Larger than normal air spaces and loss of elastic recoil cause air to be trapped in the lung and collapse airways.' Emphysema is a breakdown of the elastin and fiber network of the alveoli where the alveoli enlarge or the walls are destroyed. This alveolar destruction leads to the formation of larger-than-normal air spaces. Emphysema is one of a group of pulmonary diseases of a chronic nature characterized by increased resistance to airflow; the entity is part of chronic obstructive pulmonary disease (COPD). Choice A is incorrect because emphysema is not primarily characterized by hyperactivity of the medium-sized bronchi causing wheezing and tightness in the chest. Choice C is incorrect because vasodilation, congestion, and mucosal edema are not the primary mechanisms involved in emphysema, and they do not directly lead to chronic cough and sputum production. Choice D is incorrect because emphysema is not related to chloride transport issues and thick viscous mucus production.
