Nursing Elites

1. The healthcare provider should utilize data about which of the following to provide information about the nutritional status of a client being evaluated for malnutrition?

• A. triceps skinfold measurement
• B. fasting blood glucose level
• C. hemoglobin A1c level
• D. serum lipid profile results

Correct answer: A

Rationale: Objective anthropometric measurements such as triceps skinfold and mid-arm circumference (MAC), along with weight, are usually used to diagnose malnutrition. Triceps skinfold measurement specifically helps assess body fat and muscle mass, providing valuable information about the client's nutritional status. Fasting blood glucose level, hemoglobin A1c level, and serum lipid profile results are important tests in assessing different aspects of health such as diabetes management and cardiovascular risk, but they are not specific indicators of malnutrition.

2. A client with asthma develops respiratory acidosis. Based on this diagnosis, what should the nurse expect the client's serum potassium level to be?

• A. normal
• B. elevated
• C. low
• D. unrelated to the pH

Correct answer: B

Rationale: In respiratory acidosis, the body retains CO2, leading to increased hydrogen ion concentration and a drop in blood pH. As pH decreases, serum potassium levels increase due to the movement of potassium out of cells to compensate for the acidosis. Elevated serum potassium levels are expected in respiratory acidosis. Choice A ('normal') is incorrect because potassium levels are expected to be elevated in respiratory acidosis. Choice C ('low') is incorrect as potassium levels rise in this condition. Choice D ('unrelated to the pH') is incorrect as serum potassium levels are directly impacted by changes in pH in respiratory acidosis.

3. 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.

4. One drug can alter the absorption of another drug. One drug increases intestinal motility. Which effect does this have on the second drug?

• A. None; absorption of the second drug is not affected.
• B. The increased gut motility decreases the absorption of the second drug.
• C. The absorption of the second drug cannot be predicted.
• D. Less of the second drug is absorbed.

Correct answer: D

Rationale: When one drug increases intestinal motility, it accelerates the movement of the second drug through the system. Since most oral medications are absorbed in the intestine, the faster transit time decreases the absorption of the second drug. Therefore, less of the second drug is absorbed. Choice A is incorrect because the increased gut motility does affect the absorption of the second drug. Choice C is incorrect as the effect of increased intestinal motility on drug absorption can be predicted based on pharmacokinetic principles. Choice B is incorrect as increased gut motility would not increase but decrease the absorption of the second drug.

5. Which of the following should not be included in the teaching for clients who take oral iron preparations?

• A. Mix the liquid iron preparation with antacids to reduce GI distress.
• B. Take the iron with meals if GI distress occurs.
• C. Liquid forms should be taken with a straw to avoid discoloration of tooth enamel.
• D. Oral forms should be taken with juice, not milk.

Correct answer: A

Rationale: The correct answer is to mix the liquid iron preparation with antacids to reduce GI distress. This statement is incorrect because iron should not be mixed with antacids as it can significantly reduce the absorption of iron. Choice B is a good recommendation as taking iron with meals can help reduce gastrointestinal distress. Choice C is also correct as liquid forms of iron should be taken with a straw to prevent the discoloration of tooth enamel. Choice D is incorrect as iron preparations can be taken with juice or water, but not with milk, as calcium in milk can inhibit iron absorption.
