Nursing Elites

1. A client is admitted to the critical care unit after suffering from a massive cerebral vascular accident. The client's vital signs include BP 160/110, HR 42, Cheyne-Stokes respirations. Based on this assessment, the nurse anticipates the client to be in which acid-base balance?

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: A

Rationale: In this scenario, the client is exhibiting Cheyne-Stokes respirations, which are characterized by periods of deep breathing alternating with apnea. This pattern indicates respiratory insufficiency, resulting in an accumulation of carbon dioxide in the blood. The elevated BP and slow heart rate further support the respiratory insufficiency, leading to respiratory acidosis. Therefore, the correct answer is Respiratory acidosis. Choices B, C, and D are incorrect. Respiratory alkalosis is characterized by decreased carbon dioxide levels in the blood, which is not indicated by the client's presentation. Metabolic acidosis results from conditions such as renal failure or diabetic ketoacidosis and is not the primary imbalance in this case. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels, which are not present in the client's vital signs.

2. An infection in a central venous access device is not eliminated by giving antibiotics through the catheter. How might bacterial glycocalyx contribute to this?

• A. It protects the bacteria from antibiotic and immunologic destruction.
• B. Glycocalyx neutralizes the antibiotic, rendering it ineffective.
• C. It competes with the antibiotic for binding sites on the microbe.
• D. Glycocalyx provides nutrients for microbial growth.

Correct answer: A

Rationale: Bacterial glycocalyx is a viscous polysaccharide or polypeptide slime that covers microbes. It plays a significant role in protecting bacteria by enhancing adherence to surfaces, resisting phagocytic engulfment by white blood cells, and preventing antibiotics from contacting the microbe. Choice A is correct because glycocalyx shields the bacteria from both antibiotics and the immune system, allowing the infection to persist. Choices B, C, and D are incorrect because glycocalyx does not neutralize antibiotics, compete for binding sites with antibiotics, or provide nutrients for microbial growth.

3. The nurse is caring for a preschool child who is being treated in the hospital for respiratory syncytial virus (RSV). In planning the client's care, the nurse should recognize that the child is likely to view this illness as?

• A. Punishment.
• B. Disturbance to body image.
• C. Rejection from parents.
• D. Change in routine with friends.

Correct answer: A

Rationale: The correct answer is A: Punishment. Preschool children often see illness as a form of punishment, especially when they are unable to understand the cause of their sickness. This perception is rooted in their limited cognitive abilities and understanding of health concepts. Choices B, C, and D are incorrect because preschool children are less likely to associate illness with disturbance to body image, rejection from parents, or changes in routine with friends. These options are not developmentally appropriate for how preschoolers typically interpret illness.

4. 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.

5. In conducting a community health fair for a group of middle-aged citizens, which statement should the nurse emphasize in reducing the risk of coronary heart disease?

• A. Participate in at least 30 minutes of moderate physical activity 3 to 5 days per week.
• B. Engage in an aerobic exercise class every day.
• C. Limit your alcohol intake to a moderate level.
• D. The best way to lose weight is to follow a balanced diet.

Correct answer: B

Rationale: Engaging in an aerobic exercise class every day is crucial in reducing the risk of coronary heart disease. Aerobic exercises help keep the heart in shape, lower blood pressure, and improve cholesterol levels. It is recommended to participate in at least 150 minutes of moderate-intensity aerobic exercise per week, which can be achieved by engaging in aerobic exercise daily. Choice A has been corrected to emphasize the frequency required to significantly reduce the risk of coronary heart disease. Choice C has been modified to suggest moderation in alcohol intake, as excessive alcohol consumption is harmful. Choice D is also incorrect as a balanced diet, not specifically high-protein, high-fat, is recommended to reduce the risk of coronary heart disease and maintain a healthy weight.
