Nursing Elites

1. Which of the following body processes is not dependent upon the presence of calcium in the body fluids?

• A. blood clotting
• B. transport of oxygen in the blood
• C. muscle contractions
• D. transmission of nerve impulses

Correct answer: B

Rationale: The transport of oxygen in the blood is carried out by hemoglobin, which does not require calcium; instead, calcium is essential for blood clotting, muscle contraction, and nerve transmission.

2. Studies suggest that leukoplakia is resolved by excess vitamin A (a fat-soluble vitamin), retinoids, and beta-carotene. Leukoplakia is a white plaque that forms on oral mucous membranes.

• A. Both statements are true.
• B. Both statements are false.
• C. The first statement is true; the second is false.
• D. The first statement is false; the second is true.

Correct answer: B

Rationale: Both statements are false. Studies suggest that leukoplakia, a white plaque that forms on oral mucous membranes, can be resolved by vitamin A, retinoids, and beta-carotene. Despite the potential to resolve leukoplakia, relapse is common. Also pertinent, evidence does not indicate that any of these nutrients prevent malignant transformation. The extract provided clarifies that leukoplakia is a white plaque, not an erythematous lesion, and that vitamin A, retinoids, and beta-carotene can help resolve it.

3. You are attending a certification on cardiopulmonary resuscitation (CPR) offered and required by the hospital employing you. This is

• A. professional course towards credits
• B. inservice education
• C. advance training
• D. continuing education

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

4. In monitoring the patient in PACU, the nurse correctly identifies that checking the patient's vital signs is done every:

• A. 1 hour
• B. 5 minutes
• C. 15 minutes
• D. 30 minutes

Correct answer: A

Rationale: Correct Answer: A - Vital signs monitoring in the PACU (Post-Anesthesia Care Unit) is typically done every hour to closely monitor the patient's condition during the immediate postoperative period. This frequency allows the nurse to promptly identify any changes in the patient's vital signs and intervene as necessary. Choice B (5 minutes) is too frequent for routine vital signs monitoring in the PACU and may not allow for a comprehensive assessment of the patient's stability. Choice C (15 minutes) and Choice D (30 minutes) are also not in line with the standard practice of vital signs monitoring in the PACU, which is typically hourly.

5. A nurse is providing discharge teaching about food choices to a client who has hypokalemia. Which of the following foods should the nurse identify as the best source of potassium?

• A. 1 cup grapes
• B. 1 cup shredded lettuce
• C. 1 cup cooked tomatoes
• D. 1 cup apple slices

Correct answer: C

Rationale: Cooked tomatoes are high in potassium, which is crucial for maintaining normal cell function, nerve transmission, and muscle contraction, making them a suitable choice for addressing hypokalemia. Grapes, shredded lettuce, and apple slices do not contain as much potassium as cooked tomatoes, so they are not the best choice for addressing hypokalemia.
