Nursing Elites

1. A client with pneumonia is receiving oxygen therapy. Which of the following oxygen delivery devices should be used to deliver a precise oxygen concentration?

• A. Nasal cannula
• B. Simple face mask
• C. Venturi mask
• D. Non-rebreather mask

Correct answer: C

Rationale: A Venturi mask should be used to deliver a precise oxygen concentration to a client with pneumonia. Venturi masks are designed to deliver a specific oxygen concentration by mixing oxygen with room air in a precise ratio. This device is ideal for patients who require accurate oxygen delivery, such as those with chronic lung diseases. Nasal cannulas deliver a lower concentration of oxygen and are more suitable for patients with mild respiratory issues. Simple face masks and non-rebreather masks do not provide as precise control over the oxygen concentration as a Venturi mask.

2. A patient is being taught to use TD nitroglycerin patches to treat angina pectoris. What instructions should be included?

• A. Apply a patch every 12 hours
• B. Apply a new patch every morning
• C. Use it only when symptoms appear
• D. Rotate the application site weekly

Correct answer: B

Rationale: The correct answer is to apply a new patch every morning. Nitroglycerin patches should be applied in the morning and removed at bedtime to provide a 14-hour nitrate-free interval, preventing tolerance development. Choice A is incorrect because applying a patch every 12 hours may lead to tolerance. Choice C is incorrect because nitroglycerin patches are used prophylactically, not just when symptoms appear. Choice D is incorrect because rotating the application site weekly is not necessary; the same site can be used as long as there is no skin irritation.

3. A healthcare provider is reviewing the medical record of a client who has a new prescription for cimetidine. Which of the following laboratory findings should the healthcare provider identify as the priority to report to the provider?

• A. Sodium 140 mEq/L
• B. WBC count 9,000/mm3
• C. Aspartate aminotransferase (AST) 50 units/L
• D. Fasting glucose 105 mg/dL

Correct answer: C

Rationale: An elevated AST level is indicative of liver damage, which is the priority finding to report to the provider when administering cimetidine. Elevated liver enzymes can be a sign of liver toxicity or damage. Monitoring liver function is crucial when using cimetidine, as it can sometimes lead to hepatotoxicity. The other laboratory findings are within normal ranges and not directly associated with cimetidine administration.

4. When considering a bone marrow transplant for a client with leukemia, which ethical principle pertains to minimizing harm to the client?

• A. Justice
• B. Nonmaleficence
• C. Autonomy
• D. Beneficence

Correct answer: B

Rationale: The correct answer is B: Nonmaleficence. Nonmaleficence is the ethical principle that emphasizes the obligation to do no harm, making it crucial in medical decision-making. In the context of a bone marrow transplant for a client with leukemia, the primary concern is to minimize harm and avoid causing any unnecessary suffering or adverse effects. Choices A, C, and D are incorrect: Justice relates to fairness in resource allocation and treatment decisions, Autonomy involves respecting the patient's right to make decisions about their own care, and Beneficence refers to the obligation to act in the patient's best interest and promote their well-being, which may involve some level of risk or harm for overall benefit.

5. A nurse is performing a pain assessment for a client who is alert. The nurse should recognize that which of the following measures is the most reliable indicator of pain?

• A. Self-report of pain
• B. Nonverbal behavior
• C. Severity of the condition
• D. Vital signs

Correct answer: A

Rationale: The correct answer is A: Self-report of pain. Pain is a subjective experience, and the most reliable way to assess it is through the client's self-report. While nonverbal behaviors and vital signs can provide additional information, they are not as reliable as the client's own report of pain. The severity of the condition may influence the experience of pain but is not a direct indicator of the client's pain level.
