Nursing Elites

1. Why is a precise amount of oxygen necessary for a patient with COPD to prevent which complication?

• A. Cardiac arrest related to increased partial pressure of carbon dioxide in arterial blood (PaCO2)
• B. Circulatory overload due to hypervolemia
• C. Respiratory excitement
• D. Inhibition of the respiratory hypoxic stimulus

Correct answer: D

Rationale: In patients with COPD, the respiratory drive is often stimulated by low oxygen levels. Administering too much oxygen can inhibit this hypoxic drive, leading to respiratory depression and potential respiratory failure. Therefore, it is crucial to carefully regulate the oxygen therapy to prevent the inhibition of the respiratory hypoxic stimulus in COPD patients.

2. Which of the following blood tests should be performed before a blood transfusion?

• A. Prothrombin and coagulation time
• B. Blood typing and cross-matching
• C. Bleeding and clotting time
• D. Complete blood count (CBC) and electrolyte levels

Correct answer: B

Rationale: Before administering a blood transfusion, it is crucial to perform blood typing and cross-matching to ensure compatibility between the donor's blood and the recipient's blood. This process helps prevent adverse reactions such as transfusion reactions, which can be life-threatening. Prothrombin and coagulation time, bleeding and clotting time, as well as CBC and electrolyte levels are important tests in other clinical contexts, but for blood transfusions, blood typing and cross-matching are essential to ensure patient safety.

3. A healthcare professional is providing information about tuberculosis to a group of clients at a local community center. Which of the following manifestations should the professional NOT include in the teaching?

• A. Persistent cough
• B. Weight gain
• C. Fatigue
• D. Night sweats

Correct answer: B

Rationale: Weight gain is not a typical manifestation of tuberculosis. The characteristic symptoms of tuberculosis include a persistent cough, fatigue, and night sweats. Weight loss, not weight gain, is a common symptom associated with tuberculosis due to the impact of the infection on the body's metabolism. Therefore, the healthcare professional should exclude weight gain from the teaching on tuberculosis manifestations.

4. All of the following interventions are correct when using the Z-track method of drug injection except:

• A. Prepare the injection site with alcohol
• B. Use a needle that is at least 1” long
• C. Aspirate for blood before injection
• D. Rub the site vigorously after the injection to promote absorption

Correct answer: D

Rationale: When using the Z-track method of drug injection, it is important to prepare the injection site with alcohol to ensure cleanliness, use a needle that is at least 1” long to reach the muscle tissue, and aspirate for blood before injection to verify correct needle placement. However, rubbing the site vigorously after the injection is not recommended as it can cause medication to leak into subcutaneous tissue, compromising the medication's intended absorption and efficacy.

5. A client is receiving vecuronium for acute respiratory distress syndrome. Which of the following medications should the nurse anticipate administering with this medication?

• A. Fentanyl
• B. Furosemide
• C. Famotidine
• D. Dexamethasone

Correct answer: A

Rationale: Vecuronium is a neuromuscular blocking agent used for muscle relaxation during mechanical ventilation. When administering vecuronium, it is common to also give an opioid analgesic, such as fentanyl, to manage pain and ensure the patient's comfort. Fentanyl is often used in combination with neuromuscular blocking agents to provide balanced anesthesia, making it the appropriate medication to anticipate administering in this scenario.
