Nursing Elites

1. Following mitral valve replacement surgery, a client develops PVCs. The healthcare provider orders a bolus of Lidocaine followed by a continuous Lidocaine infusion at a rate of 2 mg/minute. The IV solution contains 2 grams of Lidocaine in 500 mL of D5W. The infusion pump delivers 60 microdrops/mL. What rate would deliver 4 mg of Lidocaine per minute?

• A. 60 microdrops/minute
• B. 20 microdrops/minute
• C. 30 microdrops/minute
• D. 40 microdrops/minute

Correct answer: A

Rationale: To calculate the rate needed to deliver 4 mg/minute of Lidocaine, first, convert 2 grams to milligrams: 2 grams = 2000 mg. Then, set up a ratio between the total amount of Lidocaine (2000 mg) and the total volume of IV solution (500 mL): 2000 mg / 500 mL = 4 mg / x mL. Solving for x, x = 1 mL. Since the infusion pump delivers 60 microdrops per mL, multiplying by 60 microdrops/mL gives the correct rate of 60 microdrops/minute. This rate ensures the desired 4 mg of Lidocaine is delivered per minute. Choices B, C, and D are incorrect as they do not align with the accurate calculation based on the provided information.

2. After a bronchoscopy, what is the most appropriate intervention for a patient with a chronic cough?

• A. Elevate the head of the bed to 80 to 90 degrees.
• B. Keep the patient NPO until the gag reflex returns.
• C. Place the patient on bed rest for at least 4 hours after bronchoscopy.
• D. Notify the health care provider about blood-tinged mucus.

Correct answer: B

Rationale: The correct intervention is to keep the patient NPO until the gag reflex returns after a bronchoscopy. This is important because a local anesthetic is used during the procedure to suppress the gag and cough reflexes. Monitoring the return of these reflexes helps prevent the risk of aspiration and ensures the patient can safely resume oral intake. While blood-tinged mucus can occur after bronchoscopy, it is a common occurrence and not a cause for immediate concern. Placing the patient on bed rest for an extended period is unnecessary, and elevating the head of the bed to a high-Fowler's position is not specifically required post-bronchoscopy.

3. What drives respiration in a patient with advanced chronic respiratory failure?

• A. Hypoxemia
• B. Hypocapnia
• C. Hypercapnia
• D. None of the above

Correct answer: A

Rationale: In patients with advanced chronic respiratory failure, such as those with chronic obstructive pulmonary disease (COPD), the respiratory drive shifts from being primarily stimulated by high levels of carbon dioxide (hypercapnia) to being driven by low oxygen levels (hypoxemia). This shift is due to the body's adaptation to chronic respiratory acidosis and hypoxemia. As a result, hypoxemia becomes the primary stimulus for respiration in these patients. Hypocapnia, a low level of carbon dioxide, is not a common driver of respiration in patients with advanced chronic respiratory failure. Therefore, the correct answer is hypoxemia.

4. A 65-year-old man is prescribed Flomax (Tamsulosin) for Benign Prostatic Hyperplasia. The patient lives in an upstairs apartment. The nurse is most concerned about which side effect of Flomax?

• A. Hypotension
• B. Tachycardia
• C. Back Pain
• D. Difficulty Urinating

Correct answer: A

Rationale: The correct answer is 'Hypotension.' Flomax (Tamsulosin) is known to cause orthostatic hypotension, especially in the elderly, leading to a sudden drop in blood pressure when standing up. This side effect can result in dizziness, falls, and injury, especially concerning for a patient living in an upstairs apartment. Tachycardia (increased heart rate) and back pain are less commonly associated with Flomax use, while difficulty urinating is a symptom that Flomax is intended to improve in patients with Benign Prostatic Hyperplasia.

5. A patient with acute shortness of breath is admitted to the hospital. Which action should the nurse take during the initial assessment of the patient?

• A. Ask the patient to lie down to complete a full physical assessment.
• B. Briefly ask specific questions about this episode of respiratory distress.
• C. Complete the admission database to check for allergies before treatment.
• D. Delay the physical assessment to first complete pulmonary function tests.

Correct answer: B

Rationale: When a patient presents with acute shortness of breath, the initial assessment should focus on gathering specific information relevant to the current episode of respiratory distress. A comprehensive health history or full physical examination can be deferred until the acute distress has been addressed. Asking specific questions helps determine the cause of the distress and guides appropriate treatment. While checking for allergies is important, completing the entire admission database is not a priority during the initial assessment. Likewise, delaying the physical assessment for pulmonary function tests is not recommended as the immediate focus should be on addressing the acute respiratory distress before ordering further diagnostic tests or interventions.
