Nursing Elites

1. Ten hours following thrombolysis for an ST elevation myocardial infarction (STEMI), a client is receiving a lidocaine infusion for isolated runs of ventricular tachycardia. Which finding should the nurse document in the EMR as a therapeutic response to the lidocaine infusion?

• A. Stabilization of BP ranges
• B. Cessation of chest pain
• C. Reduced heart rate
• D. Decreased frequency of episodes of VT

Correct answer: D

Rationale: The correct answer is D. Decreased frequency of ventricular tachycardia (VT) episodes indicates that the lidocaine infusion is effectively managing the ventricular tachycardia. Stabilization of BP ranges (choice A) may not directly correlate with the therapeutic response to lidocaine for VT. Cessation of chest pain (choice B) may indicate pain relief but does not specifically address the effectiveness of lidocaine for VT. Reduced heart rate (choice C) is not a direct indicator of the response to lidocaine for managing VT.

2. A client with COPD is receiving home oxygen therapy. Which instruction is most important for the nurse to include in the discharge teaching?

• A. Increase oxygen flow rate during physical activity
• B. Smoke at least 10 feet away from the oxygen source
• C. Use petroleum jelly to prevent nasal dryness
• D. Ensure the oxygen tank is stored in a secure upright position

Correct answer: D

Rationale: The most important instruction for the nurse to include in the discharge teaching for a client with COPD receiving home oxygen therapy is to ensure the oxygen tank is stored in a secure upright position. This is crucial to prevent accidents such as leaks or falls that can lead to serious injury or damage. Choice A is incorrect as increasing the oxygen flow rate during physical activity without a healthcare provider's guidance can be harmful. Choice B is incorrect as smoking near an oxygen source can cause a fire hazard. Choice C is incorrect as petroleum jelly is flammable and should not be used around oxygen due to the risk of combustion.

3. An adult client is admitted with AIDS and oral candidiasis manifested by several painful mouth ulcers. The nurse delegates oral care to the unlicensed assistive personnel (UAP) and discusses how to assist the client. Which instruction should the nurse provide the UAP?

• A. Assist with personal care, but leave oral care for the nurse to complete.
• B. Provide a soft bristle brush for the client to use during oral care.
• C. Use alcohol-based mouthwash to clean the ulcers.
• D. Apply an antifungal cream to the mouth ulcers.

Correct answer: B

Rationale: The correct answer is B: 'Provide a soft bristle brush for the client to use during oral care.' Providing a soft bristle brush helps reduce trauma to the oral mucosa and assists in oral care. Choice A is incorrect because oral care can be safely delegated to UAPs. Choice C is wrong as alcohol-based mouthwash can further irritate the ulcers. Choice D is incorrect as applying an antifungal cream directly to the mouth ulcers is not the standard treatment for oral candidiasis.

4. A client is receiving a secondary infusion of erythromycin 1 gram in 100 mL dextrose 5% in water (D5W) to be infused in 45 minutes. How many mL/hour should the nurse program the infusion pump?

• A. 100 mL/hour.
• B. 125 mL/hour.
• C. 133 mL/hour.
• D. 150 mL/hour.

Correct answer: C

Rationale: To infuse 100 mL in 45 minutes, the infusion rate should be set to 133 mL/hour (100 mL / 0.75 hours). This calculation is obtained by dividing the total volume to be infused by the total time for infusion (100 mL / 0.75 hours = 133 mL/hour). Therefore, choice C is the correct answer. Choices A, B, and D are incorrect because they do not accurately calculate the infusion rate required to deliver the medication within the specified time frame.

5. Based on this strip, what is the interpretation of this rhythm?

• A. Atrial fibrillation.
• B. Ventricular tachycardia.
• C. Normal sinus rhythm.
• D. Second-degree heart block.

Correct answer: C

Rationale: The correct answer is C, Normal sinus rhythm. Normal sinus rhythm is characterized by a regular rhythm, normal P waves, and a consistent PR interval. In this context, the strip likely shows a normal ECG pattern with these characteristics, indicating a healthy heart rhythm. Choices A, B, and D are incorrect. Atrial fibrillation would show an irregularly irregular rhythm with no discernible P waves. Ventricular tachycardia would display wide QRS complexes and a fast heart rate. Second-degree heart block would exhibit intermittent dropped QRS complexes.
