Nursing Elites

1. A nurse in a pediatric clinic is teaching a newly hired nurse about the varicella roster. Which of the following information should the nurse include?

• A. Children who have varicella are contagious until vesicles are crusted
• B. Children who have varicella should receive the herpes zoster vaccination
• C. Children who have varicella should be placed in droplet precautions
• D. Children who have varicella are contagious 4 days before the first vesicle eruption

Correct answer: A

Rationale: The correct answer is A. Children with varicella are contagious until the vesicles crust over, which is important for preventing transmission. Choice B is incorrect as varicella and herpes zoster are caused by different viruses, so the varicella vaccine is given to prevent varicella, not herpes zoster. Choice C is incorrect because varicella is primarily spread through respiratory secretions, so airborne precautions are recommended, not droplet precautions. Choice D is incorrect as children with varicella are contagious even before the first vesicle eruption, not just 4 days before.

2. What lab value should a healthcare provider monitor for a patient on warfarin therapy?

• A. Potassium
• B. PT/INR
• C. Sodium
• D. Calcium

Correct answer: B

Rationale: The correct answer is B: PT/INR. When a patient is on warfarin therapy, healthcare providers monitor the PT/INR levels to evaluate the effectiveness of the treatment and assess the risk of bleeding. Monitoring potassium, sodium, or calcium levels is not directly related to warfarin therapy and would not provide the necessary information needed to manage the medication effectively.

3. A nurse is caring for a client who has a new prescription for metformin. Which of the following instructions should the nurse include?

• A. Take this medication on an empty stomach.
• B. You should avoid eating foods high in potassium.
• C. You should take this medication with meals to improve absorption.
• D. Take this medication before bed to prevent drowsiness.

Correct answer: C

Rationale: The correct instruction for a client prescribed metformin is to take the medication with meals to improve absorption and reduce gastrointestinal upset. Metformin is typically recommended to be taken with food to minimize side effects. Option A is incorrect as taking metformin on an empty stomach may increase the risk of gastrointestinal side effects. Option B is unrelated as metformin does not interact with potassium-rich foods. Option D is also incorrect as metformin does not cause drowsiness, so there is no need to take it before bed.

4. A nurse is preparing to administer vancomycin IV to a client who has methicillin-resistant Staphylococcus aureus (MRSA). Which of the following actions should the nurse take?

• A. Administer the medication over 60 minutes
• B. Monitor the client's blood glucose level during administration
• C. Infuse the medication rapidly to reduce the risk of infection
• D. Administer the medication using a filter needle

Correct answer: A

Rationale: The correct action the nurse should take is to administer the medication over 60 minutes. This is important because administering vancomycin over 60 minutes helps prevent red man syndrome, a reaction that can occur with rapid infusion. Monitoring the client's blood glucose level (Choice B) is unrelated to vancomycin administration. Infusing the medication rapidly (Choice C) is incorrect and can lead to adverse reactions. Administering the medication using a filter needle (Choice D) is unnecessary for vancomycin administration.

5. What is the best way to assess a patient's respiratory function after surgery?

• A. Check oxygen saturation
• B. Auscultate lung sounds
• C. Check for abnormal breath sounds
• D. Check skin color

Correct answer: A

Rationale: The correct answer is to check oxygen saturation. This is because checking oxygen saturation provides a direct measure of how well the patient is oxygenating post-surgery. It helps healthcare providers assess if the patient is receiving enough oxygen to meet their body's needs. Auscultating lung sounds (choice B) is important to assess respiratory function but may not provide an immediate indication of oxygenation status. Checking for abnormal breath sounds (choice C) is relevant but does not directly assess oxygenation levels. Checking skin color (choice D) can provide some information about oxygenation, but it is not as precise or direct as measuring oxygen saturation.
