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. Which diagnostic test is used to confirm tuberculosis (TB) infection?

• A. Chest X-ray
• B. Sputum culture
• C. Skin test (Mantoux)
• D. MRI

Correct answer: C

Rationale: The Mantoux skin test, also known as the Tuberculin Skin Test (TST), is used to confirm tuberculosis (TB) infection. This test involves injecting a small amount of tuberculin protein derivative under the top layer of the skin and then evaluating the immune system's response to the protein. A positive reaction indicates exposure to the TB bacteria. Chest X-rays are used to detect abnormalities in the lungs caused by TB but are not confirmatory. Sputum culture is used to identify the presence of TB bacteria in the sputum. MRIs are not typically used as a primary diagnostic tool for TB.

3. How should a healthcare professional handle a patient who is refusing to take a prescribed medication?

• A. Immediately give the medication
• B. Assess the reasons for refusal
• C. Document refusal
• D. Explore alternative treatment options

Correct answer: B

Rationale: Assessing the reasons for refusal is crucial as it allows the healthcare professional to understand the patient's concerns, which can range from fear of side effects to cost issues. By identifying the underlying reasons, the healthcare professional can tailor their approach to address these specific concerns, potentially improving medication adherence. Giving the medication immediately (Choice A) without understanding the patient's reasons for refusal can lead to further non-compliance. While documenting refusal (Choice C) is important for legal and tracking purposes, it does not directly address the patient's concerns. Exploring alternative treatment options (Choice D) may be considered after understanding the reasons for refusal, but it is not the initial step in managing medication refusal.

4. A nurse is caring for a client who has deep-vein thrombosis (DVT) and is receiving heparin therapy. Which of the following laboratory values indicates that the client's heparin therapy is effective?

• A. aPTT 75 seconds.
• B. INR 1.2.
• C. Hemoglobin 10 g/dL.
• D. Fibrinogen level 350 mg/dL.

Correct answer: A

Rationale: An aPTT of 75 seconds indicates that heparin therapy is within the therapeutic range for a client with DVT. The activated partial thromboplastin time (aPTT) is used to monitor heparin therapy's effectiveness. Choice B, INR 1.2, is not the correct answer because INR is used to monitor the effectiveness of warfarin, a different anticoagulant, not heparin. Choice C, Hemoglobin 10 g/dL, is not a measure of heparin therapy effectiveness. Choice D, Fibrinogen level 350 mg/dL, is not a specific indicator of heparin therapy effectiveness for DVT.

5. A nurse is reviewing the medical record of a client who has a prescription for spironolactone. Which of the following findings should the nurse report to the provider?

• A. Potassium 5.0 mEq/L
• B. Blood pressure 136/84 mm Hg
• C. Sodium 140 mEq/L
• D. Calcium 9.5 mg/dL

Correct answer: A

Rationale: A potassium level of 5.0 mEq/L is at the upper limit of normal and should be monitored closely in clients taking spironolactone, which is potassium-sparing. Elevated potassium levels can lead to hyperkalemia, especially in individuals on potassium-sparing diuretics like spironolactone. Monitoring and reporting high potassium levels are crucial to prevent potential complications such as cardiac arrhythmias. Blood pressure (choice B), sodium level (choice C), and calcium level (choice D) are not directly related to the use of spironolactone and do not require immediate reporting in this scenario.
