Nursing Elites

1. In evaluating a 10-year-old child with meningitis suspected of having diabetes insipidus, which finding is indicative of diabetes insipidus?

• A. Decreased urine specific gravity.
• B. Elevated urine glucose.
• C. Decreased serum potassium.
• D. Increased serum sodium.

Correct answer: A

Rationale: Diabetes insipidus is characterized by the kidneys' inability to concentrate urine, leading to decreased urine specific gravity. This results in the excretion of large volumes of dilute urine, causing a decrease in urine specific gravity. Therefore, when evaluating a suspected case of diabetes insipidus, a finding of decreased urine specific gravity is indicative of this condition.

2. A client with hepatic encephalopathy is being treated with lactulose. What is an expected outcome of this treatment?

• A. Reduction in blood ammonia levels
• B. Improvement in liver enzyme levels
• C. Decrease in bilirubin levels
• D. Increase in urine output

Correct answer: A

Rationale: Lactulose is used to treat hepatic encephalopathy by reducing blood ammonia levels through promoting its excretion via the intestines. Elevated ammonia levels contribute to the development of encephalopathy symptoms, so by lowering them, the client's neurological status can improve.

3. A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which laboratory test should the nurse monitor to determine the effectiveness of the medication?

• A. Platelet count.
• B. Prothrombin time (PT) and international normalized ratio (INR).
• C. Activated partial thromboplastin time (aPTT).
• D. Fibrinogen level.

Correct answer: B

Rationale: Prothrombin time (PT) and international normalized ratio (INR) are essential laboratory tests to monitor the effectiveness of warfarin (Coumadin) therapy. These tests help assess the clotting time and the desired anticoagulant effect of the medication. Monitoring PT and INR levels is crucial to ensure that the client is within the therapeutic range, reducing the risk of bleeding or clotting complications associated with warfarin therapy. Platelet count (Choice A) measures the number of platelets in the blood and is not specific for monitoring warfarin therapy. Activated partial thromboplastin time (aPTT) (Choice C) is more commonly used to monitor heparin therapy, not warfarin. Fibrinogen level (Choice D) assesses the amount of fibrinogen in the blood and is not a specific test for monitoring warfarin therapy.

4. A client with a history of atrial fibrillation is prescribed dabigatran (Pradaxa). Which instruction should the nurse include in the client's teaching?

• A. Take the medication with food to improve absorption.
• B. Avoid foods high in vitamin K.
• C. Take the medication at the same time each day.
• D. Increase your intake of high-potassium foods.

Correct answer: C

Rationale: The correct instruction for the nurse to include in the client's teaching regarding dabigatran (Pradaxa) is to take the medication at the same time each day. This ensures a consistent blood level and effectiveness of the medication, which is crucial in managing atrial fibrillation and preventing complications. It helps maintain a steady therapeutic effect and reduces the risk of erratic drug levels in the body.

5. A client with hypothyroidism is started on levothyroxine (Synthroid). Which statement by the client indicates a need for further teaching?

• A. I will take this medication every morning before breakfast.
• B. I should have my thyroid levels checked regularly.
• C. If I lose weight, I may need an increased dose.
• D. I can stop taking this medication once my symptoms improve.

Correct answer: D

Rationale: The correct answer is D. Levothyroxine is typically a lifelong therapy for hypothyroidism. It should not be discontinued even if symptoms improve because the medication helps replace the deficient thyroid hormone. Stopping the medication prematurely can lead to a recurrence of symptoms and potential complications. Patients must understand the importance of continuous levothyroxine therapy and the necessity of regular follow-up with their healthcare provider to monitor thyroid levels and adjust the dosage as needed.
