Nursing Elites

1. A client with a new diagnosis of myasthenia gravis is prescribed pyridostigmine (Mestinon). Which instruction should the nurse include in the client's teaching?

• A. Take the medication with food to prevent gastrointestinal upset.
• B. Take the medication 30 minutes before meals.
• C. Avoid dairy products while taking this medication.
• D. Take the medication at bedtime.

Correct answer: B

Rationale: The correct instruction for a client with myasthenia gravis prescribed pyridostigmine (Mestinon) is to take the medication 30 minutes before meals. This timing is crucial as it helps improve muscle strength for eating and swallowing. By taking the medication before meals, the client can experience enhanced muscle function during mealtime, which is especially important for managing the symptoms of myasthenia gravis. Choices A, C, and D are incorrect. Taking the medication with food may decrease its effectiveness, avoiding dairy products is not necessary, and taking the medication at bedtime does not coincide with the optimal timing for enhancing muscle function during meals.

2. A client with a history of chronic obstructive pulmonary disease (COPD) presents with increasing shortness of breath. Which assessment finding is most important for the nurse to report to the healthcare provider?

• A. Barrel-shaped chest.
• B. Use of accessory muscles to breathe.
• C. Oxygen saturation of 88%.
• D. Respiratory rate of 22 breaths per minute.

Correct answer: C

Rationale: An oxygen saturation of 88% indicates hypoxemia, which is a critical finding in a client with COPD. Hypoxemia can lead to serious complications and may require immediate intervention, such as adjusting oxygen therapy to improve oxygenation levels and prevent further respiratory distress. Monitoring and maintaining adequate oxygen saturation is crucial in managing COPD exacerbations and preventing respiratory failure.

3. What should be monitored to evaluate the effectiveness of enoxaparin in a patient with deep vein thrombosis (DVT)?

• A. Prothrombin time (PT)
• B. Partial thromboplastin time (PTT)
• C. International normalized ratio (INR)
• D. Platelet count

Correct answer: C

Rationale: The international normalized ratio (INR) is the appropriate parameter to monitor the effectiveness of enoxaparin in preventing clot formation in patients with deep vein thrombosis (DVT). INR reflects the clotting ability of the blood and is commonly used to assess the therapeutic range of anticoagulant medications, such as enoxaparin, which is crucial in managing and preventing thrombotic events like DVT.

4. A patient with systemic lupus erythematosus (SLE) is prescribed hydroxychloroquine. What is the most important instruction the nurse should give?

• A. Report any vision changes immediately.
• B. Take the medication with milk.
• C. Avoid high-fat foods.
• D. Increase intake of green leafy vegetables.

Correct answer: A

Rationale: The correct instruction for a patient prescribed hydroxychloroquine, especially in the context of systemic lupus erythematosus (SLE), is to report any vision changes immediately. Hydroxychloroquine can potentially cause retinal damage, so prompt reporting and ophthalmologic evaluation are essential in preventing irreversible eye complications. Choices B, C, and D are incorrect because they do not address the significant adverse effect of hydroxychloroquine on vision. Taking the medication with milk, avoiding high-fat foods, or increasing intake of green leafy vegetables are not relevant to the primary concern of monitoring for visual changes.

5. The client has just been diagnosed with Addison's disease. Which clinical manifestation should the nurse expect to find?

• A. Hypertension and hyperglycemia.
• B. Hyperpigmentation and hypotension.
• C. Exophthalmos and tachycardia.
• D. Weight gain and fluid retention.

Correct answer: B

Rationale: Hyperpigmentation and hypotension are classic clinical manifestations of Addison's disease due to decreased cortisol production. Hyperpigmentation occurs due to elevated levels of ACTH, leading to increased melanin synthesis. Hypotension results from aldosterone deficiency, causing sodium loss and volume depletion.
