Nursing Elites

1. A client with myasthenia gravis (MG) is receiving immunosuppressive therapy. Recent lab tests show decreased serum magnesium. What nursing action is most important?

• A. Observe rhythm on telemetry monitor.
• B. Check for visual difficulties.
• C. Assess for hip and hand joint pain.
• D. Note the most recent hemoglobin level.

Correct answer: A

Rationale: Magnesium plays a crucial role in maintaining normal cardiac rhythms, particularly in patients with cardiac conditions. Abnormal levels can lead to arrhythmias, which is why continuous monitoring of the heart's electrical activity is important. Magnesium's effect on neuromuscular and cardiac function makes it essential to monitor its levels, and any discrepancies can impact treatment decisions. Checking for visual difficulties (choice B) may be important in MG but is not the priority in the context of decreased serum magnesium. Assessing for hip and hand joint pain (choice C) is not directly related to the issue of decreased serum magnesium. Noting the most recent hemoglobin level (choice D) is not the priority in this situation compared to monitoring the cardiac rhythm due to low magnesium levels.

2. A client with a seizure disorder is prescribed phenytoin. What is the most important teaching the nurse should provide?

• A. Take phenytoin with antacids to reduce stomach upset.
• B. Maintain a consistent dosing schedule to prevent seizures.
• C. Monitor for excessive drowsiness and dizziness.
• D. Take the medication at bedtime to reduce seizure risk.

Correct answer: B

Rationale: The most important teaching the nurse should provide to a client prescribed phenytoin is to maintain a consistent dosing schedule to prevent seizures. Phenytoin is an antiepileptic drug, and missing doses can increase the risk of seizures. Option A is incorrect because antacids can interact with phenytoin and reduce its absorption. Option C is important but not the most critical teaching as compared to maintaining a consistent dosing schedule. Option D is incorrect because the timing of phenytoin administration should be consistent rather than specifically at bedtime.

3. The nurse is planning to administer two medications at 0900. Which property of the drugs indicates a need to monitor the client for toxicity?

• A. Short half-life
• B. High therapeutic index
• C. Highly protein-bound
• D. Low bioavailability

Correct answer: C

Rationale: The correct answer is C, 'Highly protein-bound.' Drugs that are highly protein-bound can displace from protein-binding sites, leading to increased free drug levels in the blood, which can result in toxicity. Monitoring the client for toxicity is crucial when administering highly protein-bound drugs. Choices A, B, and D are incorrect. A short half-life does not necessarily indicate a need for monitoring toxicity; a high therapeutic index indicates a wide safety margin between the effective dose and the toxic dose, reducing the risk of toxicity; low bioavailability refers to the fraction of the drug that reaches the systemic circulation unchanged and does not directly relate to the risk of toxicity.

4. The nurse reviews the diagnostic tests prescribed for a client with a positive skin test. Which subjective findings reported by the client support the diagnosis of tuberculosis?

• A. Mucopurulent cough and night sweats
• B. Fatigue and headache
• C. Persistent cough and weight gain
• D. Weight loss and fever

Correct answer: A

Rationale: A mucopurulent cough and night sweats are hallmark signs of active tuberculosis. These symptoms are key indicators of TB as the combination of a productive cough with night sweats is highly suggestive of the disease. Fatigue and headache (choice B) are nonspecific symptoms that can occur in many conditions and are not specific to TB. Persistent cough and weight gain (choice C) are not typical findings in tuberculosis. Weight loss and fever (choice D) can be present in TB, but the specific combination of mucopurulent cough and night sweats is more specific to the diagnosis.

5. The nurse is caring for a client with a traumatic brain injury who is receiving mechanical ventilation. Which assessment finding indicates that the client may be experiencing increased intracranial pressure (ICP)?

• A. Client becomes increasingly lethargic
• B. Client's respiratory rate is 16 breaths per minute
• C. Client responds to verbal stimuli
• D. Client's pupils are equal and reactive

Correct answer: A

Rationale: Increased lethargy is a sign of worsening intracranial pressure, which can be life-threatening in clients with brain injuries. As ICP rises, it can lead to decreased level of consciousness, such as lethargy or even coma. Choices B, C, and D are not indicative of increased ICP. A normal respiratory rate, response to verbal stimuli, and equal reactive pupils do not specifically point towards increased intracranial pressure.
