Nursing Elites

1. The nurse is caring for a client with a history of seizure disorder who is receiving phenytoin (Dilantin). Which laboratory value is most important to monitor?

• A. Phenytoin level
• B. Sodium level
• C. Hemoglobin level
• D. White blood cell count

Correct answer: A

Rationale: Corrected Rationale: Monitoring the phenytoin level is crucial to ensure it is within the therapeutic range and to prevent toxicity. Monitoring sodium level is important in clients receiving lithium, not phenytoin. Hemoglobin level and white blood cell count are not directly related to phenytoin therapy monitoring.

2. The nurse is assessing a client with congestive heart failure who is receiving furosemide (Lasix). Which laboratory value should the nurse monitor closely?

• A. Sodium level
• B. Potassium level
• C. Calcium level
• D. Chloride level

Correct answer: B

Rationale: The correct answer is B: Potassium level. Furosemide is a loop diuretic that can cause potassium loss, leading to hypokalemia. Monitoring the potassium level is crucial to prevent complications such as cardiac arrhythmias. Sodium level (choice A) is not typically affected by furosemide. Calcium level (choice C) and chloride level (choice D) are also not the primary focus of monitoring when a client is on furosemide for heart failure.

3. A client with a diagnosis of hypothyroidism is prescribed levothyroxine (Synthroid). What is the most important instruction the nurse should provide?

• A. Take the medication in the morning on an empty stomach
• B. Take the medication with food
• C. Report any symptoms of hyperthyroidism
• D. Do not discontinue the medication abruptly

Correct answer: C

Rationale: The correct answer is C: 'Report any symptoms of hyperthyroidism.' Symptoms of hyperthyroidism, such as palpitations or tremors, may indicate an excessive dose of levothyroxine and should be reported to the healthcare provider for proper adjustment of the medication. Choice A is incorrect because levothyroxine is usually taken in the morning on an empty stomach to maximize absorption. Choice B is incorrect because taking levothyroxine with food can interfere with its absorption. Choice D is incorrect because discontinuing levothyroxine abruptly can lead to a worsening of hypothyroidism symptoms.

4. A 9-year-old is receiving vancomycin 400 mg IV every 6 hours for a methicillin-resistant (Beta-lactam-resistant) Staphylococci aureus (MRSA) infection. The medication is diluted in a 100 mL bag of saline with instructions to infuse over one and a half hours. How many mL/hour should the nurse program the infusion pump?

• A. 50
• B. 67
• C. 57
• D. 70

Correct answer: B

Rationale: To calculate the infusion rate for vancomycin, you need to divide the total volume by the total time of infusion. In this case, the total volume is 100 mL, and the total time is 1.5 hours. Therefore, 100 mL ÷ 1.5 hours = 67 mL/hour. This means the nurse should program the infusion pump to deliver vancomycin at a rate of 67 mL/hour. Choice A (50) is incorrect as it does not reflect the correct calculation. Choice C (57) is incorrect as it is not the accurate calculation based on the provided information. Choice D (70) is incorrect as it does not correspond to the correct infusion rate calculation.

5. A client with a history of asthma is experiencing wheezing and shortness of breath. What is the priority nursing intervention?

• A. Administer a bronchodilator as prescribed
• B. Encourage the client to drink fluids
• C. Place the client in an upright position
• D. Assess the client's peak flow rate

Correct answer: A

Rationale: Administering a bronchodilator as prescribed is the priority nursing intervention for a client experiencing wheezing and shortness of breath due to asthma. Bronchodilators help relieve bronchoconstriction, allowing better airflow and improving breathing. Encouraging the client to drink fluids may be beneficial in certain situations, but it is not the priority when the client is in respiratory distress. Placing the client in an upright position, not supine, can facilitate easier breathing by allowing the chest to expand fully. While assessing the client's peak flow rate is important in asthma management, in this acute situation, the priority is to provide immediate relief by administering the bronchodilator.
