Nursing Elites

1. The healthcare provider prescribes an IV infusion of isoproterenol in D5W at 300 mcg/hour. How many ml/hour should the nurse set the pump to?

• A. 100 ml/hour
• B. 75 ml/hour
• C. 60 ml/hour
• D. 125 ml/hour

Correct answer: B

Rationale: To calculate the correct infusion rate, convert 300 mcg/hour to mg/hour (300 mcg = 0.3 mg). Since the IV solution is 1 mg in 250 ml, the rate is calculated as 0.3 mg/hour = 75 ml/hour. Therefore, the nurse should set the pump to 75 ml/hour. Choice A (100 ml/hour) is incorrect as it does not reflect the accurate calculation. Choice C (60 ml/hour) is incorrect as it is lower than the correct rate. Choice D (125 ml/hour) is incorrect as it is higher than the correct rate.

2. The healthcare provider is performing a physical assessment on a client who just had an endotracheal tube inserted. Which finding would call for immediate action by the healthcare provider?

• A. Breath sounds are audible bilaterally
• B. Mist is visible in the T-piece
• C. Pulse oximetry of 88
• D. Client is unable to verbalize

Correct answer: C

Rationale: A pulse oximetry reading of 88 indicates hypoxia, which is a serious condition requiring immediate intervention. Adequate oxygenation is crucial for the client's well-being. Choices A and B are normal findings after endotracheal intubation. Hearing bilateral breath sounds and seeing mist in the T-piece indicate proper functioning of the endotracheal tube. While choice D may indicate an issue with speaking due to the endotracheal tube, it is not as critical as the hypoxia indicated by the low pulse oximetry reading.

3. A client who has been prescribed multiple antihypertensive medications experiences syncope and has a blood pressure of 70/40. What is the rationale for the nurse to hold the next scheduled antihypertensive dose?

• A. Increased urinary clearance of the medications has produced diuresis, lowering the blood pressure.
• B. The antagonistic interaction of the medications has reduced their effectiveness.
• C. The synergistic effect of the medications has resulted in drug toxicity, causing hypotension.
• D. The additive effect of the medications has lowered the blood pressure too much.

Correct answer: D

Rationale: The additive effect of multiple antihypertensive medications can cause hypotension, leading to dangerously low blood pressure. In this scenario, the client experiencing syncope with a blood pressure of 70/40 indicates severe hypotension, likely due to the combined action of the antihypertensive medications. Holding the next scheduled dose is essential to prevent further lowering of blood pressure and potential complications. Choices A, B, and C provide inaccurate explanations and do not align with the client's presentation and the need to manage hypotension caused by the additive effect of the medications.

4. A client with hypothyroidism is prescribed levothyroxine. What is the most important teaching point for the nurse to provide?

• A. Take the medication with food to avoid stomach upset.
• B. Take the medication at the same time every day to maintain consistent thyroid levels.
• C. Expect increased sensitivity to cold as a side effect of the medication.
• D. Increase the dosage of levothyroxine if symptoms worsen.

Correct answer: B

Rationale: The correct answer is B. Levothyroxine should be taken at the same time every day to maintain stable thyroid hormone levels and ensure effective management of hypothyroidism. Consistent dosing is critical for preventing fluctuations in hormone levels. Choice A is incorrect because levothyroxine is usually recommended to be taken on an empty stomach for optimal absorption. Choice C is incorrect because increased sensitivity to cold is not a common side effect of levothyroxine. Choice D is incorrect because adjusting the dosage without healthcare provider guidance can be dangerous and should not be done independently.

5. A client with a history of adrenal insufficiency is admitted with acute adrenal crisis. The client complains of nausea and joint pain, vital signs show a temperature of 102°F, heart rate of 138, and blood pressure of 80/60. Which intervention should the nurse implement first?

• A. Obtain an analgesic prescription.
• B. Infuse an intravenous fluid bolus.
• C. Administer PRN oral antipyretic.
• D. Cover the client with a cooling blanket.

Correct answer: B

Rationale: In acute adrenal crisis, the priority intervention is to infuse an intravenous fluid bolus to address the hypotension (blood pressure of 80/60) and help stabilize the client's condition. Adequate fluid volume is crucial in managing adrenal insufficiency crisis. Options A, C, and D do not directly address the hypotension and fluid volume depletion that are critical in this situation. Analgesics, antipyretics, and cooling blankets may be considered later, but the immediate focus should be on fluid resuscitation.
