Nursing Elites

1. A nurse is caring for a client who has a new prescription for levothyroxine. Which of the following laboratory values should the nurse monitor to determine the effectiveness of the medication?

• A. Calcium
• B. Sodium
• C. Thyroid-stimulating hormone (TSH)
• D. Magnesium

Correct answer: C

Rationale: The correct answer is C: Thyroid-stimulating hormone (TSH). Monitoring TSH levels is crucial to assess the effectiveness of levothyroxine in clients with hypothyroidism. TSH is produced by the pituitary gland and stimulates the thyroid gland to produce thyroid hormones. In hypothyroidism, where the thyroid gland is underactive, administering levothyroxine helps to normalize thyroid hormone levels. Monitoring TSH levels allows the healthcare provider to adjust the levothyroxine dosage to ensure that thyroid hormone levels are within the therapeutic range. Choices A, B, and D (Calcium, Sodium, and Magnesium) are not directly related to assessing the effectiveness of levothyroxine therapy in hypothyroidism and would not provide relevant information regarding the medication's efficacy.

2. A client is 24 hr postoperative following an abdominal aortic aneurysm resection. Which of the following findings is a priority to report?

• A. Serosanguineous drainage on dressing
• B. Abdominal distention
• C. Absent bowel sounds
• D. Urine output of 20 mL/hr

Correct answer: D

Rationale: Urine output less than 30 mL/hr is indicative of decreased kidney function, potentially due to inadequate perfusion or other complications post-aneurysm resection. This finding requires immediate reporting to prevent further complications such as acute kidney injury. Serosanguineous drainage on the dressing, abdominal distention, and absent bowel sounds are also important postoperative assessments but are not as critical as impaired kidney function in this scenario.

3. A nurse is reviewing the laboratory results of a client who has hypokalemia. Which of the following findings should the nurse expect?

• A. Serum potassium 5.4 mEq/L
• B. Flat T waves
• C. Elevated ST segments
• D. Bradycardia

Correct answer: B

Rationale: Flat T waves are a characteristic ECG finding in hypokalemia. Hypokalemia causes a decrease in serum potassium levels, leading to altered cardiac conduction. Flat T waves are associated with hypokalemia-induced cardiac dysrhythmias. Elevated ST segments are typically seen in conditions like myocardial infarction, not in hypokalemia. Bradycardia is not a typical manifestation of hypokalemia; instead, tachycardia may occur due to potassium imbalances affecting the heart's electrical activity.

4. A nurse is preparing to administer dopamine hydrochloride 4 mcg/kg/min via continuous infusion. The client weighs 80 kg. How many mL/hr should the nurse set the IV infusion to deliver?

• A. 6 mL/hr
• B. 8 mL/hr
• C. 12 mL/hr
• D. 16 mL/hr

Correct answer: A

Rationale: To calculate the correct rate, use the formula: (4 mcg/kg/min * 80 kg) / 800 mcg in 250 mL = 6 mL/hr. This calculation is based on the dose ordered (4 mcg/kg/min) multiplied by the patient's weight in kg (80 kg), divided by the concentration of the drug available (800 mcg in 250 mL) to be infused over 1 hour. Therefore, the correct answer is 6 mL/hr. Choices B, C, and D are incorrect as they do not reflect the accurate calculation based on the provided information.

5. A client with a new prescription for levothyroxine is receiving discharge teaching. Which of the following client statements indicates an understanding of the teaching?

• A. I should take this medication with food to prevent nausea.
• B. I will take this medication every morning before breakfast.
• C. I will stop taking this medication if I experience chest pain.
• D. I will take this medication at bedtime.

Correct answer: B

Rationale: The correct answer is B. Levothyroxine should be taken every morning before breakfast to enhance absorption and maintain consistent thyroid hormone levels. Option A is incorrect because levothyroxine should be taken on an empty stomach. Option C is incorrect because chest pain is not a common side effect of levothyroxine and stopping the medication abruptly can be harmful. Option D is incorrect because taking levothyroxine at bedtime may result in decreased absorption due to interactions with food and other medications.
