Nursing Elites

1. 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.

2. A nurse is assessing a client who has Guillain-Barré syndrome. Which of the following findings should the nurse expect?

• A. Increased urine output.
• B. Hyperactive reflexes.
• C. Hypoactive bowel sounds.
• D. Facial weakness.

Correct answer: D

Rationale: Facial weakness is a common finding in clients with Guillain-Barré syndrome due to muscle weakness. While increased urine output is not typically associated with Guillain-Barré syndrome, hyperactive reflexes are more indicative of conditions like hyperthyroidism or spinal cord injury. Hypoactive bowel sounds are not a classic finding in Guillain-Barré syndrome, making it an incorrect choice.

3. A nurse is caring for a client who has a prescription for furosemide. The nurse should monitor the client for which of the following electrolyte imbalances?

• A. Hypernatremia
• B. Hypokalemia
• C. Hypercalcemia
• D. Hypomagnesemia

Correct answer: B

Rationale: The correct answer is B: Hypokalemia. Furosemide, a loop diuretic, can cause potassium loss leading to hypokalemia. Monitoring potassium levels is crucial as low potassium can result in various complications like cardiac dysrhythmias. Choices A, C, and D are incorrect. Hypernatremia is high sodium levels, which are not typically associated with furosemide use. Hypercalcemia is elevated calcium levels and hypomagnesemia is low magnesium levels, which are not the primary electrolyte imbalances associated with furosemide.

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 has a new prescription for ferrous sulfate. Which of the following instructions should the nurse include in the teaching?

• A. Take this medication on an empty stomach.
• B. Take this medication with milk if it causes stomach upset.
• C. Take this medication with orange juice to increase absorption.
• D. Take an antacid 1 hour after this medication.

Correct answer: C

Rationale: The correct instruction is to take ferrous sulfate with orange juice to increase absorption because the vitamin C content in orange juice enhances iron absorption. Choice A is incorrect because ferrous sulfate should be taken with food to reduce gastrointestinal side effects. Choice B is incorrect because milk can decrease iron absorption. Choice D is incorrect because antacids can reduce the absorption of ferrous sulfate.
