Nursing Elites

1. A nurse is preparing to administer dopamine hydrochloride at 4 mcg/kg/min for a client weighing 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, you first need to convert the weight to micrograms: 4 mcg/kg/min * 80 kg = 320 mcg/min. Then, convert micrograms to milligrams: 320 mcg/min / 1000 = 0.32 mg/min. Next, calculate how many milligrams per hour: 0.32 mg/min * 60 min/hr = 19.2 mg/hr. Finally, determine the mL/hr rate by using the concentration provided: 19.2 mg/hr / 800 mg in 250 mL = 6 mL/hr. Therefore, the correct answer is 6 mL/hr. Choice B, 8 mL/hr, is incorrect as it does not reflect the accurate calculation based on the weight and drug concentration. Choices C and D, 12 mL/hr and 16 mL/hr, are also incorrect as they do not align with the correct calculation of the infusion rate for dopamine hydrochloride based on the client's weight and the medication concentration.

2. A nurse is preparing to administer potassium chloride IV to a client who has hypokalemia. Which of the following actions should the nurse take?

• A. Give the medication as a bolus over 10 minutes.
• B. Dilute the medication before administration.
• C. Infuse the medication at a rate of 10 mEq/hr.
• D. Administer the medication undiluted.

Correct answer: C

Rationale: The correct action the nurse should take when administering potassium chloride IV to a client with hypokalemia is to infuse the medication at a rate of 10 mEq/hr. This slow infusion rate is crucial to prevent the development of hyperkalemia, a potentially dangerous condition. Option A is incorrect because giving the medication as a bolus over 10 minutes can lead to adverse effects. Option B is incorrect as potassium chloride does not necessarily need to be diluted before administration in this scenario. Option D is incorrect as administering the medication undiluted can also increase the risk of hyperkalemia.

3. A nurse is planning care for a client who has a nasogastric tube for enteral feedings. Which of the following interventions should the nurse include to prevent aspiration?

• A. Flush the tube with 30 mL of sterile water before each feeding.
• B. Check for gastric residuals every 4 hours.
• C. Elevate the head of the bed to 45 degrees during feedings.
• D. Place the client in the left lateral position during feedings.

Correct answer: C

Rationale: Elevating the head of the bed to 45 degrees during feedings is the correct intervention to prevent aspiration in clients with a nasogastric tube. This position helps reduce the risk of regurgitation and subsequent aspiration of stomach contents into the lungs. Flushing the tube with water before feedings (Choice A) is not necessary for preventing aspiration. Checking for gastric residuals (Choice B) helps monitor feeding tolerance but does not directly prevent aspiration. Placing the client in the left lateral position (Choice D) is not specifically indicated for preventing aspiration in a client with a nasogastric tube.

4. What is the appropriate nursing intervention for a patient experiencing a suspected stroke?

• A. Administer thrombolytics
• B. Perform a neurological assessment
• C. Perform a CT scan
• D. Administer oxygen

Correct answer: B

Rationale: Performing a neurological assessment is the appropriate nursing intervention for a patient experiencing a suspected stroke. This assessment helps determine the severity of the stroke, identify potential deficits, and guide further interventions. Administering thrombolytics (Choice A) should only be done after a CT scan to confirm the type of stroke and rule out hemorrhagic stroke. Performing a CT scan (Choice C) is important but is typically done after stabilizing the patient. Administering oxygen (Choice D) is essential to maintain adequate oxygenation, but performing a neurological assessment takes precedence in the immediate management of a suspected stroke.

5. Which lab value should be monitored in patients receiving furosemide?

• A. Monitor potassium levels
• B. Monitor sodium levels
• C. Monitor calcium levels
• D. Monitor glucose levels

Correct answer: A

Rationale: The correct answer is to monitor potassium levels in patients receiving furosemide. Furosemide is a loop diuretic that can lead to potassium loss in the urine, potentially causing hypokalemia. Monitoring potassium levels is crucial to prevent complications associated with low potassium levels, such as cardiac arrhythmias. Monitoring sodium levels (choice B) is not typically necessary with furosemide use, as it primarily affects potassium levels. Calcium levels (choice C) and glucose levels (choice D) are not directly impacted by furosemide and require monitoring for other conditions or medications.
