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 reviewing the laboratory results of a client who is receiving warfarin therapy for atrial fibrillation. Which of the following laboratory values should the nurse report to the provider?

• A. INR 1.8
• B. Hemoglobin 14 g/dL
• C. Platelets 175,000/mm³
• D. Potassium 3.8 mEq/L

Correct answer: A

Rationale: The correct answer is A. An INR of 1.8 is below the therapeutic range for a client receiving warfarin, indicating a potential risk of blood clots. This value should be reported to the provider for further evaluation and possible adjustment of the warfarin dosage. Choices B, C, and D are within normal ranges and do not directly relate to the effectiveness or safety of warfarin therapy in this scenario, making them less urgent to report.

3. A nurse is providing discharge teaching to a client who had a stroke. What instruction should the nurse provide?

• A. Avoid lifting more than 5 pounds.
• B. Perform range-of-motion exercises daily.
• C. Take medications at the same time every day.
• D. Monitor blood pressure daily.

Correct answer: C

Rationale: The correct answer is C: 'Take medications at the same time every day.' Consistency in medication administration is crucial for stroke recovery to maintain therapeutic drug levels in the body. Choice A, 'Avoid lifting more than 5 pounds,' though important to prevent strain, is not directly related to medication adherence. Choice B, 'Perform range-of-motion exercises daily,' is beneficial for overall recovery but is not specific to medication management. Choice D, 'Monitor blood pressure daily,' is important but does not address the key aspect of medication regimen adherence.

4. A healthcare provider is caring for a client who has been diagnosed with sepsis. Which of the following laboratory results indicates that the client is developing disseminated intravascular coagulation (DIC)?

• A. Elevated hemoglobin
• B. Elevated white blood cell count
• C. Decreased fibrinogen level
• D. Decreased platelet count

Correct answer: D

Rationale: The correct answer is D, decreased platelet count. In disseminated intravascular coagulation (DIC), there is widespread activation of clotting factors leading to the formation of multiple blood clots throughout the body, which can deplete platelets. A decreased platelet count is a hallmark of DIC. Elevated hemoglobin (choice A) and elevated white blood cell count (choice B) are not specific indicators of DIC. While fibrinogen levels (choice C) can be decreased in DIC due to consumption, a decreased platelet count is a more specific and early sign of DIC development.

5. A client has a new prescription for digoxin. Which of the following instructions should the nurse include?

• A. Take this medication with food to prevent nausea.
• B. Notify your provider if you experience visual disturbances.
• C. Take an antacid with this medication if indigestion occurs.
• D. Avoid taking this medication if your heart rate is less than 60/min.

Correct answer: B

Rationale: The correct instruction for a client taking digoxin is to notify their provider if they experience visual disturbances. Visual disturbances can be a sign of digoxin toxicity, and prompt notification to the healthcare provider is essential for timely intervention. Choice A is incorrect because digoxin should be taken on an empty stomach for better absorption. Choice C is incorrect because antacids can interfere with the absorption of digoxin. Choice D is incorrect because a heart rate less than 60/min is not a sole reason to avoid taking digoxin; rather, it is important to monitor the heart rate and consult with the healthcare provider if there are concerns.
