1. A client has a new prescription for Furosemide. Which of the following adverse effects should the nurse monitor?
- A. Hyperkalemia
- B. Hyponatremia
- C. Hypernatremia
- D. Hypercalcemia
Correct answer: B
Rationale: The correct answer is B: Hyponatremia. Furosemide, a diuretic, commonly causes hyponatremia (low sodium levels) as it increases the excretion of sodium. The nurse needs to monitor the client for signs of hyponatremia, such as confusion, weakness, and muscle cramps, by checking electrolyte levels regularly. Choices A, C, and D are incorrect because hyperkalemia (choice A), hypernatremia (choice C), and hypercalcemia (choice D) are not typically associated with Furosemide use.
2. A healthcare professional is preparing to administer dextrose 5% in water (D5W) 750 mL IV to infuse over 6 hr. How many mL/hr should the IV pump be set to deliver?
- A. 125 mL/hr
- B. 100 mL/hr
- C. 150 mL/hr
- D. 200 mL/hr
Correct answer: A
Rationale: To calculate the flow rate, divide the total volume by the total time: 750 mL / 6 hr = 125 mL/hr. Therefore, the IV pump should be set to deliver 125 mL/hr to infuse D5W 750 mL over 6 hours. Choice B (100 mL/hr) is incorrect because it does not accurately divide the total volume by the total time. Choice C (150 mL/hr) and Choice D (200 mL/hr) are incorrect as they are not the correct flow rates needed to infuse the D5W solution over the specified time period.
3. A client with cirrhosis is about to receive a dose of lactulose. The client questions the need for the medication, stating they are not constipated. The nurse should explain that lactulose is used in cirrhosis to reduce levels of which component in the bloodstream?
- A. Glucose
- B. Ammonia
- C. Potassium
- D. Bicarbonate
Correct answer: B
Rationale: Lactulose is administered to clients with cirrhosis to lower blood ammonia levels, thus aiding in the prevention of hepatic encephalopathy. Elevated ammonia levels in cirrhosis can lead to cognitive impairment and hepatic encephalopathy. Therefore, the correct answer is B (Ammonia). Glucose (Choice A) is not the component targeted by lactulose in cirrhosis. Potassium (Choice C) and Bicarbonate (Choice D) are not directly affected by lactulose administration in cirrhosis.
4. What are the actions of the drug metformin?
- A. Decreases hepatic glucose production and intestinal glucose absorption
- B. Increases sensitivity to insulin
- C. Short-term sedation
- D. Both A and B
Correct answer: D
Rationale: Metformin has dual actions by decreasing hepatic glucose production and intestinal glucose absorption, which helps in reducing blood glucose levels. Additionally, it increases sensitivity to insulin, aiding in its proper utilization within the body. Choice A is correct as metformin acts by decreasing hepatic glucose production and intestinal glucose absorption. Choice B is also correct as metformin increases sensitivity to insulin. Choice C, short-term sedation, is incorrect as metformin is not known for causing sedation. Therefore, the correct answer is D because metformin performs both of these actions.
5. A client has been prescribed an anticoagulant for atrial fibrillation. Which of the following instructions should the nurse include?
- A. Take the medication with food to prevent nausea.
- B. Avoid activities that may cause injury.
- C. Monitor your heart rate daily before taking the medication.
- D. Avoid alcohol while taking this medication.
Correct answer: B
Rationale: The correct instruction for a client prescribed an anticoagulant for atrial fibrillation is to avoid activities that may cause injury. Anticoagulants increase the risk of bleeding, so it is important to prevent situations that could lead to injury or trauma. Choice A is incorrect because anticoagulants are not typically affected by food intake. Choice C is not necessary for all anticoagulant medications, and heart rate monitoring is more relevant for other conditions. Choice D is not directly related to the action of anticoagulants and is not a priority instruction for this medication.
