1. When starting Alfuzosin for the treatment of Benign Prostatic Hyperplasia, a nurse is providing teaching to a client. The nurse should instruct the client that which of the following is an adverse effect of this medication?
- A. Bradycardia
- B. Edema
- C. Hypotension
- D. Tremor
Correct answer: C
Rationale: The correct adverse effect of Alfuzosin is hypotension. Alfuzosin relaxes muscle tone in veins, leading to decreased cardiac output and subsequent hypotension. Patients on this medication should be advised to change positions slowly to prevent a sudden drop in blood pressure. Choice A, Bradycardia, is not a common adverse effect of Alfuzosin. Choice B, Edema, is not typically associated with Alfuzosin use. Choice D, Tremor, is also not a common adverse effect of Alfuzosin.
2. A client has a new prescription for Furosemide. What instruction should be included by the nurse during discharge?
- A. Take the medication at bedtime.
- B. Increase intake of foods high in potassium.
- C. Avoid sun exposure.
- D. Limit fluid intake.
Correct answer: B
Rationale: The correct answer is to instruct the client to increase intake of foods high in potassium. Furosemide, a loop diuretic, can lead to potassium depletion. Increasing the intake of foods rich in potassium can help prevent hypokalemia, a potential side effect of Furosemide. Choice A is incorrect as Furosemide is usually recommended to be taken in the morning to avoid disrupting sleep with frequent urination. Choice C is irrelevant to the medication. Choice D is also incorrect as Furosemide is a diuretic and may require increased, not limited, fluid intake to prevent dehydration.
3. A client has a new prescription for Lovastatin. Which of the following instructions should be included?
- A. Take this medication on an empty stomach.
- B. Take this medication in the morning.
- C. Take this medication at bedtime.
- D. Increase your intake of potassium-rich foods.
Correct answer: C
Rationale: Lovastatin should be taken at bedtime because cholesterol production in the liver is highest at night, making the medication more effective in reducing cholesterol levels. By taking it at bedtime, the medication aligns with the body's natural rhythm of cholesterol synthesis, optimizing its therapeutic effects.
4. 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.
5. A client in a coronary care unit is being admitted after CPR post cardiac arrest. The client is receiving IV lidocaine at 2 mg/min. When the client asks the nurse why he is receiving that medication, the nurse should explain that it has which of the following actions?
- A. Prevents dysrhythmias
- B. Slows intestinal motility
- C. Dissolves blood clots
- D. Relieves pain
Correct answer: A
Rationale: Lidocaine is administered to prevent dysrhythmias by delaying conduction in the heart and reducing the automaticity of heart tissue. This action helps stabilize the heart's electrical activity and prevent life-threatening arrhythmias post-cardiac arrest. Choices B, C, and D are incorrect as lidocaine is not used for slowing intestinal motility, dissolving blood clots, or relieving pain in this context.
