A nurse is preparing to administer prochlorperazine 2.5 mg IV. Available is prochlorperazine injection 5 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth)
- A. 0.5 mL
- B. 0.005 mL
- C. 0.05 mL
- D. 5 mL
Correct Answer: A
Rationale: To calculate the mL needed, set up a proportion: 5 mg / 1 mL = 2.5 mg / X mL. Cross multiply to find X: 5 * X = 2.5 * 1, X = 2.5 / 5 = 0.5 mL. Therefore, the nurse should administer 0.5 mL. Choice B, 0.005 mL, is incorrect as it doesn't match the calculated result. Choice C, 0.05 mL, is incorrect as it is ten times the correct value. Choice D, 5 mL, is incorrect as it represents the total volume of the entire vial, not the amount needed for the specific dose.

A nurse is preparing to administer iron dextran IV to a client. Which of the following actions should the nurse plan to take?
- A. Administer a small test dose before giving the full dose
- B. Infuse the medication over 30 seconds
- C. Monitor client closely for hypertension
- D. Administer cyanocobalamin as an antidote if toxicity occurs
Correct Answer: A
Rationale: The correct action the nurse should plan to take when preparing to administer iron dextran IV is to administer a small test dose before giving the full dose. This is done to assess for any allergic reactions that the client may have to the medication. Choice B is incorrect because iron dextran should be infused slowly over a longer period, typically over 1-2 hours to reduce the risk of adverse reactions. Choice C is incorrect because iron dextran administration is more commonly associated with hypotension rather than hypertension. Choice D is incorrect because cyanocobalamin is not used as an antidote for iron dextran toxicity; instead, treatment for iron toxicity may involve supportive care, chelation therapy, or in severe cases, iron antidotes like deferoxamine.
A nurse is preparing to administer ampicillin 500 mg in 50 ml of dextrose 5% in water (D5W) to infuse over 15 min. The drop factor of the manual IV tubing is 10 gtt/mL. How many gtt/min should the nurse set the manual IV infusion to deliver? (Round to the nearest whole number)
- A. 33 gtt/min
- B. 66 gtt/min
- C. 10 gtt/min
- D. 14 gtt/min
Correct Answer: A
Rationale: To calculate the IV flow rate, you multiply the drop factor (10 gtt/mL) by the volume to be infused per minute (50 mL / 15 min). This gives you 10 gtt/mL 50 mL / 15 min = 33.33. Rounding to the nearest whole number, the nurse should set the manual IV infusion to deliver 33 gtt/min. Choice B (66 gtt/min) is incorrect as it is the result of doubling the correct answer. Choice C (10 gtt/min) is incorrect as it only considers the drop factor without accounting for the volume to be infused. Choice D (14 gtt/min) is incorrect as it miscalculates the infusion rate based on the given information.
A nurse on a medical unit is preparing to administer alendronate 40 mg PO for an older adult client who has Paget's disease of the bone. Which of the following actions should be the nurse's priority?
- A. Administer the medication to the client before breakfast in the morning.
- B. Assist the client to a chair before administering the medication.
- C. Give the medication to the client with water rather than milk.
- D. Educate the client on how to take the medication at home.
Correct Answer: A
Rationale: The correct answer is to administer the medication to the client before breakfast in the morning. Alendronate should be taken on an empty stomach before breakfast to ensure optimal absorption. Choice B is incorrect because assisting the client to a chair is not directly related to the administration of alendronate. Choice C is incorrect as there is no specific requirement to avoid taking alendronate with milk. Choice D is also incorrect as the priority at this moment is the correct administration of the medication in the hospital setting.
A nurse is providing teaching to a client who has cirrhosis and a new prescription for lactulose. The nurse should instruct the client that lactulose has which of the following therapeutic effects?
- A. Increases blood pressure
- B. Prevents esophageal bleeding
- C. Decreases heart rate
- D. Reduces ammonia levels
Correct Answer: D
Rationale: The correct answer is D: Reduces ammonia levels. Lactulose is used to reduce blood ammonia levels in clients with hepatic encephalopathy. Options A, B, and C are incorrect because lactulose does not have the therapeutic effect of increasing blood pressure, preventing esophageal bleeding, or decreasing heart rate.
A nurse is caring for a client who has a prescription for chlorothiazide to treat hypertension. The nurse should plan to monitor the client for which of the following adverse effects?
- A. Thrombophlebitis
- B. Hyperactive reflexes
- C. Muscle weakness
- D. Hypoglycemia
Correct Answer: C
Rationale: The correct answer is C: Muscle weakness. Chlorothiazide, a thiazide diuretic, can lead to hypokalemia, which can cause muscle weakness. Thrombophlebitis (choice A) is not typically associated with chlorothiazide use. Hyperactive reflexes (choice B) and hypoglycemia (choice D) are also not commonly linked to this medication. Therefore, monitoring for muscle weakness is crucial when a client is prescribed chlorothiazide.
