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 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.
A nurse is providing teaching to a newly licensed nurse about caring for a client who has a prescription for gemfibrozil. The nurse should instruct the newly licensed nurse to monitor which of the following laboratory tests?
- A. Platelet count
- B. Electrolyte levels
- C. Thyroid function
- D. Liver function
Correct Answer: D
Rationale: The correct answer is D: Liver function. Gemfibrozil can lead to hepatotoxicity, making it crucial to monitor liver function tests. Monitoring platelet count (choice A) is not specifically indicated for gemfibrozil. Electrolyte levels (choice B) and thyroid function (choice C) are not directly affected by gemfibrozil, so they are not the primary laboratory tests to monitor in this case.
A nurse is providing teaching to a client who has a urinary tract infection and new prescriptions for phenazopyridine and ciprofloxacin. Which of the following statements by the client indicates the need for further teaching?
- A. If the phenazopyridine upsets my stomach, I can take it with meals.
- B. The phenazopyridine will relieve my discomfort, but the ciprofloxacin will get rid of the infection.
- C. I need to drink 2 liters of fluid per day while I am taking the ciprofloxacin.
- D. I should notify my provider immediately if my urine turns an orange color.
Correct Answer: D
Rationale: Phenazopyridine can turn the urine orange, which is a normal side effect and not a cause for alarm. The client's statement about notifying the provider immediately if their urine turns orange indicates a need for further teaching because it shows a misunderstanding of the medication's side effects. Choices A, B, and C demonstrate a good understanding of the prescribed medications and their effects, indicating the client has grasped the teaching provided on those aspects.
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.
