1. 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.

2. When administering subcutaneous epinephrine for a client experiencing anaphylaxis, what adverse effect should the nurse monitor for?

• A. Hypotension
• B. Hyperthermia
• C. Hypoglycemia
• D. Tachycardia

Correct answer: D

Rationale: The correct adverse effect to monitor for when administering subcutaneous epinephrine for anaphylaxis is tachycardia. Epinephrine stimulates adrenergic receptors, leading to an increased heart rate (tachycardia). Hypotension (Choice A) is less likely due to the vasoconstrictive effects of epinephrine. Hyperthermia (Choice B) and hypoglycemia (Choice C) are not commonly associated with epinephrine administration for anaphylaxis.

3. 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.

4. A nurse is preparing a discharge teaching plan for a client who is to begin long-term oral prednisone for asthma. Which of the following instructions should the nurse include in the plan?

• A. Stop taking the medication if a rash occurs.
• B. Take the medication on an empty stomach to enhance absorption.
• C. Schedule the medication on alternate days to decrease adverse effects.
• D. Treat shortness of breath with an extra dose of the medication.

Correct answer: C

Rationale: When initiating long-term oral prednisone therapy for asthma, it is essential to schedule the medication on alternate days. This approach helps reduce the risk of adverse effects commonly associated with corticosteroid use. Choice A is incorrect because abrupt discontinuation of prednisone can lead to adrenal insufficiency. Choice B is incorrect as prednisone should be taken with food to minimize gastrointestinal side effects. Choice D is incorrect because using an extra dose of prednisone to treat shortness of breath is not appropriate and can lead to overdosing.

5. A nurse is preparing to administer amoxicillin 250 mg liquid suspension PO every 8 hr to an older adult client. The amount available is amoxicillin 50 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest whole number)

• A. 5 mL
• B. 6 mL
• C. 4 mL
• D. 7 mL

Correct answer: A

Rationale: To calculate the amount of amoxicillin in mL needed per dose, we can use the formula: 50 mg/mL = 250 mg / X mL. Cross multiply to solve for X: 50X = 250. Divide both sides by 50 to find X, which equals 5 mL per dose. Therefore, the nurse should administer 5 mL of amoxicillin per dose. Choice B, 6 mL, is incorrect as it does not match the calculated result. Choice C, 4 mL, is incorrect as it is too low based on the calculation. Choice D, 7 mL, is incorrect as it is too high based on the calculation.
