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?
- A. 0.2 mL
- B. 0.5 mL
- C. 1.0 mL
- D. 1.5 mL
Correct Answer: B
Rationale: To determine the volume of prochlorperazine to administer, divide the prescribed dose (2.5 mg) by the concentration of the medication (5 mg/mL). This calculation results in 0.5 mL. Therefore, the nurse should administer 0.5 mL to deliver the correct dose. Choice A (0.2 mL) is incorrect as it miscalculates the dosage. Choices C (1.0 mL) and D (1.5 mL) are also incorrect as they do not accurately reflect the calculated volume needed for the dose.

A nurse is teaching a newly licensed nurse about contraindications to ceftriaxone. The nurse should include a severe allergy to which of the following medications as a contraindication to ceftriaxone?
- A. Gentamicin
- B. Clindamycin
- C. Piperacillin
- D. Sulfamethoxazole-trimethoprim
Correct Answer: C
Rationale: Ceftriaxone is a cephalosporin, and individuals with a penicillin allergy (such as Piperacillin) may have cross-sensitivity, making it contraindicated. Gentamicin (Choice A) belongs to the aminoglycoside class, not related to cephalosporins. Clindamycin (Choice B) is a lincosamide antibiotic and is not typically associated with cross-allergies to cephalosporins. Sulfamethoxazole-trimethoprim (Choice D) is a sulfonamide antibiotic, also not directly related to ceftriaxone.
A nurse is caring for a client who has congestive heart failure and is taking digoxin. The client reports nausea and refuses to eat breakfast. Which of the following actions should the nurse take first?
- A. Encourage the client to eat the toast on the breakfast tray
- B. Administer an antiemetic
- C. Inform the client's provider
- D. Check the client's apical pulse
Correct Answer: D
Rationale: The correct answer is to check the client's apical pulse first. Nausea can be a sign of digoxin toxicity, and assessing the client's heart rate is crucial in this situation. Administering an antiemetic or encouraging the client to eat should come after ensuring the client's safety. While informing the provider is important, the immediate concern is to assess for potential digoxin toxicity by checking the client's apical pulse.
A client at 28 weeks of gestation is experiencing preterm labor. Which of the following medications should the nurse plan to administer?
- A. Oxytocin
- B. Nifedipine
- C. Dinoprostone
- D. Misoprostol
Correct Answer: B
Rationale: Nifedipine is the correct choice in this scenario. It is a calcium channel blocker that helps suppress uterine contractions and halt preterm labor. Nifedipine is commonly used to manage preterm labor in pregnant women by relaxing the smooth muscle of the uterus. Oxytocin (Choice A) is used to induce or augment labor, not to inhibit contractions. Dinoprostone (Choice C) and Misoprostol (Choice D) are prostaglandins used for cervical ripening and induction of labor, not for stopping preterm labor.
A nurse is planning to administer diltiazem via IV bolus to a client who has atrial fibrillation. Which of the following findings is a contraindication to the administration of diltiazem?
- A. Hypotension
- B. Tachycardia
- C. Decreased level of consciousness
- D. History of diuretic use
Correct Answer: A
Rationale: The correct answer is A: Hypotension. Diltiazem, a calcium channel blocker, can cause hypotension. Administering diltiazem to a client with hypotension can further lower their blood pressure, leading to adverse effects like dizziness and syncope. Tachycardia (Choice B) is actually a common indication for diltiazem use, as it helps slow down the heart rate in conditions like atrial fibrillation. Decreased level of consciousness (Choice C) may require evaluation but is not a direct contraindication to diltiazem administration. History of diuretic use (Choice D) is not a contraindication to diltiazem, as the two medications can often be safely used together.
