Question

A nurse is assisting with the care of a client who is 24hr postoperative following a cesarean birth. Which of the following prescriptions should the nurse clarify with the charge nurse?

Answer 1

Correct Answers:

Ciprofloxacin 1000mg daily

Rationale :

🔴 Ciprofloxacin is a fluoroquinolone antibiotic, which is generally not recommended postpartum—especially for breastfeeding clients, due to potential risks including tendon rupture and cartilage damage in neonates.

🔴 A dose of 1000 mg daily is also considered high and unusual for routine post-cesarean prophylaxis.

🔴 Standard postpartum infection prevention typically involves first-line antibiotics like cefazolin or ampicillin, not ciprofloxacin.

🔴 Therefore, this prescription should be clarified immediately to ensure it's appropriate for the postpartum and lactating status.

Answer 3

Correct Answers:

The nurse should wait until the client has more than four contractions in 1 hr before administering terbutaline.

Rationale :

🟢 The prescription states terbutaline 0.25 mg subcutaneously every 4 hours PRN (as needed) for more than four uterine contractions per hour.

🟢 This means the nurse should monitor contraction frequency and only administer the medication if the client exceeds four contractions in one hour.

🟢 It is not a scheduled medication; rather, it is used reactively to suppress preterm labor contractions.

🟢 Administering terbutaline without the presence of excessive contractions could result in unnecessary side effects such as tachycardia, jitteriness, or pulmonary edema.

🟢 Once administered, it can be repeated no more frequently than every 4 hours, and only within a 24-hour total time frame.

Answer 5

Correct Answers:

2

Rationale :

🟢 The prescription is for 0.4 mg of methylergonovine to be given orally.

🟢 The tablets available are 200 mcg (micrograms) each.

🟢 First, convert 0.4 mg to micrograms:

0.4 mg×1000

400 mcg

🟢 Next, divide the required dose by the strength per tablet:

400 mcg/200 mcg/tablet

2 tablets

0.5

Rationale :

🟢 The prescribed dose is 10 mg of nalbuphine IM.

🟢 The available solution is 20 mg/mL,

🟢The nurse needs to calculate the volume that delivers 10 mg.

🟢 Use the formula:

Volume to administer=Desired dose/Concentration

10 mg/20 mg/mL

0.5 mL

75 mg/100 mg/mL

0.75 mL
