A nurse is monitoring a client who is 36 hr postoperative following a left knee arthroscopy. Which of the following findings should the nurse report to the provider?

A. Prednisolone: Corticosteroids like prednisolone are not contraindicated with fluoxetine. Although concurrent use may slightly increase the risk of gastrointestinal irritation or affect blood glucose levels, there is no major drug interaction that prevents their coadministration.

B. Lispro: Lispro is a rapid-acting insulin used for diabetes management. Fluoxetine does not directly contraindicate insulin use, though it may slightly affect glycemic control in some clients. Close monitoring of blood glucose is recommended, but the combination is generally safe.

C. Calcitonin: Calcitonin, used for conditions like osteoporosis, does not have significant interactions with fluoxetine. There is no contraindication for concurrent use, and standard monitoring is sufficient.

D. Phenelzine: Phenelzine is a monoamine oxidase inhibitor (MAOI). Combining MAOIs with fluoxetine, a selective serotonin reuptake inhibitor (SSRI), can precipitate serotonin syndrome, a potentially life-threatening condition characterized by confusion, hyperthermia, autonomic instability, and neuromuscular abnormalities. Concurrent use is strictly contraindicated.

A. Terbutaline: Terbutaline is a beta-agonist used to relax the uterus in cases of preterm labor or to manage uterine hyperstimulation, which would worsen postpartum bleeding. It is contraindicated in postpartum hemorrhage because it inhibits uterine contractions needed to control bleeding.

B. Methylergonovine: Methylergonovine is a uterotonic medication that stimulates sustained uterine contractions, promoting uterine tone and helping to control postpartum hemorrhage. It is used when hemorrhage results from uterine atony and is contraindicated in clients with hypertension or preeclampsia due to vasoconstrictive effects.

C. Magnesium sulfate: Magnesium sulfate is used primarily for seizure prophylaxis in preeclampsia and for tocolysis in preterm labor. It relaxes smooth muscle, including the uterus, which would exacerbate postpartum bleeding rather than treat it.

D. Nifedipine: Nifedipine is a calcium channel blocker used as a tocolytic to inhibit preterm labor. It decreases uterine contractions and is therefore inappropriate for managing postpartum hemorrhage, as it would reduce uterine tone and increase bleeding risk.
