A nurse is collecting data from a client who has gout and is taking allopurinol. Which of the following adverse effects should the nurse identify as the priority to report to the provider?

A. Diphenhydramine. Diphenhydramine is a first-generation antihistamine with anticholinergic properties that can increase the risk of central nervous system (CNS) depression when taken with haloperidol. Both drugs can cause sedation, confusion, and impaired coordination, increasing the risk of falls and other complications. Additionally, combining them can worsen extrapyramidal symptoms (EPS) or lead to anticholinergic toxicity, making it an unsafe combination.

B. Docusate sodium. Docusate sodium is a stool softener used to prevent constipation. Haloperidol can cause constipation as a side effect due to its anticholinergic properties, so docusate sodium is safe and may even be beneficial in preventing bowel complications.

C. Ibuprofen. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) used for pain and inflammation. While it does not have a direct interaction with haloperidol, it should be used with caution in clients with a history of gastrointestinal issues or kidney disease. However, it does not pose a significant risk when taken alongside haloperidol.

D. Glucosamine. Glucosamine is a dietary supplement used to support joint health. It does not interact with haloperidol and does not have sedative or CNS effects. Clients taking haloperidol can safely use glucosamine if needed.

A. Breastfeeding. Ceftriaxone is generally considered safe during breastfeeding because only a small amount is excreted in breast milk. While monitoring for gastrointestinal disturbances or thrush in the infant is advised, breastfeeding is not a contraindication for ceftriaxone use.

B. Client allergy. The client has a penicillin allergy, which raises concerns about cross-reactivity with cephalosporins, including ceftriaxone. Although the cross-reactivity rate is low, clients with a history of severe allergic reactions (e.g., anaphylaxis, angioedema, or urticaria) to penicillin should avoid cephalosporins. The nurse should clarify the nature of the penicillin allergy before administering ceftriaxone.

C. Gentamycin prescription. Ceftriaxone and gentamicin are both nephrotoxic, and using them together increases the risk of kidney damage. The client should be monitored for renal function impairment, and alternative antibiotic therapy may be considered if necessary. The nurse should discuss this potential drug interaction with the provider before administration.

D. Hematocrit. The client’s hematocrit (32%) is low but does not require withholding ceftriaxone. A slightly decreased hematocrit is expected postpartum, especially in cases of infection or recent delivery. Ceftriaxone is not known to cause significant hematologic suppression that would make this a contraindication.

E. Hemoglobin. The client’s hemoglobin (9 g/dL) is lower than normal, likely due to postpartum blood loss or infection-related inflammation. However, ceftriaxone does not directly affect hemoglobin levels, so this is not a reason to withhold the medication.
