A nurse is reinforcing teaching with a client who has COPD and has been taking long-term high doses of prednisone. Which of the following instructions should the nurse include in the teaching?

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.

A. Lower the head of the client's bed. There is no need to lower the client’s head of the bed in response to receiving glipizide instead of guaifenesin. Glipizide is an oral antidiabetic medication used to lower blood glucose, while guaifenesin is an expectorant for respiratory conditions. Lowering the head of the bed does not address the potential effects of receiving the wrong medication.

B. Check the client for urinary retention. Glipizide does not cause urinary retention. Instead, it stimulates insulin release to lower blood sugar. If hypoglycemia occurs due to an unintentional dose of glipizide, symptoms such as sweating, dizziness, confusion, or tremors are more concerning than bladder dysfunction.

C. Offer the client a carbohydrate snack. Since glipizide lowers blood glucose levels, administering it instead of guaifenesin could result in hypoglycemia, particularly in a client who does not have diabetes. The nurse should monitor for signs of low blood sugar, such as shakiness, confusion, diaphoresis, and dizziness, and provide a fast-acting carbohydrate (e.g., juice, crackers, or glucose tablets) if symptoms develop.

D. Test the client’s deep-tendon reflexes. Glipizide does not affect neuromuscular function or deep-tendon reflexes. While severe hypoglycemia can cause altered mental status or seizures, routine reflex testing is not necessary for monitoring the effects of an incorrect glipizide administration.
