A nurse is teaching the guardian of a 1-month-old infant about infant safety. Which of the following information should the nurse include in the teaching?

A. Diphenhydramine. Urticaria (hives) is a common allergic reaction often caused by medications like antibiotics. Diphenhydramine, an antihistamine, is used to treat allergic reactions by blocking histamine receptors, reducing itching, swelling, and rash.
B. Hydralazine. This is an antihypertensive medication used to treat high blood pressure, not allergic reactions. It has no effect on histamine or allergic symptoms.
C. Naloxone. Naloxone is an opioid antagonist used to reverse opioid overdose. It does not treat allergic reactions like urticaria unless the cause is opioid-induced (which is not indicated here).
D. Protamine. Protamine is used to reverse the effects of heparin. It has no role in treating allergic reactions to antibiotics.

A. "I will hang a new bag of TPN and IV tubing every 24 hours." This is the correct action. TPN solutions are high in glucose and lipids, which create an ideal environment for bacterial growth. Changing the bag and tubing every 24 hours reduces the risk of infection and sepsis, especially in clients with central lines.
B. "I will obtain the client's weight every other day." Weight should be monitored daily in clients receiving TPN to assess for fluid status, nutritional progress, and potential complications like fluid overload or retention.
C. "I will monitor the client's blood glucose level every 8 hours." Clients receiving TPN require more frequent glucose monitoring, typically every 4 to 6 hours, especially when therapy is initiated, due to the high dextrose content that can cause hyperglycemia.
D. “I will increase the rate of the TPN infusion to ensure the correct amount is given." TPN infusion rates should never be adjusted independently by a nurse. Changes must be made only with a provider’s order, as improper rate adjustments can lead to electrolyte imbalances, hyperglycemia, or fluid overload.
