Incorrect. Metformin does not cause hypoglycemia, as it does not stimulate insulin secretion. It lowers blood glucose levels by decreasing hepatic glucose production and increasing insulin sensitivity.

Incorrect. Metformin absorption is not affected by food intake. The medication can be taken with or without food, but taking it with meals can help reduce gastrointestinal side effects.

Incorrect. Metformin effectiveness is not influenced by food intake. The medication works by improving glucose metabolism and insulin action.

Incorrect. Extrapyramidal symptoms (EPS), such as dystonia, akathisia, and tardive dyskinesia, are caused by dopamine antagonists, such as haloperidol. However, these symptoms are not related to the combination of medications that the client is taking.

Incorrect. Lithium toxicity is a condition that occurs when lithium levels exceed the therapeutic range of 0.6 to 1.2 mEq/L. It is caused by factors that affect lithium excretion, such as dehydration, renal impairment, drug interactions, and overdose. None of the other medications that the client is taking interact with lithium or affect its excretion.

Incorrect. Morphine sulfate does not need to be diluted in normal saline before administration. Diluting the medication can reduce its potency and effectiveness.

Incorrect. Heparin is not indicated for flushing the IV line before and after administration of morphine sulfate. Heparin is an anticoagulant that can increase the risk of bleeding. The IV line should be flushed with normal saline or sterile water to prevent medication incompatibility and ensure complete delivery of the medication.

Incorrect. The nurse should monitor the client's respiratory rate more frequently than every 15 minutes, as morphine sulfate can cause respiratory depression. The nurse should monitor the client's respiratory rate before, during, and after administration of the medication, and at least every 5 minutes until the client's pain is relieved.

Incorrect. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that can be used safely with phenytoin. However, the nurse should advise the client to monitor for signs of bleeding, such as bruising, petechiae, and hematuria, as NSAIDs can inhibit platelet aggregation and increase the risk of bleeding.

Incorrect. Diphenhydramine is an antihistamine that can be used safely with phenytoin. However, the nurse should advise the client to avoid driving or operating machinery while taking diphenhydramine, as it can cause drowsiness and impair mental alertness.

Incorrect. Diarrhea is a common side effect of amoxicillin, but it is not a sign of an allergic reaction. The nurse should advise the client to drink plenty of fluids and eat foods that are high in fiber to prevent dehydration and constipation. The nurse should also instruct the client to report severe or bloody diarrhea, as it may indicate a serious condition called pseudomembranous colitis.
