Correct Answer: C

Rationale: The correct answer is C: Neutropenia. Paclitaxel commonly causes neutropenia due to bone marrow suppression. It is essential for clients receiving this medication to monitor for signs of neutropenia, such as fever, chills, and increased susceptibility to infections, as it can increase the risk of serious complications.

Correct Answer: A

Rationale: Neostigmine is a cholinesterase inhibitor commonly used to reverse the effects of nondepolarizing neuromuscular blockers by increasing acetylcholine levels at the neuromuscular junction, thereby helping to restore muscle strength. Naloxone is an opioid antagonist used to reverse opioid effects, not neuromuscular blockade. Dantrolene is a skeletal muscle relaxant used to treat malignant hyperthermia or neuroleptic malignant syndrome, not to reverse neuromuscular blockade. Vecuronium is a nondepolarizing neuromuscular blocking agent, like the one the client received, and is not used to reverse its effects.

Correct Answer: A

Rationale: Performing immediate gastric lavage is the appropriate action for a client with severe lithium toxicity, indicated by a plasma lithium level of 2.1 mEq/L. Gastric lavage can help reduce the client's lithium level by removing the unabsorbed drug from the stomach.

Rationale: The correct instruction to include in the discharge teaching for a client prescribed Metronidazole is to avoid drinking alcohol while taking this medication. Drinking alcohol with Metronidazole can result in a disulfiram-like reaction, leading to symptoms such as nausea, vomiting, and flushing. Therefore, it is crucial for the client to abstain from alcohol consumption during the course of treatment with Metronidazole.
