1. What is the therapeutic action of Phenytoin?

Correct answer: B

Rationale: Phenytoin is primarily used as an anticonvulsant to prevent and control seizures. It works by stabilizing electrical activity in the brain, making it effective in managing conditions like epilepsy. Antidiabetic medications are used to regulate blood sugar levels, mood stabilizers help manage mood disorders, and antianxiety agents are used to reduce anxiety symptoms, none of which are the primary therapeutic action of Phenytoin.

2. When teaching parents about a child newly prescribed Desipramine, the nurse should instruct them that which of the following adverse effects is the priority to report to the provider?

Correct answer: B

Rationale: The priority adverse effect to report when a child is prescribed Desipramine is suicidal thoughts. Desipramine can increase the risk of suicidal thoughts and behaviors. It is crucial for parents to monitor the child for any signs of worsening depression or thoughts of self-harm and report them promptly to the healthcare provider to prevent any harm to the child. Options A, C, and D are potential side effects of Desipramine but are not as urgent or life-threatening as suicidal thoughts, which require immediate intervention to ensure the safety of the child.

3. What is the correct definition of drug absorption?

Correct answer: A

Rationale: The correct definition of drug absorption is the movement of a drug from the site of administration into various tissues of the body. It is the process by which a drug is taken up and enters the systemic circulation. Choice B describes the pharmacokinetics of drugs, including absorption, distribution, metabolism, and excretion, but it is not a specific definition of drug absorption. Choice C is unrelated to drug absorption, as it refers to over-the-counter drugs. Choice D is too vague and does not specifically address the process of drug absorption.

4. A client in the post-anesthesia recovery unit received a nondepolarizing neuromuscular blocking agent and has muscle weakness. The nurse should anticipate a prescription for which of the following medications?

Correct answer: A

Rationale: Neostigmine is a cholinesterase inhibitor commonly used to reverse the effects of nondepolarizing neuromuscular blockers, such as the one the client received. It works by inhibiting the breakdown of acetylcholine, thereby enhancing neuromuscular transmission and reversing muscle weakness caused by the neuromuscular blocking agent.

5. A healthcare professional is caring for a client who is receiving treatment with carboplatin. Which of the following findings should the healthcare professional monitor?

Correct answer: B

Rationale: The healthcare professional should monitor the client for ototoxicity when receiving carboplatin. Ototoxicity is a known serious adverse effect associated with this medication, characterized by damage to the inner ear structures leading to hearing loss or balance issues. Monitoring for hearing changes and balance problems is crucial to detect ototoxicity early and prevent further complications. Hyperglycemia, hypertension, and bradycardia are not typically associated with carboplatin therapy.
