The nurse is teaching a client who is prescribed acetaminophen for control of osteoarthritic joint pain. What statement by the client indicates a need for further teaching?
I won’t take more than 5000 mg of this drug each day.
I’ll follow up to get my lab tests done to check my liver.
I’ll check drugs that I take for acetaminophen in them.
I can use topical patches and creams to help relieve pain.
The Correct Answer is A
Choice A reason: The maximum daily dose of acetaminophen for adults is typically 4000 mg to avoid hepatotoxicity. A statement indicating 5000 mg suggests a misunderstanding, as exceeding 4000 mg increases the risk of liver damage due to the accumulation of toxic metabolites like N-acetyl-p-benzoquinone imine, which depletes glutathione.
Choice B reason: Regular liver function tests are recommended for clients on long-term acetaminophen to monitor for hepatotoxicity, as the drug is metabolized by the liver. This statement shows correct understanding, as it acknowledges the need to assess liver enzymes like ALT and AST for potential damage.
Choice C reason: Checking other medications for acetaminophen content is crucial to prevent unintentional overdose, which can lead to acute liver failure. This statement reflects proper understanding, as combination drugs (e.g., cold remedies) often contain acetaminophen, contributing to cumulative toxicity if not monitored.
Choice D reason: Using topical patches or creams for osteoarthritis pain is a valid adjunctive therapy. These deliver localized relief (e.g., NSAIDs or capsaicin) without systemic effects, complementing acetaminophen’s action. This statement indicates correct understanding of multimodal pain management strategies.

Correct Answer is B
Explanation
Choice A reason: Controlled hypertension, when managed with medications, poses minimal risk to postoperative healing. Stable blood pressure ensures adequate tissue perfusion, supporting wound healing and recovery. It is not a significant risk factor compared to other conditions that directly impair tissue repair.
Choice B reason: Obesity significantly increases the risk of impaired postoperative healing due to increased mechanical stress on the surgical site, reduced tissue oxygenation, and higher rates of infection. Adipose tissue has poor vascularity, delaying wound healing, and obesity is associated with comorbidities like diabetes, further complicating recovery.
Choice C reason: Osteoarthritis, the primary indication for knee arthroplasty, does not directly impair postoperative healing. It affects joint cartilage but not the body’s wound healing mechanisms, such as collagen synthesis or immune response, making it a less significant risk factor.
Choice D reason: Mild osteopenia, a precursor to osteoporosis, indicates slightly reduced bone density but does not significantly affect soft tissue healing or surgical outcomes. It may influence implant stability long-term but is less critical for immediate postoperative healing compared to obesity.
Correct Answer is D
Explanation
Choice A reason: Drinking 2 liters of water daily supports general health but is not specific to phenytoin therapy. It does not prevent complications like gingival hyperplasia or hepatotoxicity, which are more directly related to phenytoin’s pharmacological effects and monitoring needs.
Choice B reason: Phenytoin does not eliminate seizure auras, which are sensory warnings due to focal cortical activity. It stabilizes neuronal membranes via sodium channel blockade, reducing seizure frequency but not preventing prodromal symptoms like auras.
Choice C reason: Not driving is appropriate, as phenytoin can cause dizziness or ataxia, impairing motor coordination. However, this is a safety precaution, not the most comprehensive indicator of understanding the need for long-term adherence to prevent seizure recurrence.
Choice D reason: Continuing phenytoin even after seizures stop is critical, as abrupt cessation can cause rebound seizures due to unopposed neuronal excitability. This reflects understanding of lifelong therapy needs for status epilepticus to maintain seizure control and prevent recurrence.
