A nurse is teaching a client who has a new prescription for warfarin to treat atrial fibrillation. Which of the following statements by the client indicates an understanding of the teaching?
"I will take a missed dose as soon as I remember it."
"I will avoid foods that are high in vitamin E."
"I can take ginseng supplements to improve my memory."
"I should expect to have bleeding gums while taking this medication”
The Correct Answer is A
Rationale:
A. "I will take a missed dose as soon as I remember it." This reflects correct understanding. Warfarin should be taken at the same time daily, but if a dose is missed, the client should take it as soon as possible on the same day. Double dosing should be avoided.
B. "I will avoid foods that are high in vitamin E." Clients on warfarin are typically advised to monitor vitamin K intake, not vitamin E, because vitamin K can counteract the effects of warfarin. Vitamin E in high doses can increase bleeding risk, but it's not the primary concern.
C. "I can take ginseng supplements to improve my memory." Ginseng can interfere with warfarin’s effectiveness and may increase the risk of bleeding or decrease anticoagulant effect, making it unsafe to take without provider consultation.
D. "I should expect to have bleeding gums while taking this medication.” Bleeding gums may indicate excessive anticoagulation and potential bleeding risk. This is a warning sign, not an expected side effect, and should be reported immediately.

Correct Answer is B
Explanation
Rationale:
A. Gabapentin: Gabapentin is an anticonvulsant often used to treat neuropathic pain, not minor inflammatory pain. It is not classified as a nonsteroidal anti-inflammatory drug (NSAID) and is inappropriate for treating pressure ulcer discomfort without nerve involvement.
B. Naproxen: Naproxen is an NSAID that provides effective relief for mild to moderate pain and inflammation. It works by inhibiting prostaglandin synthesis, making it suitable for managing the minor pain associated with pressure ulcers.
C. Dantrolene: Dantrolene is a muscle relaxant used to treat muscle spasticity or malignant hyperthermia. It does not have anti-inflammatory properties and is not indicated for relieving minor inflammatory or nociceptive pain.
D. Baclofen: Baclofen is a central nervous system muscle relaxant used to manage spasticity. It is not an NSAID and lacks the anti-inflammatory effect needed to address the minor pain linked to tissue inflammation in pressure ulcers.
Correct Answer is D
Explanation
Rationale:
A. Jugular neck vein distention: Jugular venous distention is a hallmark sign of right-sided heart failure, caused by systemic venous congestion. It is not typically seen in isolated left-sided heart failure.
B. Dependent edema: Dependent or peripheral edema is another finding associated with right-sided heart failure, resulting from fluid accumulation in the lower extremities due to poor venous return.
C. Distended abdomen: A distended abdomen, often from ascites, is more indicative of right-sided heart failure due to hepatic and portal vein congestion. It is not a classic symptom of left-sided heart failure.
D. Pink-tinged sputum: Pink, frothy sputum is a key finding in left-sided heart failure, particularly when pulmonary edema develops. It results from fluid backing up into the lungs due to impaired left ventricular function, leading to pulmonary capillary pressure increases and fluid leakage into alveoli.
