A nurse is assisting in the plan of care for a client who has a suspected myocardial infarction. Which of the following medications should the nurse plan to administer first?

Choice A : While vitamin K is essential for normal blood clotting, warfarin works by blocking the action of vitamin K. Therefore, clients taking warfarin should maintain a consistent intake of vitamin K-rich foods to avoid fluctuations in their response to the medication. Inconsistent vitamin K intake can affect the effectiveness of warfarin. The nurse should educate the client to consume a consistent amount of vitamin K-containing foods rather than emphasizing "lots" of vitamin K.

Choice B : Warfarin is an anticoagulant that increases the risk of bleeding. Taking aspirin (another blood-thinning medication) along with warfarin can further enhance this risk. The nurse should emphasize that clients should avoid taking aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs) without consulting their healthcare provider while on warfarin therapy.

Choice C : Alcohol can interact with warfarin and increase the risk of bleeding. Clients should be advised to limit alcohol consumption while taking warfarin. The nurse should educate the client that alcohol intake should be moderate and consistent, rather than encouraging wine consumption.

Choice D :While it is essential to minimize the risk of cuts and bleeding, the use of an electric razor is not specific to warfarin therapy. Clients should be cautious with any sharp objects, including razors, to prevent bleeding. The nurse should provide general safety instructions for shaving, but this choice does not directly relate to warfarin effects.

Choice A reason : Hepatomegaly, or the enlargement of the liver, is a common finding in right-sided heart failure. This condition occurs because the heart does not pump blood effectively, leading to congestion and increased pressure in the venous system, including the hepatic veins. As a result, the liver becomes engorged with blood, causing it to enlarge. The normal liver span in adults is about 10-12 cm in the midclavicular line, and any measurement above this can indicate hepatomegaly.

Choice B reason : Orthopnea, which is shortness of breath while lying flat, is more commonly associated with left-sided heart failure. In right-sided heart failure, symptoms are more related to systemic congestion, such as swelling in the legs and abdomen, rather than pulmonary symptoms like orthopnea.

Choice C reason : Dyspnea, or difficulty breathing, can be a symptom of both left and right-sided heart failure. However, in the context of right-sided heart failure, dyspnea is usually due to the accumulation of fluid in the abdominal cavity (ascites) and the increased pressure in the abdominal veins, which can compress the diaphragm and make breathing difficult.

Choice D reason : Frothy sputum is typically not a symptom of right-sided heart failure. It is more indicative of pulmonary edema, which is associated with left-sided heart failure. In right-sided heart failure, the primary issues are related to the systemic circulation and venous congestion.
