The nurse would be most concerned about a prescription for a lipid emulsion for a client with which condition?
Fractured femur
Severe anorexia nervosa
Gastrointestinal obstruction
Chronic diarrhea and vomiting
The Correct Answer is C
Choice A reason: A fractured femur, while a serious injury, does not inherently contraindicate the use of lipid emulsions. These patients may require additional nutrition if they are unable to eat adequately by mouth, and lipid emulsions can be part of their parenteral nutrition regimen if needed.
Choice B reason: Severe anorexia nervosa is a condition that can lead to malnutrition and may necessitate the use of parenteral nutrition, including lipid emulsions, to provide essential nutrients. However, care must be taken to avoid refeeding syndrome, a potentially fatal condition that can occur when malnourished patients begin to refeed too quickly.
Choice C reason: Gastrointestinal obstruction is a condition that could be exacerbated by the administration of lipid emulsions. In cases of obstruction, enteral or parenteral nutrition may need to be carefully managed or avoided until the obstruction is resolved to prevent further complications. While lipid emulsions are a valuable component of parenteral nutrition, their use must be carefully considered in the context of the patient’s overall clinical condition. In the case of gastrointestinal obstruction, the nurse would be most concerned about the prescription of a lipid emulsion due to the potential for exacerbating the obstruction and complicating the patient’s condition.
Choice D reason: Chronic diarrhea and vomiting can lead to dehydration and electrolyte imbalances, but they do not directly contraindicate the use of lipid emulsions. However, the underlying cause of these symptoms should be addressed, and fluid and electrolyte balance should be carefully monitored.

Correct Answer is ["A","B","D"]
No explanation
Correct Answer is B
Explanation
Choice A reason: Heparin and warfarin do not work together to dissolve clots. Heparin acts quickly to prevent further clotting, while warfarin is used for long-term anticoagulation.
Choice B reason: Warfarin's onset of action is slow, requiring several days to reach therapeutic levels. During this time, heparin is used to provide immediate anticoagulation to prevent new clot formation or the growth of existing clots.
Choice C reason: IV heparin does not increase the effects of warfarin. They are used concurrently because of the delay in warfarin's onset of action.
Choice D reason: It is not appropriate to discontinue heparin immediately after starting warfarin due to the delay in warfarin reaching therapeutic levels. The overlap is necessary to ensure continuous anticoagulation.
