A nurse is preparing to administer intermittent lipid emulsion and notes a layer of fat floating in the IV solution bag. Which action should the nurse take?
Shake the bag to mix the fat.
Administer the bag of solution.
Return the bag to the pharmacy.
Turn the bag upside down one time.
The Correct Answer is C
Choice A reason:Shaking the bag is not recommended as it may not adequately mix the solution and could cause emulsion instability.
Choice B reason:Administering the bag as is could be harmful due to the risk of fat embolism or other complications from an unstable emulsion.
Choice C reason:Returning the bag to the pharmacy is the appropriate action to ensure the client receives a properly mixed and safe emulsion.
Choice D reason:Turning the bag upside down one time is not sufficient to mix the emulsion and does not address the potential instability of the solution.

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.
Correct Answer is A
Explanation
Choice A reason:Increased serum amylase is a common finding in acute pancreatitis as it is released from the inflamed pancreas[^10^].
Choice B reason:A decreased WBC count is not typically associated with acute pancreatitis; an increased count may indicate infection or inflammation.
Choice C reason:Serum calcium is often decreased in acute pancreatitis due to fat saponification and hypoalbuminemia.
Choice D reason:Decreased serum lipase would not be expected; increased levels are indicative of acute pancreatitis, similar to amylase[^10^].
