A critical care nurse is caring for a client diagnosed with acute pancreatitis. The nurse knows this client should be started on parenteral nutrition (PN) after what indications?
5% deficit in body weight compared to pre-illness weight and increased caloric need.
Significant risk of aspiration coupled with decreased level of consciousness.
Calorie deficit and muscle wasting combined with low electrolyte levels.
Inability to take in adequate oral food or fluids within 7 days.
The Correct Answer is D
Choice A rationale
A 5% deficit in body weight and increased caloric need alone do not warrant the initiation of parenteral nutrition (PN). PN is typically reserved for situations where oral or enteral feeding is not feasible or safe.
Choice B rationale
Significant risk of aspiration and decreased level of consciousness may necessitate alternative feeding methods, such as enteral feeding via a nasogastric or gastrostomy tube. PN is considered when enteral feeding is not possible.
Choice C rationale
Calorie deficit, muscle wasting, and low electrolyte levels indicate malnutrition, but PN is initiated when other feeding methods are inadequate or unsafe.
Choice D rationale
Inability to take in adequate oral food or fluids within 7 days is a clear indication for initiating PN. This ensures the patient receives essential nutrients and prevents further deterioration of their nutritional status.

Correct Answer is C
Explanation
Choice A rationale
Aspiration of synovial fluid for serologic testing is a procedure known as arthrocentesis, which involves extracting joint fluid for analysis. While useful for diagnosing conditions like infections or arthritis, it is not the same as arthrography, which involves imaging.
Choice B rationale
Injection of corticosteroids into the client's knee joint to facilitate ROM is a therapeutic procedure to reduce inflammation and improve movement in conditions like arthritis, but it is not part of an arthrography procedure.
Choice C rationale
Injection of a contrast agent into the knee joint prior to ROM exercises is a key part of arthrography. The contrast agent helps to enhance the imaging of the joint structures during movement, allowing for a detailed assessment of the joint.
Choice D rationale
Replacement of the client's synovial fluid with a synthetic substitute is not related to arthrography. This description aligns more with viscosupplementation, a treatment for osteoarthritis.
Correct Answer is A
Explanation
Choice A rationale
Assessing the client's verbal response is the first step in evaluating their level of consciousness (LOC). It provides immediate information about their ability to communicate and follow commands.
Choice B rationale
Assessing the client's response to pain is a later step in the LOC assessment if the client does not respond to verbal stimuli. It helps determine the level of consciousness if the client is not verbally responsive.
Choice C rationale
Assessing the client's judgment is part of a cognitive assessment but is not the first action when assessing LOC. It evaluates higher brain functions, not the initial level of responsiveness.
Choice D rationale
Assessing the client's ability to follow complex commands is part of a cognitive assessment and provides information about higher brain function but is not the first step in LOC assessment.
