A client was seen in the emergency room with a complaint of severe episodes of vomiting and diarrhea, and complains of feeling lightheaded.
Which laboratory test should the nurse prioritize?

Choice A rationale

Preparing the client for lithotripsy is important for treatment but is not the immediate highest priority in an emergency setting. Immediate pain management takes precedence.

Choice B rationale

Ordering a renal ultrasound is necessary for assessing the stones but comes after stabilizing the client's acute symptoms, including managing pain.

Choice C rationale

Administering pain medication as prescribed is the highest priority because renal colic causes severe pain. Immediate pain relief is crucial for the client's comfort and to facilitate further diagnostic and therapeutic interventions.

Choice D rationale

Initiating IV fluid therapy is important for hydration and possibly aiding stone passage but follows after addressing the acute pain.

Choice A rationale

Total parenteral nutrition (TPN) provides essential nutrients intravenously, allowing the bowel to rest and heal, which is important in the management of inflammatory bowel disease (IBD).

Choice B rationale

While reducing inflammation and controlling symptoms are important goals in IBD management, TPN is primarily used to provide nutrition and allow the bowel to rest.

Choice C rationale

Stimulating the bowel is not the purpose of TPN. TPN is used to give the digestive tract a break while ensuring the patient receives necessary nutrients.

Choice D rationale

Preventing malnutrition and promoting weight gain are secondary benefits of TPN, but the primary rationale is to provide nutrients while allowing the bowel to rest and heal.
