Correct Answer: B

Rationale: The correct answer is B: Bloody stools. Bloody stools are a common symptom of Crohn's disease, characterized by inflammation of the digestive tract. Weight gain (choice A) is less likely due to malabsorption issues associated with Crohn's disease. Urinary retention (choice C) is not directly related to Crohn's disease. Abdominal distention (choice D) may occur in Crohn's disease but is not as specific a finding as bloody stools.

Correct Answer: A

Rationale: The correct answer is A: "Glucose 180 mg/dL." Elevated glucose levels in a client receiving TPN may indicate hyperglycemia, which can lead to complications such as osmotic diuresis, dehydration, and electrolyte imbalances. It is essential to report this finding to the provider for further evaluation and management. Choices B, C, and D are within normal ranges and do not indicate immediate concerns related to TPN administration.

Correct Answer: C

Rationale: The correct answer is C. Using both breasts at each feeding helps ensure adequate milk production and consumption. Option A is incorrect because breastfeeding should be done on demand rather than following a strict schedule. Option B is incorrect as limiting feeding time to 5 minutes per breast may not provide the baby with enough milk. Option D is also incorrect as pumping should not replace direct breastfeeding unless there is a specific medical reason to do so.

Correct Answer: C

Rationale: The correct action the nurse should take when administering vancomycin IV is to assess the IV site for infiltration during administration. Vancomycin is known to cause tissue damage if it infiltrates, making close monitoring crucial. Administering the medication over 30 minutes (Choice A) is a common practice but not the priority in preventing infiltration. Monitoring for a decrease in blood pressure (Choice B) is not directly related to vancomycin administration. Premedicating with an antiemetic (Choice D) is not typically required for vancomycin administration.

Correct Answer: A

Rationale: Priming the IV tubing with 0.9% sodium chloride is crucial before administering packed RBCs as it prevents hemolysis and ensures the safe transfusion of blood. Using a smaller 20- to 22-gauge IV catheter is recommended for packed RBCs to prevent hemolysis due to the small tubing size and faster flow rate. Obtaining filterless IV tubing is incorrect as blood products should be administered through a specialized filter to prevent potential clots or contaminants from reaching the patient. Placing blood in the warmer for an hour is unnecessary and could lead to overheating, potentially causing harm to the patient.
