HESI RN CAT Exam Quizlet

Correct Answer: C

Rationale: The correct answer is to aspirate for blood return before injecting. This action helps ensure that the needle is not in a blood vessel, reducing the risk of injury. Using a 1-inch needle (Choice A) is a standard length for intramuscular injections but does not directly reduce the risk of injury. Selecting a large muscle for the injection (Choice B) is important for proper medication absorption but does not directly reduce the risk of injury. Massaging the injection site (Choice D) can help with medication absorption but does not reduce the risk of injury.

Correct Answer: C

Rationale: The correct intervention for a client at risk for developing deep vein thrombosis (DVT) is to encourage early ambulation. Early ambulation helps prevent DVT by promoting circulation, reducing stasis, and preventing blood clot formation. Maintaining the client on bed rest (Choice A) would increase the risk of DVT due to decreased mobility. Applying warm, moist compresses to the legs (Choice B) can be beneficial for other conditions but does not directly prevent DVT. Massaging the legs daily (Choice D) can dislodge a blood clot, leading to serious complications in a client at risk for DVT.

Correct Answer: D

Rationale: In the oliguric phase of acute renal failure (ARF), the goal is to prevent fluid overload. Since the client has a low urine output of 400 ml in 24 hours, limiting oral intake to 900 to 1,000 ml is appropriate. Encouraging unrestricted oral fluids (Choice A) can exacerbate fluid overload. Decreasing oral intake to 200 ml (Choice B) would be too restrictive and may lead to dehydration. Allowing the client to have exactly 400 ml oral intake (Choice C) would not account for other sources of fluid intake and output, potentially resulting in fluid imbalance.

Correct Answer: D

Rationale: When obtaining a urine specimen from a female infant, securing the pediatric urine collector bag to the perineum is the most appropriate intervention. This method allows for non-invasive collection of urine without causing discomfort or distress to the infant. Placing the wet diaper in a biohazard specimen bag (Choice A) is incorrect as it does not involve collecting a fresh urine sample. Using a catheter (Choice B) is invasive and not typically necessary for routine urine specimen collection from infants. Collecting the urinary stream in mid-air when the infant cries (Choice C) is not a reliable or hygienic method of obtaining a urine specimen.

Correct Answer: B

Rationale: The correct answer is to ask the girl if she will be eating her breakfast this morning. This is important to determine if the child will be consuming food, which is crucial information before administering insulin. If the child does not plan to eat, administering the full dose of insulin may lead to hypoglycemia. Choice A is incorrect as administering the insulin without knowing if the child will eat can be dangerous. Choice C is not the first intervention because the immediate concern is the child's meal intake. Choice D, while important, is not the first step in this situation.
