HESI CAT Exam 2022

Correct Answer: A

Rationale: The correct intervention the nurse should implement during the administration of a vesicant chemotherapeutic agent via an IV site in the client's arm is to assess the IV site frequently for signs of extravasation. Vesicants are agents that can cause tissue damage if they leak into the surrounding tissues. Monitoring for signs of extravasation such as swelling, pain, or redness is crucial to prevent tissue damage and ensure prompt intervention if extravasation occurs. Choices B, C, and D are incorrect because monitoring capillary refill, applying a topical anesthetic for burning, and explaining temporary burning do not directly address the risk of extravasation associated with vesicant chemotherapeutic agents.

Correct Answer: A

Rationale: The correct instruction to include in the discharge plan for a client with MS to reduce symptom exacerbation is practicing relaxation exercises. Relaxation exercises can help manage MS symptoms by reducing stress. Limiting fluids to avoid bladder distention is not appropriate as adequate hydration is essential for overall health and helps prevent complications like urinary tract infections. While spacing activities to allow for rest periods can be beneficial for general well-being, it is not directly related to symptom exacerbation in MS. Avoiding persons with infections is important to prevent infections, but it is not specifically targeted at reducing MS symptom exacerbation.

Correct Answer: A

Rationale: The correct action for the nurse to implement when caring for a client with a radioactive Cesium-loaded vaginal applicator during brachytherapy is to wear a dosimeter film badge when in the client's room. Wearing a dosimeter badge is essential to monitor radiation exposure and ensure the safety of healthcare providers. Choice B is incorrect as the duration is not specified and unnecessary. Choice C is incorrect as changing linens daily does not directly relate to radiation safety. Choice D is incorrect as using gloves to remove the applicator if dislodged is important but not the primary action to monitor radiation exposure.

Correct Answer: A

Rationale: Lethargy and difficulty arousing may indicate hypoglycemia, which should be assessed before other actions. Performing a finger stick glucose test is crucial to evaluate the child's blood sugar levels and address hypoglycemia promptly. Increasing the IV fluid flow rate is not indicated without knowing the glucose status. Reviewing 24-hour intake and output is important but not the priority when lethargy and difficulty arousing are present. Obtaining arterial blood gases is not the primary assessment needed in this situation.

Correct Answer: A

Rationale: The correct sequence for preparing a dose of insulin involves ensuring proper aseptic technique. First, clean the vial's rubber stopper with an alcohol swab to prevent contamination. Second, withdraw the correct dose of insulin to be administered. Lastly, inject air equal to the insulin dose into the vial to maintain proper pressure for withdrawing the medication. This sequence ensures the medication is prepared safely and accurately. Choice A is correct as it follows this sequence. Choices B, C, and D present incorrect sequences that may compromise patient safety by not following the correct aseptic technique. Choice B injects air into the vial before withdrawing insulin, which is incorrect. Choice C reverses the order of withdrawing insulin and injecting air. Choice D withdraws the insulin before injecting air, which can affect the pressure inside the vial and lead to inaccurate dosing.
