HESI CAT Exam 2022

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: B

Rationale: The correct intervention for the nurse to implement first is to place a mask on the client's face. This is crucial to prevent the potential spread of infectious agents to others in the emergency department, considering the presenting symptoms of coughing and fever. Placing a mask helps in containing respiratory secretions and reducing the risk of airborne transmission. Assessing the client's temperature or blood pressure can be done after ensuring infection control measures. Obtaining a chest X-ray would be a secondary intervention once immediate infection control is addressed.

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.

Correct Answer: C

Rationale: The correct intervention for a patient with tetanus is to minimize the amount of stimuli in the room. Tetanus can lead to muscle spasms and heightened sensitivity to stimuli, making it essential to reduce environmental triggers for the patient's comfort and safety. Opening window shades for natural light (Choice A) may exacerbate sensitivity to light and worsen symptoms. Encouraging coughing and deep breathing (Choice B) is not directly related to managing tetanus symptoms. While repositioning the patient every hour (Choice D) is important for preventing pressure ulcers, it is not the priority when managing tetanus, which requires a quiet, low-stimulus environment to minimize muscle spasms and discomfort.

Correct Answer: C

Rationale: For a postpartum client who is bottle feeding and develops breast engorgement, the best recommendation is to avoid stimulation of the breasts and wear a tight bra. This helps reduce engorgement by decreasing blood flow to the breasts. Option A is incorrect because exposing the breasts to air can further stimulate them, worsening engorgement. Option B is incorrect as warm packs can increase blood flow and exacerbate engorgement. Option D is incorrect as expressing breast milk can lead to further stimulation and increased engorgement.
