Fundamentals HESI

Correct Answer: A

Rationale: Collapsing the device when it is 1/2 to 2/3 full of air is the correct nursing action to ensure proper operation of a closed wound suction device (hemovac). This action maintains negative pressure, which is essential for proper suction and drainage of the wound. Emptying the device every 4 hours (Choice B) is not necessary as the focus should be on collapsing it appropriately. Replacing the device every 24 hours (Choice C) is not a standard practice unless indicated by the healthcare provider. Keeping the device above the level of the surgical site (Choice D) is not necessary for the device's proper operation; collapsing it to maintain negative pressure is the key action.

Correct Answer: C

Rationale: A full urine collection bag can cause the device to pull away from the skin, leading to potential leakage and skin irritation. Choice A is incorrect because a full urine collection bag does not force urine to back up into the kidneys. Choice B is incorrect as a full collection bag does not suppress the production of urine. Choice D is incorrect as a full collection bag is unlikely to tear the ileal conduit.

Correct Answer: A

Rationale: The correct answer is A. Warmth around the infusion site is not an expected finding with infiltration. Infiltration typically presents with swelling and coolness due to the fluid leaking into the surrounding tissue. Choices B, C, and D are incorrect because swelling, coolness, and difficulty flushing the line, as well as lack of blood return, are commonly associated with infiltration.

Correct Answer: D

Rationale: Complaints of back pain and shortness of breath are classic signs of a transfusion reaction, specifically indicating a hemolytic reaction. This reaction can lead to the release of hemoglobin into the bloodstream, causing back pain and shortness of breath due to clot formation in the blood vessels, leading to decreased oxygen delivery. Warmth, flushing, rash, chills, and fever are more commonly associated with allergic reactions or febrile non-hemolytic reactions during transfusions. Therefore, options A, B, and C are incorrect in this context.

Correct Answer: B

Rationale: The correct answer is to tell the client to keep the head of the bed elevated at least 30�. Elevating the head of the bed prevents aspiration of the enteral formula, which is a priority in caring for a client with an NG tube. This action helps in reducing the risk of complications such as pneumonia. Choices A, C, and D are incorrect. While rinsing the feeding bag, ensuring the enteral formula temperature, and maintaining cleanliness are important aspects of enteral feeding care, the priority is to prevent aspiration by keeping the head of the bed elevated. These actions can be implemented after ensuring the client's safety by maintaining the correct bed position.
