HESI RN CAT Exit Exam

Correct Answer: A

Rationale: The correct answer is A: 'Blow cool air from a hairdryer under the cast.' Blowing cool air can help relieve itching without damaging the cast or causing injury. Choice B, twisting the cast back and forth, can lead to discomfort, skin irritation, or even injury. Choice C, shaking powder into the cast, can create a mess, increase the risk of skin issues, and interfere with proper healing. Choice D, pushing a pencil under the cast edge, is dangerous as it can cause injury to the child's skin or the underlying tissues. Therefore, the safest and most effective option to relieve itching under the cast is to blow cool air from a hair dryer.

Correct Answer: C

Rationale: Pain in the lower back is a significant finding in an older client as it can indicate underlying issues such as kidney problems, spinal issues, or even aortic aneurysm. These conditions can be serious and require prompt medical attention. Decreased urine output (choice A) could indicate dehydration or kidney issues but is not as urgent as lower back pain. Loss of appetite (choice B) may be concerning but is not as critical as the potential life-threatening conditions associated with lower back pain. A persistent cough (choice D) is important to assess but is generally not as urgent as the potential serious implications of lower back pain in an older client.

Correct Answer: A

Rationale: The correct response is to acknowledge the client's question and open the door for further discussion by asking if they have questions about dying. This approach allows the nurse to address the client's concerns and fears, promoting open communication and providing emotional support. Choices B and C do not encourage further dialogue about the client's feelings and concerns regarding death. Choice D briefly acknowledges the question but does not actively invite the client to express their thoughts and emotions regarding dying.

Correct Answer: C

Rationale: The correct answer is C: 'The full thickness burn has destroyed the nerves.' In full thickness burns, also known as third-degree burns, the nerve endings are destroyed, leading to a lack of pain sensation at the site of the burn. The description of the burn as dry, waxy, and white indicates a full thickness burn. Choices A, B, and D are incorrect because they do not explain the absence of pain in full thickness burns. Choice A is incorrect as a full-thickness burn involves significant tissue destruction. Choice B is incorrect because nerve compression would not explain the lack of pain in this context. Choice D is incorrect because second-degree burns, unlike full-thickness burns, are painful due to nerve endings being intact.

Correct Answer: D

Rationale: The correct instruction for an elderly client taking both an ACE inhibitor and a calcium channel blocker is to change positions slowly. Both medications can lead to orthostatic hypotension, a sudden drop in blood pressure when changing positions, which can increase the risk of falls. Instructing the client to change positions slowly helps prevent falls. Wearing long-sleeved clothing when outdoors does not directly relate to the medication combination. Reporting the onset of a sore throat is important for monitoring potential side effects but is not specific to these medications. While potassium levels should be monitored with ACE inhibitors, eating plenty of potassium-rich foods without guidance can lead to hyperkalemia, a potential side effect of ACE inhibitors.
