HESI 799 RN Exit Exam Capstone

Correct Answer: B

Rationale: Corrected Rationale: Prolonged exposure to high oxygen concentrations can disrupt the production of surfactant in the lungs, leading to atelectasis and other lung complications. Surfactant is essential for maintaining lung compliance and preventing alveolar collapse. Reduced cardiac output (Choice A) is not directly associated with prolonged oxygen exposure. Hyperactivity of alveoli (Choice C) is not a recognized consequence of high oxygen levels. Increased oxygen carrying capacity (Choice D) is not a pathophysiological effect of prolonged high oxygen exposure.

Correct Answer: B

Rationale: Fixed, dilated pupils are a sign of increased intracranial pressure or brain injury, indicating a potentially serious neurological condition. Flaccid paralysis, although concerning, may not always indicate immediate life-threatening issues. Diminished spinal reflexes and reduced sensory responses are important neurological assessments but are not as acutely concerning as fixed, dilated pupils in this context.

Correct Answer: A

Rationale: The nurse's signature on a surgical consent form signifies that the client voluntarily grants permission for the procedure to be done. This is the correct answer because the nurse's signature does not imply the client's competence, understanding of risks and benefits, or that the client signed the form freely and voluntarily. The nurse's role is to verify that the client has made an informed decision and is providing consent for the procedure.

Correct Answer: A

Rationale: In a post-tonsillectomy and adenoidectomy patient, frequent swallowing is a crucial assessment that requires immediate attention by the nurse. Frequent swallowing can indicate bleeding, a complication that needs urgent intervention. Coughing may be expected due to irritation from the surgery but is not as concerning as potential bleeding. Slow breathing and tachycardia are not typically immediate concerns following this type of surgery.

Correct Answer: B

Rationale: Turning and repositioning a client is within the scope of practice of a UAP. This task helps prevent pressure ulcers and assists in maintaining the client's comfort and mobility. Assessing pain level post-surgery requires clinical judgment and interpretation, making it appropriate for a PN or RN. Administering medication like insulin involves critical thinking and potential adjustments based on the client's condition, which is the responsibility of a licensed nurse. Changing postoperative dressings involves wound assessment, infection control, and knowledge of aseptic techniques, tasks that fall under the purview of a PN or RN.
