ATI Fundamentals Proctored Exam 2024

Correct Answer: D

Rationale: Preserving skin integrity plays a key role in breaking the chain of infection by eliminating the portal of entry for pathogens. When the skin is intact, it acts as a natural barrier that prevents pathogens from entering the body. By maintaining skin integrity through proper hygiene and wound care, the risk of infection is significantly reduced, disrupting the cycle of infection transmission.

Correct Answer: B

Rationale: During a Romberg test, the patient is asked to stand with feet together and arms at the sides. The test evaluates proprioception and vestibular function by assessing the patient's ability to maintain balance with eyes closed. Asking the patient to stand helps to detect any balance issues or disturbances in the absence of visual input.

Correct Answer: B

Rationale: Body hair plays an active role in preventing infection by acting as a filter to block pathogens. It helps to prevent harmful substances from entering the body through the skin, providing a physical barrier against potential infections.

Correct Answer: D

Rationale: A patient being kept off food and fluids before surgery can lead to dehydration. Dehydration can cause a slight increase in body temperature, which could explain the elevated oral temperature reading of 99.8�F (37.7�C) in this scenario. Infections are more likely to cause higher fevers, hypothermia would present with a lower temperature, and anxiety typically does not directly affect body temperature in this manner.

Correct Answer: D

Rationale: In patients with COPD, the respiratory drive is often stimulated by low oxygen levels. Administering too much oxygen can inhibit this hypoxic drive, leading to respiratory depression and potential respiratory failure. Therefore, it is crucial to carefully regulate the oxygen therapy to prevent the inhibition of the respiratory hypoxic stimulus in COPD patients.
