Correct Answer: C

Rationale: The correct answer is C because obtaining certification in critical care nursing demonstrates the nurse's personal expertise in the specialty. Certification confirms the nurse's advanced knowledge and skills, enhancing professional credibility and potential for career advancement. This choice focuses on the individual nurse's competency and dedication to the specialty. Incorrect choices: A: Salary increase is not the primary benefit of certification, although it may be a potential outcome. B: Certification is often preferred but not always required to work in critical care. D: Employers may encourage certification, but it is not always mandated.

Correct Answer: A

Rationale: The correct answer is A: Adherence to procedures by nursing staff. This should be evaluated first because medication errors are often caused by human factors such as staff not following proper procedures. By assessing adherence, the root cause of errors can be identified and addressed. Choice B: Clarity of interdisciplinary communication may contribute to errors but doesn't directly address staff adherence to procedures. Choice C: Number of new employees could be a factor, but focusing on adherence to procedures is more crucial. Choice D: Changes in administration procedures may impact errors, but evaluating staff adherence is more immediate and directly related to errors.

Correct Answer: A

Rationale: The correct answer is A: Drain condensate from the ventilator tubing away from the patient. This is crucial to prevent ventilator-associated pneumonia as stagnant condensate can harbor harmful bacteria. By draining it away from the patient, the risk of bacterial growth and subsequent aspiration is minimized. Elevating the head of the bed (choice B) helps prevent aspiration but is not specific to preventing ventilator-associated pneumonia. Instilling normal saline during suctioning (choice C) can increase the risk of infection. Performing regular oral care with chlorhexidine (choice D) is important for oral hygiene but not directly related to preventing ventilator-associated pneumonia.

Correct Answer: B

Rationale: The correct answer is B: Contact the hospital’s interpreter service for someone to translate. This is the best option as it ensures accurate communication between the nurse, patient, and family. Hospital interpreters are trained professionals who can accurately convey medical information, ensuring understanding and informed decision-making. Using Google search (A) may result in inaccurate information and is not reliable for medical communication. Asking a resident (C) who is fluent may not guarantee accuracy in medical terminology. Using a young family member (D) as a translator can lead to miscommunication due to potential language barriers or lack of medical knowledge. Overall, option B is the most appropriate and ethical choice for effective communication in a healthcare setting.

Correct Answer: C

Rationale: The correct answer is C: Tachycardia. Hypoxemia results in decreased oxygen levels in the blood, stimulating the body to increase heart rate to improve oxygen delivery. Tachycardia is an early sign of the cardiovascular system compensating for hypoxemia. Heart block (A) is a disruption in the electrical conduction within the heart and is not directly related to hypoxemia. Restlessness (B) is a non-specific sign and can be caused by various factors. Tachypnea (D) is an increased respiratory rate, which is a response to hypoxemia but not a direct effect on the cardiovascular system.
