How can preserving skin integrity impact the circular chain of infection?

A. Host

B. Reservoir

C. Mode of transmission

D. Portal of entry

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.

A client has a new diagnosis of tuberculosis and has been placed on a multi-medication regimen. Which of the following instructions should the nurse give the client related to ethambutol?

• A. Your urine can turn a dark orange.
• B. Watch for a change in the sclera of your eyes.
• C. Watch for any changes in vision.
• D. Take vitamin B6 daily.

Correct Answer: C: Watch for any changes in vision.
Rationale: Ethambutol is associated with potential vision changes, including optic neuritis. Patients should be instructed to report any visual disturbances immediately to prevent permanent vision loss. Monitoring for changes in vision is crucial to detect any adverse effects early on and prevent serious complications.

A nurse is orienting a newly licensed nurse on performing a routine assessment of a client who is receiving mechanical ventilation via an endotracheal tube. Which of the following information should the nurse include in the teaching?

• A. Apply a vest restraint if self-extubation is attempted.
• B. Monitor ventilator settings every 8 hours.
• C. Document tube placement in centimeters at the angle of the jaw.
• D. Assess breath sounds every 1 to 2 hours.

Correct Answer: D
Rationale: Assessing breath sounds every 1 to 2 hours is crucial in monitoring the client's respiratory status and identifying any potential complications promptly. Monitoring ventilator settings every 8 hours is important for overall ventilation management. Documenting the endotracheal tube placement accurately is essential to ensure proper positioning. Using a vest restraint if self-extubation is attempted is not a recommended intervention as it can lead to complications and should be avoided.

When is sterile technique used?

• A. During strict isolation procedures
• B. After terminal disinfection is performed
• C. For invasive procedures
• D. When protective isolation is necessary

Correct Answer: C
Rationale: Sterile technique is utilized during invasive procedures to prevent the introduction of pathogens, minimizing the risk of infections. This strict approach ensures that the procedure is performed in a sterile environment, reducing the chances of contamination and subsequent complications.

What is the most important legal responsibility for the healthcare team after a patient's death in a hospital?

• A. Obtaining consent for an autopsy
• B. Notifying the coroner or medical examiner
• C. Labeling the body appropriately
• D. Ensuring the attending physician issues the death certificate

Correct Answer: D
Rationale: After a patient's death in a hospital, the most crucial legal responsibility for the healthcare team is ensuring that the attending physician issues the death certificate. The death certificate is a vital legal document that confirms the cause of death and is required for legal and administrative purposes, including the completion of the patient's medical records and facilitating the family's ability to proceed with funeral arrangements and insurance claims. While other actions such as obtaining consent for an autopsy, notifying the coroner or medical examiner, and labeling the body appropriately are important, ensuring the timely and accurate issuance of the death certificate takes precedence in this scenario.
