While recovering from the anesthetic, what is the best position for Mrs. West?
- A. Supine with legs fully extended
- B. Prone with head turned to the side
- C. Lateral Sims with legs flexed
- D. Trendelenburg with head to the side
Correct Answer: D
Rationale: The correct answer is D: Trendelenburg with head to the side. This position helps prevent aspiration by promoting drainage of secretions from the mouth and reducing the risk of airway obstruction. Placing the patient in Trendelenburg position with the head to the side also helps facilitate proper blood flow and ventilation. Supine with legs fully extended (A) may increase the risk of airway obstruction and aspiration. Prone with head turned to the side (B) may obstruct the airway and hinder breathing. Lateral Sims with legs flexed (C) is not suitable for a patient recovering from anesthesia as it may not provide optimal airway clearance and respiratory support.
Which step in the chain of infection refers to how a pathogen is transferred or moved from its reservoir to the susceptible host?

While caring for a client receiving positive-pressure mechanical ventilation, which intervention should the nurse NOT implement to prevent complications?
- A. Elevate the head of the bed to at least 30°.
- B. Verify the prescribed ventilator settings daily.
- C. Administer pantoprazole as prescribed.
- D. Reposition the endotracheal tube to the opposite side of the mouth daily.
Correct Answer: D
Rationale: The correct answer is D. Repositioning the endotracheal tube to the opposite side of the mouth daily is not necessary and could potentially lead to complications such as accidental extubation or damage to the airway. A: Elevating the head of the bed helps prevent aspiration. B: Verifying ventilator settings daily ensures proper functioning. C: Administering pantoprazole helps prevent stress ulcers. In summary, D is incorrect because it is unnecessary and poses risks, while A, B, and C are important interventions to prevent complications associated with positive-pressure mechanical ventilation.
Until Mr. Jones’ diagnosis is confirmed, what should be a priority?
- A. Encouraging rest
- B. Monitoring intake and output
- C. Preventing spread of infection to others
- D. Providing attractive meals
Correct Answer: C
Rationale: The correct answer is C: Preventing spread of infection to others. This is the priority because until Mr. Jones' diagnosis is confirmed, it is crucial to prevent potential transmission of any infectious diseases to others. Encouraging rest (choice A) and providing attractive meals (choice D) are important for overall well-being but not as critical as preventing the spread of infection. Monitoring intake and output (choice B) is important for assessing Mr. Jones' health status but does not directly address the potential risk of infecting others. Therefore, choice C is the most immediate priority to ensure the safety of others.
