Critical Care Nursing NCLEX Questions Questions

Question 1 of 5

A patient�s status deteriorates and mechanical ventilation i s now required. The pulmonologist wants the patient to receive 10 breaths/min from the ventilaabtirobr.c bomu/tt ewst ants to encourage the patient to breathe spontaneously in between the mechanical breaths at his own tidal volume. This mode of ventilation is referred to by what term?

Correct Answer: C

Rationale: Rationale: 1. Intermittent Mandatory Ventilation (IMV) allows the patient to breathe spontaneously between the preset mechanical breaths. 2. It provides a set number of breaths per minute while allowing the patient to initiate additional breaths at their own tidal volume. 3. IMV is a partial ventilatory support mode, providing a balance between controlled and spontaneous breathing. 4. Assist/Control Ventilation (A) provides full support with every breath initiated by the patient or the ventilator. 5. Controlled Ventilation (B) does not allow for spontaneous breaths by the patient. 6. Positive End-Expiratory Pressure (D) is a separate mode focusing on maintaining positive pressure at the end of expiration, not providing breaths.

Question 2 of 5

The nurse is caring for a patient who has a temporary percutaneous dialysis catheter in place. In caring for this patient, the nurse should

Correct Answer: C

Rationale: The correct answer is C because assessing the catheter site for redness and/or swelling is crucial for early detection of infection. Redness and swelling are common signs of infection at the catheter site, which requires prompt intervention. Applying a sterile gauze dressing (choice A) is not necessary for a temporary percutaneous dialysis catheter. Replacing the transparent dressing every 10 days (choice B) is not recommended as it can increase the risk of infection. Using the catheter for drawing blood samples (choice D) is not appropriate as it can introduce contaminants and increase the risk of infection. Regular assessment of the catheter site is essential for early detection and prevention of complications.

Question 3 of 5

The nurse educator is evaluating the care that a new registered nurse (RN) provides to a patient receiving mechanical ventilation. Which action by the new RN indicates the need for more education?

Correct Answer: D

Rationale: The correct answer is D because positioning the patient with the head of the bed at 10 degrees is incorrect for a patient receiving mechanical ventilation. The optimal position for such patients is to elevate the head of the bed to 30-45 degrees to prevent aspiration and improve oxygenation. Option A is incorrect as increasing FIO2 before suctioning is appropriate to ensure adequate oxygenation. Option B is incorrect as securing a bite block in place using adhesive tape is a standard practice to prevent the patient from biting on the endotracheal tube. Option C is incorrect as asking for assistance to reposition the endotracheal tube shows the RN is aware of the importance of proper placement to ensure effective ventilation.

Question 4 of 5

A critical care unit has decided to implement several measures designed to improve intradisciplinary and interdisciplinary collaboration. In addition to an expected improvement in patient outcomes, what is the most important effect that should resultf rom these measures?

Correct Answer: C

Rationale: Rationale: - Improved collaboration enhances job satisfaction and reduces burnout, leading to increased staff retention. - Higher staff retention promotes continuity of care, improves team dynamics, and enhances patient outcomes. Summary: - A: Not directly related to collaboration, more about performance evaluation. - B: Manners may improve, but not the most important effect of collaboration. - D: Collaboration involves open communication, so less discussion in front of patients is not a positive outcome.

Question 5 of 5

The nurse is caring for four patients on the progressive car e unit. Which patient is at greatest risk for developing delirium?

Correct Answer: C

Rationale: The correct answer is C, the 86-year-old postoperative from colonic resection. This patient is at the greatest risk for delirium due to being elderly, having undergone surgery, and having a history of being from a nursing home. These factors contribute to an increased susceptibility to delirium. A: The 36-year-old with alcohol withdrawal may be at risk for delirium tremens, but the older age of the patient in choice C places them at higher risk. B: The 54-year-old with an elevated creatinine level postoperative is at risk for complications, but age and history of nursing home placement increase the risk for delirium in choice C. D: The 95-year-old with community-acquired pneumonia is at risk for delirium, but the combination of age, surgery, and nursing home history in choice C presents a greater risk.
