The critical care unit environment is very stressful for patients, families, and staff. What nursing action is directed at reducing environmental stress?
- A. Constant expert evaluation of patient status
- B. Limiting visits to immediate family
- C. Bathing all patients during hours of sleep
- D. Maintaining a quiet environment during hours of sleep
Correct Answer: D
Rationale: The correct answer is D: Maintaining a quiet environment during hours of sleep. This action is directed at reducing environmental stress in the critical care unit because noise and disturbances during sleep can negatively impact patients' rest and recovery. By ensuring a quiet environment, patients can have uninterrupted sleep, which is crucial for healing.
Rationale:
1. Constant expert evaluation of patient status (A) may be important but does not directly address environmental stress.
2. Limiting visits to immediate family (B) may hinder patients' emotional support and can be stressful for families.
3. Bathing all patients during hours of sleep (C) may disrupt patients' rest and increase stress levels rather than reduce it.

The nurse notes that the patient’s arterial blood gas levels indicate hypoxemia. The patient is not intubated and has a respiratory rate of 22 breaths/min. what is the nurse’s first intervention to relieve hypoxemia?
- A. Call the physician for an emergency intubation proced ure.
- B. Obtain an order for bilevel positive airway pressure (BiPAP).
- C. Provide for oxygen administration.
- D. Suction secretions from the oropharynx.
Correct Answer: C
Rationale: The correct answer is C: Provide for oxygen administration. The first intervention for hypoxemia is to increase oxygen levels to improve oxygen saturation in the blood. Oxygen administration can be achieved through various devices such as nasal cannula, face mask, or non-rebreather mask. This intervention helps to increase the oxygen supply to the patient's tissues and organs, addressing the underlying cause of hypoxemia. Calling for emergency intubation (choice A) is not the first step unless the patient's condition deteriorates. Obtaining an order for BiPAP (choice B) may be beneficial in some cases but is not the initial intervention for hypoxemia. Suctioning secretions (choice D) may be necessary if airway obstruction is present but is not the first step in addressing hypoxemia.
The patient is in need of immediate hemodialysis, but has no vascular access. The nurse prepares the patient for insertion of
- A. a percutaneous catheter at the bedside.
- B. a percutaneous tunneled catheter at the bedside.
- C. an arteriovenous fistula.
- D. an arteriovenous graft.
Correct Answer: A
Rationale: The correct answer is A: a percutaneous catheter at the bedside. This is the most appropriate option for immediate hemodialysis when the patient has no vascular access. A percutaneous catheter can be quickly inserted at the bedside, allowing for immediate initiation of hemodialysis.
Choice B, a percutaneous tunneled catheter, involves a more complex insertion process and is not typically done at the bedside. Choices C and D, arteriovenous fistula and arteriovenous graft, require advanced planning and surgical procedures, making them unsuitable for immediate hemodialysis in this scenario.
A nurse is caring for a patient in the final stages of dying. What is the most appropriate nursing action?
- A. Encourage the patient to eat to maintain strength.
- B. Provide emotional support and comfort measures.
- C. Perform frequent assessments to monitor for recovery signs.
- D. Implement aggressive interventions to prolong life.
Correct Answer: B
Rationale: The correct answer is B: Provide emotional support and comfort measures. In the final stages of dying, the focus shifts from curative treatment to providing comfort and dignity. Emotional support helps alleviate anxiety and fear, promoting a peaceful transition. Comfort measures like pain management improve quality of life. Encouraging the patient to eat may be futile as the body shuts down. Performing frequent assessments for recovery signs is not appropriate in this situation. Implementing aggressive interventions could go against the patient's wishes for a natural death.
While waiting for cardiac transplantation, a patient with severe cardiomyopathy has a ventricular assist device (VAD) implanted. When planning care for this patient, the nurse should anticipate:
- A. Giving immunosuppressive medications.
- B. Preparing the patient for a permanent VAD.
- C. Teaching the patient the reason for complete bed rest.
- D. Monitoring the surgical incision for signs of infection.
Correct Answer: D
Rationale: The correct answer is D because monitoring the surgical incision for signs of infection is essential post-VAD implantation to prevent complications. This step is crucial in early identification and treatment of any potential infection, which can lead to serious outcomes.
A) Giving immunosuppressive medications is not typically required for VAD implantation, as the primary goal is to support cardiac function rather than prevent rejection.
B) Preparing the patient for a permanent VAD is premature, as the goal is often to bridge to transplantation or recovery, not permanent VAD placement.
C) Teaching the patient the reason for complete bed rest is not necessary for VAD implantation, as patients are typically encouraged to gradually increase activity levels under guidance.
What diagnostic procedure is required to make a definitive diagnosis of pulmonary embolism?
- A. Arterial blood gas (ABG) analysis.
- B. Chest x-ray examination.
- C. High resolution multidetector CT angiogram.
- D. Ventilation-perfusion scanning.
Correct Answer: C
Rationale: The correct answer is C: High resolution multidetector CT angiogram. This diagnostic procedure is required for a definitive diagnosis of pulmonary embolism because it provides detailed imaging of the pulmonary vasculature, allowing visualization of blood clots in the pulmonary arteries.
A: Arterial blood gas (ABG) analysis does not directly diagnose pulmonary embolism but may show signs of hypoxemia or respiratory alkalosis, which can be seen in some cases of pulmonary embolism.
B: Chest x-ray examination may show nonspecific findings such as atelectasis or pleural effusion but cannot definitively diagnose pulmonary embolism.
D: Ventilation-perfusion scanning is another imaging modality used in the diagnosis of pulmonary embolism, but it is less commonly used compared to CT angiogram due to lower sensitivity and specificity.
