To maintain proper cuff pressure of an endotracheal tube (ET) when the patient is on mechanical ventilation, the nurse should:
- A. Inflate the cuff with a minimum of 10 mL of air.
- B. Inflate the cuff until the pilot balloon is firm on palpation.
- C. Inject air into the cuff until a manometer shows 15 mm Hg pressure.
- D. Inject air into the cuff until a slight leak is heard only at peak inflation.
Correct Answer: D
Rationale: The correct answer is D because inflating the cuff until a slight leak is heard only at peak inflation ensures it is adequately sealed but not overinflated, preventing complications like tracheal injury or pressure necrosis. Choice A lacks specificity and can lead to overinflation. Choice B may result in overinflation as the firmness of the balloon is subjective. Choice C relies on a specific pressure reading, which may vary based on factors like tube size and patient anatomy, potentially leading to under- or overinflation.

During the primary assessment of a victim of a motor vehicle collision, the nurse determines that the patient is breathing and has an unobstructed airway. Which action should the nurse take next?
- A. Palpate extremities for bilateral pulses.
- B. Observe the patient’s respiratory effort.
- C. Check the patient’s level of consciousness.
- D. Examine the patient for any external bleeding.
Correct Answer: B
Rationale: Rationale: The correct action is to observe the patient's respiratory effort next. This step ensures that the patient's breathing remains stable and adequate. If respiratory effort is compromised, immediate intervention is required. Checking for bilateral pulses (A) is important but comes after ensuring respiratory status. Checking level of consciousness (C) is also crucial but not as immediate as monitoring breathing. Examining for external bleeding (D) is important but not the priority when airway and breathing are already determined to be clear.
What factors may predispose a patient to respiratory acido as bi is rb? . com/test
- A. Anxiety and fear
- B. Central nervous system depression
- C. Diabetic ketoacidosis
- D. Nasogastric suctioning
Correct Answer: B
Rationale: The correct answer is B: Central nervous system depression. This factor can lead to respiratory acidosis by depressing the respiratory drive, causing hypoventilation and retention of carbon dioxide. Anxiety and fear (A) may lead to hyperventilation, reducing carbon dioxide levels. Diabetic ketoacidosis (C) results in metabolic acidosis, not respiratory acidosis. Nasogastric suctioning (D) may cause respiratory alkalosis from excessive removal of carbon dioxide. Thus, central nervous system depression is the most likely factor predisposing a patient to respiratory acidosis.
What were identified as the first critical care units? (Select all that apply.)
- A. Burn units.
- B. Coronary care units
- C. Recovery rooms.
- D. Neonatal intensive care units.
Correct Answer: A
Rationale: The correct answer is A: Burn units. Burn units were identified as the first critical care units due to the complex and intensive care required by burn patients. These units were established to provide specialized care for burn victims, including wound management, infection control, and fluid resuscitation.
Summary:
- Burn units were the first critical care units due to the specialized care needed for burn patients.
- Coronary care units focus on cardiac conditions, not the first identified critical care units.
- Recovery rooms are for post-operative care, not specifically for critical care.
- Neonatal intensive care units are specialized for newborns, not the first critical care units.
The nurse is caring for a patient with a subarachnoid hemorrhage who is intubated and placed on a mechanical ventilator with 10 cm H2O of peak end-expiratory pressure (PEEP). When monitoring the patient, the nurse will need to notify the healthcare provider immediately if the patient develops:
- A. Oxygen saturation of 93%.
- B. Respirations of 20 breaths/minute.
- C. Green nasogastric tube drainage.
- D. Increased jugular venous distention.
Correct Answer: D
Rationale: The correct answer is D: Increased jugular venous distention. In a patient with a subarachnoid hemorrhage and on mechanical ventilation, increased jugular venous distention can indicate increased intracranial pressure, which can be life-threatening. The nurse should notify the healthcare provider immediately as it may require urgent intervention to prevent further neurological deterioration.
A: Oxygen saturation of 93% is within the acceptable range for a patient on mechanical ventilation and may not require immediate notification.
B: Respirations of 20 breaths/minute are within normal limits for a ventilated patient and do not necessarily indicate a critical condition.
C: Green nasogastric tube drainage may indicate the presence of bile and could be related to gastrointestinal issues, but it does not pose an immediate threat to the patient's neurological status.
When caring for a patient who has an arterial catheter in the left radial artery for arterial pressure-based cardiac output (APCO) monitoring, which information obtained by the nurse is most important to report to the health care provider?
- A. The patient has a positive Allen test.
- B. There is redness at the catheter insertion site.
- C. The mean arterial pressure (MAP) is 86 mm Hg.
- D. The dicrotic notch is visible in the arterial waveform.
Correct Answer: B
Rationale: The correct answer is B: There is redness at the catheter insertion site. Redness at the catheter insertion site could indicate infection, which is a serious complication that requires immediate attention to prevent sepsis. Reporting this to the healthcare provider promptly is crucial for timely intervention. Choices A, C, and D are not as urgent. A positive Allen test (choice A) assesses collateral circulation and is important for assessing perfusion before arterial cannulation but does not require immediate intervention. Choice C (MAP is 86 mm Hg) falls within the normal range, so it does not indicate an urgent issue. The visibility of the dicrotic notch in the arterial waveform (choice D) is a normal finding and does not require immediate action.
