Which statement by the nurse when explaining the purpose of positive end-expiratory pressure (PEEP) to the patient's caregiver is accurate?

"PEEP prevents the lung air sacs from collapsing during exhalation."

"PEEP allows the breathing machine to deliver 100% 02 to the lungs."

"PEEP will push more air into the lungs during inhalation."

"PEEP will prevent lung damage while the patient is on the ventilator."

Answer and Explanation

The Correct Answer is A

A.   Positive end-expiratory pressure (PEEP) is applied during mechanical ventilation to prevent alveolar collapse at the end of expiration. It helps maintain the patency of the alveoli, improving oxygenation and preventing atelectasis.
B.   While PEEP can improve oxygenation by recruiting collapsed alveoli and increasing functional residual capacity, it does not directly affect the concentration of oxygen delivered by the ventilator. Oxygen concentration is adjusted separately from PEEP settings.
C.   PEEP is applied at the end of expiration to maintain positive pressure in the airways and alveoli, preventing them from collapsing. It does not directly affect the delivery of air during inhalation.
D.   PEEP can help prevent lung damage by maintaining alveolar recruitment and reducing the risk of atelectasis and barotrauma. However, it is not the sole factor in preventing lung damage, and other ventilator settings and strategies also play a role in protecting the lungs.

Correct Answer is D

Explanation

D. Asystole represents the absence of electrical activity in the heart and is not amenable to defibrillation. Therefore, the RRT would continue cardiopulmonary resuscitation (CPR) with chest compressions and may administer medications or other interventions as indicated. This statement provides accurate information to the family about the patient's condition and the actions being taken by the RRT.

A. Defibrillation is not indicated for asystole. Asystole represents a flatline on the cardiac monitor, indicating the absence of electrical activity in the heart. Defibrillation is only effective for certain types of cardiac rhythms, such as ventricular fibrillation or pulseless ventricular tachycardia. Therefore, the RRT would not use defibrillation for a patient in asystole.

B. It does not provide the family with information about the patient's condition or the actions being taken by the RRT. Moreover, excluding the family from the patient's care may cause additional distress and prevent them from being present to support their loved one during a critical situation.

C. Cardiopulmonary resuscitation (CPR) is performed to maintain blood flow and oxygenation to vital organs during cardiac arrest. However, it does not restore normal blood flow or circulation. The goal of CPR is to provide temporary support until advanced interventions can be initiated or until return of spontaneous circulation (ROSC) is achieved.

A. Give PRN lorazepam (Ativan) and cancel the transfer. B. Obtain an order for restraints as needed and transfer the patient. C. Notify the health care provider and postpone the transfer. D. Inform the receiving nurse and then transfer the patient.

Correct Answer is C

Explanation

C. This allows for the patient's condition to be re-evaluated, ensuring that they receive the necessary care and attention before being transferred.

A. Benzodiazepines can cause sedation, cognitive impairment, and delirium, which may worsen the patient's condition. Canceling the transfer without addressing the underlying cause of confusion may delay appropriate management.

B. Restraints can increase agitation, anxiety, and risk of injury, and they do not address the underlying cause of confusion. Restraints should only be considered as a last resort if all other measures to ensure patient safety have been exhausted.

D. This option is not appropriate because transferring the patient without addressing the new-onset confusion could compromise patient safety. It's essential to identify and manage the underlying cause of confusion before transferring the patient to another unit.
