A nurse is checking a client's ventilator settings. The nurse should understand that positive end- expiratory pressure has which of the following purposes?

To deliver a set tidal volume

To provide positive airway pressure during inspiration

To control the rate of ventilations

To prevent alveolar collapse

Answer and Explanation

The Correct Answer is D

Positive end-expiratory pressure (PEEP) is a mode of mechanical ventilation that maintains a positive pressure in the airways at the end of expiration, preventing alveolar collapse and improving oxygenation. PEEP does not affect tidal volume, inspiratory pressure, or ventilation rate, which are determined by other ventilator settings.

Correct Answer is D

Explanation

The client is experiencing signs of an acute hemolytic transfusion reaction, which is a life-threatening emergency. The nurse should stop the infusion immediately and disconnect the blood tubing from the IV catheter to prevent further exposure to the incompatible blood.

A. Contact the client's power of attorney to sign the consent. B. Inform a family member of the need to sign the consent. C. Notify the surgical team that the client is unable to sign the consent. D. Allow the client to sign the consent with an X

Correct Answer is D

Explanation

Allow the client to sign the consent with an X. The client has the right to give informed consent if they understand the procedure and its risks and benefits, even if they cannot read or write. The nurse should witness and document the client's signature with an X and verify their identity and understanding. The other options are not appropriate because they violate the client's autonomy and dignity.
