A nurse is assessing a client who has an arteriovenous (AV) graft in the right forearm for hemodialysis access. The nurse auscultates a bruit over the graft area. Which intervention should the nurse implement?

Choice A rationale
Applying oxygen at 10 L via non-rebreather mask and monitoring pulse oximeter is the most important intervention for a patient in the post-anesthesia care unit (PACU) with a heart rate of 140 beats/minute, blood pressure 140/90 mm Hg, and respirations 26 breaths/minute.
These vital signs suggest that the patient may be experiencing hypoxia or respiratory distress, conditions that require immediate intervention.
Choice B rationale
Medicating for pain and monitoring vital signs according to protocol is important in the PACU, but it is not the most critical intervention in this scenario. The patient’s vital signs suggest a possible respiratory issue, which should be addressed immediately.
Choice C rationale
Encouraging the client to splint the incision with a pillow to cough and deep breathe is a common postoperative intervention to promote lung expansion and prevent atelectasis and pneumonia. However, in this scenario, the patient’s vital signs suggest a more immediate respiratory issue that requires prompt intervention.
Choice D rationale
Administering an intravenous fluid bolus as prescribed by the healthcare provider can be an appropriate intervention for certain conditions in the PACU, such as hypotension. However, in this scenario, the patient’s vital signs suggest a possible respiratory issue, which should be addressed immediately.

Choice A rationale
A superficial partial-thickness burn involves the destruction of the epidermis and possibly a portion of the dermis. The description provided does not match this type of burn.
Choice B rationale
A full-thickness burn involves total destruction of the epidermis and dermis, and in some cases, the underlying tissue, muscle, and bone. The description of the burn as severely swollen, with a wound bed that appears brown and yellow, and the patient reporting no pain, is consistent with a full-thickness burn.
Choice C rationale
A deep partial-thickness burn involves the destruction of the epidermis and upper layers of the dermis and injury to the deeper portions of the dermis. The description provided does not match this type of burn.
Choice D rationale
Deep full-thickness burns are a more severe form of full-thickness burns that extend beyond the dermis into deeper tissues. The description provided does not match this type of burn.
