A nurse is reinforcing teaching with a client who is scheduled to have a colonoscopy in 1 week. Which of the following client statements indicates an understanding of the teaching?

Rationale:

A. Deliver 2 L of oxygen via partial nonrebreather mask: While oxygen can support airway function, it does not address the underlying cause of anaphylaxis. Airway closure due to an allergic reaction requires immediate pharmacologic intervention, not just oxygen delivery.

B. Give epinephrine intramuscularly: Epinephrine is the first-line treatment for anaphylaxis. It counteracts bronchoconstriction, airway edema, and hypotension by stimulating alpha and beta receptors, and should be administered immediately when signs of airway compromise are present.

C. Administer diazepam PO: Diazepam is used for anxiety or seizures, not for acute allergic reactions. It has no effect on reversing airway swelling or bronchospasm and would delay the appropriate emergency treatment needed in this situation.

D. Notify the radiology department: Contacting the radiology department is not relevant or urgent in this scenario. The client is experiencing a life-threatening reaction that requires immediate medical intervention, not communication with non-emergency services.

Rationale:

A. Instruct the client to lie supine with his knees flexed: Flexing the knees reduces tension on the abdominal wall and helps prevent further protrusion of abdominal contents. This position is critical for stabilizing the evisceration while awaiting surgical intervention.

B. Cover the wound with a dry sterile dressing: Using a dry dressing can cause the exposed organs to dry out and adhere to the material, increasing the risk of tissue damage. A moist sterile dressing is needed to protect and preserve the protruding tissues.

C. Position the client in semi-Fowler's position: Elevating the head of the bed increases intra-abdominal pressure and can worsen evisceration. This position should be avoided to prevent strain on the open surgical site.

D. Cover the wound with a transparent dressing: Transparent dressings are not suitable for eviscerations because they do not provide adequate moisture or protection for exposed organs. A sterile saline-moistened dressing is required to maintain tissue integrity.
