A nurse is caring for a group of clients on an adult medical-surgical unit.
Which of the following clients should the nurse identify as having the highest risk for aspiration?

Choice A rationale

A blood pressure of 184/92 mm Hg, indicating hypertension, is not a typical immediate sign of an allergic transfusion reaction, which often presents with hypotension due to vasodilation and increased capillary permeability caused by histamine release from mast cells and basophils. This finding might suggest circulatory overload or a pre-existing condition, but not specifically an allergic reaction.

Choice B rationale

Distended jugular veins indicate increased central venous pressure and are characteristic findings of circulatory overload (hypervolemia), which can occur with rapid blood product administration, especially in clients with compromised cardiac or renal function. An allergic reaction's primary manifestation is usually vasodilation and bronchoconstriction, not fluid volume excess.

Choice C rationale

Bilateral flank pain is a cardinal sign associated with an acute hemolytic transfusion reaction (AHTR), which results from the recipient's antibodies destroying donor red blood cells (RBCs), leading to hemoglobinuria and acute tubular necrosis, causing pain due to renal ischemia. Allergic reactions involve mast cell degranulation and histamine release.

Choice D rationale

Generalized urticaria, or hives, is a classic cutaneous manifestation of an allergic (mild hypersensitivity) transfusion reaction. It results from the release of chemical mediators like histamine from sensitized mast cells and basophils, causing local vasodilation, increased capillary permeability, and edema in the dermis, manifesting as itchy, raised welts.

Choice A rationale

Offering the client apple juice is an action to advance the diet, but it is not the initial priority after surgery. Postoperative clients must first demonstrate adequate gastrointestinal motility before introducing any fluids or food to prevent complications like vomiting, aspiration, or abdominal distention due to paralytic ileus, which is common following anesthesia and abdominal manipulation.

Choice B rationale

Elevating the client's head of bed is a crucial safety measure to prevent aspiration when administering food or fluids. However, the first action must be to assess the return of peristalsis because, without bowel sounds, administering clear liquids poses a risk that outweighs positional safety, necessitating the abdominal assessment initially.

Choice C rationale

Ordering a lunch tray represents an advancement to a solid diet, which is inappropriate and contraindicated until the client tolerates clear liquids and has a return of bowel function as evidenced by active peristaltic sounds and passing flatus. Introducing solids prematurely significantly increases the risk of ileus complications.

Choice D rationale

Auscultating the client's abdomen to verify the presence of active bowel sounds is the priority assessment before introducing any oral intake in a postoperative client. The return of peristalsis indicates that the digestive tract has recovered sufficiently from the effects of anesthesia and surgery to safely process fluids, minimizing the risk of ileus and aspiration.
