A nurse is caring for a patient with a nasogastric (NG) tube and tests the pH of the secretions to verify correct placement of the tube.
What pH reading should the nurse expect?

Choice A rationale

A black pressure ulcer indicates necrotic tissue, which often requires surgical debridement.

Choice B rationale

Increased drainage from the wound is not typically associated with a black pressure ulcer.

Choice C rationale

While documenting the wound status daily is part of wound care, it is not a specific event anticipated when planning care for a patient with a black pressure ulcer.

Choice D rationale

Increased monitoring of the wound condition is part of wound care, but it is not a specific event anticipated when planning care for a patient with a black pressure ulcer.

Choice A rationale

Excessive thirst and urination are symptoms of hyperglycemia, not hypoglycemia. Hyperglycemia could occur if the TPN solution was infusing too quickly, but it would not be a result of the infusion pump not working.

Choice B rationale

Shakiness and diaphoresis are manifestations of hypoglycemia. When a sudden interruption in the infusion of TPN occurs, the patient is at risk for hypoglycemia.

Choice C rationale

Fever and chills are symptoms of infection, not a direct result of the TPN infusion stopping.

Choice D rationale

Hypertension and crackles in the lungs are signs of fluid overload, not hypoglycemia. These symptoms would not be expected if the TPN infusion stopped.
