A nurse is caring for a client who is receiving one unit of packed red blood cells (RBCs) due to intraoperative blood loss.
The client reports chills and back pain, and their blood pressure is 80/64 mm Hg. What should be the nurse’s first action?

Choice A rationale
While having a room within view of the nurses’ station can be beneficial for monitoring the patient, it does not specifically address the needs of a patient with active tuberculosis.
Choice B rationale
Placing a patient with active tuberculosis in a room with another non-surgical patient could potentially expose the other patient to the disease. Tuberculosis is an airborne disease and can easily spread to others in close proximity.
Choice C rationale
A room with air exhaust directly to the outdoor environment is the most appropriate choice for a patient with active tuberculosis. This type of room, known as a negative pressure room, helps prevent the spread of airborne diseases like tuberculosis. The air in the room is vented outside, reducing the risk of the disease spreading to other areas of the hospital.
Choice D rationale
While the ICU is equipped to handle severe and critical cases, a patient with active tuberculosis does not necessarily need to be in the ICU unless they are critically ill. Moreover, placing them in the ICU could potentially expose other critically ill patients to tuberculosis.

Choice A rationale
While a nasogastric tube can be used to determine the pH of gastric secretions, this is not typically the primary reason for its use in the treatment of pyloric obstruction.
Choice B rationale
While nasogastric tubes can be used to supply nutrients via tube feedings, this is not typically the primary reason for its use in the treatment of pyloric obstruction. In the case of pyloric obstruction, the focus is usually on relieving the obstruction rather than on feeding.
Choice C rationale
While nasogastric tubes can be used to administer medications, this is not typically the primary reason for its use in the treatment of pyloric obstruction.
Choice D rationale
The primary reason for the use of a nasogastric tube in the treatment of pyloric obstruction is to decompress the stomach. Pyloric obstruction can cause a buildup of gastric contents above the level of the obstruction, leading to symptoms such as nausea and vomiting. A nasogastric tube can be used to remove these contents and relieve symptoms.
