A charge nurse is reviewing the status of patients in the critical care unit. Which patient should the charge nurse notify the organ procurement team to evaluate for possible organ donation?

Choice A reason:

While preparing the gastrointestinal tract for enteral feedings is important, it is not the primary reason for administering famotidine. Famotidine is typically used to reduce gastric acid production, not to prepare the GI tract for feedings.

Choice B reason:

Increasing the motility of the gastrointestinal tract is not the primary function of famotidine. Famotidine is an H2 receptor antagonist that works by decreasing the production of stomach acid.

Choice C reason:

Keeping the gastrointestinal tract functioning normally is a broad statement and does not specifically address the reason for administering famotidine. The drug's role in preventing stress ulcers is more relevant to the patient's current condition.

Choice D reason:

Famotidine is used to prevent stress ulcers, which can occur in critically ill patients, including those on mechanical ventilation. The stress of illness and mechanical ventilation increases the risk of developing gastric ulcers, and famotidine helps reduce this risk by decreasing gastric acid secretion.

Choice A reason:

While an increased respiratory rate can indicate a compensatory response to shock, it does not directly measure tissue perfusion. It suggests the body is attempting to improve oxygen delivery, but it is not a definitive indicator of adequate tissue perfusion.

Choice B reason:

+1 pedal pulses can indicate decreased perfusion to the extremities, but they do not provide comprehensive information about overall tissue perfusion. Peripheral pulses can be weak in shock due to vasoconstriction and poor circulation, but they are not the most reliable indicator of tissue perfusion.

Choice C reason:

Body temperature is not a direct measure of tissue perfusion. While it is important to monitor, changes in temperature can result from various factors and do not specifically reflect the adequacy of tissue perfusion.

Choice D reason:

Urine output greater than 40 cc/hr is a key indicator of adequate tissue perfusion. The kidneys are highly sensitive to changes in perfusion, and adequate urine output suggests that the kidneys are receiving sufficient blood flow to filter and excrete waste products. Monitoring urine output is a standard practice in assessing tissue perfusion and overall fluid balance in shock patients.
