Bronchial blood supply evaluation

Oximetry

Mixed venous blood gases

Pulmonary blood supply evaluation

Answer and Explanation

The Correct Answer is B

A.   Bronchial blood supply evaluation is not a direct method of monitoring oxygenation status.
B.   Oximetry measures oxygen saturation (SaO2) continuously and non-invasively, providing real-time information about oxygen levels in the blood, which is essential for monitoring a patient with COPD.

C.   Mixed venous blood gases provide information about oxygen extraction by tissues but are not commonly used for continuous monitoring of oxygenation status.
D.   Pulmonary blood supply evaluation may involve various imaging techniques or invasive procedures but is not used for continuous monitoring of oxygenation status.

Correct Answer is D

Explanation

A. While an increasing respiratory rate may indicate respiratory distress, in the context of a closed head injury, decreasing level of consciousness (LOC) is a more concerning trend as it suggests worsening neurological status.
B. A rising heart rate may indicate pain, anxiety, or physiological stress, but it's not as directly related to the severity of a closed head injury.
C. While decreasing blood pressure can be concerning, especially if it indicates hypovolemic shock, in the context of a closed head injury, the primary concern is neurological status.
D. A decreasing LOC suggests worsening neurological function, which can indicate increased intracranial pressure (ICP) or neurological deterioration.
