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.

C. Oral herpes typically presents as cold sores or fever blisters and may not be directly related to the white lesions observed.

D. While oral hygiene is important, the presence of white lesions in James's throat is more likely related to his medical condition and treatment than to dental hygiene habits.

A. Perform a rectal examination B. Refer her to a colonoscopy immediately C. Recommend increasing fiber in her diet D. Prescribe anti-hemorrhoidal medication

Correct Answer is B

Explanation

A. A rectal examination may not detect lesions higher up in the colon

B. Rectal bleeding and change in bowel habits are red flags for colorectal cancer, especially in people over 50 years old. A colonoscopy is the gold standard for diagnosing colorectal cancer and other conditions affecting the colon and rectum.
C. While increasing fiber may be beneficial for overall bowel health, it is not the immediate action to take when rectal bleeding and changes in bowel habits are reported.
D. Prescribing medication without a proper evaluation could mask underlying issues and is not the appropriate initial step.
