Correct Answer is B
Explanation
A. Assist the patient into the prone position: The prone position (lying face down) is not suitable for eye irrigation and may make the procedure more difficult.
B. Position the patient with their head turned toward the affected side: Turning the patient’s head toward the affected side helps to ensure that the irrigation fluid drains away from the unaffected eye and is more effective in flushing out debris or irritants.
C. Flush the patient's eye from the outer to the inner canthus: Flushing from the inner to the outer canthus is preferred to prevent contaminating the unaffected eye and to ensure effective irrigation.
D. Instruct the patient to hold their affected eye open: The patient should be instructed to keep their eye open, but it is more important to ensure proper positioning and technique during the irrigation.
Correct Answer is B
Explanation
A. Capillary blood: Capillary blood can be used in some cases, especially in infants, but it is less accurate than arterial blood for measuring blood pH and gases.
B. Arterial blood: Arterial blood is the correct sample for measuring blood pH and gases (such as oxygen and carbon dioxide levels) because it reflects the gas exchange occurring in the lungs.
C. Venous blood: Venous blood is not typically used for measuring blood gases as it does not accurately reflect the oxygenation status of the body.
D. Cerebrospinal fluid: Cerebrospinal fluid is not used for measuring blood pH and gases; it is typically analyzed for conditions affecting the brain and spinal cord.
