A nurse is instructing a nursing student on performing pupillary checks on a patient with a possible head injury. Which statement indicates that the nursing student understands the concept?
"When I shine a light into the patient's eyes, the pupils should constrict."
"It is normal for the pupils to react sluggishly to light."
"When I shine a light into the patient's eyes, the pupils should dilate
"Pupil checks should be performed with the room lights on."
The Correct Answer is A
A. The normal response to light in the eye is pupil constriction. This indicates that the optic and oculomotor nerves are functioning properly.
B. While a sluggish reaction can occur in some individuals, a noticeable sluggish response could indicate neurological issues, especially in a head injury.
C. Pupils should constrict in response to light, not dilate, unless there is a significant neurological impairment.
D. Pupil checks should ideally be performed in dim lighting for better visibility of pupillary reactions, not with the room lights on.

Explanation
A. Temperature monitoring is important but not a top priority when a patient is receiving opiates unless there is suspicion of infection.
B. Pulse monitoring is also important but does not immediately indicate issues with opiate use.
C. Blood pressure is influenced by opiate use, but the primary concern is respiratory function due to the risk of respiratory depression.
D. Respirations should be closely monitored because opiates can significantly depress the respiratory system, leading to hypoventilation or respiratory arrest, which is the most critical risk.
Correct Answer is C
Explanation
A. Wrapping the cuff snugly around the arm is important for an accurate reading. The cuff should be snug but not tight to avoid false readings.
B. Positioning the cuff bladder over the brachial artery ensures the correct placement for accurate measurement.
C. Placing the arm above the level of the heart can lead to a falsely low blood pressure reading. The arm should be at heart level for an accurate measurement.
