Correct Answer is C

Explanation

A. CT of the brain can proceed regardless of atropine administration, as it does not directly affect the assessment of brain stem reflexes.
B. Electroencephalogram (EEG) can also proceed regardless of atropine administration, as it evaluates brain electrical activity rather than brain stem reflexes.
C. Assessment of brain stem reflexes should be postponed until all atropine is excreted and no

longer exerting its effects. Atropine can mask or alter the pupillary response and other brain stem reflexes, such as gag reflex and cough reflex, which are important indicators of neurological function.
D. Pupil response assessment should be postponed until atropine effects have dissipated, as

atropine can cause pupillary dilation, which may interfere with accurate assessment of pupil size and reactivity

Correct Answer is ["0.5"]

Explanation

Given:

Dose required = 35 mg

Concentration of medication = 75 mg/mL Formula:

Volume (mL) = Dose required (mg) / Concentration of medication (mg/mL) Calculation:

Volume (mL) = 35 mg / 75 mg/mL Result:

Volume (mL) = 0.4666667 mL Rounded to the nearest tenth:

Volume (mL) ≈ 0.5 mL
