- D. 13
Correct Answer: A
Rationale: A GCS score of 7 or less indicates a comatose state, while a score of 15 indicates full alertness. Scores of 9, 11, and 13 suggest varying degrees of neurological impairment but not coma. Recognizing a comatose state is critical for patient management.

Which type of drug could be used to treat asthma by opening airways wider?
- A. sympatholytic drug
- B. sympathomimetic drug
- C. anticholinergic drug
- D. parasympathomimetic drug
Correct Answer: B
Rationale: The correct answer is B: sympathomimetic drug. Sympathomimetic drugs stimulate the sympathetic nervous system, leading to bronchodilation and opening of airways wider, which is beneficial in treating asthma.
A: Sympatholytic drugs inhibit the sympathetic nervous system and would not be effective in widening airways in asthma treatment.
C: Anticholinergic drugs block the action of acetylcholine, which can cause bronchoconstriction and are not used to widen airways in asthma.
D: Parasympathomimetic drugs stimulate the parasympathetic nervous system, leading to bronchoconstriction and are not used to treat asthma by opening airways wider.
