• C. Penicillin has a narrow spectrum and certain persons are sensitive to it.
• D. Penicillin may be administered without testing the patients for sensitivity to it.

Answer 1

The correct option is D Penicillin may be administered without testing the patients for sensitivity to it.

Penicillin has a narrow spectrum and is effective only against disease caused by various cocci and some gram-positive bacteria. Some people have an allergy to penicillin.

Hence, it is very essential to test the sensitivity of the patient by giving a test dose before giving the full dose.

Therefore, option D is correct.
