The pharmacology instructor is discussing antimicrobials with the nursing class. What would the instructor tell the students about the mechanism of action of antimicrobials? (Select all that apply).

A) Preventing cell division
B) Causing cell death
C) Inhibiting cell wall synthesis
D) Causing leakage of cell wall allowing fluid to leak in
E) Inhibiting synthesis of ribonucleic acid (RNA)

Question 2

The nurse, working in the emergency department, receives a patient following a motor vehicle accident whose medical history is unknown with a blood glucose level of 325 mg/dL.

What rationale does the nurse provide explaining this elevated blood glucose level? A) The patient's accident was caused by diabetic ketoacidosis (DKA).
B) The patient has not been taking the antidiabetic agent as prescribed.
C) The patient most likely just finished a meal.
D) The stress reaction caused an increase in blood sugar.

Answer to Question 1

A, B, C
Feedback:
Sites of cellular action of carbapenems, ketolides, lincosamides, aztreonam, penicillins, sulfonamides, tetracyclines, and antimycobacterials. Carbapenems, ketolides, and lincosamides change protein function and prevent cell division or cause cell death. Aztreonam alters cell membranes to allow leakage of intracellular substances and causes cell death; it does not cause leakage of fluid into the cell. Penicillins prevent bacteria from building their cells during division. Sulfonamides inhibit folic acid synthesis for RNA and deoxyribonucleic acid production but does not inhibit RNA synthesis

Answer to Question 2

D
Feedback:
The stress reaction elevates the blood glucose concentration above the normal range. In severe stress situations, the blood glucose level can be very high (300 to 400 mg/dL). The body uses that energy to fight the insult or flee from the stressor. The patient may or may not be diabetic so this is not DKA, not an indication of medication noncompliance, and not an indication the patient had just eaten.
