Pharmacology Review Questions - Chapters 7-12

1. What is the primary function of ribosomes in the cell?

Correct Answer: C - Ribosomes synthesize proteins by translating mRNA.

2. Arrange the following steps in the function of the sodium-potassium pump to maintain a negative charge inside the cell (use the format "1234" for 1→2→3→4):

  1. ATP provides energy by phosphorylating the pump.
  2. Sodium ions move out of the cell.
  3. Potassium ions move into the cell.
  4. The pump returns to its original shape.

Enter the correct sequence (e.g., "1234"):

Correct Sequence: 1 → 2 → 3 → 4

3. Which of the following scenarios indicate the use of combination therapy in infection treatment? (Select all that apply)

Correct Answers: A, C, D

4. Match each scenario with the correct anti-infective prophylaxis indication:

A. Surgical patient receiving cefazolin pre-op

B. Patient exposed to tuberculosis

C. HIV+ patient taking TMP-SMX

D. Immunocompromised chemotherapy patient

Correct Matches:
A → Prevention of post-op infections
B → Prevention of TB development
C → Prevention of Pneumocystis pneumonia
D → Prevention of opportunistic infections

5. A bacteriostatic antibiotic works by ______ bacterial growth rather than directly killing bacteria.

Correct Answer: "inhibiting" (or similar form)

6. Which antibiotic class is known for inhibiting bacterial protein synthesis?

Correct Answer: C - Macrolides bind to the 50S subunit to inhibit protein synthesis.

10. What is the most common intestinal parasite in the U.S.?

Correct Answer: B - Giardia lamblia

11. Arrange the correct sequence for malaria treatment using combination therapy (use format "1234" for 1→2→3→4):

  1. Identify the Plasmodium species.
  2. Initiate chloroquine if sensitive.
  3. Add primaquine if hypnozoites are present.
  4. Monitor for treatment efficacy.

Enter the correct sequence (e.g., "1234"):

Correct Sequence: 1 → 2 → 3 → 4
