Q1. Why are combined estrogen-progesterone contraceptives contraindicated in patients with
migraine with aura? [Multiple Choice]
A) Increased risk of stroke
B) Decreased effectiveness of triptans
C) Increased risk of contraceptive failure
D) Increased risk of bleeding
Answer: Increased risk of stroke
Explanation: The contraindication is based on an increased risk of stroke in patients with migraine with aura who
use combined estrogen-progesterone contraceptives. The other choices are not the reason given for avoiding these
products.
,Q2. What is the primary mechanism by which oseltamivir treats influenza? [Multiple Choice]
A) Blocking viral entry into cells
B) Inhibition of viral neuraminidase
C) Inhibition of viral RNA polymerase
D) Disruption of viral protein synthesis
Answer: Inhibition of viral neuraminidase
Explanation: Oseltamivir inhibits viral neuraminidase, an enzyme needed for effective influenza replication and
spread. The source does not identify it as a blocker of viral entry, a protein-synthesis inhibitor, or an RNA-polymerase
inhibitor.
Q3. In the diagram, which mechanism best describes acyclovir's action against viral DNA?
[Multiple Choice]
A) It acts like guanosine, leading to DNA chain termination.
B) It enhances the immune response against viruses.
C) It prevents viral attachment to host cells.
D) It inhibits viral RNA synthesis.
Answer: It acts like guanosine, leading to DNA chain termination.
Explanation: Acyclovir acts as a guanosine analogue. When incorporated into viral DNA, it causes chain termination,
stopping further DNA synthesis.
Q4. Which antifungal is used to treat refractory invasive aspergillosis infections? [Multiple Choice]
A) Anidulafungin
B) Micafungin
C) Caspofungin
D) Oseltamivir
Answer: Caspofungin
, Explanation: Caspofungin is used for refractory invasive aspergillosis. Anidulafungin and micafungin are also
antifungals listed in the source, but they are not identified here as the treatment for this condition; oseltamivir is an
antiviral.
Q5. In the diagram, what makes methenamine effective against bacteria? [Multiple Choice]
A) It releases formaldehyde in acidic conditions, and the formaldehyde is toxic to bacteria.
B) It interferes with bacterial nucleic acid synthesis.
C) It inhibits bacterial cell-wall synthesis.
D) It disrupts bacterial protein synthesis.
Answer: It releases formaldehyde in acidic conditions, and the formaldehyde is toxic to bacteria.
Explanation: In acidic conditions, methenamine releases formaldehyde. The formaldehyde is toxic to bacteria and
produces the antimicrobial effect; the other mechanisms are not the mechanism given for methenamine.
Q6. A bacterial infection is classified as resistant on antimicrobial susceptibility testing. What is
the most appropriate action? [Multiple Choice]
A) Switch to a broad-spectrum antibiotic without testing.
B) Increase the dosage of the current antibiotic.
C) Choose an alternative antibiotic that the bacteria are susceptible to.
D) Continue with the same antibiotic and monitor the patient.
Answer: Choose an alternative antibiotic that the bacteria are susceptible to.
Explanation: A resistant classification means the current antibiotic is not expected to work reliably. Treatment should
therefore be changed to an alternative antibiotic shown by testing to be effective against the bacteria.
Q7. A severe skin infection is resistant to penicillin. Which alternative is appropriate according
to the source? [Multiple Choice]
A) Clindamycin, because it is effective against certain resistant bacteria and treats skin infections.
B) Amoxicillin, due to its broad-spectrum activity.
C) Vancomycin, as it is the first-line treatment for all skin infections.
D) Azithromycin, because it is effective against viral infections.
Answer: Clindamycin, because it is effective against certain resistant bacteria and treats skin infections.
Explanation: Clindamycin is identified as an appropriate alternative because it can treat skin infections caused by
certain resistant bacteria. The other choices rely on claims not supported by the source, and azithromycin is
incorrectly described as an antiviral.
, Q8. In the diagram, which step explains how penicillins disrupt bacterial cell-wall synthesis?
[Multiple Choice]
A) Inhibiting parasite microtubule synthesis and glucose absorption
B) Binding to D-Ala-D-Ala and disrupting the membrane
C) Blocking viral neuraminidase and preventing viral spread
D) Binding to penicillin-binding proteins and inhibiting peptidoglycan cross-linking
Answer: Binding to penicillin-binding proteins and inhibiting peptidoglycan cross-linking
Explanation: Penicillins bind penicillin-binding proteins and inhibit peptidoglycan cross-linking, weakening bacterial
cell-wall synthesis. The other choices describe different drug targets or processes.
Q9. What is one known effect of estrogen on glucose tolerance? [Multiple Choice]
A) Increases blood glucose levels
B) Decreases insulin sensitivity
C) Improves glucose tolerance
D) Has no effect on glucose tolerance
Answer: Improves glucose tolerance
Explanation: The stated effect of estrogen is improved glucose tolerance. The alternatives either describe a different
metabolic effect or deny that estrogen affects glucose tolerance.
Q10. A patient with a urinary tract infection has alkaline urine. What is the likely effect on
methenamine? [Multiple Choice]
A) The efficacy may be reduced due to less formaldehyde production.
B) The efficacy will increase because of enhanced drug solubility.
C) The drug will become more toxic to the patient.
D) The drug will work faster in alkaline urine.
Answer: The efficacy may be reduced due to less formaldehyde production.
Explanation: Methenamine depends on formaldehyde production for its antibacterial effect. Alkaline urine reduces
this production, so the drug may be less effective.
Q11. In the diagram, which effect explains albendazole's antiparasitic action? [Multiple Choice]
A) It inhibits protein synthesis, preventing parasite growth.
B) It inhibits microtubule synthesis, disrupting glucose absorption and reproduction.
C) It disrupts cell membrane integrity, leading to parasite death.
