South University Complete Questions &
Verified A+ Answers
1. What is the primary mechanism of action of metformin in type 2 diabetes
management?
A. Stimulates insulin release from beta cells
B. Decreases hepatic glucose production
C. Inhibits glucose absorption in the intestines
D. Enhances glucagon secretion
Correct Answer: B
Rationale: Metformin primarily reduces gluconeogenesis in the liver and improves
insulin sensitivity, lowering blood glucose levels (NSG 6005 Week 9 focus: Antidiabetic
agents).
2. Which drug is contraindicated in patients with a sulfa allergy?
A. Metformin
B. Sulfamethoxazole
C. Lisinopril
D. Atorvastatin
Correct Answer: B
Rationale: Sulfamethoxazole, a sulfonamide antibiotic, can cause severe allergic
reactions in patients with sulfa allergies (NSG 6005 Week 9 focus: Antibiotic allergies).
3. What is the first-line treatment for hypertension in most patients?
A. Beta-blockers
B. Thiazide diuretics
C. Calcium channel blockers
D. ARBs
Correct Answer: B
Rationale: Thiazide diuretics are recommended as first-line per JNC 8 guidelines due to
their efficacy and cardiovascular risk reduction (NSG 6005 Week 9 focus:
Antihypertensives).
4. Which antibiotic is most likely to cause Clostridium difficile infection?
A. Azithromycin
B. Clindamycin
C. Amoxicillin
D. Doxycycline
Correct Answer: B
Rationale: Clindamycin disrupts gut flora, increasing the risk of C. difficile overgrowth
(NSG 6005 Week 9 focus: Antibiotic adverse effects).
5. What is the primary adverse effect of ACE inhibitors?
A. Hyperkalemia
, 2
B. Dry cough
C. Hypoglycemia
D. Bradycardia
Correct Answer: B
Rationale: ACE inhibitors, like lisinopril, cause a dry cough due to bradykinin
accumulation (NSG 6005 Week 9 focus: Antihypertensive side effects).
6. Which drug requires monitoring for ototoxicity and nephrotoxicity?
A. Gentamicin
B. Amoxicillin
C. Azithromycin
D. Doxycycline
Correct Answer: A
Rationale: Gentamicin, an aminoglycoside, is toxic to the kidneys and inner ear,
requiring serum level monitoring (NSG 6005 Week 9 focus: Antibiotic toxicity).
7. What is the mechanism of action of albuterol in asthma treatment?
A. Inhibits histamine release
B. Stimulates beta-2 adrenergic receptors
C. Blocks leukotriene receptors
D. Enhances mucus production
Correct Answer: B
Rationale: Albuterol, a short-acting beta-2 agonist, causes bronchodilation in acute
asthma (NSG 6005 Week 9 focus: Respiratory medications).
8. Which class of antidepressants is most likely to cause sexual dysfunction?
A. SSRIs
B. MAOIs
C. TCAs
D. SNRIs
Correct Answer: A
Rationale: SSRIs, such as sertraline, commonly cause sexual dysfunction due to
serotonin effects (NSG 6005 Week 9 focus: Psychopharmacology).
9. What is the black box warning for atypical antipsychotics in elderly patients with
dementia?
A. Increased risk of stroke
B. Increased mortality
C. Risk of agranulocytosis
D. Severe weight gain
Correct Answer: B
Rationale: Atypical antipsychotics increase mortality in elderly patients with dementia-
related psychosis (NSG 6005 Week 9 focus: Antipsychotic warnings).
10. Which anticoagulant requires monitoring of INR?
A. Heparin
B. Warfarin
C. Dabigatran
D. Apixaban
Correct Answer: B
, 3
Rationale: Warfarin’s anticoagulant effect is monitored via INR to ensure therapeutic
range (NSG 6005 Week 9 focus: Anticoagulants).
11. What is the primary therapeutic use of montelukast?
A. Acute asthma exacerbation
B. Chronic asthma management
C. Bacterial pneumonia
D. Heart failure
Correct Answer: B
Rationale: Montelukast, a leukotriene receptor antagonist, is used for long-term asthma
control (NSG 6005 Week 9 focus: Respiratory medications).
12. Which drug requires monitoring for agranulocytosis?
A. Clozapine
B. Lisinopril
C. Metformin
D. Atorvastatin
Correct Answer: A
Rationale: Clozapine, an atypical antipsychotic, can cause agranulocytosis, requiring
regular WBC monitoring (NSG 6005 Week 9 focus: Antipsychotic monitoring).
13. What is the mechanism of action of clopidogrel?
A. Inhibits thrombin
B. Blocks ADP receptors on platelets
C. Inhibits factor Xa
D. Enhances fibrin formation
Correct Answer: B
Rationale: Clopidogrel prevents platelet aggregation by inhibiting ADP receptors (NSG
6005 Week 9 focus: Antiplatelets).
14. Which drug is contraindicated in patients with G6PD deficiency?
A. Aspirin
B. Primaquine
C. Metoprolol
D. Albuterol
Correct Answer: B
Rationale: Primaquine causes hemolytic anemia in G6PD-deficient patients due to
oxidative stress (NSG 6005 Week 9 focus: Antimalarials).
15. What is the primary side effect of statins like atorvastatin?
A. Myalgia
B. Hypotension
C. Hypoglycemia
D. Rash
Correct Answer: A
Rationale: Myalgia is the most common side effect of statins due to muscle toxicity
(NSG 6005 Week 9 focus: Lipid-lowering agents).
16. Which antibiotic is safe for use in pregnancy for UTI treatment?
A. Ciprofloxacin
B. Nitrofurantoin
C. Tetracycline
