NSG 533 Exam 1
Question 1
A patient is diagnosed with Helicobacter pylori infection. Which regimen represents
the standard clarithromycin triple therapy?
A) Clarithromycin 500mg BID + amoxicillin 1g BID + PPI BID
B) Clarithromycin 500mg BID + metronidazole 500mg TID + PPI BID
C) Amoxicillin 1g BID + clarithromycin 500mg BID + metronidazole 500mg BID + PPI BID
D) Both A and B are acceptable clarithromycin triple therapy regimens
Correct Answer: D
Rationale: Clarithromycin triple therapy consists of clarithromycin 500mg BID plus a PPI
BID, with EITHER amoxicillin 1g BID OR metronidazole 500mg TID as the third agent.
Option A represents the amoxicillin-based regimen; Option B represents the
metronidazole-based regimen (used in penicillin-allergic patients or areas with high
macrolide resistance). Option C describes a nonbismuth-based quadruple therapy, not
triple therapy.
Question 2
Which of the following describes the nonbismuth-based quadruple therapy for H.
pylori? (Select all that apply)
,A) Amoxicillin 1g BID
B) Clarithromycin 500mg BID
C) Metronidazole 500mg BID
D) PPI BID
E) Bismuth subsalicylate 300mg QID
Correct Answer: A, B, C, D
Rationale: Nonbismuth-based quadruple therapy (also called concomitant therapy)
includes four medications: amoxicillin 1g BID, clarithromycin 500mg BID, metronidazole
500mg BID, and a PPI BID. This regimen does NOT include bismuth subsalicylate—that is
reserved for bismuth quadruple therapy. The quadruple approach is used when
clarithromycin resistance is a concern or as first-line in some guidelines.
Question 3
A patient with a documented penicillin allergy requires H. pylori treatment. Which
alternate regimen should be recommended?
A) Continue standard clarithromycin triple therapy with amoxicillin; penicillin allergy is
rarely true
B) Bismuth quadruple therapy: bismuth subsalicylate 300mg QID + metronidazole 250–
500mg QID + tetracycline 500mg QID + PPI BID
C) Nonbismuth-based quadruple therapy with amoxicillin substituted for azithromycin
D) PPI monotherapy for 14 days
Correct Answer: B
Rationale: In patients with true penicillin allergy, bismuth quadruple therapy is the
recommended alternative. This regimen includes bismuth subsalicylate 300mg QID,
metronidazole 250–500mg QID, tetracycline 500mg QID, and a PPI BID. Tetracycline is used
instead of amoxicillin, and the bismuth provides additional mucosal protection and
antimicrobial activity. Option D (PPI monotherapy) would not eradicate H. pylori.
Question 4
Which proton pump inhibitor (PPI) is recommended as the MOST efficacious for
treating moderate to severe GERD?
A) Omeprazole
B) Esomeprazole
,C) Pantoprazole
D) All PPIs have similar efficacy
Correct Answer: D
Rationale: All PPIs have similar efficacy in reducing gastric acid secretion and healing
erosive esophagitis. They provide significant acid suppression and greatest relief of
symptoms, especially in moderate to severe GERD. While individual PPIs may vary slightly
in pharmacokinetics (e.g., esomeprazole is the S-isomer of omeprazole), clinical outcomes
are generally comparable. Selection is often based on drug interactions, cost, and formulary
availability rather than intrinsic efficacy.
Question 5
Which lifestyle modifications should be recommended for a patient with
gastroesophageal reflux disease (GERD)? (Select all that apply)
A) Eating smaller meals
B) Losing weight if overweight
C) Elevating the head of the bed (HOB) at night
D) Smoking cessation
E) Avoiding alcohol
F) Increasing caffeine intake
Correct Answer: A, B, C, D, E
Rationale: Key lifestyle modifications for GERD include: eating smaller meals (reduces
gastric distension and transient LES relaxations), weight loss (decreases intra-abdominal
pressure), elevating HOB 6–8 inches (uses gravity to reduce nocturnal reflux), smoking
cessation (nicotine decreases LES tone), and avoiding alcohol (relaxes LES and irritates
mucosa). Caffeine can also decrease LES tone and should be avoided, not increased.
Question 6
Which over-the-counter (OTC) medication class is used to treat diarrhea by adding
bulk to the stool?
A) Antimotility agents
B) Antisecretory agents
C) Bulk-forming agents
D) Probiotics
,Correct Answer: C
Rationale: Bulk-forming agents such as calcium polycarbophil and psyllium absorb water
and add bulk to stool, which can help regulate bowel movements in both diarrhea and
constipation. They work by increasing stool viscosity and transit time. These are generally
safe for long-term use and are first-line for functional diarrhea.
Question 7
Which OTC medications are classified as antimotility agents for diarrhea treatment?
(Select all that apply)
A) Loperamide
B) Diphenoxylate
C) Bismuth subsalicylate
D) Psyllium
Correct Answer: A, B
Rationale: Antimotility agents reduce intestinal motility and prolong transit time, allowing
more water absorption. Loperamide (Imodium) and diphenoxylate (Lomotil) are the
primary OTC antimotility agents. Bismuth subsalicylate is an antisecretory/anti-
inflammatory agent. Psyllium is a bulk-forming agent. Caution: Antimotility agents should
NOT be used in infectious diarrhea (especially C. difficile or dysentery) as they can worsen
the condition by trapping the pathogen.
Question 8
Bismuth subsalicylate is classified as which type of OTC antidiarrheal agent?
A) Bulk-forming agent
B) Antimotility agent
C) Antisecretory agent
D) Probiotic
Correct Answer: C
Rationale: Bismuth subsalicylate (Pepto-Bismol) is an antisecretory agent that reduces
fluid secretion into the intestinal lumen. It also has antimicrobial properties (effective
against H. pylori and some enteropathogens) and anti-inflammatory effects. It coats the
gastric and intestinal mucosa, providing symptomatic relief. The subsalicylate component is

Question 1
A 58-year-old woman with postmenopausal osteoporosis presents with heartburn.
She has been self-treating with OTC calcium carbonate (Tums) for 6 weeks with
minimal relief. Which statement about her current therapy and next steps is MOST
accurate?
A) Calcium carbonate is appropriate long-term therapy; she should increase the dose
B) She should switch to an H2RA because antacids are only for PRN use and calcium
carbonate carries risk of kidney stones and hypercalcemia
C) An antacid trial should continue for 8 weeks before considering other agents
D) She should immediately undergo endoscopy because antacids failed
Correct Answer: B
Rationale: Antacids (calcium carbonate) provide rapid, short-duration relief and are
appropriate for PRN use only. Long-term use of calcium-containing antacids risks
hypercalcemia, constipation, and kidney stones. Aluminum antacids cause constipation;
magnesium antacids cause diarrhea. For persistent symptoms beyond 2 weeks, escalation
to H2RAs or PPIs is indicated. Endoscopy is reserved for alarm symptoms (dysphagia,
odynophagia, weight loss, GI bleed, anemia)—not simply treatment failure with antacids.
Question 2
A patient with type 2 diabetes and established ASCVD needs an add-on to metformin.
Which agent is PREFERRED for cardiovascular risk reduction?
A) Glipizide
B) Pioglitazone
C) GLP-1 receptor agonist or SGLT2 inhibitor
D) Acarbose
Correct Answer: C
Rationale: For patients with T2DM and ASCVD, guidelines prefer GLP-1 RAs (liraglutide,
semaglutide, dulaglutide) or SGLT2 inhibitors (empagliflozin, canagliflozin) as add-on
,therapy due to demonstrated cardiovascular benefit (reduced MACE, CV death, heart
failure). Glipizide (sulfonylurea) causes hypoglycemia and weight gain with no CV benefit.
Pioglitazone (TZD) causes weight gain, edema, and heart failure exacerbation. Acarbose has
minimal effect and poor GI tolerability.
Question 3
Which medications can CAUSE or WORSEN erectile dysfunction (ED)? (Select all that
apply)
A) Thiazide diuretics
B) Nonselective beta-blockers (e.g., propranolol)
C) SSRIs and SNRIs
D) Opioids
E) 5-alpha reductase inhibitors
Correct Answer: A, B, C, D, E
Rationale: The mnemonic "SAD BB-COP" identifies ED-causing medications: SSRIs/SNRIs,
Antipsychotics, Diuretics (thiazides); Beta-blockers (nonselective > selective); Centrally
acting antihypertensives (clonidine, methyldopa), Opioids, Prostate cancer therapies
(androgen deprivation). 5-ARIs (finasteride, dutasteride) also cause decreased libido and
ED. Before prescribing PDE-5 inhibitors, ALWAYS review for offending medications and
substitute when possible (e.g., thiazide → ACE/ARB; nonselective BB → cardioselective BB
or ACE; SSRI → bupropion).
Question 4
A patient on clopidogrel for recent coronary stent placement develops GERD with
erosive esophagitis. Which PPI is the PREFERRED choice?
A) Omeprazole
B) Esomeprazole
C) Pantoprazole
D) All PPIs are equally safe with clopidogrel
Correct Answer: C
Rationale: Pantoprazole is preferred in patients on clopidogrel because it has the fewest
CYP2C19 interactions. Omeprazole and esomeprazole inhibit CYP2C19, which is required to
convert clopidogrel (a prodrug) to its active metabolite. This interaction can reduce
, clopidogrel's antiplatelet efficacy and increase cardiovascular event risk. Pantoprazole is
the safest PPI choice in this scenario.
Question 5
A 68-year-old man with coronary artery disease is newly diagnosed with
hypothyroidism (TSH 12.5, free T4 low). What is the MOST appropriate approach to
initiating levothyroxine?
A) Start full replacement dose (1.6 mcg/kg/day) immediately
B) Start low dose (12.5–25 mcg/day) and titrate slowly every 6–8 weeks
C) Start liothyronine (T3) for faster symptom relief
D) Delay treatment until cardiac status is optimized
Correct Answer: B
Rationale: In elderly patients and those with cardiac disease, levothyroxine must be
started LOW (12.5–25 mcg/day) and titrated slowly every 6–8 weeks based on TSH. Rapid
normalization can precipitate angina, atrial fibrillation, or MI due to increased myocardial
oxygen demand, heart rate, and contractility. The longer hypothyroidism has been present,
the more the body has adapted to a low-thyroid state; rapid replacement overwhelms these
adaptive mechanisms. Liothyronine is not preferred due to short half-life and cardiac risks.
Question 6
Which statement about amiodarone-induced thyroid dysfunction is MOST accurate?
A) Amiodarone contains minimal iodine and rarely affects thyroid function
B) Amiodarone 200mg supplies 75mg iodine; thyroid issues usually appear within 6
months
C) Hypothyroidism is more common in iodine-deficient regions
D) TSH should be checked only if symptoms develop
Correct Answer: B
Rationale: Amiodarone is 37% iodine by weight; 200mg contains ~75mg iodine with
~6mg free iodine released (20–40× daily requirement). This iodine load causes both
hypothyroidism (Wolff-Chaikoff effect, more common in iodine-SUFFICIENT regions and
those with underlying thyroid disease) and hyperthyroidism (Jod-Basedow phenomenon,
more common in iodine-deficient regions). Monitoring: TSH, free T4, and free T3 at
baseline and 3 months; then TSH every 3–6 months. Thyroid issues typically appear within
6 months but can occur later.
