1. A 68-year-old male with a history of HFrEF (LVEF 30%) presents for a follow-up. He is
currently on Lisinopril and Carvedilol. Which finding would most urgently require the addition
of an Aldosterone Antagonist like Spironolactone?
A. Persistent NYHA Class II symptoms despite current therapy
B. Potassium level of 5.2 mEq/L
C. Serum creatinine of 2.8 mg/dL
D. Occasional pedal edema late in the day
Answer: A
Rationale: Aldosterone antagonists are indicated for patients with HFrEF who remain
symptomatic despite optimal doses of ACE inhibitors and beta-blockers. Clinical trials like
RALES and EMPHASIS-HF demonstrate significant reduction in mortality and
hospitalization for these patients. However, they must be avoided if potassium is above 5.0
or creatinine is significantly elevated, making option B the only valid clinical indication
here.
,2. When evaluating a patient for Chronic Obstructive Pulmonary Disease (COPD), which
spirometric value is considered the gold standard for confirming persistent airflow limitation?
A. Post-bronchodilator FEV1/FVC ratio < 0.70
B. Pre-bronchodilator FEV1/FVC ratio < 0.80
C. Peak Expiratory Flow Rate (PEFR) variation > 20%
D. Forced Vital Capacity (FVC) below 50% predicted
Answer: A
Rationale: According to GOLD guidelines, a post-bronchodilator FEV1/FVC ratio of less
than 0.70 is required to confirm the diagnosis of COPD. This measurement indicates that
the airflow obstruction is not fully reversible, which distinguishes it from asthma.
Advanced practice nurses must ensure that spirometry is performed correctly to avoid
misdiagnosis and inappropriate treatment initiation.
3. An 45-year-old female presents with symptoms of hypothyroidism. Laboratory results
show a high TSH and a low Free T4. What is the most likely underlying etiology in a developed
nation?
A. Iodine deficiency
B. Pituitary adenoma
C. Hashimoto’s thyroiditis
D. Graves’ disease
,Answer: C
Rationale: Hashimoto’s thyroiditis is the most common cause of primary hypothyroidism
in iodine-sufficient regions due to autoimmune destruction of the thyroid gland. The high
TSH reflects the pituitary’s attempt to stimulate the failing gland, while the low Free T4
confirms the deficiency. Management typically involves lifelong Levothyroxine replacement
therapy with titration based on TSH levels.
4. A patient with Type 2 Diabetes is currently taking Metformin 1000mg BID but has an A1C of
8.2%. The patient has established Atherosclerotic Cardiovascular Disease (ASCVD). Which
medication class should be prioritized for addition?
A. Sulfonylureas
B. DPP-4 Inhibitors
C. Basal Insulin
D. GLP-1 Receptor Agonists with proven CVD benefit
Answer: D
Rationale: Current ADA guidelines recommend GLP-1 receptor agonists or SGLT2
inhibitors with proven cardiovascular benefit for patients with established ASCVD,
regardless of A1C. These agents have been shown to reduce major adverse cardiovascular
events (MACE) in clinical trials. Sulfonylureas are generally avoided in this context due to
hypoglycemia risks and lack of cardiovascular protection.
, 5. Which of the following physical examination findings is most specific for a diagnosis of
Acute Appendicitis?
A. Murphy’s sign
B. Cullen’s sign
C. McBurney’s point tenderness
D. Grey Turner’s sign
Answer: C
Rationale: McBurney’s point tenderness, located one-third of the distance from the
anterior superior iliac spine to the umbilicus, is a classic sign of localized peritonitis due to
appendicitis. Murphy’s sign is associated with cholecystitis, while Cullen’s and Grey
Turner’s signs are associated with hemorrhagic pancreatitis. Accurate physical assessment
is vital for determining the necessity of surgical intervention.
6. In the management of Community-Acquired Pneumonia (CAP) in a previously healthy
outpatient with no antibiotic use in the last 3 months, which is the preferred first-line
treatment?
A. Vancomycin
B. Ciprofloxacin
C. Amoxicillin or Doxycycline
D. Metronidazole
