Rationale (NUR6130 Exam 3) | William

1. A 68-year-old male presents with Heart Failure with reduced Ejection Fraction (HFrEF) of
30%. Which class of medication is essential for reducing long-term mortality in this patient?
A. Loop Diuretics
B. Digoxin
C. Calcium Channel Blockers
D. Beta-Blockers
Answer: D
Rationale: Beta-blockers are a primary component of guideline-directed medical therapy
for HFrEF because they inhibit the deleterious effects of the sympathetic nervous system
on the heart. Clinical trials have consistently demonstrated that they reduce mortality and
hospitalizations in patients with chronic heart failure. In contrast, loop diuretics manage
symptoms of volume overload but have not been shown to reduce long-term mortality.
2. A patient with Type 2 Diabetes Mellitus has a current A1C of 8.2% despite maximal doses
of Metformin. The patient has a history of atherosclerotic cardiovascular disease (ASCVD).
What is the most appropriate next step in pharmacotherapy?
A. DPP-4 Inhibitor
,B. Basal Insulin
C. Sulfonylurea
D. GLP-1 Receptor Agonist
Answer: D
Rationale: ADA guidelines recommend GLP-1 receptor agonists with proven
cardiovascular benefit for patients with T2DM and established ASCVD regardless of A1C.
These agents provide not only glucose-lowering effects but also significant reduction in
major adverse cardiovascular events. Sulfonylureas are generally avoided as second-line
therapy in this context due to hypoglycemia risk and lack of cardiovascular protection.
3. According to the GOLD criteria, which treatment is recommended for a patient in Group D
(highly symptomatic, high risk of exacerbation)?
A. SABA as needed only
B. LAMA + LABA combination
C. LAMA monotherapy
D. ICS monotherapy
Answer: B
Rationale: For patients in Group D, the GOLD guidelines recommend starting therapy with
a LAMA + LABA combination to maximize bronchodilation and reduce the risk of
exacerbations. Inhaled Corticosteroids (ICS) should not be used as monotherapy in COPD
,due to limited efficacy and increased pneumonia risk. Escalation to triple therapy
(LAMA+LABA+ICS) is considered if the patient continues to experience exacerbations while
on dual bronchodilator therapy.
4. An 82-year-old female presents with confusion, lethargy, and a sodium level of 122 mEq/L.
What is the most critical risk associated with overly rapid correction of chronic
hyponatremia?
A. Osmotic Demyelination Syndrome
B. Acute Tubular Necrosis
C. Cerebral Edema
D. Pulmonary Embolism
Answer: A
Rationale: Osmotic Demyelination Syndrome (formerly Central Pontine Myelinolysis) is a
devastating neurologic condition caused by rapid shift of water out of brain cells. This
occurs when sodium levels are raised too quickly in a patient whose brain has already
adapted to a low-sodium environment. Sodium correction should generally not exceed 8-10
mEq/L in a 24-hour period to avoid this complication.
5. A 55-year-old male with Chronic Kidney Disease (CKD) has a GFR of 42 mL/min/1.73m².
Which stage of CKD does this represent?
A. Stage 2
B. Stage 3a
, C. Stage 4
D. Stage 3b
Answer: D
Rationale: CKD Stage 3 is divided into 3a (GFR 45-59) and 3b (GFR 30-44). A GFR of 42
falls into the Stage 3b category, indicating moderate to severe kidney damage. Accurate
staging is vital for determining the frequency of monitoring and the management of
complications such as anemia and bone mineral disease.
6. A patient presents with a TSH of 0.1 mIU/L and an elevated Free T4. The physical exam
reveals a diffuse, non-tender goiter and exophthalmos. What is the most likely diagnosis?
A. Hashimoto’s Thyroiditis
B. Graves’ Disease
C. Subacute Thyroiditis
D. Toxic Multinodular Goiter
Answer: B
Rationale: Graves’ Disease is an autoimmune condition characterized by hyperthyroidism
and is the most common cause of thyrotoxicosis. The presence of exophthalmos (bulging
eyes) and a diffuse goiter are classic clinical markers that differentiate it from other causes
of hyperthyroidism. Laboratory findings typically show a suppressed TSH and elevated
thyroid hormones due to stimulating antibodies.
