Question 1
A 45-year-old patient presents to the emergency department with
acute chest pain that radiates to the left shoulder. The
electrocardiogram (ECG) reveals ST-segment elevation in leads
II, III, and aVF. Which coronary artery is most likely occluded?
A) Left anterior descending (LAD) artery
B) Left circumflex (LCx) artery
C) Right coronary artery (RCA)
D) Posterior descending artery (PDA)
,Correct Answer: C) Right coronary artery (RCA)
Rationale: ST-segment elevation in leads II, III, and aVF
indicates an acute inferior wall myocardial infarction (MI).
The right coronary artery (RCA) supplies the inferior wall of
the myocardium in the vast majority of patients. Occlusion of
the LAD typically presents with changes in the anterior leads
(V1-V4), while the LCx supplies the lateral wall (leads I, aVL,
V5, V6).
Question 2
A healthcare provider prescribes a continuous intravenous
infusion of heparin for a patient diagnosed with a deep vein
thrombosis (DVT). Which laboratory parameter must the nurse
monitor closely to evaluate the therapeutic effectiveness of this
medication?
A) Prothrombin time (PT)
B) Activated partial thromboplastin time (aPTT)
C) International Normalized Ratio (INR)
D) Platelet count
Correct Answer: B) Activated partial thromboplastin time (aPTT)
Rationale: The therapeutic effect of unfractionated heparin is
monitored using the activated partial thromboplastin time
(aPTT). Prothrombin time (PT) and International Normalized
Ratio (INR) are utilized to monitor oral anticoagulant therapy,
such as warfarin. While platelet counts are monitored to
screen for heparin-induced thrombocytopenia (HIT), they do
not measure the drug's therapeutic anticoagulant
effectiveness.
,Question 3
During a psychiatric assessment, a client exhibits rapid shifting
from one topic to an unrelated topic without any logical connection
between the thoughts, though the sentence structure remains
intact. The nurse documents this formal thought disorder as:
A) Flight of ideas
B) Loose associations
C) Neologisms
D) Word salad
Correct Answer: B) Loose associations
Rationale: Loose associations (derailment) involve a lack of
logical connection between progressive thoughts or ideas.
Flight of ideas involves rapid shifting, but there is usually a
fragile, recognizable connection or play on words between
them. Neologisms are entirely invented words, and word
salad represents a completely incoherent mixture of words
lacking proper grammatical structure.
Question 4
A patient with chronic kidney disease (CKD) is prescribed epoetin
alfa. Which physiological outcome demonstrates that the
medication is achieving its intended therapeutic objective?
A) Decreased blood urea nitrogen (BUN) levels
B) Increased serum calcium levels
C) Increased hematocrit and hemoglobin levels
D) Decreased serum potassium levels
Correct Answer: C) Increased hematocrit and hemoglobin levels
Rationale: Epoetin alfa is a synthetic form of erythropoietin, a
hormone produced by the kidneys that stimulates the bone
, marrow to produce red blood cells. It is prescribed to treat
anemia associated with chronic kidney disease. Therefore,
its efficacy is determined by an increase in hemoglobin and
hematocrit values, not by changing metabolic waste
products or electrolyte balances.
Question 5
An infant is admitted with suspected intussusception. Which
clinical manifestation is considered the hallmark physical finding
associated with this condition?
A) Projectile, non-bilious vomiting
B) Ribbon-like, foul-smelling stools
C) Currant-jelly-like stools containing blood and mucus
D) Sausage-shaped mass in the left lower quadrant
Correct Answer: C) Currant-jelly-like stools containing blood and
mucus
Rationale: Intussusception occurs when one portion of the
intestine telescopes into an adjacent segment, causing
inflammation, swelling, and decreased blood supply. This
results in the sloughing of intestinal mucosa, producing
classic "currant-jelly" stools rich in blood and mucus.
Projectile vomiting is characteristic of hypertrophic pyloric
stenosis, ribbon-like stools point to Hirschsprung disease,
and the palpable sausage-shaped mass in intussusception is
typically located in the right upper or mid-quadrant.
Question 6
A nurse is caring for a patient who underwent a subtotal
