NUR 621 EXAM 280 ACTUAL QUESTIONS AND CORRECT
ANSWERS WITH RATIONALE LATEST 2026 ALREADY
GRADED A+
This comprehensive set of 280 unique, high-level NUR 621 exam questions
covers essential graduate-level primary care and advanced nursing topics.
Each question presents a distinct clinical scenario addressing cardiology,
pulmonology, endocrinology, gastroenterology, nephrology, neurology,
rheumatology, hematology, dermatology, mental health, and pharmacology.
Questions cover pathophysiology, diagnostic reasoning,
pharmacotherapeutics, evidence-based practice, patient education, and
priority nursing interventions. Every question includes four multiple-choice
options, a correct answer, and a detailed rationale explaining the clinical
reasoning, mechanisms of action, and evidence-based guidelines. No questions
are repeated across the collection. This resource strengthens clinical
judgment, reinforces advanced practice nursing competencies, and prepares
students for comprehensive graduate-level nursing examinations.
1. You are seeing a 72-year-old woman with pneumonia. She is generally active
and still plays golf despite a history of HTN and HF. What is the priority for this
patient?
A) Order a stat echocardiogram
B) Perform a fall risk assessment
C) Start broad-spectrum antibiotics
D) Check her hemoglobin A1c
Answer: B
Rationale: In older adults, especially those with multiple comorbidities,
hospitalization and acute illness significantly increase the risk of falls. A fall risk
assessment is the priority to ensure patient safety and prevent injury.
2. Your collaborating physician has asked you to present a credible source of
evidence at the next staff meeting. Which statement is true of clinical practice
guidelines?
A) They are opinion-based recommendations from expert panels
B) They are only useful for inpatient care settings
,C) They are evidence-based when conducted systematically and recommendations
are formed using the evidence
D) They are legally binding protocols that must be followed
Answer: C
Rationale: High-quality clinical practice guidelines are developed through a
systematic review of evidence. The recommendations are then graded based on the
strength of that evidence, making them a credible source for guiding practice.
3. Which represents a primary source of evidence?
A) A meta-analysis
B) A clinical practice guideline
C) An individual study
D) A systematic review
Answer: C
Rationale: Primary sources are original research studies or reports. They are the
foundational evidence upon which secondary sources like systematic reviews and
meta-analyses are built.
4. What source of evidence best supports practice change?
A) A single case study
B) Expert opinion from a senior clinician
C) A peer-reviewed systematic review
D) A non-experimental descriptive study
Answer: C
Rationale: Peer-reviewed systematic reviews and meta-analyses are considered the
highest level of evidence. They synthesize findings from multiple primary studies
to provide a comprehensive and robust answer to a clinical question, making them
the strongest foundation for practice change.
5. The AGACNP is working in a busy Emergency Department and is caring for a
patient with a deep wound. The NP learns that the patient's last Tetanus vaccine
was 7 years ago. What would be the appropriate next step?
A) No action is needed; the vaccine is still current
B) Order a tetanus vaccine since it has been over 5 years since the last booster
C) Order a tetanus titer to check immunity
D) Clean the wound and discharge the patient
Answer: B
Rationale: For a patient with a deep or contaminated wound, a tetanus booster is
recommended if it has been more than 5 years since their last dose. This patient is
outside that window and requires a booster.
,6. A patient with Crohn's Disease who had her terminal ileum surgically removed
last year is complaining of fatigue over the past 2 months. What do you suspect?
A) Iron deficiency anemia
B) Vitamin B12 deficiency
C) Folate deficiency
D) Vitamin D deficiency
Answer: B
Rationale: The terminal ileum is the primary site of Vitamin B12 absorption.
Surgical removal of this section leads to malabsorption of B12, which can manifest
as fatigue, among other symptoms.
7. A 48-year-old woman comes to the clinic because of gnawing epigastric pain for
the past 3 months. She says the pain occurs 2-3 hours after eating and is relieved
by antacids. Which of the following is most likely related to her underlying
problem?
A) Zollinger-Ellison syndrome
B) H. Pylori Infection
C) Gallstones
D) Chronic pancreatitis
Answer: B
Rationale: This presentation—gnawing epigastric pain occurring 2-3 hours
postprandially (a "hunger" or "night" pain) and relieved by food or antacids—is
classic for a duodenal ulcer. The most common cause of peptic ulcer disease is *H.
pylori* infection.
8. What anatomic abnormality is responsible for acid reflux?
A) A hiatal hernia
B) Lower esophageal sphincter pressure lower than 10 mm Hg
C) Increased gastric acid production
D) Delayed gastric emptying
Answer: B
Rationale: The lower esophageal sphincter (LES) acts as a barrier to prevent
gastric contents from refluxing into the esophagus. When the resting pressure of
the LES is abnormally low (typically <10 mm Hg), it fails to close properly,
allowing acid to reflux and cause GERD symptoms.
9. A 65-year-old patient presents to the clinic with a complaint of a painful rash.
On exam, you note round lesions in various phases on the left forehead, extending
, down to the tip of her nose. She also complains of profuse tearing and pain in her
left eye. What is the most likely diagnosis?
A) Impetigo
B) Contact dermatitis
C) Varicella zoster virus (Shingles)
D) Herpes simplex virus
Answer: C
Rationale: The presentation of a painful, vesicular rash in a dermatomal
distribution on the forehead, especially with involvement of the tip of the nose
(Hutchinson's sign) and eye symptoms, is classic for herpes zoster ophthalmicus,
caused by the varicella-zoster virus.
10. A patient presents to the urgent care with a rash consisting of welts and intense
itching. The APN diagnoses the patient with urticaria. What is a potentially life-
threatening condition that can occur in a patient with urticaria?
A) Anaphylaxis
B) Angioedema
C) Stevens-Johnson Syndrome
D) Toxic Epidermal Necrolysis
Answer: B
Rationale: Angioedema is a deeper swelling of the dermis and subcutaneous tissues
that often accompanies urticaria. When it affects the airway (larynx, tongue, or
pharynx), it can be life-threatening due to airway compromise.
11. A 25-year-old female presents with four days of increasing dysphagia, dysuria,
and a macular rash on her trunk. Her temperature is 103.1°F. On exam, an
erythematous rash covers about 10% of her body surface area, with some areas
forming blisters and bullae. The only medication she is taking is Erythromycin for
acne. What is the most likely diagnosis?
A) Urticaria
B) Scabies
C) Stevens-Johnson Syndrome
D) Cellulitis
Answer: C
Rationale: This presentation of a prodromal illness (fever, malaise) followed by a
rapidly progressive, widespread, erythematous rash with blistering and bullae,
especially in the context of a new medication like erythromycin, is highly
suspicious for Stevens-Johnson syndrome (SJS).
