REGIS NU 650 Advanced Pharmacology Study Guide,
Exam Prep Notes, Practice Questions & Comprehensive
Review for Regis University NU650 – Nurse Practitioner
Pharmacology Concepts, Drug Classifications, Clinical
Applications & Prescribing Principles
Question 1: Which component of the health history is considered the most subjective and
provides the foundation for the patient's narrative?
A. Physical examination findings
B. Diagnostic test results
C. Chief complaint and history of present illness
D. Vital signs measurement
**CORRECT ANSWER: C. Chief complaint and history of present illness
Rationale: The chief complaint and history of present illness are subjective data provided by the
patient, forming the narrative foundation for the assessment, whereas physical exams and
vitals are objective.
**Question 2: When assessing a patient from a culture different from your own, what is the
priority action for the nurse practitioner?
A. Assume universal health beliefs apply to all patients
B. Use a family member as the primary interpreter
C. Employ cultural humility and ask open-ended questions about health beliefs
D. Avoid discussing cultural differences to prevent offense
**CORRECT ANSWER: C. Employ cultural humility and ask open-ended questions about health
beliefs
Rationale: Cultural humility involves self-reflection and asking patients about their specific
beliefs, ensuring care is respectful and tailored, unlike assumptions or using untrained
interpreters.
**Question 3: In the OLDCARTS mnemonic for pain assessment, what does the 'R' stand for?
A. Radiation
B. Reason
C. Relief
D. Region
**CORRECT ANSWER: A. Radiation
Rationale: OLDCARTS stands for Onset, Location, Duration, Character, Aggravating factors,
Radiation, Timing, and Severity. Radiation refers to where the pain travels.
**Question 4: Which vital sign change is typically expected in a patient experiencing acute
pain?
A. Decreased blood pressure
B. Decreased respiratory rate
C. Increased heart rate
D. Decreased temperature
**CORRECT ANSWER: C. Increased heart rate
,Rationale: Acute pain stimulates the sympathetic nervous system, often resulting in
tachycardia, increased blood pressure, and increased respiratory rate.
**Question 5: What is the correct technique for measuring blood pressure to ensure
accuracy?
A. The cuff bladder should cover 50% of the upper arm circumference
B. The patient should sit with legs crossed
C. The arm should be supported at heart level
D. The cuff should be placed over clothing
**CORRECT ANSWER: C. The arm should be supported at heart level
Rationale: Supporting the arm at heart level prevents hydrostatic pressure errors. The cuff
should cover 80% of the arm, legs should be uncrossed, and cuffs go on bare skin.
**Question 6: A patient presents with a BMI of 32. How should the nurse practitioner classify
this finding?
A. Underweight
B. Normal weight
C. Overweight
D. Obese
**CORRECT ANSWER: D. Obese
Rationale: A BMI of 30.0 or higher is classified as obese. Overweight is 25.0–29.9, normal is
18.5–24.9, and underweight is below 18.5.
**Question 7: During a skin assessment, a lesion is described as a raised, solid area greater
than 1 cm. What is this lesion?
A. Papule
B. Plaque
C. Nodule
D. Macule
**CORRECT ANSWER: B. Plaque
Rationale: A plaque is a raised, solid lesion greater than 1 cm. A papule is <1 cm, a nodule is
deeper and solid, and a macule is flat.
**Question 8: Which finding suggests a malignant melanoma during a skin examination?
A. Symmetrical shape
B. Uniform color
C. Border irregularity
D. Diameter less than 6 mm
**CORRECT ANSWER: C. Border irregularity
Rationale: The ABCDE rule for melanoma includes Asymmetry, Border irregularity, Color
variation, Diameter >6mm, and Evolving. Symmetry and uniform color are benign features.
**Question 9: What is the primary function of the thyroid gland assessed during a neck
examination?
A. Regulation of blood glucose
B. Regulation of metabolism
,C. Production of insulin
D. Filterings of lymphatic fluid
**CORRECT ANSWER: B. Regulation of metabolism
Rationale: The thyroid gland produces hormones (T3, T4) that regulate metabolic rate. Insulin is
pancreatic, and lymph filtering is done by nodes.
**Question 10: When palpating cervical lymph nodes, which finding is most concerning for
malignancy?
A. Soft and mobile
B. Tender and warm
C. Hard and fixed
D. Small and rubbery
**CORRECT ANSWER: C. Hard and fixed
Rationale: Hard, fixed, non-tender nodes suggest malignancy. Tender, warm nodes suggest
infection. Soft, mobile nodes are typically normal or reactive.
**Question 11: Which cranial nerve is tested by asking the patient to shrug their shoulders
against resistance?
A. Cranial Nerve IX
B. Cranial Nerve X
C. Cranial Nerve XI
D. Cranial Nerve XII
**CORRECT ANSWER: C. Cranial Nerve XI
Rationale: Cranial Nerve XI (Spinal Accessory) innervates the trapezius and sternocleidomastoid
muscles, tested by shoulder shrug and head rotation against resistance.
**Question 12: A patient reports sudden vision loss in one eye. What is the most urgent
differential diagnosis to consider?
A. Presbyopia
B. Retinal detachment
C. Cataracts
D. Conjunctivitis
**CORRECT ANSWER: B. Retinal detachment
Rationale: Sudden vision loss is an emergency often linked to retinal detachment or vascular
occlusion. Cataracts and presbyopia are gradual, and conjunctivitis does not cause vision loss.
**Question 13: During an otoscopic examination, what is a normal finding for the tympanic
membrane?
A. Red and bulging
B. Pearly gray and translucent
C. Perforated with drainage
D. Retracted and amber-colored
**CORRECT ANSWER: B. Pearly gray and translucent
Rationale: A normal tympanic membrane is pearly gray, translucent, and has a visible cone of
light. Redness suggests infection, amber suggests fluid, and perforation is abnormal.
, **Question 14: Which sinus is not accessible for direct palpation during a physical
examination?
A. Frontal
B. Maxillary
C. Sphenoid
D. Ethmoid
**CORRECT ANSWER: C. Sphenoid
Rationale: The sphenoid sinuses are located deep within the skull and cannot be palpated.
Frontal and maxillary sinuses can be palpated for tenderness.
**Question 15: What is the normal finding when inspecting the oral mucosa of a healthy
adult?
A. White patches that wipe off
B. Pink, moist, and smooth
C. Deeply fissured tongue
D. Blue-tinged gums
**CORRECT ANSWER: B. Pink, moist, and smooth
Rationale: Normal oral mucosa is pink, moist, and smooth. White patches may indicate thrush,
fissures may be geographic tongue, and blue gums suggest cyanosis.
**Question 16: When auscultating the lungs, where are bronchial breath sounds normally
heard?
A. Over the peripheral lung fields
B. Over the trachea and larynx
C. Over the lower lobes
D. Over the cardiac apex
**CORRECT ANSWER: B. Over the trachea and larynx
Rationale: Bronchial sounds are loud and high-pitched, normally heard over the trachea.
Bronchovesicular sounds are heard between scapulae, and vesicular over peripheral fields.
**Question 17: A patient presents with wheezing. What pathophysiology does this sound
indicate?
A. Fluid in the alveoli
B. Narrowed airways
C. Pleural friction
D. Consolidation of lung tissue
**CORRECT ANSWER: B. Narrowed airways
Rationale: Wheezing is a continuous musical sound caused by air moving through narrowed
airways, common in asthma or COPD. Crackles indicate fluid, friction rub indicates pleuritis.
**Question 18: Which landmark is used to identify the location of the apex of the heart?
A. Second intercostal space, right sternal border
B. Fourth intercostal space, left sternal border
C. Fifth intercostal space, midclavicular line
D. Second intercostal space, left sternal border
**CORRECT ANSWER: C. Fifth intercostal space, midclavicular line
