NUR 603 Exam 2: Advanced Nursing Practicum -
St. Thomas University Updated and Latest
Questions and Correct Answers with Rationale
1. When assessing a patient with suspected acute cholecystitis, which physical examination
maneuver is most appropriate to confirm the diagnosis?
A. McBurney’s point tenderness
B. Psoas sign
C. Rovsing’s sign
D. Murphy’s sign
Correct Answer: D
Rationale: Murphy’s sign is highly specific for detecting gallbladder inflammation by
palpating the right upper quadrant during inspiration. The clinician asks the patient to take
a deep breath while applying pressure below the costal margin. A positive test occurs when
the patient experiences sharp pain and abruptly stops inhaling. This maneuver helps
differentiate biliary colic from other causes of abdominal pain in a clinical setting.
Advanced practice nurses must master this technique to facilitate prompt diagnostic
imaging and surgical referral.
2. A 55-year-old male with a history of heart failure presents with increased dyspnea and
peripheral edema. Which laboratory value is most indicative of worsening heart failure?
A. Serum Creatinine
B. Brain Natriuretic Peptide (BNP)
C. Alanine Aminotransferase (ALT)
D. Glycated Hemoglobin (HbA1c)
Correct Answer: B
Rationale: Brain Natriuretic Peptide is released by the ventricles in response to increased
wall tension and volume overload. It serves as a reliable biomarker for diagnosing and
managing acute decompensated heart failure. Elevated levels correlate with the severity of
the patient’s symptoms and overall clinical prognosis. Interpreting BNP alongside physical
findings allows the nurse practitioner to adjust diuretic therapy effectively. This objective
measure is essential for monitoring the efficacy of pharmacological interventions in heart
failure patients.
3. In the management of Type 2 Diabetes Mellitus, what is the primary reason for initiating
Metformin as the first-line pharmacological therapy?
A. It increases insulin secretion from pancreatic beta cells
,B. It causes significant weight gain to improve metabolic rate
C. It decreases hepatic glucose production and improves insulin sensitivity
D. It is primarily used to treat associated hyperlipidemia
Correct Answer: C
Rationale: Metformin functions primarily by inhibiting gluconeogenesis in the liver and
enhancing glucose uptake in peripheral tissues. It is widely recommended as the initial
treatment due to its proven efficacy in lowering HbA1c levels. Unlike sulfonylureas, it has a
low risk of causing hypoglycemia when used as monotherapy. Additionally, Metformin is
associated with weight neutrality or modest weight loss, which benefits most diabetic
patients. Advanced practitioners must evaluate renal function before prescribing this
medication to prevent lactic acidosis.
4. An advanced practice nurse is coordinating care for a complex patient with multiple
comorbidities. Which action best demonstrates collaborative practice within an
interdisciplinary team?
A. Engaging in regular huddles with pharmacists, social workers, and physicians
B. Limiting communication to written notes in the electronic health record
C. Making all treatment decisions independently to ensure efficiency
D. Focusing exclusively on the nursing aspect of care without external input
Correct Answer: A
Rationale: Collaborative practice involves active communication and shared decision-
making among various healthcare professionals to improve patient outcomes. Regular
huddles allow the team to align clinical goals and address potential barriers to care. This
approach ensures that the expertise of each discipline is utilized for the patient’s benefit.
Effective teamwork reduces medical errors and enhances the overall safety of the
healthcare delivery system. It is a core competency for advanced nursing practitioners
working in modern clinical environments.
5. During a cardiovascular assessment, the nurse practitioner auscultates a low-pitched sound
in early diastole at the apex. This finding is most likely:
A. An S4 gallop
B. A friction rub
C. An S3 gallop
D. A mid-systolic click
Correct Answer: C
, Rationale: An S3 gallop occurs during the rapid filling phase of the ventricles immediately
after the second heart sound. It is often associated with conditions of volume overload,
such as congestive heart failure. In older adults, this finding usually signifies decreased
ventricular compliance or dilated cardiomyopathy. The sound is best heard with the bell of
the stethoscope placed at the cardiac apex. Identifying an S3 is a critical component of the
advanced physical exam for cardiovascular monitoring.
6. A 68-year-old patient with chronic obstructive pulmonary disease (COPD) presents with an
acute exacerbation. Which class of medication is essential for rapid symptom relief?
A. Inhaled Corticosteroids
B. Long-Acting Beta-Agonists (LABA)
C. Leukotriene Receptor Antagonists
D. Short-Acting Beta-Agonists (SABA)
Correct Answer: D
Rationale: Short-acting beta-agonists like Albuterol are the mainstay for the immediate
relief of bronchospasm during COPD exacerbations. These medications work by stimulating
beta-2 receptors in the lungs to promote smooth muscle relaxation. Rapid bronchodilation
helps to reduce the work of breathing and improves gas exchange during acute distress.
Advanced practice nurses should assess the patient’s technique and frequency of use to
determine the severity of the disease. Stabilization of the airway is the first priority in
managing respiratory emergencies.
7. When evaluating a patient with a suspected cranial nerve VII palsy (Bell’s Palsy), which
clinical finding would be most characteristic?
A. Asymmetry of the face when smiling
B. Loss of sensation on the forehead
C. Inability to shrug the shoulders
D. Deviation of the tongue to one side
Correct Answer: A
Rationale: Cranial nerve VII, the facial nerve, controls the muscles of facial expression and
some sensory functions. Bell’s Palsy typically presents as unilateral facial drooping,
including the inability to close the eye or wrinkle the forehead. This condition results from
inflammation or compression of the nerve as it exits the skull. Clinicians must distinguish
this peripheral nerve lesion from a central stroke, where forehead movement is often
preserved. Early treatment with corticosteroids is often indicated to improve the chances
of a full recovery.
