PRACTICE CARE OF ADULTS ACROSS THE LIFESPAN –
WALDEN UNIVERSITY | EXPERT VERIFIED | 150 VERIFIED
Q&A | DETAILED RATIONALES | NGN-ALIGNED | PASS
GUARANTEED – A+ GRADED
Question 1
A nurse practitioner is evaluating a 45-year-old female who presents with fatigue, weight gain, and
cold intolerance. Physical examination reveals dry skin, bradycardia, and delayed deep tendon
reflexes. Which of the following is the most appropriate initial laboratory test?
A. Free T4
B. Thyroid-stimulating hormone (TSH)
C. T3
D. Thyroid peroxidase antibodies
Correct Answer: B
Rationale: TSH is the most appropriate initial screening test for suspected hypothyroidism. The
client's symptoms (fatigue, weight gain, cold intolerance, dry skin, bradycardia, delayed reflexes) are
classic for hypothyroidism. If TSH is elevated, free T4 should be checked to confirm the diagnosis.
Question 2
A nurse practitioner is evaluating a 55-year-old male who presents with chest pain that radiates to
the left arm and jaw. The pain began 45 minutes ago and is not relieved by rest. Which of the
following is the priority diagnostic test?
A. Chest X-ray
B. 12-lead ECG
C. Cardiac troponin
D. Echocardiogram
Correct Answer: B
Rationale: A 12-lead ECG should be obtained within 10 minutes for a client with suspected acute
coronary syndrome to evaluate for ST-segment elevation. Cardiac troponin is important but may not
be elevated early. Chest X-ray and echocardiogram are not the priority.
Question 3
A nurse practitioner is evaluating a 30-year-old female who presents with dysuria, urinary frequency,
and urgency. She denies fever, chills, or flank pain. Which of the following is the most appropriate
initial diagnostic test?
,2
A. Urine culture
B. Urinalysis
C. Renal ultrasound
D. CT scan of the abdomen
Correct Answer: B
Rationale: Urinalysis is the most appropriate initial diagnostic test for suspected uncomplicated
urinary tract infection. It can detect leukocyte esterase, nitrites, white blood cells, and bacteria.
Urine culture may be ordered if the urinalysis is abnormal.
Question 4
A nurse practitioner is evaluating a 60-year-old male who presents with progressive dyspnea on
exertion and fatigue. Physical examination reveals a systolic ejection murmur at the right upper
sternal border. Which of the following is the most appropriate diagnostic test?
A. Chest X-ray
B. Echocardiogram
C. Cardiac stress test
D. Cardiac catheterization
Correct Answer: B
Rationale: Echocardiogram is the most appropriate diagnostic test for suspected aortic stenosis
(systolic ejection murmur at the right upper sternal border). It can evaluate valve structure, function,
and severity.
Question 5
A nurse practitioner is evaluating a 25-year-old female who presents with a sore throat, fever, and
fatigue. Physical examination reveals enlarged tonsils with white exudates and tender anterior
cervical lymphadenopathy. Which of the following is the most appropriate diagnostic test?
A. Complete blood count
B. Rapid strep test or throat culture
C. Monospot test
D. Chest X-ray
Correct Answer: B
Rationale: A rapid strep test or throat culture is the most appropriate diagnostic test for suspected
streptococcal pharyngitis. The client's symptoms and findings (tonsillar exudates, tender anterior
cervical lymphadenopathy) are classic for strep throat.
Question 6
,3
A nurse practitioner is evaluating a 50-year-old female who presents with right upper quadrant
abdominal pain that occurs after eating fatty meals. Which of the following is the most appropriate
initial diagnostic test?
A. Abdominal ultrasound
B. CT scan of the abdomen
C. HIDA scan
D. Endoscopic retrograde cholangiopancreatography (ERCP)
Correct Answer: A
Rationale: Abdominal ultrasound is the most appropriate initial diagnostic test for suspected
gallbladder disease (cholelithiasis). It can detect gallstones and gallbladder wall thickening.
Question 7
A nurse practitioner is evaluating a 65-year-old male who presents with a sudden onset of weakness
on the right side of his body and difficulty speaking. Symptoms began 20 minutes ago. Which of the
following is the priority diagnostic test?
A. Complete blood count
B. CT scan of the head (non-contrast)
C. MRI of the brain
D. Carotid ultrasound
Correct Answer: B
Rationale: A non-contrast CT scan of the head should be obtained immediately for a client with
suspected stroke to rule out hemorrhagic stroke before administering thrombolytic therapy.
Question 8
A nurse practitioner is evaluating a 40-year-old female who presents with fatigue, joint pain, and a
malar rash on her face. Which of the following is the most specific diagnostic test?
A. Rheumatoid factor
B. Anti-double-stranded DNA (anti-dsDNA)
C. Erythrocyte sedimentation rate (ESR)
D. C-reactive protein (CRP)
Correct Answer: B
Rationale: Anti-double-stranded DNA (anti-dsDNA) is highly specific for systemic lupus
erythematosus (SLE). The client's symptoms (fatigue, joint pain, malar rash) are consistent with SLE.
Question 9
A nurse practitioner is evaluating a 55-year-old male who presents with a persistent cough,
hemoptysis, and weight loss. He has a 30-pack-year smoking history. Which of the following is the
most appropriate initial diagnostic test?
, 4
A. Sputum cytology
B. Chest X-ray
C. CT scan of the chest
D. Bronchoscopy
Correct Answer: B
Rationale: Chest X-ray is the most appropriate initial diagnostic test for suspected lung cancer. It can
detect masses, nodules, and other abnormalities.
Question 10
A nurse practitioner is evaluating a 35-year-old female who presents with a painful, swollen left knee
that began suddenly. She has a fever and chills. Which of the following is the most appropriate
diagnostic test?
A. X-ray of the knee
B. Arthrocentesis with synovial fluid analysis
C. MRI of the knee
D. Serum uric acid
Correct Answer: B
Rationale: Arthrocentesis with synovial fluid analysis is the most appropriate diagnostic test for
suspected septic arthritis. The client's symptoms (sudden onset of painful, swollen joint with fever
and chills) are concerning for septic arthritis.
Question 11
A nurse practitioner is prescribing metformin for a client with newly diagnosed type 2 diabetes.
Which of the following is the primary mechanism of action of metformin?
A. Increases insulin secretion from pancreatic beta cells
B. Decreases hepatic glucose production and increases insulin sensitivity
C. Increases glucose reabsorption in the kidneys
D. Delays carbohydrate absorption in the intestines
Correct Answer: B
Rationale: Metformin primarily decreases hepatic gluconeogenesis and increases peripheral insulin
sensitivity. It does not increase insulin secretion (sulfonylureas), increase glucose reabsorption
(SGLT2 inhibitors), or delay carbohydrate absorption (alpha-glucosidase inhibitors).
Question 12
A nurse practitioner is prescribing lisinopril for a client with hypertension. Which of the following is a
common side effect?
A. Hypokalemia
B. Dry cough
