Introduction
This comprehensive Diagnostic Readiness Test (DRT) is designed to rigorously assess the diagnostic reasoning,
clinical judgment, and decision-making skills essential for advanced nursing practice. The examination focuses on
the candidate's ability to perform comprehensive health assessments, formulate accurate differential diagnoses,
select and interpret appropriate diagnostic tests, and apply evidence-based guidelines to real-world clinical
scenarios. Candidates will be challenged with multiple-choice and case-based questions that emphasize critical
thinking, patient safety, and the integration of pathophysiological principles. This assessment serves as a critical
,tool for evaluating readiness to make accurate and timely diagnoses across diverse patient populations and
healthcare settings.
SECTION ONE: QUESTIONS 1–100
1. A 55-year-old female presents with fatigue, weight gain, constipation, and cold intolerance. On
examination, you note bradycardia and dry, coarse skin. Which of the following laboratory findings would
most likely confirm your suspected diagnosis?
A. Elevated free T4 and decreased TSH
B. Decreased free T4 and elevated TSH
C. Elevated free T4 and elevated TSH
D. Decreased free T4 and decreased TSH
🟢B
🔴 RATIONALE: The patient's presentation is classic for hypothyroidism. In primary hypothyroidism, the thyroid
gland fails to produce sufficient thyroid hormone, leading to decreased free T4. This triggers the pituitary to
increase TSH production, resulting in elevated TSH. Therefore, decreased free T4 and elevated TSH are the
hallmark laboratory findings.
,2. A 68-year-old male with a history of hypertension and type 2 diabetes mellitus is being evaluated for a
new onset of shortness of breath and bilateral lower extremity edema. His blood pressure is 158/94 mmHg,
and heart rate is 88 bpm. An ECG shows left ventricular hypertrophy. Which of the following is the most
appropriate initial diagnostic test to assess his cardiac function?
A. Chest X-ray
B. Transthoracic echocardiogram
C. Cardiac catheterization
D. Exercise stress test
🟢B
🔴 RATIONALE: The patient has signs and symptoms suggestive of heart failure. A transthoracic
echocardiogram is the most appropriate initial diagnostic test to assess cardiac structure and function, including
left ventricular ejection fraction. A chest X-ray may show cardiomegaly or pulmonary congestion but does not
provide detailed functional information. Cardiac catheterization is invasive and not the initial step. An exercise
stress test is contraindicated in acute decompensated heart failure.
3. A 45-year-old male presents with a two-week history of a cough, low-grade fever, and night sweats. He
reports a 10-pound unintentional weight loss over the past month. He has a history of HIV, with a CD4 count
of 180 cells/mm³. A chest X-ray reveals a cavitary lesion in the right upper lobe. Which of the following is the
most appropriate initial diagnostic test?
A. Sputum culture and sensitivity
B. Interferon-gamma release assay (IGRA)
, C. Acid-fast bacilli (AFB) smear and culture
D. Tuberculin skin test (TST)
🟢C
🔴 RATIONALE: Given the patient's symptoms, risk factors (HIV), and chest X-ray findings, tuberculosis (TB) is
the primary concern. The initial diagnostic test for active TB is an AFB smear and culture of sputum. While IGRA
and TST can indicate infection, they cannot distinguish between latent and active disease. A sputum culture and
sensitivity, while important, is not the first step; an AFB smear provides a rapid preliminary result.
4. A 65-year-old male with a 40-pack-year smoking history presents with a chronic cough, hemoptysis, and
weight loss. A chest X-ray reveals a mass in the right upper lobe. Which of the following is the most
important initial diagnostic step?
A. Positron emission tomography (PET) scan
B. Bronchoscopy with biopsy
C. Sputum cytology
D. Computed tomography (CT) scan of the chest
🟢B
🔴 RATIONALE: The patient has a high suspicion for lung cancer. The gold standard for diagnosis is a tissue
biopsy. Bronchoscopy with biopsy allows for direct visualization and tissue sampling. A CT scan and PET scan
are important for staging, but neither provides a definitive diagnosis. Sputum cytology has a low sensitivity.
