Appeared in: INI-CET EXAM -2026

Explanation

• The correct option combines the most appropriate diagnostic test for each listed condition.
• A CT scan is the primary imaging modality for visualizing pancreatic pseudocysts, as confirmed by its ability to detail pancreatic fluid collections.
• FNAC is the standard procedure for cytological evaluation of thyroid nodules to rule out malignancy.
• A PET scan is a crucial tool in modern oncology for staging cancers like prostate cancer and detecting metastasis.
• MRCP is the investigation of choice for non-invasively visualizing the biliary tree in cases of obstructive jaundice to find the site and cause of blockage.

Why Other Options Were Wrong

• Option B: This option incorrectly matches Pancreatic pseudocyst with a PET scan (A-3) and Prostate cancer with a CT scan (C-4). While a CT scan can be used for prostate cancer, a PET scan is more specific for staging metastatic disease. A PET scan is not the primary tool for a pseudocyst.
• Option C: This option incorrectly pairs Pancreatic pseudocyst with MRCP (A-2), Prostate cancer with a CT scan (C-4), and Obstructive jaundice with a PET scan (D-3). MRCP is for ducts, not primarily for pseudocysts. A PET scan is not the first-line investigation for jaundice.
• Option D: This option incorrectly matches Thyroid nodule with MRCP (B-2) and Obstructive jaundice with FNAC (D-1). MRCP has no role in evaluating thyroid nodules. FNAC is not used to diagnose the cause of obstructive jaundice; it's for cytology of masses.

Clinical Relevance

• Nursing practice connection: Use the key finding related to Matching clinical conditions with their most appropriate diagnostic investigations to guide bedside assessment, documentation, and the next nursing action.
• Selecting the correct diagnostic test is crucial for accurate diagnosis, preventing delays in treatment, and avoiding unnecessary costs and patient exposure to radiation or invasive procedures.
• A nurse's role includes preparing the patient for these procedures, explaining what to expect, and monitoring for any post-procedure complications.
• Understanding the rationale behind test selection helps nurses anticipate patient needs and educate them effectively about their care plan.

How to Approach the Question

• This is a 'match the following' question. The goal is to create correct pairs from two columns.
• First, analyze each clinical condition in the first column.
• For each condition, review the investigation options in the second column and determine the most logical and standard diagnostic tool.
• Match 'Pancreatic pseudocyst'. A CT scan is excellent for visualizing abdominal structures and fluid collections. This points to A-4.
• Match 'Thyroid nodule'. FNAC is the definitive test to check for cancer cells. This points to B-1.
• Match 'Prostate cancer'. A PET scan is used for staging and finding metastases. This points to C-3.
