Screening for cervical cancer is done at PHC by?

Appeared in: RUHS, Jaipur, M.Sc Nursing Entrance Exam-2021

Explanation

The Pap smear is a standard cytological screening test designed to detect precancerous and cancerous cells from the cervix.
It is a cost-effective and relatively simple procedure that can be implemented in large-scale public health programs, making it suitable for the Primary Health Centre (PHC) level.
The primary goal of Pap smear screening is to identify cervical dysplasia (abnormal cell growth) early, allowing for treatment before it progresses to invasive cancer, thereby significantly reducing mortality rates.

Option A: While a history and clinical examination are fundamental parts of any patient assessment, they are not sensitive enough to detect the microscopic, asymptomatic, precancerous lesions that Pap smears are designed to find.
Option C: Colposcopy is a diagnostic procedure, not a primary screening tool. It involves using a magnifying instrument to examine the cervix, usually after an abnormal Pap smear result.
Option D: MRI is an advanced imaging modality used for staging, not screening. It helps determine the size of a confirmed tumor and whether it has spread to lymph nodes or other organs.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Cervical Cancer Screening at Primary Healthcare Level as background academic context rather than a clinical decision trigger.
Nurses play a critical role in health education, encouraging women to participate in regular cervical screening programs and explaining the procedure to alleviate anxiety.
Accurate patient instruction before a Pap smear is a key nursing responsibility, as failure to follow guidelines (e.g., douching before the test) can lead to an inaccurate or unreadable sample.
Understanding the difference between screening, diagnosis, and staging is essential for nurses to provide correct information and manage patient expectations and referrals appropriately.

How to Approach the Question

First, identify the key terms in the question: 'Screening', 'cervical cancer', and 'PHC' (Primary Health Centre).
Understand that 'screening' refers to a test performed on a large, asymptomatic population to detect early signs of a disease.
Recognize that 'PHC' implies a setting where tests need to be relatively simple, cost-effective, and widely applicable.
Evaluate each option against these criteria.
A 'Pap smear' is a well-known, cell-based screening test.
'Colposcopy' and 'MRI' are more complex, expensive procedures used for diagnosis and staging, respectively, not initial screening.
