Identify the following sample collection tube shown:

Appeared in: AIIMS Delhi NO- 2019

Explanation

The image displays an Ayre's spatula, a wooden or plastic instrument used in gynecology.
This spatula has a specially shaped end designed to conform to the cervix for cell collection.
Its primary and specific use is to collect cervical cells for a Papanicolaou (Pap) test, commonly known as a Pap smear, to screen for cervical cancer.

Option B: A throat swab uses a different instrument, typically a long stick with a cotton or synthetic tip, to collect samples from the back of the throat.
Option C: While the collected sample could potentially be used for a culture, 'Culture' is a general laboratory process, not the name of the collection procedure or the instrument. The instrument is specific to a Pap smear.
Option D: This option is incorrect because the instrument is clearly identifiable as an Ayre's spatula, and its use is directly related to one of the other options (Pap's smear).

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identification and use of gynecological instruments as background academic context rather than a clinical decision trigger.
Nurses play a crucial role in patient education for Pap smears, instructing patients to avoid douching, sexual intercourse, and vaginal medications for 48 hours before the test to ensure an accurate sample.
During the procedure, the nurse assists by preparing the equipment, positioning the patient correctly (lithotomy position), and providing emotional support.
What if? If a patient presents for a Pap smear but has heavy menstrual bleeding, the procedure is typically postponed. The presence of blood can obscure the cervical cells on the slide, potentially leading to an inaccurate or unreadable result.

How to Approach the Question

First, carefully examine the image to identify the instrument. Note its material (wood), shape (flat, with a specially contoured end), and size.
Recognize the instrument as an Ayre's spatula, a tool used in gynecological examinations.
Recall the primary function of an Ayre's spatula, which is to scrape cells from the cervix.
Evaluate the given options. 'Pap's smear' is the specific procedure where this instrument is used.
Eliminate the other options. 'Throat swab' uses a different tool. 'Culture' is a general lab test, not a specific procedure tied to this instrument.
Conclude that the instrument is used for a Pap's smear, making it the correct answer.
