Appeared in: RUHS, Jaipur, PB B.Sc Nursing Entrance-2022
Explanation
- A fetoscope, commonly a Pinard horn, is an acoustic (non-electronic) instrument specifically designed for obstetric use.
- Its primary and intended function is to auscultate, or listen to, the heart sounds of the fetus through the mother's abdomen.
- This allows for intermittent monitoring of the fetal heart rate (FHR), which is a crucial indicator of fetal well-being during pregnancy and labor.
- The instrument works by amplifying sound through its horn shape, making the faint fetal heartbeat audible to the human ear.
Why Other Options Were Wrong
- Option A: A standard medical stethoscope, not a fetoscope, is used to auscultate the mother's heart sounds. A key nursing skill is to differentiate the mother's pulse from the fetal heart rate during assessment.
- Option B: Visualization of the fetus is done using imaging technology, primarily ultrasonography (ultrasound). While a specialized surgical procedure called 'endoscopic fetoscopy' uses a fiber-optic scope to see the fetus, the common instrument known as a fetoscope (Pinard horn) is purely for listening.
- Option D: Maternal abdominal sounds, such as bowel sounds (borborygmi), are assessed with a standard stethoscope as part of a general abdominal examination.

Clinical Relevance
- Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain The primary function of a fetoscope in obstetric care as background academic context rather than a clinical decision trigger.
- Monitoring the Fetal Heart Rate (FHR) is a fundamental nursing assessment in maternity care. The normal FHR is between 110 and 160 beats per minute.
- When using a fetoscope, the nurse must simultaneously palpate the mother's radial pulse to differentiate the maternal heart rate from the fetal heart rate, ensuring an accurate count.
- A significant change in FHR (tachycardia or bradycardia) can be an early sign of fetal distress, requiring prompt reporting and potential intervention.
How to Approach the Question
- This is a factual recall question testing knowledge of common obstetric instruments.
- First, identify the keyword in the stem: 'Foetoscope'.
- Recall the primary purpose of this instrument. The 'scope' part suggests observation, and 'foeto' relates to the fetus. In this context, 'observation' is through hearing (auscultation).
- Evaluate the options based on this knowledge. A fetoscope is specifically for the fetus, which eliminates options related to the mother's heart or abdomen.
- Differentiate between 'hearing' and 'visualizing'. A fetoscope is an acoustic horn, designed for listening, not a camera for seeing.
- Select the option that accurately describes listening to the fetal heart sounds.
