Question 203 · LEK · Assessment of fetal condition and development
Indicate the true statements concerning the cardiotocography (CTG) analysis:
1) short-term variability (STV) is particularly helpful in predicting the risk of metabolic acidosis in the fetus;
2) normal fetal heart rate (FHR) is 100 to 160 beats per minute;
3) lack of an acceleration in the record up to 180 minutes is regarded as normal and as a sign of deep sleep of the fetus;
4) correct long-term variability (LTV) is between 5 and 25 beats per minute;
5) sinusoidal rhythm indicates a high degree of fetal distress.
The correct answer is:
2) normal fetal heart rate (FHR) is 100 to 160 beats per minute;
3) lack of an acceleration in the record up to 180 minutes is regarded as normal and as a sign of deep sleep of the fetus;
4) correct long-term variability (LTV) is between 5 and 25 beats per minute;
5) sinusoidal rhythm indicates a high degree of fetal distress.
The correct answer is:
- A. 1,3,5.
- B. 1,5.
- C. 2,3.
- D. 1,4,5.
- E. 2,3,4.
Hint
Check each number against standard norms: the normal baseline range and the usual maximum length of fetal quiet sleep.
