Correct Answer is D
Explanation
A. "This monitor gives me information related to fetal heart rate fluctuations during your labor." – Incorrect; the TOCO does not monitor fetal heart rate; the fetal heart rate is detected using a Doppler or fetal scalp electrode.
B. "This monitor measures the intensity and frequency of your contractions so I can observe labor progress." – Incorrect; the TOCO can measure frequency and duration, but not intensity (which requires an intrauterine pressure catheter).
C. "This monitor allows me to observe your labor progress. By observing the pattern, I can tell how strong your contractions are." – Incorrect; TOCO does not measure contraction strength, only duration and frequency.
D. "This monitor provides me with information related to the duration and frequency of your contractions." – Correct; a TOCO detects and records contraction frequency and duration, but not intensity.
Correct Answer is A
Explanation
A. Lightening – Correct; "lightening" occurs when the fetal head descends into the pelvis, reducing pressure on the diaphragm, making it easier to breathe.
B. Decreasing chest diameter – Incorrect; the chest diameter does not decrease; instead, the diaphragm moves upward due to uterine growth.
C. Decreased carbon dioxide production – Incorrect; CO₂ production remains stable during pregnancy.
D. Hyperventilation – Incorrect; while pregnancy increases respiratory effort, the client is experiencing relief, not hyperventilation.
