A nurse assisting in the care of a client, places the tocodynamometer (TOCO) transducer on a client's fundus and secures it in place. The client asks the nurse to explain the purpose of the monitoring device. Which of the following responses should the nurse make?

"This monitor gives me information related to fetal heart rate fluctuations during your labor."

"This monitor measures the intensity and frequency of your contractions so I can observe labor progress."

"This monitor allows me to observe your labor progress. By observing the pattern, I can tell how strong your contractions are."

"This monitor provides me with information related to the duration and frequency of your contractions."

Answer and Explanation

The Correct Answer is D

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 C

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.

A. By calculating the time between the beginning of one contraction to the beginning of the next B. By measuring the duration of the contractions C. By assessing the intensity of the contractions D. By palpating the resting tone of the uterus

Correct Answer is A

Explanation

A. By calculating the time between the beginning of one contraction to the beginning of the next – Correct; frequency is measured from the start of one contraction to the start of the next.

B. By measuring the duration of the contractions – Incorrect; duration refers to how long a contraction lasts, not frequency.
