A nurse is caring for a client who is on the electronic fetal monitor and the nurse notices that the client is experiencing tachysystole.
Which of the following describes tachysystole?
A reaction from an epidural.
When the fetus's heart rate drops below baseline.
More than five contractions in 10 minutes.
Initiating the use of Pitocin.
The Correct Answer is C
Choice A rationale
A reaction from an epidural can cause side effects such as hypotension and shivering, but it is not related to tachysystole.
Choice B rationale
When the fetus's heart rate drops below baseline, it is termed bradycardia, not tachysystole. This condition can occur due to various reasons, including cord prolapse or placental insufficiency.
Choice C rationale
Tachysystole is defined as more than five contractions in 10 minutes. This condition can lead to reduced blood flow to the fetus, resulting in fetal distress.
Choice D rationale
Pitocin is a medication used to induce labor and can cause tachysystole, but the administration of Pitocin itself is not the definition of tachysystole. It's the increased frequency of contractions that defines the condition.

Correct Answer is C
Explanation
Choice A rationale
G4T1 P1 A1 L2 implies the client has been pregnant 4 times, with 1 term birth, 1 preterm birth, 1 abortion, and 2 living children. This does not include the correct number of
pregnancies or abortions for this client.
Choice B rationale
G5T2 P0 A2 L2 indicates 5 pregnancies, 2 term births, no preterm births, 2 abortions, and 2 living children. This does not correctly account for the preterm birth and abortion history
provided.
Choice C rationale
G5T1 P1 A2 L2 is the correct answer, as it denotes 5 pregnancies (including the current one), 1 term birth, 1 preterm birth, 2 abortions, and 2 living children, aligning with the client's
history.
Choice D rationale
G5T1 P1 A1 L3 indicates 5 pregnancies, 1 term birth, 1 preterm birth, 1 abortion, and 3 living children. The client has only 2 living children, so this is incorrect.
Correct Answer is B
Explanation
Choice A rationale
The fetal heartbeat cannot typically be heard via Doppler as early as 4 weeks of pregnancy. At this stage, the heart is still developing, and it is too soon for external detection with a Doppler device.
Choice B rationale
The fetal heartbeat is generally detectable by an external Doppler device around 10-12 weeks of pregnancy. This is the period when the heartbeat is strong enough to be picked up by the device.
Choice C rationale
Feeling the baby move, known as "quickening," typically occurs around 18-24 weeks of pregnancy, not 6 weeks. This sensation is different from hearing the heartbeat.
Choice D rationale
While the heart begins to form around week 5, it is not detectable by Doppler at 6 weeks. The technology does not have the sensitivity to detect such an early heartbeat externally.
