Final answer:
Positive signs of pregnancy include identifying a fetal heartbeat, palpating a fetal outline, visualizing the fetus, verifying fetal movement, and a positive hCG test. A regular fetal heartbeat is typically detected around the 6th week of gestation. The most accurate confirmation of pregnancy involves detection of the heartbeat, movement, and visualization of the fetus.
Step-by-step explanation:
The diagnosis of pregnancy is primarily based on positive signs of pregnancy. The positive signs of pregnancy are namely:
- Identification of fetal heartbeat
- Palpation of fetal outline
- Visualization of the fetus
- Verification of fetal movement
- Positive hCG test
During prenatal care, a fetal heartbeat can be detected with technology such as ultrasound or a fetal doppler. According to the stages of fetal development, a regular heartbeat can be detected usually around the 6th week of gestation. However, the most accurate positive signs that affirm pregnancy are fetal heartbeat, fetal movement, and visualization of the fetus confirmed through an ultrasound.
A positive hCG test, which can be done at home, is also a strong indicator, but healthcare professionals rely on these positive signs for a definitive diagnosis of pregnancy.
