Jana purchased an over-the-counter pregnancy test.
The results were positive.
The hormone responsible for a positive pregnancy test is:
Testosterone.
Progesterone.
Human Chorionic Gonadotropin (HCG).
Estrogen.
The Correct Answer is C
Choice A rationale
Testosterone is primarily a male hormone and does not play a role in pregnancy detection. Its presence would not indicate pregnancy or contribute to a positive pregnancy test result.
Choice B rationale
Progesterone supports pregnancy by maintaining the uterine lining but is not the hormone detected by pregnancy tests. Its levels do rise in pregnancy, but it is not used as a marker for detection.
Choice C rationale
Human Chorionic Gonadotropin (HCG) is produced by the placenta shortly after fertilization. Its presence in urine or blood is the basis for positive pregnancy test results. Normal HCG levels rise rapidly in early pregnancy.
Choice D rationale
Estrogen levels increase during pregnancy, but like progesterone, it is not used for pregnancy detection. Estrogen supports various pregnancy-related functions but is not detected in pregnancy tests.

Correct Answer is A
Explanation
Choice A rationale
Mild contractions and minimal cervical dilation suggest false labor. Administering a sedative helps the patient rest and wait for true labor onset. Sedatives can include sleep-inducing medications.
Choice B rationale
Cesarean birth is not indicated for a primigravida with mild contractions and minimal cervical dilation. This intervention is reserved for more serious obstetric complications.
Choice C rationale
Extended observation is unnecessary for mild contractions and unchanged cervical status. It is more appropriate for patients showing signs of true labor or complications.
Choice D rationale
True labor onset requires regular, increasing intensity contractions and cervical changes. Discharging the patient allows her to await true labor onset at home comfortably.
Correct Answer is B
Explanation
Choice A rationale
Although the placenta acts as a partial barrier, it does not keep out all harmful substances, allowing some to cross and affect fetal development.
Choice B rationale
One of the placenta's early functions is producing hormones like human chorionic gonadotropin (hCG), estrogen, and progesterone, making it act as an endocrine gland.
Choice C rationale
The placenta does not thin out; it remains robust and increases in thickness to support the growing fetus and facilitate nutrient and gas exchange.
Choice D rationale
While optimal blood circulation through the placenta is crucial, this statement lacks detail on the specific structural and functional aspects of the placenta.
