Which of the following is a positive sign of pregnancy that can only be exhibited by a pregnant woman?

Fetal heartbeat auscultated with Doppler/fetoscope.

Quickening

Morning sickness

Positive pregnancy test

Answer and Explanation

The Correct Answer is A

Choice A reason: A fetal heartbeat auscultated with a Doppler or a fetoscope is a positive sign of pregnancy, as it confirms the presence of a living fetus in the uterus. A Doppler is an electronic device that uses sound waves to detect the fetal heart rate, while a fetoscope is a stethoscope-like instrument that amplifies the fetal heart sounds. The fetal heartbeat can be heard as early as 10 to 12 weeks of gestation with a Doppler and 18 to 20 weeks of gestation with a fetoscope.

Choice B reason: Quickening is the first perception of fetal movement by the pregnant woman, usually felt between 16 and 20 weeks of gestation for first-time mothers and 13 to 16 weeks of gestation for experienced mothers. However, quickening is not a positive sign of pregnancy, as it can be subjective and mistaken for other sensations, such as gas, hunger, or muscle spasms².

Choice C reason: Morning sickness is a common symptom of pregnancy that involves nausea and vomiting, usually in the first trimester. However, morning sickness is not a positive sign of pregnancy, as it can be caused by other factors, such as food poisoning, stress, or medication.

Choice D reason: A positive pregnancy test is a probable sign of pregnancy, not a positive sign. A pregnancy test detects the presence of human chorionic gonadotropin (hCG), a hormone produced by the placenta, in the urine or blood of the woman. However, a positive pregnancy test does not guarantee a viable pregnancy, as it can be influenced by the timing, the quality, or the interpretation of the test. A positive pregnancy test can also occur in cases of ectopic pregnancy, molar pregnancy, or miscarriage.

Correct Answer is B

Explanation

Choice A reason: Human immunodeficiency virus (HIV) is a viral sexually transmitted infection that causes acquired immunodeficiency syndrome (AIDS). It is characterized by a progressive decline of the immune system, leading to opportunistic infections and cancers. It does not have recurrent episodes, but rather a chronic and incurable course.

Choice B reason: Herpes simplex virus (HSV)-2 is a viral sexually transmitted infection that causes genital herpes. It is characterized by a primary infection followed by recurrent episodes of painful blisters and ulcers in the genital area. The virus remains latent in the nerve cells and can reactivate periodically or in response to triggers such as stress, illness, or menstruation.

Choice C reason: Human papillomavirus (HPV) is a viral sexually transmitted infection that causes genital warts and cervical cancer. It is characterized by a persistent infection that may or may not produce symptoms. It does not have recurrent episodes, but rather a variable and unpredictable course.

Choice D reason: Cytomegalovirus (CMV) is a viral sexually transmitted infection that causes mild or asymptomatic infections in healthy adults. It is characterized by a latent infection that can reactivate in immunocompromised individuals, causing serious complications such as retinitis, pneumonia, or encephalitis. It does not have recurrent episodes, but rather a dormant and opportunistic course.

A. progesterone. B. testosterone. C. prolactin. D. estrogen.

Correct Answer is A

Explanation

Choice A reason: Progesterone is the hormone that stimulates the development of the alveoli and lobules of the mammary glands during pregnancy. It prepares the breasts for lactation by increasing the number and size of the milk-producing cells.

Choice B reason: Testosterone is the main male sex hormone that is responsible for the development of male reproductive organs and secondary sex characteristics. It has no direct role in the maturation of mammary gland tissue.

Choice C reason: Prolactin is the hormone that initiates and maintains milk production after childbirth. It is secreted by the anterior pituitary gland in response to suckling or nipple stimulation. It does not affect the maturation of mammary gland tissue.

Choice D reason: Estrogen is the hormone that stimulates the growth of the duct system of the mammary glands during puberty and pregnancy. It also promotes the development of female reproductive organs and secondary sex characteristics. It does not affect the maturation of mammary gland tissue.
