Iron deficiency anemia often occurs during pregnancy as a result of

Decreased production of erythrocytes

Inadequate intake of iron

Dilution of hemoglobin concentration

The fetus establishing iron stores

Answer and Explanation

The Correct Answer is B

Choice A: Decreased production of erythrocytes

This is not the primary cause of iron deficiency anemia during pregnancy. While erythrocyte production may be affected in certain conditions, it is not directly linked to iron deficiency anemia in pregnancy¹.

Choice B: Inadequate intake of iron

This is the correct answer. During pregnancy, the body needs more iron to make hemoglobin for the increased volume of blood. If the intake of iron is not sufficient, it could lead to iron deficiency anemia¹.

Choice C: Dilution of hemoglobin concentration

While it's true that the blood volume increases during pregnancy, leading to a relative dilution of hemoglobin, this is not the primary cause of iron deficiency anemia. The main issue is the lack of sufficient iron intake¹.

Choice D: The fetus establishing iron stores

While the fetus does require iron, which it gets from the mother, this is not the primary cause of iron deficiency anemia during pregnancy. The main issue is still the mother's inadequate intake of iron¹.

Correct Answer is C

Explanation

Choice A reason: A biophysical profile score of 8 is a good indicator of fetal well-being, but it does not measure the fetal lung maturity. It consists of five parameters: fetal breathing movements, fetal movements, fetal tone, amniotic fluid volume, and nonstress test.

Choice B reason: Phosphatidylglycerol (PG) is a phospholipid that is present in the fetal lung surfactant. Its presence indicates that the fetal lungs are mature, while its absence does not rule out the possibility of maturity.

Choice C reason: Lecithin and sphingomyelin are two phospholipids that are found in the fetal lung surfactant. The L/S ratio is the ratio of lecithin to sphingomyelin in the amniotic fluid. A ratio of 2:1 or higher indicates that the fetal lungs are mature and can produce enough surfactant to prevent respiratory distress syndrome.

Choice D reason: A nonstress test is a test that measures the fetal heart rate and its response to fetal movements. A reactive test means that the fetal heart rate increases by at least 15 beats per minute for at least 15 seconds twice in a 20-minute period. This indicates that the fetus is healthy and well-oxygenated, but it does not reflect the fetal lung maturity.

A. None of the above B. Staying about the same C. Going down D. Rising E. The correct answer is d. Rising.

Correct Answer is D

Explanation

Choice A reason: None of the above is incorrect because the other choices are not true statements about the overall number of cases of STIs.

Choice B reason: Staying about the same is incorrect because the overall number of cases of STIs is not constant. According to the World Health Organization, more than 1 million STIs are acquired every day worldwide.

Choice C reason: Going down is incorrect because the overall number of cases of STIs is not decreasing. On the contrary, some STIs such as syphilis, gonorrhea, and chlamydia are resurging in many regions due to factors such as antimicrobial resistance, lack of access to prevention and treatment services, and stigma.

Choice D reason: Rising is correct because the overall number of cases of STIs is increasing globally. The World Health Organization estimates that there were 376 million new cases of four curable STIs (chlamydia, gonorrhea, syphilis, and trichomoniasis) in 2016, up from 357 million in 2012. Additionally, there are millions of cases of incurable STIs such as herpes, HPV, and HIV that affect the health and well-being of people worldwide.
