Which time-based description of a stage of development in pregnancy is accurate?

  • A. Viability-22 to 37 weeks since the last menstrual period (LMP) (assuming a fetal weight >500 g).
  • B. Full Term-Pregnancy from the beginning of week 39 of gestation to the end of week 40
  • C. Preterm-Pregnancy from 20 to 28 weeks.
  • D. Postdate-Pregnancy that extends beyond 38 weeks.
Correct Answer: B

Rationale: The correct answer is B: Full Term-Pregnancy from the beginning of week 39 of gestation to the end of week 40. This is accurate because full-term pregnancy typically ranges from 39 to 40 weeks of gestation, which is considered the optimal time for a baby to be born in terms of development and health. Viability (Choice A) refers to the ability of a fetus to survive outside the womb and typically occurs between 22 to 37 weeks. Preterm (Choice C) describes a pregnancy that occurs before 37 weeks. Postdate (Choice D) refers to a pregnancy that extends beyond 40 weeks. Therefore, Choices A, C, and D are incorrect as they do not accurately describe the full-term stage of pregnancy.

Which finding in the urine analysis of a pregnant woman is considered a variation of normal?

  • A. Proteinuria
  • B. Glycosuria
  • C. Bacteria in the urine
  • D. Ketones in the urine
Correct Answer: B

Rationale: The correct answer is B: Glycosuria. In pregnant women, glycosuria is considered a variation of normal due to the hormonal changes affecting glucose metabolism. During pregnancy, the renal threshold for glucose is lowered, leading to glucose spillage in urine without significant pathology. Proteinuria (A) can indicate kidney damage. Bacteria in the urine (C) suggest a possible urinary tract infection. Ketones in the urine (D) may indicate a metabolic disorder or inadequate carbohydrate intake. Glycosuria in pregnancy is a physiological adaptation and not necessarily a cause for concern.
