A young woman comes to the neighborhood clinic explaining that she had a negative urine pregnancy test last week but a positive test today. What is the best explanation?

  • A. It is probable that the hCG levels were not high enough to be detected last week.
  • B. It is likely that you may not be pregnant, so wait to see if you get your period.
  • C. Don't worry, this happens sometimes. You should perform another test in a few days.
  • D. Shall we set up a complete examination to see if you are really pregnant?
Correct Answer: A

Rationale: The correct answer is A: It is probable that the hCG levels were not high enough to be detected last week. This is because hCG (human chorionic gonadotropin) is the hormone produced during pregnancy that is detected in pregnancy tests. In early pregnancy, hCG levels can be low and may not be detectable by a urine test until they reach a certain threshold. Therefore, a negative test last week could be due to the hCG levels being below the detection threshold at that time. A positive test today indicates that the hCG levels have increased and are now detectable.

Summary of why the other choices are incorrect:
B: It is likely that you may not be pregnant, so wait to see if you get your period. This is incorrect because a positive test indicates pregnancy, and waiting for a period may not be appropriate if the woman is indeed pregnant.
C: Don't worry, this happens sometimes. You should perform another test in a few days. This

Numerous changes in the integumentary system occur during pregnancy. Which change persists after birth?

  • A. Epulis
  • B. Chloasma
  • C. Telangiectasia
  • D. Striae gravidarum
Correct Answer: D

Rationale: The correct answer is D, Striae gravidarum, because it refers to stretch marks that occur during pregnancy and often persist postpartum. Epulis (A) is a benign gingival tumor that typically resolves after pregnancy. Chloasma (B) is a skin condition causing dark patches that usually fade postpartum. Telangiectasia (C) are small dilated blood vessels that commonly appear during pregnancy but may diminish after giving birth. Therefore, the key differentiator is the persistence of Striae gravidarum after delivery.

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.

  • A. A sac-like organ made of skin and muscles that houses the testes
  • B. The external urethral orifice located at the tip of the penis
  • C. The male gonads responsible for the production of sperm and testosterone
  • D. A walnut-sized exocrine gland that borders the inferior end of the urinary bladder and surrounds the urethra
Correct Answer: A

Rationale: The scrotum is a pouch of skin and muscle that protects and regulates the temperature of the testes.
