The nurse teaches a pregnant woman about the presumptive, probable, and positive signs of pregnancy. The woman demonstrates understanding of the nurse's instructions if she states that a positive sign of pregnancy is:
- A. a positive pregnancy test.
- B. fetal movement palpated by the nurse-midwife.
- C. Braxton Hicks contractions.
- D. quickening.
Correct Answer: B
Rationale: Positive signs of pregnancy are attributed to the presence of a fetus, such as hearing the fetal heartbeat or palpating fetal movement.

Which statement about a condition of pregnancy is accurate?
- A. Insufficient salivation (ptyalism) is caused by increases in estrogen.
- B. Acid indigestion (pyrosis) begins early but declines throughout pregnancy.
- C. Hyperthyroidism often develops (temporarily) because hormone production increases.
- D. Nausea and vomiting rarely have harmful effects on the fetus and may be beneficial.
Correct Answer: C
Rationale: The correct answer is C because hyperthyroidism can indeed develop during pregnancy due to the increase in hormone production, specifically human chorionic gonadotropin (hCG) stimulating the thyroid gland. This can lead to symptoms such as weight loss, anxiety, and palpitations. Other choices are incorrect because A is false - ptyalism is actually linked to progesterone levels, not estrogen. B is incorrect because acid indigestion tends to worsen as pregnancy progresses, not decline. D is incorrect as severe nausea and vomiting, known as hyperemesis gravidarum, can have harmful effects on both the mother and fetus if not properly managed.
Which comment made by a new mother exhibits understanding of her toddler's response to a new sibling?
- A. "I can't believe he is sucking his thumb again."
- B. "He is being difficult and I don't have time to deal with him."
- C. "When we brought the baby home, we made Michael stop sleeping in the crib
- D. "My husband is going to stay with the baby so I can take Michael to the park tomorrow."
Correct Answer: E
Rationale: I'm sorry, but the question you provided does not have an option E. Could you please provide the correct multiple-choice options for me to analyze and provide a detailed explanation of the correct answer?
A nurse is reviewing the laboratory results for a prenatal client. She notices that her hemoglobin is 10.5. The nurse realizes this laboratory result indicates which of the following?
- A. Low vitamin intake has resulted in a decrease in red blood cell production.
- B. Plasma volume increase is greater than red blood cell production and has resulted in a decrease in hemoglobin.
- C. This is a serious problem that might harm the fetus.
- D. A repeat blood test should be done immediately to confirm that the client has anemia
Correct Answer: B
Rationale: The correct answer is B because a hemoglobin level of 10.5 indicates a decrease in hemoglobin concentration, which is typically caused by an increase in plasma volume during pregnancy. This dilution effect results in a lower concentration of red blood cells in the blood, leading to lower hemoglobin levels. This physiological change is normal during pregnancy and is known as physiological anemia.
Choice A is incorrect because low vitamin intake would not directly result in a decrease in red blood cell production leading to low hemoglobin levels.
Choice C is incorrect because a hemoglobin level of 10.5, although lower than normal, does not necessarily indicate a serious problem that would harm the fetus.
Choice D is incorrect because a repeat blood test is not immediately necessary to confirm anemia as the low hemoglobin level can be explained by the normal increase in plasma volume during pregnancy.
The diagnosis of pregnancy is based on which positive signs of pregnancy? (Select all that apply.)
- A. Identification of fetal heartbeat
- B. Palpation of fetal outline
- C. Visualization of the fetus
- D. Verification of fetal movement
Correct Answer: A
Rationale: Step-by-step rationale for choice A (Identification of fetal heartbeat) being correct:
1. Detection of fetal heartbeat confirms the presence of a developing fetus.
2. It is a definitive sign of pregnancy and indicates fetal viability.
3. Fetal heartbeat can be detected using ultrasound or Doppler.
4. This sign is not subject to interpretation or misinterpretation.
Summary of why the other choices are incorrect:
- Choice B (Palpation of fetal outline) and D (Verification of fetal movement) are considered probable signs of pregnancy and do not provide definitive confirmation.
- Choice C (Visualization of the fetus) is not a reliable sign as it requires advanced imaging techniques and can be subjective.
To reassure and educate pregnant patients about the functioning of their kidneys in eliminating waste products, maternity nurses should be aware that:
- A. increased urinary output makes pregnant women less susceptible to urinary infection
- B. increased bladder sensitivity and then compression of the bladder by the enlarging uterus results in the urge to urinate even if the bladder is almost empty
- C. renal (kidney) function is more efficient when the woman assumes a supine position
- D. using diuretics during pregnancy can help keep kidney function regular
Correct Answer: B
Rationale: Bladder sensitivity and compression by the uterus cause frequent urination. Pregnant women are more susceptible to urinary tract infections, and lateral positions improve renal efficiency.
