1. Which of the following statements is true of Down’s syndrome?

• A. Down’s syndrome is usually caused by an extra copy of chromosome 21 in an individual.
• B. The symptoms of Down’s syndrome are similar to those of sickle-cell anemia.
• C. Down’s syndrome is caused by a sexually transmitted infection (STI) during conception.
• D. The probability of having a child with Down’s syndrome increases with the age of the parents.

Correct answer: D

Rationale: The correct answer is D. The likelihood of having a child with Down’s syndrome increases as the age of the parents increases, particularly the mother's age. Choice A is incorrect because Down’s syndrome is caused by an extra copy of chromosome 21, not a defect in the sex chromosomes. Choice B is incorrect as the symptoms of Down’s syndrome and sickle-cell anemia are different. Choice C is also incorrect as Down’s syndrome is not caused by a sexually transmitted infection during conception.

2. According to a study in the year 2013 by Fellman, if a woman is a twin, if her mother was a twin, or if she has previously borne twins, then:

• A. she will bear only monozygotic (MZ) twins.
• B. the chances of her becoming pregnant decrease.
• C. she is likely to be a healthy mother.
• D. the chances rise that she will bear twins.

Correct answer: D

Rationale: According to the study, the chances of a woman bearing twins increase if she is a twin herself, if her mother was a twin, or if she has previously borne twins. Therefore, the correct answer is D. Choice A is incorrect because the study does not specify that she will bear only monozygotic twins. Choice B is incorrect as the study does not mention any decrease in the chances of becoming pregnant. Choice C is incorrect because the study does not provide information about the woman's health status, focusing instead on the likelihood of bearing twins.

3. When discussing risk factors for gestational diabetes mellitus (GDM) with a group of pregnant clients, which ethnicity should the nurse identify as having the lowest incidence of GDM?

• A. Asian
• B. Non-Hispanic White American
• C. Hispanic
• D. African American

Correct answer: B

Rationale: Non-Hispanic White Americans have the lowest incidence of gestational diabetes mellitus (GDM) compared to other ethnicities. This is because GDM is more prevalent among certain ethnic groups, such as Asian, Hispanic, and African American populations. Asian individuals have an increased risk of developing GDM due to genetic factors, while Hispanic and African American populations have higher incidences of GDM due to lifestyle and genetic predispositions. Therefore, the correct answer is B, as Non-Hispanic White Americans generally have a lower risk of developing GDM.

4. A healthcare professional is planning care for a full-term newborn who is receiving phototherapy. Which of the following actions should the healthcare professional include in the plan of care?

• A. Dress the newborn in lightweight clothing.
• B. Avoid using lotion or ointment on the newborn's skin.
• C. Keep the newborn supine throughout treatment.
• D. Measure the newborn's temperature every 8 hours.

Correct answer: B

Rationale: When a newborn is receiving phototherapy, it is important to avoid using lotions or ointments on their skin as these products can lead to skin irritation and burns under the phototherapy lights. Dressing the newborn in lightweight clothing helps ensure proper exposure to the phototherapy lights. Keeping the newborn supine during treatment helps maximize exposure to the light. However, the key consideration in this scenario is to prevent skin irritation and burns by avoiding lotions or ointments.

5. A woman gave birth to a 7-pound, 6-ounce infant girl 1 hour ago. The birth was vaginal and the estimated blood loss (EBL) was 1500 ml. When evaluating the woman’s vital signs, which finding would be of greatest concern to the nurse?

• A. Temperature 37.9°C, heart rate 120 beats per minute (bpm), respirations 20 breaths per minute, and blood pressure 90/50 mm Hg.
• B. Temperature 37.4°C, heart rate 88 bpm, respirations 36 breaths per minute, and blood pressure 126/68 mm Hg.
• C. Temperature 38°C, heart rate 80 bpm, respirations 16 breaths per minute, and blood pressure 110/80 mm Hg.
• D. Temperature 36.8°C, heart rate 60 bpm, respirations 18 breaths per minute, and blood pressure 140/90 mm Hg.

Correct answer: A

Rationale: An estimated blood loss (EBL) of 1500 ml following a vaginal birth is significant and can lead to hypovolemia. The vital signs provided in option A (Temperature 37.9°C, heart rate 120 bpm, respirations 20 breaths per minute, and blood pressure 90/50 mm Hg) indicate tachycardia and hypotension, which are concerning signs of hypovolemia due to excessive blood loss. Tachycardia is the body's compensatory mechanism to maintain cardiac output in response to decreased blood volume, and hypotension indicates inadequate perfusion. Options B, C, and D do not exhibit the same level of concern for hypovolemia. Option B shows tachypnea, which can be a result of pain or anxiety postpartum. Option C and D have vital signs within normal limits, which are not indicative of the body's response to significant blood loss.
