1. Most victims of _____ die of respiratory infections in their 20s.
- A. Tay-Sachs disease
- B. cystic fibrosis
- C. Turner syndrome
- D. Klinefelter syndrome
Correct answer: B
Rationale: Individuals with cystic fibrosis have a genetic disorder that causes mucus to be thick and sticky, leading to blockages in the lungs and digestive system. This mucus buildup makes them more susceptible to severe respiratory infections, which can ultimately result in premature death in their 20s. Tay-Sachs disease (Choice A) is a genetic disorder that affects the nervous system, not typically causing respiratory infections. Turner syndrome (Choice C) and Klinefelter syndrome (Choice D) are chromosomal disorders that do not directly lead to the respiratory issues observed in cystic fibrosis.
2. A multiparous client at 36 hours postpartum reports increased bleeding and cramping. On examination, the nurse finds the uterine fundus 2 centimeters above the umbilicus. Which action should the nurse take first?
- A. Increase the intravenous fluid to 150 ml/hr.
- B. Call the healthcare provider.
- C. Encourage the client to void.
- D. Administer ibuprofen 800 milligrams by mouth.
Correct answer: C
Rationale: Encouraging the client to void is the priority action in this scenario. A distended bladder can prevent the uterus from contracting properly, leading to increased bleeding and a high uterine fundus. By encouraging the client to void, the nurse can help the uterus contract effectively, reducing bleeding. Increasing intravenous fluids or administering ibuprofen would not address the immediate concern of a distended bladder affecting uterine contraction. While it may be necessary to involve the healthcare provider, addressing the bladder distention promptly is crucial to prevent further complications.
3. A client who is receiving prenatal care is at her 24-week appointment. Which of the following laboratory tests should the nurse plan to conduct?
- A. Group B strep culture
- B. 1-hour glucose tolerance test
- C. Rubella titer
- D. Blood type and Rh
Correct answer: B
Rationale: The correct answer is B: 1-hour glucose tolerance test. At around 24-28 weeks of gestation, a pregnant individual is typically screened for gestational diabetes. The 1-hour glucose tolerance test helps in identifying elevated blood sugar levels during pregnancy. Choice A, Group B strep culture, is not typically performed at the 24-week appointment but later in the third trimester to screen for Group B streptococcus colonization. Choice C, Rubella titer, is usually checked early in pregnancy to determine immunity to rubella. Choice D, Blood type and Rh, is important for determining the client's blood type and Rh status, but it is usually done earlier in pregnancy and not specifically at the 24-week appointment.
4. When do mothers usually feel the first fetal movements during pregnancy?
- A. At 18-20 weeks
- B. During the first month
- C. Rarely
- D. Never
Correct answer: A
Rationale: Mothers usually feel the first fetal movements, known as 'quickening,' around the 18th to 20th week of pregnancy. Feeling fetal movements during the first month is unlikely and uncommon. Therefore, option B is incorrect. Options C and D are also incorrect as mothers typically do feel fetal movements during pregnancy, just not during the first month.
5. Dizygotic (DZ) twins share _________ percent of their genes.
- A. 100
- B. 75
- C. 50
- D. 25
Correct answer: C
Rationale: Dizygotic (DZ) twins share approximately 50% of their genes. This is because dizygotic twins, also known as fraternal twins, originate from two separate fertilized eggs and share similar genetic similarity to regular siblings. Choice A (100%) is incorrect because if twins shared 100% of their genes, they would be identical twins (monozygotic). Choice B (75%) is incorrect as it is not the typical genetic similarity seen in dizygotic twins. Choice D (25%) is incorrect as it represents a significantly lower genetic similarity than what is observed in dizygotic twins.
