Nursing Elites

1. What causes cystic fibrosis?

• A. Sex-linked abnormality.
• B. Abnormality in the 21st pair of chromosomes.
• C. Recessive gene.
• D. Single segment found only on the Y chromosome.

Correct answer: C

Rationale: Cystic fibrosis is a genetic disorder caused by inheriting two copies of a recessive gene, one from each parent. This means that both parents must carry at least one copy of the faulty gene for a child to inherit the condition. Choice A is incorrect because cystic fibrosis is not linked to the sex chromosomes. Choice B is incorrect as cystic fibrosis is not caused by an abnormality in the 21st pair of chromosomes but by a specific gene mutation. Choice D is also incorrect as cystic fibrosis is not related to the Y chromosome, which is specific to males.

2. What information should the nurse include when teaching a client at 41 weeks of gestation about a non-stress test?

• A. This test will confirm fetal lung maturity.
• B. This test will determine the adequacy of placental perfusion.
• C. This test will detect fetal infection.
• D. This test will predict maternal readiness for labor.

Correct answer: B

Rationale: The correct answer is B: 'This test will determine the adequacy of placental perfusion.' The non-stress test is used to assess fetal well-being by monitoring the fetal heart rate in response to its own movements. It helps determine if the fetus is receiving enough oxygen and nutrients through placental perfusion. Choice A is incorrect because confirming fetal lung maturity is typically determined through tests like amniocentesis, not the non-stress test. Choice C is incorrect because detecting fetal infection is not the primary purpose of a non-stress test. Choice D is incorrect because predicting maternal readiness for labor is not the purpose of the non-stress test; it focuses on fetal well-being.

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. A multiparous woman has been in labor for 8 hours. Her membranes have just ruptured. What is the nurse’s highest priority in this situation?

• A. Prepare the woman for imminent birth.
• B. Notify the woman’s primary healthcare provider.
• C. Document the characteristics of the fluid.
• D. Assess the fetal heart rate (FHR) and pattern.

Correct answer: D

Rationale: The correct answer is to assess the fetal heart rate (FHR) and pattern (Choice D). When a multiparous woman's membranes rupture after 8 hours of labor, the nurse's priority is to assess the fetal well-being. Rupture of membranes can lead to potential complications such as umbilical cord prolapse. Monitoring the fetal heart rate and pattern immediately after the rupture of membranes is crucial to ensure the fetus is not in distress. This assessment helps in determining the need for immediate interventions to safeguard the fetus. Documenting the characteristics of the fluid (Choice C) may be necessary but is of lower priority compared to assessing fetal well-being. While preparing the woman for imminent birth (Choice A) is important, assessing the fetal heart rate takes precedence to ensure the fetus is not compromised. Notifying the woman's primary healthcare provider (Choice B) is also important but not the highest priority at this moment.

5. _________ is self-propulsion.

• A. Mitosis
• B. Meiosis
• C. Motility
• D. Mutation

Correct answer: C

Rationale: The correct answer is 'Motility.' Motility refers to the ability of cells or organisms to move by themselves, often through the use of specialized structures like flagella or cilia. Mitosis (Choice A) and Meiosis (Choice B) are processes related to cell division and genetic recombination, respectively, not self-propulsion. Mutation (Choice D) refers to changes in the DNA sequence and is not related to self-propulsion.
