Nursing Elites

1. A healthcare provider is assessing a preterm newborn who is at 32 weeks of gestation. Which of the following finding should the healthcare provider expect?

• A. Minimal arm recoil
• B. Popliteal angle of less than 90°
• C. Creases over the entire sole
• D. Sparse lanugo

Correct answer: A

Rationale: When assessing a preterm newborn at 32 weeks of gestation, healthcare providers should expect minimal arm recoil. This finding is common in preterm infants due to lower muscle tone. Choice B, a popliteal angle of less than 90°, is incorrect for this age group. Creases over the entire sole (Choice C) typically develop at term age, not at 32 weeks of gestation. Sparse lanugo (Choice D) is a normal finding in preterm infants but is not specific to those at 32 weeks of gestation.

2. What is the highest priority nursing intervention when admitting a pregnant woman who has experienced a bleeding episode in late pregnancy?

• A. Assessing FHR and maternal vital signs.
• B. Performing a venipuncture for hemoglobin and hematocrit levels.
• C. Placing clean disposable pads to collect any drainage.
• D. Monitoring uterine contractions.

Correct answer: A

Rationale: The highest priority nursing intervention when admitting a pregnant woman who has experienced a bleeding episode in late pregnancy is to assess the fetal heart rate (FHR) and maternal vital signs. This assessment is crucial in determining the extent of blood loss and its impact on both the mother and the fetus. Ensuring the well-being of both the mother and the fetus is the top priority in this situation. While obtaining hemoglobin and hematocrit levels is important, it can be done after the initial assessment. Placing clean disposable pads is necessary for managing any drainage but does not take precedence over assessing vital signs. Monitoring uterine contractions is important but is not the highest priority when compared to assessing the FHR and maternal vital signs.

3. Once the testes have developed in the embryo, they begin to produce male sex hormones, or _____.

• A. androgens
• B. genotypes
• C. blastocysts
• D. teratogens

Correct answer: A

Rationale: Androgens are male sex hormones, such as testosterone, produced by the testes after they have developed in the embryo. Androgens are responsible for the development of male secondary sexual characteristics. Genotypes refer to an individual's genetic makeup, not hormones. Blastocysts are early stage embryos, not male sex hormones. Teratogens are substances that can interfere with fetal development, not male sex hormones produced by the testes.

4. A nurse is developing an educational program about hemolytic diseases in newborns for a group of newly licensed nurses. Which of the following genetic information should the nurse include in the program as a cause of hemolytic disease?

• A. The mother is Rh positive, and the father is Rh negative
• B. The mother is Rh negative, and the father is Rh positive
• C. The mother and the father are both Rh positive
• D. The mother and the father are both Rh negative

Correct answer: B

Rationale: The correct answer is B: 'The mother is Rh negative, and the father is Rh positive.' Hemolytic disease of the newborn occurs when an Rh-negative mother carries an Rh-positive fetus, leading to Rh incompatibility. In this scenario, the mother produces antibodies against the Rh antigen present in the fetus, which can result in hemolysis of the fetal red blood cells. Choices A, C, and D do not describe the Rh incompatibility that leads to hemolytic disease in newborns. Therefore, they are incorrect.

5. Monozygotic (MZ) twins share _________ percent of their genes.

• A. 100
• B. 75
• C. 50
• D. 25

Correct answer: A

Rationale: Monozygotic (MZ) twins share 100% of their genes because they originate from the same fertilized egg that splits into two, resulting in identical genetic material for both twins. Choice B (75%) is incorrect as it implies a partial genetic similarity, which is not the case for MZ twins. Choice C (50%) is incorrect as it suggests half of the genes are shared, which is applicable to dizygotic (DZ) twins, not MZ. Choice D (25%) is incorrect as it indicates minimal genetic sharing, which is not true for MZ twins.
