Nursing Elites

1. Following a traumatic delivery, an infant receives an initial Apgar score of 3. Which intervention is most important for the nurse to implement?

• A. Page the pediatrician STAT
• B. Continue resuscitative efforts
• C. Repeat the Apgar assessment in 5 minutes
• D. Inform the parents of the infant's condition

Correct answer: B

Rationale: In a situation where an infant receives a low Apgar score of 3 following a traumatic delivery, the most crucial intervention for the nurse to implement is to continue resuscitative efforts. A low Apgar score indicates that the newborn is in distress and requires immediate medical attention to support breathing, heart rate, muscle tone, reflex irritability, and color. Continuing resuscitative efforts is essential to provide life-saving interventions promptly. Paging the pediatrician may cause a delay in crucial interventions, repeating the Apgar assessment in 5 minutes is not appropriate as immediate action is needed to stabilize the infant, and informing parents should not take precedence over providing immediate medical care to the newborn.

2. How many pairs of autosomes does a human zygote contain?

• A. 46
• B. 44
• C. 23
• D. 22

Correct answer: D

Rationale: A human zygote contains 22 pairs of autosomes and one pair of sex chromosomes, totaling 46 chromosomes. Therefore, the correct answer is 22. Choices A, B, and C are incorrect because they do not accurately represent the number of autosomes in a human zygote. Option A (46) represents the total number of chromosomes in a human zygote, not the number of autosomes. Option B (44) is incorrect as it does not account for the correct number of autosomes. Option C (23) is inaccurate since it represents the total number of chromosomes in a human gamete, not the number of autosomes in a zygote.

3. After mitosis, the genetic code is identical in new cells unless _________ occur through radiation or other environmental influences.

• A. reductions
• B. expulsions
• C. conceptions
• D. mutations

Correct answer: D

Rationale: After mitosis, the genetic code is typically preserved and remains identical in the new cells. However, mutations can occur due to radiation or environmental influences, leading to changes in the DNA sequence and potentially altering the genetic code. Therefore, the correct answer is 'mutations.' Choices A, B, and C are incorrect because reductions, expulsions, and conceptions do not accurately describe the changes in the genetic code that can result from external factors. Mutations are the only option that reflects the alteration in the genetic code caused by external influences, making it the correct choice in this context.

4. Which of the following is a sexually transmitted infection that, in advanced stages, can attack major organ systems?

• A. Rubella
• B. Syphilis
• C. Cystic fibrosis
• D. Phenylketonuria

Correct answer: B

Rationale: Syphilis is the correct answer. Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum. If left untreated, it can progress through various stages and potentially attack major organ systems, causing severe complications. Rubella, Cystic fibrosis, and Phenylketonuria are not sexually transmitted infections. Rubella is a viral infection, Cystic fibrosis is a genetic disorder affecting the lungs and digestive system, and Phenylketonuria is a genetic metabolic disorder. These conditions do not typically affect major organ systems in the same way as untreated syphilis.

5. 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.
