Nursing Elites

1. Which of the following pairs share 100% of their genes?

• A. Biovular twins
• B. Fraternal twins
• C. Dizygotic (DZ) twins
• D. Monozygotic (MZ) twins

Correct answer: D

Rationale: The correct answer is Monozygotic (MZ) twins. Monozygotic twins, also known as identical twins, share 100% of their genes because they originate from the same fertilized egg that splits into two. Fraternal twins (choice B), also known as dizygotic (DZ) twins (choice C), result from two separate fertilized eggs and share approximately 50% of their genes. Biovular twins (choice A) is not a term used in genetics and does not describe a type of twinning.

2. A 16-year-old gravida 1 para 0 client has just been admitted to the hospital with a diagnosis of eclampsia. She's not presently convulsing. Which intervention should the nurse plan to include in this client's nursing care plan?

• A. Allow liberal family visitation
• B. Keep an airway at the bedside
• C. Assess temperature every hour
• D. Monitor blood pressure, pulse, and respiration every 4 hours

Correct answer: B

Rationale: Keeping an airway at the bedside is crucial for a client with eclampsia, as there is a high risk of seizures that can obstruct the airway. Allowing liberal family visitation (choice A) may not be a priority at this time and can be overwhelming for the client. Assessing temperature every hour (choice C) is not directly related to managing eclampsia. Monitoring blood pressure, pulse, and respiration every 4 hours (choice D) is important but not as immediate as ensuring airway patency.

3. An individual’s phenotype reflects both genetic and environmental influences.

• A. phenotype
• B. chromosome
• C. allele
• D. genotype

Correct answer: A

Rationale: The correct answer is A: phenotype. A phenotype is the observable characteristics of an individual, which result from the interaction of their genotype with the environment. This interaction between genetics and the environment determines how genes are expressed and how traits are manifested in an individual. Choices B, C, and D are incorrect because chromosomes, alleles, and genotypes are components of an individual's genetic makeup, but they do not directly reflect the observable traits influenced by both genetics and the environment.

4. What is the structure of deoxyribonucleic acid (DNA)?

• A. single spiral
• B. double helix
• C. sphere
• D. cube

Correct answer: B

Rationale: The correct answer is B: double helix. DNA is structured as a double helix, resembling a twisted ladder made up of two strands of nucleotides. Choice A, single spiral, is incorrect as DNA is not a single spiral structure. Choice C, sphere, is incorrect as DNA does not form a spherical shape. Choice D, cube, is incorrect as DNA does not have a cubic structure. Understanding the double helix structure of DNA is essential as it allows for the storage and transmission of genetic information in living organisms.

5. The nurse places one hand above the symphysis while massaging the fundus of a multiparous client whose uterine tone is boggy 15 minutes after delivering a 7-pound, 10-ounce (3220-gram) infant. Which information should the nurse provide to the client about these findings?

• A. The uterus should be firm to prevent an intrauterine infection.
• B. Both the lower uterine segment and the fundus must be massaged.
• C. A firm uterus prevents the endometrial lining from being sloughed.
• D. Clots may form inside a boggy uterus and need to be expelled.

Correct answer: D

Rationale: After childbirth, a boggy uterus indicates poor uterine tone, which can lead to the formation of clots. Massaging the fundus helps the uterus contract and expel clots, reducing the risk of postpartum hemorrhage. Choices A, B, and C are incorrect because the main concern with a boggy uterus is the risk of clot formation and postpartum hemorrhage, not solely preventing intrauterine infection, massaging the lower uterine segment, or preventing the endometrial lining from sloughing.
