1. When should a nurse on a labor and delivery unit instruct a newly licensed nurse to don gloves for a procedure?

• A. Assisting a mother with breastfeeding
• B. Performing a newborn's initial bath
• C. Administering the measles, mumps, rubella vaccine
• D. Performing umbilical cord care

Correct answer: B

Rationale: The correct answer is B: Performing a newborn's initial bath. Gloves should be worn during this procedure to protect against exposure to body fluids, such as amniotic fluid or blood. Assisting a mother with breastfeeding (Choice A) does not typically require gloves unless there are specific reasons for infection control. Administering vaccines (Choice C) and performing umbilical cord care (Choice D) are procedures that may require hand hygiene but not necessarily gloves, unless there is active bleeding or potential exposure to body fluids. The initial bath involves direct contact with body fluids, making it crucial to wear gloves for protection.

2. In the Ballard Gestational Age Assessment Tool, the nurse determines that a 15-month-old infant has a gestational age of 42 weeks. Based on this finding, which intervention is most important for the nurse to implement?

• A. Provide blow-by oxygen
• B. Provide a capillary blood glucose test
• C. Draw arterial blood gases
• D. Apply a pulse oximeter to the foot

Correct answer: B

Rationale: Late preterm infants, such as those with a gestational age of 42 weeks, are at higher risk for hypoglycemia due to immature metabolic regulation. Monitoring capillary blood glucose is crucial to detect and manage hypoglycemia promptly. Providing blow-by oxygen (Choice A) is not indicated for an infant at risk for hypoglycemia. Drawing arterial blood gases (Choice C) is not the primary intervention for assessing hypoglycemia. Applying a pulse oximeter to the foot (Choice D) is not directly related to monitoring blood glucose levels in this context.

3. Chromosomes are _____ structures found in cells.

• A. rod-shaped
• B. circular
• C. cone-shaped
• D. octagonal

Correct answer: A

Rationale: Chromosomes are rod-shaped structures that carry genetic information in the form of DNA. They are typically seen as elongated structures when visualized under a microscope. Choice B, circular, is incorrect as chromosomes do not have a circular shape; they are linear. Choice C, cone-shaped, is not accurate as chromosomes do not resemble cones in any way. Choice D, octagonal, is also incorrect as chromosomes do not have an octagonal appearance. Therefore, the correct answer is A, rod-shaped, which accurately describes the shape of chromosomes.

4. The client who is 40 weeks gestation seems upset and tells the nurse that the physician told her she needs to have a nonstress test. The client asks why she needs the test. The nurse’s best response would be:

• A. This is a test to see if your stress level is affecting your baby’s growth and well-being.
• B. This is a test to see if your baby will be able to withstand the stress of labor.
• C. This is a test to assess your baby’s well-being now that you are due to deliver soon.
• D. This is a test to let us know if your baby needs to be delivered to avoid a bad outcome.

Correct answer: C

Rationale: The correct response is C because the nonstress test is specifically used to assess the baby's well-being close to the due date. It helps determine if the baby is receiving enough oxygen and nutrients in the womb. Choice A is incorrect as the test does not assess the mother's stress level but focuses on fetal well-being. Choice B is incorrect as the test does not predict the baby's ability to withstand labor. Choice D is incorrect because the test does not solely indicate if the baby needs to be delivered to avoid a bad outcome; rather, it assesses the current well-being of the baby.

5. 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.
