1. Which best describes a full-thickness (third-degree) burn?

A. Erythema and pain
B. Skin showing erythema followed by blister formation
C. Destruction of all layers of skin evident with extension into subcutaneous tissue
D. Destruction injury involving underlying structures such as muscle, fascia, and bone

Correct answer: C

Rationale: A full-thickness (third-degree) burn involves the destruction of all layers of skin, including the epidermis, dermis, and extending into the subcutaneous tissue. This type of burn results in significant tissue damage and can appear pale, charred, or leathery. Choice A is incorrect as erythema and pain are more characteristic of superficial burns. Choice B describes a partial-thickness burn where the skin shows erythema followed by blister formation, involving the epidermis and part of the dermis. Choice D is incorrect as it describes a deeper type of injury involving structures beyond the skin layers, such as muscle, fascia, and bone, which is not specific to a full-thickness burn.

2. A 6-month-old infant is admitted with a diagnosis of respiratory syncytial virus (RSV). What should the nurse include in the care plan?

A. Providing small, frequent feedings
B. Administering antibiotics
C. Maintaining strict isolation
D. Elevating the head of the bed

Correct answer: D

Rationale: Elevating the head of the bed is essential in the care of an infant with RSV as it helps improve breathing by reducing congestion and promoting drainage. This position also aids in maintaining patent airways and can enhance comfort for the infant. Providing small, frequent feedings (Choice A) is generally appropriate for infants but is not a specific intervention for RSV. Administering antibiotics (Choice B) is not indicated for RSV, as it is a viral infection and antibiotics are ineffective against viruses. Maintaining strict isolation (Choice C) is important to prevent the spread of infections, but it is not a direct care intervention for managing RSV symptoms.

3. The healthcare provider is assessing a family to determine if they have access to adequate health care. Which statement accurately describes how certain families are affected by common barriers to health care?

A. After a decade of escalation, the percentage of children living in low-income families has been declining since 2000.
B. White, non-Hispanic children overall are more likely than African American and Hispanic children to be in very good or excellent health.
C. The proportion of children between the ages of 6 and 18 who are overweight is decreasing, but there is a significant increase in African American females.
D. The overall health care plan of working families may improve access to specialty care but limit access to preventive services.

Correct answer: B

Rationale: Choice B is the correct answer as white, non-Hispanic children are more likely to be in very good or excellent health compared to African American and Hispanic children. This is an important disparity in health outcomes that may be influenced by various social determinants. Choices A, C, and D are incorrect because they do not accurately describe how certain families are affected by common barriers to health care. Choice A discusses the declining percentage of children in low-income families, which is not directly related to barriers to health care. Choice C talks about overweight children and the increase in African American females but does not address access to health care. Choice D discusses the impact of health care plans on working families but does not specifically address barriers to health care access for families.

4. At 0345, you receive a call for a woman in labor. Upon arriving at the scene, you are greeted by a very anxious man who tells you that his wife is having her baby 'now.' This man escorts you into the living room where a 25-year-old woman is lying on the couch in obvious pain. Which of the following statements regarding crowning is true?

A. Crowning represents the end of the second stage of labor.
B. Crowning always occurs immediately after the amniotic sac has ruptured.
C. It is safe to transport the patient during crowning if the hospital is close.
D. Gentle pressure should be applied to the baby's head during crowning.

Correct answer: D

Rationale: During crowning, it is essential to apply gentle pressure to the baby's head to prevent rapid delivery, which can lead to potential injuries to both the mother and the baby. Choice A is incorrect because crowning signifies the beginning, not the end, of the second stage of labor. Choice B is incorrect as crowning can occur before or after the amniotic sac ruptures. Choice C is incorrect as transporting the patient during crowning, even if the hospital is close, can be unsafe due to the risk of rapid delivery and complications.

5. A nurse is teaching the parents of a child with a diagnosis of type 1 diabetes mellitus about insulin administration. What should the nurse emphasize?

A. Rotate injection sites
B. Administer insulin before meals
C. Store insulin in the refrigerator
D. Administer insulin at bedtime

Correct answer: A

Rationale: The correct answer is to rotate injection sites. Rotating injection sites is crucial in insulin administration to prevent lipodystrophy, which is the breakdown of subcutaneous fat at the injection site. It also helps ensure consistent insulin absorption. Administering insulin before meals (choice B) is important to match insulin peak action with the rise in blood glucose after eating. Storing insulin in the refrigerator (choice C) is correct to maintain its potency and stability. Administering insulin at bedtime (choice D) may not be suitable for all patients and is not a universal recommendation for insulin administration.
