An 18-month-old is admitted to the hospital for full-thickness burns to the anterior chest. The mother asks how the burn will heal. Which statement is accurate about healing of full-thickness burns?
Surgical closure and graft are usually needed.
Healing takes 10-12 days, with little to no scarring.
Healing can take up to six weeks, with a high incidence of scaring.
Pigment in dark-skinned individuals will return to the area.
The Correct Answer is A
Rationale:
A. Full-thickness burns destroy all layers of the skin and do not regenerate on their own. Surgical intervention, including excision and skin grafting, is typically required for healing.
B. This timeframe and lack of scarring are characteristic of superficial or superficial partial-thickness burns, not full-thickness.
C. While healing may take longer without grafting, surgical closure is standard due to the inability of full-thickness burns to heal naturally.
D. Pigment usually does not return fully in grafted or deeply burned areas, especially in individuals with darker skin tones. Permanent discoloration or hypopigmentation is common.

Correct Answer is C
Explanation
Rationale:
A. A metabolic screening test does not assess the metabolic rate.
B. Emotional or psychological disorders are not detected through newborn metabolic screening.
C. Newborn metabolic screening is a vital test that checks for numerous rare, but serious inherited metabolic and genetic disorders, such as phenylketonuria (PKU), congenital hypothyroidism, galactosemia, and others. Early detection allows for prompt treatment to prevent severe complications like intellectual disability, organ damage, or death.
D. While infections can affect development, they are not the primary focus of the newborn metabolic screening test.
Correct Answer is B
Explanation
Rationale:
A. NPH is an intermediate-acting insulin and is not suitable for insulin pumps due to its unpredictable absorption and tendency to clog pump tubing.
B. Regular insulin is a short-acting insulin and is commonly used in insulin pumps because it has a predictable onset and duration, allowing for precise dosing.
C. Glargine is a long-acting insulin and cannot be delivered via an insulin pump, which requires rapid or short-acting insulins.
D. Premixed regular and NPH insulin is not used in pumps due to the combination of insulins with different action profiles and risks of clogging the device.
