The cheese-like, whitish substance that fuses with the epidermis and serves as a protective coating is called:
Vernix caseosa
Surfactant
Caput succedaneum
Acrocyanosis
The Correct Answer is A
Vernix caseosa is a cheese-like, whitish substance that fuses with the epidermis and serves as a protective coating for the newborn.
Some possible explanations for the other choices are:
- Choice B. Surfactant is a protein that lines the alveoli of the infant’s lungs and helps prevent them from collapsing.
- Choice C. Caput succedaneum is a swelling of the tissue over the presenting part of the fetal head caused by pressure during delivery.
- Choice D. Acrocyanosis is a bluish discoloration of the hands and feet due to reduced peripheral circulation.
Normal ranges for vernix caseosa are not applicable as it varies depending on the gestational age and skin maturity of the newborn. However, it is usually more abundant in preterm infants than in term or post-term infants.

Correct Answer is D
Explanation
Give small amounts of favorite fluids frequently to prevent dehydration.
Dehydration is a common complication of upper respiratory tract infections in infants, especially if they have a fever. Giving small amounts of fluids frequently can help maintain hydration and electrolyte balance.
Some additional information about the other choices are:
Choice A is wrong because tepid water baths are not recommended for fever reduction. They can cause shivering, which increases heat production and can raise the
temperature further. Instead, antipyretics such as acetaminophen or ibuprofen can be given as prescribed.
Choice B is wrong because food intake may be decreased due to poor appetite, difficulty breathing, or sore throat. Forcing food intake can cause vomiting or aspiration. Fluid intake is more important than caloric intake during an acute infection.
Choice C is wrong because heavy clothing can increase heat retention and discomfort. The infant should be dressed in light clothing and the room temperature should be comfortable.
Correct Answer is A
Explanation
This is a normal respiratory change in pregnancy caused by elevated levels of estrogen. Estrogen increases blood flow and causes the nasal mucosa to swell, leading to congestion and nosebleeds. This condition is called pregnancy rhinitis and affects up to 20% of pregnant women.
Choice B is wrong because this is not an abnormal cardiovascular change, and the nosebleeds are not an ominous sign. They are usually harmless and do not affect the pregnancy outcome.
Choice C is wrong because there is no evidence that the woman is a victim of domestic violence.
This is a serious accusation that should not be made without proper assessment and screening.
Choice D is wrong because there is no indication that the woman has been using cocaine intranasally. Cocaine use can cause nasal damage and bleeding, but it can also have other signs and symptoms such as agitation, euphoria, dilated pupils, increased heart rate and blood pressure, and risk of miscarriage or preterm labor.
