The primary clinical manifestation of scabies is:
Maceration
Edema
Itching
Severe pain
The Correct Answer is C
Choice A reason: This statement is incorrect, as maceration is not a clinical manifestation of scabies, but a condition of softening and breaking down of the skin due to prolonged exposure to moisture. Maceration can occur in areas where the skin folds or rubs together, such as the groin, armpits, or under the breasts.
Choice B reason: This statement is incorrect, as edema is not a clinical manifestation of scabies, but a condition of swelling due to excess fluid accumulation in the tissues. Edema can occur in various parts of the body, such as the legs, feet, hands, or face, due to various causes, such as heart failure, kidney disease, or allergic reactions.
Choice C reason: This statement is correct, as itching is the primary clinical manifestation of scabies, a contagious skin infection caused by the mite Sarcoptes scabiei. The mite burrows into the skin and lays eggs, causing an intense inflammatory response and pruritus. The itching is usually worse at night and affects the areas between the fingers, wrists, elbows, armpits, waist, buttocks, and genitals.
Choice D reason: This statement is incorrect, as severe pain is not a clinical manifestation of scabies, but a subjective sensation of physical discomfort or distress. Pain can occur in various parts of the body due to various causes, such as injury, inflammation, infection, or disease. Pain can be acute or chronic, and can be rated on a scale of 0 to 10.

Correct Answer is A
Explanation
Choice A reason: This statement is correct, as hydrostatic reduction of telescoped bowel with an air or saline enema is the preferred treatment for intussusception, which is a condition where a segment of the intestine slides into another segment, causing obstruction, inflammation, and ischemia. The enema can help to push the invaginated bowel back to its normal position, relieve the obstruction, and restore the blood flow. The procedure is safe, effective, and minimally invasive, and can avoid the need for surgery.
Choice B reason: This statement is incorrect, as hydrostatic reduction of telescoped bowel with an air or saline enema is not a false statement, but a true one. The nurse should be aware of the indications, contraindications, and complications of this procedure, and monitor the child's vital signs, abdominal distension, bowel sounds, and stool output before, during, and after the enema. The nurse should also educate the parents about the signs and symptoms of recurrence, such as abdominal pain, vomiting, or bloody stools.
Correct Answer is C
Explanation
Choice A reason: This is incorrect because breastmilk does contain some iron, although not as much as formula. However, the iron in breastmilk is more bioavailable and easily absorbed by the infant. Therefore, iron drops are not necessary for exclusively breast-fed infants until they are 4 to 6 months old.
Choice B reason: This is incorrect because the iron levels of breast-fed infants will start to decline after 4 to 6 months of age, as their iron stores from the mother are used up. Therefore, they will need iron supplementation from other sources, such as iron-fortified cereals or drops.
Choice C reason: This is correct because the iron stores of breast-fed infants are sufficient for the first 4 to 6 months of life, but then they will need additional iron from other sources. Iron supplementation can prevent or treat iron deficiency anemia, which can affect the infant's growth and development.
Choice D reason: This is incorrect because solids are not recommended for infants younger than 4 months of age, as their digestive system is not mature enough to handle them. Solids can also interfere with the intake of breastmilk, which is the main source of nutrition for infants. Iron-rich foods can be introduced after 6 months of age, along with continued breast-feeding.
