Question 1 of 5
What is the hallmark sign of intussusception?
Correct Answer: B
Rationale: The hallmark sign of intussusception is currant jelly-like stools, which result from the mixture of blood and mucus in the stool due to the sloughing of intestinal mucosa. Mucus-like stools (Choice A) are not typically associated with intussusception. Tarry, black stools (Choice C) are characteristic of gastrointestinal bleeding higher up in the gastrointestinal tract, such as from a peptic ulcer. Green, soft stools (Choice D) are more indicative of rapid transit through the intestines, possibly due to dietary factors or infections such as gastroenteritis.
Question 2 of 5
The health care provider is treating a child with meningitis with a course of antibiotic therapy. When should the nurse expect the child to be out of isolation?
Correct Answer: C
Rationale: The correct answer is C because a child with bacterial meningitis should be isolated for at least 24 hours until antibiotic therapy has been initiated. This period allows the antibiotics to start working against the infection, reducing the risk of spreading it to others. Choice A is incorrect because isolation is not solely based on completing the course of antibiotics; the initiation is crucial. Choice B is incorrect as waiting for a negative CNS culture may take longer and delay necessary precautions. Choice D is incorrect as symptom resolution does not guarantee the eradication of the infection and may still pose a risk of transmission.
Question 3 of 5
An infant has been diagnosed with cradle cap. What is the correct intervention to treat the scalp?
Correct Answer: B
Rationale: Cradle cap is a common condition in infants characterized by crusty patches on the scalp. The correct intervention to treat cradle cap is to apply mineral oil. Mineral oil helps soften the crusty patches, making it easier to remove them gently. Alcohol (Choice A) can be too harsh for an infant's sensitive skin and may cause irritation. Calamine (Choice C) is used to relieve itching associated with conditions like chickenpox or insect bites, not for treating cradle cap. A&D ointment (Choice D) is typically used for diaper rash and minor skin irritations, not for cradle cap.
Question 4 of 5
A child has developed a diaper rash, and the parents are using zinc oxide to treat it. What does the nurse suggest to aid in the removal of the zinc oxide?
Correct Answer: C
Rationale: To completely remove ointment, especially zinc oxide, mineral oil should be used. Mineral oil helps in gently breaking down and lifting the ointment without causing irritation. Mild soap and water (Choice A) may not be effective in completely removing zinc oxide. A cotton ball (Choice B) may not provide the necessary lubrication to aid in the removal process. Alcohol swabs (Choice D) can be harsh on the skin and are not recommended for this purpose.
Question 5 of 5
The cognitive impairment is classified into four levels based on the intelligence quotient (IQ). How is a child with an IQ of 45 classified?
Correct Answer: C
Rationale: A child with an IQ of 45 is classified as 'Trainable' in the context of cognitive impairment levels. This category is determined by an IQ range of 35 to 55. Choice A ('Within the normal low range') is incorrect as an IQ of 45 falls within the range associated with the 'Trainable' level, not the 'Normal low range.' Choice B ('Educable') is incorrect because this classification typically corresponds to individuals with slightly higher IQs that allow for academic progress with support. Choice D ('Severe') is incorrect as it does not align with the IQ level of 45, which falls within the 'Trainable' category.
