An instructor is developing a plan for a class of nursing students on various skin disorders. When describing urticaria, what would the instructor include?
- A. It is a type IV hypersensitivity reaction.
- B. Histamine release leads to vasodilation.
- C. Wheals appear first followed by erythema.
- D. The nonpruritic rash blanches with pressure.
Correct Answer: B
Rationale: The correct answer is B. Urticaria is a type I hypersensitivity reaction, not type IV. When triggered, histamine release leads to vasodilation, causing characteristic wheals. Wheals are typically followed by erythema. The rash in urticaria is pruritic and does blanch with pressure, unlike the nonpruritic rash described in choice D. Therefore, the most appropriate description of urticaria includes histamine release and vasodilation, as stated in choice B.

What behavior does a toddler subjected to prolonged hospitalization with limited parental visits typically exhibit?
- A. Cheerful interactions with staff members
- B. Indications of sadness throughout the day
- C. Excessive crying when parents are not present
- D. Limited emotional response to the environment
Correct Answer: D
Rationale: Toddlers subjected to prolonged hospitalization with limited parental visits often exhibit a limited emotional response to the environment. This behavior is a common coping mechanism in young children facing such situations. While cheerful interactions with staff members (choice A) may occur occasionally, the overall response tends to be subdued. Indications of sadness throughout the day (choice B) and excessive crying when parents are not present (choice C) are less typical in this scenario, as the child may have learned to suppress emotions due to the challenging circumstances.
A child sitting on a chair in a playroom starts to have a tonic-clonic seizure with a clenched jaw. What is the nurse's best initial action?
- A. Attempt to open the jaw.
- B. Place the child on the floor.
- C. Call out for assistance from staff.
- D. Place a pillow under the child's head.
Correct Answer: B
Rationale: The correct initial action during a tonic-clonic seizure is to place the child on the floor to prevent injury. This action helps protect the child from falling off the chair and provides a safer environment for the seizure to occur. Attempting to open the jaw can cause harm or injury. Calling out for assistance is important but should follow the immediate action of moving the child to the floor. Placing a pillow under the child's head is not recommended as it may lead to airway obstruction or further injury during the seizure.
A child sitting on a chair in a playroom starts to have a tonic-clonic seizure with a clenched jaw. What is the nurse's best initial action?
- A. Attempt to open the jaw.
- B. Place the child on the floor.
- C. Call out for assistance from staff.
- D. Place a pillow under the child's head.
Correct Answer: B
Rationale: The best initial action during a tonic-clonic seizure is to place the child on the floor. This action helps prevent injury by providing a safe environment and allows for better management of the seizure episode. Attempting to open the jaw is not recommended as it may cause harm to the child or the nurse. Calling out for assistance is important but should not delay ensuring the child's safety first. Placing a pillow under the child's head is not advisable during a seizure as it can pose a risk of suffocation or choking.
Which cardiac defects are associated with tetralogy of Fallot?
- A. Right ventricular hypertrophy, atrial and ventricular defects, and mitral valve stenosis
- B. Origin of the aorta from the right ventricle and of the pulmonary artery from the left ventricle
- C. Right ventricular hypertrophy, ventricular septal defect, pulmonic stenosis, and overriding aorta
- D. Altered connection between the pulmonary artery and the aorta, right ventricular hypertrophy, and an atrial septal defect
Correct Answer: C
Rationale: The correct answer is C: Right ventricular hypertrophy, ventricular septal defect, pulmonic stenosis, and overriding aorta are the cardiac defects associated with Tetralogy of Fallot. In Tetralogy of Fallot, these specific abnormalities contribute to the classic features of the condition. Choice A is incorrect as it includes mitral valve stenosis, which is not typically part of Tetralogy of Fallot. Choice B describes transposition of the great arteries, not Tetralogy of Fallot. Choice D mentions an altered connection between the pulmonary artery and the aorta, which is not a defining characteristic of Tetralogy of Fallot.
A 6-year-old child with a diagnosis of juvenile idiopathic arthritis (JIA) is being discharged. What should the nurse include in the discharge teaching?
- A. Encourage participation in physical activity
- B. Provide a high-calorie diet
- C. Provide a low-sodium diet
- D. Administer intravenous fluids
Correct Answer: A
Rationale: Encouraging regular physical activity is essential in managing symptoms and improving joint function in juvenile idiopathic arthritis. Physical activity helps maintain joint mobility, muscle strength, and overall function. Providing a high-calorie diet may not be necessary unless there are specific concerns about the child's nutritional status. A low-sodium diet is not typically a priority in the management of JIA unless the child has comorbid conditions requiring sodium restriction. Administering intravenous fluids is not a standard discharge teaching for JIA unless there are specific medical indications necessitating it.
