When describing urticaria, what would an 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 where histamine release leads to vasodilation and the formation of characteristic wheals. Choice A is incorrect as urticaria is associated with type I hypersensitivity, not type IV. Choice C is incorrect because in urticaria, erythema typically appears before the development of wheals. Choice D is incorrect as urticaria is typically pruritic and does not blanch with pressure.

A nurse is providing care to a child with a diagnosis of bronchiolitis. What is the priority nursing intervention?
- A. Administering bronchodilators
- B. Providing respiratory therapy
- C. Monitoring oxygen saturation
- D. Encouraging fluid intake
Correct Answer: B
Rationale: The correct answer is providing respiratory therapy. In bronchiolitis, the priority is to maintain airway patency through interventions such as suctioning, positioning, and oxygen therapy. While bronchodilators may be used in some cases, they are not the initial priority. Monitoring oxygen saturation is important but comes after ensuring airway patency. Encouraging fluid intake is essential for hydration but is not the priority over maintaining a patent airway.
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.
The parents of a child who is scheduled for open-heart surgery ask why their child must be subjected to chest tubes after surgery. What should the nurse consider before responding in language the parents will understand?
- A. They will increase tidal volumes.
- B. Drainage of air and fluid will be facilitated.
- C. They will maintain positive intrapleural pressure.
- D. Pressure on the pericardium and chest wall will be regulated.
Correct Answer: B
Rationale: Chest tubes are necessary after open-heart surgery to facilitate the drainage of air and fluid from the chest cavity. These tubes help prevent complications such as pneumothorax (accumulation of air in the pleural space) or cardiac tamponade (build-up of fluid in the pericardial sac), which can be serious postoperative issues. Options A, C, and D are incorrect because chest tubes are primarily used for draining purposes and not for increasing tidal volumes, maintaining positive intrapleural pressure, or regulating pressure on the pericardium and chest wall.
When picked up by a parent or the nurse, an 8-month-old infant screams and seems to be in pain. After observing this behavior, what should the nurse discuss with the parent?
- A. Accidents and the importance of preventing them
- B. Limiting the infant's playtime with other children in the family
- C. Any other behaviors that the parent may have noticed
- D. Nutrition and specific vitamins recommended for infants
Correct Answer: C
Rationale: Discussing any other observed behaviors with the parent is important to identify patterns or potential issues that could be affecting the infant's well-being. By exploring additional behaviors, the nurse can gather more information to assess the infant comprehensively. This approach allows for a more holistic understanding of the infant's health status, rather than focusing solely on the observed behavior of screaming and apparent pain. Options A, B, and D are incorrect as they do not directly address the need to explore other behaviors that may provide insights into the infant's condition and well-being.
What type of play does a caregiver expect when observing a toddler in a playroom with other children?
- A. Parallel
- B. Solitary
- C. Cooperative
- D. Competitive
Correct Answer: A
Rationale: When observing a toddler in a playroom with other children, a caregiver would expect to witness parallel play. Parallel play is common among toddlers, where they play alongside but not directly with other children. This type of play is characterized by children engaging in similar activities near each other without interactive or cooperative play. Solitary play (Choice B) involves a child playing alone, while cooperative play (Choice C) involves children playing together towards a common goal. Competitive play (Choice D) involves activities where children compete against each other.
