Nursing Elites

1. Congenital heart defects have traditionally been divided into acyanotic or cyanotic defects. Based on the nurse’s knowledge of congenital heart defects, this system in clinical practice is

• A. helpful because it explains the hemodynamics involved
• B. helpful because children with cyanotic defects are easily identified
• C. problematic because cyanosis is rarely present in children
• D. problematic because children with acyanotic heart defects may develop cyanosis

Correct answer: D

Rationale: The classification system of congenital heart defects into acyanotic or cyanotic defects is problematic because children with acyanotic heart defects may develop cyanosis, complicating the differentiation. Cyanosis can occur in some acyanotic defects due to various reasons such as right-to-left shunting or decreased pulmonary blood flow, making the classification based solely on cyanosis misleading. Choice A is incorrect because while the classification may involve hemodynamics, the main issue lies in the potential for acyanotic defects to develop cyanosis. Choice B is incorrect as the ease of identifying children with cyanotic defects does not address the main problem with the classification system. Choice C is also incorrect as the presence of cyanosis is not the only factor determining the classification's validity.

2. The nurse is caring for a 10-year-old with Duchenne muscular dystrophy. As part of the plan of care, the nurse focuses on maintaining his cardiopulmonary function. Which intervention would the nurse implement to best promote maximum chest expansion?

• A. Deep-breathing exercises
• B. Upright positioning
• C. Coughing
• D. Chest percussion

Correct answer: B

Rationale: Upright positioning is the optimal intervention to promote maximum chest expansion in a child with Duchenne muscular dystrophy. By placing the child in an upright position, gravity can assist in expanding the chest cavity, facilitating better lung expansion and improving breathing efficiency. Deep-breathing exercises may be beneficial but are not as effective in maximizing chest expansion as upright positioning. Coughing and chest percussion focus more on airway clearance and are not directly aimed at promoting chest expansion.

3. 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.

4. A 4-year-old fell from a third-story window and landed on her head. She is semiconscious with slow, irregular breathing and bleeding from her mouth. After performing a jaw-thrust maneuver with simultaneous stabilization of her head, what should you do next?

• A. Suction the oropharynx
• B. Insert a nasopharyngeal airway
• C. Initiate positive pressure ventilations
• D. Administer oxygen via mask

Correct answer: A

Rationale: In this scenario, the patient is experiencing airway compromise due to the fall and potential oropharyngeal obstruction from bleeding. Performing a jaw-thrust maneuver with head stabilization helps maintain the airway patency. The next step should be to suction the oropharynx to clear any blood or secretions, which can obstruct the airway and lead to aspiration. Inserting a nasopharyngeal airway may worsen bleeding or cause further injury to the patient's airway. Initiating positive pressure ventilations can be ineffective if the airway is not cleared first. Administering oxygen via mask is not the immediate priority; ensuring a patent airway by suctioning takes precedence.

5. .A nurse is caring for an infant whose vomiting is intractable. For what complication is it most important for the nurse to assess?

• A. Acidosis
• B. Alkalosis
• C. Hyperkalemia
• D. Hypernatremia

Correct answer: B

Rationale: Intractable vomiting can lead to alkalosis due to loss of stomach acids.
