The nurse is assessing a child with croup and a sore throat in the ED. The child is drooling and agitated. The nurse should know that examining the child's throat using a tongue depressor might precipitate which of the following?

Correct Answer: C

Rationale: When assessing a child with croup who is drooling and agitated, the nurse should be aware that examining the throat using a tongue depressor can potentially precipitate a complete airway obstruction. Croup is characterized by upper airway inflammation, particularly around the larynx and trachea, leading to a barking cough, hoarseness, and respiratory distress. In a child with croup who is already showing signs of airway compromise such as drooling and agitation, any manipulation in the throat area can cause further swelling and lead to a complete obstruction of the airway. This can be a life-threatening emergency requiring immediate intervention to secure the airway and ensure adequate oxygenation. Therefore, utmost caution should be taken when performing any procedures that may exacerbate the child's respiratory distress in this situation.

Correct Answer: D

Rationale: The correct information that the nurse should include in the teaching is that clothing should always fit loosely over the harness. This is important to prevent restriction of movement and ensure comfort for the child wearing the Pavlik harness. Tight clothing can cause discomfort, skin irritation, and interfere with the effectiveness of the harness in positioning the hip properly. Parents should be advised to choose clothing that is loose-fitting and does not put pressure on the harness or the child's skin.

Correct Answer: B

Rationale: Hemophilia is an X-linked recessive genetic disorder, meaning it is carried on the X chromosome. Females have two X chromosomes, while males have one X and one Y chromosome. In this scenario, the female carrier has one X chromosome with the hemophilia gene and one normal X chromosome. When she has children, she has a 50% chance of passing on the X chromosome with the hemophilia gene to her sons. Therefore, half the male children will inherit hemophilia, while half will not. Daughters, on the other hand, have a 50% chance of inheriting the X chromosome with the hemophilia gene but since it is a recessive disorder, they will be carriers of hemophilia rather than having the disease itself.

Correct Answer: A

Rationale: Corticosteroids are not typically used in the treatment of heart insufficiency. The mainstay of treatment for heart insufficiency includes medications like oxygen, digoxin, diuretics, and sometimes blood transfusions of packed red blood cells. Corticosteroids are more commonly used to reduce inflammation and immune responses in conditions like asthma, arthritis, and certain autoimmune diseases.
