Correct Answer: B

Rationale: The correct approach for an alert 4-year-old child with a mild airway obstruction, respiratory distress, a strong cough, and normal skin color is to provide oxygen, avoid agitation, and arrange for transport. Oxygen helps support breathing, avoiding agitation prevents worsening of the obstruction, and transport ensures the child receives further medical evaluation and treatment. Choices A, C, and D involve techniques that are not recommended for a mild airway obstruction in this scenario. Back blows, abdominal thrusts, chest thrusts, and finger sweeps are interventions used for different situations and not suitable for a child with the described symptoms.

Correct Answer: C

Rationale: The correct supportive measure for the school nurse to use for a boy with hemophilia who fell on his arm during recess is to elevate the area above the level of the heart. Elevating the affected area helps reduce bleeding and swelling in a child with hemophilia until factor replacement therapy can be provided. Applying warm, moist compresses (Choice A) may worsen bleeding by dilating blood vessels. Applying pressure for at least 1 minute (Choice B) is not recommended for hemophilia as it can lead to increased bleeding. Beginning passive range-of-motion (Choice D) should be avoided as it can exacerbate bleeding and further injury in a child with hemophilia.

Correct Answer: B

Rationale: The correct answer is to use a soft toothbrush for oral care. Children with hemophilia have a decreased ability to form blood clots, leading to prolonged bleeding. Using a soft toothbrush helps prevent trauma to the gums and oral mucosa, reducing the risk of bleeding. Encouraging participation in contact sports (Choice A) is contraindicated in hemophiliac patients due to the high risk of injury and bleeding. Administering nonsteroidal anti-inflammatory drugs (Choice C) and aspirin (Choice D) should be avoided in hemophilia as they can further increase the risk of bleeding due to their antiplatelet effects.

Correct Answer: C

Rationale: Keeping the newborn warm is crucial immediately after clearing the airway to prevent hypothermia, which can lead to complications in newborns. Administering free-flow oxygen is not necessary if the newborn is not in distress. Clamping and cutting the cord can be done after ensuring the newborn's warmth. Obtaining an APGAR score is important but can be done after ensuring the newborn is kept warm and stable.

Correct Answer: B

Rationale: The priority intervention for a 3-month-old infant hospitalized with respiratory syncytial virus (RSV) is to cluster care to conserve energy. Infants with RSV often have difficulty breathing and need to rest frequently. Clustering care involves grouping nursing interventions to allow for longer periods of rest between activities, which helps prevent exhaustion and conserve the infant's energy. Administering an antiviral agent is not the primary intervention for RSV, as it is a viral infection and antiviral agents are not typically used for RSV. Offering oral fluids is important for hydration but may not be the priority when the infant is struggling to breathe. Providing an antitussive agent should be done judiciously and under medical guidance, as suppressing the cough reflex can be detrimental in RSV cases where coughing helps clear airway secretions.
