Correct Answer: A

Rationale: Nausea and vomiting are more common in children following head trauma due to their higher risk of increased intracranial pressure. Children have less skull compliance and higher brain water content, making them more susceptible to developing symptoms like nausea and vomiting. Altered mental status (choice B) can occur in both children and adults but is not more common in children. Tachycardia and diaphoresis (choice C) are nonspecific and can occur in both age groups. Changes in pupillary reaction (choice D) are not typically more common in children following head trauma compared to adults.

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: B

Rationale: The correct answer is B: 'Warmth at skin disruption site.' Cellulitis is characterized by localized warmth at the site of skin disruption, which indicates an infection. Choice A, 'Red, raised hair follicles,' is more typical of folliculitis. Choice C, 'Papules progressing to vesicles,' is suggestive of conditions like herpes simplex virus infections. Choice D, 'Honey-colored exudate,' is associated with impetigo, not cellulitis. When assessing cellulitis, nurses should primarily look for warmth, erythema, edema, and tenderness at the affected site.

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: 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.
