Correct Answer: C

Rationale: In the management of acute asthma exacerbations, the first-line medication for quick relief of bronchoconstriction is a short-acting beta agonist, such as albuterol. These medications help to rapidly open up the airways, providing immediate relief to the patient. Inhaled corticosteroids are more commonly used for long-term control of asthma symptoms, while oral corticosteroids and leukotriene receptor antagonists are often reserved for more severe or chronic cases. Therefore, in a child experiencing severe asthma symptoms, the practical nurse should anticipate the administration of short-acting beta agonists as the initial intervention to provide quick relief and improve breathing.

Correct Answer: A

Rationale: In a pediatric patient with severe dehydration and signs of compromised hemodynamics such as tachycardia (heart rate of 150 bpm) and hypotension (blood pressure of 90/50 mm Hg), the priority intervention is to administer IV fluids as prescribed. Immediate fluid resuscitation is essential to restore hydration, improve perfusion, and stabilize the child's vital signs. While it's important to monitor urine output, initiating fluid resuscitation takes precedence in this situation. Notifying the healthcare provider can cause a delay in critical intervention, and waiting to reassess vital signs in 30 minutes can be detrimental in a child with severe dehydration and compromised hemodynamics.

Correct Answer: C

Rationale: The correct answer is C because providing a developmentally safe environment for a 6-month-old infant is crucial as they begin to explore their surroundings more actively. This includes ensuring that the environment is free of hazards and that the infant is supervised to prevent accidents. Choice A is incorrect because self-feeding finger foods may not be developmentally appropriate for a 6-month-old infant. Choice B is incorrect as most infants are able to sit up with support around 6 months of age without the need for specific teaching strategies. Choice D is also incorrect as while appetite changes can occur, explaining a specific increase in appetite over the next 6 months is not a primary focus when discussing developmental changes with parents of a 6-month-old.

Correct Answer: D

Rationale: When a child presents with fever, sore throat, swollen red spots, and fluid-filled blisters, it may indicate a contagious viral infection. In such cases, implementing transmission precautions is crucial to prevent the spread of the infection to others in the pediatric clinic or community. Obtaining a fluid culture from the blisters (Choice A) may not be necessary at the initial stage without knowing the cause of the infection. Administering a fever-reducing medication (Choice B) may help manage symptoms but doesn't address the need for preventing transmission. Covering the drainage vesicles with a dressing (Choice C) may provide comfort to the child but does not directly address the risk of transmission to others.

Correct Answer: C

Rationale: The correct answer is to reassure the parents that some children walk later than others. It is essential to understand that children reach developmental milestones at different ages. Walking independently can occur later in some children, and it is normal. Referring the child for a developmental assessment (Choice A) may cause unnecessary concern at this stage. Encouraging physical therapy (Choice B) or discussing early intervention services (Choice D) may not be warranted unless there are specific concerns identified during the checkup.
