Correct Answer: A

Rationale: The child's refusal to walk, along with swelling of the lower leg, indicates a possible fracture, specifically of the tibia. Fractures can cause pain and swelling, leading to difficulty or refusal to bear weight on the affected limb. Choice B, bruising of the gastrocnemius muscle, would not typically result in the child refusing to walk. Choice C, a possible fracture of the radius, is less likely given the location of the swelling and the associated refusal to walk. Choice D, stating no anatomic injury and attributing the child's behavior to wanting to be carried by the mother, is incorrect as the physical findings suggest a potential fracture that needs to be evaluated further.

Correct Answer: D

Rationale: The low oncotic pressure caused by hypoalbuminemia is a major pathophysiologic factor in the development of edema. In this case, monitoring the albumin level is crucial to assess the patient's fluid balance and potential for edema. While hemoglobin, temperature, and activity level are important parameters to monitor in a patient's assessment, they are not directly associated with the patient's current symptoms of toxic hepatitis and edema development. Therefore, the correct choice is the albumin level.

Correct Answer: C

Rationale: The correct answer is to take pancrelipase (Viokase) with each meal. Pancrelipase is a pancreatic enzyme replacement medication that helps with the digestion of nutrients. Patients with chronic pancreatitis often have difficulty digesting food properly due to insufficient pancreatic enzyme production. Taking pancrelipase with each meal assists in the breakdown of fats, proteins, and carbohydrates consumed during the meal. Option A ('at bedtime') is incorrect because enzymes should be taken with meals to aid in digestion. Option B ('in the morning') is not ideal as it does not ensure optimal enzyme activity during meals. Option D ('for abdominal pain') is incorrect as pancrelipase is not meant to be taken solely for pain relief but rather to aid in digestion.

Correct Answer: B

Rationale: The change from low-pitched wheezes to high-pitched wheezes indicates a shift from larger to smaller airway obstruction, suggesting increased narrowing of the airways. This change signifies a progression or worsening of the airway obstruction. The absence of evidence of secretions does not support the need for suctioning. Hyperventilation is characterized by rapid and deep breathing, which is not indicated by the information provided in the question.

Correct Answer: D

Rationale: A client diagnosed with active tuberculosis should be placed in isolation in a negative-pressure room to prevent transmission of infection to others. Placing the client in a negative-pressure room ensures that air is exhausted to the outside and received from surrounding areas, preventing tuberculin particles from traveling through the ventilation system and infecting others. Initiating standard precautions, as mentioned in choice C, is essential for infection control but is not specific to preventing transmission in the case of tuberculosis. Beginning drug therapy within 72 hours of diagnosis, as in choice A, is crucial for the treatment of tuberculosis but does not directly address preventing transmission. Placing the client in a positive-pressure room, as in choice B, is incorrect as positive-pressure rooms are used for clients with compromised immune systems to prevent outside pathogens from entering the room, which is not suitable for a client with active tuberculosis.
