Correct Answer: C

Rationale: To infuse 100 mL in 45 minutes, the infusion rate should be set to 133 mL/hour (100 mL / 0.75 hours). This calculation is obtained by dividing the total volume to be infused by the total time for infusion (100 mL / 0.75 hours = 133 mL/hour). Therefore, choice C is the correct answer. Choices A, B, and D are incorrect because they do not accurately calculate the infusion rate required to deliver the medication within the specified time frame.

Correct Answer: B

Rationale: The correct answer is B: Pain for 3 consecutive months. Recurrent abdominal pain (RAP) is characterized by abdominal pain that occurs at least once per week for at least 2 months before diagnosis. Choosing option A is incorrect since morning headaches are not a common characteristic of RAP. Option C is incorrect because febrile episodes in the late afternoon are not typically associated with RAP. Option D is incorrect as diaphoresis (excessive sweating) when attacks occur is not a common finding in RAP.

Correct Answer: D

Rationale: The correct answer is D. In hypertrophic pyloric stenosis, a key assessment finding is an olive-shaped mass in the right upper quadrant of the abdomen, to the right of the midline. This mass is palpable and represents the hypertrophied pyloric muscle. Choices A, B, and C are incorrect because although they may be present in infants with feeding problems, the definitive assessment for hypertrophic pyloric stenosis is the presence of an olive-shaped mass on the right side of the abdomen, not a history of diarrhea, gastric pain, or poor appetite.

Correct Answer: A

Rationale: A yellow triage tag should be placed on the client with partial-thickness burns covering 10% of his lower body. Yellow tags indicate delayed treatment, suitable for serious injuries that are not immediately life-threatening. Black tags are used for deceased individuals, red tags for immediate treatment of life-threatening injuries, and green tags for minor injuries.

Correct Answer: B

Rationale: The correct answer is B. The gestational age at birth most influences the severity of respiratory distress syndrome (RDS). RDS is caused by a deficiency of surfactant and it occurs almost exclusively in preterm, low-birth weight infants. Therefore, the gestational age at birth is a key factor in determining the likelihood and severity of RDS. Choices A, C, and D are incorrect as they do not directly relate to the primary factor influencing the severity of RDS.
