Correct Answer: A

Rationale: In a child with acute glomerulonephritis, hypertension is the most concerning assessment finding as it can indicate worsening renal function. Hypertension is a common complication of glomerulonephritis and can lead to further kidney damage if not managed promptly. Monitoring and controlling blood pressure is crucial in these cases to prevent complications and preserve renal function. Gross hematuria, proteinuria, and periorbital edema are also common findings in acute glomerulonephritis but hypertension poses a higher risk for renal damage if left uncontrolled.

Correct Answer: B

Rationale: Teaching children how to swim is valuable, but parental supervision around water is essential to prevent drowning. It's crucial to emphasize constant supervision when young children are near water, regardless of their swimming abilities. The other choices (A, C, and D) demonstrate appropriate safety measures for injury prevention in toddlers, such as securing cleaning supplies, ensuring helmet use during tricycle rides, and using a car seat for every car ride.

Correct Answer: B

Rationale: The correct answer is B: 'Decreased heart rate.' Propranolol is a beta-blocker commonly used to manage symptoms of hyperthyroidism, including tachycardia. Monitoring for a decreased heart rate is important as it indicates the drug's therapeutic response in controlling the elevated heart rate associated with Graves' disease. Choices A, C, and D are incorrect because weight gain, reduced headaches, and diminished fatigue are not typical therapeutic responses to propranolol in the context of managing Graves' disease.

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.

Correct Answer: B

Rationale: When screening a 5-year-old for strabismus, directing the child through the six cardinal positions of gaze is the most appropriate action. This method helps the nurse to assess eye alignment, which is crucial in identifying any misalignment that may indicate strabismus. Choices A, C, and D are incorrect. Having the child identify colored patterns on polychromatic cards is more related to visual acuity testing rather than strabismus screening. Inspecting the child for the setting sun sign is not a standard method for strabismus screening. Observing the child for blank, sunken eyes is not specific to strabismus assessment.
