Correct Answer is []
Explanation
Condition:
Pyelonephritis: The presence of fever, frequent and painful urination, and costovertebral angle tenderness, along with the urinalysis findings (cloudy urine, leukocyte esterase, nitrites, WBCs) and elevated WBC count suggest an upper urinary tract infection, likely pyelonephritis.
Actions to Take:
Request prescription for antibiotics: Pyelonephritis is a bacterial infection that requires antibiotic treatment to prevent complications and resolve the infection.
Encourage increased fluid intake: This helps to flush bacteria from the urinary tract, reducing the concentration of bacteria in the urine and helping to relieve symptoms.
Parameters to Monitor:
Child’s report of urgency: This can help assess if the infection is affecting the lower urinary tract as well and track the effectiveness of treatment.
Urine odor: Foul-smelling urine can indicate ongoing infection or bacterial presence and can be an indicator of the effectiveness of the treatment.
Correct Answer is D
Explanation
A. Bedrest is not specifically required for children with varicella; activity should be based on the child's energy levels and comfort.
B. Bathing can be done carefully even with crusted lesions. Good hygiene can help prevent secondary infections.
C. If the guardian has had chickenpox, they are usually immune and do not need to wear a mask. The concern is more for immunocompromised individuals.
D. The child is no longer contagious once all the lesions have crusted over, making it safe to take them to the playroom.
