When reviewing the complete blood cell count report for a child suspected of having a viral infection, the suspicion increases with elevated:
neutrophils.
lymphocytes.
eosinophils.
basophils.
The Correct Answer is B
Rationale:
A. Neutrophils are typically elevated in bacterial infections, not viral infections.
B. Lymphocytes often increase in response to viral infections, so an elevated lymphocyte count supports the suspicion of a viral etiology.
C. Eosinophils are primarily associated with allergic reactions and parasitic infections.
D. Basophils are involved in inflammatory and allergic responses but are not a primary indicator of viral infection.

Correct Answer is B
Explanation
Rationale:
A. Metabolic acidosis may cause rapid breathing or lethargy but is not primarily indicated by fever.
B. In infants younger than 3 months, a temperature greater than 100.4°F (38°C) is concerning for a serious bacterial or viral infection due to their immature immune systems. Even mild fevers in this age group warrant prompt evaluation for sepsis, urinary tract infections, or meningitis.
C. Renal artery disease does not typically present with isolated fever in young infants.
D. Congenital heart defects may cause cyanosis, tachypnea, or poor feeding, but fever is not a primary sign.
Correct Answer is B
Explanation
Rationale:
A. Sulfamethoxazole is not the treatment of choice for Giardia lamblia infections.
B. Metronidazole is the first-line treatment for giardiasis in children. It is effective in eradicating the protozoal infection, alleviating symptoms such as diarrhea, abdominal pain, and nausea, and preventing transmission. Pediatric dosing should be weight-based, typically for 5–7 days.
C. Fluconazole (Diflucan) is an antifungal agent and not effective against protozoal infections like giardiasis.
D. Erythromycin/sulfisoxazole acetyl (Pediazole) is an antibiotic combination used for bacterial infections, not protozoal infections.
