A nurse in a pediatric clinic is reviewing the laboratory results of a school-age child. Which of the following findings indicates the child may have a potential bacterial infection?
Increased hemoglobin
Increased absolute neutrophils
Decreased C-reactive protein
Decreased platelets
The Correct Answer is B
Rationale:
A. Increased hemoglobin: Elevated hemoglobin levels are generally associated with dehydration, high altitude, or chronic hypoxia, but they are not specific indicators of infection. Hemoglobin does not provide direct evidence of a bacterial process.
B. Increased absolute neutrophils: Neutrophils are the primary white blood cells involved in fighting bacterial infections. An elevated absolute neutrophil count suggests an acute bacterial infection or an inflammatory response caused by bacterial pathogens.
C. Decreased C-reactive protein: CRP is a marker of inflammation, often elevated during bacterial infections. A decreased CRP level makes bacterial infection less likely and is not consistent with the inflammatory response usually seen in such cases.
D. Decreased platelets: Low platelet counts (thrombocytopenia) can result from viral infections, autoimmune diseases, or bone marrow disorders. While they may be altered in sepsis, they are not a reliable or primary marker of a typical bacterial infection.

Correct Answer is D
Explanation
Rationale:
A. Use a loud tone of voice when speaking with the client: Clients with visual impairments do not necessarily have hearing loss. Speaking loudly is unnecessary and may be perceived as disrespectful or startling. Clear, calm, and descriptive communication is more appropriate.
B. Rearrange client’s bedside table items frequently: Frequently moving personal items creates confusion and increases the risk of accidents or frustration for a visually impaired client. Consistent item placement enhances safety and independence.
C. Guide the client by walking parallel with them: Walking parallel without physical or verbal guidance may not be helpful. It’s more effective to offer the client your arm so they can follow your movement and safely navigate their surroundings.
D. Remove objects from client's path to the bathroom: Clearing obstacles from the client's walking path reduces the risk of tripping and falls. This is a key safety intervention for clients with reduced visual sensory perception and promotes independent, safe mobility.
Correct Answer is ["8"]
Explanation
Calculation:
Desired dose = 40 mg.
Available concentration = 5 mg/mL.
- Calculate the volume to administer.
Volume (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 40 mg / 5 mg/mL
= 8 mL.
