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 B
Explanation
Rationale:
A. Disconnecting the catheter from the drainage bag to empty the bag: This increases the risk of introducing pathogens into the closed urinary drainage system, leading to potential catheter-associated urinary tract infections (CAUTIs). The drainage bag should be emptied without breaking the system.
B. Emptying the drainage bag when it is half full: This prevents backflow of urine, which could lead to infection or increased bladder pressure. Regular emptying also allows for accurate measurement of urine output and maintains client comfort.
C. Keeping the drainage bag above waist level: Elevating the bag above the bladder increases the risk of backflow of urine into the bladder, which can introduce bacteria and cause infection. The bag should always remain below the level of the bladder.
D. Using sterile gloves when emptying the drainage bag: Sterile gloves are not necessary for this procedure. Clean gloves are sufficient since the nurse or AP is not entering the sterile parts of the urinary system but rather emptying the bag from the outlet port.
Correct Answer is B
Explanation
Rationale:
A. Administer a dose of atomoxetine to decrease anxiety: Atomoxetine is a non-stimulant medication used primarily for ADHD, not for acute anxiety or panic attacks. It is not effective for treating panic symptoms and is not appropriate in this situation.
B. Sit with the client to provide a sense of security: Remaining with the client during a panic attack helps reduce fear, provides emotional support, and ensures safety. Calm presence and reassurance are essential to help the client regain a sense of control.
C. Encourage the client to watch television: Watching television requires attention and focus, which may be impaired during a panic attack. This suggestion does not address the immediate need for safety, calm, and emotional support.
D. Teach the client how to meditate: Teaching new coping techniques during a panic attack may be ineffective, as the client is overwhelmed and unable to concentrate. Such strategies are better introduced when the client is calm and receptive.
