An 11-year-old patient complains of pain after pitching during a baseball game. On examination, the NP notes increased pain in the right elbow with wrist flexion against resistance. This finding is most consistent with:
lateral epicondylitis.
medial epicondylitis.
ulnar collateral ligament injury.
arthritis in the elbow.
The Correct Answer is B
Rationale:
A. Lateral epicondylitis, or “tennis elbow,” causes pain on the lateral (outside) aspect of the elbow, typically worsened with wrist extension against resistance.
B. Medial epicondylitis, or “little league elbow,” causes pain on the medial (inside) aspect of the elbow, which is aggravated by wrist flexion against resistance. This is common in young athletes who perform repetitive throwing motions, such as baseball pitchers.
C. Ulnar collateral ligament injury involves instability of the elbow and pain with valgus stress, rather than isolated pain with wrist flexion.
D. Arthritis in the elbow is uncommon in an 11-year-old and typically presents with chronic pain, swelling, and decreased range of motion, not acute pain following pitching.

Correct Answer is B
Explanation
Rationale:
A. A throat culture identifies current streptococcal infection but does not confirm a recent infection that may have triggered glomerulonephritis.
B. An antistreptolysin O (ASO) titer measures antibodies produced in response to a recent group A Streptococcus infection, making it the most reliable test for linking acute glomerulonephritis to a prior streptococcal infection.
C. Erythrocyte sedimentation rate (ESR) is a nonspecific marker of inflammation and cannot confirm recent streptococcal infection.
D. Blood urea nitrogen (BUN), creatinine, and glomerular filtration rate (GFR) assess kidney function but do not indicate the causative pathogen.
Correct Answer is B
Explanation
Rationale:
A. 0.1–0.2 u/kg/day is too low for initial insulin requirements in children with type 1 diabetes.
B. 0.25–0.45 units/kg/day is the recommended starting total daily insulin dose for children younger than 12 years. This total is typically divided into basal and bolus doses to achieve glycemic control while minimizing the risk of hypoglycemia.
C. 0.3–1.0 u/kg/day may be used in older children or adolescents, especially during puberty when insulin resistance increases.
D. 1–1.5 u/kg/day is generally too high for initial dosing and may increase the risk of hypoglycemia in younger children.
