A nurse is caring for a 15-year-old adolescent. Exhibits Drag words from the choices below to fill in each blank in the following sentence. The nurse reviews the EMR and determines that the adolescent is at risk for developing which of the following complications? The adolescent is at risk for developing dropdown and dropdown.

Rationale for correct options: Anemia: The hemoglobin (11 g/dL) is below the stated reference range (12–18 g/dL) and hematocrit is at the low end (32%). Whether chronic or acute, this low Hgb reduces the blood’s oxygen-carrying capacity. In the setting of pneumonia (impaired gas exchange, increased work of breathing, fever), reduced oxygen delivery from anemia increases the risk of tissue hypoxia, worsened dyspnea, tachycardia (compensatory), and clinical deterioration even if the pulse oximeter reads near-normal saturation. Dehydration: The adolescent has not eaten in 2 days and has a fever and tachypnea, both increase insensible fluid losses and reduce intake. An elevated BUN (22 mg/dL) and hypernatremia (Na 148 mEq/L) are classic biochemical markers of volume depletion / free-water deficit. Relative hypotension and tachycardia are consistent with decreased intravascular volume/compensated hypovolemia. Rationale for Incorrect options: Pleural effusion: Parapneumonic effusion is a known complication of pneumonia; however, the chest x-ray here is described as showing small infiltrates with minimal lobar consolidation and no mention of effusion. There are also no exam findings documented (e.g., dullness to percussion, markedly decreased breath sounds) to suggest effusion at this time. Muscle cramps: Muscle cramps are most commonly associated with electrolyte disturbances (notably hypokalemia, hypocalcemia) or severe dehydration with specific electrolyte shifts. In this case, potassium is normal (4.1 mEq/L) and the primary electrolyte abnormality is hypernatremia, which more commonly causes neurologic signs than isolated cramps.
