What is the recommended drink for athletes during practice and competition?
- A. Sports drinks to replace carbohydrates
- B. Cold water for gastrointestinal tract rapid absorption
- C. Carbonated beverages to help with acid-base balance
- D. Enhanced performance carbohydrate-electrolyte drinks
Correct Answer: B
Rationale: Cold water, consumed 4-8 oz every 15-20 minutes, promotes rapid gastric and intestinal absorption for hydration. Sports drinks may cause gastrointestinal upset, carbonated beverages are discouraged, and enhanced drinks lack evidence of performance benefits.

What measure is important in managing hypercalcemia in a child who is immobilized?
- A. Provide adequate hydration.
- B. Change position frequently.
- C. Encourage a diet high in calcium.
- D. Provide a diet high in calories for healing.
Correct Answer: A
Rationale: Vigorous hydration (3000-4000 ml/day for adolescents) with diuretics helps manage hypercalcemia by promoting calcium excretion. Frequent position changes address skin and respiratory issues, calcium intake is restricted, and high-protein, not just high-calorie, diets aid healing.
A student athlete was injured during a basketball game. The nurse observes significant swelling. The player states he thought he heard a pop, that the pain is pretty bad, and that the ankle feels as if it is coming apart. Based on this description, the nurse suspects what injury?
- A. Sprain
- B. Fracture
- C. Dislocation
- D. Stress fracture
Correct Answer: A
Rationale: A sprain, common in ankle injuries, involves ligament stretching or tearing, often with a pop sound, severe pain, and joint instability. Fractures involve bone, dislocations disrupt joint alignment, and stress fractures result from repetitive stress, not acute trauma with a pop.
Immobilization causes what effect on metabolism?
- A. Hypocalcemia
- B. Decreased metabolic rate
- C. Positive nitrogen balance
- D. Increased levels of stress hormones
Correct Answer: B
Rationale: Immobilization reduces metabolic rate, slowing systems and food intake. It causes hypercalcemia, negative nitrogen balance from muscle atrophy, and decreased stress hormone production due to reduced coping capacity.
What condition can result from the bone demineralization associated with immobility?
- A. Osteoporosis
- B. Pooling of blood
- C. Urinary retention
- D. Susceptibility to infection
Correct Answer: A
Rationale: Bone demineralization from immobility leads to osteoporosis, increasing fracture and renal calculi risk. Blood pooling, urinary retention, and infection susceptibility are other immobilization effects but not directly caused by bone demineralization.
A 14-year-old is admitted to the emergency department with a fracture of the right humerus epiphyseal plate through the joint surface. What information does the nurse know regarding this type of fracture?
- A. It will create difficulty because the child is left handed.
- B. It will heal slowly because this is the weakest part of the bone.
- C. This type of fracture requires different management to prevent bone growth complications.
- D. This type of fracture necessitates complete immobilization of the shoulder for 4 to 6 weeks.
Correct Answer: C
Rationale: A Salter type III fracture through the epiphyseal plate requires specific management, often surgical, to prevent growth complications like angular deformities. Hand dominance is irrelevant, healing is rapid at the growth plate, and complete immobilization isn?t always needed.
