A boy who has fractured his forearm is unable to extend his fingers. The nurse knows that this
may indicate damage to the epiphyseal plate.
is normal following this type of injury.
may indicate compartment syndrome.
may indicate fat embolism.
The Correct Answer is C
Compartment syndrome is a condition that can occur following an injury, such as a fracture, where there is increased pressure within a closed space (compartment) in the body. In the case of a forearm fracture, swelling and increased pressure within the compartment can lead to compression of the nerves and blood vessels, resulting in symptoms such as pain, numbness, and decreased function of the affected muscles.
The inability to extend the fingers suggests impairment of the extensor muscles, which are innervated by the radial nerve. If the radial nerve is compressed or injured due to compartment syndrome, it can result in a loss of function in the muscles it innervates, leading to the inability to extend the fingers.
damage to the epiphyseal plate in (option A) is incorrect because it, is not related to the inability to extend the fingers. The epiphyseal plate is the growth plate in long bones, and damage to it would typically affect bone growth rather than finger extension.
, stating that it is normal following this type of injury in (option B), is incorrect. Inability to extend the fingers is not a normal or expected finding after a forearm fracture. It suggests a potential complication or underlying issue.
fat embolism in (option D) is incorrect because it, is unlikely to cause an inability to extend the fingers. Fat embolism occurs when fat globules from a broken bone enter the bloodstream and can lead to respiratory and neurological symptoms, but it would not specifically cause an isolated loss of finger extension.

Correct Answer is B
Explanation
The anatomy of the urinary tract can influence the susceptibility to urinary tract infections (UTIs). In the case of young girls, their urethra is shorter compared to adult females, which increases the likelihood of bacteria reaching the bladder. The shorter urethra provides a shorter distance for bacteria to travel from the outside of the body to the bladder, making it easier for bacteria to enter and cause an infection.
Prostatic secretions in males in (option A) is incorrect because they are not directly related to the increased susceptibility to UTIs. Prostatic secretions can, however, contribute to conditions like prostatitis, which is an inflammation of the prostate gland that can be associated with urinary symptoms and sometimes bacterial infections.
Frequent emptying of the bladder in (option C) is incorrect because it is generally considered a healthy practice as it helps to flush out any potential bacteria in the urinary tract. It does not predispose the urinary tract to infection.
Increased fluid intake in (option D) is incorrect because it is generally encouraged to maintain proper hydration and urinary tract health. It can help to flush out bacteria from the urinary system, reducing the risk of infection.
While these factors may have implications for urinary tract health, the specific factor that predisposes the urinary tract to infection, particularly in young girls, is the short urethra (B).
Correct Answer is C
Explanation
Hypoglycaemia is characterized by low blood sugar levels. In children, symptoms of hypoglycaemia can vary, but irritability is a common sign. Other signs and symptoms of hypoglycaemia in children may include sweating, trembling, pale skin, hunger, weakness, confusion, and dizziness.
Normal sensorium and serum glucose greater than 160 mg/dL in (Option A) is incorrect because a normal sensorium (normal level of consciousness) and a serum glucose level greater than 160 mg/dL would not be indicative of hypoglycaemia.
Urine positive for ketones and serum glucose greater than 300 mg/dL in (Option B) is incorrect because it describes characteristics of hyperglycaemia (high blood sugar levels) rather than hypoglycaemia. Positive urine ketones and a serum glucose level greater than 300 mg/dL are commonly seen in diabetic ketoacidosis, a complication of high blood sugar levels in diabetes.
Increased urination and serum glucose less than 120 mg/dL in (Option D) is incorrect because it describes increased urination and a serum glucose level less than 120 mg/dL. While a serum glucose level less than 120 mg/dL could indicate hypoglycaemia, increased urination is not a typical sign of hypoglycaemia. Increased urination may be seen in conditions such as diabetes mellitus when blood sugar levels are consistently high.
