A nurse is caring for a toddler who has acute laryngotracheobronchitis and has been placed in a cool mist tent. Which of the following findings indicates that the treatment has been effective?

Choice A: Muscular dystrophy is not an example of a neural tube defect, but rather a group of genetic disorders that cause progressive weakness and loss of muscle mass. Muscular dystrophy affects the skeletal muscles that control movement and may also affect the heart, lungs, or other organs. Muscular dystrophy is caused by mutations in genes that encode proteins that protect muscle fibers from damage.

Choice B: Spina bifida is an example of a neural tube defect, which is a birth defect that occurs when the neural tube, which is the structure that develops into the brain and spinal cord, does not close completely during the first month of pregnancy. Spina bifida causes an opening in the spine that exposes the spinal cord and nerves and may result in physical and mental disabilities. Spina bifida can be prevented by taking folic acid before and during pregnancy.

Choice C: Hydrocephalus is not an example of a neural tube defect, but rather a condition that causes accumulation of cerebrospinal fluid (CSF) in the brain. Hydrocephalus can increase the pressure inside the skull and damage the brain tissue and function. Hydrocephalus can be caused by congenital defects, infections, injuries, tumors, or bleeding in the brain.

Choice D: Cerebral palsy is not an example of a neural tube defect, but rather a group of disorders that affect movement, balance, and posture. Cerebral palsy is caused by damage to the developing brain before, during, or after birth. Cerebral palsy can affect muscle tone, coordination, reflexes, or speech. Cerebral palsy can be caused by infections, injuries, lack of oxygen, or genetic mutations.

Choice A: Urinary incontinence is a condition of involuntary loss of urine control, which can be caused by various factors, such as nerve damage, bladder dysfunction, or medication side effects. It is not always caused by neuroblastoma, which is a type of cancer that arises from immature nerve cells.

Choice B: Blood-fed is not a term that describes a neuroblastoma. Neuroblastoma is a type of cancer that arises from immature nerve cells, which can form tumors in various parts of the body, such as the adrenal glands, abdomen, chest, or spine.

Choice C: Tiny is not a term that describes a neuroblastoma. Neuroblastoma can vary in size and shape depending on the location and stage of the tumor. Some neuroblastomas can be very large and cause compression of nearby organs or structures.

Choice D: Unfortunately, much of the time, by the time a diagnosis has been made, metastasis has already occurred. This statement describes a neuroblastoma accurately. Neuroblastoma is a type of cancer that arises from immature nerve cells, which can spread rapidly to other parts of the body, such as the bones, liver, lymph nodes, or skin.
Metastasis is the process of cancer cells breaking away from the original tumor and forming new tumors elsewhere. Neuroblastoma often has no specific symptoms until it has metastasized, making it difficult to diagnose early and treat effectively.
