The nurse understands that a patient with status asthmaticus will likely initially evidence symptoms of:

Correct Answer: C

Rationale: In status asthmaticus, a severe and prolonged asthma attack can lead to inadequate ventilation due to airway obstruction. This results in retention of carbon dioxide (CO2) in the blood, leading to respiratory acidosis. As the CO2 levels rise, it combines with water in the blood to form carbonic acid, lowering the blood pH levels. Symptoms of respiratory acidosis can include shortness of breath, confusion, lethargy, and potentially life-threatening complications. Treatment for status asthmaticus aims to improve ventilation and restore normal blood gas levels to alleviate respiratory acidosis.

Correct Answer: C

Rationale: Corticosteroids, such as prednisone, are commonly used in the treatment of juvenile rheumatoid arthritis (JRA) to reduce inflammation and pain. However, one of the complications associated with corticosteroid use is immune suppression. Corticosteroids can suppress the immune system by reducing the activity and effectiveness of white blood cells, making individuals more susceptible to infections. It is important for healthcare providers, including nurses, to educate adolescents and their families about the risks and possible complications of corticosteroid therapy, including immune suppression.

Correct Answer: D

Rationale: Diabetic ketoacidosis (DKA) is a potentially life-threatening complication of diabetes characterized by hyperglycemia, ketosis, and metabolic acidosis. The initial treatment for DKA requires correcting dehydration and electrolyte imbalances. Normal saline infusion is the preferred choice for initial fluid resuscitation in patients with DKA to address dehydration and restore intravascular volume. It helps improve organ perfusion and correct electrolyte imbalances such as hyponatremia and dehydration commonly seen in DKA patients. Administering normal saline helps replace lost fluids and improve circulation, which is crucial in the management of DKA. Potassium infusion may be needed later to replete potassium levels once the patient's kidney function has been assessed. NPH insulin infusion is not the initial treatment for DKA, although insulin therapy is an essential component of DKA management. 5% dextrose infusion is contraindicated in the initial treatment

Correct Answer: C

Rationale: Positioning the child on his right side after surgery for pyloric stenosis helps to promote the flow of formula through the pylorus and into the intestines. Placing the child in this position can aid in preventing any potential complications from the surgery and promote proper digestion. The right side position assists in the drainage of the stomach contents, thereby reducing the risk of complications related to the surgery and promoting the healing process. It is essential to follow this positioning recommendation as part of the post-operative care for a child who has undergone surgery for pyloric stenosis.

Correct Answer: A

Rationale: The most dangerous complication of untreated hypothyroidism is mental retardation, especially in infants and children. Thyroid hormones play a vital role in the brain development of infants and young children. Severe and prolonged hypothyroidism during this critical period can lead to irreversible cognitive impairment, affecting intelligence and neurodevelopment. Therefore, timely diagnosis and treatment of hypothyroidism are essential to prevent this serious complication, particularly in children.
