A nurse in an emergency department is caring for an adult who is experiencing an acute asthma attack. Which of the following medications should the nurse expect to administer?

Choice A reason: This statement is incorrect, as giving an oral rehydration solution to an infant who is projectile vomiting may worsen the dehydration and electrolyte imbalance. The nurse should advise the parent to stop feeding the infant and seek medical attention.

Choice B reason: This statement is incorrect, as burping the baby more frequently during feedings may not prevent the projectile vomiting, which is caused by a mechanical obstruction of the stomach, not by air swallowing. The nurse should assess the parent for signs of pyloric stenosis, such as a palpable olive-shaped mass in the right upper quadrant of the abdomen.

Choice C reason: This statement is correct, as bringing the baby in to the clinic today is the best course of action for an infant who is projectile vomiting, which is a sign of a serious condition such as pyloric stenosis, a narrowing of the opening between the stomach and the small intestine. The nurse should inform the parent that the infant needs immediate evaluation and treatment to prevent complications such as dehydration, malnutrition, and metabolic alkalosis.

Choice D reason: This statement is incorrect, as trying switching to a different formula may not help the infant who is projectile vomiting, which is not related to the type of formula, but to a structural problem in the gastrointestinal tract. The nurse should not suggest changing the formula without consulting the provider.

Choice A reason: The child has signs of dehydration and hypovolemic shock, such as vomiting, melena, abdominal pain, and weak pedal pulses. Dehydration is a loss of fluid and electrolytes from the body, which can result from gastroenteritis. Hypovolemic shock is a life-threatening condition that occurs when the blood volume is too low to maintain adequate perfusion and oxygen delivery to the vital organs.

Choice B reason: The child does not have signs of peritonitis and septic shock, such as fever, chills, rigors, tachycardia, hypotension, and abdominal rigidity. Peritonitis is an inflammation of the peritoneum, the membrane that lines the abdominal cavity and organs. Septic shock is a severe infection that causes systemic inflammatory response syndrome and organ dysfunction.

Choice C reason: The child does not have signs of pancreatitis and cardiogenic shock, such as elevated serum amylase and lipase, jaundice, dyspnea, crackles, and chest pain. Pancreatitis is an inflammation of the pancreas, an organ that produces digestive enzymes and hormones. Cardiogenic shock is a failure of the heart to pump enough blood to meet the body's needs.

Choice D reason: The child does not have signs of peptic ulcer and anaphylactic shock, such as hematemesis, dyspepsia, urticaria, angioedema, and wheezes. Peptic ulcer is a sore in the lining of the stomach or duodenum, caused by factors such as Helicobacter pylori infection, NSAIDs, or stress. Anaphylactic shock is a severe allergic reaction that causes bronchoconstriction, vasodilation, and hypotension.
