A parent calls a clinic and reports to a nurse that his 2-month-old infant is hungry more than usual but is projectile vomiting immediately after eating. Which of the following responses should the nurse make?

Choice A: A 10-year-old child who has sickle cell anemia and reports severe chest pain should be assessed first, as this is a sign of acute chest syndrome, which is a life-threatening complication of sickle cell disease. Acute chest syndrome occurs when sickle-shaped red blood cells block the blood flow to the lungs, causing hypoxia, inflammation, and infection. Acute chest syndrome can lead to respiratory failure, pulmonary hypertension, or stroke.

Choice B: A 7-year-old child who has diabetes insipidus and a urine specific gravity of 1.016 should be assessed second, as this is a sign of dehydration, which is a common complication of diabetes insipidus. Diabetes insipidus is a condition in which the body does not produce enough antidiuretic hormone (ADH) or does not respond to it properly, resulting in excessive urination and thirst. Dehydration can cause electrolyte imbalance, hypotension, or shock.

Choice C: A 4-year-old child who has asthma and an O2 sat of 97% should be assessed third, as this is a sign of adequate oxygenation, which is a desired outcome of asthma management. Asthma is a condition in which the airways become inflamed, narrow, and produce excess mucus, causing difficulty breathing, wheezing, coughing, or chest tightness. Asthma can be triggered by allergens, irritants, exercise, or infections.

Choice D: A 1-year-old toddler who has roseola and a temperature of 39°C/102.2°F should be assessed last, as this is a sign of a mild viral infection, which is self-limiting and usually resolves within a week. Roseola is a common childhood illness that causes a high fever followed by a pink rash on the trunk, face, and limbs. Roseola can also cause irritability, swollen lymph nodes, or mild diarrhea.

Choice A: Encouraging the parents to rock the infant is an appropriate action for a nurse to take, as it can provide comfort, security, and bonding for the infant who is recovering from surgery. Rocking can also soothe the infant's pain and distress and promote sleep and relaxation.

Choice B: Administering blood thinners as needed for pain is not an appropriate action for a nurse to take, as blood thinners are not analgesics and can cause bleeding complications in an infant who is postoperative. Blood thinners are medications that prevent or reduce blood clotting, which can increase the risk of hemorrhage or hematoma. The nurse should administer analgesics, such as acetaminophen or ibuprofen, as prescribed by the provider for pain relief.

Choice C: Positioning the infant on her abdomen is not an appropriate action for a nurse to take, as it can cause pressure or trauma to the surgical site and increase the risk of infection or dehiscence. Positioning the infant on her abdomen can also impair the infant's breathing and oxygenation and increase the risk of sudden infant death syndrome (SIDS). The nurse should position the infant on her back or side with her head elevated and supported.

Choice D: Offering the infant a pacifier is not an appropriate action for a nurse to take, as it can cause suction or friction on the surgical site and increase the risk of infection or dehiscence. Offering the infant a pacifier can also interfere with the infant's feeding and nutrition and cause nipple confusion or preference. The nurse should avoid giving the infant anything in her mouth except for a bottle or breast with a special nipple that does not touch the surgical site.
