A nurse is caring for a toddler whose parent states that while bathing the child, she noticed a mass in his abdominal area and that his urine is a pink color. Which of the following actions is the nurse's priority?

Choice A reason: This statement does not indicate a risk for rheumatic carditis, but rather a possible respiratory infection or asthma. Rheumatic carditis is an inflammatory condition of the heart valves that can result from untreated streptococcal pharyngitis.

Choice B reason: This statement does not indicate a risk for rheumatic carditis, but rather a sign of heart failure. Dyspnea, tachypnea, and hypoxia are common manifestations of heart failure in children with congenital heart defects.

Choice C reason: This statement does not indicate a risk for rheumatic carditis, but rather a normal finding for a client who has an IV access. A peripheral saline lock is used to administer fluids and medications as needed, and it should be monitored for signs of infection, infiltration, or phlebitis.

Choice D reason: This statement indicates a risk for rheumatic carditis, as lower extremity edema and decreased skin pigmentation are signs of erythema marginatum, a characteristic rash that occurs in some cases of rheumatic fever. Erythema marginatum is a pink or red rash that spreads from the trunk to the extremities, and it may fade and reappear with changes in temperature.

Choice A reason: Acidic odors are not a sign of a perforated appendix, but rather a possible indication of gastroesophageal reflux disease (GERD), which is a condition that causes stomach acid to flow back into the esophagus¹.

Choice B reason: Sudden decrease in abdominal pain is a sign of a perforated appendix, which is a serious complication of acute appendicitis. When the appendix ruptures, the pressure inside the abdomen is released, causing a temporary relief of pain. However, this is followed by severe inflammation and infection of the peritoneum, which is the membrane that lines the abdominal cavity². This can lead to sepsis, shock, and death if not treated promptly.

Choice C reason: Narrow fever is not a term that is commonly used in medicine. Fever is a general sign of infection or inflammation, and it can be present in both acute appendicitis and perforated appendix. However, fever alone is not a reliable indicator of the severity or location of the problem³.

Choice D reason: Rigid abdomen is a sign of peritonitis, which is a possible consequence of a perforated appendix. Peritonitis causes the abdominal muscles to contract and become stiff, making the abdomen hard and tender to touch². However, rigidity can also occur in other conditions that cause intra-abdominal inflammation, such as pancreatitis or cholecystitis⁴.

Choice E reason: Nausea is a common symptom of acute appendicitis, but it is not specific to a perforated appendix. Nausea can be caused by irritation of the stomach or the nerves that control vomiting. It can also occur in other gastrointestinal disorders, such as gastritis or gastroenteritis⁵.
