A nurse is caring for a 6-month-old infant who is postoperative following a myringotomy. Which of the following pain scales should the nurse use to determine the infant's pain level?

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: Applying heat to a bleeding site can increase blood flow and worsen the bleeding. This statement indicates a need for further teaching, as the parent should avoid applying heat and use cold compresses instead.

Choice B: Having the child rest can reduce physical activity and prevent further injury or bleeding. This statement indicates that the parent understands the teaching, as resting is one of the recommended actions for controlling a minor bleeding episode.

Choice C: Compressing the site can apply pressure and stop the bleeding. This statement indicates that the parent understands the teaching, as compressing is one of the recommended actions for controlling a minor bleeding episode.

Choice D: Elevating the affected part can reduce blood pressure and slow down the bleeding. This statement indicates that the parent understands the teaching, as elevating is one of the recommended actions for controlling a minor bleeding episode.
