## Question

Stage 1 — Recognize cues. A 10-year-old child with sickle cell disease was admitted 12 hours ago for severe leg and back pain after poor oral intake during a sports tournament. The child now has a temperature of 38.7 C, a new cough, and chest pain. Click the findings that require immediate follow-up.

| Assessment | Finding 12 hours after admission |
| --- | --- |
| Leg and back pain | Rated 6/10, down from 9/10 at admission, on scheduled analgesia |
| Oxygen saturation | 89% on room air; 97% on room air at admission |
| Heart sounds | Grade II/VI systolic flow murmur noted at prior clinic visits |
| Hemoglobin | 6.9 g/dL; clinic baseline 8.4 g/dL |
| Eyes | Scleral icterus that the caregiver says is usual for the child |
| Level of consciousness | Drifts off mid-sentence since the third morphine dose |
| Reticulocyte count | Elevated, similar to prior clinic results |
| Urine | Specific gravity 1.010 despite poor intake before admission |
| Chest assessment | Splints on inspiration; diminished breath sounds at the right base |
| Indirect bilirubin | 3.1 mg/dL; clinic value 2.9 mg/dL |

## Explanation

The fall in saturation from 97% to 89%, right-base splinting with diminished breath sounds, a hemoglobin 1.5 g/dL below the child's own baseline, and drifting off mid-sentence after repeated morphine (opioid sedation in a hypoxemic child) are new changes that require immediate follow-up. Icterus, a mildly higher indirect bilirubin, an elevated reticulocyte count, a flow murmur, and low urine specific gravity are chronic consequences of hemolysis, anemia, and renal concentrating defects, and the limb pain is improving.

## In-depth explanation

Quick answer
Oxygen saturation, hemoglobin, level of consciousness, and chest assessment.

Why this is correct
The key skill is separating what is new from what is this child's baseline. Sickle cell disease produces chronic hemolysis (icterus, reticulocytosis), chronic anemia with a flow murmur, and hyposthenuria (inability to concentrate urine). None of these changed meaningfully; an indirect bilirubin of 3.1 against a clinic value of 2.9 mg/dL is within this child's usual hemolytic range. In contrast, oxygen saturation has dropped 8 points, the right base is splinted and poorly aerated, and hemoglobin has fallen 1.5 g/dL from the clinic baseline. Drifting off mid-sentence after the third morphine dose is opioid sedation (a POSS 3 level), not restful sleep; in a child who is already hypoxemic and splinting it can deepen hypoventilation and must be acted on now. Together with fever, cough, and chest pain these new changes signal a pulmonary complication that can progress within hours.

Easy analogy or mental picture
Imagine comparing today's photo of the child with the family album: the yellow eyes and murmur are in every picture, but the low oxygen, the quiet right lung, the lower hemoglobin, and the heavy sedation are new.

Memory hook
"Same as always = baseline; new since admission = act."

NCLEX decision rule
In chronic disease, prioritize findings that differ from the client's documented baseline or that appeared since the last assessment.

Why the other choices are wrong
Icterus, an elevated reticulocyte count, and an indirect bilirubin of 3.1 mg/dL look abnormal but reflect ongoing hemolysis that the caregiver and clinic records confirm is usual; the 0.2 mg/dL bilirubin difference is not a meaningful change. The flow murmur is common with chronic anemia and was documented before. A specific gravity of 1.010 despite poor intake seems contradictory, but children with sickle cell disease cannot concentrate urine, so it does not prove adequate hydration or a new problem. Pain falling from 9/10 to 6/10 indicates the vaso-occlusive episode is responding, but improving pain should not be confused with the sedation that the opioid doses are also producing.

## Clinical scenario

Case update
Twelve hours after admission for a pain crisis, the child develops fever, cough, and chest pain.

## Key concepts

- **Hyposthenuria** — Reduced ability to concentrate urine caused by sickling in the renal medulla, producing a low fixed specific gravity.
- **Hemolytic anemia baseline** — The chronic hemoglobin level a child with sickle cell disease usually maintains, used to judge whether a new value is an acute drop.
- **Splinting** — Voluntary limitation of chest expansion because of pain, which leads to hypoventilation of the affected lung region.
