Nurses' Notes
Outpatient Clinic
Initial
visit
The child recently started attending a new preschool and hit a teacher during lunch. The parent says,
"My
child has never been aggressive before but has always been particular about food."
The client was born at full term without complications and has no significant medical history. The child
started babbling at age 6 months, and the parent reports that the first words were spoken around age 12
months. The client then became quiet and "obsessed" with stacking blocks and organizing toys by color.
The child can kick a ball, draw a circle, pedal a tricycle, and now says two-word phrases. Vitals signs are
normal, and the client is tracking adequately on growth curves.
During the evaluation, the child sits in the corner of the room playing with blocks. The client does not follow
the parents gaze when the parent points to toys in the office. The child begins screaming and rocking back
and forth when the health care provider comes near.

The nurse suspects the client is experiencing acute decompensated heart failure. Which of the following findings are consistent with this condition? Select all that apply.

  • A. Crackles with auscultation
  • B. Decreased capillary oxygen saturation
  • C. Elevated b-type natriuretic peptide
  • D. Left ventricular ejection fraction 30%
  • E. Lower extremity pitting edema
Correct Answer: A,B,C,D,E

Rationale: The findings all support the diagnosis of acute decompensated heart failure (ADHF):

Crackles with auscultation: Indicative of pulmonary congestion due to fluid overload.

Decreased capillary oxygen saturation: Reflects impaired gas exchange from fluid in the lungs.

Elevated B-type natriuretic peptide (BNP): A level of 640 pg/mL is significantly elevated; BNP is released when the ventricles are stretched due to increased fluid volume.

Left ventricular ejection fraction of 30%: Normal is 55–70%. This reduced EF confirms systolic dysfunction, common in ADHF.

Lower extremity pitting edema: A classic sign of volume overload in right-sided or total heart failure.
