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.

For each finding below, click to specify if the finding is consistent with the expected action of the medication carvedilol, enalapril, or furosemide. Each finding may support more than one medication.

  • A. Decreases heart rate
  • B. Increases urinary output
  • C. Decreases blood pressure
  • D. Increases oxygen saturation
Correct Answer:

Rationale: Pharmacologic management of heart failure (HF) focuses on reducing cardiac workload and improving cardiac output.
• Beta-adrenergic antagonists ("beta blockers") (eg, carvedilol) reduce cardiac workload by inhibiting the action of
catecholamines (eg, epinephrine, norepinephrine) on beta-adrenergic receptors in the heart. Beta blockers decrease
myocardial oxygen demand by decreasing blood pressure and decreasing heart rate.
• Angiotensin-converting enzyme (ACE) inhibitors (eg, enalapril) alter the renin-angiotensin-aldosterone system by
inhibiting conversion of angiotensin I to angiotensin II, thereby preventing the release of aldosterone. Aldosterone, an
adrenal steroid hormone, retains sodium and water in addition to promoting vasoconstriction. By reducing circulating
aldosterone, ACE inhibitors promote vasodilation and as a result decrease blood pressure. ACE inhibitors also
decrease ventricular remodeling, an added benefit for clients with HF.
• Loop diuretics (eg, furosemide) prevent reabsorption of sodium and chloride in the kidneys, which increases urine
output and fluid excretion. Decreases in circulating fluid volume will decrease blood pressure and reduce pulmonary
edema (ie, increase oxygen saturation), as well as decrease cardiac preload.
