Q.5) A 23-month-old female is hospitalized for severe
malnutrition. Which of the following problems is most likely to be the result
of inappropriately rapid treatment of the severely malnourished child?
(A) hyperkalemia
(B) hyponatremia
(C) hyperglycemia
(D) congestive heart failure
(E) renal failure
(A) hyperkalemia
(B) hyponatremia
(C) hyperglycemia
(D) congestive heart failure
(E) renal failure
Ans: (D)
Congestive heart
failure is very easy to precipitate in a severly malnourished child particulary
if colloid (blood) or crystalloid (sodium) is infused aggressively. Because the
heart is malnourished, contractility and therefore cardiac output is already
impaired. By increasing plasma volume
which would occur by infusing either of the above substances, the preload to the heart would
increase in the face of animpaired pump, resulting in congestive heart failure.
