<16
Pregunta 14
Pregunta
Protein-energy malnutrition is moreso due to a general lack of food as opposed to a specific deficiency.

-
Underweight
-
Kwashiorkor
-
Marasmus
-
Marasmic kwashiorkor
Pregunta 16
Pregunta
Check all the boxes that give a typical presentation for a child with marasmus.
Pregunta 17
Pregunta
Marasmic kwashirokor is a combination of the two conditions, marasmus and kwashiorkor, in which the child may switch between forms.
Pregunta 18
Pregunta
Which of the following are typical presentations of a child with kwashiorkor?
Pregunta 19
Pregunta
Children with kwashiorkor exhibit [blank_start]banding[blank_end] of their hair. This is because, during periods of [blank_start]starvation[blank_end], the colour and texture of the hair is lost. During [blank_start]feeding[blank_end] periods, the colour and texture is regained. When these different periods occur in cycles, the hair appears [blank_start]banded[blank_end].
Respuesta
-
starvation
-
feeding
-
banded
-
banding
Pregunta 20
Pregunta
Marasmus occurs in developing countries due to [blank_start]chronic[blank_end] food shortages or [blank_start]acute[blank_end] famine. It can also occur in developed countries in disadvantaged groups and in [blank_start]disease[blank_end] such as cancer or AIDS.
Kwashiorkor is caused by general food deficiency with added deficiency of [blank_start]antioxidant[blank_end] nutrients. This leads to an inability to cope with added [blank_start]infection[blank_end].
Respuesta
-
chronic
-
acute
-
disease
-
antioxidant
-
infection
Pregunta 21
Pregunta
The oedema in kwashiorkor is painless and exhibits pitting.
Pregunta 22
Pregunta
When treating PEM...
1. Balance fluid and electrolytes with [blank_start]oral rehydration solution[blank_end]
2. [blank_start]Dextrose[blank_end] solution
3. [blank_start]Dilute[blank_end] milk
4. Normal food when tolerated
Pregunta 23
Pregunta
Why can you not give a patient with PEM normal food straight away?
Respuesta
-
Sudden feeding can deplete intracellular stores due to rapid glycogen, fat and protein synthesis (can be fatal)
-
Their GI tract may be damaged and unable to tolerate it
-
They will have no gastric acid so will have no mechanism to kill pathogens in the food
-
Their pancreas will be unable to secrete pancreatic juice containing the necessary digestive enzymes
Pregunta 24
Pregunta
Oral rehydration solution consists of a makeup of [blank_start]8[blank_end] teaspoons of sugar and [blank_start]1[blank_end] teaspoon of salt in [blank_start]1[blank_end] litre of [blank_start]boiled[blank_end] water.
Pregunta 25
Pregunta

Pregunta 26
Pregunta
