17-18.4
-
16-17

<16
Frage 14
Frage
Protein-energy malnutrition is moreso due to a general lack of food as opposed to a specific deficiency.
Frage 15
Frage

Antworten
-
Underweight
-
Kwashiorkor
-
Marasmus
-
Marasmic kwashiorkor
Frage 16
Frage
Check all the boxes that give a typical presentation for a child with marasmus.
Frage 17
Frage
Marasmic kwashirokor is a combination of the two conditions, marasmus and kwashiorkor, in which the child may switch between forms.
Frage 18
Frage
Which of the following are typical presentations of a child with kwashiorkor?
Frage 19
Frage
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].
Antworten
-
starvation
-
feeding
-
banded
-
banding
Frage 20
Frage
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].
Antworten
-
chronic
-
acute
-
disease
-
antioxidant
-
infection
Frage 21
Frage
The oedema in kwashiorkor is painless and exhibits pitting.
Frage 22
Frage
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
Frage 23
Frage
Why can you not give a patient with PEM normal food straight away?
Antworten
-
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
Frage 24
Frage
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.
Frage 25
Frage
Non-starch polysaccharide foods are high in energy and low in bulk.
Frage 26
Frage
The essential fatty acids are precursors of eicosanois (prostaglandins, thromboxanes, prostacyclins)
