<span>The nurse should tell the patient that eating a variety of healthy food is the best source of vitamins<span>. This is should be told by the nurse in a nice and emphatic manner, especially in this case wherein patients diagnosed with HIV are particularly emotionally sensitive. While this is true, the nurse should not advise the patient to stop taking his or her supplements; especially being diagnosed with HIV, his or her immune system is very frail and needs more than the usual nutrients compared to the normal population. </span></span>
        
             
        
        
        
Answer:
21.81grams
Explanation:
According to the question, an agar medium requires the following ingredients: 21 grams (g) of
agar, 500 mg of dextrose, 3 dg of sodium, and 1 cg of potassium per 1,000 milliliters (mL) of distilled water.
Hence, the dry ingredient contain 21grams (g) of agar, 500milligrams (mg) of dextrose, 3decigrams (dg) of Sodium, and 1centigrams (cg) of pottasium. 
We need to convert all units (not in grams (g)) to grams. 
1grams = 1000milligrams
500 milligrams = 500/1000
= 0.500grams.
1grams = 10decigrams
3decigrams = 3/10
= 0.3grams
1grams = 100centigrams
1centigrams = 1/100
= 0.01 grams
Therefore, we have 21g, 0.500g, 0.3g, and 0.01g
The total dry weight of the ingredients will be:
21 + 0.500 + 0.3 + 0.01
= 21.81grams
