There is 500mg of potassium in 1 cup (240ml) of orange juice. Your renal patient must watch his potassium intake not to exceed 2 mg per kg of body weight per day from orange juice alone. How much juice (in mL) can this patient have per day if the patient weighs 135lbs?

The patient can take 58.7904  ml of juice daily

Step-by-step explanation:

There is 500 mg of potassium in 1 cup(240 ml) of orange juice.  The amount of potassium found in 240 ml of orange juice is 500 mg.

Let us convert the patient body weight to kg .

1 kg = 2.20462 Ib

? kg = 135 Ib

cross multiply

135/2.20462 = 61.2350427738 ≈ 61.24 kg

The patient weight in kg is 61.24.

The patient limits is 2 mg per kg of body weight per day from fruit juice. The patient limits with a weight of 61.24 kg will be 61.24 × 2 = 122.48 mg of potassium.

500 mg of potassium is in 240 ml of orange juice.

122.48 mg of potassium is ? of ml of orange juice

cross multiply

ml of orange juice = (122.48 × 240)/500

ml of orange juice = 29395.2 /500

ml of orange juice = 58.7904  ml

The patient can take 58.7904  ml of juice daily
