scenario 2

The following blood work results were obtained:

Thyroid Function Tests:

T4: 4.5 µg/dl

T3: 70 ng/dl

TSH: 5.4 IU/L

Electrolytes:

Chloride: 100mEq/L

Potassium: 4.9 mEq/L

Sodium: 125 mEq/L

Calcium: 11.2 mg/dl

Magnesium: 1.5 mg/dl

Phosphorus: 2.0 mg/dl

Based on the information provided above in Scenario answer the following question: List specific values from the blood work related to the thyroidectomy.

Answer 1

1.Given

Medication:Desmopressin acetate

Dose:2mcg

Available:4mcg/ml

When 1ml =4mcg

Then ??ml=2mcg

Cross multiply and divide

=2×1÷4

=0.5

Ans:0.5ml

2.Given

Order:1000mg of calcium and 600 units of vitamin D

Available:Calcium carbonate -vitamin D3 250mg-125units

It means 1 tablet has 250mg of calcium and 125 units of vitamin D

Now to calculate the number of tablet in a simpler way

Calcium carbonate:1000÷250=4 and vitamin D:600÷125=4

Ans :4 tablets

3.Available:25mg

Order:75mg

When one tablet =25mg then 75mg will be 75÷25 =3

Ans:3 tablets

●The specific values in related to thyroidectomy are

T4(5_12mcg/dL)

T3(100 _200 nanograms/dL)

TSH(0.5 _0.3IU/L)

In thyroidectomy the levels are near to normal or below normal range

Other

Sodium (135_145)patient has hyponatremia

Calcium:(8.3 _10.6mg/dl) elevated

Phosphorus:(2.5_4.5mg/dl) decreased
