A nurse is preparing to administer 4,000 units of heparin subcutaneously to a client who has deep-vein thrombosis.
Available is heparin 10,000 units/mL.
How many mL of heparin should the nurse administer? (Round the answer to the nearest) tenth.
Use a leading zero if it applies.
Do not use a trailing zero.) mL.
The Correct Answer is ["0.4"]
To calculate the amount of heparin to administer, use the formula:
mL of heparin=units available units ordered×1mL available
Substituting the values given in the question, we get:
mL of heparin=100004000×11=0.4
Therefore, the nurse should administer 0.4 mL of heparin.
Normal ranges for heparin therapy vary depending on the condition being treated and the laboratory method used to measure APTT.
A general range is 60 to 80 seconds or 1.5 to 2.5 times the control value.

Correct Answer is C
Explanation
Methimazole is an antithyroid medication that blocks the thyroid from making thyroid hormones. It is used to treat hyperthyroidism caused by Graves’ disease, which is an autoimmune disorder that stimulates the thyroid gland to produce excess hormones. After taking methimazole for 2 months, the client should expect to see a reduction in the symptoms of hyperthyroidism, such as weight loss, increased pulse rate, and heat intolerance. Increased sleeping is a sign of improved thyroid function, as hyperthyroidism can cause insomnia and restlessness.
Choice A is wrong because weight loss is a symptom of hyperthyroidism, not a result of methimazole treatment. Methimazole should lower the thyroid hormone levels and help the client gain weight.
Choice B is wrong because an increase in pulse rate is also a symptom of hyperthyroidism, not a result of methimazole treatment. Methimazole should lower the heart rate and blood pressure by reducing thyroid hormone levels.
Choice D is wrong because warmer skin is another symptom of hyperthyroidism, not a result of methimazole treatment. Methimazole should improve the client’s heat tolerance and make the skin cooler and less sweaty.
Correct Answer is A
Explanation
This is because the umbilicus is a potential site of infection and should be avoided when administering subcutaneous heparin.
Choice B is wrong because massaging the site after administering the medication can cause bruising and hematoma formation.
Choice C is wrong because a 21-gauge needle is too large for subcutaneous injection and can cause tissue trauma and bleeding.
A smaller needle, such as 25- or 27-gauge, should be used.
Choice D is wrong because aspirating before injecting the medication can increase the risk of hematoma formation and is not recommended for subcutaneous heparin.
