A nurse is preparing to administer 4,000 units of heparin subcutaneously to a client who has deep-vein thrombosis. Available in 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.)

Answer and Explanation

The Correct Answer is ["0.4"]

To calculate the volume of heparin needed, you can use the formula:

Volume (mL) = Desired dose (units) / Concentration (units/mL)

In this case, the desired dose is 4,000 units and the concentration is 10,000 units/mL.

Volume = 4,000 units / 10,000 units/mL = 0.4 mL

So, the nurse should administer 0.4 mL of heparin.

Correct Answer is D

Explanation

A. Decreased vomiting: This might improve as a result of the hypertonic solution treatment, but it is not a specific indicator of improved sodium levels.
B. Cardiac arrhythmias absent: While improvement in serum sodium levels can help prevent cardiac arrhythmias associated with hyponatremia, the absence of arrhythmias does not necessarily indicate that the sodium levels have normalized.
C. Absent Chvostek's sign: Chvostek's sign is associated with hypocalcemia, not hyponatremia. It is not directly related to the effectiveness of hypertonic solution treatment for hyponatremia.
D. Improved cognition
A nurse is caring for a client who has hyponatremia and is receiving an infusion of a prescribed hypertonic solution. The nurse should assess for improved cognition as an indicator that the treatment is effective.
Hyponatremia is a condition characterized by low levels of sodium in the blood. Hypertonic solutions, which have a higher concentration of solutes, are used to raise serum sodium levels. When the sodium levels return to a normal range, the client's cognitive function, including mental clarity and awareness, should improve. Other signs of improvement in hyponatremia include the resolution of symptoms related to fluid and electrolyte imbalance, such as nausea, vomiting, and muscle weakness.

A. Administer the medication into the client's muscle. B. Apply firm pressure to the injection site following administration. C. Insert the syringe needle halfway into the client's skin. D. Expel the air bubble from the syringe prior to injection
