The nurse is caring for a client who requires IV fluids. which IV fluid type would be considered a hypertonic solution?
Tonic
Hypertonic
Hypotonic
Isotonic
The Correct Answer is B
Hypertonic solutions have a higher concentration of solutes (such as sodium, glucose, or mannitol) than the fluid in the body's cells, causing water to move out of the cells and into the bloodstream. This results in the shrinking of the cells and an increase in extracellular fluid volume.
Examples of hypertonic solutions include 10% dextrose in water (D10W), 3% saline, and 5% dextrose in 0.9% saline.
In contrast, isotonic solutions have the same concentration of solutes as the fluid in the body's cells, and hypotonic solutions have a lower concentration of solutes than the fluid in the body's cells.
Therefore, in this scenario, the nurse should administer a hypertonic solution to the client who requires IV fluids.

Correct Answer is B
Explanation
Hyponatremia is a condition where the sodium levels in the blood are abnormally low. It can cause confusion, seizures, and even coma in severe cases. The IV fluids hanging are 0.33% NaCI, which means they have a low sodium concentration, and may be contributing to the patient's hyponatremia.
Given that the patient is becoming increasingly confused, it is important to assess his mental status and monitor him closely to prevent harm. However, restraining the patient should not be the first course of action. Instead, the nurse should focus on identifying the underlying cause of the hyponatremia and taking appropriate steps to address it.
Therefore, the next step would be to get an order for additional lab work to assess the patient's electrolyte levels and identify the cause of the hyponatremia. This will help to guide further treatment and management decisions for the patient.
Correct Answer is A
Explanation
Before pumping the medication into the chamber, you should educate the patient to exhale. This means that the patient should breathe out fully before using the inhaler. This helps to empty the lungs of air and create more space for the medication to be inhaled.
