A 22-year-old dialysis patient presents to the ER with chest pain and palpitations. Laboratory tests reveal a Potassium (K+) level of 7.0 mEq/L. Which electrolyte imbalance is the patient suffering from?

A. A filter needle is used when withdrawing medication from an ampule, but it is not used to administer the injection. After withdrawal, the filter needle should be replaced with a regular IM needle for administration.
B. The ampule should be broken by snapping the neck away from the body, not by bending it to the side, to prevent injury.
C. The nurse should gently tap the top of the ampule, not the bottom, to move the solution downward before opening.
D. The correct technique is to insert the needle into the center of the ampule to withdraw medication, ensuring that the bevel remains below the fluid line to avoid drawing up air.

B. Dextrose 10% in water is a solution that contains a high concentration of glucose (dextrose). Infusing D10W can lead to an increase in blood glucose levels, especially if the client's body cannot metabolize the glucose effectively (e.g., in diabetic patients or those with impaired glucose tolerance).

A. Dextrose 10% in water does not contain calcium. Hypercalcemia refers to elevated calcium levels in the blood, which can occur due to various causes such as hyperparathyroidism or excessive vitamin D intake, but not from D10W infusion.

C. Dextrose 10% in water is not used to treat hypovolemia (low blood volume). It is a solution primarily used to provide calories and prevent ketosis rather than to expand circulating blood volume.

D. Dextrose 10% in water does not contain potassium. Hypokalemia (low potassium levels) can occur due to various reasons such as diuretic use, gastrointestinal losses, or inadequate intake, but it is not directly related to D10W infusion.
