A client receives a prescription for dalteparin 2500 units subcutaneously 2 hours before a scheduled procedure. The medication is available in a 5000 units/0.2 mL prefilled syringe. How many mL should the nurse administer? (Enter numeric value only)
The Correct Answer is ["0.1"]
To find out how many mL of dalteparin are needed for 2500 units, we need to use a proportion formula:
- (units of dalteparin)/(mL of dalteparin) = (units of dalteparin prescribed)/(mL of dalteparin needed)
- We can plug in the values that we know into the formula:
- (5000 units)/(0.2 mL) = (2500 units)/(x mL)
- We can cross-multiply and solve for x:
- 5000x = 2500 x 0.2
- x = (2500 x 0.2)/5000
- x = 0.1
- Therefore, the nurse should administer 0.1 mL of dalteparin to deliver 2500 units of the medication.

Correct Answer is C
Explanation
Choice B reason:While spironolactone can sometimes cause side effects, bruising is not a typical issue associated with this medication.
Choice A reason: Covering your skin before going outside is not an instruction that the nurse should include in this client's plan of care, but rather a general precaution that anyone should take to protect their skin from sun damage. Spironolactone does not increase the risk of sunburn or photosensitivity.
Choice C reason:Spironolactone is a potassium-sparing diuretic that works by blocking aldosterone, which helps reduce fluid retention. However, because it spares potassium, there is a risk of hyperkalemia (high potassium levels). Therefore, clients taking spironolactone should limit their intake of high-potassium foods (e.g., bananas, oranges, spinach, avocados) to avoid dangerous potassium levels.
Choice D reason: Replacing salt with a salt substitute is not an instruction that the nurse should include in this client's plan of care, but rather a dangerous practice that can lead to hyperkalemia. Salt substitutes are often made with potassium chloride, which can increase the potassium level in the blood. The client should use herbs or spices instead of salt or salt substitutes to flavor their food.
