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 A reason: Encouraging an increase in oral intake is not necessary in this situation, as dark urine is not a sign of dehydration or fluid imbalance. Dark urine may be caused by certain foods, medications, or medical conditions, but it does not indicate a need for more fluids.
Choice B reason: Measuring the client's urinary output is not relevant to this situation, as dark urine is not a sign of urinary retention or obstruction. Urinary output may vary depending on fluid intake, activity level, or other factors, but it does not reflect urine color.
Choice C reason: Explaining that color change is normal is the appropriate action to take, as dark urine is a common and harmless side effect of carbidopa/levodopa, which is a combination drug used to treat Parkinson's disease by increasing dopamine levels in the brain. Carbidopa/levodopa can cause urine to turn brown, black, or red, but this does not affect the function or health of the kidneys or bladder.
Choice D reason: Obtaining a specimen for a urine culture is not necessary in this situation, as dark urine is not a sign of infection or inflammation. A urine culture may be indicated if the client has symptoms such as fever, pain, burning, frequency, or urgency, but it does not diagnose urine color
Correct Answer is A
Explanation
Choice A reason: This is the correct action to include in the client's plan of care, as sucralfate should be given on an empty stomach, at least one hour before meals and at bedtime. Sucralfate is a mucosal protectant that forms a protective barrier over the ulcer and prevents further damage from acid and pepsin. It requires an acidic environment to work, so it should not be taken with food or antacids.
Choice B reason: This is not a relevant action to include in the client's plan of care, as sucralfate does not cause or increase the risk of secondary Candida infection. Candida infection is a fungal infection that can affect the mouth, throat, esophagus, or vagina. It is more common in clients who use antibiotics, corticosteroids, or immunosuppressants, but not sucralfate.
Choice C reason: This is not an accurate action to include in the client's plan of care, as sucralfate should be administered four times a day, not once a day. Sucralfate has a short duration of action, so it needs to be taken frequently to maintain its protective effect on the ulcer.
Choice D reason: This is not a necessary action to include in the client's plan of care, as sucralfate does not cause or affect electrolyte imbalance. Electrolyte imbalance is an abnormality in the levels of sodium, potassium, calcium, magnesium, or other minerals in the blood. It can be caused by dehydration, vomiting, diarrhea, kidney disease, or other conditions, but not sucralfate.
