The healthcare provider prescribes dalteparin 200 units/kg SUBQ once a day for a client who weighs 154 lb. The medication is available in 25,000 units/mL vial. How many mL should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["0.6"]
Rationale:
- Convert the client's weight from pounds (lb) to kilograms (kg).
Weight in kg = 154 lb / 2.2 lb/kg
= 70 kg.
- Calculate the total desired dose in units.
Desired dose (units) = Desired dose (units/kg) × Weight (kg)
= 200 units/kg × 70 kg
= 14000 units.
Available concentration of the medication = 25,000 units/mL.
- Calculate the volume in milliliters (mL) to administer.
Volume (mL) = Desired dose (units) / Available concentration (units/mL)
= 14000 units / 25000 units/mL
= 0.56 mL.
- Round the answer to the nearest tenth.
= 0.6.

Correct Answer is B,A,D,C
Explanation
1. B. Verify the insulin prescription: The first step is to verify the prescription to ensure the correct type and dose of insulin before administering it. This ensures one is following the appropriate instructions.
2. A. Obtain blood glucose level: The next step is to check the client's blood glucose level to determine the amount of insulin needed based on the sliding scale.
3. D. Cleanse the selected site: After obtaining the blood glucose level, the next step is to prepare the injection site by cleaning it properly to prevent infection.
4. C. Draw insulin into insulin syringe: Finally, drawing the appropriate amount of insulin into the syringe, based on the sliding scale and the blood glucose level, to administer the injection.
Correct Answer is C
Explanation
A. Type of anticonvulsant prescribed: While the class or type of anticonvulsant influences seizure control, it does not directly indicate whether the client is receiving a sufficient dosage. The therapeutic effectiveness depends more on blood concentration than classification.
B. History of a recent illness: Acute illness can temporarily lower the seizure threshold, but it is a less specific indicator for predicting recurrence than pharmacologic control. The underlying condition must be assessed, but medication levels are more predictive of seizure risk.
C. Therapeutic level of medication: A subtherapeutic drug level is a strong predictor of seizure recurrence. Maintaining an adequate plasma concentration ensures optimal seizure control and is crucial in clients recovering from status epilepticus, where precise management is essential.
D. Duration of previous seizure activity: The length of the prior seizure can indicate severity but not the likelihood of recurrence. Even brief seizures can recur if anticonvulsant levels are inadequate, so duration is not as clinically useful as drug level monitoring.
