A client who weighs 110 lbs has received a prescription for dalteparin, 150 units/kg to be administered subcutaneously daily for 4 months. The medication is available in a 7,500 units/0.3 mL prefilled syringe. How many mL should the nurse administer? (Please enter the numerical value only.)

Answer and Explanation

The Correct Answer is ["0.3"]

Step 1: Convert the client's weight from lbs to kg using the conversion factor you provided (1 kg = 2.2 lbs).

So, 110 lbs × (1 kg ÷ 2.2 lbs) = 50 kg

Step 2: Calculate the daily dosage of dalteparin in units using the prescription (150 units/kg).

So, 50 kg × 150 units/kg = 7500 units

Step 3: Determine how many mL of the medication this dosage corresponds to using the information on the syringe (7500 units/0.3 mL).

So, 7500 units × (0.3 mL ÷ 7500 units) = 0.3 mL

The nurse should administer 0.3 mL of dalteparin to the client.

Correct Answer is C

Explanation

Choice A reason: Cooling the bottle is not necessary and shaking it is only required if the instructions specify to do so to mix the medication.

Choice B reason: Inserting the tip of the dropper into the ear canal is not recommended as it can introduce bacteria and cause injury.

Choice C reason: Pulling the pinna up and back in adults helps to straighten the ear canal, allowing for proper delivery of the medication.

Choice D reason: Administering the drops with the head held upright is not the correct method; the head should be tilted to allow the drops to flow down into the ear canal.

A. Assess bilateral breath sounds. B. Palpate the suprapubic region for urinary retention. C. Review the client's daily medications. D. Initiate neurological monitoring every 2 hours.

Correct Answer is D

Explanation

Choice A reason: While assessing breath sounds is part of a comprehensive evaluation, it is not the most critical intervention for a TIA, which primarily affects neurological function.

Choice B reason: Palpating the suprapubic region for urinary retention is important but not the priority intervention for a client with TIA, as it does not directly relate to the risk of stroke.

Choice C reason: Reviewing the client's daily medications is necessary for overall care but is not the most immediate concern upon admission for a TIA.

Choice D reason: Initiating neurological monitoring every 2 hours is essential for a client with TIA to promptly identify any changes or progression in neurological status, which could indicate a stroke. This is the most important intervention to include in the plan of care for a client admitted with TIA. Neurological monitoring allows for immediate intervention if the client's condition worsens, potentially preventing further ischemic damage.
