The physician orders 500 mg PO of medication. The Medication is supplied as a suspension 125 mg/5mL. How many mL will the nurse administer for one dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["20"]

Step-by-Step Solution:

Calculate the volume of medication to administer.

The available medication is 125 mg/5 mL.

We need to administer 500 mg.

To find the volume, we can set up a proportion:

125 mg / 5 mL = 500 mg / x mL

Cross-multiplying:

125x = 500 x 5

Solving for x:

x = (500 x 5) / 125 = 20 mL

Correct Answer is A

Explanation

A. "Reports taking an extra dose each day of their anticholinesterase medication."
This client is at highest risk for developing a cholinergic crisis. A cholinergic crisis occurs when there is overdose or excessive stimulation of acetylcholine receptors due to too much anticholinesterase medication. Symptoms include muscle weakness, respiratory distress, salivation, sweating, and bradycardia. Taking an extra dose of the medication can result in an overdose of acetylcholine, triggering these symptoms. Therefore, this client is at the greatest risk for a cholinergic crisis.

B. "Is experiencing a respiratory infection and is short of breath."
While respiratory infections can worsen symptoms of myasthenia gravis due to increased muscle weakness, this client is not directly at risk for a cholinergic crisis. Respiratory infections can increase the risk of myasthenic crisis, which is a different complication where muscle weakness worsens to the point of respiratory failure. A myasthenic crisis is caused by insufficient anticholinesterase medication or a disease exacerbation, not an overdose.

C. "Has a family history of autoimmune disorders."
A family history of autoimmune disorders may suggest a genetic predisposition to autoimmune diseases, but it does not increase the risk of a cholinergic crisis specifically. The risk of a cholinergic crisis is more directly related to medication management, not family history.

D. "Has a past medical history of type 2 diabetes mellitus."
Type 2 diabetes mellitus does not directly increase the risk of a cholinergic crisis. While diabetes may influence overall health and immune function, it does not have a direct impact on anticholinesterase therapy or the risk of cholinergic crisis in myasthenia gravis.

Correct Answer is ["89.8"]

Explanation

Step-by-Step Solution:

Convert the client's weight from pounds to kilograms.

1 pound is= 0.453592 kilograms.

220 pounds = 220 x 0.453592 = 99.7664 kilograms.

Calculate the total dose of Alteplase.

The prescribed dose is 0.9 mg/kg.

The client weighs 99.7664 kg.

The total dose = 0.9 mg/kg x 99.7664 kg = 89.8 mg.

Compare the calculated dose with the maximum dose.

The calculated dose (89.8 mg) is less than the maximum dose (90 mg).

Round the answer off to the nearest tenth:

89.9 mg
