Answer and Explanation

The Correct Answer is ["0.3"]

Calculating the Lidocaine Dose

Problem: Administer 50 mg of lidocaine IV bolus. The available concentration is 200 mg/mL.

Steps:

Set up a proportion:

We want to find the number of milliliters (mL) needed.

We know the desired dose (50 mg) and the concentration of the medication (200 mg/mL).

Proportion:

x mL / 50 mg = 1 mL / 200 mg

Cross-multiply:

200x = 50

Solve for x:

x = 50 / 200

x = 0.25

Answer: The nurse should administer 0.3 mL of lidocaine per dose(rounded to the nearest tenth).

Calculating the Diphenhydramine Dose

Problem: Administer 25 mg of diphenhydramine elixir. The available concentration is 12.5 mg/5 mL.

Steps:

Set up a proportion:

We want to find the number of milliliters (mL) needed.

We know the desired dose (25 mg) and the concentration of the medication (12.5 mg/5 mL).

Proportion:

x mL / 25 mg = 5 mL / 12.5 mg

Cross-multiply:

12.5x = 125

Solve for x:

x = 125 / 12.5

x = 10

Answer: The nurse should administer 10 mL of diphenhydramine elixir per dose.

A. Discontinue medication if nausea occurs. B. Avoid driving until effects are known. C. Monitor for increased muscle spasms. D. Expect urine to turn orange.

Correct Answer is B

Explanation

A) Discontinue medication if nausea occurs:
While nausea can be a side effect of cyclobenzaprine, it is not typically a reason to discontinue the medication immediately. The client should contact their healthcare provider if they experience nausea or other side effects, but discontinuation should be based on medical advice.

B) Avoid driving until effects are known:
Cyclobenzaprine is a muscle relaxant that can cause drowsiness, dizziness, or impaired cognitive function. It is important for clients to avoid driving or operating heavy machinery until they are aware of how the medication affects them and if they can do so safely.

C) Monitor for increased muscle spasms:
Cyclobenzaprine is prescribed to reduce muscle spasms, so an increase in muscle spasms would be contrary to the intended effect of the medication. Clients should monitor for effectiveness and report any increase in symptoms to their healthcare provider.

D) Expect urine to turn orange:
Cyclobenzaprine does not typically cause urine to change color. Urine discoloration is not a common side effect of this medication. Clients should be informed about possible side effects, but urine discoloration is not associated with cyclobenzaprine.
