When should the nurse reassess a client after administering 0.4 mg nitroglycerin sublingual to a client with chest pain?

A.

30 minutes

B.

5 minutes

C.

1 hour

D.

15 minutes

Answer and Explanation

The Correct Answer is B

Choice A reason: This is incorrect because 30 minutes is too long to wait for reassessing a client with chest pain. Nitroglycerin has a rapid onset of action and should relieve chest pain within 5 minutes. If not, the client may need another dose or emergency care.

Choice B reason: This is correct because 5 minutes is the appropriate time to reassess a client after administering nitroglycerin sublingual. The nurse should check the client's blood pressure, heart rate, and pain level. If the pain persists, the nurse should follow the protocol for giving another dose or calling for help.

Choice C reason: This is incorrect because 1 hour is too long to wait for reassessing a client with chest pain. Nitroglycerin has a short duration of action and may need to be repeated every 5 minutes for up to 3 doses. Waiting for an hour may put the client at risk of worsening cardiac ischemia or infarction.

Choice D reason: This is incorrect because 15 minutes is too long to wait for reassessing a client with chest pain. Nitroglycerin should have an effect within 5 minutes. If the pain is not relieved by then, the client may need another dose or emergency care.

Correct Answer is ["1.1"]

Explanation

To calculate the amount of cefazolin that the nurse should add to the 50 mL of 0.9% sodium chloride, we can use the following steps:

Calculate the amount of cefazolin needed to prepare the solution:

  • The concentration to be achieved is 225 mg/mL.
  • The required dose is 250 mg.

Calculate the volume of cefazolin needed:

  • 250 mg ÷ 225 mg/mL = 1.111... mL
  • Rounded to the nearest tenth, the nurse should add 1.1 mL of cefazolin to the 50 mL of 0.9% sodium chloride.

Therefore, the nurse should add 1.1 mL of cefazolin to the 50 mL of 0.9% sodium chloride to prepare the solution for IV administration.

Correct Answer is ["3"]

Explanation

To calculate the amount of hydrocortisone to administer, we can use the following formula:

Amount to administer (mL) = (Desired dose (mg) / Available dose (mg/mL))

Plugging in the given values:

Amount to administer (mL) = (150 mg / 50 mg/mL)

Now, let's solve for the amount to administer:

Amount to administer (mL) = (150 / 50) = 3 mL

So, the nurse should administer 3 mL of hydrocortisone via IV bolus.
