When should the nurse reassess a client after administering 0.4 mg nitroglycerin sublingual to a client with chest pain?
30 minutes
5 minutes
1 hour
15 minutes
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.

Explanation
To calculate the amount of tobramycin that the nurse should administer per dose, we can use the following steps:
Calculate the total daily dosage required based on the client's weight and the prescribed dosage.
Determine the dosage per each of the three divided doses.
Calculate the volume of the drug needed for each dose using the concentration of the available tobramycin solution.
Given:
Client's weight = 85 kg
Prescribed dosage = 3 mg/kg/day
Available concentration of tobramycin = 40 mg/mL
Let's calculate step by step:
Calculate the total daily dosage required:
Total daily dosage = 3 mg/kg/day × 85 kg = 255 mg/day
Determine the dosage per each of the three divided doses:
Dosage per dose = Total daily dosage / 3 = 255 mg / 3 = 85 mg
Calculate the volume of the drug needed for each dose using the concentration of the available tobramycin solution:
Volume of drug per dose = Dosage per dose / Concentration of tobramycin
Volume of drug per dose = 85 mg / 40 mg/mL ≈ 2.1 mL
Rounding to the nearest tenth, the nurse should administer 2.1 mL of the tobramycin per dose.
Correct Answer is ["0.75"]
Explanation
To calculate the amount of heparin to administer, we can use the following formula:
Amount to administer (mL) = (Desired dose (units) / Available dose (units/mL))
Plugging in the given values:
Amount to administer (mL) = (7,500 units / 10,000 units/mL)
Now, let's solve for the amount to administer:
Amount to administer (mL) = (7,500 / 10,000) = 0.75 mL
So, the nurse should administer 0.75 mL of heparin subcutaneously.
