Order: Metoprolol 2.5mg IV push
On hand: 1mg/mL vials
How many millilitres will the nurse draw up for this dose?
The Correct Answer is ["2.5"]
To find the number of milliliters that the nurse will draw up for this dose, we need to use the following formula:
Volume = Dose/Concentration
In this case, the dose is 2.5 mg and the concentration is 1 mg/mL. So, we plug in these values into the formula and get:
Volume= 2.5 mg /(1 mg/mL)
To simplify this fraction, we can divide both the numerator and the denominator by the same unit (mg) and get:
Volume = 2.5 /1 mL
Now, we can reduce this fraction by dividing both the numerator and the denominator by their greatest common factor, which is 1, and get:
Volume = 2.5 mL
Therefore, the nurse will draw up 2.5 mL of metoprolol for this dose.

Correct Answer is D
Explanation
Choice A reason: This statement is false. The client does not need to wear light clothing or avoid hot showers after receiving radioactive iodine. However, the client should avoid close contact with others, especially children and pregnant women, for a few days to prevent radiation exposure.
Choice B reason: This statement is false. The procedure is unlikely to leave the client infertile, as the dose of radioactive iodine is low and does not affect the reproductive organs. However, the client should avoid pregnancy for at least 6 months after the procedure, as a precaution.
Choice C reason: This statement is false. The client does not need to avoid caffeinated beverages after receiving radioactive iodine. However, the client should drink plenty of fluids to flush out the excess iodine from the body.
Choice D reason: This statement is true. The procedure is very likely to cause hypothyroidism, as the radioactive iodine destroys the thyroid cells that produce thyroid hormones. The client will need to take thyroid hormone replacement therapy for the rest of their life to prevent symptoms of hypothyroidism, such as fatigue, weight gain, cold intolerance, and depression.
Correct Answer is D
Explanation
Choice A reason: This statement is false. The nurse does not need to assess the client's sulfa allergy prior to giving nifedipine, as nifedipine is not a sulfa drug. Sulfa drugs are a group of antibiotics that contain the sulfonamide group and can cause allergic reactions in some people. Nifedipine is a calcium channel blocker that does not contain sulfonamide.
Choice B reason: This statement is false. The nurse does not need to assess the client's hemoglobin prior to giving nifedipine, as nifedipine does not affect the hemoglobin level. Hemoglobin is a protein in the red blood cells that carries oxygen to the tissues. Nifedipine is a calcium channel blocker that relaxes the blood vessels and improves the blood flow to the heart.
Choice C reason: This statement is false. The nurse does not need to assess the client's PTT prior to giving nifedipine, as nifedipine does not affect the blood clotting time. PTT stands for partial thromboplastin time, which is a test that measures how long it takes for the blood to clot. Nifedipine is a calcium channel blocker that does not interfere with the coagulation cascade.
Choice D reason: This statement is true. The nurse should assess the client's blood pressure prior to giving nifedipine, as nifedipine is a medication that lowers the blood pressure. The nurse should check the blood pressure and compare it with the baseline and the target values. The nurse should hold the nifedipine and notify the prescriber if the blood pressure is too low or too high. The nurse should also monitor the client's blood pressure after giving the nifedipine and report any changes.
