A client is being treated for heart failure. Labs: Sodium 146, Potassium 2.9, Hemoglobin 10.5, White Blood Cells 12.2 VS: BP 118/66, apical heart rate 68, O2 96% on 2L nasal cannula, temperature 98.4F
What will the nurse do with the digoxin order?
Recheck heart rate in one hour.
Hold the digoxin and call the MD.
Call prescriber and ask for chest x-ray.
Give the digoxin as ordered.
The Correct Answer is B
Choice A reason: This statement is false. The nurse should not delay the administration of digoxin based on the heart rate alone, unless it is below 60 beats per minute. The nurse should also consider the serum potassium level, which is low in this case and increases the risk of digoxin toxicity.
Choice B reason: This statement is true. The nurse should hold the digoxin and call the MD, as the client has a low potassium level, which can potentiate the effects of digoxin and cause arrhythmias, nausea, vomiting, or visual disturbances. The MD may order a serum digoxin level, potassium supplementation, or a dose adjustment.
Choice C reason: This statement is false. The nurse does not need to call the prescriber and ask for a chest x-ray, as this is not relevant to the digoxin order. A chest x-ray may be indicated to assess the severity of heart failure, but it does not affect the decision to administer digoxin.
Choice D reason: This statement is false. The nurse should not give the digoxin as ordered, as the client has a low potassium level, which can increase the risk of digoxin toxicity. The nurse should hold the digoxin and call the MD for further instructions..

Correct Answer is ["2.5"]
Explanation
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 ["A","B","C"]
Explanation
Choice A reason: This statement is true. Atenolol is a beta blocker, which is a type of medication that blocks the effects of adrenaline on the beta receptors in the heart and blood vessels. This lowers the blood pressure and heart rate, and prevents angina and heart attacks.
Choice B reason: This statement is true. Labetalol is a beta blocker, which is a type of medication that blocks the effects of adrenaline on both the alpha and beta receptors in the heart and blood vessels. This lowers the blood pressure and heart rate, and prevents hypertension and preeclampsia.
Choice C reason: This statement is true. Metoprolol is a beta blocker, which is a type of medication that blocks the effects of adrenaline on the beta receptors in the heart and blood vessels. This lowers the blood pressure and heart rate, and prevents angina, heart failure, and arrhythmias.
Choice D reason: This statement is false. Captopril is not a beta blocker, but an angiotensin-converting enzyme (ACE) inhibitor, which is a type of medication that blocks the conversion of angiotensin I to angiotensin II, a hormone that constricts the blood vessels and raises the blood pressure. This lowers the blood pressure and prevents hypertension, heart failure, and kidney damage.
Choice E reason: This statement is false. Ramipril is not a beta blocker, but an angiotensin-converting enzyme (ACE) inhibitor, which is a type of medication that blocks the conversion of angiotensin I to angiotensin II, a hormone that constricts the blood vessels and raises the blood pressure. This lowers the blood pressure and prevents hypertension, heart failure, and stroke.
