A nurse is caring for a client who has atrial fibrillation and receives digoxin daily. Before administering this medication, which of the following actions should the nurse take?
Weigh the client.
Measure the client's blood pressure.
Measure the client's apical pulse.
Offer the client a light snack.
The Correct Answer is C
Choice A reason: Weighing the client is not a necessary action before administering digoxin, as it does not affect the dosage or effectiveness of the medication. Weighing the client may be important for monitoring fluid balance and edema, but it is not related to digoxin therapy.
Choice B reason: Measuring the client's blood pressure is not a necessary action before administering digoxin, as it does not affect the dosage or effectiveness of the medication. Digoxin is not a blood pressure-lowering medication, but a cardiac glycoside that increases the contractility and efficiency of the heart. Measuring the blood pressure may be important for monitoring hypertension, but it is not related to digoxin therapy.
Choice C reason: Measuring the client's apical pulse is a necessary action before administering digoxin, as it can help determine the safety and appropriateness of the medication. Digoxin can cause bradycardia (slow heart rate) as a side effect, which can be dangerous and symptomatic. The nurse should check the apical pulse for one full minute and withhold the medication if the pulse is below 60 beats per minute or above 100 beats per minute. The nurse should also report any abnormal or irregular rhythms to the provider.
Choice D reason: Offering the client a light snack is not a necessary action before administering digoxin, as it does not affect the absorption or effectiveness of the medication. Digoxin can be taken with or without food. Offering the client a light snack may be important for maintaining nutrition and hydration, but it is not related to digoxin therapy.

Correct Answer is C
Explanation
Choice A reason: This is incorrect because extravasation is not related to the lifetime cumulative dose limit of doxorubicin, but to the leakage of the medication from the vein into the surrounding tissue. Extravasation can cause severe tissue damage and necrosis, and should be prevented by using a central venous catheter and monitoring the infusion site.
Choice B reason: This is incorrect because red tinged urine and sweat are not related to the lifetime cumulative dose limit of doxorubicin, but to the normal excretion of the medication from the body. Red tinged urine and sweat are expected side effects of doxorubicin and do not indicate toxicity or harm.
Choice C reason: This is correct because an excess amount of doxorubicin can lead to cardiomyopathy, which is a serious and potentially fatal complication of the medication. Cardiomyopathy is a condition in which the heart muscle becomes weak and unable to pump blood effectively. The risk of cardiomyopathy increases with the cumulative lifetime dose of doxorubicin, which should not exceed 450 to 550 mg/m2.
Choice D reason: This is incorrect because myelosuppression is not related to the lifetime cumulative dose limit of doxorubicin, but to the dose-dependent effect of the medication on the bone marrow. Myelosuppression is a condition in which the production of blood cells is reduced, leading to anemia, leukopenia, and thrombocytopenia. Myelosuppression can be managed by adjusting the dose and frequency of doxorubicin and monitoring the blood counts.
Correct Answer is D
Explanation
Choice A reason: Vomiting is not a specific sign of a hemolytic reaction, as it can be caused by many other factors, such as anesthesia, infection, or medication. Vomiting may occur in other types of transfusion reactions, such as allergic or febrile reactions, but it is not indicative of hemolysis.
Choice B reason: Flushing is not a specific sign of a hemolytic reaction, as it can be caused by many other factors, such as fever, infection, or medication. Flushing may occur in other types of transfusion reactions, such as allergic or febrile reactions, but it is not indicative of hemolysis.
Choice C reason: Dyspnea is often linked with transfusion-associated circulatory overload (TACO) or transfusion-related acute lung injury (TRALI). Both of these conditions primarily impact the respiratory system, leading to difficulty breathing. Although respiratory symptoms can accompany severe reactions, dyspnea is not a key feature of a hemolytic reaction.
Choice D reason: Hypotension is a significant indicator of an acute hemolytic reaction. When the recipient’s immune system attacks the donor red blood cells, widespread inflammatory and immune responses occur, leading to vascular collapse. This can manifest as sudden low blood pressure, which is life-threatening if not recognized and treated immediately. Alongside other findings such as fever, chills, flank pain, and hemoglobinuria, hypotension is a classic hallmark of hemolysis during transfusion.
