The client diagnosed with acute heart failure is prescribed an infusion of dopamine at a low dose. Which assessment parameter should the nurse use to best evaluate the effectiveness of this medication?

Urine output has increased from 30 mL to 50 mL per hour

Blood pressure decreased from 140/80 to 90/50

Heart rate has increased from 80 to 110 beats per minute

Client is awake, alert and oriented to time, place and person

Answer and Explanation

The Correct Answer is A

A.   Dopamine at low doses primarily increases renal perfusion, which can lead to improved urine output. An increase in urine output is a key indicator that the medication is effectively improving kidney function and blood flow. This is the most direct way to assess its effectiveness.
B.   A decrease in blood pressure is not an expected effect of low-dose dopamine, which should actually help improve perfusion and raise blood pressure.
C.   An increase in heart rate is more likely with higher doses of dopamine and is not an optimal indicator of the drug's effectiveness for acute heart failure.
D.   Client alertness is important but does not directly reflect the primary effects of dopamine on renal perfusion and cardiac output in acute heart failure.

Correct Answer is {"dropdown-group-1":"C","dropdown-group-2":"D","dropdown-group-3":"D"}

Explanation

Atrial fibrillation: This is a common arrhythmia where the atria quiver instead of contracting normally, leading to irregular heart rhythms.

Amiodarone- an antiarrhythmic medication may be used to control the heart rate or rhythm in atrial fibrillation.

Heparin-an anticoagulant prevent thromboembolic events, such as stroke, anticoagulants like heparin, enoxaparin, or newer agents like rivaroxaban are used.

A. Prothrombin time, fibrin level and eosinophil count B. Fibrin degradation products, lactic acid and complete blood count C. D-dimer, fibrinogen and fibrin degradation products D. Complete blood count, Complete metabolic panel and prothrombin time

Correct Answer is C

Explanation

A. This test set is incomplete for diagnosing DIC. While PT and fibrinogen are important, the eosinophil count is not a key test for DIC.
B. While fibrin degradation products are useful, lactic acid is not specific for DIC and may indicate other issues. A complete blood count is helpful but not definitive for diagnosing DIC.
C. These are key markers for DIC. An elevated D-dimer indicates clot formation and breakdown, while fibrinogen and fibrin degradation products are used to assess clotting and fibrinolysis, both of which are abnormal in DIC.
D. Complete blood count, complete metabolic panel, and prothrombin time are general tests and can give some clues, but they are not definitive for diagnosing DIC.
