Correct Answer: B

Rationale: Dopamine, when administered at a low dose, acts on beta1 receptors in the heart, leading to increased myocardial contractility. This positive inotropic effect results in improved cardiac output, which is beneficial for a client with severe heart failure. Dopamine does not typically cause lowered heart rate, decreased conduction through the AV node, or vasoconstriction of renal blood vessels at low doses.

Correct Answer: A

Rationale: Avoiding reinserting the needle into an IV catheter is crucial to minimizing the risk of catheter embolism.
