Rationale: The correct instruction for a client starting Metoprolol is to avoid sudden changes in position. Metoprolol can cause orthostatic hypotension, leading to dizziness and falls if the client changes positions quickly. By advising the client to make position changes slowly, the nurse helps prevent these adverse effects and promotes safety.

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.
