A nurse is admitting a client who has acute heart failure following myocardial infarction (MI). The nurse recognizes that which of the following prescriptions by the provider requires clarification?

Choice A reason: Monitoring serum potassium is essential in heart failure and post-MI patients, especially when diuretics are prescribed. Choice B reason: Administering isotonic saline may worsen fluid overload in acute heart failure. Fluid restriction or alternative IV fluids may be more appropriate. Choice C reason: Bumetanide is a loop diuretic used to reduce fluid overload in heart failure. This prescription is appropriate. Choice D reason: Morphine may be used to relieve chest pain and anxiety in MI, though its use is more selective today. It does not require immediate clarification unless contraindicated.
