A nurse caring for a client”who has hypertension and asks the nurse about a prescription for propranolol. The nurse should inform the client that this medication is contraindicated in clients who have a history of which of the following conditions?

A) Eustress:
Eustress refers to positive or beneficial stress that motivates individuals to achieve goals, enhance performance, and promote growth. While eustress plays a role in overall well-being, it does not specifically describe the balance between the sympathetic and parasympathetic nervous systems.

B) Homeostasis:
This is the correct answer. Homeostasis refers to the body's ability to maintain stable internal conditions despite external changes. It involves a dynamic equilibrium that allows various physiological processes to function optimally. The balance between the sympathetic and parasympathetic nervous systems contributes to maintaining homeostasis by regulating functions such as heart rate, blood pressure, digestion, and respiratory rate.

C) Power:
Power typically refers to the ability to exert influence or control over others or situations. While power dynamics may play a role in various aspects of human interaction, it is not specifically related to the balance between the sympathetic and parasympathetic nervous systems.

D) Strength:
Strength refers to the physical or mental capacity to withstand stress or exertion. While strength is important for overall health and resilience, it does not specifically describe the balance between the sympathetic and parasympathetic nervous systems.

A) Bicarbonate:
While bicarbonate levels may be relevant in some cases, they are not typically a primary consideration before administering furosemide. Furosemide primarily affects electrolyte balance, particularly potassium and sodium, rather than bicarbonate levels.

B) Potassium:
This is the correct answer. Before administering furosemide, it is essential to review the client's potassium levels because furosemide is a loop diuretic that can lead to potassium depletion. Monitoring potassium levels helps prevent hypokalemia, which can lead to cardiac dysrhythmias and other complications, especially in clients with heart failure.

C) Phosphate:
Phosphate levels are not typically a primary concern before administering furosemide. Furosemide primarily affects sodium and potassium levels rather than phosphate levels.

D) Carbon dioxide:
Carbon dioxide levels are not typically a primary consideration before administering furosemide. Furosemide primarily affects electrolyte balance rather than carbon dioxide levels.
