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) Take this medication with food:
Captopril is an ACE inhibitor, known to work best on an empty stomach. Food can reduce its absorption, impacting its effectiveness. Thus, while clients can take captopril with or without food, it's generally recommended to take it on an empty stomach for optimal results.

B) Monitor for a cough:
Captopril, an ACE inhibitor, commonly induces a persistent, dry cough due to the accumulation of bradykinin. This side effect can be bothersome and may necessitate discontinuation of the medication. Therefore, patients should be vigilant for the onset of a cough and promptly report it to their healthcare provider.

C) Avoid bananas:
Although captopril can occasionally lead to hyperkalemia, advising patients to avoid bananas specifically may not be necessary. While bananas are potassium-rich, restricting them alone might not significantly impact potassium levels. However, patients should be educated on monitoring potassium intake and informed of potential dietary modifications if hyperkalemia occurs.

D) Hold medication for heart rate less than 100/min:
Captopril is not known to directly affect heart rate. This instruction may be more applicable to medications like beta-blockers, which can lower heart rate as part of their mechanism of action. Therefore, holding captopril for heart rates below 100/min may not be clinically indicated.
