A nurse is teaching a patient about a medication that alters sympathetic nervous system functions. To evaluate understanding, the nurse asks the patient to describe which functions the sympathetic nervous system regulates. Which answer indicates the need for further teaching?

Choice A Reason:

Increased neuromuscular excitability is not typically associated with respiratory acidosis. Instead, respiratory acidosis can lead to symptoms such as confusion, fatigue, and shortness of breath due to the buildup of carbon dioxide in the blood. Neuromuscular excitability is more commonly associated with conditions like hypocalcemia.

Choice B Reason:

This is the correct answer. Respiratory acidosis occurs when the lungs cannot remove enough carbon dioxide (CO2) from the body, leading to an accumulation of CO2 in the blood. This increase in CO2 results in the formation of carbonic acid, which lowers the pH of the blood. The elevated levels of carbonic acid are a hallmark of respiratory acidosis.

Choice C Reason:

Increased pH is not associated with respiratory acidosis. In fact, respiratory acidosis is characterized by a decrease in blood pH due to the accumulation of carbon dioxide and the subsequent increase in carbonic acid. Therefore, this choice is incorrect.

Choice D Reason:

Hypokalemia, or low potassium levels, is not typically associated with respiratory acidosis. Instead, respiratory acidosis can sometimes lead to hyperkalemia (high potassium levels) due to the shift of potassium out of cells in response to the acidotic state. Therefore, this choice is incorrect.

Choice A Reason:

An idiosyncratic effect is an unusual or unexpected reaction to a drug that is not related to the dose and is not a common side effect. These reactions are often due to genetic differences in metabolism or immune response. In this case, shortness of breath is a known reaction for some patients taking the drug, so it is not considered idiosyncratic.

Choice B Reason:

A teratogenic effect refers to a drug’s potential to cause developmental abnormalities in a fetus when taken by a pregnant woman. Since the patient is experiencing shortness of breath, which is a known reaction to the drug, this choice is not relevant to the situation.

Choice C Reason:

This is the correct answer. A side effect is a secondary, typically undesirable effect of a drug or medical treatment. Since the nurse found that shortness of breath is a known reaction for some patients taking the drug, it is classified as a side effect. The nurse should report this to the provider to ensure proper management and monitoring.

Choice D Reason:

The symptom of shortness of breath is related to the medication administration, as confirmed by the drug administration manual. Therefore, this choice is incorrect. The nurse must report the side effect to the provider for appropriate action.
