A nurse is educating a client about the sympathetic nervous system. Which of the following statements is correct?
The sympathetic nervous system is responsible for "fight or flight."
The sympathetic nervous system helps us to rest and digest.
The sympathetic nervous system Includes the cranial nerves.
The sympathetic nervous system can lower blood pressure.
The Correct Answer is A
A) The sympathetic nervous system is responsible for "fight or flight":
This is the correct answer. The sympathetic nervous system is responsible for the "fight or flight" response, which prepares the body to react to perceived threats or stressors by increasing heart rate, dilating pupils, redistributing blood flow, and releasing stress hormones such as adrenaline and noradrenaline.
B) The sympathetic nervous system helps us to rest and digest:
This statement is incorrect. The parasympathetic nervous system is responsible for the "rest and digest" response, which promotes relaxation, digestion, and conservation of energy.
C) The sympathetic nervous system includes the cranial nerves:
This statement is incorrect. The sympathetic nervous system is primarily associated with the thoracolumbar region of the spinal cord and does not include the cranial nerves, which are primarily associated with the parasympathetic nervous system.
D) The sympathetic nervous system can lower blood pressure:
This statement is incorrect. The sympathetic nervous system typically increases blood pressure as part of the "fight or flight" response by increasing heart rate and constricting blood vessels to redirect blood flow to vital organs and muscles.

Correct Answer is B
Explanation
A) Weight and caloric intake:
While weight and caloric intake are important aspects of overall health assessment, they are not directly related to the administration of beta-adrenergic blocking agents. These medications primarily affect cardiovascular function, so assessing pulse and blood pressure is more pertinent.
B) Pulse and blood pressure:
This is the correct answer. Before administering beta-adrenergic blocking agents, it is essential to assess the client's pulse rate and blood pressure. Beta blockers work by blocking the effects of adrenaline, leading to a decrease in heart rate and blood pressure. Monitoring these vital signs helps determine the appropriateness of administering the medication and allows for adjustments based on the client's current cardiovascular status.
C) Serum sodium level:
Assessing serum sodium level is not typically necessary before administering beta-adrenergic blocking agents. While electrolyte imbalances can occur as a result of certain medications or health conditions, beta blockers do not directly affect serum sodium levels.
D) Serum albumin level:
Assessing serum albumin level is not specifically indicated before administering beta-adrenergic blocking agents. Serum albumin levels may be assessed in clients with certain conditions such as liver or kidney disease, but it is not a routine assessment before administering beta blockers.
Correct Answer is B
Explanation
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.
