A nurse is caring for a client who experiences severe anxiety when going to work. The nurse should identify that which of the following areas of the autonomic nervous system is stimulated when the client goes to work?

Sympathetic nervous system

Limbic system

Parasympathetic nervous system

Vagus nerve

Answer and Explanation

The Correct Answer is A

A. The sympathetic nervous system is responsible for the "fight or flight" response, which is triggered during times of anxiety, stress, or fear. It increases heart rate, blood pressure, and prepares the body to respond to perceived threats, which aligns with the client's severe anxiety going to work.

B. The limbic system plays a role in emotion and memory but is not directly responsible for the physiological changes associated with anxiety.

C. The parasympathetic nervous system is responsible for "rest and digest" functions, counteracting the sympathetic nervous system’s responses during relaxation, not during anxiety.

D. The vagus nerve is part of the parasympathetic system and is not primarily responsible for the acute anxiety response.

Correct Answer is A

Explanation

A. A lithium level of 1.0 mEq/L is within the therapeutic range (0.6 to 1.2 mEq/L). The nurse should administer the morning dose of lithium as prescribed.

B. While it is important to monitor for medication adherence, there is no indication from the current lithium level that this client is refusing the medication.

C. Gastric lavage is unnecessary, as the lithium level is not elevated enough to warrant this extreme intervention.

D. Early signs of lithium toxicity typically occur with levels above 1.5 mEq/L. Since the level is 1.0 mEq/L, the nurse should proceed with administering the medication.

Correct Answer is ["2"]

Explanation

150 mg is to 1 capsule as 300 mg is to x capsules

So, 150/1 = 300/x

Cross-multiplying: 150x = 300

Dividing both sides by 150: x = 2

Therefore, the nurse should administer 2 capsules per dose.
