A patient diagnosed with bipolar disorder is prescribed lithium carbonate. Which laboratory result should prompt the nurse to hold the medication and notify the healthcare provider?

Potassium 4.2 mEq/L

Sodium 136 mEq/L

Calcium 9.0 mg/dL

Creatinine 2.1 mg/dL

Answer and Explanation

The Correct Answer is D

A. Potassium 4.2 mEq/L is within the normal range (3.5–5.0 mEq/L).

B. Sodium 136 mEq/L is slightly low but does not warrant withholding lithium. However, sodium levels should be monitored regularly as low sodium increases the risk of lithium toxicity.

C. A calcium level of 9.0 mg/dL is within the normal range (8.5–10.2 mg/dL).

D. An elevated creatinine level (2.1 mg/dL) indicates possible renal dysfunction, which is a concern for lithium use. Lithium is excreted by the kidneys, and impaired renal function increases the risk of lithium toxicity.

Correct Answer is A

Explanation

A. Impulsivity, a hallmark of mania, can increase the risk of suicidal behavior, particularly if the client makes rash decisions without regard for consequences.

B. Identifying with problems expressed by others does not necessarily indicate suicidal thoughts, but rather may show empathy or a desire for connection.

C. Wanting to go home may indicate longing for normalcy, but by itself, it does not suggest imminent risk for suicide.

D. Playing basketball can indicate engagement with others and an improvement in mood or functioning, rather than an increased suicide risk.

A. Document the size and location of the cuts. B. Inspect the cuts for debris. C. Administer a tetanus antitoxin. D. Implement the client's behavioral modification plan.

Correct Answer is B

Explanation

A. Documenting the size and location is important for medical records, but it is secondary to providing immediate care for the wounds.

B. The first action is to inspect the cuts for any debris to ensure proper wound care. Cleaning the wounds and assessing their severity is necessary to prevent infection.

C. Administering a tetanus antitoxin is not the first step unless the cuts show signs of contamination or the patient is at risk of tetanus.

D. Implementing a behavioral modification plan is important for addressing self-harm behaviors, but the immediate priority is to assess and treat the cuts to prevent infection.
