When caring for a client with diabetes insipidus who is receiving antidiuretic hormone intranasally, which serum lab test is most important for the nurse to monitor?

Platelets

Glucose

Osmolality

Calcium

Answer and Explanation

The Correct Answer is C

Diabetes insipidus is a condition in which the kidneys are unable to conserve water, leading to excessive thirst and urination. It is treated with antidiuretic hormone (ADH), which helps the kidneys retain water and reduce urine output. When caring for a client with diabetes insipidus who is receiving ADH intranasally, it is important for the nurse to monitor the client’s serum osmolality.

Osmolality is a measure of the concentration of particles in a solution and can provide information about the client’s hydration status.

Monitoring serum osmolality can help determine if the ADH therapy is eﬀective in managing the client’s diabetes insipidus.

Correct Answer is C

Explanation

Continuous rubbing of the back of the neck can be a side eﬀect of antipsychotic medication, known as acute dystonia. Benztropine is an anticholinergic medication that can eﬀectively treat acute dystonia. Therefore, the nurse should give a PRN prescription for benztropine to relieve the client's discomfort. Options a, b, and d do not address the underlying issue of acute dystonia and are not the best interventions for this particular situation.

A. Eliminate use of nonsteroidal anti-inﬂammatory drugs. (NSAIDs) B. Avoid consuming all foods that contain Iodine. C. Notify healthcare provider prior to dental procedures. D. Monitor blood glucose levels daily.

Correct Answer is A

Explanation

Lithium carbonate is a mood stabilizer commonly used to treat bipolar disorder. However, it has a narrow therapeutic index and requires careful monitoring of serum levels to avoid toxicity. One of the major concerns with lithium therapy is the potential for drug interactions and toxicity. NSAIDs such as ibuprofen and naproxen can increase lithium levels by reducing its excretion and can lead to lithium toxicity. Therefore, it is essential to instruct the client to eliminate the use of NSAIDs while taking lithium.

Option b) Avoid consuming all foods that contain iodine is incorrect because iodine is not contraindicated with lithium. However, excessive iodine intake can interfere with thyroid function, which can exacerbate mood instability.

Option c) Notify healthcare provider prior to dental procedures is not specific to lithium therapy and is a general precaution that patients with bipolar disorder should follow before any medical or dental procedures.

Option d) Monitor blood glucose levels daily is also not directly related to lithium therapy. While lithium can cause diabetes insipidus, which can lead to excessive thirst and urination, it does not typically aﬀect blood glucose levels.
