A client prescribed lithium carbonate 300 mg twice daily 3 months ago comes to the Emergency Department with nausea, diarrhea, muscle weakness, and coarse tremors. They notified the provider that they have had flu like symptoms and have not been able to eat or drink. The nurse suspects the client is exhibiting signs of:

toxicity from the lithium carbonate.

developing a tolerance to the lithium carbonate.

stopping their prescribed lithium carbonate.

consuming foods high in tyramine while taking lithium carbonate.

Answer and Explanation

The Correct Answer is A

A. Lithium carbonate is a medication commonly used to treat bipolar disorder. Symptoms of lithium toxicity can include nausea, vomiting, diarrhea, muscle weakness, tremors, and flu-like symptoms. If a client is experiencing these symptoms after taking lithium carbonate, it could indicate lithium toxicity
B. Lithium is a mood stabilizer, and tolerance, in the sense of needing increasing doses to achieve the same effect, is not commonly observed.
C. Suddenly stopping lithium carbonate can lead to withdrawal symptoms, but the symptoms described— nausea, diarrhea, muscle weakness, and tremors—are more indicative of toxicity rather than withdrawal.
D. Tyramine is a compound found in certain foods and beverages, and interactions between tyramine-rich foods and certain medications, such as monoamine oxidase inhibitors (MAOIs), can lead to hypertensive crises. However, lithium carbonate is not known to have interactions with tyramine-rich foods.

Correct Answer is B

Explanation

B. Airborne precautions are used for diseases that can be transmitted through tiny respiratory droplets that remain in the air for extended periods. Examples include tuberculosis and measles. Given the symptom of coughing up blood and the possibility of an infectious respiratory disease, initiating airborne precautions could be warranted.
A. Droplet precautions are typically implemented for diseases that spread through respiratory droplets, such as influenza or pertussis. However, coughing up blood suggests a more serious condition that may not be adequately addressed by droplet precautions alone.
C. Positive pressure rooms are typically used in healthcare settings to prevent outside air from entering the room, thus reducing the risk of airborne contaminants. While this measure can be beneficial for certain conditions, such as those requiring airborne precautions, it may not be the priority intervention.
D. Neutropenic precautions are implemented for patients with compromised immune systems, particularly those with low white blood cell counts (neutropenia). While this precaution is important for protecting immunocompromised patients from infections, it may not be the priority intervention.

A. fluphenazine. B. methylphenidate. C. diazepam. D. haloperidol.

Correct Answer is B

Explanation

B. Methylphenidate is a central nervous system stimulant commonly used in the treatment of ADHD. It works by increasing the levels of certain neurotransmitters in the brain, which helps improve attention, focus, and impulse control in individuals with ADHD. Teaching the family about methylphenidate would be appropriate as it is one of the most commonly prescribed medications for ADHD.
A. Fluphenazine is an antipsychotic medication primarily used to treat psychotic disorders such as schizophrenia and bipolar disorder. It is not typically used as a first-line treatment for ADHD
C. Diazepam is a benzodiazepine medication primarily used to treat anxiety disorders, muscle spasms, and seizures. It is not indicated for the treatment of ADHD.
D. Haloperidol is an antipsychotic medication primarily used to treat psychotic disorders and severe behavioral disturbances. It is not a first-line treatment for ADHD.
