Correct Answer: C

Rationale: The correct answer is C. Drinking at least 2 liters of water daily is crucial for clients taking lithium to prevent dehydration and lithium toxicity. Lithium is a salt, so it's important for clients to maintain adequate hydration. Option A is incorrect because lithium does not interact with tyramine-containing foods. Option B is incorrect because increasing salt intake is not necessary and can actually exacerbate lithium toxicity. Option D is incorrect because avoiding caffeinated beverages is not a priority teaching point for clients taking lithium.

Correct Answer: C

Rationale: The correct first action for the nurse to take when preparing to administer packed RBCs is to check the client's identification using two identifiers. This step is crucial to ensure that the right blood is given to the right client, preventing any transfusion errors. Priming the IV tubing with dextrose 5% in water and administering the blood through a 22-gauge catheter are important steps but should come after confirming the client's identity. Ensuring the client's consent is on file is also important but is not the immediate priority when preparing to administer packed RBCs.

Correct Answer: C

Rationale: Encouraging the client to take frequent rest periods is an appropriate intervention for managing mania in a client with bipolar disorder. During a manic episode, individuals often have increased energy levels, decreased need for sleep, and may engage in high-risk behaviors. Encouraging regular rest periods can help reduce stimulation and promote relaxation, which may assist in stabilizing mood. Choices A and B are not as effective in managing manic symptoms, as they do not directly address the client's need for rest and relaxation. Choice D is inappropriate because placing the client in seclusion can increase feelings of anxiety and agitation, worsening the manic episode.

Correct Answer: D

Rationale: Administering the medication is appropriate for a stable lithium level of 0.8 mEq/L. A level of 0.8 mEq/L falls within the therapeutic range for lithium, indicating that the client is receiving an adequate dose to maintain therapeutic effects. Withholding the next dose, increasing the dosage, or discontinuing the medication would not be indicated at this lithium level as it is within the desired range for therapeutic benefit. Therefore, the correct action would be to continue administering the medication to ensure the client maintains the therapeutic level of lithium.

Correct Answer: A

Rationale: The correct intervention for a client with obsessive-compulsive disorder is to allow the client enough time to perform rituals. This helps manage anxiety and stress in individuals with OCD. Allowing time for rituals can provide a sense of control and reduce distress. Choice B, giving the client autonomy in scheduling activities, may not address the core symptoms of OCD related to rituals and compulsions. Choice C, discouraging the client from exploring irrational fears, goes against the principles of exposure therapy, which is a common treatment for OCD. Choice D, providing negative reinforcement for ritualistic behaviors, is not recommended as it can reinforce the behavior rather than help the client manage it.
