A nurse is caring for a client who frequently attempts to remove his IV catheter. A family member requests that the nurse apply restraints. Which of the following responses should the nurse make?

Choice A reason: Monitoring daily weight can help detect early signs of lithium toxicity, as sudden weight gain may indicate fluid retention, which is a concern with lithium treatment. It is important for clients to monitor their weight regularly to ensure no significant fluctuations occur that could suggest adverse effects⁴.

Choice B reason: Avoiding foods with high tyramine content is not specifically related to lithium therapy. This dietary restriction is more commonly associated with monoamine oxidase inhibitors (MAOIs), a different class of psychiatric medications. Lithium does not interact with tyramine in the same way⁴.

Choice C reason: Limiting daily fluid intake is not recommended for clients taking lithium unless otherwise directed by a healthcare provider. Adequate fluid intake is essential to prevent dehydration, which can increase lithium levels and the risk of toxicity. Clients should maintain a consistent intake of fluids unless they have a condition that requires fluid restriction⁴⁵.

Choice D reason: Following a low sodium diet is not advised for clients on lithium therapy. Lithium is processed in the body similarly to sodium, so if sodium levels are too low, lithium retention may increase, leading to toxicity. Clients should maintain a consistent, adequate intake of sodium to prevent fluctuations in lithium levels⁴.

Choice A reason : This statement is misleading. While heparin does need to reach a therapeutic level to be effective, it does not directly dissolve existing clots. Heparin's primary action is to prevent the formation of new clots and the extension of existing clots by inhibiting certain factors in the coagulation cascade.

Choice B reason : While a pharmacist can provide detailed information about medications, it is the nurse's responsibility to educate and inform the client about the effects of their treatment. Therefore, this response would not be appropriate.

Choice C reason : This is the most accurate response. Heparin works by inhibiting the formation of fibrin, which is essential for clot formation. It does not have the ability to dissolve existing clots but can prevent new ones from forming and existing ones from getting larger.

Choice D reason : Oral medications such as warfarin or direct oral anticoagulants (DOACs) may be used after heparin to maintain anticoagulation; however, they also do not dissolve clots. The body's natural fibrinolytic system is responsible for breaking down clots over time.
