Correct Answer is A

Explanation

Choice A rationale:

Withholding the dose if having a fine hand tremor is not recommended. Hand tremors are a common side effect of lithium, but they can be managed by adjusting the dose.

Choice B rationale:

Avoiding foods with a high tyramine content is not necessary for lithium users. This dietary restriction is typically associated with certain antidepressants, not lithium.

Choice C rationale:

Limiting daily fluid intake is incorrect. Lithium can cause increased thirst and urination, so it’s important to maintain adequate hydration.

Choice D rationale:

Following a low-sodium diet is not advised. Both salt and fluid can affect the levels of lithium in your blood, so it’s important to consume a steady amount every day.

So, the correct answer is, none of the above.

Correct Answer is ["B","C","D"]

Explanation

Choice A rationale:

Blistering around the insertion site is not a common sign of phlebitis. It could indicate a more severe complication like extravasation or infiltration.

Choice C rationale:

Erythema at the insertion site is another common sign of phlebitis. It indicates inflammation.

Choice D rationale:

Warmth at the insertion site is also a common sign of phlebitis. It is caused by increased blood flow to the area due to inflammation. So, the correct answers are B, C, and D.
