Answer to Question 1

ANS: A
When the drug lithium cannot be cleared and excreted by the kidney, toxicity can occur. A 1.5 toxicity lithium level is considered mild.

Answer to Question 2

ANS: B
The TCAs affect norepinephrine as well as other neurotransmitters and thus have significant cardiovascular side effects. Therefore, they are used with caution in elderly clients who may have increased risk factors for cardiac problems because of their age and other medical conditions. The remaining side effects would apply to any patient taking a TCA and are not particular to an elderly person.
