Clients using antianxiety drugs should be cautious when driving or performing tasks requiring mental alertness because antianxiety drugs may cause:

A. "Are you feeling worse since taking the medication?" This is an important safety question to ask, as it helps to assess whether the client’s condition has worsened since starting the medication. However, it is not the first priority when evaluating the efficacy of a newly prescribed antidepressant.

B. "How long have you been taking the medication?" This is the most important question to ask first because the effectiveness of imipramine, a tricyclic antidepressant, can take several weeks to become apparent. If the client has not been taking the medication for an adequate period, the drug may simply not have had enough time to work yet.

C. "What time of day are you taking the medication?" While the timing of the medication can affect side effects, it is less critical than knowing how long the client has been on the medication when assessing its effectiveness.

D. "What dosage of medication are you taking?" This is an important follow-up question but not the first priority. The duration of treatment is more critical to assess before considering dosage adjustments.

A. Random, rapid growth of the tumor: Benign tumors generally grow slowly and are less likely to invade nearby tissues. Rapid growth is more characteristic of malignant tumors.

B. Cells colonizing to distant body parts: Benign tumors do not metastasize to distant parts of the body; this is a feature of malignant tumors.

C. Tumor pressure against normal tissues: Even though benign tumors do not invade other tissues, they can still cause problems by pressing against surrounding normal tissues, potentially leading to significant functional issues depending on their location.

D. Emission of abnormal proteins: Abnormal protein emission is more relevant to malignancies that may cause paraneoplastic syndromes rather than benign tumors.
