The client is diagnosed with a benign brain tumor. Which of the following features of a benign tumor is of most concern to the nurse?

Random, rapid growth of the tumor

Cells colonizing to distant body parts

Tumor pressure against normal tissues

Emission of abnormal proteins

Answer and Explanation

The Correct Answer is C

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.

Correct Answer is B

Explanation

A. Chemical agents: Chemical agents (e.g., tobacco smoke, asbestos) are significant carcinogens but are not the most influential across all types of cancer.

B. Environmental factors: Environmental factors, including exposure to radiation, chemicals, and lifestyle choices, have a broad impact on cancer development. This is the most comprehensive factor, as it encompasses various elements that contribute to cancer risk.

C. Viruses: Certain viruses (e.g., HPV, Hepatitis B) are linked to specific cancers, but they are not the primary cause of most cancers.

D. Defective genes: Genetic mutations play a critical role in cancer development, but they are often triggered by environmental factors, making environmental factors the most significant overall.

A. A client who has recently begun treatment with propanolol (Inderal) for the treatment of social phobia. B. A woman who has been taking lorazepam (Ativan) for several months after witnessing a traumatic motor vehicle accident. C. A man whose obsessive-compulsive disorder (OCD) is being treated long-term with paroxetine (Paxil) D. A client with generalized anxiety disorder who has responded well since beginning treatment with fluoxetine (Prozac) earlier in the year.

Correct Answer is B

Explanation

A. A client who has recently begun treatment with propranolol (Inderal) for the treatment of social phobia. Propranolol, a beta-blocker, does not have a significant risk for dependence or withdrawal symptoms. It is primarily used for physical symptoms of anxiety, such as tachycardia.

B. A woman who has been taking lorazepam (Ativan) for several months after witnessing a traumatic motor vehicle accident. Lorazepam is a benzodiazepine, which has a high potential for dependence and withdrawal, especially with long-term use. This client is the most at risk for these issues.

C. A man whose obsessive-compulsive disorder (OCD) is being treated long-term with paroxetine (Paxil). While discontinuation symptoms can occur with SSRIs like paroxetine, the risk of dependence is significantly lower than with benzodiazepines.

D. A client with generalized anxiety disorder who has responded well since beginning treatment with fluoxetine (Prozac) earlier in the year. Like paroxetine, fluoxetine is an SSRI, and while discontinuation symptoms may occur, the risk of dependence is low.
