Question 1 of 5
In developing a plan of care for the patient, the nurse understands that the order for pegfilgrastim was prescribed for which reason?
Correct Answer: D
Rationale: Pegfilgrastim is a long-acting form of filgrastim, modified with polyethylene glycol (pegylated) to prolong its activity. It is administered once per chemotherapy cycle to stimulate white blood cell production and reduce the risk of neutropenia. Unlike filgrastim, which requires daily injections, pegfilgrastim's extended half-life allows for less frequent dosing. The nurse should educate the patient about the dosing schedule and monitor for side effects, such as bone pain.

Question 3 of 5
What is an expected outcome for Lithium
Correct Answer: D
Rationale: Lithium is commonly used in the treatment of bipolar disorder. One of the expected outcomes of lithium treatment is a decreased incidence of acute manic episodes. Lithium helps stabilize mood and reduce the frequency and severity of manic episodes in patients with bipolar disorder. It is considered one of the first-line treatments for managing symptoms of mania in bipolar disorder. While lithium has various physiological effects in the body, its primary use in mental health is to manage mood symptoms associated with bipolar disorder, particularly the manic phase.
Therefore, the expected outcome of lithium treatment is a decrease in the incidence of acute manic episodes.
