Question 1 of 5
What is the Therapeutic E昀昀ects of Lithium?
Correct Answer: A
Rationale: Lithium is primarily used as a mood stabilizer in the treatment of bipolar disorder. One of the therapeutic effects of lithium is its ability to prevent or decrease the incidence of acute manic episodes in individuals with bipolar disorder. By regulating neurotransmitter levels and affecting intracellular signaling pathways, lithium helps to stabilize mood and prevent the extreme highs of mania. It does not have a direct effect on blood glucose maintenance, control of hyperglycemia, or seizure activity, which are unrelated to its primary mechanism of action in managing mood disorders.
Question 2 of 5
The nurse assesses the client might be experiencing toxicity from colchicine. Which statement by the client would most likely confirm the nurse's suspicion?
Correct Answer: B
Rationale: Colchicine toxicity causes GI distress-nausea, vomiting, pain-per overdose data, a hallmark sign. Joint pain is gout, not toxicity. Vision/taste changes or cramps aren't linked-GI rules. This confirms suspicion, per assessment.
Question 3 of 5
A patient reports having adverse effects with nicotinic acid (niacin). The nurse can suggest performing which action to minimize these undesirable effects?
Correct Answer: D
Rationale: Taking an aspirin tablet 30 minutes before taking nicotinic acid (niacin) can help minimize the undesirable effects such as flushing, itching, and rash. Aspirin helps to reduce these side effects by blocking the prostaglandin synthesis that mediates the flushing response associated with niacin therapy. This intervention can improve medication adherence and tolerance in patients who experience discomfort with nicotinic acid therapy.
Question 4 of 5
A client is prescribed with Pentamidine (Pentam) IV for the treatment of Pneumocystis carinii
Correct Answer: D
Rationale: A sudden increase in temperature (fever) to 101.5°F in a client receiving Pentamidine IV for Pneumocystis carinii pneumonia would most likely indicate the client has developed another infection. This is because Pentamidine IV is an antibiotic used to treat Pneumocystis carinii pneumonia, and a new fever during treatment would suggest a new or persistent infection causing the elevated temperature. It is important for the nurse to assess the client further and consider additional diagnostic tests or treatments for the new infection while continuing to monitor and manage the initial condition for which Pentamidine was prescribed.
Question 5 of 5
A patient has had recent mechanical heart valve surgery and is receiving anticoagulant therapy. While monitoring the patient™s laboratory work, the nurse interprets that the patient™s international normalized ratio (INR) level of 3 indicates that:
Correct Answer: B
Rationale: An international normalized ratio (INR) level of 3 is within the recommended therapeutic range for patients on anticoagulant therapy, particularly those with mechanical heart valve surgery. The target INR range for patients with mechanical heart valves is typically between 2.5 to 3.5. An INR of 3 indicates that the patient™s warfarin dose is at the appropriate therapeutic levels to prevent blood clots while minimizing the risk of bleeding complications. It is essential to closely monitor and adjust the patient's warfarin dose based on their INR levels to maintain a balance between preventing clot formation and avoiding excessive bleeding.
