Question 1 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 2 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.
Question 3 of 5
the antidote for Warfarin is?
Correct Answer: B
Rationale: Warfarin is an oral anticoagulant that works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver. Therefore, the antidote for Warfarin overdose or to reverse its effects is vitamin K. Vitamin K helps in replenishing the depleted vitamin K-dependent clotting factors, allowing the blood to clot normally again. Administering vitamin K helps in reversing the anticoagulant effects of Warfarin, preventing excessive bleeding or hemorrhage.
Question 4 of 5
A neighbor tells nurse Maureen he has to have surgery and is reluctant to have any blood product transfusions because of a fear of contracting an infection. He asks the nurse what are his options. The nurse teaches the person that the safest blood product is:
Correct Answer: C
Rationale: An autologous blood product is the safest option for the neighbor who is reluctant to have blood transfusions due to a fear of contracting an infection. Autologous blood is blood that is donated by the patient themselves prior to surgery. This type of blood product eliminates the risk of transmitting infections from other donors, as the blood comes from the patient's own body. It is considered the safest option for those concerned about infection transmission during blood transfusions.
Question 5 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.
