Question 1 of 5
What is the therapeutic use for Lithium?
Correct Answer: B
Rationale: Lithium is commonly used as a mood stabilizer in the treatment of bipolar disorder. It is particularly effective in reducing the frequency and severity of manic episodes. By stabilizing mood and decreasing manic symptoms, lithium helps to prevent the occurrence of acute manic episodes in individuals with bipolar disorder. It does not specifically target blood pressure, seizure activity, or urinary output.
Question 2 of 5
The nurse administers a vaccine to a child. What is the best understanding of the nurse as it relates to the manufacture of this vaccine?
Correct Answer: B
Rationale: Vaccines are typically produced using animal cells (e.g., eggs) or microorganisms (e.g., bacteria, yeast) to grow antigens, mimicking natural pathogen processes for immunity. Plant extracts aren't standard-most use biological systems. Combination products are rare; animal/microbial methods dominate. Lab synthesis applies to small molecules, not complex vaccines. This understanding reflects standard bioprocessing, ensuring effective immune response.
Question 3 of 5
Component added to local anesthetic solution to reduce the systemic uptake of the anesthetic agent:
Correct Answer: A
Rationale: One of the most common components added to local anesthetic solutions to reduce the systemic uptake of the anesthetic agent is a vasoconstrictor. Vasoconstrictors, such as epinephrine, work by causing constriction of blood vessels at the site of injection. This constriction reduces blood flow to the area, which in turn reduces the systemic absorption of the anesthetic agent. By limiting systemic absorption, vasoconstrictors can help to prolong the duration of local anesthesia and minimize potential side effects associated with high systemic levels of the anesthetic agent, such as cardiovascular effects.
Question 4 of 5
A 79-year-old patient is taking a diuretic for treatment of hypertension. This patient is very
Correct Answer: A
Rationale: The nurse will know that it is important to teach the patient to take extra precautions when standing up because of the potential risk of orthostatic hypotension and falls while taking a diuretic for hypertension. Orthostatic hypotension is a common side effect of diuretics, which can lead to dizziness or lightheadedness when changing positions, particularly when standing up quickly. This can increase the risk of falls and injury, especially in elderly patients like this 79-year-old individual. Therefore, the teaching point about taking extra precautions while standing up is crucial for the safety and well-being of the patient.
Question 5 of 5
During a blood transfusion, the patient begins to have chills and back pain. What is the nurse™s priority action?
Correct Answer: D
Rationale: The nurse's priority action would be to discontinue the infusion immediately and notify the prescriber. The patient developing chills and back pain during a blood transfusion may be signs of a transfusion reaction, possibly indicating an incompatibility or adverse reaction to the blood product. It is crucial to stop the transfusion to prevent further complications and to notify the prescriber immediately so that appropriate interventions can be initiated promptly. Observing for other symptoms and slowing the infusion rate are secondary actions compared to discontinuing the infusion and informing the prescriber in this situation. Telling the patient that these symptoms are a normal reaction to the blood product is incorrect as the symptoms could indicate a serious issue that needs to be addressed promptly.
