Question 1 of 5
The most potent of ester type of Local Anesthesia:
Correct Answer: B
Rationale: Articaine is considered the most potent ester type of local anesthetic. It is known for its high efficacy in providing profound anesthesia due to its unique chemical structure that enhances its ability to penetrate tissues effectively. Articaine also has a rapid onset of action and a relatively long duration of action compared to other ester local anesthetics. These characteristics make it a popular choice for various dental and medical procedures where deep and long-lasting anesthesia is required.
Question 2 of 5
The nurse is caring for a patient who is receiving warfarin (Coumadin) and notes bruising and petechiae on the patient's extremities. The nurse will request an order for which laboratory test?
Correct Answer: B
Rationale: Bruising and petechiae on a patient's extremities are signs of potential thrombocytopenia, which is a decrease in platelet count. Warfarin (Coumadin) is an anticoagulant that works by interfering with the body's ability to use vitamin K to form blood clots. While the International normalized ratio (INR) is often used to monitor the effectiveness of warfarin therapy, and PTT and aPTT may also be relevant in certain cases, the presence of bruising and petechiae suggest a potential issue with platelet levels. Therefore, checking the patient's platelet level with a laboratory test is appropriate in this situation to assess for thrombocytopenia.
Question 3 of 5
A busy patient with many responsibilities is to have a medication ordered to treat her hypertension. To increase compliance with drug therapy, what drug would be a good choice for this patient?
Correct Answer: D
Rationale: Metoprolol would be the best choice because it has an extended-release form that only needs to be taken once a day, which should increase patient compliance. Acebutolol, atenolol, and bisoprolol do not come in extended-release forms. The nurse should consider the patient’s lifestyle and preferences when selecting antihypertensive medications to improve adherence.

Question 5 of 5
The most common dose-limiting toxicity of chemotherapy is:
Correct Answer: C
Rationale: Myelosuppression, the suppression of bone marrow activity, is the most common dose-limiting toxicity of chemotherapy. It leads to reduced production of blood cells, including white blood cells, red blood cells, and platelets, increasing the risk of infections, anemia, and bleeding. While nausea, vomiting, and mucositis are significant side effects, they can often be managed with supportive care. Myelosuppression, however, can be life-threatening and frequently requires dose adjustments or delays in treatment. Bloody stools are less common and typically not the primary dose-limiting factor.
