Question 1 of 5
Which of the following is an amide type of local anesthetics:
Correct Answer: B
Rationale: Articaine is an amide type of local anesthetic. Local anesthetics can be classified into two main categories: esters and amides. Articaine belongs to the amide group of local anesthetics, along with lidocaine, bupivacaine, and others. Amide local anesthetics tend to have longer duration of action and are less likely to cause allergic reactions compared to ester local anesthetics. In the given choices, Procaine, Amethocaine, and Benzocaine are ester-type local anesthetics, while Cocaine is a unique example of a local anesthetic with mixed properties.
Question 2 of 5
Antilipemic drug therapy is prescribed for a patient, and the nurse is providing instructions to the patient about the medication. Which instructions will the nurse include? (Select all that apply.)
Correct Answer: A
Rationale: A. Limit fluid intake to prevent fluid overload: Antilipemic drugs can sometimes cause fluid retention, so it is important for the patient to limit fluid intake to prevent fluid overload.
Question 3 of 5
What is the unlabeled use for Propranolol?
Correct Answer: A
Rationale: While Propranolol is commonly used to treat conditions such as hypertension and certain heart-related issues, it is also used off-label for the treatment of post-traumatic stress disorder (PTSD). Propranolol has shown efficacy in reducing the intensity of emotional memories and symptoms associated with PTSD by blocking the effects of stress hormones. It is believed to help alleviate symptoms such as anxiety and hyperarousal in individuals with PTSD. However, it is important to note that the off-label use of Propranolol for PTSD should only be done under the guidance and supervision of a healthcare professional.
Question 4 of 5
Lorraine who is on chemotherapy has a history of cardiac disease. The client is at risk for cardiac complications because:
Correct Answer: B
Rationale: Chemotherapy can cause anemia, which reduces the oxygen-carrying capacity of the blood due to decreased red blood cells or hemoglobin. For a patient with a history of cardiac disease, this is particularly concerning because the heart must work harder to deliver oxygen to tissues, potentially exacerbating cardiac conditions. Reduced white blood cells increase infection risk, but this does not directly affect cardiac function. Sodium levels and hematocrit are not the primary concerns in this context. Therefore, reduced oxygen-carrying capacity is the correct answer.
Question 5 of 5
When reviewing the mechanisms of action of diuretics, the nurse knows that which statement is true about loop diuretics?
Correct Answer: D
Rationale: Loop diuretics, such as furosemide, act on the loop of Henle in the kidney to inhibit sodium and chloride reabsorption. This leads to a rapid diuretic effect by increasing the excretion of water along with sodium, chloride, and potassium. Loop diuretics have a quick onset of action, typically within 30 minutes of administration, and can cause a significant increase in urine output within a short period of time. This makes them ideal for treating conditions that require rapid elimination of excess fluid, such as acute pulmonary edema or severe hypertension.
