Question 1 of 5
A patient who has been taking a benzodiazepine as a sleep aid for several months wishes to stop taking the medication. The nurse will suggest that the patient taper the dose gradually to avoid which effect?
Correct Answer: D
Rationale: When a patient has been taking a benzodiazepine for an extended period, abruptly stopping the medication can lead to withdrawal symptoms. These symptoms may include anxiety, irritability, agitation, insomnia, tremors, sweating, and in severe cases, seizures. To avoid these withdrawal effects, the nurse will recommend tapering the dose gradually under medical supervision. This approach allows the body to adjust slowly and reduces the likelihood of experiencing withdrawal symptoms. It is essential to follow a tapering schedule under the guidance of a healthcare provider to ensure a smooth transition off the medication and minimize the risk of withdrawal.
Question 2 of 5
A prenatal patient tells the nurse that she is not taking vitamins because she heard that vitamins may cause damage to the fetus if she becomes pregnant. What is the nurse's best response?
Correct Answer: C
Rationale: While vitamins are generally beneficial during pregnancy, excessive doses (megadoses) can be harmful, especially in the first trimester. The nurse should emphasize the importance of taking vitamins at recommended levels and avoiding excessive supplementation. Taking extra vitamins (B) is not advised, and doses above the RDA (D) should be avoided unless prescribed.
Question 3 of 5
Superficial bladder cancer can be treated by direct instillation of the antineoplastic antibiotic agent mitomycin (Mutamycin). This process is termed:
Correct Answer: B
Rationale: Intravesical administration involves the direct instillation of medication into the bladder, which is a common method for treating superficial bladder cancer. This approach allows high concentrations of the drug, such as mitomycin, to come into direct contact with the cancerous cells lining the bladder, minimizing systemic side effects. Intraventricular and intrathecal administrations are used for delivering drugs to the brain and spinal cord, respectively, while intravascular administration refers to intravenous delivery. Intravesical administration is specifically designed for bladder conditions, making it the correct answer.
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
Which of the following drugs is most effective in converting a patient with atrial fibrillation into sinus rhythm?
Correct Answer: B
Rationale: Converting atrial fibrillation (AF) to sinus rhythm requires cardioversion or antiarrhythmics. Digoxin controls rate, not rhythm, ineffective for conversion. Atenolol, a beta-blocker, and diltiazem, a calcium channel blocker, manage rate, not rhythm restoration. Lidocaine treats ventricular arrhythmias. Amiodarone, a class III antiarrhythmic, prolongs repolarization, effectively converting AF to sinus rhythm, especially in acute settings, outperforming others. Its broad-spectrum action is key in AF management, balancing efficacy and safety.
