Question 1 of 5
The following are commonly associated with phlebitis when given via the intravenous route:
Correct Answer: A
Rationale: Potassium chloride is highly irritant to veins and often leads to inflammation (phlebitis) when administered intravenously.
Question 2 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 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
The following inhibits cell wall synthesis, except:
Correct Answer: D
Rationale: Nystatin is an antifungal medication that works by disrupting fungal cell membrane function, specifically targeting ergosterol and causing the formation of pores in the cell membrane, leading to cell death in fungi. It does not inhibit cell wall synthesis, unlike the other options listed.
Question 5 of 5
Which of the following pharmacologic classifications does the drug propranolol fall under?
Correct Answer: A
Rationale: Propranolol belongs to the pharmacologic classification of Beta Blockers. Beta blockers work by blocking the action of adrenaline and other stress hormones, specifically by blocking beta receptors. Propranolol, in particular, is a non-selective beta blocker that is commonly used to treat conditions such as hypertension, angina, and arrhythmias. It is also used off-label for anxiety and migraine prevention.
