Question 1 of 5
What classification of drug is Penicillin?
Correct Answer: C
Rationale: Penicillin is classified as an antibiotic drug, specifically an antibacterial agent. It is used to treat various bacterial infections by inhibiting the growth of bacteria or killing them directly. Therefore, it is not categorized as an antiarrhythmic, anticonvulsant, or mood stabilizer. Instead, Penicillin falls under the classification of drugs that are effective against bacterial infections, making it an "anti-ineffective" drug.
Question 2 of 5
Hemostatic agents that arrest the flow of blood from small vessels by precipitating the tissue proteins in the immediate area:
Correct Answer: B
Rationale: Styptics and astringents are hemostatic agents that work by precipitating tissue proteins in the immediate area of a small vessel to stop bleeding. Styptics such as alum, silver nitrate, and ferric subsulfate directly induce coagulation at the site of bleeding, forming a protective scab to stop the flow of blood. Astringents like tannic acid work by tightening the tissue proteins around the blood vessel to create a seal and halt bleeding. These agents are commonly used in the management of minor cuts and wounds to promote hemostasis.
Question 3 of 5
In Fried's rule of dosage calculation, it is the number of months a child has reached an age when an adult dose can be tolerated>
Correct Answer: C
Rationale: In Fried's rule for dosage calculation, the formula is to divide the child's age in months by 150 to find the fraction of adult dose that can be tolerated. Generally, a child is considered to tolerate an adult dose when they have reached 12 months of age. This is based on the assumption that a 12-month-old child can typically tolerate a dose similar to that of an adult. Therefore, the correct answer is 12 months, which is option C.
Question 4 of 5
A patient taking isoniazid is worried about the negative effects of the drug. The nurse provides information knowing that which is an adverse effect of the drug?
Correct Answer: B
Rationale: Isoniazid is associated with hepatotoxicity, which can range from asymptomatic elevation of liver enzymes to severe hepatitis. Patients should be monitored for symptoms such as fatigue, nausea, and jaundice. Ototoxicity and nephrotoxicity are not common adverse effects of isoniazid. Optic neuritis is a rare side effect of ethambutol, another antitubercular drug, not isoniazid.
Question 5 of 5
Which nonselective alpha-adrenergic blocking agent is still used?
Correct Answer: D
Rationale: Of the nonselective alpha-adrenergic blocking agents, only phentolamine is still used today. Metoprolol is a beta1-selective adrenergic blocking agent. Timolol and propranolol are nonselective beta-adrenergic blocking agents. The nurse should understand the indications for phentolamine to ensure safe and effective administration.
