Question 1 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 2 of 5
A patient has been taking digoxin at home but took an accidental overdose and has developed toxicity. The patient has been admitted to the telemetry unit, where the physician has ordered
Correct Answer: D
Rationale: The correct response is E, This drug is an antidote to digoxin and will help to lower the blood levels. In cases of digoxin toxicity, the antidote is digoxin immune fab (Digibind), which helps to lower the blood levels of digoxin by binding to it and facilitating its removal from the body. This response provides the patient with important information about the purpose of the medication being ordered by the physician. It is crucial that the patient understands the rationale behind the treatment to manage the overdose effectively.
Question 3 of 5
A 48-year-old woman with 2-year history of rheumatoid arthritis has not had sufficient relief with methotrexate alone. Her physician prescribes etanercept to help control her symptoms. How does etanercept work?
Correct Answer: D
Rationale: Etanercept, a TNF-α inhibitor, works by inhibiting TNF-α signaling , reducing RA inflammation. Substance P depletion , COX inhibition , and chemotaxis inhibition are unrelated. Arachidonic acid prevention (E) isn't its role. This targets a key RA cytokine.
Question 4 of 5
what is the route of INSULIN GLARGINE:
Correct Answer: A
Rationale: Insulin glargine is a type of long-acting insulin that is given via subcutaneous injection. Subcutaneous administration involves injecting the medication into the fatty tissue layer just beneath the skin. This route allows for slow and consistent absorption of the insulin into the bloodstream, providing a prolonged effect on lowering blood sugar levels. Insulin cannot be taken orally because it would be broken down by the digestive system before it could be effective. Intravenous (IV) administration is also not appropriate for insulin glargine because it is meant to have a slow, sustained release in the body, which cannot be achieved with IV administration. Sublingual administration, where a medication is placed under the tongue for absorption, is not suitable for insulin as it requires specific pathways for absorption that are not present under the tongue.
Question 5 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.
