When administering a Serotonin Antagonist it is important to monitor for

Correct Answer: C

Rationale: When administering a Serotonin Antagonist, it is important to monitor the patient's respiratory rate. Serotonin antagonists can have side effects that impact the respiratory system, such as respiratory depression. Monitoring the patient's respiratory rate can help identify any signs of respiratory distress or compromise early on, allowing for prompt intervention and prevention of any serious complications. It is crucial to closely monitor the patient's breathing when administering medications that can potentially affect the respiratory system to ensure patient safety.

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.

Correct Answer: A

Rationale: ACE (Angiotensin-Converting Enzyme) inhibitors are known to act on the Renin-Angiotensin-Aldosterone System (RAAS) by blocking the conversion of angiotensin I to the active angiotensin II. Angiotensin II is a potent vasoconstrictor and also stimulates the release of aldosterone, leading to increased blood pressure. By inhibiting ACE, ACE inhibitors help to lower blood pressure and reduce the secretion of aldosterone, thereby decreasing the overall vasoconstriction and volume expansion effects of the RAAS. Examples of ACE inhibitors include medications such as lisinopril, enalapril, and captopril.

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.

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.
