Question 1 of 5
The most potent of ester type of Local Anesthesia:
Correct Answer: B
Rationale: Articaine is considered the most potent ester type of local anesthetic. It is known for its high efficacy in providing profound anesthesia due to its unique chemical structure that enhances its ability to penetrate tissues effectively. Articaine also has a rapid onset of action and a relatively long duration of action compared to other ester local anesthetics. These characteristics make it a popular choice for various dental and medical procedures where deep and long-lasting anesthesia is required.

Question 3 of 5
The nurse is preparing for a community education program on hypertension. Which of these parameters determine the regulation of arterial blood pressure?
Correct Answer: A
Rationale: The regulation of arterial blood pressure is primarily determined by two main parameters: cardiac output and systemic vascular resistance.
Question 4 of 5
The patient receives antibiotics for a serious infection. The patient asks the nurse, 'Why don't you just give me more of that drug to cure this infection faster?' What is the best response by the nurse?
Correct Answer: D
Rationale: Antibiotics have a maximum dose beyond which efficacy plateaus-more risks toxicity (e.g., ototoxicity), not faster cure, a pharmacodynamic limit. Checking with the doctor delays a clear answer. Interactions aren't the sole issue-toxicity is. Time-based increase lacks basis. Maximum dose explains efficacy ceiling, educating safely.
Question 5 of 5
Bactericidal action are elicited by the following, except:
Correct Answer: C
Rationale: Nystatin is an antifungal medication used to treat fungal infections caused by yeast. It works by binding to ergosterol, a component of fungal cell membranes, causing them to become porous and leaky, ultimately leading to the death of the fungus. Nystatin does not have bactericidal action because it specifically targets fungal cells and is not effective against bacteria.
