Question 1 of 5
This serves as an indication of time required for a dosing regimen to achieve a steady state concentration of drug in blood
Correct Answer: B
Rationale: The half-life is the time required for the concentration of a drug in the blood to decrease by 50%. It serves as an indication of the time required for a dosing regimen to achieve a steady state concentration of the drug in the blood. Understanding the half-life of a drug is crucial for determining the dosing interval needed to maintain therapeutic levels. Long half-lives require less frequent dosing to reach steady state, while short half-lives demand more frequent dosing to achieve the desired drug concentration in the blood over time.
Question 2 of 5
The nurse is reviewing factors that influence pharmacokinetics in the neonatal patient. Which factor puts the neonatal patient at risk with regard to drug therapy?
Correct Answer: A
Rationale: Neonates have an immature renal system, which affects the excretion of drugs and their metabolites. This immaturity can lead to prolonged drug half-lives and an increased risk of toxicity. While hyperperistalsis, irregular temperature regulation, and smaller circulatory capacity can influence drug therapy, the immature renal system is the most significant factor. Nurses must consider this when administering medications to neonates and adjust dosages accordingly to ensure safety and efficacy.
Question 3 of 5
While a patient is receiving antilipemic therapy, the nurse knows to monitor the patient closely for the development of which problem?
Correct Answer: D
Rationale: Antilipemic agents are medications used to lower lipid levels in the blood, particularly cholesterol. These medications can have hepatotoxic effects, meaning they can potentially cause liver damage. Therefore, patients on antilipemic therapy need to be closely monitored for signs of liver dysfunction, such as elevated liver enzymes, jaundice, abdominal pain, or unexplained fatigue. Regular liver function tests are often conducted to ensure the liver is functioning properly while the patient is on this therapy. Monitoring for liver dysfunction is crucial to prevent complications and ensure the safety of the patient.
Question 4 of 5
What is the therapeutic use of Albuterol?
Correct Answer: A
Rationale: Albuterol is a medication commonly used to treat asthma and other respiratory conditions. It works by relaxing the muscles in the airways, allowing the air passages to widen and making it easier to breathe. This bronchodilation effect helps to relieve symptoms such as wheezing, shortness of breath, and chest tightness. Albuterol is classified as a short-acting beta-agonist, and its therapeutic use lies in its ability to provide quick relief during acute asthma attacks or to prevent exercise-induced bronchospasm.
