ATI Pharmacology Assessment 2 Questions
Question 1 of 5
The classi昀椀cation of digoxin is:
Correct Answer: D
Rationale: Digoxin belongs to the class of drugs known as cardiac glycosides. Cardiac glycosides are a group of compounds derived from plants and some animals that have the ability to increase the contractility of the heart muscle. Digoxin is commonly used to treat conditions such as congestive heart failure and irregular heart rhythms. It works by inhibiting the sodium-potassium pump in heart muscle cells, leading to an increase in intracellular calcium levels and subsequently improving the heart's pumping ability.
Question 2 of 5
The following drugs are most commonly associated with nephrotoxicity:
Correct Answer: A
Rationale: Gentamicin is associated with nephrotoxicity, particularly when administered in high doses or for prolonged periods.
Question 3 of 5
Which of the following antibacterials is most suitable for treatment of a lower urinary tract infection in a 28-year-old woman who is 10 weeks pregnant?
Correct Answer: A
Rationale: UTI in pregnancy needs safe, effective antibiotics. Amoxicillin, a penicillin, is safe (category B), effective against common pathogens (e.g., E. coli), and suitable in early pregnancy. Trimethoprim risks folate antagonism, avoided in first trimester. Tetracycline causes fetal bone/teeth damage, contraindicated. Erythromycin and flucloxacillin are less targeted for UTI. Amoxicillin's safety and efficacy make it ideal, protecting mother and fetus.
Question 4 of 5
After a severe auto accident, a patient has been taken to the trauma unit and has an estimated
Correct Answer: D
Rationale: Packed red blood cells (PRBCs) are the most appropriate product to administer after a severe auto accident when there is significant blood loss and anemia. PRBCs are used to increase the oxygen-carrying capacity of the blood and improve tissue oxygenation. They are specifically designed to deliver red blood cells without the unnecessary components found in whole blood. This targeted approach helps to avoid volume overload and reduce the risk of complications such as transfusion reactions. In a trauma situation where there is active bleeding and a need to rapidly restore oxygen-carrying capacity, PRBCs are the preferred blood product.
Question 5 of 5
The nurse will be administering an antitussive medication containing codeine to a patient. What is the priority assessment?
Correct Answer: C
Rationale: Codeine, an opioid antitussive, can cause respiratory depression as a side effect. The nurse must assess the patient’s respiratory rate before administration to ensure it is within a safe range (typically >12 breaths per minute). While lung sounds (B) and sputum consistency (D) are important, they are not the priority when administering a medication that can suppress respiration. Pulse oximetry (A) is useful but secondary to direct respiratory rate assessment.
