Question 1 of 5
A client has just been prescribed with methotrexate (Trexall) for the treatment of rheumatoid arthritis who did not respond to any other treatment. An important reminder for the client is to?
Correct Answer: C
Rationale: Methotrexate is an immunosuppressant, increasing the risk of infections. Strict hand washing and infection prevention measures are crucial. Clay-colored stools are not normal and may indicate liver dysfunction. Pregnancy is contraindicated due to the risk of fetal harm. Sunlight exposure should be limited to reduce the risk of photosensitivity reactions.
Question 2 of 5
A nurse is providing administration instruction to the wife of a client going home on intermittent enteral nutrition. Which information should the nurse include?
Correct Answer: A
Rationale: Cleaning equipment between each enteral feeding is vital to prevent bacterial contamination, as residual formula can foster microbial growth, risking infections like gastroenteritis in a client already nutritionally compromised. While limiting hang time is important, evidence suggests a 4-hour maximum, not 8, to minimize spoilage-though this isn't the focus here. Refrigerating unused feeding preserves its integrity, preventing degradation or bacterial proliferation, which is critical for safety. Keeping the insertion site clean reduces infection risk at the tube entry, a common complication in enteral therapy. Cleaning equipment stands out as a proactive step the wife can take between feedings, directly impacting hygiene and client safety, whereas other points address storage or site care, which, while essential, are secondary to the immediate post-feeding action of equipment maintenance in this context.
Question 3 of 5
An overwhelmed nursing student asks the instructor whether there are any tips that will make learning pharmacology easier. The instructor gives an example of the anticoagulant heparin. The instructor indicates that knowing heparin and comparing other drugs to it will facilitate learning the many anticoagulants. Which approach is the instructor using?
Correct Answer: D
Rationale: The prototype approach uses a representative drug like heparin to learn a class (anticoagulants), comparing others to its traits-mechanism, effects, side effects-simplifying study. Mechanism of action is narrower. Generic or trade names focus on nomenclature, not learning strategy. Prototype leverages a familiar example, a proven method for mastering drug groups.
Question 4 of 5
The pregnant patient tells the nurse that her prescribed medication is not as effective as it was before her pregnancy. What is the best response by the nurse?
Correct Answer: A
Rationale: Pregnancy increases blood volume (50% more), diluting drugs, reducing efficacy-e.g., lower concentration per unit volume, a pharmacokinetic shift. Asking about administration checks adherence, not cause. Baby receiving drug is unlikely-placental transfer varies. Expiration is a guess, not tied to pregnancy. Blood volume explains the change, addressing her concern.
