Question 1 of 5
A client with cancer is prescribed methotrexate. Which supplement should the healthcare provider recommend to reduce the risk of methotrexate toxicity?
Correct Answer: A
Rationale: The correct answer is folic acid. Methotrexate is a folic acid antagonist, and supplementing with folic acid can help reduce the risk of methotrexate toxicity. Folic acid supplementation is commonly recommended to counteract the effects of methotrexate on folate metabolism.
Question 2 of 5
When instructing a client with a new prescription for Timolol on how to insert eye drops, which area should the nurse instruct the client to press on to prevent systemic absorption of the medication?
Correct Answer: B
Rationale: Pressing on the nasolacrimal duct, located near the inner corner of the eye, blocks the lacrimal punctum and prevents the medication from entering the systemic circulation. This technique helps to ensure the medication stays localized in the eye, enhancing its therapeutic effect while minimizing systemic side effects.

A client is prescribed Digoxin. Which of the following findings should the nurse monitor as a sign of potential toxicity?
Correct Answer: A
Rationale: Bradycardia is a common sign of Digoxin toxicity. Digoxin can lead to toxicity, which can manifest as various signs and symptoms, including bradycardia. Monitoring the client's heart rate closely is crucial to detect and manage potential toxicity early.
Question 4 of 5
A healthcare provider is preparing to administer a transfusion of a unit of packed red blood cells (PRBCs) for a client who has severe anemia. Which of the following interventions will prevent an acute hemolytic reaction?
Correct Answer: B
Rationale: The correct answer is to obtain help from another healthcare provider to confirm the correct client and blood product. This action is crucial in preventing an acute hemolytic reaction, which is caused by ABO or Rh incompatibility. Verifying the correct client and blood product before the transfusion ensures that there are no errors in identification, reducing the risk of a potentially life-threatening reaction.
