Question 1 of 5
A client receiving chemotherapy has a platelet count of 15,000 mm³ (15 x 10â¹/L). Based on this laboratory result, which form of precautions should the nurse implement?
Correct Answer: B
Rationale: When the platelet count is less than 20,000 mm³ (20 x 10â¹/L), the client is at risk for bleeding, and the nurse should institute bleeding precautions. Contact precautions are initiated in a client who has drainage from wounds that may be infectious. Respiratory precautions are instituted for a client with a respiratory infection that is transmitted by the airborne route. Neutropenic precautions would be instituted for a client with a low neutrophil count.
Question 2 of 5
The physician decides to change a client's current dose of I.M. meperidine hydrochloride (Demerol) to an oral dosage. The current I.M. dosage is 75 mg every 4 hours as needed. What dosage of oral meperidine should the client receive?
Correct Answer: B
Rationale: Oral meperidine has lower bioavailability than I.M., requiring a higher dose. A common conversion is 1.5–2 times the I.M. dose, making 150 mg every 4 hours appropriate.
Question 3 of 5
The nurse collecting data from the client is providing instructions regarding a new prescription for disulfiram. Which datum is important for the nurse to obtain before beginning the administration of this medication?
Correct Answer: B
Rationale: Disulfiram may be used as an adjunct treatment for selected clients with chronic alcoholism who want to remain in a state of enforced sobriety. Clients must abstain from alcohol intake for at least 12 hours before the initial dose of the medication is administered.
Therefore, it is important for the nurse to determine when the last alcoholic drink was consumed. The medication is used with caution in clients with diabetes mellitus, hypothyroidism, epilepsy, cerebral damage, nephritis, and hepatic disease. It is also contraindicated in severe heart disease, psychosis, or hypersensitivity related to the medication.
