Extract:
Question 1 of 5
A nurse is providing teaching to a client about how to self-administer subcutaneous injections of enoxaparin. Which of the following instructions should the nurse include?
Correct Answer: A
Rationale: The air bubble in the enoxaparin syringe ensures the full dose is administered and should not be expelled.
Question 2 of 5
A nurse is caring for a client who is taking warfarin and reports taking several new herbal supplements. The nurse should identify which of the following supplements is contraindicated for concurrent use with warfarin?
Correct Answer: A
Rationale: Ginkgo biloba can increase the risk of bleeding when taken with warfarin due to its antiplatelet effects, making it contraindicated.
Question 3 of 5
A nurse is assessing a client who has started taking theophylline. Which of the following client findings should indicate to the nurse that the medication is effective?
Correct Answer: B
Rationale: Theophylline is used to manage asthma and COPD; decreased wheezing indicates improved airflow and effectiveness.
Question 4 of 5
A nurse is preparing to administer a scheduled dose of warfarin to a client. Which of the following laboratory tests should the nurse review prior to administration?
Correct Answer: A
Rationale: PT measures the time it takes for blood to clot, and it is particularly relevant for clients taking warfarin because warfarin works by inhibiting the synthesis of certain clotting factors, including factors II, VII, IX, and X, which are involved in the PT pathway. Monitoring PT levels helps ensure that the client is receiving an appropriate dose of warfarin to prevent clot formation without causing excessive bleeding.
Question 5 of 5
A nurse is assessing a client who has received oxycodone. The nurse notes that the client's respiratory rate is 8/min. The nurse should identify that which of the following is the pathophysiology for the client's respiratory rate?
Correct Answer: C
Rationale: Oxycodone is an opioid analgesic medication that acts primarily on the central nervous system (CNS) to relieve pain. One of the side effects of opioids like oxycodone is respiratory depression, where breathing becomes slow and shallow. This effect occurs because opioids suppress the activity of the respiratory centers in the brainstem, leading to decreased respiratory rate and depth.
