Question 1 of 5
A nurse is educating a client who has a new prescription for digoxin. Which of the following statements should the nurse make?
Correct Answer: C
Rationale: The correct answer is C: Check your heart rate 1 hour after taking the medication. This statement is important as digoxin can affect heart rate, and monitoring it helps assess for potential toxicity. Option A is incorrect because taking a missed dose could lead to overdose. Option B is unrelated to digoxin therapy. Option D is incorrect as visual changes are not an expected side effect of digoxin. It is crucial for nurses to prioritize patient safety by providing accurate and relevant information.
Question 2 of 5
A nurse is monitoring a client who received a local injection of lidocaine. Which of the following responses should the nurse expect?
Correct Answer: D
Rationale: The correct answer is D: Client reports of numbness in the area. Lidocaine is a local anesthetic that blocks nerve impulses, resulting in numbness in the area where it was injected. This is an expected response as it indicates the medication is working as intended. Ventricular fibrillation (
A) is a serious cardiac arrhythmia unrelated to local lidocaine injection. Tachycardia (
B) is an increased heart rate and not a typical response to lidocaine. Client reports of increased pain in the area (
C) would be unexpected and might indicate a problem with the injection or the medication.
Question 3 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: B
Rationale:
Correct Answer: B. Oxycodone causes central nervous system depression.
Rationale: Oxycodone is an opioid analgesic that acts on the central nervous system (CNS) to relieve pain. One common side effect of opioids like oxycodone is respiratory depression, where the CNS is suppressed, leading to a decrease in respiratory rate. In this case, the client's respiratory rate of 8/min is indicative of CNS depression caused by the oxycodone.
Summary of other choices:
A: Oxycodone does not block sodium channels to suspend nerve conduction.
C: Oxycodone does not inhibit prostaglandin synthesis.
D: Oxycodone does not promote vasodilation of cranial arteries.
Therefore, choices A, C, and D are incorrect in the context of the client's respiratory rate being 8/min.
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: D
Rationale: The correct answer is D: PT (Prothrombin Time). Prothrombin Time measures the clotting ability of the blood, which is crucial for monitoring warfarin therapy. Warfarin is an anticoagulant that works by inhibiting clotting factors dependent on Vitamin K, such as prothrombin. By reviewing the PT before administering warfarin, the nurse can ensure the client's blood is clotting appropriately.
A: PTT (Partial Thromboplastin Time) measures the intrinsic pathway of the clotting cascade and is not specific to warfarin therapy.
B:
Total iron-binding capacity is unrelated to warfarin therapy.
C: WBC (White Blood Cell count) is not necessary to review before administering warfarin.
Question 5 of 5
A nurse is assessing the vital signs of a client who is taking amiodarone. The nurse should anticipate which of the following findings as an adverse effect of the medication?
Correct Answer: B
Rationale: The correct answer is B: Bradycardia. Amiodarone is an antiarrhythmic medication that can cause bradycardia as an adverse effect due to its action on the heart's electrical conduction system. This can lead to a slow heart rate, which the nurse should monitor for. The other choices are incorrect because hypertension (
A) is not a common adverse effect of amiodarone, fever (
C) is not typically associated with this medication, and bradypnea (
D) refers to slow breathing rate, which is not a typical adverse effect of amiodarone.
