Question 1 of 5
The nurse is caring for a client with a history of myasthenia gravis. The nurse should assess the client for:
Correct Answer: A
Rationale: Myasthenia gravis causes autoimmune destruction of acetylcholine receptors, leading to muscle weakness, especially in the eyes, face, and limbs, a key assessment finding.
Question 2 of 5
A female client is started on warfarin (Coumadin) 5 mg po bid. To adequately evaluate the effectiveness of the warfarin therapy, the nurse must know that this medication:
Correct Answer: C
Rationale: Thrombolytic agents (e.g., streptokinase) directly activate plasminogen, dissolving fibrin deposits, which in turn dissolves clots that have already formed. Heparin prevents the formation of clots by potentiating the effects of antithrombin III and the conversion of prothrombin to thrombin. Warfarin prevents the formation of clots by interfering with the hepatic synthesis of the vitamin K-dependent clotting factors. Platelets initiate the coagulation of blood by adhering to each other and the site of injury to form platelet plugs.
Question 3 of 5
A client has an order for Demerol 75 mg and atropine 0.4 mg IM as a preoperative medication. The Demerol vial contains 50 mg/mL, and atropine is available 0.4 mg/mL. How much medication will the nurse administer in total?
Correct Answer: 1.7
Rationale: Demerol: 75 mg ÷ 50 mg/mL = 1.5 mL. Atropine: 0.4 mg ÷ 0.4 mg/mL = 1 mL.
Total = 1.5 + 1 = 2.5 mL. However, the closest answer is 1.7 mL (
B), possibly due to a typo in the question or answer choices.
Question 4 of 5
A client has been diagnosed with thrombophlebitis. She asks, 'What is the most likely cause of thrombophlebitis during my pregnancy?' The nurse explains:
Correct Answer: A
Rationale: During pregnancy, the potential for thromboses increases owing to the increased levels of coagulation factors and a decrease in the breakdown of fibrin.
Question 5 of 5
The charge nurse is assigning staff for the day. Staff consists of an RN, an LPN, and a certified nursing assistant. Which client assignment should be given to the nursing assistant?
Correct Answer: B
Rationale: A stable stroke client (hospitalized for two days) is appropriate for a nursing assistant, who can assist with basic care (e.g., hygiene, mobility). Recent surgery (
A), PCA morphine (
C), and new admissions (
D) require higher-level nursing skills.
