Question 1 of 5
A nurse is collecting data for a client who experienced a myocardial infarction prior to a cardiac arrest. Which of the following laboratory tests will identify early injury to the cardiac muscle?
Correct Answer: B

Question 2 of 5
A nurse is preparing to administer potassium chloride 20 mEq. The amount available is potassium chloride liquid 40 mEq/15 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 7.5
Rationale:
To calculate: (20 mEq / 40 mEq) × 15 mL = 7.5 mL, which is the correct dose to administer.
Question 3 of 5
A nurse is caring for a client with peripheral artery disease who has an arterial ulcer. Which of the following best describes the mechanism for developing the clinical problem?
Correct Answer: B
Rationale: Peripheral artery disease reduces blood flow, leading to poor oxygenation and slow healing of arterial ulcers, which is the primary mechanism for their development.
Question 4 of 5
A nurse is reinforcing teaching with a client who has peripheral vascular disease (PVD). The nurse should recognize that which of the following statements by the client indicates a need for further teaching?
Correct Answer: D
Rationale: Stockings with tight elastic tops can restrict blood flow, worsening symptoms in PVD. The client's statement indicates a misunderstanding, as these should be avoided.
