Question 1 of 5
A nurse is assessing a client's ability to ambulate with crutches using a three-point gait. Which of the following actions should the nurse identify as a risk to the client's safety?
Correct Answer: D
Rationale: Placing partial weight on the affected leg while ambulating with crutches using a three-point gait is incorrect and can jeopardize safety by potentially causing injury or instability.
Question 2 of 5
A nurse is reviewing the EKG strip of a client who has prolonged vomiting. Which of the following abnormalities on the client's EKG should the nurse interpret as a sign of hypokalemia?
Correct Answer: B
Rationale: An abnormally prominent U wave is a classic sign of hypokalemia on an EKG.
Question 3 of 5
A nurse is preparing to administer penicillin G benzathine 1.2 million units IM now. The amount available is penicillin G benzathine 600,000 units/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 2
Rationale:
To administer the correct dose of penicillin G benzathine, which is 1.2 million units, and given that the available concentration is 600,000 units per mL, the nurse should calculate the volume to administer based on these values. By dividing the prescribed dose by the concentration available, the nurse can determine the volume needed for injection. In this case, 1.2 million units divided by 600,000 units per mL results in 2 mL.
Question 4 of 5
A nurse is caring for a client who is receiving total parenteral nutrition via a peripherally inserted central catheter (PICC). When assessing the client, the nurse notes swelling of the client's arm above the PICC insertion site. Which of the following actions should the nurse take first?
Correct Answer: D
Rationale: Measuring the circumference of both upper arms is the first action to assess the extent of the swelling and compare it to the other arm, which will help determine the severity of the issue.
Question 5 of 5
A nurse is administering morphine 2 mg IV every 2 to 4 hr to a client who has an abdominal incision. The nurse should monitor the client for which of the following adverse effects?
Correct Answer: C
Rationale: Orthostatic hypotension is a known adverse effect of morphine due to its potential to cause vasodilation and lower blood pressure, especially when the client changes positions.
