Extract:
Question 1 of 5
A nurse is assessing a client's understanding of a surgical procedure prior to witnessing their signature on the informed consent form. The nurse determines that the client does not understand what the procedure will involve. Which of the following actions should the nurse take?
Correct Answer: D
Rationale: The provider must ensure the client fully understands the procedure for informed consent.
Question 2 of 5
A nurse is assessing a client who has a central venous catheter (CVC) with intravenous (IV) fluids infusing. The client suddenly develops shortness of breath, and the nurse notes that the IV tubing and needleless connector device are disconnected. Which of the following actions should the nurse take first?
Correct Answer: A
Rationale: Closing the clamp prevents air embolism, the immediate risk in a disconnected CVC.
Question 3 of 5
A nurse is preparing to administer enoxaparin 0.75 mg/kg subcutaneously to a client who weighs 154 lb. The amount available is enoxaparin 60 mg/0.6 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: 0.5 mL.
Rationale: Calculation: 154 lb = 70 kg; 0.75 mg/kg × 70 kg = 52.5 mg; (52.5 mg / 60 mg) × 0.6 mL = 0.525 mL, rounded to 0.5 mL.
Question 4 of 5
A nurse is preparing to administer potassium chloride 10 mEq IV over 1 hr to a client. Available in potassium chloride 10 mEq in 100 mL of 0.9% sodium chloride. The nurse should set the infusion pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 100 mL/hr.
Rationale: 10 mEq in 100 mL over 1 hr requires an infusion rate of 100 mL/hr.
Question 5 of 5
A nurse is caring for a client who is experiencing anxiety as well as numbness and tingling of the lips and fingers. The client's ABGs are pH 7.48, PCO2 30 mm Hg, HCO3 24 mEq/L, PaO2 85 mm Hg. Which of the following acid-base imbalances should the nurse identify that the client is experiencing?
Correct Answer: A
Rationale: The elevated pH and decreased PCO2 suggest respiratory alkalosis, caused by excessive ventilation leading to decreased carbon dioxide levels.
