Extract:
Question 1 of 5
A nurse is caring for a client who has thrombophlebitis and is receiving heparin by continuous IV infusion. The client asks the nurse how long it will take for the heparin to dissolve the clot. Which of the following responses should the nurse give?
Correct Answer: C
Rationale: Heparin is an anticoagulant that prevents new clot formation, not a thrombolytic that dissolves existing clots.
Question 2 of 5
The nurse is assessing a 39-year-old client with a blood pressure (BP) of 120/78 mm Hg at rest, a total cholesterol level of 210 mg/dL, HDL cholesterol of 58 mg/dL, triglycerides of 120 mg/dL, and a fasting blood glucose level of 98 mg/dL. Which risk factor for coronary artery disease requires further follow-up?
Correct Answer: D
Rationale: A total cholesterol level of 210 mg/dL is above the recommended level of less than 200 mg/dL, indicating a need for follow-up to manage this coronary artery disease risk factor.
Question 3 of 5
A patient with a history of hypertension treated with a diuretic and an angiotensin-converting enzyme (ACE) inhibitor arrives in the emergency department complaining of headache and blurred vision and has a blood pressure (BP) of 192/108 mmHg. Which question should the nurse ask to follow up on these findings?
Correct Answer: D
Rationale: Poor medication adherence is a common cause of elevated blood pressure despite treatment, likely explaining the severe BP elevation and symptoms.
Question 4 of 5
A nurse is preparing to administer 0.9% sodium chloride IV infusion 1-L bag at a rate of 125 mL/hr for a client who has rhabdomyolysis. The nurse should expect the IV pump to infuse over how many hours? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 8 hours
Rationale:
Total volume (1000 mL) divided by infusion rate (125 mL/hr) equals 8 hours.
Question 5 of 5
The nurse is reviewing laboratory values for a client receiving a continuous heparin infusion. Which of the following laboratory values should the nurse monitor?
Correct Answer: C
Rationale: Activated partial thromboplastin time (aPTT) is used to monitor heparin therapy effectiveness, ensuring a therapeutic dose without excessive bleeding risk.
