Question 1 of 5
An adult has a coagulation time of 20 minutes. The nurse should observe the client for which of the following?
Correct Answer: B
Rationale: The normal clotting time is 9 to 12 minutes. A prolonged clotting time suggests a bleeding tendency, so the client should be observed for signs of bleeding, such as ecchymotic areas. Blood clots would occur with a shorter clotting time. Jaundice is related to liver damage or red blood cell breakdown. Infection is associated with low white blood cell counts.
Question 2 of 5
The client is exhibiting sinus bradycardia, is complaining of syncope and weakness, and has a BP of 98/60. Which collaborative treatment should the nurse anticipate being implemented?
Correct Answer: C
Rationale: Symptomatic bradycardia (syncope, hypotension) often requires a pacemaker (
C). Thrombolytics (
A) are for MI, assessment (
B) is ongoing, and cardioversion (
D) is for tachydysrhythmias.
Question 3 of 5
Which prothrombin time value would be considered normal for a client who is receiving warfarin (Coumadin)?
Correct Answer: B
Rationale: For a client receiving warfarin, the prothrombin time should be 1.5 to 2 times the normal value (11 to 12.5 seconds). Twenty seconds falls within this therapeutic range. Twelve seconds is normal for someone not on warfarin. Sixty seconds is normal for a partial thromboplastin time (PTT) test, and 98 seconds would be therapeutic for heparin, not warfarin.
Question 4 of 5
An adult is diagnosed with hypertension. He is prescribed chlorothiazide (Diuril) 500 mg PO. What nursing instruction is essential for him?
Correct Answer: C
Rationale: Chlorothiazide, a diuretic, can cause potassium loss. Consuming potassium-rich foods like orange juice or bananas helps prevent hypokalemia.
Question 5 of 5
The nurse is functioning in the role of medication nurse during a code. Which should the nurse implement when administering amiodarone for ventricular tachycardia?
Correct Answer: D
Rationale: Amiodarone for VT is administered via IV pump (
D) per ACLS (e.g., 150 mg over 10 min). Rapid infusion (
A) risks hypotension, direct push (
B) is incorrect, and questioning (
C) is unnecessary.
