- The two drugs must always be taken together for life
- Warfarin takes several days to reach its full anticoagulant effect
- Enoxaparin increases the absorption of warfarin
- Enoxaparin prevents the side effects of warfarin
Show answer and rationale
Answer: B. Warfarin takes several days to reach its full anticoagulant effect
Warfarin's effect depends on depletion of existing clotting factors, which takes several days, so a parenteral anticoagulant is overlapped until the INR is therapeutic.
Reference: Standard nursing pharmacology – warfarin
- Advise the patient to double the next dose
- Report it promptly because it may indicate a blood disorder such as agranulocytosis
- Reassure the patient that these are expected side effects
- Advise throat lozenges and continue the drug
Show answer and rationale
Answer: B. Report it promptly because it may indicate a blood disorder such as agranulocytosis
Carbamazepine can cause bone marrow suppression; signs of infection need an urgent full blood count and review.
Reference: Standard nursing pharmacology – carbamazepine
- 300 mg
- 450 mg
- 200 mg
- 150 mg
Show answer and rationale
Answer: A. 300 mg
Dose = 15 mg/kg × 20 kg = 300 mg.
Reference: Standard dosage calculation – weight-based dosing
- Tell the patient the prescriber insists the tablet must be taken
- Explore the reason for refusal, provide information, and document and report the refusal if the patient still declines
- Hide the tablet in the patient's breakfast
- Leave the tablet on the bedside table for later
Show answer and rationale
Answer: B. Explore the reason for refusal, provide information, and document and report the refusal if the patient still declines
A competent patient has the right to refuse; the nurse explores concerns, educates, respects the decision, documents and informs the prescriber. Covert administration and leaving medicines unattended are unsafe.
Reference: Potter & Perry Fundamentals – medication administration
- 50 drops/min
- 12 drops/min
- 100 drops/min
- 25 drops/min
Show answer and rationale
Answer: A. 50 drops/min
(50 mL × 60 drops/mL) ÷ 60 min = 50 drops/min. With a 60 drops/mL set, drops per minute equal mL per hour.
Reference: Standard dosage calculation – gravity drip rates
