A nurse is assessing a client who is receiving heparin therapy for deep-vein thrombosis.
Which of the following findings should indicate to the nurse that the therapy is effective?

Platelets within the expected reference range.

Decreased INR.

Presence of pedal pulses bilaterally.

Reduced calf circumference.

Answer and Explanation

The Correct Answer is D

Heparin therapy is used to prevent thrombus propagation and distal embolization while allowing the endogenous fibrinolytic system to dissolve existing clots in deep-vein thrombosis (DVT)1.

A reduction in calf circumference may indicate that the clot is dissolving and the therapy is effective.

Choice A is wrong because platelets within the expected reference range do not necessarily indicate that heparin therapy for DVT is effective.

Choice B is wrong because INR (International Normalized Ratio) is used to monitor warfarin therapy, not heparin therapy.

Choice C is wrong because the presence of pedal pulses bilaterally does not necessarily indicate that heparin therapy for DVT is effective.

Correct Answer is D

Explanation

Ceftriaxone is contraindicated for this client because it is a cephalosporin antibiotic, which has a similar structure to penicillin and can cause cross-reactivity in individuals with a penicillin allergy.

Choice A is wrong because Vancomycin is not a beta-lactam antibiotic and does not have cross-reactivity with penicillin.

Choice B is wrong because Clarithromycin is a macrolide antibiotic and does not have cross-reactivity with penicillin.

Choice C is wrong because Metronidazole is a nitroimidazole antibiotic and does not have cross-reactivity with penicillin.

A. 1 tablet. B. 3 tablets. C. 4 tablets. D. 8 tablets.

Correct Answer is B

Explanation

Step 1: Convert weight from lb to kg.

88 lb ÷ 2.2 = 40 kg

Step 2: Calculate total daily dose in mg.

150 mg/kg × 40 kg = 6000 mg

Step 3: Calculate dose per administration (every 6 hr).

6000 mg ÷ 4 = 1500 mg

Step 4: Calculate number of tablets per dose.

1500 mg ÷ 500 mg/tab = 3 tablets

Answer:

3 tablets per dose.
