A nurse is providing preoperative teaching to a client about promoting circulation during the postoperative period.
Which of the following instructions should the nurse include?
Participate in range-of-motion exercises
Use an incentive spirometer every 4 hours
Remain on bed rest for 24 hours following the procedure
Place a pillow under your knees while in bed
The Correct Answer is A
This instruction will help the client to prevent venous stasis and thrombosis, which are common postoperative complications. Range-of-motion exercises promote blood circulation and prevent muscle atrophy and contractures.
Choice B. “Use an incentive spirometer every 4 hours.” is wrong because it is not related to promoting circulation, but rather to improving lung expansion and preventing atelectasis and pneumonia. Using an incentive spirometer is also important for postoperative clients, but it does not address the question.
Choice C. “Remain on bed rest for 24 hours following the procedure.” is wrong because it is the opposite of promoting circulation.
Bed rest increases the risk of venous stasis, thrombosis, and pulmonary embolism. Postoperative clients should be encouraged to ambulate as soon as possible, unless contraindicated.
Choice D. “Place a pillow under your knees while in bed.” is wrong because it also impairs circulation and increases the risk of thrombosis.
Placing a pillow under the knees can cause pressure on the popliteal veins and reduce blood flow. Postoperative clients should avoid this position and keep their legs in a neutral or slightly elevated position.

Correct Answer is B
Explanation
The correct answer is choice b. "I can start the medication 30 minutes earlier."Choice A rationale: This is an inappropriate response, as the nurse should not adjust the time and schedule for the administration of alteplase recombinant, which is a time-sensitive medication used to treat a thrombus in the coronary artery. The administration of this medication must be done within a specific time frame to be effective.Choice B rationale: This is the correct answer. Alteplase recombinant is a thrombolytic medication used to dissolve blood clots in the coronary artery. It is a time-sensitive medication, and it is crucial to administer it as soon as possible to minimize the damage to the heart muscle. Starting the medication 30 minutes earlier is an appropriate action to include in the plan of care, as it can help ensure the medication is administered within the recommended time frame.Choice C rationale: This is an inappropriate response. Alteplase recombinant should be administered within a specific time frame, typically within 3 to 4.5 hours of the onset of symptoms. Waiting up to 2 hours after the usual schedule time to give the medication would be outside the recommended time frame and could potentially reduce the effectiveness of the treatment.Choice D rationale: This is an inappropriate response. Alteplase recombinant should be infused at a specific rate, as recommended by the manufacturer or healthcare provider. Infusing the medication at a faster rate could increase the risk of adverse effects and should not be included in the plan of care without specific instructions from the healthcare provider.
Correct Answer is A
Explanation
The correct answer is choice A. INR.
Warfarin is a vitamin K antagonist that inhibits the synthesis of factors II, VII, IX, and X in the liver.
These factors are part of the extrinsic and common pathways of coagulation, which are measured by the prothrombin time (PT) and the international normalized ratio (INR).
The INR is a standardized way of reporting the PT that accounts for the variability of different reagents and instruments.
The INR is used to monitor the therapeutic effect of warfarin and to adjust the dose accordingly.
The target INR range depends on the indication for warfarin, but it is usually between 2 and 3 for most conditions.
Choice B is wrong because fibrinogen level is not affected by warfarin.
Fibrinogen is a precursor of fibrin, which forms the final step of the coagulation cascade.
Fibrinogen level can be decreased in conditions such as disseminated intravascular coagulation (DIC), liver disease, or severe bleeding. Choice C is wrong because aPTT is not affected by warfarin.
aPTT measures the intrinsic and common pathways of coagulation, which are mainly dependent on factors VIII, IX, XI, and XII.
These factors are not inhibited by warfarin.
aPTT is used to monitor the effect of heparin, a direct antithrombin agent that inhibits thrombin and factor Xa.
Choice D is wrong because platelet count is not affected by warfarin.
Platelets are cell fragments that adhere to damaged blood vessels and form aggregates to initiate hemostasis.
Platelet count can be decreased in conditions such as immune thrombocytopenia (ITP), heparin-induced thrombocytopenia (HIT), or bone marrow suppression.
Normal ranges:
- INR: 0.8-1.2
- Fibrinogen: 200-400 mg/dL
- aPTT: 25-35 seconds
- Platelet count: 150-450 x 10^9/L References:
