A 77-year-old long-term care resident with obesity and limited mobility is prescribed sequential compression devices (SCDs) when in bed. The nurse finds the SCD pump turned on, but the sleeves are loosely wrapped and sliding down; the resident has 1+ edema and calf circumferences are equal at 35 cm bilaterally. Which action is MOST important for ensuring the effectiveness of the compression device?

Apply powder under the sleeves to prevent sweating and leave the loose fit for comfort

Place a pillow under the knees to keep the sleeves from sliding

Ask the RN to discontinue SCDs and switch to anti-embolism stockings

Rewrap and refasten the sleeves so they fit snugly, then confirm the pump inflates and deflates at the ordered setting

Explanation

This question tests understanding of DVT prevention and ensuring proper SCD application in obese residents with limited mobility. The priority concern is that loosely fitted SCDs provide inadequate compression for DVT prevention. Rewrapping sleeves for snug fit and confirming pump function at ordered settings (Option A) ensures the device provides therapeutic compression. Option B (powder application with loose fit) maintains ineffective compression; Option C (switching to stockings) requires physician order and may be less effective for this patient; Option D (pillow under knees) could impede venous return and doesn't address the loose fit. The decision-making principle is that SCDs must maintain proper fit throughout use to provide effective intermittent pneumatic compression. A transferable strategy is to check SCD placement and fit at regular intervals, especially in patients with obesity where sleeves may slide more easily, and readjust as needed.

A 66-year-old client is hospitalized and immobile after a stroke; sequential compression devices (SCDs) are ordered. The nurse finds the SCD sleeves applied over knee-high anti-embolism stockings, and the client has redness at the back of the knees; calf circumferences are equal at 32 cm bilaterally and there is 1+ ankle edema. What is the PRIORITY nursing action for this client?

Remove the devices, assess skin and circulation, then reapply the SCDs correctly per facility policy and report the skin redness to the RN

Remove the SCD sleeves and keep the stockings on only until the redness resolves

Leave both devices in place to maximize compression and reassess in 4 hours

Ask the RN to prescribe a topical antibiotic for the redness

Explanation

This question tests understanding of DVT prevention and proper compression device application to prevent skin complications. The priority concern is addressing improper device layering that has caused skin irritation at pressure points. Removing devices, assessing skin and circulation, reapplying SCDs correctly per policy, and reporting skin redness (Option C) ensures safe compression therapy while addressing the complication. Option A (leaving both devices) continues harmful pressure; Option B (keeping only stockings) may provide inadequate compression; Option D (topical antibiotic) doesn't address the mechanical cause. The decision-making principle is that compression devices should never be layered as this creates excessive pressure and skin breakdown risk. A transferable strategy is to ensure only one type of compression device is used at a time, following facility protocols for device selection based on patient mobility and risk factors.

A 59-year-old client is 1 day post-operative after a total knee replacement and is using compression stockings. The nurse notes the operative leg has 2+ edema at the ankle and calf circumference of 41 cm on the operative side versus 38 cm on the non-operative side; the client has been out of bed only once today. What is the PRIORITY nursing action for this client?

Remove the stocking and assess the leg for pain, warmth, color, and pulses, and report the increased swelling to the RN

Keep the stocking off for the rest of the shift to prevent skin irritation

Apply the compression stocking by rolling it into a tight band and stretching it over the calf quickly

Massage the calf firmly to improve circulation before reapplying the stocking

Explanation

This question tests understanding of DVT prevention and appropriate response to concerning findings in a post-operative knee replacement patient. The priority concern is recognizing potential DVT development in the operative leg with increased edema and asymmetric calf measurements. Removing the stocking to assess for pain, warmth, color changes, and pulses while reporting increased swelling to the RN (Option B) ensures proper evaluation of potential complications. Option A (rolling stocking tightly) could compromise circulation; Option C (massaging the calf) is contraindicated if DVT is suspected as it could dislodge a clot; Option D (keeping stocking off) removes necessary compression therapy. The decision-making principle is that new or worsening unilateral leg swelling post-operatively requires immediate assessment to rule out DVT. A transferable strategy is to perform comprehensive leg assessments before compression device application and when any changes occur, documenting and reporting concerning findings promptly.

A 65-year-old hospitalized client is on bed rest after a stroke and has SCDs in place. Assessment shows new redness and tenderness along the back of the left calf; left calf circumference is 37 cm and right is 34 cm. What is the PRIORITY nursing action for this client?

Stop using the SCD on the affected leg and report the findings to the RN promptly

Apply a warm compress to the calf and reassess in 2 hours

Massage the calf gently to reduce tenderness

Encourage the client to perform vigorous ankle circles to break up a possible clot

Explanation

This question tests understanding of DVT prevention and use of compression devices. The priority concern is new unilateral calf redness, tenderness, and enlargement, suggesting possible DVT, requiring immediate cessation of compression on the affected leg to avoid clot dislodgement. Stopping SCD use on the affected leg and reporting promptly allows for safe evaluation and management. Encouraging ankle circles or massaging risks embolization; applying warmth could worsen inflammation. The decision-making principle in compression therapy is to discontinue use on symptomatic legs and escalate for suspected thrombosis. This prevents complications like pulmonary embolism. A transferable strategy is to halt compression and notify providers upon detecting unilateral symptoms, followed by monitoring vital signs to ensure timely DVT intervention.

A 79-year-old long-term care resident with limited mobility is using sequential compression devices (SCDs) for DVT prevention. The nurse assesses that the sleeves inflate and deflate regularly, the resident’s calves are equal at 34 cm bilaterally, pedal pulses are present, and there is no redness or warmth; ankle edema remains at baseline 1+. Which observation indicates the compression device is working EFFECTIVELY?

The resident reports the sleeves feel very tight and leaves them off most of the day

The SCD sleeves cycle inflation and deflation as ordered while the resident is in bed

The resident’s blood pressure is 148/86 mm Hg after breakfast

The nurse massages the calves each shift to improve circulation

Explanation

This question tests understanding of DVT prevention and recognition of effective compression device function. The priority concern is confirming that SCDs are providing appropriate intermittent pneumatic compression. Regular inflation and deflation cycles while the resident is in bed (Option A) indicates proper device function and effective DVT prophylaxis. Option B (elevated blood pressure) is unrelated to SCD effectiveness; Option C (tight feeling/non-use) indicates poor compliance; Option D (calf massage) is inappropriate and potentially dangerous if clots are present. The decision-making principle is that effective compression therapy requires consistent device function with regular compression cycles. A transferable strategy is to observe complete SCD cycles during assessments, document proper function, and address any patient concerns about comfort to ensure continuous use.

6

A 62-year-old post-operative knee replacement client is using compression stockings and is ambulating short distances with assistance. Assessment shows the affected leg has 1+ edema and calf circumference increased from 39 cm to 41 cm since morning; the client reports new calf pain rated 6/10. The nurse should REPORT which finding to the RN?

New calf pain with an increase in calf circumference since morning

Client requests an extra blanket for warmth

Compression stocking fabric feels slightly damp from perspiration

Client states the hospital food is not appealing

Explanation

This question tests understanding of DVT prevention and recognition of acute DVT symptoms in post-operative patients using compression stockings. The priority concern is identifying signs of possible DVT development despite prophylactic measures. New calf pain with increased circumference since morning (Option A) indicates potential DVT formation requiring immediate RN notification. Option B (extra blanket request) is a comfort measure; Option C (damp stocking) is expected with wear; Option D (food preferences) is unrelated to DVT risk. The decision-making principle is that new onset calf pain with measurable swelling progression requires immediate evaluation for possible DVT. A transferable strategy is to establish baseline measurements post-operatively and monitor for changes in circumference, especially when accompanied by new pain, warmth, or redness.

7

A 72-year-old long-term care resident has limited mobility after a recent fall and a history of deep vein thrombosis (DVT). The resident is using a sequential compression device (SCD) while in bed; the nurse notes mild bilateral ankle edema (1+) and calf circumferences of 36 cm (right) and 36 cm (left). Which action is MOST important for ensuring the effectiveness of the compression device?

Request an order from the RN to start a heparin infusion for DVT prevention

Remove the SCD sleeves once per shift to allow uninterrupted sleep

Verify the sleeves are the correct size and are snug without constricting, and that the pump is on and cycling as ordered

Measure the resident’s oral intake and output each shift to evaluate edema

Explanation

This question tests understanding of DVT prevention and proper use of sequential compression devices (SCDs) in long-term care residents with limited mobility. The priority concern is ensuring the SCD is functioning properly to provide effective DVT prophylaxis. Verifying correct sleeve size, proper fit (snug without constriction), and confirming the pump is cycling as ordered (Option B) ensures optimal compression therapy effectiveness. Option A (removing sleeves for sleep) defeats the purpose of continuous DVT prevention; Option C (heparin infusion) requires a physician order and is not within LPN scope; Option D (measuring I&O) relates to fluid balance but doesn't directly ensure SCD effectiveness. The decision-making principle is that mechanical compression devices must fit properly and function continuously to prevent venous stasis. A transferable strategy is to check SCD fit and function at every assessment, ensuring sleeves are properly sized, positioned, and the pump is cycling appropriately.

A 58-year-old client is 2 days post–knee replacement surgery in the hospital. The client has obesity and is ambulating short distances with a walker; compression stockings are in place. The nurse notes the operative leg calf circumference increased from 40 cm to 43 cm since morning with 2+ edema. What is the PRIORITY nursing action for this client?

Encourage increased oral fluids and recheck the circumference at end of shift

Remove the stocking and reapply it loosely to reduce pressure

Massage the calf to improve circulation while the stockings are on

Report the increased calf circumference and swelling to the RN for further evaluation

Explanation

This question tests understanding of DVT prevention and use of compression devices. The priority concern is identifying potential postoperative DVT indicated by increased calf circumference and edema in the operative leg, which requires escalation for evaluation. Reporting the increased calf circumference and swelling to the RN ensures optimal assessment and possible intervention to rule out thrombosis. Massaging the calf could dislodge a clot; reapplying loosely reduces compression effectiveness; encouraging fluids and rechecking later delays necessary action. The decision-making principle in compression therapy is to prioritize reporting signs of complications like unilateral swelling over independent adjustments to the device. This approach prevents progression to serious events like embolism. A transferable strategy is to document baseline and ongoing measurements of leg circumferences and edema, reporting changes promptly to maintain effective DVT prevention.

9

A 61-year-old client is 1 day post–knee replacement surgery and is using compression stockings. The nurse finds the client sitting in a chair with stockings on; the client reports calf pain rated 6/10 on the operative side, and the calf circumference is 2.5 cm larger than the other leg. The nurse should REPORT which finding to the RN?

Client reports new unilateral calf pain with increased calf circumference compared to the other leg

Stockings are clean and dry with no visible wrinkles

Client states they are tired after physical therapy

Client requests an extra blanket because the room feels cold

Explanation

This question tests understanding of DVT prevention and use of compression devices. The priority concern is detecting early signs of DVT, such as new unilateral calf pain and increased circumference, which necessitate reporting to prevent escalation. Reporting the client's new unilateral calf pain with increased circumference compared to the other leg alerts the RN for further assessment and intervention. Requesting an extra blanket is unrelated; clean, wrinkle-free stockings are expected; fatigue after therapy is normal and not critical. The decision-making principle in compression therapy is to prioritize reporting symptoms suggestive of thrombosis over routine observations. This ensures timely management in postoperative clients. A transferable strategy is to assess and compare pain levels and calf measurements bilaterally during each shift, reporting variances to maintain effective monitoring for DVT.

A 70-year-old home health client is recovering 1 week after hip surgery and has risk factors for DVT including age and decreased mobility. The caregiver reports the compression stockings are worn “most of the day”; the nurse notes mild ankle edema and that the stockings are rolled down at the top. Which action is MOST important for ensuring the effectiveness of the compression device?

Teach the caregiver to avoid rolling the stockings down and to smooth them flat to prevent a tight band

Ask the caregiver to double the stockings for extra compression

Tell the caregiver to apply the stockings only when swelling is present

Request the RN to prescribe a new pain medication before using stockings

Explanation

This question tests understanding of DVT prevention and use of compression devices. The priority concern is incorrect application of compression stockings, such as rolling down, which creates a tourniquet effect and impairs circulation in a postoperative client. Teaching the caregiver to avoid rolling and smooth them flat prevents tight bands, ensuring optimal graduated compression to enhance venous return. Applying only when swelling is present is inconsistent; doubling stockings increases pressure unevenly; requesting pain medication does not address application errors. The decision-making principle in compression therapy is to educate on proper donning techniques to avoid constriction and maintain even pressure. This promotes effective DVT prevention without causing harm. A transferable strategy is to demonstrate and have caregivers return-demonstrate stocking application, reassessing fit regularly to ensure ongoing effectiveness.
