LPN Fundamentals of Nursing

Correct Answer: A

Rationale: Placing a pillow between the client's legs is crucial post hip arthroplasty surgery to prevent hip dislocation. This intervention helps maintain proper alignment and prevents legs from crossing midline, reducing the risk of hip prosthesis dislocation. Elevating the head of the bed to 45 degrees, positioning the client on the operative side, or keeping the client's legs adducted are not recommended postoperative interventions for a total hip arthroplasty, as they can increase the risk of complications and compromise the surgical site.

Correct Answer: C

Rationale: To ensure effective drainage, the catheter should be inserted 2-4 inches into the urethra. This length allows the catheter to reach the bladder, bypass the urethral sphincters, and ensure proper drainage without causing discomfort or injury. Using sterile gloves, cleaning the catheter with alcohol, and performing the procedure every 8 hours are not accurate instructions for self-catheterization.

Correct Answer: D

Rationale: Redness and warmth of the affected limb are classic signs of deep-vein thrombosis (DVT) due to inflammation and increased blood flow. These symptoms occur as a result of the blood clot obstructing normal blood flow and causing localized inflammation in the affected limb. Swelling of the affected limb, diminished peripheral pulses, and coolness are not typically associated with DVT. Swelling can be present but is often accompanied by the characteristic redness and warmth. Diminished pulses and coolness are more indicative of arterial insufficiency rather than venous thrombosis.

Correct Answer: C

Rationale: A petechial rash is a characteristic finding in clients with meningitis, indicating small, pinpoint hemorrhages under the skin. This rash results from the infection's impact on the blood vessels. Petechiae are important to recognize as they can help differentiate meningitis from other conditions with similar symptoms. Brudzinski's sign, neck stiffness, and positive Kernig's sign are more common physical exam findings in meningitis. Flaccid neck muscles and hypoactive deep tendon reflexes are not typically associated with meningitis.

Correct Answer: B

Rationale: When caring for a client with a prescription for wound irrigation, the nurse should cleanse the wound from the center outward. This technique helps prevent the introduction of microorganisms into the wound, reducing the risk of contamination and promoting effective wound healing. By using a circular motion from the cleanest area to the least clean areas, debris and bacteria are moved away from the wound site, decreasing the chances of infection.
