A nurse is collecting data from a client at a follow-up clinic visit for acute low back pain. A goal for this client is to use proper body mechanics at all times. Which of the following findings indicates that the client is meeting this goal?
The client stands with his feet close together when lifting an object.
When moving an object to one side, the client puts his weight on his heels.
When pushing an object the client moves his front foot backward.
The client faces the direction of movement when sliding an object across the floor.
The Correct Answer is D
A. Standing with feet close together when lifting an object does not provide adequate support or balance, increasing the risk of injury. Proper body mechanics involve keeping feet apart for a stable base of support.
B. Putting weight on the heels when moving an object is not advised. Instead, one should keep the weight distributed over the whole foot for stability.
C. When pushing an object, stepping forward with the front foot (rather than moving it backward) helps to maintain balance and applies proper force.
D. Facing the direction of movement is a correct application of proper body mechanics, as it prevents twisting of the spine, reduces strain on the back, and promotes safe movement.

Correct Answer is B
Explanation
A. A cooling blanket is not typically needed unless there is a fever or postoperative temperature dysregulation, which is not a standard intervention in this case.
B. Monitoring daily weight is essential following valve replacement to detect fluid retention or heart failure, which can indicate compromised cardiac function.
C. Opioid medications may be necessary, but they should be prescribed according to the client’s pain needs rather than a routine intervention.
D. PTT levels are usually monitored for clients on anticoagulants, but since the client has a biologic valve, anticoagulation therapy is not always required as with mechanical valves.
Correct Answer is A
Explanation
A. A positive result in a Tensilon test is indicated by a temporary improvement in muscle strength following the administration of edrophonium (Tensilon), confirming the diagnosis of myasthenia gravis.
B. A "pill-rolling" tremor is associated with Parkinson's disease, not myasthenia gravis, and is not relevant to this test.
C. While muscle electrical activity can be assessed in other tests, the Tensilon test specifically evaluates muscle strength changes, not electrical charge intensity.
D. No change in muscle strength would suggest a negative result for myasthenia gravis, indicating that the test did not confirm the diagnosis.
