A nurse is preparing to insert a peripheral IV catheter into a client's arm. Which of the following actions should the nurse take to help dilate the vein?
Instruct the client to flex their arm with the hand open.
Dangle the client's arm over the edge of the bed.
Apply a cool compress to the vein for 10 min.
Stroke the skin near the vein in an upward direction.
The Correct Answer is B
Dangling the client's arm over the edge of the bed helps dilate the vein by increasing venous pressure due to gravity. Flexing the arm with the hand open does not affect venous dilation and may cause muscle tension that can impede insertion. Applying a cool compress constricts rather than dilates the vein by causing vasoconstriction. Stroking the skin near the vein may irritate or damage the vein and does not promote dilation.

Correct Answer is ["A","B"]
Explanation
A cuff that is too narrow or too wide can result in inaccurate blood pressure readings. The cuff should be snug but not tight and cover about 80% of the arm length. The pressure should be released at a rate of 2 to 3 mm per second to avoid missing auscultatory gaps or causing discomfort to the client.
Correct Answer is ["A","B","E"]
Explanation
The nurse should secure restraints to allow three fingers to slide under the restraints to prevent circulation impairment and nerve damage. The nurse should also assess skin temperature and color before applying the restraints to establish a baseline and monitor for signs of ischemia. The nurse should ensure that the client's bed is in the lowest position to reduce the risk of injury from falls. The nurse should pad bony prominences before applying the restraints to prevent skin breakdown and pressure ulcers. The nurse should not attach the client's restraints to the bed rail because this can cause injury if the bed is moved or adjusted. The nurse should attach the restraints to a part of the bed frame that moves with the client, such as the mattress support platform.
