A nurse is planning care for a client who has a new prescription for parenteral nutrition (PN) in 20% dextrose and fat emulsions. Which of the following is an appropriate action to include in the plan of care?
Change the PN infusion bag every 48 hr.
Administer the PN and fat emulsion separately.
Prepare the client for a central venous line.
Obtain a random blood glucose daily.
The Correct Answer is C
Rationale: Parenteral nutrition (PN) is a method of providing essential nutrients to the body through a central vein. PN is indicated for clients who cannot take oral or enteral nutrition due to intestinal failure or other conditions. PN requires a central venous line because the solution is hypertonic and can cause thrombophlebitis or damage to peripheral veins. A central venous line also allows for better monitoring of fluid balance and electrolyte levels.

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
Explanation
Cheyne-Stokes respirations are an abnormal pattern of breathing characterized by progressively deeper, and sometimes faster, breathing followed by a gradual decrease that results in a temporary stop in breathing called an apnea. The pattern repeats, with each cycle usually taking 30 seconds to 2 minutes. This type of breathing may occur in people who are dying due to heart failure, stroke, brain injury or other causes. The nurse should expect to observe irregular respirations with frequent periods of apnea in the client who is dying and having Cheyne-Stokes respirations.
