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.
Prepare the client for a central venous line.
Obtain random blood glucose daily.
Administer the PN and fat emulsion separately.
The Correct Answer is B
Prepare the client for a central venous line.
Parenteral nutrition (PN) with 20% dextrose and fat emulsions is a hypertonic solution that requires infusion through a central venous line to prevent damage to peripheral veins.

Choice A is wrong because the PN infusion bag should be changed every 24 hours, not every 48 hours.
Choice C is wrong because blood glucose should be monitored more frequently than once daily when initiating PN therapy.
Choice D is wrong because PN and fat emulsions can be administered together in a total nutrient admixture (TNA)1.

Correct Answer is C
Explanation
The Weber test is a screening test for hearing performed with a tuning fork that can detect unilateral conductive hearing loss and unilateral sensorineural hearing loss.
To perform Weber’s test, strike the fork against your knee or elbow, then place the base of the fork in the midline, high on the patient’s forehead.

Choice A is wrong because delivering a series of high-pitched sounds at random intervals is not part of Weber’s test.
Choice B is wrong because holding an activated tuning fork against the client’s mastoid process is part of Rinne’s test, not Weber’s test.
Choice D is wrong because whispering a series of words softly into one ear is not part of Weber’s test.
