A nurse is caring for a client who has a prescription for total parental nutrition (TPN).
Which of the following routes of administration should the nurse use?

Albumin is a protein that helps maintain fluid balance in the body by drawing water into the blood vessels. Albumin infusion can increase the blood volume and blood pressure in patients who are in shock due to fluid loss or sepsis.

Choice A is wrong because albumin infusion does not decrease protein levels in the body.

Albumin is a protein itself and adding it to the blood increases the protein concentration.

Choice C is wrong because oxygen saturation of 96% is normal and does not indicate any improvement or deterioration in the patient’s condition.

Choice D is wrong because PaCO2 of 30 mm Hg is low and indicates respiratory alkalosis, which can be caused by hyperventilation, fever, or anxiety. Albumin infusion does not affect PaCO2 levels directly.

The nurse should instruct the client to avoid drinking beverages while sucking on a nicotine lozenge because this can interfere with the absorption of nicotine and reduce its effectiveness. Some possible explanations for the other choices are:

Choice B is wrong because chewing nicotine gum for 10 minutes before spitting it out is too short.

The recommended duration is at least 30 minutes to allow enough nicotine to be released and absorbed through the lining of the mouth.

Choice C is wrong because changing the nicotine patch every other day is not frequent enough.

The patch should be changed daily and applied to a different skin site to prevent irritation and ensure a steady dose of nicotine.

Choice D is wrong because administering 2 sprays of nicotine nasal spray in each nostril with each dose is too much.

The recommended dose is one spray per nostril, up to five times per hour or 40 times per day.

Using too much nasal spray can cause side effects such as nasal irritation, sneezing, coughing, headache, or nausea.
