A charge nurse is teaching a newly licensed nurse about the administration of total parenteral nutrition. Which of the following statements should the charge nurse include?

"You will need to change the IV dressing site once per week."

"You will need to warm the solution in the microwave before administration."

"You will need to weigh the client twice per week."

"You will need to monitor the client's electrolytes daily."

Answer and Explanation

The Correct Answer is D

Rationale:

A. "You will need to change the IV dressing site once per week.": Central line dressings for TPN are typically changed every 48–72 hours for gauze or every 5–7 days for transparent dressings, or sooner if the dressing becomes damp, loose, or soiled, to reduce infection risk.

B. "You will need to warm the solution in the microwave before administration.": TPN solutions should never be microwaved due to the risk of uneven heating and nutrient degradation. They should be administered at room temperature.

C. "You will need to weigh the client twice per week.": Clients receiving TPN require daily weights to monitor fluid balance, nutritional status, and detect fluid retention or dehydration promptly. Twice-weekly measurements are insufficient for close monitoring.

D. "You will need to monitor the client's electrolytes daily.": TPN can cause rapid changes in fluid and electrolyte balance, so daily electrolyte monitoring allows timely adjustments to prevent complications such as hypo- or hypernatremia, hypokalemia, and metabolic imbalances.

Correct Answer is A

Explanation

Rationale:

A. "The nurse will ask you to remove any transdermal patches prior to the procedure.": Some transdermal patches contain metallic components that can overheat during an MRI, posing a burn risk. Removing them prevents injury and ensures safety in the strong magnetic field.

B. "The nurse will ask you to wear protective eyewear during this procedure.": Protective eyewear is not necessary for MRI scans, as there is no exposure to bright light or flying debris. This precaution applies more to procedures involving lasers or potential eye hazards.

C. "You should not have this procedure if you are allergic to iodine.": Iodine allergies are a concern with certain CT scans using iodinated contrast, not standard MRIs. MRI contrast agents typically contain gadolinium, which has a different allergy profile.

D. "You should not have this procedure if you have a tattoo.": Tattoos generally do not contraindicate MRI, although some with metallic ink may cause mild skin irritation. This is rare and does not usually prevent the procedure from being performed.

A. "Keep objects away from your center of gravity while lifting." B. "Keep your feet together to provide a tight base of support." C. "Tighten abdominal muscles to improve balance." D. "Bend at the waist when lifting objects from the floor."

Correct Answer is C

Explanation

A. "Keep objects away from your center of gravity while lifting.": Lifting objects away from the body increases strain on the back and risks injury. Objects should be kept close to the body to reduce musculoskeletal stress.

B. "Keep your feet together to provide a tight base of support.": A narrow stance decreases stability and increases the risk of losing balance. Proper lifting requires a wide, stable base with feet shoulder-width apart.

C. "Tighten abdominal muscles to improve balance.": Engaging the core stabilizes the spine, maintains proper posture, and helps prevent back injuries during lifting. This is an important ergonomic technique.

D. "Bend at the waist when lifting objects from the floor.": Bending at the waist places excessive strain on the lower back. Proper lifting technique involves bending at the knees and hips while keeping the back straight.
