During an admission assessment, the patient reports that he takes vitamin E supplements twice a day . The nurse should
explain that taking vitamin E supplements twice a day
1) ensures healthy vision.
2) can lead to toxicity .
3) strengthens the immune system.
4) helps maintain body tissues.
Answer:
2) can lead to toxicity .
Rationale:
Vitamins are critical in building and maintaining body tissues, supporting the immune system to fight infection, and ensuring healthy vision. However when
fat-soluble vitamins, such as vitamins A, D, E, and K, are supplemented in large doses, toxicity may occur .
The nurse is preparing an enteral feeding for a patient who will be receiving intermittent feedings via nasogastric tube for
the first time. The patient is conscious. Which of the following is the priority intervention before administering this feeding?
1) Observe whether the patient can speak.
2) Inject air into the feeding tube while auscultating the stomach.
3) Aspirate stomach contents and measure residual volume.
4) Obtain an x-ray of the chest and abdomen.
Answer:
4) Obtain an x-ray of the chest and abdomen.
Rationale:
It is essential to verify that the NG tube is in the stomach and not the airway . The only reliable method among these four is to obtain an x-ray of the chest
and abdomen. For subsequent feedings, however , it is not practical to obtain an x-ray each time, and presence of formula in the stomach complicates the
pH readings. Therefore, the nurse should use a combination of bedside techniques, including observing appearance and measuring the amount of gastric
residual volume, asking the patient to speak, and injecting air ("whoosh" test) while auscultating the stomach.
The head of the bed of a patient who is receiving enteral feedings is elevated to 45 degrees. Which complication
associated with enteral feedings does this intervention help prevent?
1) Aspiration
2) Diarrhea
3) Infection
4) Electrolyte imbalance
Answer:
1) Aspiration
Rationale:
The head of the bed (HOB) should be elevated to at least 30 to 45 degrees during enteral feeding administration to prevent regurgitation and aspiration.
Maintaining an elevated HOB aids in digestion by helping the transit of feeding through the GI tract. Diarrhea, infection, and electrolyte imbalance are all
complications associated with enteral feeding, but cannot be prevented by elevating the head of the bed.
