A nurse is caring for a client who is postoperative following a bowel surgery and has an NG tube connected to low intermittent suction. Which of the following assessment findings should indicate to the nurse that the NG tube might not be functioning properly?

- A: An INR of 1.1 is within the normal range, indicating normal blood clotting ability, which is essential for wound healing. A normal INR does not pose a risk for delayed wound healing.
- B: Hyperemesis can lead to dehydration and malnutrition, both of which are detrimental to wound healing. Dehydration reduces blood volume and flow, impairing the delivery of oxygen and nutrients to the wound site, while malnutrition can weaken the immune response and the formation of new tissue.
- C: An HbA1C level of 5.6% is at the high end of the normal range and does not typically indicate diabetes or impaired glucose control, which are risk factors for delayed wound healing.
- D: While uncontrolled pain can be a concern for patient comfort and may indirectly affect wound healing by reducing mobility, it is not a direct risk factor for delayed wound healing like hyperemesis is.

- Choice A: The recommended hepatitis vaccine series is not a series of four. The Advisory Committee on Immunization Practices (ACIP) recommends a three-dose series for hepatitis B vaccination.
- Choice B: Hepatitis B is not typically transmitted by contaminated food. It is primarily spread through direct contact with infectious blood, semen, or other body fluids.
- Choice C: While there is some evidence suggesting a link between chronic hepatitis C infection and an increased risk of renal cell carcinoma, the statement is not universally accepted as fact and more research is needed to establish a definitive connection.
- Choice D: Individuals with a history of hepatitis B or C are generally ineligible to donate blood due to the risk of transmission of these bloodborne viruses.
