A nurse is caring for a client who requires an NG tube. After inserting the tube, the nurse tests the pH of the client's aspirate. Which of the following pH levels should the nurse identify as an indication of correct placement of the tube?

A. Constipation
This is correct. Inadequate dietary intake of fiber can lead to constipation. Fiber adds bulk to the stool and promotes regular bowel movements.

B. Memory loss
Memory loss is not typically associated with an inadequate dietary intake of fiber. It is more commonly related to other factors such as aging, medical conditions, or nutritional deficiencies.

C. Brittle hair
Brittle hair is not a direct result of an inadequate intake of dietary fiber. Hair health is influenced by various factors, including overall nutrition and hydration.

D. Bleeding gums
Bleeding gums are not directly linked to an inadequate intake of fiber. However, insufficient vitamin C intake, which is often found in fruits and vegetables (sources of fiber), can contribute to gum problems.

A. Bradycardia:
Explanation: Bradycardia refers to a slow heart rate. In hypervolemia (fluid overload), the heart often compensates by increasing the heart rate rather than causing bradycardia.

B. Oliguria:
Explanation: Oliguria refers to decreased urine output. In hypervolemia, the increased fluid volume can lead to increased urine output rather than oliguria.

C. Peripheral Edema:
Explanation: Peripheral edema, or swelling in the extremities, is a common manifestation of hypervolemia. Excess fluid can accumulate in the tissues.

D. Hypotension:
Explanation: Hypertension, not hypotension, is more commonly associated with hypervolemia. The increased volume of fluid in the blood vessels can lead to elevated blood pressure.
