A nurse is admitting a client who is dehydrated. Which BUN level should the nurse expect the client to have upon admission (Normal BUN 10-20)?

165 mg/dL

35 mg/dL

10 mg/dL

31 mg/dL

Answer and Explanation

The Correct Answer is B

A: A BUN level of 165 mg/dL is extremely high and suggests severe dehydration or possible renal failure. This level is far above the normal range and indicates a critical condition.

B: A BUN level of 35 mg/dL is elevated and consistent with dehydration. Dehydration causes the kidneys to reabsorb more water, leading to higher concentrations of urea in the blood.

C: A BUN level of 10 mg/dL is within the normal range and does not indicate dehydration. This level suggests normal kidney function and hydration status.

D: A BUN level of 31 mg/dL is elevated and suggests dehydration. While not as high as 165 mg/dL, it still indicates that the patient is dehydrated and requires intervention.

Correct Answer is B

Explanation

A: Auscultation, or listening for air injected into the tube, is not a reliable method for verifying feeding tube placement. It can lead to false positives and does not confirm the tube’s location accurately.

B: X-ray is the gold standard for verifying feeding tube placement. It provides a clear image of the tube’s position, ensuring it is correctly placed in the stomach or small intestine, reducing the risk of complications.

C: Aspiration of contents can help verify placement by checking the appearance and pH of the aspirate. However, it is not as definitive as an X-ray and can sometimes be inconclusive.

D: pH testing of aspirate can indicate whether the tube is in the stomach (acidic pH) or intestines (less acidic). While useful, it is not as reliable as an X-ray for confirming placement.

A. Debride the wound. B. Manage drainage from the wound. C. Document the wound. D. Monitor the wound.

Correct Answer is A

Explanation

A: Debriding the wound is the next step for a black (necrotic) pressure ulcer. Removing the dead tissue is essential to promote healing and prevent infection.

B: Managing drainage is important for wound care but is not the immediate next step for a necrotic ulcer.

C: Documenting the wound is necessary but does not address the need for debridement.

D: Monitoring the wound is important, but active intervention (debridement) is required for a necrotic ulcer to promote healing.
