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 D

Explanation

A: Encouraging the client to consume a high-protein diet is beneficial for overall health and recovery but does not directly prevent the transmission of infection.

B: Changing the client’s bed linens each day is good practice for maintaining cleanliness but is not the most critical strategy for preventing infection transmission.

C: Placing the client in a room with positive-pressure airflow is used for protecting immunocompromised patients from outside infections, not for preventing the spread of infection from the client.

D: Performing hand hygiene before, during, and after direct contact with the client is the most effective strategy for preventing the transmission of infection. Proper hand hygiene is crucial in breaking the chain of infection and protecting both the client and healthcare providers.

A. Check the client’s skin every 8 hours for signs of breakdown. B. Clean the client’s skin and perineum with hot water after each episode of incontinence. C. Apply a moisture barrier ointment to the client’s skin. D. Request a prescription for the insertion of an indwelling urinary catheter.

Correct Answer is C

Explanation

A: Checking the client’s skin every 8 hours is not frequent enough to prevent skin breakdown in a client with urinary incontinence. More frequent checks are necessary to identify and address any issues promptly.

B: Cleaning the client’s skin and perineum with hot water can cause skin irritation and dryness. It is better to use lukewarm water and gentle cleansers to maintain skin integrity.

C: Applying a moisture barrier ointment to the client’s skin is an effective way to prevent skin breakdown. The ointment creates a protective barrier that helps keep moisture away from the skin, reducing the risk of irritation and breakdown.

D: Requesting a prescription for the insertion of an indwelling urinary catheter is not the best first-line intervention for preventing skin breakdown. Catheters carry a risk of infection and should be used only when absolutely necessary.
