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.

Correct Answer is ["9"]

Explanation

Step 1: Convert the dosage from mg to mcg. 0.75 mg × 1000 = 750 mcg Result: 750 mcg

Step 2: Determine the number of tablets needed. 750 mcg ÷ 88 mcg/tablet = 8.5227 tablets Result: 8.5227 tablets

Step 3: Round the result to the nearest whole number. 8.5227 tablets rounded to the nearest whole number = 9 tablets Result: 9 tablets

The nurse should administer 9 tablets per dose.
