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: The statement “Benefit may outweigh the risk” is more applicable to Pregnancy Risk Category D or X drugs, where there is evidence of risk but potential benefits may justify use in certain situations.

B: Studies showing fetal risk are associated with Pregnancy Risk Category D or X drugs. Category A drugs have not shown fetal risk in controlled studies.

C: Drugs that are contraindicated in pregnant women fall under Pregnancy Risk Category X, where the risks clearly outweigh any potential benefits.

D: Fetal harm is unlikely for Pregnancy Risk Category A drugs. These drugs have been tested in controlled studies and have not shown any risk to the fetus, making them safe for use during pregnancy.

A. Check the display on the PCA pump. B. Obtain an order for another pain medication for breakthrough pain. C. Administer a bolus of medication. D. Encourage the client to administer a demand dose.

Correct Answer is A

Explanation

A: Checking the display on the PCA pump is the first action the nurse should take. This ensures that the pump is functioning correctly and delivering the prescribed dose of medication. It helps identify any technical issues that may be affecting pain control.

B: Obtaining an order for another pain medication for breakthrough pain is important if the current regimen is insufficient. However, this should follow the initial assessment of the PCA pump’s functionality.

C: Administering a bolus of medication may be necessary if the client is experiencing severe pain, but it should be done after confirming that the PCA pump is working correctly.

D: Encouraging the client to administer a demand dose is appropriate if the PCA pump is functioning correctly. However, the nurse should first verify that the pump is delivering the medication as prescribed.
