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: Pulling the auricle upward and outward is the correct technique for adults and children over 3 years old, not for a 2-year-old child.

B: Pulling the auricle down and back is the correct technique for straightening the ear canal in children under 3 years old. This allows for proper administration of the eardrops.

C: Sitting the child up to insert a cotton ball into the innermost ear canal is not appropriate. Cotton balls should not be inserted deeply into the ear canal.

D: Sitting the child up for 2 to 3 minutes after instilling drops is not necessary. The child should remain in a position that allows the drops to stay in the ear canal for the prescribed time.

A. Uses a microwave for cooking. B. Handrails are present in the bathroom. C. Electrical cords are placed along the walls. D. Scatter rugs are present in the kitchen.

Correct Answer is D

Explanation

A: Using a microwave for cooking is generally safe for older adults with decreased vision. Microwaves are user-friendly and reduce the risk of burns or fires compared to stovetops. However, it is important to ensure that the microwave is at an accessible height and that the user can read the controls or has them memorized.

B: Handrails in the bathroom are a safety feature, not a risk. They provide support and stability, reducing the likelihood of falls, which is crucial for individuals with decreased vision. Properly installed handrails can significantly enhance bathroom safety.

C: Electrical cords placed along the walls are typically not a safety risk if they are secured properly and do not create tripping hazards. It is important to ensure that cords are not loose or crossing walkways where they could cause falls.

D: Scatter rugs in the kitchen are a significant safety risk for older adults with decreased vision. These rugs can easily cause tripping and falling, especially if they are not secured with non-slip backing. Removing scatter rugs or securing them properly is essential to prevent accidents.
