A nurse is reinforcing teaching with a client about the prevention of stress injuries. Which of the following instructions should the nurse include?

"Keep your knees in a locked position when standing for prolonged periods."

"Bend at the waist when lifting a heavy object."

"Keep your feet close together when lifting a heavy object."

"When lifting a heavy object, keep it close to your body."

Answer and Explanation

The Correct Answer is D

A.   "Keep your knees in a locked position when standing for prolonged periods." This instruction is incorrect. Keeping knees locked can lead to muscle fatigue and increased risk of injury during prolonged standing.
B.   "Bend at the waist when lifting a heavy object." This instruction is incorrect. Bending at the waist during lifting can strain the lower back and increase the risk of back injuries.
C.   "Keep your feet close together when lifting a heavy object." This instruction is incorrect.
Keeping feet close together can make the base unstable and increase the risk of falling or losing balance during lifting.
D.   "When lifting a heavy object, keep it close to your body." Correct. Keeping the heavy object close to the body while lifting helps reduce strain on the back and minimizes the risk of injury. This technique allows the body's core muscles to better support the weight.

Correct Answer is A, B, C, D

Explanation

Sequence of Actions:

A: Evacuate clients from the area. This is the first and most crucial step to ensure the safety of all individuals in the vicinity of the fire.

B: Pull the lever on the fire alarm box. Once the immediate area is clear of individuals, the next step is to alert the rest of the building by activating the fire alarm system.

C: Close the fire doors on the unit. This action helps to contain the fire and prevent smoke from spreading to other areas, which can be vital in slowing the fire's progress and safeguarding other parts of the building.

D: Use a fire extinguisher to put out the fire. If the fire is small and contained, and the nurse is trained in its use, a fire extinguisher can be used to douse the flames, preventing further damage.

A. Urine specific gravity 1.015 B. Hematocrit 42% C. Urine pH 6.5 D. BUN 5 mg/dL

Correct Answer is D

Explanation

A. A urine specific gravity of 1.015 is within the normal range (1.005–1.030). While fluid volume excess may lead to a lower specific gravity due to urine dilution, this value does not indicate fluid overload and is considered normal.
B. A hematocrit level of 42% is within the normal range for adults (men: 38–50%, women: 35–45%). Hematocrit levels tend to decrease in fluid volume excess due to hemodilution, but this value does not suggest fluid overload.
C. A urine pH of 6.5 is within the normal range (4.5–8.0). Urine pH reflects the acid-base balance rather than fluid status and is not a reliable indicator of fluid volume excess.
D. A BUN level of 5 mg/dL is below the normal range (10–20 mg/dL). In fluid volume excess, the dilution of blood plasma can lead to decreased BUN levels. This low BUN value, in conjunction with clinical symptoms, supports the diagnosis of fluid volume excess.
