The nurse should identify the following action as an indication of correct use of a cane:
2. The cane is held on the patient's stronger side and is advanced 4-12 inches (10-30 cm).
This is the correct technique for using a cane. By holding the cane on the stronger side, it provides support and stability to the patient. Advancing the cane 4-12 inches (10-30 cm) ahead helps with balance and reduces the risk of falls.
This technique helps distribute weight and provides support on the stronger side. The weaker leg should be moved forward until it is even with the stronger leg while advancing the cane. Supporting weight on the weaker leg or advancing the stronger leg ahead of the cane may result in imbalance and increase the risk of falls. Proper distribution of weight and coordinated movements ensure effective use of the cane for stability and mobility.

Correct cane usage involves even weight distribution between the feet and the cane, holding the cane on the stronger side, moving the weaker leg forward parallel to the cane as the cane advances, and ensuring that the weaker leg moves in time with the cane.
Explanation:In evaluating a client's use of a cane, a nurse should identify several actions as indications of correct use. These include the patient standing with weight evenly distributed between the feet and the cane, which indicates proper balancing for stability. Another correct action is the holding of the cane on the patient's stronger side, advancing it about 4-12 inches (10-30 cm). This provides additional support for walking and minimizes strain on the leg.
The proper gait when using a cane involves supporting weight on the stronger leg and advancing the weaker leg forward parallel to the cane. This helps in stability and proper weight distribution. Conversely, supporting weight on the weaker leg and advancing the stronger leg forward indicates incorrect usage and could lead to falls or injury. Finally, the correct timing of movement is important: the weaker leg should move forward even with the stronger leg simultaneously with the advancement of the cane. This creates a smooth, rhythmical walking pattern, reducing the risk of falls and improving balance.

If a patient is concerned about their ACTH levels or has symptoms of Cushing's syndrome, it is important to consult with their healthcare provider for further evaluation and management.

The nursing instructor is teaching about urinary incontinence. She lists the three most common types to be urge, stress, and mixed incontinence. Which of these is caused by inadequate urinary sphincter function?
a. urge
b. stress
c. mixed
d. all of the above
Stress incontinence is the type of urinary incontinence caused by inadequate urinary sphincter function. Option B. Stress is correct choice.
It occurs when there is a loss of support to the urethra or weakness in the muscles that control the bladder and urethra. This can result in the involuntary leakage of urine during activities that increase abdominal pressure, such as coughing, sneezing, laughing, or lifting heavy objects. The inadequate function of the urinary sphincter is primarily responsible for the inability to control urine flow in cases of stress incontinence.
On the other hand, urge incontinence is caused by involuntary contractions or spasms of the bladder muscles, leading to a sudden and strong urge to urinate, often followed by leakage. Mixed incontinence refers to a combination of stress and urge incontinence, where both inadequate sphincter function and bladder muscle spasms contribute to the symptoms.
