A nurse is reinforcing teaching with a client who is receiving morphine via a patient-controlled analgesia (PCA) infusion device. Which of the following statements by the client indicates an understanding of the teaching?
"I'll be careful about pushing the button so I don't get an overdose."
"I should tell the nurse if I can't control my pain with this device."
"I will ask my family to push the dose button when I am asleep."
"I should only use the device when it's absolutely necessary."
The Correct Answer is B
A. While it's important to use the PCA device responsibly, the device is designed to prevent overdose. The client should not be overly concerned about this.
B. This statement demonstrates an understanding of the PCA device's limitations and the importance of seeking additional pain relief if needed. The nurse is responsible for adjusting the medication dosage or providing alternative pain relief methods if the PCA device is not adequately controlling the client's pain.
C. Only the client should administer the medication through the PCA device. Family members or other individuals should not be allowed to use the device.
D. The PCA device is designed to provide pain relief as needed. The client should use it whenever they experience pain, rather than waiting until the pain becomes severe.

Correct Answer is B
Explanation
A. With aging, the tympanic membranes (eardrums) typically become thinner and less flexible, which can affect hearing. Therefore, this choice does not reflect the physiological changes that occur.
B. One of the most common changes in hearing as people age is presbycusis, which often leads to a decreased ability to hear high-frequency sounds. This loss can significantly impact communication and quality of life for older adults.
C. Tinnitus, which is the perception of ringing or buzzing in the ears, often does not decrease with age. In fact, many older adults experience increased tinnitus or persistent tinnitus due to age-related hearing loss or other factors, making this choice incorrect.
D. This is not typically accurate. Older adults often have an increased build-up of ear wax (cerumen) due to changes in ear canal structure and gland function. This can lead to blockages that affect hearing, so this choice does not represent a physiological change commonly observed in older adults.
