A nurse is teaching about food choices to a client who has chronic kidney disease and must limit potassium intake. Which of the following choices should the nurse recommend as containing the least potassium?

Choice A reason: The statement that "the spacer should make a whistling sound as you inhale" is not accurate. A whistling sound from the spacer may indicate that the air is being inhaled too quickly and that the user needs to slow down. The purpose of the spacer is to hold the medication released from the inhaler so that it can be inhaled more easily and effectively into the lungs, not to produce a whistling sound.

Choice B reason: Holding one's breath for 10 seconds after inhaling the medication allows for better deposition of the medication in the lungs. This pause gives the medication time to settle in the airways rather than being exhaled too quickly. It is a recommended practice to maximize the effectiveness of the inhaled medication.

Choice C reason: Cleaning the spacer is important to ensure that it works correctly and is free of any residue or debris that could obstruct the medication's path. However, the instruction to "clean the spacer daily with cold water" is incomplete. After rinsing with cold water, the spacer should be left to air dry without rinsing or wiping, as this can create static that affects medication delivery.

Choice D reason: Waiting 30 seconds between puffs is recommended to allow the user to breathe normally for a short period and to prepare for the next dose of medication. This time interval helps to ensure that the second puff is not rushed and that the medication from the first puff has had time to act.

Choice A reason: The client's effort to protect their skin due to increased fragility is a normal part of the aging process. As the skin ages, it becomes thinner and less elastic, making it more susceptible to injuries. The client's proactive approach to skin care is appropriate and does not indicate a need for follow-up.

Choice B reason: The statement "I guess feeling down is just part of aging" suggests a possible misconception about mental health and aging. While it's true that older adults may face various challenges that can affect their mood, persistent feelings of sadness or depression are not a normal part of aging and should be addressed. Mental health is as important as physical health, and feeling down can be a sign of depression, which is treatable at any age.

Choice C reason: Concerns about changes in appearance, such as hair thinning, are common as people age. The client's plan to visit a wig shop indicates they are taking steps to manage these changes and maintain their self-esteem. This does not necessarily indicate a need for follow-up unless the hair loss is sudden or accompanied by other symptoms that could suggest an underlying health issue.

Choice D reason: Missing an appointment but taking the initiative to reschedule shows that the client is actively managing their health care. Regular eye exams are important for older adults as they can help detect vision changes and conditions like glaucoma or cataracts early on. This behavior is responsible and does not indicate a need for follow-up.
