A peak flow meter
- A. is used to administer inhaled medications in dry powder form
- B. gives feedback to determine whether the client is developing asthma symptoms
- C. is used to identify specific allergy trigger agents
- D. can only be used by a respiratory therapist or nurse with special education
Correct Answer: B
Rationale: The correct answer is B because a peak flow meter is used to monitor and measure the peak expiratory flow rate, which helps determine if the client is developing asthma symptoms such as airway constriction. It provides feedback on the client's lung function, helping to assess asthma control and guide treatment. Choices A, C, and D are incorrect because a peak flow meter is not used for administering medications, identifying allergy triggers, or limited to specific healthcare professionals.

Which type of exercise is most beneficial for older adults to prevent falls and maintain balance?
- A. Swimming
- B. Weight training
- C. Yoga and tai chi
- D. Running
Correct Answer: C
Rationale: The correct answer is C: Yoga and tai chi. These exercises focus on balance, flexibility, and strength, which are crucial for preventing falls in older adults. Yoga and tai chi also promote mindfulness and body awareness, further enhancing balance and coordination. Swimming (choice A) is beneficial for overall fitness but may not specifically target balance and fall prevention. Weight training (choice B) is important for muscle strength but may not address balance and flexibility adequately. Running (choice D) is high-impact and may actually increase the risk of falls for older adults.
Decreased functioning of which physical structure is likely to result in decreased metabolism in older adults?
- A. Kidney
- B. Thyroid gland
- C. Brain
- D. Skeleton
Correct Answer: B
Rationale: The correct answer is B: Thyroid gland. The thyroid gland produces hormones that regulate metabolism. In older adults, decreased thyroid function, known as hypothyroidism, can lead to a decrease in metabolism. This can result in symptoms such as fatigue, weight gain, and slowed heart rate.
A: Kidney - While the kidneys play a role in filtering waste and maintaining fluid balance, decreased kidney function typically does not directly impact metabolism.
C: Brain - The brain plays a crucial role in regulating various bodily functions, but it does not directly control metabolism.
D: Skeleton - The skeleton provides structural support and protects organs but does not directly influence metabolism.
How does sarcopenia impact functional independence in older adults?
- A. It leads to increased body fat and reduced muscle mass, hindering mobility.
- B. It results in diminished lung capacity, reducing the ability to perform daily activities.
- C. It causes joint stiffness, leading to pain and limited range of motion.
- D. It significantly affects balance and mobility, increasing the risk of falls.
Correct Answer: D
Rationale: The correct answer is D because sarcopenia, which is the age-related loss of muscle mass and strength, directly impacts balance and mobility in older adults. Muscle weakness from sarcopenia reduces stability and coordination, increasing the risk of falls. This affects functional independence as it limits the ability to perform daily activities safely. Choices A, B, and C are incorrect as sarcopenia primarily affects muscle mass and strength, not body fat, lung capacity, or joint stiffness.
Identify the correct statement describing the abuse of elderly persons in the United States.
- A. Elder abuse is the most often reported form of domestic violence
- B. Statistically, neglect is the most common form of elder abuse
- C. Most cases of elder abuse are reported to the proper authorities
- D. Healthcare practitioners are only mandated to report verified, not suspected, cases of elder abuse
Correct Answer: B
Rationale: The correct answer is B: Statistically, neglect is the most common form of elder abuse. Neglect involves the failure to provide necessary care or assistance to an elderly person, making it a prevalent form of elder abuse. This is supported by research and studies on elder abuse cases.
A is incorrect because elder abuse is often underreported compared to other forms of domestic violence.
C is incorrect as many cases of elder abuse go unreported due to various reasons such as fear, shame, or lack of awareness.
D is incorrect as healthcare practitioners are mandated to report any suspected cases of elder abuse, not just verified cases, to protect the well-being of the elderly.
The nurse is performing an assessment on an older adult client. What assessment data would indicate a potential complication associated with the skin of this client?
- A. Crusting
- B. Wrinkling
- C. Thinning/loss of elasticity of skin
- D. Crusting
Correct Answer: A
Rationale: The correct answer is A: Crusting. In older adults, crusting on the skin can indicate a potential complication such as infection, dermatitis, or impaired wound healing. Crusting may result from dryness, scratching, or poor circulation. It is essential for the nurse to assess and address the underlying cause promptly to prevent further complications.
B: Wrinkling is a normal part of aging and not necessarily indicative of a complication unless it is severe and associated with other symptoms.
C: Thinning/loss of elasticity of skin is a common age-related change and may not always indicate a complication unless it is excessive.
D: Crusting is a duplicate answer.
