All of the following nursing actions except____________ will help maintain safety for the elderly.
- A. Modify environment to reduce obstacles and barriers to ambulation
- B. Provide for consistent, regular checks of clients' ambulation abilities
- C. Orient to new surroundings and repeat frequently as needed
- D. Promote independence without assistance to all clients
Correct Answer: D
Rationale: The correct answer is D because promoting independence without assistance to all clients may not always maintain safety for the elderly. Elderly individuals may require some level of assistance for certain activities to prevent falls or other safety risks. Providing assistance when needed is crucial for ensuring their safety.
A: Modifying the environment to reduce obstacles and barriers to ambulation helps prevent falls.
B: Consistent checks of ambulation abilities ensure early detection of any decline in mobility.
C: Orienting to new surroundings and repeating as needed helps prevent confusion and disorientation.

In managing frailty, what is the most important factor for improving strength and overall function in older adults?
- A. High-protein diet
- B. Medication management
- C. Regular strength training exercises
- D. Limiting physical activity to prevent injury
Correct Answer: C
Rationale: Certainly! Regular strength training exercises are crucial for improving strength and overall function in older adults with frailty. Strength training helps build muscle mass, improve balance, and increase mobility, leading to enhanced functional abilities. It also helps prevent falls and maintain independence. High-protein diet (A) supports muscle health but alone is not sufficient. Medication management (B) is important but not the primary factor for physical function. Limiting physical activity (D) can worsen frailty by causing deconditioning and loss of muscle strength.
A 78 yr old female presents to the ED with complaints of nausea and sudden onset shortness of breath. The initial workup includes ____________.
- A. upper endoscopy
- B. CT of the head
- C. liver function studies
- D. EKG and serial enzymes for determination of an MI
Correct Answer: D
Rationale: The correct answer is D, EKG and serial enzymes for determination of an MI. In this scenario, the patient's symptoms of nausea and sudden onset shortness of breath raise concern for a possible myocardial infarction (MI). Conducting an EKG and serial enzymes helps in diagnosing an MI by assessing for cardiac ischemia or injury. Upper endoscopy (choice A) is not indicated for these symptoms. A CT of the head (choice B) is unnecessary as the symptoms are suggestive of a cardiac issue, not a neurological one. Liver function studies (choice C) do not align with the presenting symptoms and are not a priority in this acute setting. Conducting an EKG and serial enzymes is the most appropriate initial workup to assess for a possible MI in this elderly patient with concerning symptoms.
What is the primary factor contributing to medication nonadherence in older adults?
- A. Lack of health literacy
- B. High cost of medications
- C. Limited access to healthcare providers
- D. Complicated medication regimens
Correct Answer: D
Rationale: The correct answer is D: Complicated medication regimens. Older adults often have multiple medical conditions requiring several medications, leading to confusion and difficulty in following complex regimens. This complexity increases the likelihood of medication nonadherence. Lack of health literacy (A) may contribute but is not the primary factor. High cost of medications (B) and limited access to healthcare providers (C) are important barriers, but they are not as directly linked to nonadherence as the complexity of medication regimens.
Which of the following best describes the pathophysiology of delirium in older adults?
- A. It is caused by an acute inflammatory response to infection.
- B. It results from reversible metabolic changes, such as electrolyte imbalances.
- C. It is primarily related to neurodegeneration in the brain.
- D. It is caused by chronic stress responses and cortisol overproduction.
Correct Answer: B
Rationale: The correct answer is B: Delirium in older adults results from reversible metabolic changes, such as electrolyte imbalances. Delirium is a multifactorial condition often triggered by physiological imbalances, including electrolyte disturbances. These imbalances can disrupt normal brain function, leading to confusion and cognitive impairment. Other choices are incorrect: A is more typical of sepsis, C is more associated with conditions like dementia, and D is not a primary cause of delirium.
What is the most common type of vision impairment in older adults?
- A. Cataracts
- B. Glaucoma
- C. Age-related macular degeneration (AMD)
- D. Diabetic retinopathy
Correct Answer: A
Rationale: The correct answer is A: Cataracts. Cataracts are the most common type of vision impairment in older adults due to the clouding of the eye's lens. As people age, proteins in the lens can clump together, leading to vision issues. Glaucoma (B) is characterized by damage to the optic nerve, AMD (C) affects the macula in the retina, and diabetic retinopathy (D) is a complication of diabetes affecting blood vessels in the retina. However, cataracts are the primary cause of vision impairment in older adults due to the natural aging process of the eye.
