The nurse is assessing a patient who has been diagnosed with multiple sclerosis (MS).

Which of the following findings is most consistent with this condition?

Muscle atrophy and fasciculations.

Intention tremors and nystagmus.

Flaccid paralysis and areflexia.

Hyperactive reflexes and spasticity.

Answer and Explanation

The Correct Answer is B

Intention tremors and nystagmus. These are some of the common symptoms of multiple sclerosis (MS), a condition that affects the central nervous system and causes communication problems between the brain and the rest of the body. Intention tremors are involuntary shaking movements that occur when a person tries to perform a precise action, such as reaching for an object or writing. Nystagmus is a condition where the eyes make repetitive, uncontrolled movements, often resulting in reduced vision and depth perception.

Choice A is wrong because muscle atrophy and fasciculations are more typical of motor neuron diseases, such as amyotrophic lateral sclerosis (ALS), which affect the nerve cells that control voluntary muscle movements.

Choice C is wrong because flaccid paralysis and areflexia are signs of lower motor neuron lesions, which can be caused by spinal cord injuries, peripheral nerve disorders, or Guillain-Barré syndrome.

Choice D is wrong because hyperactive reflexes and spasticity are signs of upper motor neuron lesions, which can be caused by stroke, traumatic brain injury, or cerebral palsy.

Normal ranges for some of the symptoms mentioned are:.

• Intention tremors: none or minimal.

• Nystagmus: none or minimal.

• Muscle atrophy: none or minimal.

• Fasciculations: none or minimal.

• Flaccid paralysis: none or minimal.

• Areflexia: absent or reduced reflexes.

• Hyperactive reflexes: normal or slightly increased reflexes.

• Spasticity: normal or slightly increased muscle tone.

Correct Answer is B

Explanation

The correct answer is B.

Diphenhydramine.Diphenhydramine is an antihistamine and sedative medication that can causedeliriumin older adults, especially when used in high doses or for a long time.Delirium is a serious change in mental abilities that results in confused thinking and reduced awareness of the surroundings.It can be caused by various factors, such as infections, medications, surgery, or alcohol or drug use or withdrawal.Delirium can have serious consequences, such as increased risk of falls, complications, and death.

Choice A is wrong because acetaminophen is a pain reliever and fever reducer that does not usually cause delirium in older adults.

However, acetaminophen overdose can cause liver damage and altered mental status.

Choice C is wrong because metformin is an oral medication that lowers blood sugar levels in people with type 2 diabetes.

Metformin does not typically cause delirium in older adults.

However, metformin can cause a rare but serious condition called lactic acidosis, which can cause confusion and other symptoms.

Choice D is wrong because lisinopril is an angiotensin-converting enzyme (ACE) inhibitor that lowers blood pressure and prevents heart failure.

Lisinopril does not usually cause delirium in older adults.

However, lisinopril can cause a rare but serious condition called angioedema, which can cause swelling of the face, tongue, or throat and difficulty breathing.

Normal ranges for some relevant laboratory tests are:.

• Albumin: 3.5-5.0 g/dL.

• Potassium: 3.5-5.0 mEq/L.

• Total cholesterol: <200 mg/dL.

• Hemoglobin: 13.5-17.5 g/dL for men; 12.0-15.5 g/dL for women.

A. Physical health and functional status. B. Cognitive conditions and memory loss. C. Living arrangements and social support. D. Hormonal changes and sensory impairments.

Correct Answer is C

Explanation

The correct answer is C.

Living arrangements and social support.

This is because living arrangements and social support are some of the environmental factors that can influence the psychosocial changes in older adults.Psychosocial changes refer to the changes in mental and emotional well-being, social relationships, and roles that occur as people age.Environmental factors are the external conditions or circumstances that affect a person’s life.

Choice A is wrong because physical health and functional status are not environmental factors, but rather biological factors that affect the aging process.Physical health and functional status can influence the psychosocial changes in older adults, but they are not part of the environment.

Choice B is wrong because cognitive conditions and memory loss are also not environmental factors, but rather neurological factors that affect the brain function of older adults.Cognitive conditions and memory loss can also influence the psychosocial changes in older adults, but they are not part of the environment.

Choice D is wrong because hormonal changes and sensory impairments are also not environmental factors, but rather physiological factors that affect the body function of older adults.Hormonal changes and sensory impairments can also influence the psychosocial changes in older adults, but they are not part of the environment.

Living arrangements and social support are environmental factors because they depend on the availability, accessibility, and quality of housing, transportation, community services, family networks, and social interactions that older adults have in their surroundings.Living arrangements and social support can influence the psychosocial changes in older adults by affecting their sense of independence, identity, belonging, security, and satisfaction.

Therefore, living arrangements and social support are some of the environmental factors that can influence the psychosocial changes in older adults.
