1. What is the most common cause of dementia among elderly persons?

• A. Parkinson’s disease
• B. Multiple sclerosis
• C. Amyotrophic lateral sclerosis (Lou Gehrig’s disease)
• D. Alzheimer’s disease

Correct answer: D

Rationale: Alzheimer’s disease is the most common cause of dementia among elderly persons. It is a progressive neurodegenerative disorder that affects memory, thinking, and behavior. While Parkinson’s disease, multiple sclerosis, and amyotrophic lateral sclerosis are serious conditions, they are not typically associated with dementia in the same way Alzheimer’s disease is. Therefore, the correct answer is D.

2. Which instrument is used for auscultation?

• A. Percussion hammer
• B. Audiometer
• C. Stethoscope
• D. Sphygmomanometer

Correct answer: C

Rationale: Auscultation involves listening to internal sounds in the body, such as heart and lung sounds. The instrument used for auscultation is a stethoscope, which allows healthcare providers to listen to these sounds. The percussion hammer is used to elicit sounds on the body, the audiometer is used to measure hearing ability, and the sphygmomanometer is used to measure blood pressure. Therefore, the correct answer is 'Stethoscope.'

3. Which pulse's absence may not be a significant finding when a patient is admitted to the hospital?

• A. Apical
• B. Radial
• C. Pedal
• D. Femoral

Correct answer: C

Rationale: The absence of the pedal pulse may not be significant if the patient has poor peripheral circulation or if the healthcare provider is focused on other pulse points. The pedal pulse is often weaker and may not always be palpable due to various factors, making its absence less concerning in certain situations. However, the absence of other pulses like radial or femoral pulses may indicate more critical conditions and require immediate attention.

4. A client is to receive thrombolytic therapy. Which of the following factors should be recognized as a contraindication to the therapy?

• A. Hip arthroplasty 2 weeks ago
• B. Elevated sedimentation rate
• C. Incident of exercise-induced asthma 1 week ago
• D. Elevated platelet count

Correct answer: A

Rationale: Thrombolytic therapy involves the use of medications to dissolve blood clots. Hip arthroplasty (joint replacement surgery) performed recently is a contraindication to thrombolytic therapy due to the risk of bleeding. Elevated sedimentation rate, exercise-induced asthma, and elevated platelet count are not contraindications to thrombolytic therapy.

5. After 1 week of hospitalization, Mr. Gray develops hypokalemia. Which of the following is the most significant symptom of his disorder?

• A. Lethargy
• B. Increased pulse rate and blood pressure
• C. Muscle weakness
• D. Muscle irritability

Correct answer: C

Rationale: Muscle weakness is a hallmark symptom of hypokalemia. Hypokalemia refers to low levels of potassium in the blood, which can affect muscle function. The decreased potassium levels can lead to muscle weakness, cramping, and even paralysis. These symptoms can impact various muscle groups in the body, making muscle weakness the most significant symptom to monitor and address in patients with hypokalemia.
