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.

3. What is the term for the body's ability to defend itself against specific invading agents such as bacteria, toxins, viruses, and foreign bodies?

• A. Hormones
• B. Secretion
• C. Immunity
• D. Glands

Correct answer: C

Rationale: The correct answer is C: Immunity. Immunity refers to the body's ability to protect itself against specific invading agents like bacteria, toxins, viruses, and foreign bodies by recognizing and destroying them. It is a crucial defense mechanism that helps maintain health and prevent infections and diseases. Choices A, B, and D are incorrect because hormones are chemical messengers, secretion is the process of releasing substances, and glands are organs that produce and release substances, none of which specifically relate to the body's defense against invading agents.

4. If a patient's blood pressure is 150/96, what is his pulse pressure?

• A. 54
• B. 96
• C. 150
• D. 246

Correct answer: A

Rationale: Pulse pressure is calculated by subtracting the diastolic pressure from the systolic pressure. In this case, the systolic pressure is 150 and the diastolic pressure is 96. Therefore, the pulse pressure is 150 - 96 = 54. Pulse pressure represents the force generated by the heart with each contraction and is an important indicator of cardiovascular health.

5. A client with active tuberculosis is prescribed isoniazid, rifampin, pyrazinamide, and ethambutol. Which statement by the client indicates an understanding of the teaching?

• A. I can substitute one medication for another if I run out because they all fight infection.
• B. I will wash my hands each time I cough.
• C. I am glad I don't have to have any more sputum specimens.
• D. I don't need to worry about where I go once I start taking my medications.

Correct answer: B

Rationale: The correct statement indicating understanding of tuberculosis medication regimen is 'I will wash my hands each time I cough.' This statement shows knowledge of infection control practices to prevent the spread of tuberculosis. Washing hands after coughing helps in reducing the transmission of the disease to others. The other options are incorrect. Option A is incorrect as each medication in the regimen has a specific role, and substituting one for another can compromise the effectiveness of treatment. Option C is incorrect as obtaining sputum specimens is essential for monitoring treatment response. Option D is incorrect as the client should still adhere to infection control measures and avoid exposing others to tuberculosis.
