1. Which of the following cell types would be the first to aid in killing bacteria to prevent infection in his hand?

• A. Eosinophils
• B. Neutrophils
• C. Leukotrienes
• D. Monocytes

Correct answer: B

Rationale: Neutrophils are the first responders to a bacterial infection. They are phagocytes that engulf and destroy bacteria, playing a crucial role in the early stages of the immune response. Eosinophils are primarily involved in combating parasitic infections and allergic reactions, not bacterial infections. Leukotrienes are signaling molecules that contribute to inflammation and immune responses, but they are not cells. Monocytes are another type of white blood cell that differentiates into macrophages and dendritic cells, playing a role in immune response but not as immediate as neutrophils.

2. Which of the following statements describes an active cellular membrane exchange process?

• A. Sodium moving out of cells and potassium moving into cells
• B. The movement of water from an area of low solute concentration to an area of high solute concentration
• C. The movement of insulin using a protein to travel across the cell membrane
• D. Oxygen moving across the pulmonary capillaries to an area of high carbon dioxide

Correct answer: A

Rationale: The correct answer is A. In active transport, energy is expended to move substances against their concentration gradient. Sodium moving out of cells and potassium moving into cells is an example of active transport because it requires energy to pump these ions across the cell membrane against their concentration gradients. Choices B, C, and D describe passive processes where substances move along their concentration gradients without the input of energy.

3. A family member expresses concern to a nurse about behavioral changes in an elderly aunt. Which would cause the nurse to suspect a cognitive impairment disorder?

• A. Decreased interest in activities that she once enjoyed
• B. Fear of being alone at night
• C. Increased complaints of physical ailments
• D. Problems with preparing a meal or balancing her checkbook

Correct answer: D

Rationale: The correct answer is D. Problems with tasks like meal preparation and balancing a checkbook can indicate cognitive impairment, as these activities involve cognitive functions such as memory, attention, and executive function. Choices A, B, and C are less indicative of cognitive impairment. Decreased interest in activities and increased complaints of physical ailments may be related to other factors like depression, while fear of being alone at night could be due to anxiety or other psychological issues.

4. A 60-year-old male client with a long history of back pain has had little success with a variety of analgesic regimens that his family physician has prescribed. He has recently been diagnosed with a chronic pain disorder. Which teaching points about chronic pain would his physician most likely emphasize to the client?

• A. Chronic pain is often difficult to treat and requires a multimodal approach.
• B. Chronic pain indicates that an underlying injury has not healed properly.
• C. Chronic pain can be managed with a single long-term medication.
• D. Chronic pain is typically less severe than acute pain but lasts longer.

Correct answer: A

Rationale: The correct answer is A. Chronic pain is often complex and challenging to treat, necessitating a multimodal approach that may include medication, physical therapy, and behavioral therapy. Choice B is incorrect because chronic pain does not always indicate that an underlying injury has not healed properly; it can persist even after the initial injury has healed. Choice C is incorrect as chronic pain management usually involves a combination of treatments rather than relying solely on a single long-term medication. Choice D is incorrect because chronic pain is not necessarily less severe than acute pain; it can vary in intensity and duration depending on the individual and underlying condition.

5. A patient who was frequently homeless over the past several years has begun a drug regimen consisting solely of isoniazid (INH). What is this patient's most likely diagnosis?

• A. Active tuberculosis
• B. Latent tuberculosis
• C. Mycobacterium avium complex
• D. Human immunodeficiency virus

Correct answer: A

Rationale: The correct answer is A: Active tuberculosis. Given the patient's history of homelessness and initiation of isoniazid (INH) treatment, the most likely diagnosis is active tuberculosis. Isoniazid is a first-line medication used in the treatment of active tuberculosis. Latent tuberculosis (choice B) would not typically necessitate treatment with isoniazid alone. Mycobacterium avium complex (choice C) is not typically treated with isoniazid alone. Human immunodeficiency virus (choice D) is a risk factor for developing tuberculosis but is not the primary diagnosis in this patient scenario.
