Nursing Elites

1. When treating a patient for a fungal infection with IV amphotericin B, what should the nurse consistently monitor the patient's levels of to prevent drug discomfort?

• A. sodium
• B. hemoglobin
• C. calcium
• D. leukocytes

Correct answer: C

Rationale: When a patient is being treated with IV amphotericin B for a fungal infection, it is crucial to monitor the patient's calcium levels consistently. IV amphotericin B can cause hypokalemia, hypomagnesemia, and most notably, hypocalcemia. Monitoring calcium levels helps prevent drug-related discomfort and adverse effects. Sodium (Choice A), hemoglobin (Choice B), and leukocytes (Choice D) are not the primary parameters to monitor specifically for drug discomfort related to amphotericin B. Therefore, they are incorrect choices.

2. What is the best way to prevent transmission of infectious agents?

• A. Take antibiotics daily
• B. Call the practitioner for herbal supplements
• C. Wash hands
• D. Avoid public areas as much as possible

Correct answer: C

Rationale: The correct answer is C: Wash hands. Washing hands is the most effective way to prevent the transmission of infectious agents. Antibiotics are not effective in preventing infections, and their overuse can lead to antibiotic resistance. Calling a practitioner for herbal supplements is not a primary method for preventing the transmission of infectious agents. Avoiding public areas entirely is impractical and not as effective as proper hand hygiene.

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. Which of the following mediators of inflammation causes increased capillary permeability and pain?

• A. Serotonin
• B. Histamine
• C. Bradykinin
• D. Nitric oxide

Correct answer: C

Rationale: Bradykinin is the correct answer. It is a potent mediator of inflammation that causes increased capillary permeability and is responsible for the pain associated with inflammation. Serotonin and histamine are also mediators of inflammation, but they are not primarily known for increasing capillary permeability or inducing pain. Nitric oxide is involved in various physiological processes but is not a primary mediator of inflammation that causes increased capillary permeability and pain.

5. How are antibodies produced?

• A. B cells
• B. T cells
• C. Helper cells
• D. Memory cells

Correct answer: A

Rationale: Antibodies are produced by B cells. B cells are specialized white blood cells that generate antibodies as part of the immune response. B cells differentiate into plasma cells that secrete antibodies. T cells play a role in cell-mediated immunity, not antibody production. Helper cells, or helper T cells, assist in activating B cells but do not directly produce antibodies. Memory cells store information about previous infections but do not actively produce antibodies.
