1. When Harry uses team nursing as a care delivery system, he and his team need to assess the

• A. Each patient as listed on the worksheet
• B. Patients who needs least care
• C. Medications and treatments required for all patients
• D. Patients who need the most care

Correct answer: C

Rationale: When Harry uses team nursing as a care delivery system, he and his team need to assess the medications and treatments required for all patients. In team nursing, different team members are responsible for specific aspects of patient care, such as medications and treatments. Assessing the medications and treatments required for all patients ensures that each patient receives appropriate and timely care. This approach helps in coordinating care effectively among team members and prevents errors or omissions in patient treatment. Therefore, option C is the correct answer as it aligns with the principles of team nursing and patient-centered care.

2. Which hormone, produced by the thyroid gland, plays a key role in regulating calcium levels in the blood by promoting calcium release from bones and increasing calcium reabsorption in the kidneys?

• A. Calcitonin
• B. Parathyroid hormone (PTH)
• C. Thyroxine
• D. Insulin

Correct answer: b

Rationale: The correct answer is B: Parathyroid hormone (PTH). PTH is produced by the parathyroid glands, not the thyroid gland. PTH plays a crucial role in regulating calcium levels in the blood by promoting calcium release from bones and increasing calcium reabsorption in the kidneys. This hormone acts in opposition to calcitonin, which is produced by the thyroid gland and works to lower blood calcium levels by promoting calcium deposition into bones. Thyroxine (C) is a thyroid hormone that regulates metabolism, not calcium levels. Insulin (D) is a hormone produced by the pancreas that regulates blood sugar levels, not calcium levels.

3. Which element is used in fire extinguishers to smother flames by displacing oxygen?

• A. Nitrogen
• B. Carbon dioxide
• C. Helium
• D. Argon

Correct answer: B

Rationale: Carbon dioxide extinguishes flames by depriving them of oxygen, preventing the chemical reaction that sustains the fire.

4. What is the difference between active and passive immunity?

• A. Active immunity is short-lived, while passive immunity is long-lasting.
• B. Active immunity involves the body's own immune response, while passive immunity provides immediate protection through antibodies from another source.
• C. Active immunity only protects against bacterial infections, while passive immunity works against both bacteria and viruses.
• D. Passive immunity requires repeated vaccinations, while active immunity is a one-time process.

Correct answer: A

Rationale: The correct answer is A: "Active immunity involves the body's own immune response, while passive immunity provides immediate protection through antibodies from another source." Active immunity is long-lasting because it involves the body's immune system producing memory cells that remember specific pathogens, providing long-term protection. Passive immunity, on the other hand, is short-lived as it involves receiving pre-formed antibodies from an external source, such as through maternal transfer or injection of antibodies, which do not create memory cells for long-lasting protection.

5. Diabetes mellitus is a chronic condition affecting blood sugar control. What is the main type of hormone deficiency associated with type 1 diabetes?

• A. Insulin
• B. Glucagon
• C. Estrogen
• D. Testosterone

Correct answer: A

Rationale: The correct answer is A: "Insulin." In type 1 diabetes, the main type of hormone deficiency is insulin. Insulin is produced by the pancreas and is crucial for regulating blood sugar levels by helping cells absorb glucose. In individuals with type 1 diabetes, the immune system mistakenly attacks and destroys insulin-producing beta cells in the pancreas, leading to a deficiency of insulin. This results in uncontrolled high blood sugar levels, which can have serious consequences if not managed properly. Glucagon, estrogen, and testosterone do not play a primary role in the hormone deficiency associated with type 1 diabetes.

6. Which of the following substances is typically a good conductor of electricity when dissolved in water?

• A. Sugar
• B. Sodium chloride
• C. Olive oil
• D. Oxygen gas

Correct answer: b

Rationale: Ionic compounds like sodium chloride dissociate into ions in water, making the solution conductive. The other choices do not typically conduct electricity in water.
