Anatomy

1. The fatty sheath that insulates some nerve fibers and speeds up signal transmission is called the:

Correct answer: A

Rationale: The correct answer is A: Myelin sheath. The myelin sheath is a fatty layer that surrounds and insulates certain nerve fibers. It acts as an electrical insulator, speeding up the transmission of nerve impulses along the axon. This insulation helps to prevent signal loss or interference, allowing for faster and more efficient communication between neurons. The other options, B: Dura mater, C: Pia mater, and D: Arachnoid mater, are all layers of the meninges that protect the brain and spinal cord, but they do not play a role in insulating nerve fibers for signal transmission like the myelin sheath does.

2. She wants to ensure that every task is carried out as planned. Which of the following tasks is

Correct answer: C

Rationale: The correct answer is C because evaluating the credentials of all nursing staff is essential to ensuring that the right individuals are in place to carry out tasks effectively. This task directly contributes to maintaining a high standard of performance and ensuring that the team is qualified for their roles. In contrast, the other options focus on policies, reviews, and schedules, which are important but do not directly address the qualifications and capabilities of the staff responsible for task execution.

3. The hormone responsible for regulating blood sugar levels is produced by the:

Correct answer: C

Rationale: The correct answer is C: Pancreas. The hormone responsible for regulating blood sugar levels is insulin, which is produced by the pancreas. Insulin helps to lower blood sugar levels by allowing cells to take in glucose from the bloodstream. The pituitary gland (A) is known for producing various hormones that regulate other endocrine glands, while the thyroid gland (B) produces hormones that regulate metabolism. The adrenal glands (D) produce hormones such as cortisol and adrenaline, but they are not primarily responsible for regulating blood sugar levels.

4. Chyle, a milky white fluid, is transported by lymphatic vessels from the:

Correct answer: B

Rationale: The correct answer is B: Intestines. Chyle is a milky white fluid that is formed in the small intestine during digestion, mainly from the absorption of dietary fats. It is rich in fats and lymphocytes. Lymphatic vessels in the intestines, called lacteals, absorb the chyle and transport it through the lymphatic system. Chyle eventually enters the bloodstream via the thoracic duct. The lungs are responsible for gas exchange, not the transport of chyle. The kidneys are involved in filtering blood and producing urine. The skin is the body's largest organ responsible for protection, temperature regulation, and sensation, but it is not involved in transporting chyle.

5. Which pattern of nursing care involves the care given by a group of paraprofessional workers

Correct answer: A

Rationale: The correct answer is A: 'Case method.' The case method of nursing care involves the care provided by a group of paraprofessional workers, such as nursing assistants or aides, under the supervision of professional nurses. In this model, the nursing team works together to deliver care to a group of patients based on their specific needs and conditions. This method allows for efficient and coordinated care delivery, with each member of the team playing a crucial role in meeting the patients' healthcare needs. It is important for nurses to effectively delegate tasks and supervise paraprofessional workers in the case method model to ensure high-quality care and patient safety.

6. Define power in physics.

Correct answer: b

Rationale: Power is the rate at which work is done or energy is transferred or converted.
