Anatomy

1. Which protein complex in the sarcomere is responsible for the thick filament?

Correct answer: B

Rationale: The correct answer is B: Myosin. In the sarcomere, the thick filament is composed of myosin protein. Myosin is responsible for the interaction with actin filaments during muscle contraction, forming cross-bridges that generate the force required for muscle movement. Actin (choice A) is a component of the thin filament in the sarcomere, while tropomyosin (choice C) and troponin (choice D) are regulatory proteins associated with muscle contraction but are not part of the thick filament. Understanding the specific components of the sarcomere is crucial for comprehending muscle contraction mechanisms.

2. Identify the antonym of the word "pensive":

Correct answer: A

Rationale: "Joyous" is the opposite of "pensive," which means thoughtful and slightly melancholy.

3. Which element has the highest melting point of any element?

Correct answer: D

Rationale: Diamond's strong covalent bonds between carbon atoms make it incredibly resistant to heat and pressure, giving it the highest melting point.

4. The muscular tube that carries urine from the kidneys to the bladder is called the:

Correct answer: B

Rationale: The correct answer is B: Ureter. The ureter is the muscular tube that carries urine from the kidneys to the bladder. Nephrons are the functional units of the kidneys responsible for filtering blood. The urethra is the tube that carries urine from the bladder out of the body. The glomerulus is a cluster of blood vessels in the nephron that filters blood to form urine. Understanding the functions and locations of these structures is essential for comprehending the urinary system's overall process.

5. Hematopoietic tissue is responsible for

Correct answer: C

Rationale: Hematopoietic tissue is responsible for the production of blood cells. This specialized tissue is found in the bone marrow and is crucial for the continuous generation of red blood cells, white blood cells, and platelets. These blood cells play essential roles in oxygen transport, immune defense, and blood clotting. Building and repairing bone (option A) is primarily the function of osteoblasts and osteoclasts in bone tissue. Supporting and connecting tissues (option B) is the role of connective tissues like tendons and ligaments. Contracting for movement (option D) is the function of muscle tissue. Therefore, the correct answer is C, as hematopoietic tissue specifically focuses on blood cell production.

6. He raised the issue on giving priority to patient needs. Which of the following offers the best

Correct answer: A

Rationale: In the context of the sentence 'He raised the issue on giving priority to patient needs,' the best option is 'Assessing nursing needs and problems' (Option A). This option directly aligns with the idea of prioritizing patient needs by first understanding and assessing the specific nursing needs and problems. By assessing these needs, healthcare providers can tailor their care to address the most pressing concerns of the patients, thus effectively giving priority to patient needs. The other options, such as giving instructions on how nursing care needs are to be met (Option B), controlling and evaluating the delivery of nursing care (Option C), and assigning safe nurse: patient ratio (Option D), do not directly address the importance of assessing patient needs as a crucial step in prioritizing patient care. Therefore, Option A is the most suitable choice in this scenario.
