1. Skeletal muscles are attached to bones by tough connective tissues called

A. Ligaments
B. Tendons
C. Cartilage
D. Fascia

Correct answer: B

Rationale: The correct answer is B: Tendons. Skeletal muscles are connected to bones by tendons, which are tough connective tissues that transmit the force generated by the muscle to the bone, allowing movement. Ligaments (A) connect bone to bone and provide stability to joints. Cartilage (C) is a smooth, firm tissue that covers the surface of bones at joints, reducing friction and absorbing shock. Fascia (D) is a connective tissue that surrounds muscles and other structures, providing support and protection.

2. What are isotopes?

A. Atoms of the same element with different numbers of protons.
B. Atoms of the same element with different numbers of neutrons.
C. Atoms of different elements with the same number of protons.
D. Atoms of different elements with the same number of electrons.

Correct answer: B

Rationale: Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons. This means that isotopes have the same atomic number (Z) but different mass numbers (A). For example, carbon-12 (Â¹Â²C), carbon-13 (Â¹Â³C), and carbon-14 (Â¹â´C) are all isotopes of carbon. They all have six protons in their nuclei, but they have different numbers of neutrons: carbon-12 has six neutrons, carbon-13 has seven neutrons, and carbon-14 has eight neutrons.

3. Which orbital can hold a maximum of 8 electrons?

A. s orbital
B. p orbital
C. d orbital
D. f orbital

Correct answer: C

Rationale: d orbital - Each d orbital can hold a maximum of 2 electrons, and there are 5 d orbitals, totaling 10 possible electrons.

4. 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.

5. Bile, a digestive juice, is produced by which organ?

A. Stomach
B. Liver
C. Pancreas
D. Small intestine

Correct answer: B

Rationale: The correct answer is B: Liver. Bile is a digestive juice that is produced by the liver and stored in the gallbladder. It plays a crucial role in the digestion and absorption of fats in the small intestine. The stomach primarily produces gastric juices that aid in breaking down food, while the pancreas secretes digestive enzymes and bicarbonate into the small intestine. The small intestine is responsible for the absorption of nutrients. Therefore, the liver is the organ that produces bile, making it the correct answer to this question.

6. Which vitamin requires intrinsic factor from the stomach for proper absorption?

A. Vitamin A
B. Vitamin C
C. Vitamin D
D. Vitamin B12

Correct answer: D

Rationale: The correct answer is D, Vitamin B12. Vitamin B12 requires intrinsic factor, a glycoprotein produced by the parietal cells in the stomach, for proper absorption in the small intestine. Intrinsic factor binds to B12 and facilitates its absorption in the ileum. Without intrinsic factor, the body cannot effectively absorb Vitamin B12, leading to deficiencies and various health issues. Vitamins A, C, and D do not require intrinsic factor for absorption and have different mechanisms for uptake and utilization within the body.
