1. A patient's weight is measured as 75 kilograms. What is their weight in pounds?

• A. 132 pounds
• B. 150 pounds
• C. 110 pounds
• D. 85 pounds

Correct answer: B

Rationale: Rationale: To convert kilograms to pounds, you can use the conversion factor 1 kilogram is approximately equal to 2.20462 pounds. Therefore, to convert 75 kilograms to pounds: 75 kilograms * 2.20462 pounds/kilogram ≈ 165.3475 pounds Rounded to the nearest whole number, the patient's weight of 75 kilograms is approximately 165 pounds. Among the given options, the closest weight in pounds to 165 is 150 pounds (option B).

2. Which of the following is the best guarantee that the patient’s priority needs are met?

• A. Checking with the relative of the patient
• B. Preparing a nursing care plan in collaboration with the patient
• C. Consulting with the physician
• D. Coordinating with other members of the team

Correct answer: B

Rationale: Preparing a nursing care plan in collaboration with the patient is the best guarantee that the patient's priority needs are met because it involves actively involving the patient in their own care. This approach ensures that the patient's preferences, concerns, and priorities are taken into account when planning their care. Checking with the relative of the patient, consulting with the physician, and coordinating with other team members are important aspects of patient care, but collaborating with the patient directly ensures a patient-centered approach that addresses their individual needs and preferences.

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

• A. Actin
• B. Myosin
• C. Tropomyosin
• D. Troponin

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.

4. Which term refers to the measure of the mass of a substance per unit volume and is commonly expressed in kilograms per cubic meter?

• A. Mass
• B. Weight
• C. Density
• D. Volume

Correct answer: c

Rationale: Density is the measure of the mass of a substance per unit volume and is commonly expressed in kilograms per cubic meter (kg/m³).

5. Which sentence uses parallel structure correctly?

• A. I enjoy reading, watching movies, and to spend time with friends.
• B. Reading, watching movies, and spending time with friends are all activities I enjoy.
• C. like to read, watch movies, and spend time with friends.
• D. Reading, movies, and friends are all things I enjoy.

Correct answer: B

Rationale: Parallel structure means using the same grammatical form for elements in a list. Option (b) uses parallel gerunds ("reading," "watching," "spending"), making it the correct choice.

6. Which hormone, produced by the pituitary gland, stimulates the growth and development of bones, muscles, and organs?

• A. Growth hormone (GH)
• B. Thyroid-stimulating hormone (TSH)
• C. Prolactin
• D. Follicle-stimulating hormone (FSH)

Correct answer: A

Rationale: The correct answer is A: Growth hormone (GH). Growth hormone is produced by the pituitary gland and plays a crucial role in stimulating the growth and development of bones, muscles, and organs in the body. It promotes cell division, protein synthesis, and overall growth. Thyroid-stimulating hormone (TSH) stimulates the thyroid gland to produce thyroid hormones, prolactin is involved in milk production after childbirth, and follicle-stimulating hormone (FSH) is responsible for the growth and maturation of ovarian follicles in females and sperm production in males, but they do not directly impact the growth and development of bones, muscles, and organs. Therefore, growth hormone is the hormone specifically known for its role in promoting growth and development in these areas.
