1. What information can be obtained directly from the element's atomic number?

• A. Its atomic mass
• B. Its position on the periodic table
• C. Its position on the periodic table
• D. Its chemical properties

Correct answer: B

Rationale: The atomic number of an element represents the number of protons in the nucleus of an atom. This number determines the element's unique identity and its position on the periodic table. The atomic mass (option A) is not directly determined by the atomic number but is a weighted average of the isotopes of an element. The position on the periodic table (option C) is directly related to the atomic number, as elements are arranged in order of increasing atomic number. The chemical properties of an element (option D) are influenced by the number of protons in the nucleus, which is determined by the atomic number.

2. The lymphatic system is a network of vessels and organs that plays a vital role in:

• A. Transporting oxygen and nutrients to cells
• B. Carrying waste products away from tissues
• C. Regulating body temperature
• D. Producing red blood cells

Correct answer: B

Rationale: The correct answer is B: Carrying waste products away from tissues. The lymphatic system is responsible for collecting excess fluid and waste products from tissues and returning them to the bloodstream for removal. This helps maintain fluid balance in the body and supports immune function by transporting white blood cells to fight infections. Options A, C, and D do not accurately describe the function of the lymphatic system. Transporting oxygen and nutrients to cells is primarily the role of the circulatory system, while regulating body temperature is controlled by the nervous system and producing red blood cells occurs in the bone marrow.

3. Which sentence uses the semicolon correctly?

• A. The play was long; however, it was very entertaining.
• B. The guests arrived; Sarah greeted them at the door.
• C. John likes apples; Mary prefers oranges.
• D. He was tired; he went to bed early.

Correct answer: B

Rationale: Option B joins two independent clauses related to the same event.

4. A patient's temperature is 98.6 degrees Fahrenheit. What is their temperature in degrees Celsius (1°F = 5/9°C)?

• A. 32°C
• B. 37°C
• C. 41°C
• D. 45°C

Correct answer: A

Rationale: Subtract 32 from the Fahrenheit temperature (98.6°F) and then multiply by 5/9 to get 37°C.

5. Which of the following is NOT a function of the endocrine system?

• A. Regulating growth and development
• B. Maintaining blood sugar levels
• C. Controlling mood and emotions
• D. Facilitating digestion through muscle contractions

Correct answer: D

Rationale: The endocrine system is responsible for producing hormones that regulate various bodily functions. Option D, facilitating digestion through muscle contractions, is actually a function of the muscular and digestive systems, not the endocrine system. The endocrine system primarily regulates growth and development, maintains blood sugar levels through hormones like insulin and glucagon, and also plays a role in controlling mood and emotions through hormones such as serotonin and cortisol. Therefore, option D is correct as it is not a function directly associated with the endocrine system.

6. 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.
