1. Scientific notation is a way to represent very large or small numbers in a compact form. If a number is written as 4.82 x 10^3, what is the value of the number in standard form?

• A. 0.004 82
• B. 0.482
• C. 4820
• D. 4820000

Correct answer: C

Rationale: Rationale: When a number is written in scientific notation as \(a \times 10^n\), the value of the number in standard form is obtained by multiplying \(a\) by \(10^n\). In this case, the number is \(4.82 \times 10^3\). To convert this to standard form, we multiply 4.82 by \(10^3\), which means moving the decimal point 3 places to the right. \(4.82 \times 10^3 = 4820\) Therefore, the value of the number in standard form is 4820, which corresponds to option C.

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. What is the term for the shedding of the outermost layer of the epidermis?

• A. Desquamation
• B. Exfoliation
• C. Keratinization
• D. Epidermolysis

Correct answer: A

Rationale: The correct term for the shedding of the outermost layer of the epidermis is desquamation. Desquamation is a natural process where old skin cells are shed off to make way for new cells. Exfoliation refers to the removal of dead skin cells through external means like scrubs. Keratinization is the process by which skin cells produce the protein keratin, while epidermolysis is a condition where the epidermis separates from the dermis. Therefore, in this context, desquamation is the most appropriate term for the shedding of the outermost layer of the epidermis.

4. When proofreading your writing, focus on:

• A. Changing the wording to sound more original.
• B. Ignoring minor grammatical errors like typos.
• C. Checking for clarity, consistency, and overall flow.
• D. Replacing common words with thesaurus alternatives.

Correct answer: C

Rationale: Proofreading involves correcting errors, refining sentence structure, and ensuring the writing achieves its purpose, clarity, and consistency.

5. Which of the following is NOT a part of the body's innate immune response?

• A. Physical barriers like skin and mucous membranes
• B. Phagocytes that engulf and destroy pathogens
• C. Inflammatory response to isolate and contain infection
• D. Production of antibodies specific to a particular pathogen

Correct answer: D

Rationale: The correct answer is D. The body's innate immune response is the first line of defense against pathogens, and it includes physical barriers like skin and mucous membranes (option A), phagocytes that engulf and destroy pathogens (option B), and the inflammatory response to isolate and contain infections (option C). The production of antibodies specific to a particular pathogen (option D) is part of the adaptive immune response, which develops over time and is not considered part of the innate immune system. Therefore, option D is not a component of the body's innate immune response.

6. Which word is misspelled?

• A. accommodate
• B. acquiesce
• C. circumstance
• D. indelible

Correct answer: D

Rationale: "Indelible" is spelled correctly, while "circumstance" should be "circumstance."
