1. What is the name of the condition characterized by swelling caused by a buildup of lymph fluid?

• A. Anemia
• B. Edema
• C. Hypertension
• D. Diabetes

Correct answer: B

Rationale: The correct answer is B: Edema. Edema is the condition characterized by swelling caused by a buildup of lymph fluid in the body's tissues. Anemia (A) is a condition characterized by a lack of healthy red blood cells, not swelling. Hypertension (C) is high blood pressure, which does not directly cause swelling. Diabetes (D) is a metabolic disorder affecting blood sugar levels and does not directly lead to lymph fluid buildup and swelling.

2. Choose the correct pronoun to complete the sentence: "Neither Michael nor Sarah ____ their homework finished yet."

• A. has
• B. have
• C. are having
• D. does have

Correct answer: B

Rationale: When referring to "neither" followed by two subjects, the verb agrees with the plural subject ("Sarah"). So, "have" is the correct answer.

3. During embryonic development, most vertebrates exhibit structures called pharyngeal pouches. These pouches eventually develop into different structures in various vertebrate groups, such as the human jaw and inner ear. Pharyngeal pouches are an example of:

• A. Analogous structures with different evolutionary origins but similar functions
• B. Homologous structures with a common evolutionary origin but diverse functions
• C. Vestigial structures that no longer serve a vital function in some organisms
• D. Atavisms, the reappearance of a trait absent in recent generations

Correct answer: B

Rationale: Rationale: Pharyngeal pouches in vertebrates are an example of homologous structures because they share a common evolutionary origin. Despite developing into different structures in various vertebrate groups, such as the jaw and inner ear in humans, these structures originated from the same ancestral feature. This concept of homology highlights the evolutionary relationship between different species and how structures can be modified over time to serve different functions while retaining a common origin.

4. How is the density of a substance calculated?

• A. Mass / Volume
• B. Volume / Mass
• C. Mass x Volume
• D. None of the above

Correct answer: A

Rationale: Density is the mass per unit volume of a substance.

5. The WBC (white blood cell) type responsible for the initial attack on pathogens is:

• A. Red blood cells
• B. Platelets
• C. Phagocytes
• D. Lymphocytes

Correct answer: C

Rationale: The correct answer is C: Phagocytes. Phagocytes are a type of white blood cell that plays a crucial role in the immune response by engulfing and destroying pathogens. They are the first line of defense against invading microorganisms, initiating the initial attack on pathogens. Red blood cells (option A) are responsible for carrying oxygen, not for immune responses. Platelets (option B) are involved in blood clotting. Lymphocytes (option D) are another type of white blood cell but are mainly responsible for specific immune responses rather than the initial attack on pathogens.

6. Ms. Valencia develops the standards to be followed. Among the following standards, which is

• A. The patients verbalized satisfaction of the nursing care received
• B. Rotation of duty will be done every four weeks for all patient care personnel.
• C. All patients shall have their weights taken recorded
• D. Patients shall answer the evaluation form before discharge

Correct answer: C

Rationale: The correct answer is C because it is a clear and specific standard that can be easily measured and monitored. Weight recording is a fundamental aspect of patient care and is essential for tracking changes in health status. Verbalized satisfaction (option A) is subjective and may not be consistently measurable. Rotation of duty (option B) is important but may not be a standard developed by a nurse manager. Answering an evaluation form before discharge (option D) is important but may not be a standard created by Ms. Valencia for all patients.
