1. 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.

2. A patient's height is 1.65 meters and their weight is 75kg. Calculate their BMI and interpret the result.

A. 23.1 (Overweight)
B. 25.3 (Overweight)
C. 27.7 (Overweight)
D. 32.8 (Obese)

Correct answer: C

Rationale: Divide weight (75kg) by height squared (1.65m^2) to get BMI (27.7). This falls within the "overweight" category (25-29.9 BMI).

3. What is the final stage of both mitosis and meiosis?

A. Interphase
B. Telophase
C. Cytokinesis
D. G1 phase

Correct answer: B

Rationale: Rationale: - Interphase (option A) is not the final stage of mitosis or meiosis; it is the phase before cell division where the cell prepares for division by growing and replicating its DNA. - Telophase (option B) is the final stage of both mitosis and meiosis. During telophase, the separated chromosomes reach opposite poles of the cell, the nuclear membrane reforms around each set of chromosomes, and the chromosomes begin to decondense. - Cytokinesis (option C) is the process of dividing the cytoplasm to form two separate daughter cells. While it occurs after telophase, it is not considered the final stage of mitosis or meiosis. - G1 phase (option D) is the first gap phase in the cell cycle, occurring before DNA replication. It is not the final stage of mitosis or meiosis.

4. Which hormone is responsible for regulating blood sugar levels and is produced by the pancreas?

A. Insulin
B. Glucagon
C. Testosterone
D. Estrogen

Correct answer: A

Rationale: The correct answer is A: Insulin. Insulin is a hormone produced by the pancreas that plays a crucial role in regulating blood sugar levels. When blood sugar levels rise after a meal, insulin is released to help cells absorb glucose for energy or storage. This process helps to lower blood sugar levels. Glucagon, the hormone mentioned in option B, is also produced by the pancreas but has the opposite effect of raising blood sugar levels when they are too low. Testosterone and estrogen, options C and D, are sex hormones and are not directly involved in regulating blood sugar levels.

5. The term "barn" is a unit commonly used in nuclear physics to quantify:

A. Energy (Electron volts are the standard unit for energy in nuclear physics)
B. Radioactivity
C. Nuclear cross-section
D. Half-life

Correct answer: C

Rationale: The term 'barn' is a unit of measurement used in nuclear physics to quantify nuclear cross-section. Nuclear cross-section refers to the measure of the probability of a specific interaction occurring between particles during a nuclear reaction. The term 'barn' was coined based on its relation to the physical size of a nucleus, as it is a small unit of area used to describe the likelihood of a particle interacting with a nucleus. It is not used to quantify energy, radioactivity, or half-life, making options A, B, and D incorrect in this context.

6. What is the scientific name for the tear gland?

A. Lachrymal gland
B. Lacrimal sac
C. Lacrimal duct
D. Lacrimal papilla

Correct answer: A

Rationale: The lachrymal gland is the almond-shaped gland located above each eye, responsible for producing tears. Tears are a complex mixture of water, electrolytes, proteins, and other substances that help lubricate and protect the eyes from dryness and irritation.
