1. She checks the documentary requirements for the applicants for staff nurse position. Which

A. Certificate of previous employment
B. Record of related learning experience (RLE)
C. Membership to accredited professional organization
D. Professional identification card

Correct answer: C

Rationale: The correct answer is C: 'Membership to accredited professional organization.' When hiring staff nurses, verifying their membership to an accredited professional organization is crucial as it ensures that the applicant is recognized and affiliated with a reputable body in the nursing field. This membership signifies adherence to professional standards and ongoing education and development. While the other options are important in assessing a candidate's qualifications, membership to an accredited professional organization directly relates to the professional standing and commitment to the nursing profession, making it a key documentary requirement for the staff nurse position.

2. What type of sentence is the following: "Wow, what a beautiful sunset!"

A. Interrogative sentence
B. Declarative sentence
C. Exclamatory sentence
D. Imperative sentence

Correct answer: C

Rationale: The sentence expresses an emotion ("Wow") and makes an exclamation, making it an exclamatory sentence.

3. What is the primary function of hair on the human body?

A. Insulation
B. Sensory perception
C. Protection
D. Vitamin D synthesis

Correct answer: A

Rationale: The primary function of hair on the human body is insulation. Hair acts as a protective layer to help regulate body temperature by trapping heat close to the skin. This insulation property is especially important in colder climates to prevent excessive heat loss from the body. While hair can also provide some level of protection from external elements and minor injuries, its main role is to insulate the body. Sensory perception is mainly attributed to nerve endings in the skin rather than hair. Vitamin D synthesis is primarily dependent on exposure to sunlight rather than hair. Therefore, option A, insulation, is the correct answer.

4. A major factor influencing the distribution of organisms geographically is:

A. The availability of specific types of food sources
B. olerance of organisms to different temperature ranges
C. Competition for mates within the same species
D. All of the above

Correct answer: D

Rationale: Rationale: The distribution of organisms geographically is influenced by a variety of factors, including the availability of specific types of food sources (option A). Organisms need to have access to suitable food sources in order to survive and thrive in a particular area. Additionally, the tolerance of organisms to different temperature ranges (option B) is crucial as temperature can greatly impact where certain species can live. Organisms must be able to withstand the temperature conditions of a given environment to survive there. Competition for mates within the same species (option C) can also play a role in the distribution of organisms, as it can affect population sizes and dynamics in different areas. Therefore, all of these factors - food availability, temperature tolerance, and competition for mates - collectively influence the distribution of organisms geographically.

5. The Merkel cells, located in the epidermis, are specialized for:

A. Melanin production
B. Temperature sensation
C. Touch perception
D. Immune defense

Correct answer: C

Rationale: The correct answer is C: 'Touch perception.' Merkel cells, also known as Merkel discs, are found in the skin's epidermal layer and are responsible for sensing touch. These cells are located near nerve endings and help detect light touch and pressure on the skin. They play a crucial role in the perception of tactile sensations and are not involved in melanin production, temperature sensation, or immune defense. Therefore, the specialized function of Merkel cells is primarily related to touch perception, making option C the correct choice.

6. Which hormone is responsible for regulating sleep-wake cycles and is influenced by light exposure?

A. Melatonin
B. Cortisol
C. Estrogen
D. Glucagon

Correct answer: A

Rationale: The correct answer is A: Melatonin. Melatonin is a hormone produced by the pineal gland in the brain and plays a crucial role in regulating the sleep-wake cycle, also known as the circadian rhythm. Melatonin levels typically rise in the evening in response to darkness and help signal to the body that it's time to sleep. Exposure to light, especially blue light, can inhibit the production of melatonin, making us more alert and awake. Cortisol (option B) is a stress hormone that helps regulate metabolism and immune response. Estrogen (option C) is a female sex hormone, and glucagon (option D) is a hormone that increases blood sugar levels. Therefore, the hormone responsible for regulating sleep-wake cycles and influenced by light exposure is melatonin.
