1. Which of the following guidelines should be least considered in formulating objectives for

A. Written nursing care plan
B. Holistic approach
C. Prescribed standards
D. Staff preferences

Correct answer: D

Rationale: When formulating objectives for a written nursing care plan, staff preferences should be least considered. Objectives should be based on patient needs, evidence-based practice, and professional standards rather than personal preferences of the staff. Prescribed standards ensure quality care and adherence to best practices. A holistic approach considers the whole patient, including physical, emotional, and spiritual aspects. Staff preferences may introduce bias and should not dictate patient care objectives.

2. What is the principle behind the phenomenon of refraction, where waves bend when entering a new medium?

A. Change in wavelength
B. Change in frequency
C. Change in wave speed
D. None of the above

Correct answer: C

Rationale: Refraction occurs because of the change in wave speed as it enters a new medium, causing the wavefront to bend and change direction.

3. Which property of a wave determines its loudness in sound waves?

A. Amplitude
B. Wavelength
C. Frequency
D. Speed

Correct answer: a

Rationale: Amplitude in sound waves relates to the loudness or intensity of the sound.

4. After discussing the possible effects of the low patient satisfaction rate, the staff started to list

A. Collaboration
B. Majority rule
C. Dominance
D. Compromise

Correct answer: B

Rationale: The correct answer is B: 'Majority rule.' In this scenario, the staff is likely listing potential solutions or actions based on the opinion or agreement of the majority. Collaboration (A) involves working together towards a common goal, while Dominance (C) implies one person or group having control. Compromise (D) suggests finding a middle ground between different viewpoints. Majority rule best fits the situation where a decision or list of actions is being determined by what most people agree on, which is a common approach in group decision-making processes.

5. Which statement accurately describes cytokinesis in animal cells?

A. Which statement accurately describes cytokinesis in animal cells?
B. A cell plate forms in the center of the dividing cell, eventually separating the cytoplasm into two daughter cells.
C. A cell plate forms in the center of the dividing cell, eventually separating the cytoplasm into two daughter cells.
D. The nucleus elongates and pulls apart, physically dividing the cytoplasm into two.

Correct answer: B

Rationale: Rationale: A) This statement is a duplicate of option C and does not accurately describe cytokinesis in animal cells. B) In animal cells, during cytokinesis, a cleavage furrow forms in the center of the dividing cell. This furrow deepens and eventually pinches the cytoplasm into two daughter cells. This process is distinct from plant cells, where a cell plate forms. C) This statement is a duplicate of option A and does not accurately describe cytokinesis in animal cells. D) This statement describes the process of nuclear division (mitosis) rather than cytokinesis, which is the division of the cytoplasm.

6. Hair follicles are openings in the skin that house

A. Blood vessels (Blood vessels are not housed in hair follicles)
B. Nerve endings (Nerve endings are present but not housed within)
C. Hair shafts and hair roots
D. Sebaceous glands (These glands are often attached to hair follicles)

Correct answer: C

Rationale: Hair follicles are structures in the skin that house both the hair shaft and the hair root. The hair shaft is the visible part of the hair that extends from the skin's surface, while the hair root is the part embedded within the hair follicle and extends into the deeper layers of the skin. The sebaceous glands, which produce sebum (an oily substance), are typically attached to hair follicles and help lubricate and protect the hair and skin. Blood vessels and nerve endings are present in the skin but are not housed within the hair follicles themselves. Therefore, the correct answer is C, as hair follicles contain both the hair shaft and hair root.
