1. As a nursing student triaging a patient, which of the following is an example of quantitative data you can gather?

• A. The patient says he feels pain.
• B. The patient says he has stabbing pain.
• C. The patient's temperature is 101.7°F.
• D. The patient reports that he had a fever yesterday.

Correct answer: C

Rationale: The corrected choice C, 'The patient's temperature is 101.7°F,' is an example of quantitative data because it provides a specific numerical value that can be measured. Quantitative data involves measurable and numerical information, making it crucial for assessing a patient's condition objectively. Choices A and B are subjective statements based on the patient's perception of pain and its description, which are qualitative data and may vary between individuals. Choice D provides historical information about a fever, which is not a current measurable value and does not constitute quantitative data for immediate assessment.

2. What is kwashiorkor, a protein deficiency disease, characterized by?

• A. Muscle wasting
• B. Night blindness
• C. Scurvy
• D. Rickets

Correct answer: A

Rationale: Kwashiorkor is a severe acute malnutrition condition resulting from insufficient dietary protein intake. It is characterized by symptoms such as edema, skin lesions, an enlarged liver with fatty infiltrates, and notably, muscle wasting. Muscle wasting occurs as the body breaks down muscle tissue to obtain essential amino acids for vital functions. Night blindness (option B) is associated with vitamin A deficiency, scurvy (option C) results from a lack of vitamin C, and rickets (option D) is caused by a deficiency in vitamin D, calcium, or phosphate.

3. Which type of waves exhibit both longitudinal and transverse motion?

• A. Electromagnetic waves
• B. Surface waves
• C. Mechanical waves
• D. Sound waves

Correct answer: B

Rationale: Surface waves exhibit both longitudinal and transverse motion. These waves travel along the boundary between two different mediums, such as water and air, causing particles to move both parallel (longitudinal) and perpendicular (transverse) to the wave's direction of travel. This unique characteristic distinguishes surface waves from other types of waves, making them the correct answer in this context. Electromagnetic waves, like light and radio waves, are purely transverse in nature, propagating through vacuum or different media through oscillating electric and magnetic fields perpendicular to the direction of wave travel. Mechanical waves, including both transverse (e.g., water waves) and longitudinal (e.g., sound waves in air) waves, do not typically exhibit both types of motion simultaneously, unlike surface waves.

4. Which of the following organs does not belong with the others?

• A. Thyroid gland
• B. Stomach
• C. Intestines
• D. Pancreas

Correct answer: B

Rationale: The correct answer is B - Stomach. The stomach is primarily involved in the digestive system, breaking down food through digestion. In contrast, the thyroid gland, intestines, and pancreas are part of the endocrine system or digestive system, involved in hormone production, nutrient absorption, and digestion. Therefore, the stomach stands out as the odd one in this group as it is the only organ specifically dedicated to digestion, while the others have dual roles or different primary functions.

5. What structure in plant cells provides rigidity and support?

• A. Cell membrane
• B. Golgi apparatus
• C. Plastid
• D. Cell wall

Correct answer: D

Rationale: The correct answer is D, the cell wall. The cell wall is the structure in plant cells that provides rigidity and support. It is a tough, rigid structure located outside the cell membrane. Composed primarily of cellulose, the cell wall offers structural support to the cell, helping it maintain its shape and protect it from damage. The other choices, such as the cell membrane (choice A), Golgi apparatus (choice B), and plastid (choice C) do not provide rigidity and support to plant cells. The cell membrane is a selectively permeable barrier, the Golgi apparatus is involved in processing and packaging proteins, and plastids are organelles responsible for functions like photosynthesis and storage, but they do not provide the structural support that the cell wall does.
