Nokea
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.

What is the first number in a blood pressure reading?
- A. Diastolic pressure
- B. Mean arterial pressure
- C. Pulse rate
- D. Systolic pressure
Correct Answer: D
Rationale: The correct answer is D: Systolic pressure. In a blood pressure reading, the first number represents the systolic pressure, which is the maximum pressure in the arteries during heart contraction. The second number in the reading is the diastolic pressure, which indicates the pressure in the arteries when the heart is at rest. Choices A, B, and C are incorrect because diastolic pressure, mean arterial pressure, and pulse rate are not the first numbers in a blood pressure reading.
What is the role of the spleen in the body?
- A. To produce bile
- B. To filter blood and remove old red blood cells
- C. To produce red blood cells
- D. To store fat
Correct Answer: B
Rationale: The correct answer is B. The spleen acts as a blood filter, removing old or damaged red blood cells. It also plays a role in immune responses, storing blood reserves, and helping to fight infection. The production of bile is primarily associated with the liver, not the spleen. While the bone marrow is responsible for red blood cell production, the spleen's main functions do not include this process. Storing fat is not a primary function of the spleen.
What are the components of the female external genitalia and their functions?
- A. Ovaries: internal reproductive organs
- B. Vulva: external structures of the female genitalia
- C. Uterus: internal reproductive organ for fetal development
- D. Vagina: birth canal
Correct Answer: B
Rationale: The corrected answer is B: 'Vulva: external structures of the female genitalia.' The vulva includes external structures such as the labia, clitoris, and vaginal opening. These structures play roles in sexual arousal and protection of the internal genital organs. Choices A, C, and D are incorrect because they are internal reproductive organs. The ovaries produce eggs, the uterus houses the developing fetus, and the vagina serves as the birth canal. Hence, they are not components of the female external genitalia.
What is the function of the immune system?
- A. To transport oxygen
- B. To fight infection
- C. To digest food
- D. To produce hormones
Correct Answer: B
Rationale: The correct answer is B: 'To fight infection.' The immune system's primary function is to protect the body from infections and foreign invaders by recognizing and responding to pathogens. It plays a crucial role in maintaining overall health and preventing diseases caused by harmful microorganisms. Choices A, C, and D are incorrect because the immune system is not responsible for transporting oxygen, digesting food, or producing hormones. These functions are carried out by other systems in the body, such as the respiratory system, digestive system, and endocrine system, respectively.
Where does sperm production occur?
- A. Prostate gland
- B. Seminal vesicles
- C. Scrotum
- D. Seminiferous tubules
Correct Answer: D
Rationale: Sperm production occurs in the seminiferous tubules within the testes. These tubules are responsible for spermatogenesis, the process of sperm creation. The prostate gland and seminal vesicles contribute to seminal fluid production, while the scrotum houses the testes but does not produce sperm. Therefore, choices A, B, and C are incorrect as they are not sites for sperm production.
