1. The most accurate reading for a temperature is done:

A. Orally
B. Aurally through a clean canal
C. Rectally
D. Axially

Correct answer: B

Rationale: Aural readings are done through the ear canal. The tympanic membrane shares a blood supply with the hypothalamus, the brain area that regulates body temperature. Taking the temperature aurally through a clean canal ensures an accurate reading. Choice A (Orally) is not the most accurate method for temperature measurement as it can be affected by external factors like drinking hot or cold liquids. Choice C (Rectally) is invasive and less practical for routine temperature monitoring. Choice D (Axially) is not a standard method for temperature measurement and may not provide accurate results.

2. A student is late for an appointment and has rushed across campus to the health clinic. How should the nurse proceed?

A. Allow 5 minutes for the student to relax and rest before checking their vital signs.
B. Check the blood pressure in both arms, expecting a difference in the readings due to the recent exercise.
C. Immediately monitor the student's vital signs upon arrival at the clinic and then 5 minutes later, recording any differences.
D. Check the student's blood pressure in the supine position to provide a more accurate reading and allow the student to relax at the same time.

Correct answer: A

Rationale: To ensure an accurate blood pressure reading, it is important for the student to be in a relaxed state. Allowing at least a 5-minute rest period helps reduce anxiety and provides a valid blood pressure measurement. Checking the blood pressure in both arms is unnecessary unless there is a specific reason to suspect an issue, and recent exercise should not significantly impact the readings. Monitoring vital signs immediately upon arrival may not yield accurate results due to the rush and anxiety of the student. Checking blood pressure in the supine position is not necessary in this scenario and does not provide a more accurate reading.

3. The nurse is preparing to examine a 6-year-old child. Which action is most appropriate?

A. The child is asked to undress from the waist up.
B. The head is examined before the thorax, abdomen, and genitalia.
C. The nurse should keep in mind that a child at this age will have a sense of modesty.
D. Talking about the equipment being used is avoided to prevent increasing the child's anxiety.

Correct answer: C

Rationale: When examining a 6-year-old child, it is important to consider their sense of modesty. The child should undress themselves, leaving underpants on and using a gown or drape to maintain privacy. Additionally, a school-age child like a 6-year-old is curious about how equipment works, so it is beneficial to explain the purpose and function of the tools being used. The examination sequence should typically progress from the child's head to the toes to ensure a thorough assessment. Therefore, choices A, B, and D are incorrect as they do not align with the appropriate approach to examining a 6-year-old child.

4. During a class on the aspects of culture, the instructor shares that culture has four basic characteristics. Which statement correctly reflects one of the characteristics of culture?

A. Static and unchanging
B. Members sharing similar physical characteristics
C. Members sharing a common geographic origin and religion
D. Adapted to specific conditions related to environmental and technical factors

Correct answer: D

Rationale: Culture has four basic characteristics, one of which is that it is adapted to specific conditions related to environmental and technical factors and to the availability of natural resources. The other three characteristics are: (1) learned from birth through the processes of language acquisition and socialization; (2) shared by all members of the cultural group; and (3) dynamic and ever-changing. Culture is not static and unchanging but is dynamic and ever-changing. Members of a culture do not necessarily share similar physical characteristics; that refers to race. Similarly, members of a culture do not necessarily share a common geographic origin and religion; that refers to ethnicity.

5. How many cc are there in 25 ounces?

A. 250
B. 500
C. 750
D. 1000

Correct answer: C

Rationale: To convert ounces to cc, we know that there are 30 cc in 1 ounce. Therefore, to find out how many cc are in 25 ounces, we multiply 30 cc/ounce by 25 ounces which equals 750 cc. This makes choice C, 750, the correct answer. Choices A, B, and D are incorrect as they do not correctly convert ounces to cc.
