1. The healthcare provider is examining a patient who is reporting "feeling cold."? Which is a mechanism of heat loss in the body?

• A. Exercise
• B. Radiation
• C. Metabolism
• D. Food digestion

Correct answer: B

Rationale: When the body needs to lose heat, one of the mechanisms it employs is radiation. Radiation involves the transfer of heat from the body to the environment in the form of infrared waves. While metabolism, exercise, and food digestion contribute to heat production, they are not mechanisms for heat loss. Metabolism generates heat as a byproduct, exercise increases metabolic rate leading to heat production, and food digestion involves some heat generation, but these processes do not directly facilitate heat loss. Therefore, in the scenario where the patient is feeling cold, radiation is the primary mechanism for the body to lose excess heat and maintain a stable internal temperature.

2. Patients exhibiting signs of cyanosis will:

• A. show signs of hyperoxia.
• B. have increased O2 saturation.
• C. have blood levels of CO2 higher than O2 levels.
• D. None of the above.

Correct answer: C

Rationale: Cyanosis is a bluish discoloration of the skin and mucous membranes resulting from low blood oxygen levels. When a patient exhibits cyanosis, it indicates that their blood is poorly oxygenated, leading to a higher concentration of CO2 compared to oxygen. Options A and B are incorrect as cyanosis is associated with low oxygen levels, not hyperoxia or increased O2 saturation. Therefore, the correct answer is that patients exhibiting cyanosis will have blood levels of CO2 higher than O2 levels.

3. 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.

4. A client is having difficulties reading an educational pamphlet. He cannot find his glasses. In order to read the words, he must hold the pamphlet at arm's length, which allows him to read the information. Which vision deficit does this client most likely suffer from?

• A. Cataracts
• B. Glaucoma
• C. Astigmatism
• D. Presbyopia

Correct answer: D

Rationale: Presbyopia is a condition that occurs when the lens of the eye loses accommodation and is unable to focus light on objects nearby. As a result, clients are unable to see or read items up close but may have success when holding the same item at arm's length. Many clients with presbyopia must wear bifocals, but long-distance vision remains unaffected. Cataracts involve clouding of the eye's lens, leading to blurry vision. Glaucoma is associated with increased intraocular pressure that damages the optic nerve, causing vision loss. Astigmatism is a refractive error where the cornea or lens has an irregular shape, leading to distorted or blurred vision.

5. What is the first aid for frostbite?

• A. Running cold water over the affected area. Warm or hot water will shock the area and cause more tissue damage.
• B. Run warm water over the area to rapidly rewarm the affected area.
• C. Run hot water over the area to warm the area as quickly as possible.
• D. Cover the area with a blanket, using a heating pad if the blanket isn't warm enough.

Correct answer: A

Rationale: First aid for frostbite involves running cold water over the affected area. It is important to avoid warm or hot water as it can shock the area and cause further tissue damage. Warm water should not be used to rapidly rewarm the affected area. Similarly, hot water should also be avoided as it can warm the area too quickly and potentially cause harm. Covering the area with a blanket and using a heating pad may not be effective and can even lead to more damage. Seeking medical assistance is crucial if the tissue appears necrotic to prevent further complications.
