1. When checking for proper blood pressure cuff size, which guideline is correct?

• A. The standard cuff size is appropriate for all sizes.
• B. The length of the rubber bladder should equal 80% of the arm circumference.
• C. The width of the rubber bladder should equal 80% of the arm circumference.
• D. The width of the rubber bladder should equal 40% of the arm circumference.

Correct answer: D

Rationale: When selecting the correct blood pressure cuff size, it is essential to ensure that the width of the rubber bladder equals 40% of the circumference of the person's arm. This ensures proper fitting and accurate readings. The length of the bladder should actually equal 80% of the arm circumference, not 80% of the width, making choices B and C incorrect. Choice A stating that the standard cuff size is appropriate for all sizes is inaccurate, as using an incorrectly sized cuff can lead to inaccurate blood pressure readings.

2. What does an individual who believes in the magicoreligious theory of illness and disease think is the cause of illness?

• A. Germs and viruses
• B. Supernatural forces
• C. Eating imbalanced (hot/cold) foods
• D. Imbalance within his or her spiritual nature

Correct answer: B

Rationale: Individuals who adhere to the magicoreligious theory of illness and disease attribute the cause of illness to supernatural forces. In this perspective, the world is perceived as governed by supernatural forces that influence the well-being of individuals. The belief is that these forces can bring about both good and evil outcomes. Choices A, C, and D are incorrect. Germs and viruses are associated with the biomedical theory of illness. Eating imbalanced hot or cold foods is linked to the yin/yang naturalist theory. Imbalance within one's spiritual nature is not a recognized cause of illness in any of the established theories of illness.

3. Each small square on the EKG paper is:

• A. 0.04 seconds long and 5mm tall
• B. 0.2 seconds long and 5mm tall
• C. 0.04 seconds long and 20mm tall
• D. 0.04 seconds long and 1mm tall

Correct answer: D

Rationale: Each small square on an EKG paper represents 0.04 seconds long and 1mm tall. This standardization is essential for accurate measurements. One large square on EKG paper consists of 5 small squares in length and 5 small squares in height, which equals 0.2 seconds long and 5mm tall (0.5 mV). Choice A is incorrect because while the duration is correct, the height mentioned is not accurate. Choice B is incorrect as it provides the correct height but the duration is inaccurate. Choice C is incorrect as the height mentioned is exaggerated, and the duration is correct but the height is not. Therefore, the correct answer is 0.04 seconds long and 1mm tall.

4. When performing an EKG, the patient starts to laugh out of feelings of anxiety. What would you expect the EKG to show? (Choose the BEST answer.)

• A. Increased pulse rate, normal EKG
• B. Decreased pulse rate, abnormal EKG
• C. Tachycardia, poor EKG graph
• D. Bradycardia, poor EKG graph

Correct answer: C

Rationale: When a patient laughs due to anxiety during an EKG, it is likely to cause tachycardia, which is a rapid heart rate. This increased heart rate can lead to poor EKG graph quality as the electrical signals from large moving muscles can interfere with data collection from the chest leads. Therefore, in this scenario, the EKG is expected to show tachycardia with poor graph quality. Choices A, B, and D are incorrect because a patient laughing out of anxiety is more likely to result in an increased pulse rate (tachycardia) rather than a decreased pulse rate (bradycardia) or a normal EKG.

5. The healthcare provider is preparing to use an otoscope for an examination. Which statement is true regarding the otoscope?

• A. Often used to direct light into the sinuses
• B. Used to examine the structures of the internal ear
• C. Uses a short, broad speculum to help visualize the ear
• D. Directs light into the ear canal and onto the tympanic membrane

Correct answer: D

Rationale: The otoscope is a tool used to examine the ear canal and tympanic membrane, which separates the external and middle ear. It is not intended to direct light into the sinuses or examine the internal structures of the ear. The otoscope typically uses a short, narrow speculum to aid in visualizing the ear canal and tympanic membrane, not a short, broad speculum as mentioned in choice C.
