Nursing Elites

1. The nurse is reviewing the hot/cold theory of health and illness. Which statement best describes the basic tenets of this theory?

• A. The causation of illness is based on supernatural forces that influence the humors of the body.
• B. Herbs and medicines are classified based on their physical characteristics of hot and cold and the humors of the body.
• C. The four humors of the body consist of blood, yellow bile, black bile, and phlegm.
• D. The treatment of disease consists of adding or subtracting cold, heat, dryness, or wetness to restore the balance of the humors of the body.

Correct answer: D

Rationale: The hot/cold theory of health and illness is based on the four humors of the body: blood, phlegm, black bile, and yellow bile. These humors regulate the basic bodily functions, described in terms of temperature, dryness, and moisture. The treatment of disease in this theory involves adding or subtracting cold, heat, dryness, or wetness to restore the balance of the humors. Choice A is incorrect as the theory is not based on supernatural forces but on the balance of bodily humors. Choice B is incorrect as herbs and medicines are not classified solely based on their physical characteristics of hot and cold in this theory. Choice C is incorrect as the four humors are blood, phlegm, black bile, and yellow bile, not spiritual connectedness or social aspects. Therefore, the correct choice is D, as it accurately reflects a foundational tenet of the hot/cold theory of health and illness.

2. 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.

3. A healthcare provider attempts to plug in a sequential compression device when they notice a tingling sensation in their hands while touching the cord. What is the next action of the healthcare provider?

• A. Attempt to plug the device into a different outlet
• B. Inspect the cord for damage; if none is present, continue to use the device
• C. Discontinue the device and send it to the maintenance department for inspection
• D. Notify the supervisor that the unit is at risk of an electrical fire

Correct answer: C

Rationale: Feeling a tingling sensation when touching an electrical cord is a warning sign that the device may be malfunctioning. This sensation indicates a potential electrical current leak, which could pose a risk of harm. The correct action is to immediately discontinue the use of the device and send it to the maintenance department for inspection. Continuing to use the device without addressing the issue could lead to electric shock or fire hazards. Trying to plug the device into a different outlet does not address the underlying problem of potential device malfunction. Notifying the supervisor about the risk of an electrical fire is important, but the immediate action should be to stop using the device and have it inspected by maintenance professionals. Therefore, the best course of action is to discontinue the device and ensure it is checked thoroughly before further use.

4. The healthcare professional has collected the following information on a patient: palpated blood pressure"?180 mm Hg; auscultated blood pressure"?170/100 mm Hg; apical pulse"?60 beats per minute; radial pulse"?70 beats per minute. What is the patient's pulse pressure?

• A. 10
• B. 70
• C. 80
• D. 100

Correct answer: B

Rationale: Pulse pressure is the numerical difference between the systolic and diastolic blood pressure readings. In this case, the systolic blood pressure is 170 mm Hg, and the diastolic blood pressure is 100 mm Hg. Therefore, the pulse pressure is calculated as 170 - 100 = 70 mm Hg. Pulse pressure reflects the stroke volume, the amount of blood ejected from the heart with each beat. Choices A, C, and D are incorrect because they do not accurately represent the difference between the systolic and diastolic blood pressure readings provided.

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.
