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. A urine pregnancy test:

• A. May be negative even if a blood pregnancy test is positive.
• B. Is positive only during the first trimester of pregnancy.
• C. Will be negative if the amount of LH isn't enough to meet or exceed the sensitivity of the testing device.
• D. All of the above.

Correct answer: A

Rationale: A urine pregnancy test detects HCG in a pregnant woman's urine. Blood levels of HCG are usually higher and register earlier than HCG levels in the urine. Choice A is correct because urine pregnancy tests may be negative even if a blood pregnancy test is positive due to the differences in HCG levels in blood and urine. Choice B is incorrect because a urine pregnancy test can be positive throughout pregnancy, not just in the first trimester. Choice C is incorrect because LH (luteinizing hormone) is not the hormone detected in a pregnancy test; it is HCG (human chorionic gonadotropin). Choice D is incorrect because not all the statements provided are true.

3. Which of the following is a disadvantage of using a dry heat application?

• A. Dry heat is more likely to cause burns than moist heat
• B. Dry heat does not penetrate deeply into the tissues
• C. Dry heat causes the skin to dry out more quickly
• D. Dry heat can quickly cause skin breakdown

Correct answer: C

Rationale: The correct answer is that dry heat causes the skin to dry out more quickly. When comparing dry and moist heat applications, dry heat is less likely to cause burns and skin breakdown. However, one of the disadvantages of dry heat is that it does not penetrate deeply into the tissues and may lead to faster drying out of the skin. This can have negative effects on skin integrity and overall comfort during therapy. Choice A is incorrect because dry heat is less likely to cause burns than moist heat. Choice B is incorrect as dry heat may not penetrate deeply into tissues. Choice D is incorrect as dry heat is less likely to cause skin breakdown compared to moist heat.

4. Which of the following interventions is most appropriate for a client with a diagnosis of Risk for Activity Intolerance?

• A. Perform nursing activities throughout the entire shift
• B. Assess for signs of increased muscle tone
• C. Minimize environmental noise
• D. Teach clients to perform the Valsalva maneuver

Correct answer: C

Rationale: The most appropriate intervention for a client diagnosed with Risk for Activity Intolerance is to minimize environmental noise. Environmental noise can increase the energy demand on the client as they try to manage their responses to stimuli. By reducing excess noise, the nurse helps promote rest and conserves the client's energy, which is crucial in managing activity intolerance. Choice A is incorrect because increasing nursing activities may exacerbate the client's intolerance to activity. Choice B is incorrect as assessing for signs of increased muscle tone does not directly address the issue of activity intolerance. Choice D is incorrect as teaching the Valsalva maneuver is not relevant to managing activity intolerance in this scenario.

5. What does preload refer to?

• A. The volume of blood entering the left side of the heart
• B. The volume of blood entering the right side of the heart
• C. The pressure in the venous system that the heart must overcome to pump the blood
• D. The pressure in the arterial system that the heart must overcome to pump the blood

Correct answer: B

Rationale: Preload refers to the volume of blood that enters the right side of the heart. This volume stretches the fibers in the heart before contraction. Preload is an essential factor in determining the force of ventricular contraction. Choices A, C, and D are incorrect. Choice A is incorrect because preload is specifically related to the volume of blood entering the right side of the heart. Choices C and D are incorrect as they refer to afterload, which is the pressure that the heart must overcome to pump blood out of the ventricles into the systemic or pulmonary circulation.
