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 performing a physical examination, safety must be considered to protect the examiner and the patient against the spread of infection. Which of these statements describes the most appropriate action the nurse would take when performing a physical examination?

• A. Washing one's hands after removing gloves is necessary, even if the gloves are still intact
• B. Hands are washed before and after every physical patient encounter
• C. Hands are washed before the examination of each body system to prevent the spread of bacteria from one part of the body to another
• D. Gloves are worn throughout the entire examination to demonstrate concern regarding the spread of infectious diseases

Correct answer: B

Rationale: The most appropriate action for the nurse to take when performing a physical examination is to wash their hands before and after every physical patient encounter. This practice helps prevent the spread of infection. Hands should also be washed after contact with blood, body fluids, secretions, and excretions, and after contact with any equipment contaminated with body fluids. It is crucial to wash hands after removing gloves, even if the gloves appear intact. Choice A is incorrect because washing hands after removing gloves is necessary to ensure thorough hygiene. Choice C is incorrect because hands should be washed before and after every patient encounter, not just before examining each body system. Choice D is incorrect because gloves should be worn when there is potential contact with body fluids, but they do not need to be worn throughout the entire examination.

3. When percussing over the lungs of a 4-year-old child, the nurse hears bilateral loud, long, and low tones. How should the nurse proceed?

• A. Palpate over the area for increased pain and tenderness.
• B. Ask the child to take shallow breaths and percuss over the area again.
• C. Refer the child to a specialist because of an increased amount of air in the lungs.
• D. Consider this finding as normal for a child this age and proceed with the examination.

Correct answer: D

Rationale: In pediatric patients, loud, long, and low tones heard when percussing over the lungs are normal findings. These percussion notes are characteristic of a child's lung due to its thin chest wall and increased air content. It is unnecessary to palpate for pain and tenderness, ask the child to take shallow breaths and repeat the percussion, or refer the child to a specialist. Therefore, the correct action is to consider these findings as normal for the child's age and continue with the examination.

4. 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.

5. In a 68-year-old man, a gradual loss of hearing is known as _____________.

• A. presbycusis
• B. xerostomia
• C. myopia
• D. presbyopia

Correct answer: A

Rationale: The correct answer is 'presbycusis.' Presbycusis is the age-related gradual loss of hearing ability, commonly seen in the elderly population. Xerostomia refers to dry mouth, myopia is nearsightedness, and presbyopia is the age-related loss of the eye's ability to focus on close objects. Given Mr. Roberts' age and symptom of gradual hearing loss, presbycusis is the most likely diagnosis. Xerostomia, myopia, and presbyopia do not match the sensory change described in the question, making them incorrect choices.
