1. Many Asians believe in the yin/yang theory, which is rooted in the ancient Chinese philosophy of Tao. Which statement most accurately reflects this philosophy's view of "health"??
- A. A person is able to work and produce.
- B. A person is happy, stable, and feels good.
- C. All aspects of the person are in perfect balance.
- D. A person is able to care for others and function socially.
Correct answer: C
Rationale: In the yin/yang theory rooted in ancient Chinese philosophy, health is believed to exist when all aspects of a person are in perfect balance. This includes physical, mental, emotional, and spiritual well-being. Choice C accurately reflects this philosophy's view of health. Choices A, B, and D do not capture the essence of the yin/yang theory. Being able to work and produce, being happy and stable, or caring for others and functioning socially, while important, do not encompass the holistic balance emphasized in the yin/yang theory.
2. Specific gravity in urinalysis:
- A. compares the concentration of urine to that of distilled water
- B. is useless when the patient is dehydrated
- C. can only be measured using a refractometer
- D. None of the above
Correct answer: A
Rationale: Specific gravity in urinalysis measures the concentration of solutes in urine compared to that of distilled water. This comparison helps in assessing the kidney's ability to concentrate urine properly. It is a valuable test even in dehydrated patients as it provides insights into renal function. Specific gravity can be measured using various methods, including a refractometer or reagent strips. Normal specific gravity readings of human urine typically range from 1.005 to 1.030. Choice A is correct as it accurately describes the purpose of specific gravity in urinalysis. Choices B and C are incorrect as specific gravity remains relevant in dehydrated patients and can be measured using different techniques, not solely a refractometer.
3. The healthcare professional is preparing to measure the length, weight, chest, and head circumference of a 6-month-old infant. Which measurement technique is correct?
- A. Measuring the infant's length using a tape measure
- B. Weighing the infant on an electronic standing scale
- C. Measuring the chest circumference at the nipple line with a tape measure
- D. Measuring the head circumference by wrapping the tape measure around the head
Correct answer: C
Rationale: For accurate measurements, specific techniques are required for different parameters in infants. Measuring the chest circumference involves encircling the chest at the nipple line. Length should be measured on a horizontal measuring board. Weight should be measured using a platform-type balance scale. Head circumference measurement entails ensuring the tape is aligned at the eyebrows and prominent frontal and occipital bones for the widest span. Therefore, the correct technique for measuring the chest circumference is at the nipple line with a tape measure. The other options are incorrect because length should be measured on a horizontal board, weight should be measured on a balance scale, and head circumference should be measured around the head, not over the nose and cheekbones.
4. Which of the following safety precautions should the nurse discuss when working with an immunocompromised client?
- A. Avoid canned foods and increase consumption of fresh fruits and vegetables
- B. Hand-wash utensils after use and allow them to air dry
- C. Only drink tap water that has been filtered or boiled before consumption
- D. Never eat meals prepared in restaurants
Correct answer: C
Rationale: The correct answer is to only drink tap water that has been filtered or boiled before consumption. Immunocompromised clients are susceptible to infections, so it is essential to take precautions to prevent exposure to harmful pathogens. Drinking tap water that has been filtered or boiled helps eliminate potential pathogens that could be harmful to the client's health. Choices A, B, and D do not directly address the issue of avoiding potential pathogens that could compromise the health of an immunocompromised client. Thus, they are incorrect. Hand-washing utensils, avoiding canned foods, and increasing fruit and vegetable consumption are good general hygiene practices but may not specifically address the needs of an immunocompromised client.
5. Improper placement of the hands under the rib cage when performing the Heimlich maneuver could result in:
- A. damage to the manubrium of the sternum.
- B. damage to the xiphoid process.
- C. damage to the coccyx.
- D. None of the above is possible, even with improper hand placement.
Correct answer: B
Rationale: The xiphoid process is a small, cartilaginous extension at the inferior end of the sternum. Placing the hands improperly during the Heimlich maneuver too close to this process can result in it breaking off and potentially causing damage to internal organs. Choices A and C are incorrect because the manubrium of the sternum and the coccyx are not in the area where the hands would typically be placed during the Heimlich maneuver.
