1. When auscultating the blood pressure of a 25-year-old patient, the nurse notices that the phase I Korotkoff sounds begin at 200 mm Hg. At 100 mm Hg, the Korotkoff sounds muffle. At 92 mm Hg, the Korotkoff sounds disappear. How should the nurse record this patient's blood pressure?

A. 200/92
B. 200/100
C. 100/200/92
D. 200/100/92

Correct answer: A

Rationale: When auscultating blood pressure, it is crucial to note the points at which Korotkoff sounds change. In adults, the last audible sound indicates the diastolic pressure. In this case, the Korotkoff sounds muffle at 100 mm Hg and disappear at 92 mm Hg. Therefore, the blood pressure should be recorded as systolic/diastolic, which is 200/92. Choices B, C, and D are incorrect because they do not reflect the correct points where the Korotkoff sounds change during blood pressure measurement.

2. Which of the following is an organizational factor that affects workplace violence directed at nurses?

A. Clients who have short hospital stays
B. The presence of security guards
C. Restricted client areas
D. Understaffing of nursing personnel

Correct answer: D

Rationale: Understaffing of nursing personnel is a critical organizational factor that can contribute to workplace violence directed at nurses. When there are too few nurses on duty due to understaffing, it can lead to delays in care delivery and inadequate attention to clients' needs. This situation can result in heightened frustration, aggression, or violence from clients or their families towards the nursing staff. On the other hand, the presence of security guards (Choice B) may enhance safety in the workplace and deter violence, making it an incorrect choice. Clients who have short hospital stays (Choice A) and restricted client areas (Choice C) are not directly linked to organizational factors that promote workplace violence against nurses, making them incorrect choices.

3. In which of these patients would rectal temperatures be measured?

A. Older adult
B. Critically ill patient
C. School-age child
D. Patient receiving oxygen via nasal cannula

Correct answer: B

Rationale: Rectal temperature measurement is preferred in situations where other routes are impractical or when the most accurate measure is necessary, such as in critically ill patients. The rectal route may be chosen due to its reliability in such cases. For older adults, school-age children, and patients receiving oxygen via nasal cannula, rectal temperature measurement is not typically indicated. Other routes like oral, tympanic, or axillary measurements are more commonly used in these populations due to comfort, convenience, and non-invasive nature.

4. 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.

5. 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.
