1. Why should a palpated pressure be performed before auscultating blood pressure?
- A. To more clearly hear the Korotkoff sounds.
- B. To detect the presence of an auscultatory gap.
- C. To avoid missing a falsely elevated blood pressure.
- D. To more readily identify phase IV of the Korotkoff sounds.
Correct answer: B
Rationale: Performing a palpated pressure before auscultating blood pressure helps in detecting the presence of an auscultatory gap. An auscultatory gap is a period during blood pressure measurement when Korotkoff sounds temporarily disappear before reappearing. Inflation of the cuff 20 to 30 mm Hg beyond the point where a palpated pulse disappears helps in identifying this gap. This technique ensures accurate blood pressure measurement by preventing the underestimation of blood pressure values. The other options are incorrect because palpating the pressure is not primarily done to hear Korotkoff sounds more clearly, avoid missing falsely elevated blood pressure, or readily identify a specific phase of Korotkoff sounds.
2. When reviewing the demographics of ethnic groups in the United States, which group does the nurse recall as the largest and fastest-growing population?
- A. Asian
- B. Hispanic
- C. American Indian
- D. African American/Black
Correct answer: B
Rationale: The correct answer is 'Hispanic.' Hispanics are the largest and fastest-growing population in the United States. While African Americans/Blacks, Asians, American Indians, and other groups are significant, Hispanics currently represent the largest demographic group. African American/Black, Asian, and American Indian populations are substantial but not as large or fast-growing as the Hispanic population. Therefore, Hispanic is the most appropriate choice in this scenario.
3. A patient has come to the office for a blood draw. The patient starts to sweat and is very anxious. Which of the following would be the BEST way to proceed?
- A. Do not perform the procedure. Notify the physician of the reason why.
- B. Perform the procedure but pay close attention for signs of potential syncope.
- C. Allow the patient to reschedule for a time when he isn't as anxious.
- D. Have the physician draw the blood.
Correct answer: B
Rationale: In the scenario where a patient is sweating and anxious, it is important to assess for signs of potential syncope (fainting) while proceeding with the blood draw. If the patient does not exhibit signs of fainting, the phlebotomy procedure can be performed safely. Postponing the procedure may not address the patient's anxiety and inconvenience them. Having the physician draw the blood is not necessary if the phlebotomist can handle the situation effectively.
4. The supervising RN asks you to bring the unit's collected lab specimens to the lab 'stat'. You should ______________.
- A. not decline this task because nurses do not handle 'stats'.
- B. run this errand as promptly as possible
- C. run this errand immediately and without delay
- D. Complete this task before the end of your shift or after your lunch.
Correct answer: C
Rationale: In healthcare settings, 'stat' is commonly used to indicate that something should be done immediately and without any delay. It is a critical term used to prioritize urgent tasks. Nurses are responsible for various tasks, including handling urgent requests such as transporting lab specimens promptly. Option A is incorrect as nurses can handle urgent tasks like 'stats'. Option B is not as specific as option C, which clearly emphasizes the need for immediate action. Option D is incorrect as it suggests delaying the task until later, which goes against the urgency implied by the term 'stat'.
5. Over a patient's lifespan, how does the pulse rate change?
- A. starts out fast and decreases as the patient ages.
- B. starts out slower and increases as the patient ages.
- C. varies from slow to fast throughout the lifespan.
- D. stays consistent from birth to death.
Correct answer: A
Rationale: The correct answer is that the pulse rate starts out fast and decreases as the patient ages. In infants, the normal pulse rate is around 140 beats per minute, which then falls to an average of 80 beats per minute in adults. As individuals age, their pulse rate tends to decrease due to changes in cardiovascular function. Choice B is incorrect as the pulse rate typically decreases with age, rather than increases. Choice C is incorrect as there is a general trend of decreasing pulse rate as individuals age, rather than a continuous variation. Choice D is incorrect as the pulse rate does change over a patient's lifespan, starting fast in infants and decreasing as they age.
