1. What are Korotkoff sounds?
- A. Sounds noted during diastole.
- B. The result of the vibration of blood against artery walls while blood pressure readings are being taken.
- C. Sounds only noted by skilled cardiologists.
- D. Distinct sounds which are classified into 6 phases.
Correct answer: B
Rationale: Korotkoff sounds are the sounds that occur when blood flows in an artery that has been temporarily compressed during a blood pressure measurement. These sounds result from the vibration of blood against the artery walls as the pressure cuff is released. There are five distinct phases of Korotkoff sounds, which healthcare providers are trained to identify during blood pressure assessment. The correct answer, choice B, accurately describes the nature of Korotkoff sounds and how they are generated. Choices A, C, and D are incorrect because Korotkoff sounds are not specific to diastole, not limited to skilled cardiologists, and categorized into five phases, not six.
2. When assessing a 75-year-old patient who has asthma, the nurse notes that the patient assumes a tripod position, leaning forward with arms braced on the chair. How would the nurse interpret these findings?
- A. Interpret that the patient is eager and interested in participating in the interview.
- B. Evaluate the patient for abdominal pain, which may be exacerbated in the sitting position.
- C. Interpret that the patient is having difficulty breathing and assist them to a supine position.
- D. Recognize that a tripod position is often used when a patient is having respiratory difficulties.
Correct answer: D
Rationale: Assuming a tripod position"?leaning forward with arms braced on chair arms"?occurs with chronic pulmonary diseases like asthma. This position helps improve breathing by allowing better use of respiratory muscles. Option A is incorrect because assuming the tripod position is not related to being eager or interested in participating in an interview. Option B is incorrect as abdominal pain is not typically associated with the tripod position in this context. Option C is incorrect as assisting the patient to a supine position would not address the underlying respiratory difficulty indicated by the tripod position. Therefore, the correct interpretation is to recognize that the patient is likely experiencing respiratory difficulties when assuming the tripod position.
3. What is the correct action regarding thigh pressure when comparing it to arm pressure in an adolescent with high blood pressure?
- A. The popliteal artery should be auscultated to obtain thigh pressure.
- B. The best position to measure thigh pressure is the prone position.
- C. If the blood pressure in the arm is high in an adolescent, then it should be compared with the thigh pressure.
- D. Thigh pressure is generally higher than arm pressure due to the proximity to the heart and the size of the popliteal vessels.
Correct answer: C
Rationale: When blood pressure measured in the arm is significantly elevated, especially in adolescents and young adults, it is crucial to compare it with thigh pressure to assess for coarctation of the aorta. The popliteal artery, not the femoral artery, should be auscultated for the thigh pressure reading as the femoral artery is closer to the placement of the blood pressure cuff. Generally, thigh pressure is higher than arm pressure; however, if there is coarctation of the artery, arm pressures can be higher than thigh pressures. The preferred position for measuring thigh pressure is the prone position, not supine, with the knee slightly bent to facilitate accurate readings.
4. The nurse is preparing to assess a patient’s abdomen by palpation. How should the nurse proceed?
- A. Avoid palpating reportedly “tender” areas as this may cause pain.
- B. Palpate tender areas quickly to minimize patient discomfort.
- C. Initiate the assessment with deep palpation while encouraging the patient to relax and take deep breaths.
- D. Begin the assessment with light palpation to detect surface characteristics and to acclimate the patient to touch.
Correct answer: D
Rationale: The correct approach is to begin the assessment with light palpation to detect surface characteristics and to acclimate the patient to touch. This allows the nurse to first assess surface features before proceeding to deeper palpation. Starting with light palpation also helps the patient become more comfortable with being touched, creating a smoother examination experience. Palpating tender areas quickly, as suggested in choice B, can increase patient discomfort. Deep palpation, as in choice C, is typically performed after light palpation to avoid discomfort and ensure proper assessment. Avoiding palpation of tender areas first, as in choice A, helps prevent causing unnecessary pain and should be done towards the end of the assessment.
5. Intermittent fevers are:
- A. fevers which come and go.
- B. fevers which rise and fall but are always considered above the patient's average temperature.
- C. fevers which fluctuate more than three degrees and never return to normal.
- D. None of the above.
Correct answer: A
Rationale: Intermittent fevers are characterized by periods of fever followed by periods of normal body temperature. They alternate between being febrile and afebrile. Continuous fevers show minimal fluctuations over a 24-hour period, while remittent fevers fluctuate significantly but do return to normal body temperature. Choice A is correct as it accurately describes intermittent fevers. Choices B and C are incorrect as they do not fully capture the defining characteristic of intermittent fevers, which involve cyclical episodes of fever and normal temperature. Choice D is incorrect as there is a specific definition for intermittent fevers.
