1. What does an individual who believes in the magicoreligious theory of illness and disease think is the cause of illness?
- A. Germs and viruses
- B. Supernatural forces
- C. Eating imbalanced (hot/cold) foods
- D. Imbalance within his or her spiritual nature
Correct answer: B
Rationale: Individuals who adhere to the magicoreligious theory of illness and disease attribute the cause of illness to supernatural forces. In this perspective, the world is perceived as governed by supernatural forces that influence the well-being of individuals. The belief is that these forces can bring about both good and evil outcomes. Choices A, C, and D are incorrect. Germs and viruses are associated with the biomedical theory of illness. Eating imbalanced hot or cold foods is linked to the yin/yang naturalist theory. Imbalance within one's spiritual nature is not a recognized cause of illness in any of the established theories of illness.
2. A patient is having difficulty understanding how to properly run her glucose meter. Which of the following teaching methods would best help the patient understand how to use her instrument correctly?
- A. Give the patient an instruction booklet and encourage her to call the office if she has questions.
- B. Tell the patient to ask a healthcare provider to demonstrate how to use the instrument.
- C. Have the patient watch a video demonstrating the use of the instrument.
- D. Demonstrate the proper use of the instrument and then have the patient perform the process while still in the office.
Correct answer: D
Rationale: By using a demonstration and performance method of patient education, the patient is offered a chance to perform a task and have learning assessed while still in the office. This ensures that any questions that the patient has can be answered immediately, and any performance issues observed by the medical assistant can also be corrected promptly. Choice A is not as effective as providing a demonstration in person, as it may not address the patient's specific learning needs or allow for immediate feedback. Choice B suggests asking a healthcare provider to demonstrate, which is similar to the correct answer but may not always be readily available in the office. Choice C, watching a video, lacks the interactive component and immediate feedback that a live demonstration provides, making it less effective in this scenario.
3. The nurse receives change-of-shift report on the following four patients. Which patient should the nurse assess first?
- A. A 23-year-old patient with cystic fibrosis who has pulmonary function testing scheduled
- B. A 46-year-old patient on bed rest who is complaining of sudden onset of shortness of breath
- C. A 77-year-old patient with tuberculosis (TB) who has four antitubercular medications due in 15 minutes
- D. A 35-year-old patient who was admitted the previous day with pneumonia and has a temperature of 100.2 F (37.8 C)
Correct answer: B
Rationale: The correct answer is the 46-year-old patient on bed rest who is complaining of sudden onset of shortness of breath. Patients on bed rest who are immobile are at high risk for deep vein thrombosis (DVT). Sudden onset of shortness of breath in a patient with a DVT suggests a pulmonary embolism, which requires immediate assessment and action such as oxygen administration to maintain adequate oxygenation. The other patients should also be assessed as soon as possible, but they do not present with an immediate life-threatening condition that requires urgent intervention like the patient experiencing sudden shortness of breath.
4. The nurse is taking an initial blood pressure reading on a 72-year-old patient with documented hypertension. How should the nurse proceed?
- A. Cuff should be placed on the patient's arm and inflated 30 mm Hg above the point at which the palpated pulse disappears.
- B. Cuff should be inflated to 200 mm Hg in an attempt to obtain the most accurate systolic reading.
- C. Cuff should be inflated 30 mm Hg above the patient's pulse rate.
- D. After confirming the patient's previous blood pressure readings, the cuff should be inflated 30 mm Hg above the highest systolic reading recorded.
Correct answer: C
Rationale: When measuring blood pressure, it's important to account for the possibility of an auscultatory gap, which occurs in about 5% of individuals, particularly those with hypertension due to a noncompliant arterial system. To detect an auscultatory gap, the cuff should be inflated 20 to 30 mm Hg beyond the point at which the palpated pulse disappears. This ensures an accurate measurement of blood pressure by overcoming the potential gap in sounds. Choice A is correct as it follows this guideline. Choices B and C are incorrect because inflating the cuff to 200 mm Hg or above the patient's pulse rate does not address the specific issue of an auscultatory gap. Choice D is incorrect as it focuses on the patient's previous readings rather than the current measurement technique needed to detect an auscultatory gap.
5. Patients exhibiting signs of cyanosis will:
- A. show signs of hyperoxia.
- B. have increased O2 saturation.
- C. have blood levels of CO2 higher than O2 levels.
- D. None of the above.
Correct answer: C
Rationale: Cyanosis is a bluish discoloration of the skin and mucous membranes resulting from low blood oxygen levels. When a patient exhibits cyanosis, it indicates that their blood is poorly oxygenated, leading to a higher concentration of CO2 compared to oxygen. Options A and B are incorrect as cyanosis is associated with low oxygen levels, not hyperoxia or increased O2 saturation. Therefore, the correct answer is that patients exhibiting cyanosis will have blood levels of CO2 higher than O2 levels.
