1. After a class on culture and ethnicity, the new graduate nurse reflects a correct understanding of the concept of ethnicity with which statement?
- A. "Ethnicity is dynamic and ever-changing."?
- B. "Ethnicity is the belief in a higher power."?
- C. "Ethnicity pertains to a social group that may possess shared traits such as religion and language."?
- D. "Ethnicity is learned from birth through the processes of language acquisition and socialization."?
Correct answer: C
Rationale: Ethnicity pertains to a social group that may possess shared traits such as common geographic origin, migratory status, religion, language, values, traditions, or symbols and food preferences. Culture is dynamic, ever-changing, and learned from birth through the processes of language acquisition and socialization. Religion is the belief in a higher power. Ethnicity pertains to a social group within the social system that claims to have variable traits, such as a common geographic origin, migratory status, religion, race, language, values, traditions, symbols, or food preferences.
2. 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.
3. 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.
4. When considering the concepts related to blood pressure, which statement best describes the concept of mean arterial pressure (MAP)?
- A. MAP is the pressure of the arterial pulse.
- B. MAP reflects the stroke volume of the heart.
- C. MAP is the pressure forcing blood into the tissues, averaged over the cardiac cycle.
- D. MAP is an average of the systolic and diastolic blood pressures and reflects tissue perfusion.
Correct answer: C
Rationale: Mean Arterial Pressure (MAP) is the pressure that forces blood into the tissues, averaged over the cardiac cycle. It is not the pressure of the arterial pulse (Choice A), nor does it directly reflect the stroke volume of the heart (Choice B). While MAP involves systolic and diastolic pressures, it is not simply an average of these two values as diastole lasts longer. Instead, MAP is closer to diastolic pressure plus one third of the pulse pressure. The best description of MAP is that it represents the pressure forcing blood into the tissues, averaged over the cardiac cycle.
5. Which of the following is a disadvantage of using a dry heat application?
- A. Dry heat is more likely to cause burns than moist heat
- B. Dry heat does not penetrate deeply into the tissues
- C. Dry heat causes the skin to dry out more quickly
- D. Dry heat can quickly cause skin breakdown
Correct answer: C
Rationale: The correct answer is that dry heat causes the skin to dry out more quickly. When comparing dry and moist heat applications, dry heat is less likely to cause burns and skin breakdown. However, one of the disadvantages of dry heat is that it does not penetrate deeply into the tissues and may lead to faster drying out of the skin. This can have negative effects on skin integrity and overall comfort during therapy. Choice A is incorrect because dry heat is less likely to cause burns than moist heat. Choice B is incorrect as dry heat may not penetrate deeply into tissues. Choice D is incorrect as dry heat is less likely to cause skin breakdown compared to moist heat.
