1. Data analysis is to be done and the nurse researcher wants to include variability. These include the following EXCEPT:
- A. Variance C. Standards of Deviation
- B. Range D. Mean
- C.
- D.
Correct answer: A
Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.
2. Which of the following terms describes the amount of blood ejected per heartbeat?
- A. Stroke volume
- B. Cardiac output
- C. Ejection fraction
- D. Afterload
Correct answer: A
Rationale: The correct answer is A: Stroke volume. Stroke volume refers to the amount of blood ejected by the left ventricle in one contraction. Choice B, Cardiac output, is the total volume of blood pumped by the heart per minute and is calculated by multiplying stroke volume by heart rate. Choice C, Ejection fraction, is the percentage of blood pumped out of the left ventricle with each heartbeat. Choice D, Afterload, refers to the pressure or resistance that the ventricles must overcome to eject blood during systole. Therefore, in the context of the question, the term that specifically describes the amount of blood ejected per heartbeat is stroke volume.
3. Reducing the amount of trans fat in the diet is an effective method of decreasing the risk of CHD. Which food is most likely a source of trans fat?
- A. hot dogs
- B. whole milk
- C. fatty fish
- D. potato chips
Correct answer: D
Rationale: The correct answer is D: potato chips. Potato chips, especially when fried in hydrogenated oils, are a common source of trans fats, which are linked to an increased risk of coronary heart disease (CHD). Hot dogs (choice A) can also contain trans fats if made with processed meats and added fats. Whole milk (choice B) and fatty fish (choice C) do not typically contain trans fats, making them less likely sources compared to potato chips.
4. What type of gastrointestinal complication is most likely to be caused by the use of antibiotics to treat H. pylori infection?
- A. Hemoptysis
- B. Altered taste sensation
- C. Flatulence
- D. Bloody stools
Correct answer: B
Rationale: The correct answer is B, Altered taste sensation. The use of antibiotics is known to cause changes in taste sensation as a side effect, especially when used to treat H. pylori infections. Hemoptysis (Choice A) refers to coughing up blood, and while it can be a symptom of various conditions, it is not typically associated with the use of antibiotics. Flatulence (Choice C) and bloody stools (Choice D) can also occur as gastrointestinal complications, but they are not the most likely side effect when treating H. pylori with antibiotics. Therefore, choices A, C, and D are incorrect.
5. Cancers that arise from epithelial tissues are known as:
- A. Leukemias
- B. Myelomas
- C. Carcinomas
- D. Sarcomas
Correct answer: C
Rationale: The correct answer is C: Carcinomas. Carcinomas are cancers that originate from epithelial tissues, which are the tissues lining the surfaces of organs and structures in the body. Leukemias (choice A) are cancers of the blood-forming cells, not epithelial tissues. Myelomas (choice B) are cancers that develop in plasma cells in the bone marrow, not epithelial tissues. Sarcomas (choice D) are cancers that arise from connective tissues like bone, cartilage, or muscle, not epithelial tissues. Therefore, choices A, B, and D are incorrect in the context of cancers originating from epithelial tissues.
