Question 1 of 5
In a research study, a variable that is manipulated by the researcher is called:
Correct Answer: B
Rationale: The correct answer is B: Independent variable. The independent variable is the one that the researcher manipulates or controls to observe its effect on the dependent variable. It is the cause in a cause-and-effect relationship. The dependent variable, on the other hand, is the outcome that is measured and affected by the independent variable. Control variables are factors that are held constant to prevent them from influencing the results. Moderating variables are factors that can influence the relationship between the independent and dependent variables, but they are not directly manipulated by the researcher in the study.
Question 2 of 5
A nurse is serving on a continuous quality improvement (CQI) committee that has been assigned to develop a program to reduce the number of medication administration errors following a sentinel event at the facility. Which of the following strategies should the committee plan to initiate first?
Correct Answer: C
Rationale: The correct answer is C: Review the events leading up to each medication administration error. This should be initiated first because it allows the committee to identify root causes of errors and implement targeted interventions. By understanding the sequence of events, the committee can uncover system weaknesses or breakdowns that contribute to errors. A: Providing an inservice may be helpful, but without understanding the specific factors leading to errors, it may not address the underlying issues causing the errors. B: Requiring a competency exam is important, but addressing the system failures that lead to errors should take priority to prevent future errors. D: Developing a quality improvement program is necessary, but without a thorough understanding of the events leading to errors, the program may not effectively target the root causes of errors.
Question 3 of 5
Deep palpation
Correct Answer: A
Rationale: The correct answer is A, using 2 hands for deep palpation. Deep palpation requires more pressure and depth to assess internal organs or structures. Using 2 hands allows for better control, even pressure distribution, and more thorough examination. Using 2 fingers (option B) may not provide enough force for deep palpation, while options C and D are incomplete choices. In summary, using 2 hands is the best approach for deep palpation due to its effectiveness in applying sufficient pressure and achieving accurate results.
Question 4 of 5
Patient with airborne disease, correct
Correct Answer: B
Rationale: The correct answer is B (Above 3 feet in radius) because airborne diseases can spread through respiratory droplets that can travel farther than 3 feet. This is particularly important for diseases like COVID-19 and tuberculosis. Choice A (3 feet in radius) is incorrect as it underestimates the distance respiratory droplets can travel. Choices C and D are incomplete and do not provide a clear answer. Remember, maintaining a safe distance, wearing masks, and proper ventilation are key in preventing the spread of airborne diseases.
Question 5 of 5
Blood pressure, palpatory
Correct Answer: B
Rationale: The correct answer is B because palpating blood pressure allows for assessing the systolic pressure accurately by feeling the pulse disappear and reappear. Diastolic pressure is not accurately determined by palpation alone. Choice A is incorrect because palpation does not provide a reliable method for determining diastolic pressure. Choices C and D are empty and do not offer any valid explanation for palpatory blood pressure readings.
