1. What is the first step in the scientific method?
- A. Conduct an experiment
- B. Make an observation and ask a question
- C. Formulate a hypothesis
- D. Reach a consensus
Correct answer: B
Rationale: The first step in the scientific method is to make an observation and ask a question. This is because the scientific method is a systematic process of investigation that begins with observing a phenomenon or asking a question about it. This is followed by formulating a hypothesis (Choice C), designing and conducting an experiment to test the hypothesis (Choice A), and analyzing the results to reach a consensus or conclusion (Choice D). Therefore, choices A, C, and D are incorrect as they represent steps that occur after the initial observation and question.
2. In a therapeutic relationship, the nurse must understand own values, beliefs, feelings, prejudices & how these affect others. This is called:
- A. Therapeutic use of self
- B. Psychotherapy
- C. Therapeutic communication
- D. Self awareness
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.
3. After a few hours in the Emergency Room, Mr. Dizon is admitted to the ward with an order of hourly monitoring of blood pressure. The nurse finds that the cuff is too narrow and this will cause the blood pressure reading to be:
- A. inconsistent
- B. low systolic and high diastolic
- C. higher than what the reading should be
- D. lower than what the reading should be
Correct answer: C
Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.
4. A nurse is caring for four clients. The nurse should plan to administer total parenteral nutrition for which of the following clients?
- A. A client who is postoperative following a laminectomy and is receiving IV PCA
- B. A client who has dysphagia and does not recognize his family
- C. A client who has COPD and is going home with oxygen
- D. A client who has colon cancer and will undergo a hemicolectomy
Correct answer: D
Rationale: Total parenteral nutrition (TPN) is essential for clients undergoing significant surgical procedures like a hemicolectomy to ensure they receive adequate nutrition when oral intake is not possible. Choices A, B, and C do not typically require TPN. Choice A is managing postoperative pain with IV PCA, choice B is likely to need alternative feeding methods due to dysphagia, and choice C is going home with oxygen for COPD management, which does not directly relate to the need for TPN.
5. 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.
