1. What is the fundamental difference between nursing diagnoses and collaborative problems?
- A. Collaborative problems are managed by nurses using physician-prescribed interventions.
- B. Collaborative problems can be addressed by independent nursing interventions.
- C. Physician-prescribed interventions are incorporated into nursing diagnoses.
- D. Nursing diagnoses include physiologic complications that nurses monitor to detect status changes.
Correct answer: B
Rationale: The correct answer is B, as collaborative problems necessitate the collective expertise and skills of numerous healthcare professionals, including nurses. These problems can be dealt with through independent nursing interventions in cooperation with other team members. Option A is incorrect because collaborative problems aren't strictly managed with physician-prescribed interventions. Option C is incorrect because nursing diagnoses aim at identifying and treating actual or potential health issues, rather than merely integrating physician-prescribed interventions. Option D is incorrect because nursing diagnoses aim at identifying patient issues, not solely physiologic complications, and guide the necessary nursing care, not just monitor for changes.
2. Why is a pulse oximeter attached to Mr. Dizon's finger?
- A. To determine if the patient's hemoglobin level is low and if he requires a blood transfusion
- B. To check the level of the patient's tissue perfusion
- C. To measure the effectiveness of the patient's anti-hypertensive medications
- D. To detect oxygen saturation of arterial blood before symptoms of hypoxemia develop
Correct answer: D
Rationale: A pulse oximeter is used to detect the oxygen saturation levels in arterial blood before the onset of hypoxemia symptoms. This device provides essential information about the effectiveness of oxygen transportation to the body's tissues. Choice A is incorrect because a pulse oximeter does not directly measure hemoglobin levels nor determine the need for a blood transfusion. Choice B is incorrect because a pulse oximeter is designed specifically to assess oxygen saturation, not tissue perfusion. Choice C is incorrect because a pulse oximeter is not used to measure the efficacy of anti-hypertensive medications, but rather to monitor oxygen levels in the blood.
3. What term is used to refer to the beliefs, ideals, and values that direct an organization and give it a sense of purpose?
- A. Philosophy
- B. Mission
- C. Vision
- D. Goals and Objectives
Correct answer: C
Rationale: The correct term for the beliefs, ideals, and values that direct an organization and provide it with a sense of purpose is 'Vision'. A Vision statement outlines the organization's aspirations and goals for the future. Choices A, B, and D are incorrect in this context. 'Philosophy' refers to a system of beliefs or principles, 'Mission' relates to the organization's purpose and primary objectives, and 'Goals and Objectives' are the specific targets set to accomplish the Vision.
4. Why is atherosclerosis dangerous to arterial function?
- A. It diminishes central circulation
- B. It causes decreased blood pressure on artery walls
- C. It narrows the arterial lumen so a clot can easily block it
- D. It increases arterial elasticity
Correct answer: C
Rationale: Atherosclerosis is dangerous to arterial function because it narrows the arterial lumen, increasing the risk of a clot completely blocking the blood flow. This can lead to severe cardiovascular events such as heart attacks or strokes. Choice A is incorrect since atherosclerosis does not primarily diminish central circulation, but rather, it impedes local blood flow where the plaque is present. Choice B is also incorrect as atherosclerosis increases the pressure on artery walls due to the narrowed space for blood flow, not decrease it. Lastly, choice D is incorrect as atherosclerosis causes the arteries to lose their elasticity, not increase it.
5. In which type of shock does the patient experience a mismatch of blood flow to the cells?
- A. Distributive
- B. Cardiogenic
- C. Hypovolemic
- D. Septic
Correct answer: A
Rationale: The correct answer is A: Distributive shock. Distributive shock is characterized by a widespread increase in vascular permeability leading to a relative hypovolemia and a mismatch of blood flow to the cells. Choice B, Cardiogenic shock, is due to the heart's inability to pump effectively. Choice C, Hypovolemic shock, results from a decrease in intravascular volume. Choice D, Septic shock, is caused by a systemic response to infection.
