Nursing Process 1 Test Questions

Correct Answer: A

Rationale: The correct answer is A because green leafy vegetables and soybeans are high in Vitamin K, which counteracts the anticoagulant effect of warfarin. Warfarin works by inhibiting Vitamin K-dependent clotting factors in the liver. By consuming Vitamin K-rich foods, the medication's effectiveness is reduced, leading to an increased risk of blood clot formation. Choices B, C, and D are incorrect because they do not address the specific interaction between Vitamin K and warfarin in affecting coagulation. Choice B suggests the opposite effect of what actually occurs. Choices C and D are irrelevant to the pharmacological mechanism of warfarin.

Correct Answer: A

Rationale: The correct answer is A: abdominal pain related to decreased peristalsis. Ulcerative colitis causes inflammation and ulcers in the colon, leading to abdominal pain due to decreased peristalsis. This impairs the movement of stool through the colon, resulting in pain. Choice B is incorrect as diarrhea is a common symptom of ulcerative colitis, not hyperosmolar intestinal contents. Choice C is incorrect as ulcerative colitis often leads to diarrhea and not fluid volume excess. Choice D is incorrect as activity intolerance is not directly related to ulcerative colitis, whereas abdominal pain is a common symptom associated with the condition.

Correct Answer: A

Rationale: The correct answer is A: Oxygen. Oxygen is primarily transported in the blood bound to hemoglobin within red blood cells, not dissolved in plasma. Carbon dioxide is transported in plasma. Nutrients and hormones are also transported in plasma. Therefore, choice A is incorrect as oxygen is not primarily transported in plasma.

Correct Answer: C

Rationale: The correct answer is C: Increased comfort. Radiation therapy for lung cancer aims to alleviate symptoms, reduce pain, and improve quality of life. It is not typically used as a curative treatment like surgery or chemotherapy (A). It does not prevent the need for oxygen (B), as lung cancer can still affect lung function. While radiation therapy may help control the growth of cancer cells, it is not always effective in preventing cancer spread (D). Therefore, the most appropriate expectation of radiation therapy for lung cancer is increased comfort for the patient.

Correct Answer: A

Rationale: Correct Answer: A (Independent intervention) Rationale: 1. Independent interventions are actions that nurses can initiate without a doctor's order. 2. Teaching a client how to administer insulin falls under the scope of nursing practice. 3. Nurses have the knowledge and authority to educate clients on self-care management. 4. This intervention does not require collaboration with other healthcare providers. Summary: B: Dependent interventions require a doctor's order. C: Interdependent interventions involve collaboration with other healthcare providers. D: Collaborative interventions involve working with other healthcare professionals.
