Autoimmunity is defined as a phenomenon involving which of the following?
- A. Production of endotoxins that destroy B
- B. Overproduction of reagin antibody
- C. Depression of the immune response
- D. Inability to differentiate self from nonself
Correct Answer: D
Rationale: Autoimmunity is when the immune system mistakenly attacks the body's own cells. Choice D is correct because it reflects this key feature - the inability to differentiate self from nonself. This leads to the immune system targeting healthy tissues. Choices A, B, and C are incorrect as they do not accurately describe autoimmunity. Choice A refers to endotoxins destroying B cells, which is not the definition of autoimmunity. Choice B mentions overproduction of reagin antibody, which is not related to autoimmunity. Choice C is incorrect as autoimmunity does not involve depression of the immune response but rather an inappropriate immune response.

A client has been diagnosed with type 1 diabetes mellitus. When teaching the client and family how diet and exercise affect insulin requirements, the nurse should include which guideline?
- A. “You’ll need more insulin when you exercise or increase your food intake.”
- B. “You’ll need less insulin when you exercise or reduce your food intake.”
- C. “You’ll need less insulin when you increase your intake.”
- D. “You’ll need more insulin when you exercise or decrease your food intake.”
Correct Answer: A
Rationale: The correct answer is A: “You’ll need more insulin when you exercise or increase your food intake.” In type 1 diabetes, exercise and increased food intake can lead to increased glucose levels, requiring more insulin to maintain blood sugar control. Increasing physical activity can enhance insulin sensitivity, necessitating adjustments in insulin dosage. Choices B, C, and D are incorrect as they do not align with the physiological response in type 1 diabetes. B suggests needing less insulin when exercising, which is inaccurate as physical activity can lower blood sugar levels. C implies needing less insulin with increased food intake, which is incorrect as more food can lead to higher glucose levels. D suggests needing more insulin when decreasing food intake, which is not necessarily true as lower food intake can result in lower glucose levels.
Which method of data collection will the nurse use to establish a patient’s database?
- A. Reviewing the current literature to determine evidence-based nursing actions
- B. Checking orders for diagnostic and laboratory tests
- C. Performing a physical examination
- D. Ordering medications
Correct Answer: C
Rationale: The correct answer is C: Performing a physical examination. This method allows the nurse to collect objective data directly from the patient, which is crucial in establishing a comprehensive patient database. By assessing the patient's physical condition, the nurse can gather vital information such as vital signs, overall health status, and potential areas of concern. Reviewing literature (A) and checking orders for tests (B) may provide additional insights but are not direct data collection methods. Ordering medications (D) is a treatment intervention, not a data collection method.
The nurse is developing a teaching plan for a patient. Which of the following is a modifiable risk factor for the development of hypertension? i.Race iv.Sedentary lifestyle ii.High cholesterol v.Age iii.Cigarette smoking
- A. 1 and 2
- B. 2, 3, 4 and 5
- C. 2, 3 and 4
- D. All of the above
Correct Answer: C
Rationale: The correct answer is C: 2, 3, and 4. High cholesterol, cigarette smoking, and a sedentary lifestyle are modifiable risk factors for developing hypertension. High cholesterol can lead to atherosclerosis, increasing blood pressure. Smoking can constrict blood vessels, raising blood pressure. Sedentary lifestyle can lead to obesity and overall poor cardiovascular health, contributing to hypertension. Race and age are non-modifiable risk factors. Choice A is incorrect because it includes race, a non-modifiable factor. Choice B is incorrect because it includes age, which is also non-modifiable. Choice D is incorrect because it includes all factors, including non-modifiable ones.
A nurse writes the following nursing diagnosis for a client with Alzheimer’s disease: 'Disturbed Thought Processes related to Alzheimer’s disease as evidenced by incoherent language.' Which part of this diagnosis is considered the problem statement?
- A. Disturbed thought processes
- B. Related to
- C. Alzheimer’s disease
- D. Incoherent language
Correct Answer: A
Rationale: The correct answer is A: "Disturbed thought processes." This is the problem statement because it identifies the client's main issue, which is the disturbance in their thought processes. The "related to" part (B) indicates the cause, "Alzheimer's disease" (C) is the etiology, and "incoherent language" (D) is the evidence. By focusing on the problem statement, the nurse can develop appropriate interventions to address the client's disturbed thought processes.
A nurse is using assessment data gathered about a patient and combining critical thinking to develop a nursing diagnosis. What is the nurse doing?
- A. Assigning clinical cues
- B. Defining characteristics
- C. Diagnostic reasoning NursingStoreRN
- D. Diagnostic labeling
Correct Answer: C
Rationale: The correct answer is C: Diagnostic reasoning. The nurse is using assessment data to analyze, interpret, and make a judgement about the patient's condition. This process involves critical thinking skills to develop a nursing diagnosis. Choice A (Assigning clinical cues) is incorrect because it refers to identifying specific signs and symptoms. Choice B (Defining characteristics) is incorrect as it pertains to the features of a diagnosed condition. Choice D (Diagnostic labeling) is incorrect because it focuses on naming a specific nursing diagnosis. Diagnostic reasoning encompasses the entire process of analyzing data, making connections, and formulating a nursing diagnosis based on critical thinking.
