LPN Fundamentals Questions Questions
Question 1 of 5
The following are correct actions when taking radial pulse except:
Correct Answer: B
Rationale: Using the thumb to palpate radial pulse is wrong e.g., its pulse interferes unlike fingers (index, middle) on wrist, palm down, assessing rate, rhythm, volume, symmetry. Nurses avoid this e.g., training for accurate measurement, per skills.
Question 2 of 5
Which of the following is not a characteristic of a normal urine?
Correct Answer: B
Rationale: Normal urine pH is 4.5-8 e.g., averages 6 but varies not fixed at 6. Clear, aromatic, yellow-amber are true. Nurses assess e.g., pH for health, per norms.
Question 3 of 5
The endocrine pancreas is responsible for the regulation of
Correct Answer: A
Rationale: The endocrine pancreas regulates sugar e.g., insulin lowers glucose unlike sodium/potassium (adrenals), calcium (parathyroid). Nurses assess e.g., BS for function, per endocrine.
Question 4 of 5
Which theory emphasizes the relationships between the whole and the parts, and describes how parts function and behave?
Correct Answer: C
Rationale: General systems theory, developed by Ludwig von Bertalanffy, explores how wholes and their parts interact, describing the function and behavior of components within a system. In nursing, it views the client as a system body, mind, and spirit interacting with environments like family or healthcare settings, emphasizing interdependence. Nursing theory broadly aims to explain and predict care outcomes, not specifically parts-whole dynamics. Adaptation theory, per Roy, focuses on adjusting to stimuli, while developmental theory tracks growth stages, neither prioritizing systemic relationships. General systems theory's holistic lens aids nurses in understanding how a client's physical decline affects emotional health or how family dynamics influence recovery. Its interdisciplinary roots make it versatile, guiding comprehensive care plans that address interconnected factors, enhancing nursing's ability to manage complex client needs effectively.
Question 5 of 5
A nurse researcher is examining the cause-and-effect relationship between the consumption of tap water containing minimal amounts of bleach, and the incidence of cancer in rats. The research is taking place in a laboratory setting. What type of quantitative research is being used based upon this description?
Correct Answer: D
Rationale: Experimental research, used here, tests cause-and-effect under controlled conditions, typically in labs. The nurse manipulates tap water with bleach (independent variable) to measure cancer incidence in rats (dependent variable), controlling factors like diet to isolate effects. Descriptive research observes phenomena like disease prevalence without manipulation. Correlational research examines variable relationships, like smoking and cancer rates, without causation. Quasi-experimental research tests cause-effect but lacks full control, often outside labs. Experimental design's rigor randomization, controls yields causal insights, like bleach's oncogenicity, advancing nursing's scientific base. This method's precision suits lab settings, offering clear, replicable evidence for health impacts, critical for informing practice or policy.
