Fundamentals of Nursing Nursing Process Questions

Correct Answer: C

Rationale: The correct answer is C because decreased pulse rate and widened pulse pressure are not signs of hypovolemia. In hypovolemia, the body tries to compensate by increasing the heart rate and narrowing the pulse pressure to maintain adequate blood flow. A is incorrect as dry mucous membranes and soft eyeballs are signs of dehydration. B is incorrect as increased hematocrit and hemoglobin are indicators of hemoconcentration in hypovolemia. D is incorrect as increased lethargy and confusion can be seen in severe hypovolemia due to poor perfusion of vital organs.

Correct Answer: B

Rationale: Step 1: Providing a solution of hydrogen peroxide and water as a mouth rinse helps in reducing the pain of stomatitis by promoting oral hygiene and preventing infections. Step 2: Hydrogen peroxide has antimicrobial properties that can help in reducing bacteria in the mouth, which can worsen stomatitis. Step 3: Rinsing with this solution can also help in cleansing the oral mucosa and reducing inflammation, thereby decreasing pain. Step 4: This intervention directly addresses the nursing diagnosis of impaired oral mucous membrane and is focused on symptom management. Summary: A: Recommending the client to discontinue chemotherapy is not a feasible option as it is essential for treating cancer. C: Monitoring platelet and leukocyte counts is important but does not directly address the pain of stomatitis. D: Checking for signs and symptoms is necessary but does not provide direct relief for the pain of stomatitis.

Correct Answer: C

Rationale: The correct answer is C: Diagnostic reasoning. The nurse is utilizing assessment data to analyze and interpret the information to develop a nursing diagnosis. This involves critical thinking skills to make conclusions and create a plan of care. A: Assigning clinical cues - This choice is incorrect as it refers to identifying objective and subjective data during assessment, not the process of analyzing and synthesizing data to form a diagnosis. B: Defining characteristics - This choice is incorrect as it typically refers to the specific manifestations or symptoms associated with a particular nursing diagnosis, not the process of diagnosing itself. D: Diagnostic labeling - This choice is incorrect as it refers to the final step in the nursing diagnosis process where the nurse assigns a label to the identified problem, not the overall process of diagnostic reasoning.

Correct Answer: C

Rationale: The correct answer is C: 5% dextrose in 0.9% NaCl. This solution is hypertonic because it has a higher osmolarity compared to the other choices. The presence of dextrose and NaCl in this solution increases its solute concentration, causing water to move out of the cells by osmosis. Normal saline (A) and 0.45% NaCl (B) are isotonic solutions, meaning they have the same osmolarity as body fluids. 0.225% NaCl (D) is a hypotonic solution with lower osmolarity than body fluids.

Correct Answer: B

Rationale: Step 1: Crowded living conditions do not directly increase the risk of lung cancer. Step 2: Passive smoke (choice A) and air pollution (choice C) contain carcinogens linked to lung cancer. Step 3: Diet low in fruits and vegetables (choice D) may lead to poor immune function, potentially impacting cancer risk. Step 4: In summary, crowded living conditions do not contribute to lung cancer risk compared to the other choices.
