Nursing Process Questions

Correct Answer: C

Rationale: Correct Answer: C - Diffusion Rationale: Diffusion is the movement of a substance from an area of higher concentration to an area of lower concentration. This process occurs naturally to achieve equilibrium. In the context of fluids and electrolytes, this movement helps maintain balance within the body. Unlike osmosis, which involves the movement of water molecules across a semi-permeable membrane, diffusion applies to the movement of all types of substances. Filtration involves the movement of substances through a barrier under pressure, and active transport requires energy to move substances against a concentration gradient. Therefore, the correct answer is diffusion as it aligns with the principle of movement from high to low concentration for achieving equilibrium.

Correct Answer: A

Rationale: The correct answer is A: Inspecting for bleeding or cyanosis. During uterosigmoidostomy, the nurse's critical task is to monitor for any signs of bleeding or cyanosis, which are indicators of potential complications such as hemorrhage or impaired blood flow. This involves observing the surgical site for any abnormal bleeding and assessing the skin color for signs of inadequate oxygenation. Inspecting for symptoms of peritonitis (B) is not directly related to this surgical procedure. Assessing the client's allergy to iodine (C) is important but not a critical task during the procedure. Checking for signs of electrolyte losses (D) is important but not as critical as monitoring for immediate postoperative complications like bleeding or cyanosis.

Correct Answer: B

Rationale: The correct answer is B: Help the client don thromboembolic stocking or support hose during waking hours. This intervention helps decrease the risk for thrombus formation in polycythemia vera by promoting venous return and preventing blood pooling in the lower extremities. Compression stockings improve circulation and reduce the risk of blood clots. Isometric exercises (choice A) may increase blood pressure and heart rate, potentially worsening the risk of thrombus formation. Drinking excess fluid (choice C) can lead to hypervolemia and increase the risk of clotting. Resting immediately if chest pain develops (choice D) is important but does not directly address the prevention of thrombus formation in polycythemia vera.

Correct Answer: A

Rationale: The correct answer is A. In the Snellen eye chart test, the first number (20) represents the distance at which the client is viewing the chart, and the second number (40) represents the distance at which a person with normal vision can read the same line. Therefore, a client with 20/40 vision sees letters at 20 feet that others with normal vision can read at 40 feet. Choices B, C, and D are incorrect because they do not accurately reflect the interpretation of the 20/40 vision result from the Snellen eye chart test. B is incorrect because the client does not see letters at 40 feet that others can read at 20 feet. Choices C and D are incorrect because the Snellen eye chart test measures visual acuity, not color perception.

Correct Answer: A

Rationale: The correct answer is A: Risk for impaired skin integrity. Myocardial infarction, hypertension, and progressive systemic sclerosis can lead to impaired circulation and skin breakdown. Clients with these conditions are at risk for pressure ulcers due to decreased blood flow and compromised skin integrity. The other options, B: Imbalanced nutrition, C: Constipation, and D: Ineffective thermoregulation, do not directly relate to the client's conditions or the potential complications associated with them. Therefore, the most appropriate nursing diagnosis for this client would be A: Risk for impaired skin integrity.
