PN ATI Capstone Adult Medical-Surgical 1 Quiz

Correct Answer: B

Rationale: When using the ABC approach to client care, the nurse should identify that the priority intervention is administering oxygen. In this scenario, the client's oxygen saturation is only 91%, which is below the normal range of 95% and above. Oxygen is essential for adequate tissue perfusion and oxygenation of vital organs. Administering oxygen takes precedence over other interventions to ensure the client's physiological needs are met first. Choice A can be addressed after ensuring adequate oxygenation. Choice C is important for preventing postoperative complications but is not as urgent as addressing oxygen saturation. Choice D is a common postoperative intervention, but in this case, ensuring adequate oxygenation is the priority over IV fluid administration.

Correct Answer: D

Rationale: The priority action is to verify the prescription with the provider. Verifying the prescription ensures patient safety by preventing fluid volume overload and dysrhythmias, which can result from infusing potassium too rapidly. Teaching the client about IV extravasation, evaluating IV patency, and consulting with the pharmacist are important but should come after verifying the prescription to ensure the ordered treatment is appropriate and safe for the client's condition.

Correct Answer: B

Rationale: The correct answer is B. The circumference of the upper arm above the insertion site of the PICC should be measured at the time of insertion and then again during assessments. An increase in circumference could indicate deep vein thrombosis, which could be life-threatening. Choice A is not a concern as changing the dressing 7 days ago is within the recommended timeframe. Choice C is not alarming as the catheter not being used for 8 hours does not necessarily indicate a problem. Choice D indicates proper catheter care by flushing it with sterile saline after medication use, so it does not require provider notification.

Correct Answer: B

Rationale: The correct answer is B: Respiratory alkalosis. In this scenario, the client is hyperventilating, leading to excessive elimination of carbon dioxide. As a result, the PaCO2 decreases, causing a decrease in hydrogen ion concentration and an increase in pH, resulting in respiratory alkalosis. Choice A, Respiratory acidosis, is incorrect because the ABG results show a low PaCO2, not an elevated one. Choices C and D, Metabolic acidosis and Metabolic alkalosis, do not align with the ABG results provided, which point towards a respiratory, not metabolic, imbalance.

Correct Answer: B

Rationale: The correct answer is to monitor the client's skin under the halo vest. This is important to assess for signs of skin issues such as excessive sweating, redness, or blistering, which can lead to skin breakdown and infection. Choice A is incorrect because inspecting the pin site every 4 hours is necessary but not the priority in this case. Choice C is incorrect as it is not essential for two personnel to hold the halo device during repositioning. Choice D is incorrect because applying powder frequently can actually increase the risk of skin issues by clogging pores and causing irritation.
