PN ATI Capstone Proctored Comprehensive Assessment 2020 A with NGN

Correct Answer: C

Rationale: Inadequate peripheral circulation can cause a low pulse oximetry reading by limiting blood flow to the area being measured, leading to inaccurate oxygen saturation readings. Hyperthermia (choice A) is an elevated body temperature and does not directly affect pulse oximetry readings. An increased hemoglobin level (choice B) would actually lead to higher oxygen-carrying capacity in the blood, resulting in normal or increased pulse oximetry readings. Low altitudes (choice D) typically do not cause low pulse oximetry readings unless there are other underlying conditions affecting oxygen levels.

Correct Answer: C

Rationale: In a client with COPD, the nurse should assess for the use of accessory muscles. This is important because COPD can lead to increased work of breathing, causing the client to engage accessory muscles to help with respiration. Assessing for the use of accessory muscles provides crucial information about the client's respiratory effort. Respiratory rate (Choice A) is a standard assessment parameter but may not specifically indicate the severity of COPD. Chest pain (Choice B) is not typically associated with COPD unless there are complicating factors. Oxygen saturation (Choice D) is essential to monitor in COPD clients, but assessing for the use of accessory muscles takes priority as it directly reflects the client's respiratory status in COPD.

Correct Answer: D

Rationale: When a client is receiving corticosteroids, the nurse should monitor both blood glucose levels and blood pressure. Corticosteroids can elevate blood glucose levels, leading to hyperglycemia, and may cause hypertension. Monitoring these parameters is essential to detect and address any potential adverse effects promptly. While monitoring serum potassium levels is important in some situations, it is not a primary concern when caring for a client receiving corticosteroids. Therefore, choices A and B are the most appropriate options for monitoring in this scenario, making option D the correct answer.

Correct Answer: B

Rationale: The correct first action the nurse should take when preparing to administer a blood transfusion is to verify the blood type and crossmatch. This step is crucial to ensure compatibility and prevent transfusion reactions. Obtaining the client's consent is important but should follow the verification process. Taking baseline vital signs is necessary before starting the transfusion, but confirming compatibility takes precedence. Priming the IV with normal saline is a step done before starting the transfusion, after ensuring blood compatibility.

Correct Answer: A

Rationale: The correct answer is A: PT and INR. Warfarin is an anticoagulant that affects the clotting mechanism by inhibiting vitamin K-dependent clotting factors. The PT (Prothrombin Time) and INR (International Normalized Ratio) are specific laboratory values used to monitor the effectiveness and safety of warfarin therapy. These values help healthcare providers adjust the warfarin dosage to maintain the desired level of anticoagulation. Choices B, C, and D are incorrect because blood glucose levels, complete blood count (CBC), and platelet count are not directly monitored to assess the effects of warfarin therapy.
