ATI Capstone Fundamentals Assessment Proctored

Correct Answer: B

Rationale: A pulse deficit is a crucial finding in clients with dysrhythmias as it indicates ineffective cardiac contractions. A pulse deficit occurs when the apical heart rate is faster than the radial pulse rate, suggesting that some heartbeats are not generating a pulse. This can be a sign of serious heart conditions like atrial fibrillation or heart failure. The other options, such as an increased heart rate (choice A), elevated blood pressure (choice C), and bounding pulse (choice D), do not specifically indicate ineffective cardiac contractions and are not directly associated with dysrhythmias.

Correct Answer: A

Rationale: Corrected Rationale: The nurse should instruct the client to use pursed-lip breathing during activities to help improve oxygenation. Pursed-lip breathing can keep the airways open longer, facilitating better oxygen exchange and making it easier to exhale carbon dioxide. Choice B is incorrect as physical activity, within the client's limitations, is beneficial for maintaining overall health. Choice C is incorrect as weight-bearing exercises are important for bone health but not directly related to improving oxygenation in COPD. Choice D is incorrect as using a humidifier while sleeping can help with moisture in the airways but does not directly impact oxygenation in COPD.

Correct Answer: C

Rationale: The correct answer is C because placing a clean dressing over the saturated one helps maintain wound integrity and prevents further tissue damage. Choice A is incorrect as applying direct pressure to the wound is correct for controlling bleeding but not for dressing changes. Choice B is incorrect because removing dressings may disrupt wound healing and increase the risk of infection. Choice D is incorrect since applying alcohol to the wound can cause further irritation and damage to the tissues.

Correct Answer: B

Rationale: Bowel inflammation can reduce the absorption of oral medications, leading to decreased effectiveness. In this case, the decrease in the effectiveness of the arthritis medication could be attributed to impaired absorption due to bowel inflammation. Choices A, C, and D are incorrect because increased activity level, long-term use of the medication, and history of dehydration are not directly associated with a decrease in medication effectiveness related to absorption issues.

Correct Answer: B

Rationale: The correct lifestyle modification that the nurse should emphasize for a client with hypertension is to increase fluid intake to 2 liters per day. Proper hydration helps manage hypertension by supporting kidney function in regulating blood pressure and by diluting sodium levels in the body. Decreasing potassium intake (Choice A) is not recommended, as potassium-rich foods like fruits and vegetables are beneficial for blood pressure control. Avoiding foods high in calcium (Choice C) is not directly related to managing hypertension, and increasing sodium intake (Choice D) is contraindicated as excess sodium can elevate blood pressure.
