ATI Exit Exam RN

Correct Answer: B

Rationale: In chronic obstructive pulmonary disease, there is impaired gas exchange, leading to retention of carbon dioxide (CO2) and subsequent respiratory acidosis. A PaCO2 of 55 mm Hg is higher than the normal range (35-45 mm Hg) and is indicative of respiratory acidosis in COPD. Choices A, C, and D are not typically associated with COPD. PaO2 may be decreased, HCO3 may be elevated to compensate for acidosis, and pH may be lower than 7.35 due to respiratory acidosis in COPD.

Correct Answer: D

Rationale: Corrected Rationale: Chicken breast is an excellent source of protein, which is essential for wound healing due to its role in tissue repair and regeneration. Fish is also a good source of protein, but chicken breast is a more commonly recommended option for wound healing due to its high protein content and lower fat content compared to some types of fish. Bananas and white bread, on the other hand, are not high-protein foods and do not provide the necessary nutrients for wound healing.

Correct Answer: D

Rationale: The correct instruction the nurse should include for a client prescribed digoxin is to notify the provider if they experience nausea or visual changes, as these symptoms can indicate digoxin toxicity. Option A is incorrect because digoxin should be taken on an empty stomach for better absorption. Option B is incorrect as antacids can interfere with the absorption of digoxin. Option C is incorrect as taking digoxin based on heart rate alone is not appropriate.

Correct Answer: B

Rationale: The correct answer is Hypokalemia. Hypokalemia is the most concerning electrolyte imbalance for a patient receiving digoxin because it can increase the risk of digoxin toxicity. Low potassium levels can potentiate the effects of digoxin on the heart, leading to serious cardiac arrhythmias. Hyperkalemia (Choice A) is not typically associated with digoxin use. Hyponatremia (Choice C) and Hypercalcemia (Choice D) are not directly related to digoxin therapy and do not pose the same risk of toxicity.

Correct Answer: A

Rationale: The correct answer is A: Check the central line site daily. Monitoring the central line site daily is crucial in detecting early signs of infection, such as redness, swelling, tenderness, or drainage. By checking the site regularly, healthcare providers can take prompt action to prevent complications. Choice B, monitoring the patient's vital signs, while important in assessing overall health, may not specifically indicate an infection related to the central line. Choice C, checking the central line dressing every other day, may not be frequent enough to catch early signs of infection. Choice D, checking for signs of sepsis, is important but represents a more severe stage of infection and may occur after local signs at the central line site have already manifested.
