ATI PN Adult Medical Surgical 2019

Correct Answer: B

Rationale: The best action for the nurse to take in this situation is to help the client directly contact the HMO to seek information about limitations of coverage. This approach addresses the client's immediate concerns and clarifies the situation, enabling the client to understand the coverage and potential outcomes regarding the bone marrow transplant. Choice A is not the best option as having the healthcare provider write a letter may not provide immediate clarification on coverage. Choice C is inappropriate as legal action should be considered as a last resort, and choice D involving the state board of insurance is not necessary at this initial stage of addressing the client's concern.

Correct Answer: C

Rationale: Raynaud's phenomenon is characterized by vasospasm, leading to episodes of cyanosis (bluish discoloration) and pallor (pale color) in the fingers or toes, often triggered by cold temperatures or stress. This occurs due to the reduced blood flow during vasospastic episodes, causing the discoloration. Choices A, B, and D are incorrect findings associated with other conditions and are not typical of Raynaud's phenomenon.

Correct Answer: C

Rationale: Epoetin alfa is a medication that stimulates red blood cell production. Therefore, in a client with chronic renal failure, an effective outcome of epoetin alfa therapy would be an improvement in hemoglobin levels. This indicates that the medication is working as intended by addressing anemia, a common complication of chronic renal failure. Increased urine output (choice A) is not directly related to the action of epoetin alfa. Decreased blood pressure (choice B) is not a primary expected outcome of epoetin alfa therapy. Stable potassium levels (choice D) are important but not a direct indicator of the effectiveness of epoetin alfa in this context.

Correct Answer: C

Rationale: Clear lung sounds indicate that the antibiotics are effectively treating the bacterial pneumonia by resolving the infection and reducing the inflammation in the lungs, leading to improved air exchange and ventilation. Increased respiratory rate (Choice A) and decreased oxygen saturation (Choice B) are indicative of ongoing respiratory distress and ineffective treatment. Elevated white blood cell count (Choice D) suggests a persistent infection rather than effective treatment.

Correct Answer: B

Rationale: A serum potassium level of 2.8 mEq/L is critically low and can cause cardiac arrhythmias, requiring immediate intervention. Hypokalemia is a life-threatening condition that needs prompt correction to prevent serious complications. High serum glucose levels (choice A) are a concern in diabetes but do not pose an immediate life-threatening risk compared to severe hypokalemia. Serum sodium (choice C) and serum bicarbonate levels (choice D) are within normal ranges and do not require immediate intervention.
