ATI PN Adult Medical Surgical 2019

Correct Answer: B

Rationale: Corrected Rationale: When caring for a patient on warfarin, monitoring prothrombin time (PT) is crucial. PT helps assess the blood's ability to clot properly, ensuring the patient maintains therapeutic anticoagulation levels while minimizing bleeding risks. Platelet count (Choice A) is important but not the most critical for warfarin therapy. Hemoglobin level (Choice C) and white blood cell count (Choice D) are not directly related to monitoring the effects of warfarin.

Correct Answer: B

Rationale: The correct answer is B: Lowered cholesterol levels. Atorvastatin is a medication commonly prescribed to lower cholesterol levels, which is crucial in reducing the risk of further cardiovascular events, including myocardial infarction (MI). Monitoring cholesterol levels is essential to assess the effectiveness of atorvastatin therapy and its role in preventing future cardiac complications. Choices A, C, and D are incorrect because increased blood pressure, decreased heart rate, and improved liver function are not direct indicators of atorvastatin's effectiveness in a client with a history of MI.

Correct Answer: C

Rationale: The correct instruction for a client prescribed salmeterol (Serevent) is to use it twice daily for long-term control. Salmeterol is a long-acting bronchodilator that is not intended for acute asthma attacks or as-needed use for wheezing. Choice A is incorrect because salmeterol is not used for acute asthma attacks. Choice B is incorrect as salmeterol is not meant to replace the albuterol inhaler but rather used for long-term control. Choice D is incorrect because salmeterol should not be used as needed; it is a maintenance medication for asthma.

Correct Answer: D

Rationale: Decreased vital capacity is the most critical assessment finding in a client with Guillain-Barr� syndrome as it indicates respiratory compromise. This requires immediate intervention to ensure adequate ventilation and prevent respiratory failure, a common complication of this syndrome. Monitoring and maintaining respiratory function are vital in these clients to prevent complications such as respiratory distress, hypoxia, and respiratory failure. Loss of deep tendon reflexes and ascending weakness are typical manifestations of Guillain-Barr� syndrome but do not require immediate action compared to compromised respiratory function. New onset of confusion may be a concern but is not as immediately life-threatening as decreased vital capacity.

Correct Answer: A

Rationale: The correct first action for a client presenting with confusion, sweating, and palpitations, suggestive of hypoglycemia, is to check the client's blood glucose level. This step helps to confirm if the symptoms are due to low blood sugar levels and guides appropriate interventions. Administering insulin without knowing the current blood glucose level can be dangerous and is not recommended as the initial step. Offering a high-protein snack may be necessary after confirming hypoglycemia, but checking the blood glucose level takes precedence. Measuring blood pressure is not the priority in this situation; addressing hypoglycemia is the immediate concern.
