HESI 799 RN Exit Exam Quizlet

Correct Answer: A

Rationale: Corrected Rationale: An electrocardiogram (ECG) should be performed first to assess for cardiac ischemia in a client with a history of myocardial infarction and chest pain. An ECG provides immediate information about the heart's electrical activity, helping to identify changes indicative of cardiac ischemia or infarction. Chest X-ray (Choice B) is not the initial diagnostic test for assessing chest pain related to myocardial infarction. Arterial blood gases (Choice C) are used to assess oxygenation and acid-base balance but are not the primary diagnostic test for myocardial infarction. An echocardiogram (Choice D) may provide valuable information about cardiac structure and function, but it is not the first-line diagnostic test for acute chest pain in a client with a history of myocardial infarction.

Correct Answer: A

Rationale: A serum ammonia level of 100 mcg/dl is most concerning in a client with hepatic encephalopathy. Elevated serum ammonia levels indicate significant liver dysfunction and an increased risk of worsening encephalopathy. Bilirubin level and prothrombin time are important in assessing liver function, but in the context of hepatic encephalopathy, elevated ammonia levels take precedence as they directly contribute to neurological symptoms. Serum sodium level, though important, is not the primary concern when managing hepatic encephalopathy.

Correct Answer: D

Rationale: The correct answer is D: Bronchoconstriction and airway inflammation. During an acute asthma episode, bronchoconstriction and airway inflammation occur, leading to difficulty breathing. Choices A, B, and C are incorrect. Inflammation of the mucous membrane and bronchospasm (Choice A) are part of the pathophysiology of asthma but do not fully explain the symptoms during an acute episode. Increased mucus production and airway obstruction (Choice B) are also seen in asthma but are not the primary cause of acute symptoms. Hyperinflation of the lungs and alveolar collapse (Choice C) are not typical features of an acute asthma episode.

Correct Answer: A

Rationale: In a scenario where a client with hyperthyroidism is not responding to medications, the nurse's priority action should be to notify the healthcare provider. This is important because the client may require immediate intervention, such as adjusting the treatment plan or exploring alternative therapies. Reviewing the client's medication history (choice B) may be relevant but not as urgent as involving the healthcare provider. While preparing the client for thyroid function tests (choice C) may be necessary as part of the evaluation process, it is not the most immediate action to take. Initiating seizure precautions (choice D) is not directly related to the non-responsiveness of medications in hyperthyroidism and is not a priority in this situation.

Correct Answer: A

Rationale: After observing ecchymosis at the fracture site, indicating hematoma formation, the nurse's priority is to document the extent of the bruising in the medical record. This documentation helps track the client's condition, aids in treatment planning, and serves as a baseline for monitoring changes. Applying a cold compress (choice B) may be contraindicated due to the risk of vasoconstriction and potential tissue damage. Elevating the affected limb (choice C) can be beneficial for reducing swelling in some cases, but documenting the bruising is the immediate concern. Notifying the healthcare provider (choice D) is not necessary at this stage unless there are other concerning symptoms or complications beyond the hematoma formation.
