Evolve HESI Medical Surgical Practice Exam Quizlet

Correct Answer: A

Rationale: The correct answer is A. Learning is best demonstrated by a change in behavior. A client who can safely and correctly perform the procedure shows they have acquired the skill. Choice B is incorrect because critiquing the nurse's performance does not directly demonstrate the client's ability to perform the procedure. Choice C is incorrect because explaining the steps does not guarantee the client can physically perform the injection. Choice D is incorrect as answering a posttest only assesses theoretical knowledge, not practical application.

Correct Answer: A

Rationale: The correct answer is administering bronchodilators. During an acute asthma attack, the primary goal is to relieve airway constriction and bronchospasm to improve breathing. Bronchodilators, such as short-acting beta-agonists, are the cornerstone of treatment as they help dilate the airways quickly. Administering antibiotics (choice B) is not indicated unless there is an underlying bacterial infection. Administering IV fluids (choice C) may be necessary in some cases, but it is not the primary intervention for an acute asthma attack. Administering corticosteroids (choice D) is often used as an adjunct therapy to reduce airway inflammation, but it is not the primary intervention during the acute phase of an asthma attack.

Correct Answer: A

Rationale: Administering oxygen is the priority intervention for a patient with a suspected myocardial infarction to improve oxygenation. Oxygen helps ensure an adequate oxygen supply to the heart muscle, reducing the workload on the heart. Nitroglycerin and aspirin are important interventions in the treatment of MI; however, oxygen administration takes precedence to ensure adequate oxygenation. Morphine may be considered for pain relief, but it is not the initial priority in the treatment of a suspected MI.

Correct Answer: C

Rationale: The correct answer is C: Left end-diastolic pressure. Wedging the pulmonary artery catheter allows the nurse to obtain the pulmonary artery wedge pressure, which reflects the left end-diastolic pressure. This pressure is essential in assessing left ventricular function and diagnosing conditions like heart failure. Choices A, B, and D are incorrect because wedging the catheter does not directly provide information about cardiac output, right atrial blood flow, or cardiac index.

Correct Answer: A

Rationale: In a patient with liver cirrhosis, increased bilirubin levels would be expected. Liver cirrhosis leads to impaired liver function, causing a decrease in the liver's ability to process bilirubin, leading to its accumulation in the blood. This results in elevated bilirubin levels. Decreased albumin levels (choice B) may occur in liver cirrhosis due to impaired liver synthesis of proteins, but it is not as specific as increased bilirubin levels. Increased liver enzymes (choice C) can be seen in liver damage but are not as characteristic as elevated bilirubin levels. Decreased platelet count (choice D) can occur in liver cirrhosis due to hypersplenism, but it is not as specific as increased bilirubin levels in this context.
