Evolve HESI Medical Surgical Practice Exam Quizlet

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: Corrected Choice A: Right lower quadrant pain is a classic and key symptom of appendicitis. Pain in the right lower quadrant is typically the initial symptom and is a result of inflammation and irritation of the appendix. This pain can start around the umbilicus and then migrate to the right lower quadrant. It is important to note that appendicitis rarely presents with pain in the left lower quadrant or generalized abdominal pain. Rebound tenderness, indicated in Choice D, is a sign of peritoneal irritation and is associated with appendicitis, but it is not as characteristic as the right lower quadrant pain in the initial presentation of appendicitis.

Correct Answer: A

Rationale: Hypertension is the correct answer. Hypertension, also known as high blood pressure, is a major risk factor for stroke because it puts increased pressure on blood vessels in the brain, making them more prone to damage and increasing the likelihood of a stroke. While diabetes, obesity, and smoking are also risk factors for stroke, hypertension is the most commonly associated condition with a high risk of stroke due to its direct impact on the blood vessels.

Correct Answer: A

Rationale: Smoking is the correct answer as it is a well-established common cause of chronic obstructive pulmonary disease (COPD). Smoking leads to long-term damage to the lungs, contributing to the development of COPD. Choice B, asthma, is not a cause but a separate respiratory condition characterized by airway inflammation and hyperresponsiveness. Allergies, choice C, are not a direct cause of COPD but can exacerbate symptoms in individuals with existing COPD. Chronic bronchitis, choice D, is a type of COPD, not a cause of COPD itself, making it an incorrect choice in this context.

Correct Answer: A

Rationale: Assisting the client to an upright position is the most appropriate intervention in this scenario. An upright position helps optimize lung expansion and aids in improving ventilation, which can alleviate shortness of breath. This position also assists in reducing anxiety by providing a sense of control and comfort. Administering a sedative (Choice B) may further depress the respiratory drive in a client with COPD and should be avoided unless absolutely necessary. Applying a high-flow Venturi mask (Choice C) may be indicated later based on oxygenation needs, but the immediate focus should be on positioning. Encouraging the client to drink water (Choice D) may not directly address the respiratory distress and anxiety experienced by the client.
