Evolve HESI Medical Surgical Practice Exam Quizlet

Correct Answer: B

Rationale: The primary goal of treating pneumonia is to eliminate the infection. Antibiotics are commonly used to target the specific pathogen causing pneumonia. While reducing inflammation and preventing complications are important aspects of treatment, the key focus initially is on eradicating the infectious agent to improve the patient's condition and prevent further spread of the infection.

Correct Answer: A

Rationale: The correct answer is A: Decreased blood flow. In clients with peripheral vascular disease (PVD) and a history of heart failure, decreased blood flow due to heart failure can result in reduced oxygen delivery to tissues. This reduced oxygen supply can lead to low exercise tolerance. Increased blood flow (Choice B) is not typically associated with reduced exercise tolerance in these clients. Decreased pain (Choice C) and increased blood viscosity (Choice D) are not the primary factors contributing to low exercise tolerance in this scenario.

Correct Answer: B

Rationale: Obtaining a urethral drainage specimen for culture is crucial in diagnosing a potential sexually transmitted infection (STI) in this client. While assessing for perineal symptoms like itching, erythema, and excoriation (Choice C) may provide additional information, obtaining a culture is more definitive. Observing for a chancroid-like lesion (Choice A) is not as pertinent as obtaining a culture for a broader diagnostic approach. Identifying all sexual partners in the last four days (Choice D) is important for contact tracing but obtaining a specimen for culture takes priority in this scenario.

Correct Answer: D

Rationale: In a patient with cirrhosis, a low platelet count is the most concerning lab result. Thrombocytopenia, or low platelet count, is common in cirrhosis due to impaired platelet production in the liver. It significantly increases the risk of bleeding and can lead to serious complications such as hemorrhage. Elevated liver enzymes (Choice A) are expected in cirrhosis but may not directly indicate the severity of the disease. Low albumin levels (Choice B) are common in cirrhosis and can contribute to fluid retention but do not pose an immediate risk of bleeding. Elevated bilirubin levels (Choice C) are also expected in cirrhosis and typically indicate impaired liver function but do not directly increase the risk of bleeding as much as a low platelet count.

Correct Answer: B

Rationale: Administering oxygen is a priority intervention in heart failure because it helps improve oxygenation, alleviate hypoxemia, and reduce the workload on the heart. Oxygen therapy is crucial in managing acute heart failure exacerbations. While diuretics (Choice A) are commonly used in heart failure to reduce fluid overload, administering oxygen takes precedence due to its immediate impact on oxygen delivery. Beta-blockers (Choice C) and vasodilators (Choice D) are also important in heart failure management, but in the acute setting, ensuring adequate oxygen supply is the priority.
