HESI Medical Surgical Practice Exam

Correct Answer: A

Rationale: Helicobacter pylori infection is the most common cause of peptic ulcers. This bacterium can weaken the protective mucous coating of the stomach and duodenum, allowing acid to get through to the sensitive lining beneath. NSAID use (Choice B) can also cause peptic ulcers by disrupting the stomach's mucosal barrier. Excessive alcohol consumption (Choice C) and stress (Choice D) can exacerbate and contribute to ulcer formation but are not the primary cause.

Correct Answer: B

Rationale: The best initial action by the nurse when a client expresses plans to use an inhaler for asthma symptoms but continue smoking cigarettes is to address denial. By explaining that denial of illness can interfere with the treatment regimen, the nurse educates the client about the impact of smoking on asthma treatment. This approach helps the client understand the importance of smoking cessation in managing asthma symptoms. Informing the healthcare provider (Choice A) may be necessary but is not the initial action in this scenario. Revising the plan of care (Choice C) should be considered after addressing the client's denial and educating them. Reviewing factors surrounding the client's beliefs about smoking cessation (Choice D) is relevant but not the best initial action when denial is identified.

Correct Answer: D

Rationale: The correct answer is to prepare the client for emergency surgery. The client's presentation with bright red blood in vomitus suggests active bleeding, which is a medical emergency. With a hemoglobin of 12 g/dL and a hematocrit of 35%, the client is likely experiencing significant blood loss that may require surgical intervention to address the source of bleeding. Continuing to monitor for blood loss (Choice A) is not appropriate in this acute situation where immediate action is necessary. Administering normal saline (Choice B) may help with fluid resuscitation but does not address the underlying cause of bleeding. Transfusing platelets (Choice C) is not indicated in this scenario as platelets are involved in clot formation and are not the primary treatment for active bleeding in this context.

Correct Answer: D

Rationale: An Ankle-Brachial Index of 0.65 suggests moderate arterial vascular disease in a client experiencing intermittent claudication, indicating compromised blood flow to the lower extremities during exercise. This finding requires further evaluation to assess the severity of arterial insufficiency and determine appropriate interventions. Choice A (Heart rate of 57 bpm) is within the normal range for an adult at rest and indicates good cardiovascular fitness. Choice B (SpO2 of 94% on room air) is slightly lower than the normal range but is generally acceptable in a healthy individual. Choice C (Blood pressure of 134/82) falls within the normal range and does not raise immediate concerns in this context.

Correct Answer: C

Rationale: The correct answer is C. Cilostazol improves blood flow to the muscles, which helps alleviate symptoms of intermittent claudication. An improvement in walking distance without leg pain indicates the effectiveness of the medication. Choices A and B are not directly related to the expected outcome of Cilostazol therapy for intermittent claudication. Choice D is concerning for a potential adverse effect and should be reported to the healthcare provider immediately.
