HESI Medical Surgical Exam

Correct Answer: C

Rationale: Encouraging the client's use of picture charts is the most appropriate intervention for a client with expressive aphasia. Picture charts provide visual cues that can aid in communication and reduce frustration for the client. This intervention can help the client express their needs and thoughts effectively. Teaching sign language (Choice A) may be challenging and not as practical in this situation as it may not address the specific communication barriers caused by expressive aphasia. Speaking slowly (Choice B) may not fully address the communication difficulties associated with expressive aphasia. Asking simple questions (Choice D) may not be effective as the client may have difficulty understanding and responding due to the nature of expressive aphasia.

Correct Answer: B

Rationale: In a patient presenting with severe chest pain radiating to the left arm, the priority diagnostic test is an Electrocardiogram (ECG) to assess for myocardial infarction. An ECG can quickly identify changes indicative of ischemia or infarction, guiding prompt management. A Complete Blood Count (CBC) may provide some information but is not the primary test for evaluating chest pain related to myocardial infarction. A Chest X-ray can be useful in assessing lung pathologies or certain cardiac conditions; however, it does not provide immediate information on myocardial infarction, making it a secondary option in this scenario. Serum electrolytes may become important in later stages but do not offer immediate insights into myocardial infarction. Therefore, they are a lower priority compared to obtaining an ECG for timely diagnosis and intervention.

Correct Answer: D

Rationale: The correct answer is D: Stroke. Hypertension can lead to stroke due to the increased pressure on blood vessels in the brain, which can result in reduced blood flow and oxygen to the brain tissue. While choices B (Heart failure) and C (Kidney failure) can be complications of hypertension, they are not as directly associated as stroke. Choice A, Diabetes, is not a direct complication of hypertension but rather a separate condition that can be influenced by various factors. However, stroke is more commonly linked to the increased pressure on blood vessels in the brain in individuals with hypertension.

Correct Answer: A

Rationale: A serum sodium level of 185 mEq/L (185 mmol/L) is dangerously high and indicates severe dehydration, requiring immediate intervention to prevent neurological damage. The other options are not as critical as high serum sodium levels, which can lead to serious complications such as seizures, coma, and death if not promptly addressed. Dry skin with poor skin turgor and polyuria with excessive thirst are common findings in clients with Diabetes Insipidus and should be managed but do not pose an immediate threat to the client's life. An apical heart rate of 110 beats per minute may indicate tachycardia, which could be related to dehydration but is not as urgent as addressing the severe hypernatremia.

Correct Answer: D

Rationale: The primary purpose of administering IV fluids to a patient in septic shock is to maintain adequate tissue perfusion. In septic shock, there is a significant drop in blood pressure and systemic vascular resistance leading to poor tissue perfusion. IV fluids help to restore intravascular volume, improve perfusion to vital organs, and prevent organ failure. Choice A ('To reduce blood pressure') is incorrect because IV fluids in septic shock aim to restore tissue perfusion rather than lower blood pressure. Choice B ('To increase cardiac output') is incorrect as the primary goal is to improve tissue perfusion, not specifically increase cardiac output. Choice C ('To stabilize blood glucose levels') is unrelated to the primary purpose of administering IV fluids in septic shock, which is to address the compromised tissue perfusion.
