HESI RN CAT Exit Exam 1

Correct Answer: A

Rationale: The correct answer is A: Tachycardia, mental status change, and low urine output are early signs of shock. Tachycardia is the body's compensatory mechanism to maintain perfusion, mental status changes can indicate decreased cerebral perfusion, and low urine output reflects poor renal perfusion. Choices B, C, and D are incorrect. Warm skin, hypertension, and constricted pupils are not typical findings in the early stages of shock. Bradycardia, hypotension, and respiratory acidosis are more indicative of late-stage shock. Mottled skin, tachypnea, and hyperactive bowel sounds can be seen in various conditions but are not specific early signs of shock.

Correct Answer: B

Rationale: In this situation, the nurse should prioritize the safety of the client. Taking the client to a room for supervision by staff is crucial to ensure immediate safety and further assessment of the client's condition. While cleaning and assessing the client's wrists are important, ensuring ongoing safety and monitoring by staff is the priority. Calling the healthcare provider at this moment may cause delays in providing immediate assistance. Finding supplies to put a dressing on the client's wrists can wait until the client is in a safe environment. Therefore, option B is the best course of action to address the client's safety needs promptly.

Correct Answer: C

Rationale: Increased blood pressure is the desired effect of administering dopamine (Intropin) to treat hypotension. Dopamine acts by stimulating adrenergic receptors, leading to vasoconstriction and increased cardiac output. This results in an elevation of blood pressure. Choices A, B, and D are incorrect as they do not directly reflect the therapeutic action of dopamine in treating hypotension. Increased heart rate may indicate the body compensating for low blood pressure, increased urinary output is more related to kidney function, and increased respiratory rate is often seen in response to respiratory issues, not the action of dopamine on hypotension.

Correct Answer: A

Rationale: Choice A is the best response because it educates the client about the role of heparin in preventing future clot formation rather than dissolving the existing clot. This helps the client understand the medication's function and the importance of closely monitoring for signs of bleeding, a common side effect of heparin therapy. Choice B acknowledges the client's concern but does not provide accurate information about heparin's mechanism of action. Choice C is premature as it suggests transitioning to home therapy without addressing the client's concerns or explaining heparin's purpose. Choice D does not address the client's statement and instead questions their desire to leave the hospital.

Correct Answer: C

Rationale: The correct answer is C. Clients in renal failure are at high risk for hypomagnesemia due to their impaired kidney function. Renal failure can lead to decreased excretion of magnesium, resulting in its buildup in the body and potential hypomagnesemia. This client requires careful nursing assessment for signs and symptoms of hypomagnesemia to prevent complications. Choices A, B, and D are not as directly associated with renal failure and its impact on magnesium levels. Intractable vomiting, hyperparathyroidism, and excessive consumption of simple carbohydrates may have other health implications but are not as strongly linked to hypomagnesemia as renal failure.
