HESI RN CAT Exit Exam 1

Correct Answer: C

Rationale: The correct answer is C: Rationalization. Rationalization is a defense mechanism where the client justifies their stress and need for perfection by creating logical explanations or excuses. In this case, the client is rationalizing their stress by believing that everything in their life must be perfect. Repression (choice A) involves unconsciously blocking out thoughts or feelings. Sublimation (choice B) is redirecting unacceptable impulses into socially acceptable activities. Displacement (choice D) involves transferring emotions from one target to another.

Correct Answer: C

Rationale: The correct answer is C because a fast heart rate and jitteriness are common side effects of bronchodilators like albuterol. Choice A is incorrect as nervousness is more likely a side effect of the medication than solely related to hypoxia. Choice B is incorrect as it provides a partial explanation focusing only on tremors and heart rate, not mentioning jitteriness. Choice D is incorrect because excessive coughing and tachypnea are not typically associated with bronchodilator use; instead, they may indicate inadequate relief or other issues.

Correct Answer: B

Rationale: The correct answer is B. A diet high in protein and carbohydrates is not specifically required for Addison's disease. The focus should be on maintaining a balanced diet that is rich in fruits, vegetables, whole grains, and adequate protein sources. Choice A is correct as adherence to medication therapy is crucial in managing Addison's disease. Choice C is correct as caffeine can exacerbate symptoms of Addison's disease. Choice D is correct as dizziness can be a sign of adrenal crisis in Addison's disease, and prompt notification of healthcare providers is essential.

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: To calculate the infusion rate, we first need to determine the frequency of contractions per hour. If contractions are occurring every 2 to 3 minutes, this corresponds to 20 to 30 contractions in an hour (60 minutes). The average is 25 contractions in an hour. The pump should be infusing 1 ml for each contraction, so the infusion rate should be 25 ml/hr. Therefore, the correct answer is 42 ml/hr. Choices B, C, and D are incorrect as they do not align with the calculation based on the given data.
