HESI RN Exit Exam 2024 Quizlet Capstone

Correct Answer: A

Rationale: The correct answer is A: Start an IV infusion of normal saline. The client is showing signs of dehydration, such as abdominal cramping, vomiting, lethargy, and confusion, which can be exacerbated by hyperglycemia. Rehydration is the initial priority to address the fluid imbalance. Option B, obtaining a serum potassium level, though important in the management of diabetes, is not the immediate priority over rehydration. Option C, administering the client's usual dose of insulin, should only be done after addressing the dehydration and confirming the client's blood glucose levels. Option D, assessing the pupillary response to light, is not the most urgent intervention needed in this situation compared to rehydration to correct fluid imbalance.

Correct Answer: C

Rationale: When a pediatric client is taking propranolol, the nurse should instruct the parents to report signs of overdose, including bradycardia. Propranolol is a beta-blocker that can lead to dangerously slow heart rate as a sign of overdose. While increased respiratory rate, seizures, and irritability may occur in some cases, bradycardia is the most critical symptom indicating an overdose of this medication.

Correct Answer: B

Rationale: The correct answer is B: Partial thromboplastin time (PTT). PTT is the lab value used to monitor the effectiveness of heparin therapy in clients with DVT. It measures the intrinsic pathway of coagulation and is prolonged by heparin therapy. Prothrombin time (PT) and International Normalized Ratio (INR) are primarily used to monitor warfarin therapy, not heparin. Checking hemoglobin and hematocrit levels is important but does not directly assess the effectiveness of heparin therapy in DVT.

Correct Answer: B

Rationale: The CAGE questionnaire is a widely used screening tool for alcohol dependence. Two or more positive responses suggest a higher likelihood of alcohol dependence. One positive response may indicate potential alcohol issues, but two or more significantly increase the likelihood of dependence. Therefore, choice B is the most appropriate interpretation. Choice A is incorrect because the CAGE questionnaire specifically focuses on alcohol-related issues, not substance abuse in general. Choice C is incorrect as one positive response does not indicate addiction but rather raises a concern. Choice D is incorrect as not all responses need to be positive to suggest alcohol dependence.

Correct Answer: A

Rationale: A mucopurulent cough and night sweats are hallmark signs of active tuberculosis. These symptoms are key indicators of TB as the combination of a productive cough with night sweats is highly suggestive of the disease. Fatigue and headache (choice B) are nonspecific symptoms that can occur in many conditions and are not specific to TB. Persistent cough and weight gain (choice C) are not typical findings in tuberculosis. Weight loss and fever (choice D) can be present in TB, but the specific combination of mucopurulent cough and night sweats is more specific to the diagnosis.
