HESI RN Exit Exam 2024 Quizlet

Correct Answer: A

Rationale: A serum potassium level of 5.5 mEq/L is concerning in a client with ESRD scheduled for hemodialysis as it indicates hyperkalemia, requiring immediate intervention. Hyperkalemia can lead to serious cardiac arrhythmias, especially during hemodialysis. Serum calcium, serum creatinine, and white blood cell count, while important, do not pose immediate life-threatening risks like hyperkalemia.

Correct Answer: C

Rationale: The correct answer is C: Use of accessory muscles. In a client with COPD and pneumonia, the use of accessory muscles indicates increased work of breathing and may signal respiratory failure. Immediate intervention is necessary to prevent further deterioration of the respiratory status. Choice A, an oxygen saturation of 90%, though low, may not require immediate intervention as it is above the typical threshold for initiating supplemental oxygen. Choice B, a respiratory rate of 24 breaths per minute, falls within the normal range for an adult and may not be an immediate cause for concern. Choice D, inspiratory crackles, are indicative of fluid in the lungs but may not require immediate intervention unless accompanied by other concerning signs like decreased oxygen saturation or increased respiratory distress.

Correct Answer: C

Rationale: The correct response when a terminally ill child asks about what will happen to their body when they die is to provide a truthful and straightforward answer. Choice C, 'The heart will stop beating and you will stop breathing,' is the best response because it offers a simple and honest explanation without delving into spiritual or emotional aspects that may be confusing or distressing to the child. Choices A and D deflect the question and do not address the child's inquiry directly. Choice B, 'Why do you want to know about what will happen to your body when you die?' may come across as dismissive or evasive, rather than providing the clear information the child is seeking.

Correct Answer: C

Rationale: The correct answer is C, International Normalized Ratio (INR). The INR should be closely monitored in a client receiving warfarin (Coumadin) to assess the effectiveness and safety of anticoagulation therapy. Monitoring the INR helps ensure that the client is within the therapeutic range for anticoagulation to prevent complications such as bleeding or clotting. Choices A, B, and D are incorrect. While monitoring electrolyte levels like serum potassium and sodium is important in overall client care, they are not specific to monitoring the effects of warfarin therapy. Prothrombin time (PT) is a component of INR and helps in monitoring warfarin therapy, but INR gives a standardized result that is independent of the laboratory method used, making it the preferred choice for monitoring warfarin therapy.

Correct Answer: D

Rationale: The correct answer is D. The statement 'I should reduce my fluid intake to control my blood pressure' indicates a misunderstanding. It is important to note that fluid restriction is not typically necessary when taking calcium channel blockers. Choices A, B, and C demonstrate good understanding of medication adherence, dietary precautions, and nutrition recommendations when taking a calcium channel blocker, making them incorrect choices for further teaching.
