HESI 799 RN Exit Exam

Correct Answer: B

Rationale: A serum potassium level of 5.5 mEq/L is concerning in a client with ESRD scheduled for hemodialysis as it indicates hyperkalemia, which can lead to serious cardiac complications. Hyperkalemia can be exacerbated during hemodialysis, making it crucial to closely monitor serum potassium levels before the procedure. Monitoring serum creatinine, serum calcium, or hemoglobin levels is important in managing ESRD but is not the immediate focus before hemodialysis. Therefore, option B is the correct choice.

Correct Answer: A

Rationale: The correct action for the nurse to implement is to digitally check the client for a fecal impaction. In this scenario, the client's presentation of frequent small amounts of liquid stool after a period of no bowel movement suggests a possible impaction. By performing a digital examination, the nurse can assess for the presence of a blockage that may be causing the symptoms. Administering a laxative (Choice B) without assessing for impaction can worsen the situation. Increasing fluid intake (Choice C) is generally beneficial for bowel health but may not address the immediate issue of a potential impaction. Performing a digital rectal examination (Choice D) is similar to Choice A but is more focused on assessing the rectum itself rather than checking for an impaction.

Correct Answer: D

Rationale: The correct answer is D. Limiting caffeine intake is a positive lifestyle modification for managing hypertension. The statement indicates that the client understands the importance of reducing caffeine intake. Choices A, B, and C all reflect appropriate lifestyle modifications for managing hypertension, indicating good understanding by the client.

Correct Answer: A

Rationale: The correct answer is A: International Normalized Ratio (INR). The INR should be closely monitored in a client with atrial fibrillation to assess the effectiveness and safety of anticoagulation therapy with warfarin. Monitoring the INR helps to ensure that the client is within the therapeutic range to prevent complications such as thrombosis or bleeding. Choices B, C, and D are less relevant in this scenario. While serum glucose levels are important in assessing metabolic status, and white blood cell count and prothrombin time are important indicators for other conditions, they are not the primary focus when a client with atrial fibrillation presents with confusion.

Correct Answer: B

Rationale: Obtaining a wound swab for culture and sensitivity is the most important intervention in this situation. It helps identify the presence of infection in the postoperative wound that could be causing the elevated temperature. By obtaining a wound swab, healthcare providers can determine the appropriate treatment needed to address any infection. Initiating contact isolation (Choice A) may be necessary in certain situations but is not the priority in this case. Assessing temperature (Choice C) is important but does not directly address the underlying cause of the elevated temperature. Using alcohol-based solutions for hand hygiene (Choice D) is a standard practice for infection control but is not the most crucial intervention in this scenario.
