HESI RN Exit Exam 2024 Quizlet

Correct Answer: A

Rationale: In a client with chronic kidney disease (CKD) receiving erythropoietin therapy, the nurse should closely monitor the serum potassium level. Erythropoietin therapy can increase red blood cell production, leading to a higher demand for potassium. Monitoring potassium levels is crucial to prevent hyperkalemia, a potential risk associated with this therapy. Hemoglobin level (Choice B) is important to assess the effectiveness of erythropoietin therapy, but monitoring potassium levels takes precedence due to the risk of hyperkalemia. White blood cell count (Choice C) and serum calcium level (Choice D) are not directly affected by erythropoietin therapy in the context of chronic kidney disease.

Correct Answer: D

Rationale: A platelet count of 90,000/mm3 is low and concerning for a client scheduled for a renal biopsy, as it increases the risk of bleeding. Thrombocytopenia, indicated by a low platelet count, can lead to impaired blood clotting, posing a significant risk of bleeding during or after the biopsy procedure. Elevated serum creatinine levels may be expected in chronic kidney disease but are not directly related to bleeding risk during a renal biopsy. Prothrombin time and hemoglobin levels are not as directly relevant to the bleeding risk associated with a renal biopsy as platelet count.

Correct Answer: C

Rationale: An oxygen saturation of 85% is significantly low for a client with COPD and indicates hypoxemia, requiring immediate intervention. In COPD, the body's ability to oxygenate adequately is already compromised, so a saturation of 85% is particularly concerning. A barrel-shaped chest and use of accessory muscles are common findings in COPD due to chronic air trapping and increased work of breathing. While a respiratory rate of 28 breaths per minute is elevated, a low oxygen saturation is a more critical finding that necessitates prompt attention.

Correct Answer: D

Rationale: The correct action for the nurse to implement after a client with hepatic encephalopathy has loose stools following lactulose administration is to monitor the client's mental status. Lactulose is given to lower serum ammonia levels in hepatic encephalopathy, and loose stools can be an expected side effect of its use. Monitoring mental status is crucial because changes in mental status, such as confusion or altered level of consciousness, are key indicators of hepatic encephalopathy worsening. Sending a stool specimen to the lab would not be the priority in this situation as loose stools are a known effect of lactulose. Measuring abdominal girth is more relevant for conditions like ascites, not loose stools. Encouraging increased fiber in the diet may be beneficial for constipation but is not the immediate action needed when loose stools occur after lactulose administration.

Correct Answer: C

Rationale: The correct needle to use for administering intravenous fluids via an implanted port is a non-coring (Huber) needle. This type of needle is specifically designed to access implanted ports without coring the septum, which helps prevent damage. Choice A, the one with the clamp and no needle, is incorrect as it does not describe a needle suitable for accessing an implanted port. Choice B, a butterfly needle, is not typically used for accessing implanted ports. Choice D, a standard hypodermic needle, is not ideal for accessing ports as it can damage the septum.
