HESI RN Exit Exam 2024 Quizlet

Correct Answer: D

Rationale: A serum bicarbonate level of 18 mEq/L is most concerning in a client with DKA as it indicates metabolic acidosis, requiring immediate intervention. In DKA, the body produces excess ketones, leading to metabolic acidosis. A low serum bicarbonate level is a key indicator of this acid-base imbalance. Elevated serum glucose levels are expected in DKA but are managed through insulin therapy. Serum potassium levels can fluctuate in DKA due to insulin deficiency, but a value of 5.5 mEq/L is not as immediately concerning as metabolic acidosis. Therefore, the most critical finding in this scenario is the low serum bicarbonate level.

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.

Correct Answer: A

Rationale: The correct answer is A, Magnesium hydroxide (Maalox). In clients with chronic kidney disease (CKD), magnesium can accumulate to toxic levels as the kidneys are unable to excrete it efficiently. This can lead to hypermagnesemia, causing serious and potentially life-threatening complications. Birth control pills (choice B) are metabolized mainly by the liver and do not pose a significant threat to clients with CKD. Cough syrup containing codeine (choice C) should be used cautiously in CKD due to the risk of respiratory depression but does not pose as great a threat as magnesium accumulation. Cold medication containing alcohol (choice D) should be avoided in CKD but does not present the same level of danger as magnesium toxicity.

Therefore, the most critical finding in this scenario is the low serum bicarbonate level.

Correct Answer: A

Rationale: The correct answer is A, 'Increased fatigue.' In a client with CKD receiving erythropoietin therapy, increased fatigue can be a sign of polycythemia, a condition characterized by an elevated red blood cell count. This can lead to increased blood viscosity and raise the risk of thromboembolic events, necessitating immediate intervention. Elevated blood pressure (choice B) is a common concern in CKD but does not require immediate intervention in this context. Headache (choice C) may be related to elevated blood pressure but is not the most critical finding requiring immediate attention. Elevated hemoglobin (choice D) is an expected outcome of erythropoietin therapy and does not require immediate intervention unless excessively high.
