HESI LPN
Fundamentals of Nursing HESI
1. A client has acute renal failure. Which of the following assessments provides the most accurate measure of the client's fluid status?
- A. Daily weight
- B. Intake and output
- C. Urine specific gravity
- D. Peripheral edema
Correct answer: A
Rationale: Daily weight is the most accurate measure of fluid status in a client with acute renal failure. Fluctuations in weight reflect changes in body fluid volume, including both fluid retention or loss. Intake and output, while important, may not always accurately reflect overall fluid status as it does not account for insensible losses. Urine specific gravity can provide information on urine concentration but does not offer a comprehensive assessment of overall fluid status. Peripheral edema, although a sign of fluid retention, is a more subjective assessment and may not always accurately reflect the client's fluid status like daily weight monitoring does.
2. A client is being treated for diabetic ketoacidosis (DKA). Which laboratory value would be most concerning?
- A. Blood glucose of 350 mg/dL
- B. Serum bicarbonate of 18 mEq/L
- C. Arterial pH of 7.20
- D. Serum potassium of 5.5 mEq/L
Correct answer: C
Rationale: In a client with diabetic ketoacidosis (DKA), the most concerning laboratory value is an arterial pH of 7.20. An arterial pH of 7.20 indicates severe acidosis, which is a critical condition requiring immediate intervention. This pH level reflects a significant imbalance in the body's acid-base status, potentially leading to serious complications. High blood glucose levels (choice A) are expected in DKA but do not directly indicate the severity of acidosis. A serum bicarbonate level of 18 mEq/L (choice B) is low but not as immediately critical as a pH of 7.20. Serum potassium of 5.5 mEq/L (choice D) is elevated, which can occur in DKA due to insulin deficiency, but it is not the most concerning value in this scenario.
3. A client with a history of atrial fibrillation is taking digoxin (Lanoxin). Which finding should the healthcare provider be notified of immediately?
- A. Heart rate of 52 beats per minute
- B. Blood pressure of 110/70 mmHg
- C. Blood glucose level of 180 mg/dL
- D. Potassium level of 4.0 mEq/L
Correct answer: A
Rationale: A heart rate of 52 beats per minute is a critical finding in a client taking digoxin, as it may indicate digoxin toxicity. Digoxin can cause bradycardia as a side effect, and a heart rate of 52 bpm warrants immediate attention to prevent adverse outcomes. Monitoring and reporting changes in heart rate are crucial in clients on digoxin therapy to prevent serious complications. The other vital signs and laboratory values provided are within normal ranges or not directly associated with digoxin toxicity in this scenario, making them lower priority for immediate reporting.
4. What is the most effective method to prevent medication errors during administration?
- A. Relying on memory for medication dosages
- B. Using a bar-code medication administration system
- C. Administering medications as quickly as possible to avoid delays
- D. Allowing another individual to administer medications
Correct answer: B
Rationale: Using a bar-code medication administration system is the best method to prevent medication errors during administration. This system verifies medication details electronically, ensuring that the correct medication is given to the right patient. Relying on memory for medication dosages (choice A) is not recommended as it can lead to errors. Administering medications quickly (choice C) may increase the risk of mistakes due to haste. Allowing another individual (choice D) to administer medications does not address the root cause of preventing errors during administration.
5. A client is preparing to attend a Gamblers Anonymous meeting for the first time. The prototype used by this group is the 12-step program developed by Alcoholics Anonymous. Number in order of priority how the steps would be addressed.
- A. Admitting to oneself and to another human being the exact nature of one's wrongs
- B. Acknowledging that one is entirely ready to have his or her defects of character removed
- C. Admitting that oneself is powerless over gambling and that one's life has become unmanageable
- D. Making an effort to practice the 12-step principles in all affairs, and to carry out this message to other compulsive gamblers
Correct answer: D
Rationale: The correct order of addressing the 12-step program typically begins with admitting powerlessness over the addiction and recognizing the unmanageability of one's life (Choice C). Following this, individuals move towards acknowledging their wrongs and sharing them with others (Choice A), then being ready to work on changing their character defects (Choice B), and finally, integrating the 12-step principles into their daily lives and helping others (Choice D). Choices A, B, and C are important steps in the program but come after admitting powerlessness and unmanageability, which is why Choice D is the correct answer.
