HESI Fundamentals Questions
Question 1 of 5
The nurse explains to an older adult male the procedure for collecting a 24-hour urine specimen for creatinine clearance. Which action is most important for the nurse to include in their care plan for the shift?
Correct Answer: C
Rationale: To ensure accurate creatinine clearance results, it is crucial to collect all urine within the 24-hour period. The process should begin with discarding the first specimen and then collecting all subsequent urine in the designated 24-hour collection container. This ensures that the sample is complete and accurate for the creatinine clearance calculation.
Question 2 of 5
When assessing a male client, the nurse finds that he is fatigued and experiencing muscle weakness, leg cramps, and cardiac dysrhythmias. Based on these findings, the nurse plans to check the client's laboratory values to validate the existence of which condition?
Correct Answer: D
Rationale: The symptoms of fatigue, muscle weakness, leg cramps, and cardiac dysrhythmias are classic manifestations of hypokalemia. Potassium plays a vital role in muscle function and cardiac conduction, so a deficiency can lead to these symptoms. Checking the client's laboratory values for potassium levels will help confirm the presence of hypokalemia.
Question 3 of 5
While changing a client's post-operative dressing, the nurse observes a red and swollen wound with a moderate amount of yellow and green drainage and a foul odor. Given a positive MRSA result, what is the most important action for the nurse to take?
Correct Answer: C
Rationale: Initiating contact precautions is crucial in this situation to prevent the spread of MRSA infection. MRSA is a highly contagious bacterium that can spread through direct contact with an infected wound or by touching contaminated surfaces. By implementing contact precautions, the nurse can help contain the infection and protect other patients, healthcare workers, and visitors from being exposed to MRSA.
Question 4 of 5
While interviewing a client, the nurse records the assessment in the electronic health record. Which statement is most accurate regarding electronic documentation during an interview?
Correct Answer: C
Rationale: Choosing electronic documentation during an interview may hinder the nurse's ability to observe the client's nonverbal cues. Nonverbal communication, such as body language and facial expressions, plays a crucial role in understanding a client's feelings and needs. Focusing on entering data electronically may lead to missing important nonverbal cues that could provide valuable insights into the client's condition or emotions.
Question 5 of 5
The healthcare professional retrieves hydromorphone 4mg/mL from the Pyxis MedStation, an automated dispensing system, for a client who is receiving hydromorphone 3 mg IM 6 hours PRN for severe pain. How many mL should the healthcare professional administer to the client? (Enter the numerical value only. If rounding is required, round to the nearest tenth)
Correct Answer: A
Rationale: In this scenario, the correct answer is A) 0.8 mL. To calculate the amount to administer, you need to use the formula: Desired dose / Available dose = Volume to administer. The client requires 3 mg of hydromorphone, and the concentration available is 4 mg/mL. By dividing 3 mg by 4 mg/mL, you get 0.75 mL. However, since rounding to the nearest tenth is required, you round 0.75 mL to 0.8 mL, making option A the correct answer. Option B (0.75 mL) is close but not rounded to the nearest tenth as required. Option C (0.7 mL) and Option D (0.9 mL) are further from the correct calculated value. Educationally, understanding how to calculate medication dosages accurately is crucial for nurses to prevent medication errors and ensure patient safety. Nurses must have a strong foundation in medication calculations to deliver optimal care. Practicing these calculations through scenarios like this one helps reinforce this essential skill.
