HESI Fundamentals Practice Exam
1. Which serum laboratory value should the nurse monitor carefully for a client who has had an NG tube for suctioning for the past week?
- A. White blood cell count
- B. Albumin
- C. Calcium
- D. Sodium
Correct answer: D
Rationale: The nurse should carefully monitor serum sodium levels for a client with an NG tube on suction for an extended period due to potential fluid loss and the risk of developing hyponatremia, an electrolyte imbalance. Hyponatremia can occur as a result of continual suctioning leading to fluid loss, making it crucial to monitor sodium levels to prevent complications associated with low sodium levels. Monitoring white blood cell count, albumin, or calcium is not directly related to the impact of NG tube suction on fluid and electrolyte balance, so these values are not the priority in this scenario.
2. A client with a diagnosis of anemia is receiving epoetin alfa (Epogen). Which laboratory test should the nurse monitor to evaluate the effectiveness of this medication?
- A. White blood cell count.
- B. Hemoglobin and hematocrit.
- C. Platelet count.
- D. Blood urea nitrogen (BUN) and creatinine.
Correct answer: B
Rationale: To evaluate the effectiveness of epoetin alfa (Epogen) in treating anemia, the nurse should monitor hemoglobin and hematocrit levels. These values indicate the oxygen-carrying capacity of the blood, which directly relates to the treatment of anemia. White blood cell count (A), platelet count (C), and blood urea nitrogen (BUN) and creatinine (D) are not specific indicators of the effectiveness of epoetin alfa in treating anemia.
3. After abdominal surgery, an adult is now alert and oriented. What position is most appropriate for the client?
- A. Semi-Fowler's
- B. Prone
- C. Supine
- D. Sim's
Correct answer: A
Rationale: The most appropriate position for a client following abdominal surgery is Semi-Fowler's. This position promotes greater thoracic expansion and reduces pressure on the suture line, aiding in respiratory function and preventing strain on the incision site. Choices B, C, and D are incorrect. Prone position (Choice B) would not be suitable after abdominal surgery as it can put pressure on the abdomen. Supine position (Choice C) may cause discomfort and strain on the incision area. Sim's position (Choice D) is primarily used for rectal exams and enemas, which are unrelated to the needs post-abdominal surgery.
4. When taking a client's blood pressure, the healthcare professional is unable to distinguish the point at which the first sound was heard. What is the best action for the healthcare professional to take?
- A. Deflate the cuff completely and immediately reattempt the reading.
- B. Reinflate the cuff completely and leave it inflated for 90 to 110 seconds before taking the second reading.
- C. Deflate the cuff to zero and wait 30 to 60 seconds before reattempting the reading.
- D. Document the exact level visualized on the sphygmomanometer where the first fluctuation was seen.
Correct answer: C
Rationale: The correct action when unable to distinguish the point of the first sound during blood pressure measurement is to deflate the cuff to zero and wait 30 to 60 seconds before reattempting the reading. This allows blood flow to return to the extremity, ensuring a more accurate reading the second time. It is important to ensure that the cuff is fully deflated and the appropriate wait time is given to obtain an accurate blood pressure measurement.
5. A client is admitted with a diagnosis of fluid volume deficit. Which clinical finding would the nurse expect?
- A. Bounding pulse
- B. Bradycardia
- C. Oliguria
- D. Dry mucous membranes
Correct answer: D
Rationale: Dry mucous membranes (D) are a common clinical finding indicating fluid volume deficit. In dehydration, there is insufficient fluid in the body, leading to dry mucous membranes due to decreased saliva production. Bounding pulse (A) is associated with fluid volume excess, not deficit. Bradycardia (B) and oliguria (C) are not typical clinical findings of fluid volume deficit but may be seen in fluid volume excess or other conditions.
