HESI LPN
HESI Fundamentals Exam
1. A healthcare professional is planning to collect a liquid stool specimen from a client for ova and parasites. Inaccurate test results may result if the healthcare professional:
- A. Refrigerates the collected specimen
- B. Collects the specimen in a sterile container
- C. Delays the collection of the specimen
- D. Uses a non-contaminated collection container
Correct answer: A
Rationale: Refrigeration can kill the ova and parasites present in the stool specimen, leading to inaccurate test results. Storing the specimen in a cold environment can disrupt the integrity of the parasites and ova, affecting the accuracy of the test. Collecting the specimen in a sterile container (Choice B) is the correct procedure to prevent external contamination. Delaying the collection of the specimen (Choice C) may affect the freshness of the sample but does not directly impact the test results. Using a non-contaminated collection container (Choice D) is essential to maintain the sample's integrity but does not relate to the risk of killing ova and parasites through refrigeration.
2. When a healthcare professional makes an initial assessment of a client who is post-op following gastric resection, the client's NG tube is not draining. The healthcare professional's attempt to irrigate the tube with 10ml of 0.9% NaCl was unsuccessful, so they determine that the tube was obstructed. Which of the following actions should the healthcare professional take?
- A. Notify the healthcare provider.
- B. Attempt to irrigate the tube with a larger volume of saline.
- C. Replace the NG tube with a new one.
- D. Reposition the client to see if that helps the tube drain.
Correct answer: A
Rationale: If an NG tube is obstructed and cannot be irrigated successfully, notifying the healthcare provider is the appropriate action to take for further management. This is crucial as the healthcare provider may need to assess the situation, provide guidance, or intervene with specific interventions. Attempting to irrigate the tube with a larger volume of saline (Choice B) may exacerbate the situation if the tube is truly obstructed. Replacing the NG tube with a new one (Choice C) should not be the initial action unless advised by the healthcare provider. Repositioning the client (Choice D) may not necessarily resolve the tube obstruction and should not be the primary intervention in this scenario.
3. A healthcare professional is obtaining the blood pressure in a client's lower extremity. Which of the following actions should the healthcare professional take?
- A. Place the bladder of the cuff over the posterior aspect of the thigh
- B. Use a smaller cuff designed for lower extremities
- C. Place the cuff around the client's ankle
- D. Ensure the cuff is positioned above the knee
Correct answer: A
Rationale: When measuring blood pressure in the lower extremity, the bladder of the cuff should be placed over the posterior aspect of the thigh. This positioning ensures an accurate measurement. Placing the cuff around the ankle (Choice C) or above the knee (Choice D) would not provide an accurate blood pressure reading in the lower extremity. Using a smaller cuff designed for lower extremities (Choice B) is not appropriate as the standard cuff size should be used with the bladder placed over the posterior aspect of the thigh.
4. A client is scheduled for an IVP (Intravenous Pyelogram). Which of the following data from the client's history indicates a potential hazard for this test?
- A. Reflex incontinence
- B. Allergic to shellfish
- C. Claustrophobia
- D. Hypertension
Correct answer: B
Rationale: The correct answer is B, 'Allergic to shellfish.' An allergy to shellfish can indicate a sensitivity to iodine, which is used in the contrast dye for an IVP, posing a risk of an allergic reaction. Reflex incontinence (Choice A) is not directly related to the potential hazard of an IVP. Claustrophobia (Choice C) and hypertension (Choice D) are also not significant factors that indicate a potential hazard for an IVP.
5. A healthcare professional is measuring vital signs for a client and notices an irregularity in the pulse. Which of the following actions should the healthcare professional take?
- A. Count the apical pulse rate for 1 full minute, and describe the rhythm in the chart.
- B. Recheck the pulse at the same site after 5 minutes.
- C. Measure the client’s blood pressure.
- D. Record the irregularity and continue with other vital signs.
Correct answer: A
Rationale: When an irregular pulse is detected, it is essential to count the apical pulse rate for a full minute to accurately determine the rhythm. This ensures a comprehensive assessment and helps in identifying any potential issues or abnormalities. Rechecking the pulse at the same site after 5 minutes (Choice B) may not provide an immediate understanding of the irregularity. Measuring the client's blood pressure (Choice C) is important but not directly related to addressing the irregular pulse. Recording the irregularity and continuing with other vital signs (Choice D) may overlook a potentially serious cardiac issue that requires immediate attention.
