HESI LPN
HESI Fundamentals Exam Questions
Question 1 of 5
A healthcare professional is obtaining the blood pressure in a client's lower extremity. Which of the following actions should the healthcare professional take?
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.
Question 2 of 5
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:
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.
Question 3 of 5
The mother of a toddler calls the nurse for help as the baby is choking on his food. The nurse determines that the Heimlich maneuver is necessary based on which finding?
Correct Answer: A
Rationale: The correct answer is option A: Inability of the toddler to cry or speak. In cases of choking, the inability to cry or speak indicates a severe airway obstruction where the Heimlich maneuver is necessary to clear the obstruction and establish a patent airway. Option B, coughing forcefully, represents a partial obstruction where the child can still move air, making the Heimlich maneuver not immediately necessary. Option C, gagging but able to breathe, suggests a partial obstruction where air is moving, and the child can still breathe, not requiring immediate intervention like the Heimlich maneuver. Option D, wheezing during respiration, is more indicative of a lower airway issue such as asthma rather than an upper airway obstruction that necessitates the Heimlich maneuver.
Question 4 of 5
A healthcare professional is planning to assess the abdomen of a client who reports feeling bloated for several weeks. Which of the following methods of assessment should the healthcare professional use first?
Correct Answer: A
Rationale: Inspection is the initial step in abdominal assessment as it allows the healthcare professional to visually observe any abnormalities or signs of bloating. Palpation, auscultation, and percussion are subsequent assessment techniques that follow inspection. Palpation involves feeling for tenderness, masses, or organ enlargement; auscultation is listening for bowel sounds; and percussion is used to assess the density of underlying tissues or detect the presence of fluid or air in the abdomen. In the context of a client reporting bloating, the first step should be visual inspection to gather initial information. Palpation, auscultation, and percussion come after inspection to provide a more comprehensive assessment.
Question 5 of 5
A client who is postoperative is being taught how to use a flow-oriented incentive spirometer. Which of the following instructions should be included by the nurse?
Correct Answer: C
Rationale: The correct technique for using a flow-oriented incentive spirometer involves breathing in slowly and deeply to raise the ball or piston. This action helps to expand the lungs and improve lung function. Option A is incorrect as coughing deeply after each use is not part of using the spirometer. Option B is incorrect as holding the breath for 10 seconds is not the correct instruction for using the spirometer. Option D is incorrect as exhaling forcefully before using the spirometer is not the appropriate step in using this device.
