HESI Fundamentals Exam Questions
Question 1 of 5
A healthcare professional is preparing to administer 750 mL of 0.9% sodium chloride IV to infuse over 7 hours. The healthcare professional should set the pump to deliver how many mL/hr?
Correct Answer: A
Rationale: To calculate the mL/hr rate for the infusion, divide the total volume (750 mL) by the total time (7 hours). 750 mL · 7 hours = 107 mL/hr. This means that the pump should be set to deliver approximately 107 mL/hr. Choice B (75 mL/hr) is incorrect because it does not reflect the correct calculation. Choice C (90 mL/hr) is incorrect as it does not align with the accurate calculation. Choice D (60 mL/hr) is incorrect as it does not match the correct mL/hr rate obtained through the calculation.
Question 2 of 5
A middle adult client tells the nurse, 'I feel so useless now that my children do not need me anymore.' Which of the following responses should the nurse make?
Correct Answer: A
Rationale: The correct response is A. Middle adulthood is a stage where individuals often experience generativity, finding fulfillment in guiding and nurturing others. By acknowledging this aspect, the nurse can help the client explore opportunities to engage in activities that provide a sense of purpose and satisfaction. Choice A validates the client's feelings and offers a constructive way to address them. Choices B, C, and D do not address the client's emotional need for purpose and may not encourage the client to seek meaningful ways to address their feelings of uselessness.
Question 3 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 4 of 5
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?
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.
Question 5 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.
