HESI Fundamentals Practice Questions

Correct Answer: B

Rationale: The nurse demonstrated responsibility by recognizing the potential harm of administering an antibiotic the client is allergic to and taking the necessary steps to ensure the client's safety. Choice A, 'Fairness,' is not applicable in this scenario as it does not involve treating individuals equitably. Choice C, 'Risk-taking,' is incorrect as the nurse's actions aimed to minimize risks rather than taking them. Choice D, 'Creativity,' is not the best fit as the nurse's actions focused on following established protocols and ensuring patient safety rather than thinking innovatively.

Correct Answer: A

Rationale: To ensure accurate testing, a minimum amount of stool is required for specimen collection, typically at least 2 inches of formed stool. This amount provides an adequate sample for testing. Wearing sterile gloves is important for infection control but is not specifically required for stool specimen collection. Using a culturette is not typically necessary for collecting stool specimens. Recording the date and time the stool was collected is essential to ensure timely processing but does not directly impact the collection of the specimen itself.

Correct Answer: B

Rationale: A peak flow meter is used to measure forced expiratory volume, which helps in monitoring asthma. This measurement provides valuable information about how well the client's lungs are functioning and how narrow their airways are. Choice A is incorrect because determining oxygen saturation is typically done using a pulse oximeter. Choice C is incorrect as a peak flow meter is not used to monitor the atmosphere for allergens but rather to assess lung function. Choice D is incorrect as providing metered doses for inhaled bronchodilators is the function of a metered-dose inhaler, not a peak flow meter.

Correct Answer: B

Rationale: Fasting can lead to an increased protein-binding response of medications. This can result in a higher concentration of bound medications in the bloodstream, potentially causing toxicity as the medications may not be readily available for metabolism or excretion. Choice A is incorrect because fasting typically doesn't increase medication metabolism. Choice C is incorrect as fasting usually decreases transit time through the intestines. Choice D is incorrect since fasting generally does not decrease medication excretion.

Correct Answer: B

Rationale: The correct action in this scenario is to disconnect the electronic blood pressure machine and measure the client's blood pressure manually every 15 minutes. Given that the machine is malfunctioning and providing inconsistent readings, relying on manual measurements ensures accuracy and maintains the quality of care. Notifying the manufacturer (Choice A) may be necessary in the long run, but the immediate concern is the accuracy of the vital signs. Adjusting the machine settings again (Choice C) without resolving the underlying issue would not address the problem. Ignoring the extra readings (Choice D) could lead to incorrect assessment and compromise patient care. Therefore, the best course of action is to disconnect the machine and opt for manual blood pressure measurements until the issue is resolved.
