HESI Fundamentals Practice Questions

Correct Answer: B

Rationale: The presence of a non-blanching red area over the client's trochanter is a concerning finding as it indicates possible pressure ulcer formation. This finding necessitates an increase in the frequency of position changes to prevent skin breakdown. Choices A, C, and D do not directly correlate with the need for increased position changes. A flat rash, ecchymosis, and petechiae may have different causes and would not be addressed by changing the client's position more frequently.

Correct Answer: D

Rationale: The use of accessory muscles is the most concerning finding in a client with COPD. It indicates increased work of breathing and may signal respiratory distress, requiring immediate attention. Barrel chest is a common physical characteristic in individuals with COPD due to chronic air trapping and hyperinflation of the lungs but is not as acutely concerning as the use of accessory muscles. Clubbing of the fingers is a late sign of chronic hypoxia and is often seen in conditions with prolonged hypoxemia but is not as acute as the use of accessory muscles. Cough with sputum production is a common symptom in COPD due to excess mucus production but does not indicate immediate respiratory distress as the use of accessory muscles does.

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: The correct answer is to ensure the client is sitting upright while eating. This position helps prevent aspiration and facilitates swallowing. Offering tart or sour foods (Choice A) may not be suitable for someone with dysphagia as they can be difficult to swallow and may increase the risk of aspiration. Providing soft and easily swallowable foods (Choice C) is crucial for individuals with swallowing difficulties. While giving thickened liquids (Choice D) is a common intervention for dysphagia, the priority during mealtime should be ensuring the client's proper positioning to support safe swallowing and prevent aspiration.

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.
