HESI Fundamentals Practice Questions

Correct Answer: B

Rationale: Cyanosis, a bluish discoloration of the skin, indicates inadequate oxygenation and requires immediate intervention. It suggests a severe lack of oxygen in the blood, which can be life-threatening. Pallor and jaundice are concerning findings but may not indicate an immediate life-threatening situation. Pallor can be a sign of anemia or low blood pressure, while jaundice may indicate liver dysfunction. Erythema, which is redness of the skin, is typically not an emergency and can be caused by various factors such as inflammation or increased blood flow to the area.

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: Placing the client's arm in a dependent position is the correct action when inserting a peripheral IV catheter for an older adult client. This position helps veins dilate due to gravity, facilitating easier insertion of the IV catheter. Choice A is incorrect because catheters are typically inserted at a lower angle, around 10-30 degrees. Choice C is unnecessary unless excessive hair impedes the insertion process. Choice D is incorrect as veins in the hand are generally smaller and more prone to complications, making them less ideal for IV therapy in older adults.

Correct Answer: C

Rationale: Assessing the client's health risks is the priority as it provides essential information to guide subsequent care. By understanding the client's health risks, the nurse can tailor health education and interventions, such as immunizations and lifestyle modifications, to address specific needs. Providing information about immunization against meningitis (Choice A) is important but should come after assessing health risks. Instructing the client to have a TB skin test every 2 years (Choice B) is relevant but not the initial step in care. Teaching about exercise recommendations (Choice D) is also essential but should follow the assessment of health risks.

Correct Answer: B

Rationale: The correct answer is B: 'Changing the patient's position.' Repositioning the patient involves physically moving and adjusting their position in bed, which is a task that can be safely delegated to nursing assistive personnel (NAP). This task does not require clinical judgment or assessment skills beyond the ability to follow guidelines for proper positioning. Choices A, C, and D involve assessments or judgments that require a higher level of training and knowledge, making them more appropriate for a nurse to perform. Choice A involves assessing comfort, which may involve subjective factors and individual preferences. Choice C involves identifying hazards related to immobility, which requires understanding the potential risks and complications associated with immobility. Choice D involves assessing circulation, which requires a higher level of clinical knowledge and understanding of circulatory issues.
