HESI Fundamentals Exam

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.

Correct Answer: A

Rationale: The correct action the nurse should take first is to auscultate bowel sounds. This step is crucial to assess bowel activity before proceeding with palpation or administering medications. Assessing bowel sounds can provide valuable information about bowel motility and potential obstructions. Administering an antiemetic or offering pain medication may be necessary but should come after assessing bowel sounds to ensure appropriate treatment. Palpating the abdomen should be avoided initially to prevent potential discomfort or complications, especially if there is suspected abdominal pathology.

Correct Answer: C

Rationale: The correct answer is C: Identifying the client's medication allergies. This is the priority action before administering any medication to prevent allergic reactions or adverse effects. Teaching the client about the medication's purpose is important for client understanding but not as critical as ensuring the absence of allergies. While giving medication at the prescribed time is crucial, verifying allergies takes precedence to ensure patient safety. Documenting the client's anxiety level is relevant for holistic care but is not the priority compared to ensuring safe medication administration.

Correct Answer: D

Rationale: No special preparation is required for a Venous Doppler evaluation. Option A is incorrect because there is no need for the client to be NPO (nothing by mouth) before this test. Option B is incorrect as sedative medication is not typically administered for a Venous Doppler evaluation. Option C is incorrect as discontinuing anticoagulant therapy before the test may not be safe for a client with DVT, as it could increase the risk of developing a blood clot. Therefore, the correct answer is D.

Correct Answer: B

Rationale: The toddler with severe deep abrasions covering 98% of the body would be prioritized for treatment last because these extensive injuries may require immediate attention and resources. The other choices present serious conditions but are not as severe or life-threatening as the toddler's injuries. The infant with an intermittent bulging anterior fontanel may have signs of increased intracranial pressure, requiring prompt evaluation. The preschooler's fractures, though serious, can be managed without immediate critical intervention. The school-age child with singed eyebrows and hair may have suffered burns but does not exhibit injuries as severe as the toddler's deep abrasions.
