HESI Fundamentals Study Guide

Correct Answer: C

Rationale: During a thoracic examination, normal findings should include resonance, which is the expected sound when percussing the thorax. Resonance indicates healthy lung tissue and air-filled spaces. Abnormal findings such as rhonchi and crackles suggest issues like lung congestion or inflammation. Tactile fremitus refers to vibrations felt on the chest wall during palpation and is not typically assessed during percussion and auscultation of the thorax.

Correct Answer: A

Rationale: Checking the client for injuries is the priority when finding them on the bathroom floor. This action ensures the client's safety as it allows for immediate assessment of any potential harm. Calling for help may be necessary, but assessing for injuries takes precedence to address any immediate threats to the client's well-being. Moving the client to a sitting position or assisting them back to bed should only be done after ensuring there are no serious injuries requiring prompt medical attention. Therefore, the correct first action is to check the client for injuries.

Correct Answer: A

Rationale: The correct answer is A: Wear cotton clothing to avoid static electricity. When using oxygen therapy, static electricity can pose a hazard as it increases the risk of fire. Cotton clothing helps reduce static electricity buildup. Choice B, avoiding electrical appliances, is overly restrictive and not entirely necessary. Choice C, keeping the oxygen tank away from heat sources, is important to prevent fire hazards but is not directly related to the nasal cannula. Choice D, using only a specific type of nasal cannula, is not a universal guideline and limits flexibility in care.

Correct Answer: B

Rationale: For subcutaneous injections like heparin, a 25-27 gauge needle is recommended, making choice A incorrect. The abdomen is a commonly used site for heparin injection due to its consistent absorption and convenience, making choice B the correct answer. The Z-track technique is not necessary for subcutaneous injections, making choice C unnecessary. Observing for bleb formation is not a standard practice for confirming proper placement of subcutaneous heparin, making choice D incorrect. Therefore, the correct action is to select a site on the client's abdomen for the injection.

Correct Answer: A

Rationale: Explaining the procedure to the client is the initial and most important step that the healthcare professional should take before inserting an NG tube. By explaining the procedure, the healthcare professional ensures the client's understanding, obtains informed consent, and fosters cooperation. Measuring the length of the NG tube, lubricating the tube, and positioning the client in a high Fowler's position are essential steps in the NG tube insertion process but should come after the client has been informed and consented to the procedure.
