HESI Fundamentals Exam

Correct Answer: B

Rationale: During a Weber test, the nurse should place an activated tuning fork in the middle of the client's forehead. This test is used to assess for lateralization of sound in a client with possible hearing issues. Choice A is incorrect because the Weber test does not involve delivering high-pitched sounds at random intervals. Choice C is incorrect as it describes the Rinne test, not the Weber test. Choice D is incorrect as whispering words into one ear is not part of the Weber test procedure.

Correct Answer: B

Rationale: Measuring the pH of the gastric aspirate is the most reliable method to confirm proper placement of an NG tube. Gastric fluid has an acidic pH, typically ranging from 1 to 5. Assessing the client for a gag reflex (choice A) is important for airway protection but does not confirm tube placement. Placing the NG tube in water to observe for bubbling (choice C) is incorrect and not a reliable method for verifying placement. Auscultating 2.5 cm above the umbilicus while injecting sterile water (choice D) is an outdated method and is not recommended for verifying NG tube placement.

Correct Answer: A

Rationale: Choice A is correct because performing ankle and knee exercises every hour helps prevent contractures and other adverse effects of immobility. Contractures are a common complication of immobility, and range of motion (ROM) exercises can help maintain joint flexibility and prevent contractures. This statement indicates an understanding of the teaching provided by the healthcare provider. Choices B, C, and D are incorrect. Holding the breath when rising from a sitting position can increase the risk of orthostatic hypotension, not reduce adverse effects of immobility. Removing antiembolic stockings while in bed can compromise their effectiveness in preventing deep vein thrombosis (DVT), which is not a measure to reduce immobility-related complications. Having a partner help change positions every 4 hours may not be frequent enough to prevent immobility-related complications effectively; changing positions more frequently is usually recommended to prevent issues like pressure ulcers and muscle stiffness.

Correct Answer: B

Rationale: The correct term the healthcare provider will use when reporting the extremely bad breath of the unconscious patient to the oncoming shift is 'Halitosis' (Choice B). Halitosis specifically refers to bad breath. Cheilitis (Choice A) is inflammation of the lips, not related to bad breath. Glossitis (Choice C) is inflammation of the tongue, not directly associated with bad breath. Dental caries (Choice D) are cavities in the teeth, which can contribute to bad breath but are not the term used to describe bad breath itself.

Correct Answer: D

Rationale: Gingival hyperplasia is a significant side effect associated with phenytoin therapy. It is characterized by an overgrowth of gum tissue, which can lead to issues such as difficulty in speaking, eating, and maintaining proper oral hygiene. This condition can progress rapidly and may require immediate intervention by the healthcare provider to prevent further complications. Increased appetite, dry mouth, and nausea/vomiting are common side effects of various medications, but they are not as urgent or serious as gingival hyperplasia in a client taking phenytoin.
