HESI Fundamentals Exam

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: A

Rationale: When measuring blood pressure in the lower extremity, the bladder of the cuff should be placed over the posterior aspect of the thigh. This positioning ensures an accurate measurement. Placing the cuff around the ankle (Choice C) or above the knee (Choice D) would not provide an accurate blood pressure reading in the lower extremity. Using a smaller cuff designed for lower extremities (Choice B) is not appropriate as the standard cuff size should be used with the bladder placed over the posterior aspect of the thigh.

Correct Answer: A

Rationale: When a client is using a nasal cannula for oxygen therapy, the areas prone to skin damage are the tops of the ears and around the nostrils. The pressure exerted by the cannula on these areas can lead to skin breakdown, so it is important for the nurse to observe these sites for any signs of damage. The correct answer is 'Tops of the ears.' Choices 'Bridge of the nose' and 'Over the cheeks' are not typically areas where skin damage related to the cannula would occur, making them incorrect choices.

Correct Answer: C

Rationale: The correct answer is C. Ensuring the oxygen equipment's wires and cables are in good working order is crucial to prevent sparks in an oxygen-rich environment, which could lead to a fire. Choices A, B, and D are incorrect because smoking near an oxygen tank, using a cotton blanket near oxygen (as cotton is less likely to generate static electricity than wool), and laying the oxygen tank down on the floor pose significant safety risks and are not appropriate practices for managing oxygen therapy at home.

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.
