Fundamentals of Nursing HESI

Correct Answer: D

Rationale: The correct answer is D. When taking isoniazid, alcohol consumption should be avoided as it can increase the risk of liver damage, potentially leading to drug-induced hepatitis. Choices A, B, and C are incorrect. Prolonged use of isoniazid does not typically cause dark concentrated urine; it is not necessary to take the medication on an empty stomach for optimal absorption; and it is not recommended to take isoniazid with aluminum hydroxide to minimize GI upset.

Correct Answer: A

Rationale: The correct answer is A: Cotton balls. Cotton balls are not suitable for tracheostomy care due to the risk of lint and contamination. When performing tracheostomy care, sterile supplies such as sterile gloves, a suction catheter, and tracheostomy tubes are essential. Sterile gloves are needed to maintain asepsis, a suction catheter is necessary for airway clearance, and tracheostomy tubes are crucial for maintaining a patent airway. Cotton balls should be avoided to prevent introducing lint or fibers into the tracheostomy site, which can lead to infection or airway obstruction.

Correct Answer: D

Rationale: The correct answer is D: 'I can take aspirin if I have a headache.' This statement indicates a need for further teaching because aspirin can increase the risk of bleeding in clients taking warfarin. Clients on warfarin therapy should avoid taking aspirin or other medications that increase the risk of bleeding. Choices A, B, and C are correct statements that show understanding of warfarin therapy, such as the importance of avoiding foods high in vitamin K, taking medication consistently, and using a soft toothbrush to prevent gum bleeding.

Correct Answer: C

Rationale: Infusing 10% dextrose and water at 54 ml/hr is the correct action to prevent hypoglycemia until the next TPN solution becomes available. This solution will help maintain the client's glucose levels. Infusing normal saline at a keep-vein-open rate (Choice A) is not appropriate for maintaining glucose levels and would not address the nutritional needs provided by TPN. Discontinuing the IV and flushing the port with heparin (Choice B) is unnecessary and not indicated in this situation as the client still needs fluid and nutrition. Obtaining a stat blood glucose level and notifying the healthcare provider (Choice D) can be done later but is not the immediate action required when the TPN solution has run out.

Correct Answer: B

Rationale: Using a regular blood pressure cuff on a morbidly obese client will lead to a falsely high blood pressure reading. This occurs because the cuff is not appropriately sized for the client's arm circumference, resulting in increased pressure on the artery and an inaccurate high reading. Choice A is incorrect because the reading will be falsely high, not low. Choice C is incorrect as the reading will not be accurate with an incorrectly sized cuff. Choice D is incorrect because the reading will be affected by using the wrong cuff size.
