Fundamentals HESI

Correct Answer: D

Rationale: The correct answer is to change the administration set every 72 to 96 hours. This practice helps reduce the risk of infection by preventing the build-up of bacteria in the tubing. Changing the set too frequently (choices A, B, and C) may increase the chances of contamination and infection without providing additional benefits. Therefore, the LPN should follow the guideline of changing the administration set every 72 to 96 hours to maintain the client's safety during the continuous intravenous normal saline infusion.

Correct Answer: D

Rationale: Choice D is the correct answer because having the 4-year-old help feed the four-month-old a bottle in the kitchen while the mother makes supper shows supervision of the infant by the older child in a safe environment. This choice indicates that the mother understands safety precautions by involving the older child in a caregiving task under her supervision. Choices A, B, and C are incorrect because they involve unsafe practices such as placing the infant on the floor unsupervised, positioning the infant car seat in the front seat, and not providing direct supervision of the children during naptimes.

Correct Answer: A

Rationale: The nurse should advise the client to document the exact medication taken to identify potential allergies and prevent adverse reactions. This is important as the client developed a rash previously while taking an antibiotic, indicating a possible allergic reaction. Choice B is not appropriate as switching antibiotics without proper evaluation can be risky. Choice C is incorrect as rashes should not be dismissed without further investigation, especially in the context of taking medication. Choice D is also not recommended as re-taking the same antibiotic without clarifying the allergic reaction can lead to a potentially severe outcome.

Correct Answer: A

Rationale: The correct answer is A: Chamomile. Chamomile tea is commonly used for stress relief. Choice B, Ginseng, is not typically used in teas for stress relief but for energy and immune system support. Choice C, Ginger, is more commonly used for digestive health and nausea. Choice D, Echinacea, is often used to boost the immune system. Therefore, in the context of stress relief, Chamomile is the most appropriate ingredient.

Correct Answer: B

Rationale: The correct answer is B: Crackles in the lungs. Crackles in the lungs indicate pulmonary congestion, a serious complication of left-sided heart failure. The presence of crackles suggests fluid accumulation in the lungs, impairing gas exchange and potentially leading to respiratory distress. Immediate intervention is necessary to prevent worsening respiratory function. Choices A, C, and D are incorrect: Peripheral edema is a common finding in heart failure but may not be as acutely concerning as pulmonary congestion. Jugular vein distention is associated with right-sided heart failure, not left-sided heart failure. Hepatomegaly is often seen in liver conditions and right-sided heart failure, not specifically left-sided heart failure.
