HESI Fundamentals Exam Test Bank

Correct Answer: B

Rationale: Irrigating the wound with sterile normal saline is the correct technique for cleansing a wound when the prescription does not specify a cleaning method. Sterile normal saline is a standard and safe solution that helps to remove debris and promote healing without damaging healthy tissue. Choice A, using povidone-iodine solution, can be cytotoxic and delay wound healing. Choice C, using hydrogen peroxide, can be cytotoxic, cause tissue damage, and delay wound healing. Choice D, using wet-to-dry dressing to remove eschar, is an outdated and non-selective method that can cause trauma to the wound bed and delay healing. Therefore, choice B is the best option for wound cleansing in this scenario.

Correct Answer: A

Rationale: The correct answer is A. Using non-acetone nail polish remover is crucial for clients on supplemental oxygen as acetone is flammable and poses a safety risk. Acetone can react with oxygen, increasing the fire hazard. Choices B, C, and D are incorrect. Electric razors can generate sparks, which are dangerous near oxygen due to the risk of ignition. While cleaning oxygen equipment is important, the type of nail polish remover used is more critical for immediate safety. Wool blankets can create static electricity, increasing the risk of fire around oxygen due to its flammability.

Correct Answer: B

Rationale: To calculate the flow rate in drops per minute (gtt/min), the formula is Total volume (mL) � Time (min) � Drop factor (gtt/mL). In this case, 1000 mL � 240 min � 20 gtt/mL = 83 gtt/min. Therefore, setting the flow rate to 83 gtt/min ensures the correct administration of the IV fluids and medication. Choices A, C, and D are incorrect as they do not align with the correct calculation based on the provided information.

Correct Answer: D

Rationale: The correct answer is D because in middle adulthood, individuals often shift their focus towards concerns related to the next generations. They reflect on their roles in guiding and supporting the younger generations. Choice A is incorrect as evaluating behavior after a social interaction is more relevant to self-awareness, which is not a specific developmental task for middle adulthood. Choice B, learning to trust others, is more commonly associated with early adulthood tasks related to forming intimate relationships. Choice C, wishing to find meaningful friendships, is more aligned with tasks associated with young adulthood and social connections.

Correct Answer: B

Rationale: The correct answer is B: Preschooler. Family customs have a significant impact on hygiene practices during childhood, especially in the early years. Preschoolers are at an age where they are learning and forming habits, and family customs play a crucial role in establishing routines such as bathing and brushing teeth. Adolescents, older adults, and adults are more likely to have established their own hygiene routines that may not be as heavily influenced by family customs as in early childhood. Therefore, the nurse is most likely providing care to a preschooler in this scenario.
