HESI Fundamentals 2023 Quizlet

Correct Answer: A

Rationale: The correct time to collect a sputum specimen for culture and sensitivity is in the morning upon rising. This timing ensures the most concentrated sample as sputum produced overnight tends to accumulate and sit in the airways, providing a quality sample for testing. Collecting the specimen immediately after eating breakfast (choice B) may introduce food particles that could contaminate the sample. Collecting it before bed (choice C) may lead to a diluted sample due to daily activities. Collecting the specimen after having a drink of water (choice D) can also result in a diluted sample, impacting the accuracy of the test results.

Correct Answer: A

Rationale: The correct action for the nurse to take when applying a thigh-length sequential compression device to a postoperative client is to ensure that two fingers can fit under the sleeves. This action helps prevent the device from being too tight, which could impede circulation. Choice B is incorrect because the device should not be too tight, as it could lead to circulation issues. Choice C is incorrect as the client should be in a comfortable position, not necessarily supine. Choice D is incorrect as sequential compression devices are typically used continuously to prevent blood clots.

Correct Answer: C

Rationale: An increasing pulse rate can be an early sign of poor oxygenation as the body tries to compensate. Abnormal breath sounds (choice A) can indicate respiratory issues, but they may not always be an early sign of poor oxygenation. Cyanosis of the lips (choice B) is a late sign of inadequate oxygenation. A pulse oximeter reading of 92% (choice D) indicates mild hypoxemia but may not be considered an early indication of poor oxygenation.

Correct Answer: C

Rationale: The correct intervention for an employee exposed to an unknown dry chemical is to brush off the chemical from the skin and clothing. This helps prevent further skin contact before irrigation can be done. Irrigating the affected area with running water is crucial after brushing off the chemical to minimize the exposure. Washing the affected area with antibacterial soap is not appropriate for chemical burns, as soap can react with certain chemicals and worsen the situation. Leaving the clothing in place until emergency personnel arrive may allow the chemical to continue to harm the skin and should be avoided.

Correct Answer: A

Rationale: The correct response is A, "You're concerned about what will happen when you leave the hospital?" This response acknowledges the client's concerns about the future, validating their feelings and encouraging open communication. It shows empathy and allows the client to express their worries. Choice B minimizes the client's concerns by suggesting that they won't need to worry if they work hard on physical therapy, which may invalidate their emotions. Choice C dismisses the client's worry, implying that they should ignore their concerns to focus on getting well. Choice D uses a confrontational approach by questioning the client's concerns, which may discourage open communication and make the client feel defensive.
