HESI Fundamentals Practice Test

Correct Answer: C

Rationale: Coughing, vomiting, and suctioning can precipitate displacement of the tip of the small-bore feeding tube upward into the esophagus, placing the client at increased risk for aspiration. Checking the sample of fluid withdrawn from the tube (after clearing the tube with 30 ml of air) for acidic (stomach) or alkaline (intestine) values is a more sensitive method for these tubes. The nurse should assess tube placement in this way before taking any other action to ensure the tube is still in the correct position and prevent potential complications. Choice A is incorrect because further assessment is needed due to the risk of tube displacement. Choice B is incorrect as stopping the feeding and involving the family is premature without confirming tube placement. Choice D is incorrect as injecting air and auscultating for gurgling is not the recommended method to confirm tube placement.

Correct Answer: B

Rationale: Applying antiembolism stockings as prescribed (B) is an effective intervention to prevent deep vein thrombosis (DVT) in a client on bed rest. While encouraging ambulation (A), elevating the legs (C), and performing passive range-of-motion exercises (D) are also beneficial, compression stockings are particularly effective in reducing the risk of DVT by promoting venous return and reducing stasis in the lower extremities.

Correct Answer: C

Rationale: The correct action is for the provider not to administer the medication and to document the reason. In the case of a minor, parental consent is required for medical treatment, including medication administration. It is important to follow legal and ethical guidelines to ensure the adolescent's well-being and rights are protected. Choice A is incorrect because simply reviewing the chart does not address the lack of parental consent. Choice B is incorrect as obtaining parental consent should be done before medication administration. Choice D is incorrect as notifying the adolescent is not the appropriate action in this situation, as parental consent is legally required for a minor's medical treatment.

Correct Answer: B

Rationale: In the scenario described, the correct action after a needle stick injury is to discard the contaminated needle safely and choose a new sterile needle to continue the procedure. This step helps prevent potential transmission of infections and ensures the safety of both the individual and the patient. Disinfecting the needle with an alcohol swab is not adequate to address the risk of infection transmission. While completing an incident report and notifying the supervisor are important, the immediate action should be to replace the contaminated needle with a new sterile one to prevent any potential harm.

Correct Answer: B

Rationale: The nurse should document a respiratory rate of 16. The second count of eight respirations in a 30-second interval is the most accurate as it was not interrupted by the client coughing. Therefore, this rate reflects the client's typical respiratory pattern and should be documented. Choices A, C, and D are incorrect as they do not consider the interruption caused by the client coughing during the first count, which could have affected the accuracy of the result. The second count of eight respirations provides a more reliable indication of the client's respiratory rate.
