HESI Fundamentals Practice Questions

Correct Answer: B

Rationale: The correct answer is B. Petroleum jelly is flammable and should not be used with oxygen therapy as it can increase the risk of fire. Using petroleum jelly near oxygen can lead to a fire hazard. Choices A, C, and D are correct statements that indicate proper understanding of oxygen therapy safety measures. Choice A emphasizes the importance of keeping the oxygen tank upright to prevent leaks, choice C highlights the necessity of avoiding smoking to prevent exacerbation of COPD, and choice D encourages seeking medical help promptly in case of breathing difficulties.

Correct Answer: B

Rationale: The correct action in this scenario is to disconnect the electronic blood pressure machine and measure the client's blood pressure manually every 15 minutes. Given that the machine is malfunctioning and providing inconsistent readings, relying on manual measurements ensures accuracy and maintains the quality of care. Notifying the manufacturer (Choice A) may be necessary in the long run, but the immediate concern is the accuracy of the vital signs. Adjusting the machine settings again (Choice C) without resolving the underlying issue would not address the problem. Ignoring the extra readings (Choice D) could lead to incorrect assessment and compromise patient care. Therefore, the best course of action is to disconnect the machine and opt for manual blood pressure measurements until the issue is resolved.

Correct Answer: C

Rationale: The nurse should notify the admissions office and wait to apply the bracelet. By doing so, the nurse ensures patient safety and accuracy in identification. Changing the incorrect item (Choice A) could lead to errors and confusion in the patient's identification. Using the mismatched items until a replacement is supplied (Choice B) compromises patient safety and could result in errors during care delivery. Making a corrected identification bracelet without verifying the correct information (Choice D) could introduce further inaccuracies and risks in patient identification.

Correct Answer: B

Rationale: The correct answer is B: Increased urine output. In diabetes insipidus, there is a deficiency of antidiuretic hormone (ADH), leading to the excretion of large amounts of dilute urine. Reporting increased urine output is crucial as it is a hallmark sign of diabetes insipidus. Weight gain (choice A) is not typically associated with diabetes insipidus; instead, clients may experience weight loss due to fluid loss. Low blood pressure (choice C) can be a complication of diabetes insipidus due to dehydration from excessive urination, but the priority finding to report is the increased urine output. Thirst (choice D) is a common symptom of diabetes insipidus due to the body's attempt to compensate for fluid loss, but it is not the most critical finding to report.

Correct Answer: C

Rationale: The correct action for the nurse to take in this situation is to initiate contact precautions. MRSA (Methicillin-resistant Staphylococcus aureus) is a highly contagious bacterium that spreads through direct contact. Contact precautions involve wearing gloves and gowns to prevent the spread of infection to other patients or healthcare workers. Force-feeding oral fluids, requesting a nutrition consult, or limiting visitors to immediate family only are not the most appropriate actions in this scenario. These actions do not directly address the need to prevent the spread of MRSA, which is crucial in a healthcare setting.
