HESI Fundamentals Practice Questions

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: B

Rationale: The correct action for the nurse to take is to notify the healthcare provider. In this situation, involving the healthcare provider ensures appropriate review and adherence to legal and ethical standards based on the living will and durable power of attorney. Referring to the risk manager may not be directly related to the immediate decision-making process regarding the ventilator. Discontinuing the ventilator without proper authorization from the healthcare provider could lead to legal and ethical implications. Reviewing the medical record alone may not provide guidance on how to proceed with the specific instructions from the living will and durable power of attorney.

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: 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: A

Rationale: The correct first action for the nurse to take when a client removes the covering from an ice pack is to observe the appearance of the skin under the ice pack. This assessment is crucial to check for any skin damage or adverse reactions resulting from direct contact with the ice pack. Instructing the client about the importance of the covering (Choice B) can follow the skin assessment. Reapplying the covering (Choice C) before skin assessment may potentially cause harm. Asking the client about the duration of ice application (Choice D) is not the immediate priority; ensuring skin integrity is the primary concern.
