HESI Fundamentals Practice Exam

Correct Answer: D

Rationale: The nurse should carefully monitor serum sodium levels for a client with an NG tube on suction for an extended period due to potential fluid loss and the risk of developing hyponatremia, an electrolyte imbalance. Hyponatremia can occur as a result of continual suctioning leading to fluid loss, making it crucial to monitor sodium levels to prevent complications associated with low sodium levels. Monitoring white blood cell count, albumin, or calcium is not directly related to the impact of NG tube suction on fluid and electrolyte balance, so these values are not the priority in this scenario.

Correct Answer: D

Rationale: When a client becomes angry while waiting for a supervised break, it is essential to address their concerns effectively. Reviewing the schedule of outdoor breaks with the client provides concrete information, helps manage the client's expectations, and may alleviate their frustration. This intervention promotes transparency and empowers the client by clarifying the timing of their desired break, fostering a therapeutic and collaborative nurse-client relationship. Encouraging the client to use a nicotine patch (Choice A) does not address the client's immediate frustration with the break schedule. Reassuring the client about another break (Choice B) may temporarily placate them but does not address the underlying issue. Having the client leave the unit with another staff member (Choice C) may not be feasible or appropriate at that moment and does not address the client's concerns.

Correct Answer: A

Rationale: A decrease in cardiac output can lead to decreased blood flow to the kidneys, resulting in decreased urine output. The kidneys rely on adequate blood supply to filter waste and produce urine. Therefore, a decreased urine output is a common observation when cardiac output is reduced. Choices B, C, and D are incorrect. Increased urine output is not typically associated with decreased cardiac output; flushing of the skin is more related to vasodilation, and hyperventilation is not directly linked to decreased cardiac output.

Correct Answer: D

Rationale: The correct response when a student nurse is caught taking a copy of a client's medication administration record is to explain that the records are hospital property and cannot be removed. It is essential to educate the student about the confidentiality and security of patient information, emphasizing that even with the client's consent, such actions are unacceptable. Option A is not the immediate action needed, as addressing the student directly should come first. Option B involves notifying another party before addressing the student directly. Option C is incorrect because even if the client gave permission, patient records are confidential and cannot be shared without authorization.

Correct Answer: D

Rationale: Dry mucous membranes (D) are a common clinical finding indicating fluid volume deficit. In dehydration, there is insufficient fluid in the body, leading to dry mucous membranes due to decreased saliva production. Bounding pulse (A) is associated with fluid volume excess, not deficit. Bradycardia (B) and oliguria (C) are not typical clinical findings of fluid volume deficit but may be seen in fluid volume excess or other conditions.
