HESI Fundamentals Practice Test

Correct Answer: B

Rationale: To calculate the volume to administer, use the formula (1 mL 4 mg) / 5 mg = 0.8 mL. The healthcare provider should administer 0.8 mL of diazepam for a dosage of 4 mg IV push. Choice A is incorrect because it results from an incorrect calculation. Choices C and D are incorrect as they do not align with the correct calculation based on the provided dosage.

Correct Answer: A

Rationale: In a client with autonomic dysreflexia, the most critical action is to elevate the head of the bed to 45 degrees (A). This positioning helps reduce blood pressure, which is essential in managing autonomic dysreflexia. Monitoring the client's respiratory rate (B) is important for overall assessment but not the priority in this situation. Administering an antihypertensive medication (C) without addressing the positioning issue first can lead to further complications. Assessing the client's blood glucose level (D) is not directly related to autonomic dysreflexia and is not the initial priority in this scenario.

Correct Answer: B

Rationale: The nurse should prioritize addressing the client's emotional needs by engaging in a conversation to understand the underlying feelings behind her statement. By exploring the client's thoughts about death, the nurse can provide appropriate support and interventions tailored to the client's concerns. Rushing to administer pain medication may not address the emotional distress expressed by the client. Initiating antidepressant therapy is not suitable without assessing the client's feelings further. Referring the client to the ethics committee is premature and does not address the immediate emotional needs of the client. Therefore, empathetic communication and assessment of the client's feelings regarding her situation are crucial for providing holistic care.

Correct Answer: B

Rationale: Anticoagulants increase the risk of bleeding during surgery, which can lead to complications such as excessive bleeding and difficulty in achieving hemostasis. This poses a significant threat during a surgical procedure where controlling bleeding is crucial for a successful outcome. The other options (A, C, D) are not as critical as anticoagulants in terms of posing a threat for complications during surgery. Birth control pills, recently completing antibiotic therapy, and using laxatives do not directly impact bleeding risks during surgery compared to anticoagulants.

Correct Answer: B

Rationale: When caring for an immobile client, the nursing diagnosis with the highest priority is impaired gas exchange. This is because impaired gas exchange implies difficulty with breathing, which is essential for sustaining life. Adequate oxygenation is crucial for all bodily functions, and any impairment in gas exchange can lead to serious complications, making it the priority nursing diagnosis to address in an immobile client. Choices A, C, and D are important considerations as well when caring for an immobile client, but they are secondary to impaired gas exchange. Risk for fluid volume deficit may occur due to immobility, but ensuring proper gas exchange takes precedence as it directly impacts the client's immediate survival. Risk for impaired skin integrity is a concern in immobile clients but does not pose an immediate threat to life like impaired gas exchange. Altered tissue perfusion is also critical but is usually a consequence of impaired gas exchange, reinforcing the priority of addressing gas exchange first.
