HESI LPN
HESI Practice Test for Fundamentals Questions
Question 1 of 5
The client is advised to take dexamethasone (Decadron) with food or milk. What is the physiological basis for this advice?
Correct Answer: B
Rationale: The correct answer is B: Stimulates hydrochloric acid production. Dexamethasone can stimulate the production of hydrochloric acid in the stomach, which may lead to irritation of the stomach lining. Taking dexamethasone with food or milk helps to neutralize or buffer the acid, reducing the risk of stomach irritation. Choice A is incorrect because dexamethasone does not inhibit pepsin production. Choice C is incorrect as dexamethasone does not slow stomach emptying time. Choice D is incorrect as dexamethasone does not reduce hydrochloric acid production.
Question 2 of 5
Which task can the RN delegate to an unlicensed assistive personnel (UAP)?
Correct Answer: C
Rationale: The correct answer is C. Checking the blood pressure of a 2-hour postoperative client is a task that can be safely delegated to an unlicensed assistive personnel (UAP) as it falls within their scope of practice. This task is routine and does not require specialized nursing knowledge or critical decision-making. Options A, B, and D involve tasks that require a higher level of training and critical thinking beyond the scope of a UAP. Taking a history, adjusting tube feeding rates, and monitoring a client receiving chemotherapy are responsibilities that should be performed by licensed healthcare providers who have the necessary skills and training.
Question 3 of 5
Which nursing diagnosis would be a priority for a client admitted with a CVA (cerebral vascular accident)?
Correct Answer: A
Rationale: The correct answer is 'Risk for aspiration' as it is a priority concern in clients with a CVA due to potential swallowing difficulties. Aspiration poses immediate risks such as pneumonia, which can be life-threatening. Impaired physical mobility, while important, may not be as urgent as the risk for aspiration in this scenario. Disturbed sensory perception and interrupted family processes are not typically the most critical concerns in the acute phase of a CVA.
Question 4 of 5
A client is receiving chemotherapy for breast cancer. Which laboratory value would be most important for the nurse to monitor?
Correct Answer: A
Rationale: The correct answer is to monitor the white blood cell count. Chemotherapy can lead to neutropenia, which is a decrease in white blood cells, particularly neutrophils. Neutropenia increases the risk of infections, making it crucial to monitor the white blood cell count during chemotherapy. Monitoring hemoglobin level is important but not as critical as white blood cell count in this scenario. Serum creatinine and blood glucose levels are not directly impacted by chemotherapy for breast cancer, making them less relevant to monitor in this situation.
Question 5 of 5
The healthcare provider is assessing a client diagnosed with rheumatoid arthritis. Which assessment finding would be most concerning?
Correct Answer: D
Rationale: Fever in a client with rheumatoid arthritis can indicate an underlying infection or a more serious systemic involvement, such as vasculitis or inflammation of internal organs. These conditions can lead to serious complications and require immediate medical attention. Joint deformities and morning stiffness are common manifestations of rheumatoid arthritis itself and may not be indicative of an acute issue. Weight loss can be seen in chronic inflammatory conditions like rheumatoid arthritis but is not as concerning as fever, which suggests an acute process requiring prompt evaluation and intervention.
