Practice HESI Fundamentals Exam

Correct Answer: B

Rationale: The most appropriate initial approach to correct the behavior of improper hand washing by a staff nurse is to discuss what the nurse knows about proper hand hygiene. This approach helps in identifying any knowledge gaps the nurse may have and provides an opportunity to educate and correct the behavior. Option A is not the best choice as simply reminding the nurse about the importance of hand washing may not address the underlying issue of knowledge or technique. Option C, providing a review of the hand washing policy, may be necessary but is not the most immediate step to take. Option D, referring the nurse to the infection control nurse, is premature and may not be necessary if the issue can be resolved through education and communication first.

Correct Answer: B

Rationale: The best initial action for a client with type 1 diabetes mellitus experiencing hypoglycemia is to give them 4 ounces of orange juice. Orange juice quickly raises blood glucose levels in a hypoglycemic client. Administering glucagon intramuscularly is not the best initial action for hypoglycemia; it is usually reserved for severe hypoglycemia cases. Giving a snack containing protein and carbohydrates is not as rapid as orange juice in raising blood glucose levels during hypoglycemia. Encouraging the client to rest until symptoms resolve does not address the immediate need to raise blood glucose levels in a hypoglycemic state.

Correct Answer: B

Rationale: The correct answer is B: Renal stones. Renal calculi are calcium stones that can form in the renal pelvis or pass through the ureters. Immobilized patients, who have hypercalcemia, are at increased risk for developing renal stones. Monitoring for signs and symptoms of renal stones is crucial in this patient population. Choices A, C, and D are incorrect because although they are potential complications in immobilized patients, they are not directly associated with hypercalcemia and do not match the scenario described in the question.

Correct Answer: B

Rationale: Correct placement of an NG tube is confirmed by aspirating gastric fluid, which indicates that the tube is in the stomach. An x-ray can help visualize tube placement, but it alone does not confirm correct placement. Flushing the tube with sterile water without resistance indicates patency but not necessarily correct placement. The absence of coughing or choking does not confirm tube placement and is more related to the client's comfort during the procedure.

Correct Answer: A

Rationale: The highest priority during an eye irrigation for a client exposed to smoke and ash is wearing gloves during the procedure. This action is crucial as it helps prevent contamination and protects both the client and the nurse. Using a sterile solution is important but not as critical as ensuring the nurse's safety by wearing gloves. Irrigating from the inner to the outer canthus and positioning the client's head properly are essential steps in eye irrigation, but they are not the highest priority in this scenario compared to ensuring infection control by wearing gloves.
