Fundamentals of Nursing HESI

Correct Answer: C

Rationale: During a mass casualty event, the priority client for the nurse is the one with partial-thickness and full-thickness burns to the face, neck, and chest. Clients with severe burns in critical areas require immediate attention due to the potential for life-threatening complications such as airway compromise, fluid loss, and infection. Crush injuries and fractures, although serious, are generally less urgent in comparison and can be managed after addressing the burns. Therefore, the client with burns to the face, neck, and chest should be the nurse's priority over the other clients described.

Correct Answer: A

Rationale: The correct action for the nurse to take when the urine bag has not filled for 2 hours is to check if the tubing is kinked. Kinks in the tubing can obstruct the flow of urine from the catheter, leading to decreased drainage. Increasing the IV fluid rate is not the appropriate initial action in this situation as the primary concern is with the catheter drainage. Checking the catheter insertion site would be secondary to ensuring proper drainage. Contacting the healthcare provider is not necessary as the issue can often be resolved by checking for simple tubing obstructions first.

Correct Answer: A

Rationale: To maintain the patency of a nasogastric (NG) tube, it is essential to flush the tube with 30 ml of water before and after medication administration. This action helps ensure that the tube remains open and free from blockages. Flushing the tube prevents any medication residue from causing blockages, maintaining its patency. Choice B is incorrect because administering medication with food does not relate to maintaining tube patency. Choice C is incorrect as verifying tube placement by aspirating stomach contents is related to confirming correct tube placement, not maintaining patency. Choice D is also incorrect because diluting the medication with normal saline is not primarily aimed at maintaining the tube's patency.

Correct Answer: A

Rationale: To calculate the total amount of heparin received, multiply the infusion rate (50 ml/hour) by the total infusion time (5.5 hours). This results in 275 ml of the solution infused. Since there are 20,000 units of heparin in 500 ml, there are 800 units per ml. Therefore, 275 ml contains 220,000 units. However, the heparin is diluted in 500 ml, so the client has received half of this amount, which is 110,000 units. Therefore, the correct answer is 11,000 units. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.

Correct Answer: A

Rationale: The correct answer is A: Pain related to ischemia. This nursing diagnosis should have priority because addressing the pain caused by ischemia is crucial in managing the client's myocardial infarction. Pain management is essential not only for the client's comfort but also for improving outcomes and reducing complications. Choices B, C, and D are not the priority in this scenario. Risk for altered elimination: constipation (Choice B) is not as immediate a concern as managing the client's pain. Risk for complication: dysrhythmias (Choice C) may be a potential concern but addressing the client's pain takes precedence. Anxiety related to pain (Choice D) is important to address but should come after managing the pain itself.
