Fundamentals of Nursing HESI

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: D

Rationale: The correct answer is D. When taking isoniazid, alcohol consumption should be avoided as it can increase the risk of liver damage, potentially leading to drug-induced hepatitis. Choices A, B, and C are incorrect. Prolonged use of isoniazid does not typically cause dark concentrated urine; it is not necessary to take the medication on an empty stomach for optimal absorption; and it is not recommended to take isoniazid with aluminum hydroxide to minimize GI upset.

Correct Answer: A

Rationale: The nurse's priority in this situation is to assess the client for injuries. Checking for injuries first is crucial to determine the extent of harm caused by the fall and to provide immediate care. Moving hazardous objects can wait until the client's safety is ensured. Notifying the provider and asking the client about how she felt prior to the fall are important but are secondary to assessing for injuries in this urgent scenario. It is essential to address immediate physical needs before investigating the cause of the fall or notifying other healthcare team members.

Correct Answer: B

Rationale: The correct answer is B. Going to the nurses' station for assistance during a seizure is inappropriate as immediate care is necessary. Placing the client on their side helps maintain an open airway and prevents aspiration. Noting the time the seizure begins is crucial for monitoring and documentation. Preparing to insert an airway may be necessary if the client's airway becomes compromised. Therefore, the nurse's statement about going to the nurses' station for assistance is the only incorrect response as it delays essential care.

Correct Answer: B

Rationale: When cimetidine decreases the metabolism of imipramine, it leads to an increased concentration of imipramine in the body, which can result in imipramine toxicity. This increased risk of toxicity is the likely effect of this drug interaction. Choice A is incorrect because cimetidine's effect on imipramine metabolism does not impact the therapeutic effects of cimetidine. Choice C is incorrect because the interaction does not decrease the risk of adverse effects of cimetidine. Choice D is incorrect as the increased concentration of imipramine can lead to toxicity, not increased therapeutic effects.
