Fundamentals of Nursing HESI

1. What is the rate of delivery in mL/hr if a total volume of 750 mL is infused over a period of 7 hours?

Correct answer: A

Rationale: The correct rate of delivery is 107 mL/hr. To find the rate of delivery, divide the total volume by the total time: 750 mL / 7 hours = 107 mL/hr. Choice B, C, and D are incorrect as they do not match the correct calculation based on the total volume and time provided.

2. A client with type 2 diabetes mellitus is receiving metformin (Glucophage). Which laboratory test should the LPN/LVN monitor while the client is taking this medication?

Correct answer: B

Rationale: The correct answer is B: Liver function tests. While a client is taking metformin, monitoring liver function tests is crucial to assess for potential hepatic side effects. Metformin is primarily eliminated by the liver, and monitoring liver function tests helps in early detection of any liver-related complications. Choices A, C, and D are incorrect. A complete blood count (CBC) is not specifically required for monitoring metformin therapy. Serum electrolytes are not directly impacted by metformin, making it less relevant for monitoring this medication. Renal function tests are important for some other diabetes medications, but in the case of metformin, liver function tests take precedence due to its hepatic metabolism.

3. A post-op nurse has an indwelling catheter in place for gravity drainage. The nurse notes that the client's urine bag has been empty for 2 hours. The first action the nurse should take is to:

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.

4. A healthcare professional is reviewing the medical record of a client who has hypocalcemia. The healthcare professional should identify which of the following findings as a risk factor for the development of this electrolyte imbalance?

Correct answer: A

Rationale: Crohn’s disease is known to impair calcium absorption, which can lead to hypocalcemia. This condition affects the intestines and can disrupt the normal absorption of nutrients, including calcium. Postoperative status following appendectomy, history of bone cancer, and hyperthyroidism are typically not directly associated with a higher risk of developing hypocalcemia compared to Crohn’s disease.

5. A client with iron-deficiency anemia asks a nurse why the Z-track method is necessary for administering iron dextran. Which response should the nurse provide?

Correct answer: C

Rationale: The Z-track method is used to minimize tissue irritation by sealing the medication in the muscle. This technique helps prevent leakage of the medication into subcutaneous tissue, reducing the risk of irritation and staining at the injection site. Option A about decreasing the risk of injecting medication into a blood vessel is not correct as the primary purpose of the Z-track method is to prevent tissue irritation. Option B stating it delays medication absorption is incorrect as the Z-track method does not affect the rate of medication absorption. Option D mentioning it accelerates medication excretion is incorrect as the Z-track method does not impact medication excretion but rather focuses on minimizing tissue irritation.
