Nursing Elites

1. During transfusion of a unit of whole blood, a nurse is assessing a client who develops a cough, shortness of breath, elevated blood pressure, and distended neck veins. The nurse should anticipate a prescription for which of the following medications?

• A. Epinephrine
• B. Lorazepam
• C. Furosemide
• D. Diphenhydramine

Correct answer: C

Rationale: The client's symptoms indicate circulatory overload, which can occur during blood transfusions. Furosemide, a loop diuretic, is commonly prescribed in such cases to help relieve manifestations of circulatory overload by promoting diuresis and reducing fluid volume. Epinephrine is used for severe allergic reactions, lorazepam for anxiety or seizures, and diphenhydramine for mild allergic reactions or as a sedative. Therefore, the correct choice is Furosemide (C) to manage circulatory overload during a blood transfusion.

2. A client has a new prescription for Furosemide. Which of the following adverse effects should the nurse monitor?

• A. Hyperkalemia
• B. Hyponatremia
• C. Hypernatremia
• D. Hypercalcemia

Correct answer: B

Rationale: The correct answer is B: Hyponatremia. Furosemide, a diuretic, commonly causes hyponatremia (low sodium levels) as it increases the excretion of sodium. The nurse needs to monitor the client for signs of hyponatremia, such as confusion, weakness, and muscle cramps, by checking electrolyte levels regularly. Choices A, C, and D are incorrect because hyperkalemia (choice A), hypernatremia (choice C), and hypercalcemia (choice D) are not typically associated with Furosemide use.

3. What is the pharmacological action of metformin?

• A. Blocks stimulation of beta1 and beta2.
• B. Blocks vasoconstriction and aldosterone.
• C. Acts at many levels in the CNS to produce an anxiolytic effect.
• D. Decreases hepatic glucose production.

Correct answer: D

Rationale: The correct answer is D: Decreases hepatic glucose production. Metformin's primary pharmacological action is to decrease hepatic glucose production, leading to lower blood sugar levels and improved insulin sensitivity in the liver. Choices A, B, and C are incorrect because metformin does not block stimulation of beta1 and beta2 receptors, vasoconstriction, aldosterone, or act in the CNS to produce an anxiolytic effect. Therefore, these options are not reflective of metformin's mechanism of action.

4. A client is admitted for a surgical procedure. Which of the following preexisting conditions can be a contraindication for the use of Ketamine as an intravenous anesthetic?

• A. Peptic ulcer disease
• B. Breast cancer
• C. Diabetes mellitus
• D. Schizophrenia

Correct answer: D

Rationale: Ketamine is known to produce psychological effects, such as hallucinations. Therefore, individuals with schizophrenia are at increased risk of experiencing exacerbation of their symptoms if given Ketamine, making it a contraindication for its use as an intravenous anesthetic. Peptic ulcer disease, breast cancer, and diabetes mellitus are not contraindications for Ketamine use as an intravenous anesthetic.

5. When teaching a client with a prescription for Cephalexin, which of the following instructions should the nurse include?

• A. Take the medication with an antacid.
• B. Avoid dairy products while taking this medication.
• C. Expect your stools to turn black.
• D. Complete the full course of medication.

Correct answer: D

Rationale: The correct instruction for a client prescribed with Cephalexin is to complete the full course of medication. This is crucial to ensure the infection is completely treated and to reduce the risk of antibiotic resistance. Choices A, B, and C are incorrect. Taking Cephalexin with an antacid is generally not recommended as it may reduce its effectiveness. While dairy products can interfere with certain antibiotics, they do not have a direct interaction with Cephalexin. Stools turning black is not an expected side effect of Cephalexin.
