Nursing Elites

1. In reviewing a client's health record, which condition would be a contraindication for using Propranolol to treat hypertension?

• A. Asthma
• B. Glaucoma
• C. Hypertension
• D. Tachycardia

Correct answer: A

Rationale: Propranolol is a nonselective beta-adrenergic blocker that blocks both beta1 and beta2 receptors. Blocking beta2 receptors in the lungs can lead to bronchoconstriction, making it unsuitable for clients with asthma. Therefore, asthma is a contraindication for taking Propranolol. Glaucoma, hypertension, and tachycardia are not contraindications for using Propranolol to treat hypertension.

2. 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.

3. A client with Addison's disease is being admitted for a total hip arthroplasty. The client takes hydrocortisone for Addison's disease. What is the nurse's priority action?

• A. Administering a supplemental dose of hydrocortisone
• B. Instructing the client about coughing and deep breathing
• C. Collecting additional information from the client about his history of Addison's disease
• D. Inserting an indwelling urinary catheter

Correct answer: A

Rationale: The nurse's priority in this situation is to administer a supplemental dose of hydrocortisone. Clients with Addison's disease taking hydrocortisone are at risk of acute adrenal insufficiency during times of stress such as surgery. Administering supplemental doses of hydrocortisone helps prevent acute adrenal insufficiency (adrenal crisis) in these situations, making it the priority action to ensure the client's safety. Instructing the client about coughing and deep breathing is important postoperatively but not the priority at this time. Collecting additional information about the client's history of Addison's disease is important but not the priority action before surgery. Inserting an indwelling urinary catheter is not the priority in this situation.

4. A healthcare professional is reviewing the laboratory results of a client who is taking Lithium for Bipolar Disorder. Which of the following findings should the healthcare professional report to the provider immediately?

• A. Lithium level of 1.0 mEq/L
• B. Potassium level of 3.5 mEq/L
• C. Sodium level of 140 mEq/L
• D. Creatinine level of 1.0 mg/dL

Correct answer: D

Rationale: A creatinine level of 1.0 mg/dL should be reported to the provider immediately. While a lithium level of 1.0 mEq/L falls within the therapeutic range, a creatinine level of 1.0 mg/dL could suggest early signs of kidney dysfunction, especially concerning in a client on long-term lithium therapy. It is crucial to monitor kidney function closely because lithium can be nephrotoxic over time. Elevated creatinine levels may indicate impaired kidney function and should prompt immediate reporting to the healthcare provider. Potassium and sodium levels within normal range are not immediate concerns when compared to potential kidney issues.

5. When teaching a client with a new prescription for Amiodarone, which instruction should the nurse include?

• A. Take this medication with meals.
• B. Avoid drinking grapefruit juice.
• C. Take this medication at bedtime.
• D. Increase your intake of sodium-rich foods.

Correct answer: B

Rationale: The correct instruction is to avoid drinking grapefruit juice when taking Amiodarone. Grapefruit juice can inhibit the metabolism of Amiodarone, leading to increased blood levels of the drug and potentially causing adverse effects like cardiac toxicity. Choices A, C, and D are incorrect because taking Amiodarone with meals, at bedtime, or increasing sodium-rich foods intake are not relevant instructions for this medication.
