Nursing Elites

1. The practical nurse is assigned a client on digoxin therapy. Which finding is likely to predispose this client to developing digoxin toxicity?

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

Correct answer: D

Rationale: Hypokalemia predisposes a client on digoxin to digoxin toxicity. Symptoms of digoxin toxicity include abdominal pain, anorexia, nausea, vomiting, visual disturbances, bradycardia, and atrioventricular (AV) dissociation. Therefore, assessment of serum potassium levels and prompt correction of hypokalemia are crucial interventions for clients taking digoxin.

2. In a capillary glucose measurement, a client is to receive 10 units of regular insulin and isophane insulin. How should the nurse prepare?

• A. Withdraw ten units of regular insulin from a vial
• B. Withhold the dose until regular insulin is available
• C. Obtain a new vial of regular insulin and withhold
• D. Pull up 30 units from a vial but only administer 10 units

Correct answer: B

Rationale: In insulin administration, regular insulin is typically administered before isophane insulin to manage blood glucose effectively. If regular insulin is not available, it is best to withhold the dose until it can be administered as prescribed. Choice A is incorrect as it suggests withdrawing from a specific vial without specifying regular insulin. Choice C is incorrect as obtaining a new vial of regular insulin may not be necessary if it becomes available shortly. Choice D is incorrect as administering 10 units from a mixture of regular and isophane insulin is not the correct approach.

3. A client is receiving metronidazole for Clostridium difficile pseudomembranous colitis. Which information should the nurse include in this client's medication teaching plan?

• A. Drink adequate water daily
• B. Take with food
• C. Avoid alcohol consumption
• D. Store medication in the refrigerator

Correct answer: C

Rationale: The correct information to include in the medication teaching plan for a client receiving metronidazole for Clostridium difficile pseudomembranous colitis is to avoid alcohol consumption. Metronidazole can cause a disulfiram-like reaction when combined with alcohol, leading to symptoms such as nausea, vomiting, flushing, and headache. Therefore, it is crucial for the client to abstain from alcohol while taking this medication to prevent adverse effects and ensure treatment effectiveness. Choices A, B, and D are incorrect. Drinking adequate water daily is a general health recommendation but not specific to metronidazole use. Taking with food is not necessary for metronidazole, and in fact, it is recommended to be taken on an empty stomach for better absorption. Storing the medication in the refrigerator is also incorrect, as metronidazole should be stored at room temperature.

4. Escitalopram is prescribed for a 16-year-old adolescent client who is clinically depressed. Five days later, the parent tells the practical nurse (PN) that the drug is not working because their child is not feeling any better. Which explanation should the PN provide?

• A. It takes 1 to 4 weeks for antidepressant medications to become effective.
• B. The dosage may need to be increased; I will contact your health care provider.
• C. Depression is difficult to treat with drugs alone. Therapy sessions would enhance their effectiveness.
• D. Based on your child's response to this drug, the health care provider is reviewing your medication regimen.

Correct answer: A

Rationale: Antidepressant medications typically require 1 to 4 weeks to reach their full therapeutic effect. It is crucial to educate the family that during the initial week of treatment, the child may experience heightened anxiety. Therefore, it is important to wait for the medication to take its full course before assessing its effectiveness.

5. A client with a history of deep vein thrombosis is prescribed warfarin. The nurse should monitor for which potential adverse effect?

• A. Increased risk of bleeding
• B. Decreased risk of bleeding
• C. Increased risk of infection
• D. Decreased risk of infection

Correct answer: A

Rationale: The correct answer is A: Increased risk of bleeding. Warfarin is an anticoagulant medication that works by prolonging the time it takes for blood to clot. Therefore, a potential adverse effect of warfarin is an increased risk of bleeding. It is crucial for the nurse to monitor the client for signs of bleeding, such as easy bruising, prolonged bleeding from cuts, nosebleeds, or blood in the urine or stool. Monitoring for these signs is essential to prevent serious complications associated with excessive bleeding. Choices B, C, and D are incorrect because warfarin does not decrease the risk of bleeding, increase the risk of infection, or decrease the risk of infection. The primary concern with warfarin therapy is the potential for bleeding complications, so close monitoring for signs of bleeding is essential.
