Nursing Elites

1. A client receiving chemotherapy reports nausea and vomiting. Which of the following medications should the nurse anticipate administering?

• A. Ondansetron
• B. Metoclopramide
• C. Promethazine
• D. Lorazepam

Correct answer: A

Rationale: The correct answer is A: Ondansetron. Ondansetron is a commonly used antiemetic for managing nausea and vomiting in clients undergoing chemotherapy. It works by blocking serotonin to reduce these symptoms effectively. Metoclopramide (choice B) is another antiemetic but is more commonly used for gastric motility disorders. Promethazine (choice C) is an antihistamine with antiemetic properties, but ondansetron is often preferred for chemotherapy-induced nausea and vomiting due to its efficacy and fewer side effects. Lorazepam (choice D) is a benzodiazepine used for anxiety and insomnia, not typically for managing nausea and vomiting in this context.

2. What is the therapeutic use of Phenytoin?

• A. Replacement in hypothyroidism to restore normal hormonal balance
• B. Diminished accumulation of acid in the gastric lumen with lessened gastroesophageal reflux
• C. Diminished seizure activity, termination of ventricular arrhythmias
• D. Prevention of thrombus formation, prevention of extension of existing thrombi

Correct answer: C

Rationale: Phenytoin is primarily used to diminish seizure activity and is effective in terminating ventricular arrhythmias. It works by stabilizing neuronal membranes, reducing repetitive neuronal firing, and limiting the spread of seizure activity in the brain. While phenytoin does not have a direct role in preventing thrombus formation or extending existing thrombi, it is crucial in managing seizures and certain arrhythmias.

3. When caring for a client prescribed Lithium, which laboratory value should the nurse monitor to assess for potential toxicity?

• A. Serum sodium
• B. Serum lithium
• C. Serum potassium
• D. Serum calcium

Correct answer: B

Rationale: The nurse should monitor the client's serum lithium levels to ensure they are within the therapeutic range and to assess for potential toxicity. Monitoring serum lithium levels is crucial because lithium has a narrow therapeutic range, and levels outside this range can lead to toxicity, which can be life-threatening. Therefore, regular monitoring is essential to prevent adverse effects and ensure the medication's effectiveness.

4. When educating a client who has a new prescription for Hydrochlorothiazide, which of the following statements should the nurse include?

• A. Take this medication in the morning.
• B. You may need to increase your intake of potassium.
• C. This medication may cause drowsiness.
• D. Avoid consuming grapefruit.

Correct answer: B

Rationale: The correct statement to include when educating a client with a new prescription for Hydrochlorothiazide is that they may need to increase their intake of potassium. Hydrochlorothiazide is a thiazide diuretic that can lead to potassium loss. Monitoring potassium levels and increasing potassium intake if necessary can help prevent complications associated with hypokalemia. Option A is not directly related to the medication's specific instructions. Option C is incorrect as Hydrochlorothiazide typically does not cause drowsiness. Option D is unrelated, as there is no interaction between Hydrochlorothiazide and grapefruit.

5. A client has a new prescription for a Fentanyl transdermal patch. Which of the following instructions should the nurse include?

• A. Apply the patch to a non-hairy area.
• B. Change the patch every 72 hours.
• C. Avoid exposure to heat sources.
• D. Do not cut the patch to adjust the dosage.

Correct answer: C

Rationale: The correct instruction the nurse should include for a client using a Fentanyl transdermal patch is to avoid exposure to heat sources. Heat can increase the absorption of the medication, potentially causing an overdose. Instructing the client to avoid heat sources is crucial to ensure their safety and the effectiveness of the medication. Choices A, B, and D are incorrect because applying the patch to a non-hairy area, changing it every 72 hours, and not cutting the patch are general guidelines for using transdermal patches but do not specifically address the unique risks associated with Fentanyl patches.
