Nursing Elites

1. 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.

2. A healthcare professional is preparing to administer Haloperidol 2 mg PO every 12 hr. The available dosage is haloperidol 1 mg/tablet. How many tablets should the healthcare professional administer?

• A. 1 tablet
• B. 2 tablets
• C. 3 tablets
• D. 4 tablets

Correct answer: B

Rationale: To determine the number of tablets needed, divide the desired dose by the dose per tablet. In this case, (2 mg / 1 mg/tablet) = 2 tablets required to administer the prescribed dose of Haloperidol.

3. A client has a new prescription for Nitroglycerin sublingual tablets. Which of the following instructions should the nurse include in the discharge teaching?

• A. Take one tablet every 15 minutes until pain is relieved.
• B. Take one tablet every 5 minutes, up to three doses.
• C. Take one tablet at bedtime.
• D. Take one tablet on an empty stomach.

Correct answer: B

Rationale: The correct instruction for Nitroglycerin sublingual tablets is to take one tablet at the onset of chest pain, then repeat every 5 minutes for up to three doses. This regimen helps in relieving angina symptoms effectively. Option A of taking one tablet every 15 minutes is too infrequent and may delay symptom relief. Option C of taking one tablet at bedtime is not appropriate as Nitroglycerin is used for immediate relief of angina. Option D of taking one tablet on an empty stomach is irrelevant since Nitroglycerin is not affected by food intake.

4. A client has a new prescription for Captopril. Which of the following instructions should the nurse include?

• A. Take this medication with food.
• B. Avoid foods high in potassium.
• C. Take this medication on an empty stomach.
• D. Increase your intake of sodium-rich foods.

Correct answer: C

Rationale: Captopril should be taken on an empty stomach for better absorption. The client should be instructed to take it 1 hour before or 2 hours after meals to optimize its effectiveness. Taking it with food can reduce its absorption and efficacy.

5. A client asks the nurse how Rituximab works, which the client is receiving to treat Non-Hodgkin's Leukemia. Which of the following should the nurse include?

• A. Blocks hormone receptors
• B. Increases immune response
• C. Binds with specific antigens on tumor cells
• D. Stops DNA replication during cell division

Correct answer: C

Rationale: Rituximab is a monoclonal antibody that binds with specific antigens on B-lymphocytes, leading to the destruction of cancer cells. In the context of Non-Hodgkin's Leukemia, Rituximab targets and destroys cancerous B-lymphocytes, which helps in treating the disease. Choices A, B, and D are incorrect. Rituximab does not block hormone receptors, increase immune response, or stop DNA replication during cell division. The primary mode of action of Rituximab is its binding with specific antigens on tumor cells, specifically B-lymphocytes, to elicit an immune response against cancerous cells.
