Nursing Elites

1. A nurse is caring for a client who is receiving IV diltiazem for atrial fibrillation. Which of the following findings is a contraindication to the administration of diltiazem?

• A. Hypotension
• B. Tachycardia
• C. Decreased level of consciousness
• D. History of diuretic use

Correct answer: A

Rationale: The correct answer is A: Hypotension. Diltiazem can cause further lowering of blood pressure, so it should not be administered if the client is already hypotensive. Monitoring blood pressure is crucial before giving diltiazem. Choice B, tachycardia, is not a contraindication for diltiazem use; in fact, diltiazem is used to slow down the heart rate. Choice C, decreased level of consciousness, may indicate other issues but is not a direct contraindication for diltiazem. Choice D, history of diuretic use, is not a contraindication by itself; however, caution should be exercised when diltiazem is given with diuretics due to potential interactions.

2. A nurse is assessing a client who has diabetic ketoacidosis (DKA). Which of the following laboratory findings should the nurse expect?

• A. Blood glucose 120 mg/dL
• B. pH 7.32
• C. HCO3 25 mEq/L
• D. PaCO2 48 mm Hg

Correct answer: B

Rationale: The correct answer is B. A pH of 7.32 indicates metabolic acidosis, which is a hallmark of diabetic ketoacidosis (DKA). In DKA, blood glucose levels are typically elevated, bicarbonate levels are often low, and there is a compensatory respiratory response leading to a decrease in PaCO2. Option A is incorrect because a blood glucose level of 120 mg/dL is within the normal range and not indicative of DKA. Option C is incorrect because an HCO3 level of 25 mEq/L is not typically seen in DKA where bicarbonate levels are usually lower. Option D is incorrect because a PaCO2 of 48 mm Hg would not be expected in DKA; it would typically be lower due to compensatory respiratory alkalosis.

3. A nurse is providing discharge instructions for a client after surgery. Which of the following should be included?

• A. Resume normal activities immediately
• B. Monitor for signs of infection
• C. Avoid all physical activity for 1 month
• D. Take pain medications only as needed

Correct answer: B

Rationale: The correct answer is B: 'Monitor for signs of infection.' After surgery, it is essential for clients to watch for signs of infection, such as increased redness, swelling, or drainage at the incision site. Choice A is incorrect because resuming normal activities immediately after surgery can be harmful. Choice C is incorrect as complete avoidance of physical activity for a month is typically not necessary and can lead to complications like blood clots. Choice D is incorrect as taking pain medications only as needed may not provide adequate pain management post-surgery.

4. A healthcare professional is teaching a client about the use of methotrexate. Which of the following should be included?

• A. It is a pain reliever
• B. Monitor for signs of infection
• C. It can be taken without food
• D. It is safe to use during pregnancy

Correct answer: B

Rationale: The correct answer is B: 'Monitor for signs of infection.' Methotrexate can suppress the immune system, making the client more susceptible to infections. Educating the client to monitor for signs of infection is crucial for early detection and management. Choice A is incorrect because methotrexate is not a pain reliever; it is commonly used to treat conditions like cancer, rheumatoid arthritis, and psoriasis. Choice C is incorrect because methotrexate is usually recommended to be taken with food to reduce gastrointestinal side effects. Choice D is incorrect because methotrexate is known to be harmful during pregnancy and should not be used by pregnant individuals as it can cause birth defects.

5. A client has been prescribed vasopressin for the treatment of diabetes insipidus. What is the expected pharmacological action of this medication?

• A. To stimulate the pancreas to secrete insulin
• B. To slow the absorption of glucose in the intestine
• C. To increase reabsorption of water in the renal tubules
• D. To increase blood pressure

Correct answer: C

Rationale: The correct answer is C: To increase reabsorption of water in the renal tubules. Vasopressin mimics the action of antidiuretic hormone (ADH) by increasing the reabsorption of water in the renal tubules. This leads to decreased urine output, helping to manage symptoms of diabetes insipidus, which is characterized by excessive thirst and urination. Choices A, B, and D are incorrect. Vasopressin does not stimulate the pancreas to secrete insulin, slow the absorption of glucose in the intestine, or directly increase blood pressure.
