Nursing Elites

1. A healthcare professional is reviewing the medical record of a client scheduled for a CT scan with contrast media. The healthcare professional should identify which of the following findings as a contraindication to the procedure?

• A. White blood cell count of 6,000/mm³
• B. Urine specific gravity of 1.025
• C. History of asthma
• D. History of allergy to shellfish

Correct answer: D

Rationale: The correct answer is D, a history of allergy to shellfish. A known allergy to shellfish is a contraindication for the use of contrast media in a CT scan due to the potential risk of an allergic reaction, which could be severe and life-threatening. Choices A, B, and C are not contraindications to the procedure. A normal white blood cell count, urine specific gravity within the normal range, and a history of asthma do not typically interfere with the administration of contrast media for a CT scan.

2. A client with diabetes mellitus is being taught by a nurse on managing hypoglycemia. Which of the following instructions should the nurse include?

• A. Avoid consuming carbohydrate-rich foods.
• B. Consume 15 grams of a fast-acting carbohydrate.
• C. Drink a glass of water to raise blood glucose levels.
• D. Eat a snack before exercising to prevent hypoglycemia.

Correct answer: B

Rationale: The correct answer is B: Consume 15 grams of a fast-acting carbohydrate. Consuming 15 grams of a fast-acting carbohydrate, such as glucose tablets or juice, helps raise blood glucose levels quickly in cases of hypoglycemia. Choice A is incorrect because avoiding carbohydrate-rich foods during hypoglycemia can worsen the condition. Choice C is incorrect as drinking water does not effectively raise blood glucose levels. Choice D is incorrect as eating a snack before exercising is more related to preventing exercise-induced hypoglycemia, not managing hypoglycemia.

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

• A. Take this medication at bedtime to prevent dizziness.
• B. Increase your intake of potassium-rich foods.
• C. Take this medication with food to prevent gastrointestinal upset.
• D. This medication can increase your blood pressure.

Correct answer: B

Rationale: The correct instruction that the nurse should include for a client prescribed hydrochlorothiazide is to increase their intake of potassium-rich foods. Hydrochlorothiazide is a diuretic that can lead to potassium depletion, so increasing potassium-rich foods helps prevent hypokalemia. Option A is incorrect because hydrochlorothiazide is usually taken in the morning to prevent diuresis at night. Option C is not necessary as hydrochlorothiazide can be taken with or without food. Option D is incorrect because hydrochlorothiazide is used to lower blood pressure, not increase it.

4. A client has had vomiting and diarrhea for the past 3 days. Which of the following findings indicates the client is experiencing fluid volume deficit?

• A. Jugular vein distention
• B. Bradycardia
• C. Increased respiratory rate
• D. Bounding pulses

Correct answer: C

Rationale: An increased respiratory rate is a sign of fluid volume deficit as the body attempts to compensate for decreased blood volume. Jugular vein distention, bradycardia, and bounding pulses are not typical findings of fluid volume deficit. Jugular vein distention is more commonly associated with fluid volume overload, bradycardia can be a sign of fluid volume excess or other issues, and bounding pulses are not typically seen in fluid volume deficit.

5. How should a healthcare professional administer a subcutaneous injection?

• A. Insert the needle at a 45-degree angle
• B. Insert the needle at a 90-degree angle
• C. Use a Z-track method
• D. Insert the needle at a 15-degree angle

Correct answer: A

Rationale: The correct technique for administering subcutaneous injections is to insert the needle at a 45-degree angle. This angle ensures that the medication is delivered into the subcutaneous tissue, which is located just below the skin. Inserting the needle at a 90-degree angle is more appropriate for intramuscular injections, while using a Z-track method is specific to intramuscular injections to prevent leakage of medication into the subcutaneous tissue. Inserting the needle at a 15-degree angle would not reach the subcutaneous tissue effectively.
