Nursing Elites

1. A healthcare professional is preparing to administer heparin 8,000 units subcutaneously every eight hrs. The amount available is heparin injection 10,000 units/mL. How many milliliters should the healthcare professional administer per dose?

• A. 0.7 mL
• B. 0.8 mL
• C. 1.0 mL
• D. 1.2 mL

Correct answer: B

Rationale: Calculation: 8000 units / 10,000 units per mL = 0.8 mL. To correctly administer the prescribed dose of 8000 units, the healthcare professional should draw up 0.8 mL from the 10,000 units/mL vial. Options A, C, and D are incorrect as they do not accurately reflect the calculation based on the available concentration of heparin.

2. A nurse is caring for a client with a stage 2 pressure ulcer. Define the characteristics of the ulcer.

• A. Intact skin with nonblanchable redness (Stage 1)
• B. Full-thickness tissue loss with subQ damage (Stage 3)
• C. Partial-thickness skin loss involving the epidermis and dermis
• D. Full-thickness tissue loss with damage to muscle or bone (Stage 4)

Correct answer: C

Rationale: The correct answer is C. Stage 2 ulcers involve partial-thickness skin loss with visible and superficial damage, which may appear as an abrasion, blister, or shallow crater. Choice A describes a Stage 1 pressure ulcer characterized by intact skin with nonblanchable redness. Choice B describes a Stage 3 pressure ulcer with full-thickness tissue loss and damage to the subcutaneous tissue. Choice D is indicative of a Stage 4 pressure ulcer, involving full-thickness tissue loss with damage extending to muscle or bone.

3. A client has a new prescription for levothyroxine. What should the nurse teach the client?

• A. It should be taken at night
• B. Monitor for symptoms of hypothyroidism
• C. Take it with calcium supplements
• D. Take it on an empty stomach

Correct answer: D

Rationale: The correct answer is to take levothyroxine on an empty stomach. This is because levothyroxine should be taken in the morning on an empty stomach to ensure proper absorption. Option A is incorrect because levothyroxine is usually advised to be taken in the morning. Option B is not the priority teaching point as monitoring for hypothyroidism symptoms is ongoing care. Option C is incorrect as levothyroxine should not be taken with calcium supplements as they can interfere with its absorption.

4. A client with Ménière’s disease is experiencing episodes of vertigo. Which of the following interventions should the nurse include in the plan?

• A. Encourage bed rest
• B. Restrict fluid intake to the morning hours
• C. Administer aspirin
• D. Provide a low sodium diet

Correct answer: D

Rationale: The correct intervention for a client with Ménière’s disease experiencing vertigo is to provide a low sodium diet. Limiting sodium helps to reduce fluid retention, which in turn decreases the manifestations of Ménière’s disease. Encouraging bed rest (Choice A) may be necessary during acute episodes but is not a long-term solution. Restricting fluid intake (Choice B) to the morning hours does not specifically address the underlying issue of fluid retention associated with Ménière’s disease. Administering aspirin (Choice C) is not recommended for Ménière’s disease as it can worsen symptoms.

5. A healthcare professional is verifying nasogastric tube placement by the pH of aspirated gastric fluid. Which of the following pH values provides a good indication of correct tube placement?

• A. 2
• B. 5
• C. 7
• D. 9

Correct answer: A

Rationale: The correct answer is A: '2'. Gastric contents with a pH between 0 and 4 provide a good indication of appropriate tube placement. A pH of 2 is within this range, indicating that the tube is correctly placed in the stomach. Choices B, C, and D are incorrect because a pH of 5, 7, or 9 does not fall within the expected acidic pH range of gastric fluid.
