Nursing Elites

1. A healthcare provider is reviewing a client's medication list during a routine visit. Which action is most important to ensure medication safety?

• A. Ask the client about any allergies to medications
• B. Review the purposes of each medication
• C. Check for potential drug interactions
• D. All of the above

Correct answer: D

Rationale: A comprehensive review of allergies, medication purposes, and potential interactions is crucial for ensuring medication safety. Asking about allergies helps prevent adverse reactions, reviewing medication purposes ensures the correct use of each drug, and checking for potential drug interactions reduces the risk of harmful effects when medications interact. Choosing 'All of the above' is the correct answer because all three actions are essential steps to enhance medication safety. Options A, B, and C individually play vital roles in promoting medication safety, making option D the most appropriate choice.

2. A client is scheduled for an abdominal ultrasound in the morning and has been instructed to fast overnight. The client asks the nurse why fasting is necessary. What is the best response?

• A. It helps reduce the production of intestinal gases.
• B. It ensures clearer imaging by emptying the stomach.
• C. It prevents the risk of aspiration during the procedure.
• D. It is a standard procedure for all surgical interventions.

Correct answer: B

Rationale: The correct answer is B: 'It ensures clearer imaging by emptying the stomach.' Fasting before an abdominal ultrasound is essential to empty the stomach, allowing for better visualization of the abdominal organs. This improves the quality of the imaging and enhances diagnostic accuracy. Choices A, C, and D are incorrect because reducing intestinal gases, preventing aspiration, and being a standard procedure for surgical interventions are not the primary reasons for fasting before an abdominal ultrasound.

3. A client who fell 20 feet from the roof of his home has multiple injuries, including a right pneumothorax. Chest tubes were inserted in the emergency department prior to his transfer to the intensive care unit (ICU). The nurse observes that the suction control chamber is bubbling at the -10 cm H20 mark, with fluctuation in the water seal, and over the past hour, 75 mL of bright red blood is measured in the collection chamber. Which intervention should the nurse implement?

• A. Increase wall suction to eliminate fluctuation in the water seal.
• B. Give blood from the collection chamber as autotransfusion.
• C. Add sterile water to the suction control chamber.
• D. Manipulate blood in tubing to drain into chamber.

Correct answer: C

Rationale: The correct intervention for the nurse to implement is to add sterile water to the suction control chamber. This action helps maintain the proper functioning of the chest tube system by regulating the negative pressure. Increasing wall suction is not recommended as it could lead to excessive negative pressure. Giving blood from the collection chamber as autotransfusion is inappropriate and poses a risk of complications such as air embolism. Manipulating blood in the tubing is also unsafe as it could introduce air into the system, increasing the risk of complications for the client.

4. A client with a diagnosis of rheumatoid arthritis is prescribed methotrexate. What is the primary action of this medication?

• A. Increases joint lubrication
• B. Reduces inflammation by suppressing the immune system
• C. Enhances bone density
• D. Stimulates cartilage regeneration

Correct answer: B

Rationale: The correct answer is B: Methotrexate is an immunosuppressant that works by suppressing the immune system, thereby reducing inflammation in rheumatoid arthritis. Methotrexate does not directly increase joint lubrication (Choice A) as its primary action is on the immune system. Choices C and D are incorrect since methotrexate does not enhance bone density or stimulate cartilage regeneration. It is crucial for healthcare providers to understand the mechanism of action of medications to provide safe and effective care to patients.

5. The practical nurse is preparing to administer a prescription for cefazolin (Kefzol) 600 mg IM every six hours. The available vial is labeled, 'Cefazolin (Kefzol) 1 gram,' and the instructions for reconstitution state, 'For IM use add 2 ml sterile water for injection. Total volume after reconstitution = 2.5 ml.' When reconstituted, how many milligrams are in each milliliter of solution?

• A. 400 mg/mL
• B. 500 mg/mL
• C. 450 mg/mL
• D. 350 mg/mL

Correct answer: A

Rationale: After reconstitution, the concentration of cefazolin solution is calculated by dividing the total amount of drug (600 mg) by the total volume after reconstitution (2.5 mL). This gives 600 mg / 2.5 mL = 240 mg/mL. However, the question asks for the concentration in each milliliter of solution after reconstitution, so we need to consider the final volume of 2.5 mL. Therefore, 240 mg/mL * 2.5 mL = 600 mg, which means each milliliter contains 240 mg of cefazolin. Therefore, after reconstitution, there are 400 mg of cefazolin in each milliliter of solution. Choices B, C, and D are incorrect as they do not accurately reflect the concentration after reconstitution.
