Nursing Elites

1. 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.

2. A client with a history of asthma is experiencing wheezing and shortness of breath. What is the priority nursing intervention?

• A. Administer a bronchodilator as prescribed
• B. Encourage the client to drink fluids
• C. Place the client in an upright position
• D. Assess the client's peak flow rate

Correct answer: A

Rationale: Administering a bronchodilator as prescribed is the priority nursing intervention for a client experiencing wheezing and shortness of breath due to asthma. Bronchodilators help relieve bronchoconstriction, allowing better airflow and improving breathing. Encouraging the client to drink fluids may be beneficial in certain situations, but it is not the priority when the client is in respiratory distress. Placing the client in an upright position, not supine, can facilitate easier breathing by allowing the chest to expand fully. While assessing the client's peak flow rate is important in asthma management, in this acute situation, the priority is to provide immediate relief by administering the bronchodilator.

3. A client with gastroesophageal reflux disease (GERD) is being taught about dietary modifications. What should be emphasized?

• A. Avoiding spicy and fatty foods
• B. Eating small, frequent meals
• C. Avoiding meals before bedtime
• D. All of the above

Correct answer: D

Rationale: In managing GERD, dietary modifications play a significant role. Avoiding spicy and fatty foods helps reduce irritation, while eating small, frequent meals prevents overeating, which can trigger reflux. Avoiding meals before bedtime allows for better digestion and reduces the likelihood of acid reflux during the night. Therefore, all of the options (A, B, and C) are crucial in managing GERD symptoms, making choice D the correct answer.

4. When teaching a client about managing hypertension, what dietary advice should be emphasized?

• A. Reduce sodium intake
• B. Increase potassium intake
• C. Limit alcohol consumption
• D. All of the above

Correct answer: D

Rationale: When managing hypertension, it is crucial to adopt comprehensive dietary changes. This includes reducing sodium intake to help lower blood pressure, increasing potassium intake to counteract the effects of sodium and help regulate blood pressure, and limiting alcohol consumption as excessive alcohol can raise blood pressure. Therefore, emphasizing all the options provided (A, B, and C) is essential in effectively managing hypertension and reducing overall cardiovascular risk. Choices A, B, and C are not individually sufficient as a single dietary modification but collectively work together to support blood pressure management.

5. When caring for a client with a urinary catheter, what is the most important intervention to prevent infection?

• A. Use sterile technique for catheter care
• B. Ensure the catheter bag is below the level of the bladder
• C. Provide perineal care daily
• D. Change the catheter only when necessary

Correct answer: B

Rationale: The most important intervention to prevent infection when caring for a client with a urinary catheter is to ensure that the catheter bag is below the level of the bladder. This positioning helps prevent urine backflow, reducing the risk of infection. While using sterile technique for catheter care (Choice A) is important, ensuring proper drainage by keeping the catheter bag below the bladder is crucial to prevent infection. Providing perineal care daily (Choice C) is essential for hygiene but not directly related to preventing catheter-related infections. Changing the catheter only when necessary (Choice D) is important for maintenance, but correct positioning of the catheter bag is more critical in preventing immediate infection.
