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. When assisting a client to obtain a sputum specimen, the nurse observes the client cough and spit a large amount of frothy saliva in the specimen collection cup. What action should the nurse implement next?

• A. Advise the client that suctioning will be used to obtain another specimen
• B. Re-instruct the client in coughing techniques to obtain another specimen
• C. Provide the client a glass of water and mouthwash to rinse the mouth
• D. Label the container and place the container in a biohazard transport bag

Correct answer: C

Rationale: After observing the client cough and produce frothy saliva in the collection cup, the nurse should provide the client with a glass of water and mouthwash to rinse the mouth. This action helps clear the mouth of contaminants, ensuring a more accurate sputum specimen for diagnostic testing. Option A is incorrect because suctioning is not the appropriate next step in this situation. Option B is unnecessary as re-instructing the client in coughing techniques may not address the immediate issue of contaminated saliva in the specimen. Option D is premature since labeling and transporting the container should only be done after obtaining a valid specimen.

3. A client with a diagnosis of heart failure is receiving furosemide (Lasix). Which electrolyte imbalance should the nurse monitor for?

• A. Hyperkalemia.
• B. Hyponatremia.
• C. Hypocalcemia.
• D. Hypokalemia.

Correct answer: D

Rationale: The correct answer is D: Hypokalemia. Furosemide is a loop diuretic that can cause potassium loss, leading to hypokalemia. Therefore, the nurse should monitor the client for low potassium levels. Choice A, Hyperkalemia, is incorrect as furosemide does not typically cause high potassium levels. Choice B, Hyponatremia, is incorrect as furosemide primarily affects potassium levels, not sodium. Choice C, Hypocalcemia, is incorrect as furosemide does not directly impact calcium levels.

4. A client with a history of hypertension is admitted to the hospital for a suspected myocardial infarction. Which of the following is the priority nursing action?

• A. Administer oxygen as prescribed
• B. Perform an ECG
• C. Obtain a detailed health history
• D. Monitor vital signs regularly

Correct answer: B

Rationale: The priority nursing action in this scenario is to perform an ECG. An ECG is crucial in confirming myocardial infarction promptly and guiding immediate treatment decisions. Administering oxygen as prescribed is important but not the priority over confirming the diagnosis. Obtaining a detailed health history is relevant but does not take precedence over immediate diagnostic confirmation. While monitoring vital signs regularly is essential, performing an ECG is the priority action in this scenario to guide timely management.

5. A client with a diagnosis of pneumonia is experiencing difficulty expectorating thick secretions. What intervention should the nurse implement to assist the client?

• A. Administer antibiotics as prescribed.
• B. Encourage increased fluid intake.
• C. Perform chest physiotherapy.
• D. Provide humidified oxygen.

Correct answer: B

Rationale: Encouraging increased fluid intake is the appropriate intervention to assist the client with pneumonia who is having difficulty expectorating thick secretions. Adequate hydration helps to thin the secretions, making them easier to cough up. Administering antibiotics (Choice A) is important for treating the infection itself but does not directly address the thick secretions. Chest physiotherapy (Choice C) may be beneficial in some cases but is not the initial intervention for thick secretions. Providing humidified oxygen (Choice D) can help with oxygenation but does not directly address the problem of thick secretions.
