Nursing Elites

1. The healthcare provider prescribes potassium chloride 25 mEq in 500 ml D5W to infuse over 6 hours. The available 20 ml vial of potassium chloride is labeled '10 mEq/5 ml.' How many ml of potassium chloride should the nurse add to the IV fluid?

• A. 12.5
• B. 5
• C. 10
• D. 20

Correct answer: B

Rationale: To prepare 25 mEq of potassium chloride for the infusion, the nurse should add 5 ml of the 10 mEq/5 ml solution. This concentration provides the required amount of potassium chloride without exceeding the needed volume. Choice A would result in 12.5 mEq, which exceeds the prescribed amount. Choices C and D are incorrect as they do not align with the correct calculation based on the vial concentration.

2. A client with a large pleural effusion undergoes a thoracentesis. Following the procedure, which assessment finding warrants immediate intervention by the nurse?

• A. The client has asymmetrical chest wall expansion
• B. The client complains of pain at the insertion site
• C. The client's chest x-ray indicates decreased pleural effusion
• D. The client's arterial blood gases show pH 7.35, PaO2 85, PaCO2 35, HCO3 26

Correct answer: A

Rationale: Asymmetrical chest wall expansion is a critical finding post-thoracentesis as it may suggest a pneumothorax, requiring immediate intervention to prevent further complications. The other options, such as pain at the insertion site (Choice B), decreased pleural effusion on chest x-ray (Choice C), and normal arterial blood gases within acceptable ranges (Choice D) do not indicate an immediate need for intervention like asymmetrical chest wall expansion does.

3. A male client with angina pectoris is being discharged from the hospital. What instructions should the nurse plan to include in the discharge teaching?

• A. Engage in physical exercise before eating to help decrease cholesterol levels.
• B. Avoid walking briskly in cold weather to prevent a decrease in cardiac output.
• C. Keep nitroglycerin in a light-colored plastic bottle and readily available.
• D. Avoid all isometric exercises, but walk regularly.

Correct answer: C

Rationale: The correct answer is to keep nitroglycerin in a light-colored container and readily available. Nitroglycerin should be protected from light to maintain its effectiveness. Option A is incorrect because physical exercise immediately before eating can trigger angina. Option B is incorrect as cold weather can exacerbate angina symptoms. Option D is incorrect as isometric exercises can increase the workload on the heart, which is not recommended for individuals with angina.

4. When admitting a client diagnosed with active tuberculosis to isolation, which infection control measures should the nurse implement?

• A. Negative pressure environment
• B. Contact precautions
• C. Droplet precautions
• D. Protective environment

Correct answer: A

Rationale: The correct answer is A: Negative pressure environment. Tuberculosis is transmitted through airborne particles, so a negative pressure room is essential to prevent the spread of the bacteria. Choice B, contact precautions, are used for infections spread by direct or indirect contact, not for tuberculosis. Choice C, droplet precautions, are for infections transmitted through respiratory droplets, not airborne particles like tuberculosis. Choice D, protective environment, is used for protecting immunocompromised patients from outside pathogens, not for preventing the spread of tuberculosis.

5. A 46-year-old male client who had a myocardial infarction 24 hours ago comes to the nurse’s station fully dressed and wanting to go home. He tells the nurse that he is feeling much better at this time. Based on this behavior, which nursing problem should the nurse formulate?

• A. Anxiety related to treatment plan
• B. Deficient knowledge of lifestyle changes
• C. Ineffective coping related to denial
• D. Decisional conflict due to stress

Correct answer: C

Rationale: The correct answer is C: 'Ineffective coping related to denial.' The client's behavior of wanting to go home and feeling much better shortly after a myocardial infarction indicates denial of the severity of his condition. This denial can lead to ineffective coping mechanisms, hindering his recovery and treatment. Choices A, B, and D are incorrect because the client's behavior is not primarily driven by anxiety about the treatment plan, deficient knowledge of lifestyle changes, or decisional conflict due to stress, but rather by denial and ineffective coping mechanisms.
