1. A client with asthma develops respiratory acidosis. Based on this diagnosis, what should the nurse expect the client's serum potassium level to be?

• A. normal
• B. elevated
• C. low
• D. unrelated to the pH

Correct answer: B

Rationale: In respiratory acidosis, the body retains CO2, leading to increased hydrogen ion concentration and a drop in blood pH. As pH decreases, serum potassium levels increase due to the movement of potassium out of cells to compensate for the acidosis. Elevated serum potassium levels are expected in respiratory acidosis. Choice A ('normal') is incorrect because potassium levels are expected to be elevated in respiratory acidosis. Choice C ('low') is incorrect as potassium levels rise in this condition. Choice D ('unrelated to the pH') is incorrect as serum potassium levels are directly impacted by changes in pH in respiratory acidosis.

2. After a client with an Automated Internal Cardiac Defibrillator (AICD) is successfully defibrillated for Ventricular Fibrillation (VF), what should the nurse do next?

• A. Go to the client to assess for signs and symptoms of decreased cardiac output.
• B. Call the physician to inform them of the VF episode for medication adjustments.
• C. Call the 'on-call' person in the cath lab to re-charge the ICD in case of a recurrence.
• D. Document the incident on the code report form and follow up regularly.

Correct answer: A

Rationale: After a client is successfully defibrillated, the immediate priority is to assess the client for signs and symptoms of decreased cardiac output, such as altered level of consciousness, chest pain, shortness of breath, or hypotension. This assessment is crucial to determine the effectiveness of the defibrillation and the client's current hemodynamic status. Calling the physician for medication adjustments without assessing the client first could delay essential interventions. Contacting the 'on-call' person in the cath lab to re-charge the ICD is not the initial action needed after successful defibrillation. Documenting the incident is important but should not take precedence over assessing the client's immediate condition.

3. A client had a C5 spinal cord contusion that resulted in quadriplegia. Two days after the injury occurred, the nurse sees his mother crying in the waiting room. The mother asks the nurse whether her son will ever play football again. Which of the following is the best initial response?

• A. "Given time and motivation, your son may regain some function, but I will seek more information from the physician."?
• B. Maintain a calm demeanor and speech pattern while addressing the mother's concerns.
• C. "I'm not sure, but I'll call the physician to discuss this with you promptly."?
• D. "It's not beneficial for your son if you get upset."?

Correct answer: C

Rationale: The best initial response in this situation is to acknowledge the mother's concern, express uncertainty, and offer to obtain more information from the physician. By saying, "I'm not sure, but I'll call the physician to discuss this with you promptly,"? the nurse demonstrates empathy, honesty, and a commitment to providing accurate information. Offering vague reassurance (Choice A) may raise false hopes as outcomes for spinal cord injuries are unpredictable. While maintaining a calm demeanor (Choice B) is important, it does not directly address the mother's immediate need for information. Discouraging the mother from feeling upset (Choice D) is dismissive of her emotions and does not address her question, which is seeking information about her son's prognosis.

4. A 46-year-old has returned from a heart catheterization and wants to get up to start walking 3 hours after the procedure. The nurse should:

• A. Tell the patient to remain with the leg straight for at least another hour and check the chart for activity orders.
• B. Allow the patient to begin limited ambulation with assistance.
• C. Recommend a physical therapy consultation for ambulation.
• D. Tell the patient to remain with the leg straight for another 6 hours and check the chart for activity orders.

Correct answer: A

Rationale: The correct answer is to tell the patient to remain with the leg straight for at least another hour after a heart catheterization before starting ambulation. This period allows for proper healing and reduces the risk of complications such as bleeding or hematoma formation at the catheter insertion site. Starting ambulation too soon can disrupt the healing process and lead to adverse events. Choice B is incorrect because limited ambulation should not be initiated shortly after the procedure as it may increase the risk of complications. Choice C is incorrect as physical therapy consultation is not typically necessary for initial ambulation post-heart catheterization; this can be managed by nursing staff. Choice D is incorrect as keeping the leg straight for 6 hours is excessive and unnecessary, potentially leading to complications such as deep vein thrombosis due to prolonged immobility.

5. When teaching a client about anti-retroviral therapy for human immunodeficiency virus (HIV), the PN should emphasize:

• A. When started, therapy must not be interrupted to prevent viral resistance.
• B. When started, therapy must not be interrupted to prevent opportunistic infection.
• C. Therapy should not be interrupted for one day each month to prevent toxicity.
• D. Therapy should not be interrupted for one week every three months to prevent toxicity.

Correct answer: A

Rationale: When teaching a client about anti-retroviral therapy for HIV, it is crucial to emphasize that therapy must not be interrupted to prevent viral resistance. HIV mutates rapidly, and any interruption can lead to the emergence of resistant strains, compromising treatment effectiveness. Choice B is incorrect because keeping the virus in check with anti-retrovirals helps the client's immune system fight off opportunistic infections. Choices C and D are incorrect because therapy should not be interrupted for any reason. If toxicity occurs, the healthcare provider may adjust the treatment regimen by prescribing alternative anti-retroviral drugs.
