Nursing Elites

1. Oxygen at liters/min per nasal cannula PRN difficult breathing is prescribed for a client with pneumonia. Which nursing intervention is effective in preventing oxygen toxicity?

• A. Avoiding the administration of high levels of oxygen for extended periods.
• B. Administering a sedative at bedtime to slow the client's respiratory rate.
• C. Removing the nasal cannula during the night to prevent oxygen buildup.
• D. Running oxygen through a hydration source prior to administration.

Correct answer: A

Rationale: The correct answer is A: Avoiding the administration of high levels of oxygen for extended periods. Oxygen toxicity can occur when high levels of oxygen are given for a prolonged period. It is important to monitor and adjust the oxygen levels as needed to prevent toxicity. Choice B is incorrect because administering a sedative to slow the respiratory rate does not directly prevent oxygen toxicity. Choice C is incorrect as removing the nasal cannula during the night can compromise the client's oxygenation. Choice D is incorrect as running oxygen through a hydration source does not prevent oxygen toxicity; instead, it may introduce risks associated with the hydration source.

2. When obtaining an admission history for a client who is at 9 weeks gestation, the client states, 'I had a miscarriage 2 years ago.' Which information is most important for the nurse to obtain?

• A. How long was your previous pregnancy?
• B. How long did it take for you to become pregnant after your miscarriage?
• C. Was your miscarriage during the first trimester?
• D. Do you have any children now?

Correct answer: A

Rationale: The correct answer is A. Understanding the duration of the previous pregnancy helps assess the client's obstetric history. Choice B focuses on the time it took to conceive after the miscarriage, which is less relevant at this point. Choice C asks about the timing of the miscarriage rather than the duration of the previous pregnancy. Choice D inquires about the current status of having children, which is not directly related to the client's obstetric history.

3. A 20-year-old male client is diagnosed with Ewing's sarcoma following examination for a knee injury. Which instruction is most important for the nurse to provide the client?

• A. Take analgesics regularly to reduce the pain
• B. Notify the healthcare provider if the swelling worsens
• C. Avoid weight-bearing until the injury heals
• D. Seek treatment for the sarcoma immediately

Correct answer: D

Rationale: The correct answer is to instruct the client to seek treatment for the sarcoma immediately. Ewing's sarcoma is an aggressive cancer, and prompt treatment is crucial for improving prognosis. Option A is incorrect because while pain management is important, addressing the underlying cause (sarcoma) is the priority. Option B is not as critical as seeking treatment for the sarcoma itself. Option C is not the most important instruction as the primary concern is addressing the cancer diagnosis.

4. A client with cirrhosis is taking lactulose (Cephulac). Which finding indicates that the lactulose is having the desired effect?

• A. Two to three soft bowel movements per day
• B. Increased serum ammonia levels
• C. Decreased white blood cell count
• D. Soft, formed stool twice a day

Correct answer: A

Rationale: The correct answer is A: 'Two to three soft bowel movements per day.' Lactulose is prescribed to produce soft, regular bowel movements to reduce ammonia levels in clients with cirrhosis. This helps in preventing hepatic encephalopathy. Option B is incorrect because increased serum ammonia levels would indicate that lactulose is not effectively reducing ammonia levels. Option C is incorrect because lactulose does not directly affect white blood cell counts. Option D is incorrect because soft, formed stools twice a day may not be frequent enough to effectively reduce ammonia levels in clients with cirrhosis.

5. A nurse is planning care for a client who has a new prescription for metoprolol (Lopressor). Which assessment finding should the nurse report to the healthcare provider before administering the medication?

• A. Heart rate of 50 beats per minute
• B. Blood pressure of 90/60 mm Hg
• C. Respiratory rate of 20 breaths per minute
• D. Temperature of 99°F (37.2°C)

Correct answer: A

Rationale: A heart rate of 50 beats per minute is a concerning finding that should be reported before administering metoprolol. Metoprolol is a beta-blocker that can further lower the heart rate, so a heart rate of 50 bpm indicates potential bradycardia, which is a contraindication for administering this medication. Choices B, C, and D are within normal ranges and do not pose immediate concerns related to metoprolol administration.
