Nursing Elites

1. A client's arterial blood gas results show a pH of 7.3 and a PaCO2 of 50 mm Hg. The client is experiencing which of the following acid-base imbalances?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: C

Rationale: In respiratory acidosis, there is an excess of carbon dioxide (PaCO2 > 45 mm Hg) leading to a decrease in pH (<7.35). The given values of a pH of 7.3 and PaCO2 of 50 mm Hg indicate respiratory acidosis. Metabolic acidosis involves a primary decrease in bicarbonate levels with a compensatory decrease in PaCO2 to maintain balance. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. Respiratory alkalosis is marked by low PaCO2 and increased pH levels.

2. A client is prescribed nicotine replacement therapy. Which statement should the nurse include in this client's teaching?

• A. Smoking while taking this medication will increase your risk of a stroke.
• B. Make a list of reasons why smoking is a bad habit.
• C. Stopping this medication suddenly increases your risk for a heart attack.
• D. Rise slowly when getting out of bed in the morning.

Correct answer: A

Rationale: When a client is prescribed nicotine replacement therapy, it is crucial to emphasize that smoking while using this therapy can increase the risk of a stroke. Smoking while on nicotine replacement therapy can lead to excessive nicotine levels in the body, elevating cardiovascular risks. Therefore, the nurse should educate the client on the importance of avoiding smoking while utilizing this medication. Choices B, C, and D are not relevant to the specific teaching required for a client on nicotine replacement therapy.

3. A client with tuberculosis is starting medication therapy with isoniazid, rifampin, and pyrazinamide. Which of the following instructions should the nurse include?

• A. Take isoniazid with an antacid.
• B. Provide a sputum specimen every 2 weeks to the clinic for testing.
• C. Expect your sputum cultures to be negative after 6 months of therapy.
• D. Drink at least 8 ounces of water when you take the pyrazinamide tablet.

Correct answer: D

Rationale: Pyrazinamide can cause gastrointestinal upset and is best taken with a full glass of water to minimize irritation to the stomach lining. This instruction helps reduce the risk of adverse effects associated with pyrazinamide. Options A and C are not directly related to the medication regimen for tuberculosis. While sputum testing is important, the frequency mentioned in option B is not required every two weeks.

4. During an assessment, an older adult client's son reports that the client has been sick with a respiratory illness for the past 6 days. Which of the following assessment findings is a manifestation of pneumonia in the older adult client?

• A. Bradycardia
• B. Night sweats
• C. Confusion
• D. Narrowed pulse pressure

Correct answer: C

Rationale: Confusion is a common manifestation of pneumonia in older adults. It can result from inadequate oxygenation to the brain due to respiratory compromise. Bradycardia, night sweats, and narrowed pulse pressure are not typically specific findings associated with pneumonia and should be further assessed or monitored, but confusion is a key indicator that warrants immediate attention.

5. A client with hypertension is being taught about lifestyle modifications. Which statement by the client indicates a need for further teaching?

• A. I will reduce my sodium intake to help control my blood pressure.
• B. I need to start walking at least 30 minutes most days of the week.
• C. I can continue drinking alcohol as long as it is not in excess.
• D. I will check my blood pressure regularly at home.

Correct answer: C

Rationale: In hypertension management, it is crucial for clients to limit or avoid alcohol consumption, not just refrain from excess. Alcohol can raise blood pressure and interfere with the effectiveness of antihypertensive medications, making it a key lifestyle modification for individuals with hypertension.
