Nursing Elites

1. A client is receiving oxygen therapy via a nasal cannula. The nurse should explain that this method of oxygen delivery does which of the following?

• A. Delivers a specific concentration of oxygen constantly
• B. Delivers a high concentration of oxygen
• C. Delivers a low concentration of oxygen
• D. Restricts the client's ability to eat, speak, or drink

Correct answer: A

Rationale: A nasal cannula is a device used for delivering supplemental oxygen to patients. It delivers a specific concentration of oxygen constantly, typically ranging from 1-6 liters per minute. This method is effective for patients who require low to moderate levels of oxygen. Choices B and C are incorrect because a nasal cannula does not deliver a high concentration of oxygen and is not considered a low concentration delivery method. Choice D is incorrect because a nasal cannula does not restrict the client's ability to eat, speak, or drink; it allows them to perform these activities while receiving oxygen therapy.

2. In preparation for the discharge of a client with peripheral arterial disease (PAD), the nurse should include which of the following instructions?

• A. Apply a heating pad on a low setting to help relieve leg pain.
• B. Adjust the thermostat so that the environment is warm.
• C. Wear antiembolic stockings during the day.
• D. Rest with the legs above heart level.

Correct answer: D

Rationale: Resting with the legs above heart level is important for clients with peripheral arterial disease (PAD) to promote better circulation and reduce leg pain. Applying a heating pad on a low setting can actually worsen symptoms by causing burns or increasing blood flow to the area, which is not recommended for PAD. While keeping the environment warm is generally beneficial, it is not a specific instruction for managing PAD. Antiembolic stockings are typically used for preventing blood clots in hospitalized patients and may not be directly related to managing PAD at home.

3. A client who is HIV-positive, has pneumonia and is not responding to antibiotic therapy may have active pulmonary tuberculosis (TB) due to exposure history and symptoms of night sweats and hemoptysis. Which test is the most reliable to confirm the diagnosis of active pulmonary TB?

• A. Chest x-ray
• B. Presence of bronchophony
• C. Mantoux test
• D. Sputum culture for acid-fast bacillus

Correct answer: D

Rationale: The correct answer is D: Sputum culture for acid-fast bacillus. The most reliable test to confirm the diagnosis of active pulmonary TB is the sputum culture for acid-fast bacillus. This test helps identify the presence of Mycobacterium tuberculosis, the causative agent of TB, in the sputum. Chest x-rays can show characteristic findings of TB but are not as reliable as sputum cultures for confirmation. Bronchophony is a test for assessing vocal resonance and is not specific for TB diagnosis. The Mantoux test is a screening test for TB exposure but cannot confirm active disease.

4. When caring for a client with COPD, which intervention should the nurse include in the care plan?

• A. Restrict the client's fluid intake to less than 2 L/day.
• B. Encourage the client to use the upper chest for respiration.
• C. Have the client use the early-morning hours for exercise and activity.
• D. Instruct the client to use pursed-lip breathing.

Correct answer: D

Rationale: The correct answer is to instruct the client to use pursed-lip breathing. This technique helps improve breathing efficiency by keeping the airways open during exhalation and reducing air trapping. Restricting fluid intake to less than 2 L/day is not appropriate for a client with COPD, as they need adequate hydration. Using the upper chest for respiration is incorrect as it promotes shallow breathing, which is not ideal for COPD patients. While exercise is beneficial, early-morning hours may not be the best time for clients with COPD due to increased respiratory distress in the morning.

5. A nurse at a provider's office receives a phone call from a client who reports unrelieved chest pain after taking a nitroglycerin (Nitrostat) tablet 5 minutes ago. Which of the following is an appropriate response by the nurse?

• A. Tell the client to take an aspirin.
• B. Instruct the client to call 911.
• C. Have the client take another nitroglycerin tablet in 15 minutes.
• D. Advise the client to come to the office.

Correct answer: B

Rationale: In this scenario, the client reporting unrelieved chest pain after taking a nitroglycerin tablet could be indicative of a serious cardiac event. Instructing the client to call 911 is the most appropriate response because immediate medical attention is necessary for chest pain that is not relieved by nitroglycerin. Telling the client to take an aspirin (Choice A) may not address the urgency of the situation, and aspirin might not be appropriate depending on the client's medical history. Having the client take another nitroglycerin tablet (Choice C) without relief could lead to overdosage. Advising the client to come to the office (Choice D) is not the best course of action when dealing with a potential cardiac emergency that requires immediate intervention.
