1. 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?

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.

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

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.

3. A nurse in a community health center is assessing the results of the purified protein derivative (PPD) testing she performed to screen for tuberculosis (TB). She interprets which of the following results as positive for a 6-year-old client with no risk factors for TB?

Correct answer: D

Rationale: The correct answer is D: 15-mm induration. In PPD testing, an induration (hardened raised area) of 15 mm or more is considered positive for TB in individuals with no risk factors. Choices A, B, and C are incorrect because an erythema of 4 mm, induration of 5 mm, or wheal of 10 mm are not indicative of a positive TB test result in a low-risk individual. Therefore, the interpretation of a 15-mm induration would lead the nurse to consider the test positive for TB in this case.

4. 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?

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.

5. A client with peripheral arterial disease (PAD) is experiencing muscle pain or cramping during physical activity that resolves with rest. Which of the following symptoms is typically the initial reason clients with PAD seek medical attention?

Correct answer: A

Rationale: The correct answer is Intermittent claudication. Intermittent claudication, which manifests as muscle pain or cramping during physical activity that improves with rest, is typically the initial reason clients with PAD seek medical attention. Dependent rubor, rest pain, and foot ulcers are more advanced symptoms of PAD and are not usually the initial reasons for seeking medical care.
