1. The laboratory has just called with the arterial blood gas (ABG) results on four patients. Which result is most important for the nurse to report immediately to the health care provider?

• A. pH 7.34, PaO2 82 mm Hg, PaCO2 40 mm Hg, and O2 sat 97%
• B. pH 7.35, PaO2 85 mm Hg, PaCO2 45 mm Hg, and O2 sat 95%
• C. pH 7.46, PaO2 90 mm Hg, PaCO2 32 mm Hg, and O2 sat 98%
• D. pH 7.31, PaO2 91 mm Hg, PaCO2 50 mm Hg, and O2 sat 96%

Correct answer: D

Rationale: The correct answer is D: pH 7.31, PaO2 91 mm Hg, PaCO2 50 mm Hg, and O2 sat 96%. These ABG results indicate uncompensated respiratory acidosis, a critical condition that requires immediate attention. In respiratory acidosis, there is an excess of carbon dioxide in the blood, leading to a decrease in pH. The other options present normal or near-normal ABG values, indicating adequate oxygenation and ventilation. Therefore, these values would not be as urgent to report compared to the patient with respiratory acidosis in option D.

2. Following assessment of a patient with pneumonia, the nurse identifies a nursing diagnosis of ineffective airway clearance. Which assessment data best supports this diagnosis?

• A. Weak, nonproductive cough effort
• B. Large amounts of greenish sputum
• C. Respiratory rate of 28 breaths/minute
• D. Resting pulse oximetry (SpO2) of 85%

Correct answer: A

Rationale: The correct answer is 'Weak, nonproductive cough effort.' A weak, nonproductive cough indicates that the patient is unable to clear the airway effectively, supporting the nursing diagnosis of ineffective airway clearance. In pneumonia, secretions can obstruct the airway, leading to ineffective clearance. Choices B, C, and D do not directly reflect ineffective airway clearance. Large amounts of greenish sputum (Choice B) may suggest infection or inflammation but do not specifically indicate ineffective airway clearance. The respiratory rate of 28 breaths/minute (Choice C) and a resting pulse oximetry (SpO2) of 85% (Choice D) are more indicative of impaired gas exchange or respiratory distress rather than ineffective airway clearance.

3. A client with asthma has low-pitched wheezes present in the final half of exhalation. One hour later, the client has high-pitched wheezes extending throughout exhalation. This change in assessment indicates to the nurse that the client:

• A. Has increased airway obstruction.
• B. Has improved airway obstruction.
• C. Needs to be suctioned.
• D. Exhibits hyperventilation.

Correct answer: B

Rationale: The change from low-pitched wheezes to high-pitched wheezes indicates a shift from larger to smaller airway obstruction, suggesting increased narrowing of the airways. This change signifies a progression or worsening of the airway obstruction. The absence of evidence of secretions does not support the need for suctioning. Hyperventilation is characterized by rapid and deep breathing, which is not indicated by the information provided in the question.

4. When auscultating the patient's lungs during a shift assessment on a patient admitted in the early phase of heart failure, which finding would the nurse most likely hear?

• A. Continuous rumbling, snoring, or rattling sounds mainly on expiration
• B. Continuous high-pitched musical sounds on inspiration and expiration
• C. Discontinuous, high-pitched sounds of short duration heard on inspiration
• D. A series of long-duration, discontinuous, low-pitched sounds during inspiration

Correct answer: C

Rationale: In the early phase of heart failure, fine crackles are likely to be heard upon auscultation of the lungs. Fine crackles are characterized as discontinuous, high-pitched sounds of short duration heard on inspiration. Rhonchi are continuous rumbling, snoring, or rattling sounds mainly on expiration, which are often associated with airway secretions. Coarse crackles are a series of long-duration, discontinuous, low-pitched sounds during inspiration, typically indicating fluid in the alveoli. Wheezes are continuous high-pitched musical sounds on inspiration and expiration, commonly heard in conditions like asthma or chronic obstructive pulmonary disease (COPD). Therefore, the correct choice is C, as it describes the expected lung sounds in a patient with early heart failure.

5. For a 6-year-old child hospitalized with moderate edema and mild hypertension associated with acute glomerulonephritis (AGN), which one of the following nursing interventions would be appropriate?

• A. Institute seizure precautions
• B. Weigh the child twice per shift
• C. Encourage the child to eat protein-rich foods
• D. Relieve boredom through physical activity

Correct answer: A

Rationale: Institute seizure precautions. The severity of the acute phase of AGN is variable and unpredictable; therefore, a child with edema, hypertension, and gross hematuria may be subject to complications, and anticipatory preparation such as seizure precautions is needed. Weighing the child twice per shift may be necessary for monitoring fluid balance but is not specifically related to the complications of AGN. Encouraging the child to eat protein-rich foods is important for overall nutrition but does not directly address the potential complications of AGN. Relieving boredom through physical activity is beneficial for overall well-being but is not the priority in this situation where seizure precautions are essential.
