Correct Answer: A

Rationale: Paradoxic chest movement is the most concerning finding as it indicates a potential flail chest, which can lead to severe compromise in gas exchange and rapid hypoxemia. This condition requires immediate attention to prevent respiratory distress. Complaint of chest wall pain, a slightly elevated heart rate, and a large bruised area on the chest are important assessment findings but may not immediately threaten gas exchange or respiratory function. Therefore, identifying paradoxic chest movement is critical for prompt intervention and management.

Correct Answer: A

Rationale: To assess for tactile fremitus, the nurse should use the palms of the hands to assess for vibration when the patient repeats a word or phrase such as '99'. After noting absent fremitus, the nurse should then auscultate the lungs to assess for the presence or absence of breath sounds. Absent fremitus may be noted with conditions like pneumothorax or atelectasis. The vibration is increased in conditions such as pneumonia, lung tumors, thick bronchial secretions, and pleural effusion. Encouraging the patient to turn, cough, and deep breathe is an appropriate intervention for atelectasis, but assessing breath sounds takes priority. Fremitus is decreased if the hand is farther from the lung or the lung is hyperinflated (barrel chest). Palpating the anterior chest for fremitus is less effective due to the presence of large muscles and breast tissue, making auscultation a more appropriate next step.

Correct Answer: C

Rationale: In acute bronchitis, which is often viral, cough suppressants can help manage the symptoms of a nonproductive cough. Antibiotics are not typically used in acute bronchitis unless there are systemic symptoms indicating a bacterial infection. Limiting oral fluid intake is not recommended; in fact, maintaining adequate hydration is important. Safety concerns with home oxygen therapy may not be directly relevant to the management of acute bronchitis.

Correct Answer: A

Rationale: The correct teaching for the child and parents when a child is prescribed baclofen via an intrathecal pump is to not let the prescription run out. Abrupt discontinuation of intrathecal baclofen can lead to severe effects like high fever, altered mental status, and rebound spasticity and muscle rigidity. It is crucial for the parents to ensure there is always an adequate supply of this medication to prevent these adverse effects. Choices B and D are incorrect because gingival hyperplasia and hirsutism are side effects associated with phenytoin (Dilantin), not baclofen. Choice C is incorrect as serum drug levels are not typically monitored for intrathecal medications.

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.
