A client with asthma is being taught about peak flow meter use. Which statement by the client indicates understanding of the teaching?

Correct Answer: A

Rationale: The correct answer is A because using the peak flow meter every morning provides a baseline measurement of lung function when the client is typically stable. This allows for early detection of changes and adjustment of treatment. Choice B is incorrect as waiting until feeling short of breath may be too late. Choice C is incorrect because using the peak flow meter before the inhaler may not provide an accurate measurement. Choice D is incorrect as using the peak flow meter after the inhaler may not reflect the true lung function.

Correct Answer: C

Rationale: The correct answer is C: Dullness on percussion. Pneumonia is characterized by consolidation of lung tissue, causing dullness on percussion due to increased density. Fremitus (A) and tactile fremitus (D) are decreased in conditions like pleural effusion or pneumothorax, not pneumonia. Hyperresonance (B) is associated with conditions like emphysema, not pneumonia. In pneumonia, the affected area is consolidated, leading to dullness on percussion.

Correct Answer: A

Rationale: The correct answer is A because the ability to ambulate without dyspnea indicates effective oxygen therapy. When a client can move without experiencing difficulty breathing, it suggests that the oxygen therapy is adequately supporting their oxygenation needs. In contrast, options B, C, and D do not directly indicate the effectiveness of oxygen therapy. Option B (respiratory rate of 24 breaths per minute) may be within normal range but does not confirm the therapy's efficacy. Option C (oxygen saturation of 92%) is below the desired range of 95-100%, indicating inadequate oxygenation. Option D (productive cough) is unrelated to the assessment of oxygen therapy effectiveness.

Correct Answer: C

Rationale: Step-by-step rationale for choice C (Administer oxygen to maintain saturations greater than 94%): 1. Oxygen is crucial in managing asthma exacerbations to improve oxygen saturation levels and prevent hypoxemia. 2. Decreased pulse oxygen saturation indicates hypoxemia, which can lead to serious complications. 3. Maintaining saturations greater than 94% ensures adequate oxygenation of tissues and organs. 4. Administering oxygen promptly can help alleviate respiratory distress and improve the client's condition. Summary of why other choices are incorrect: - Choice A (Administer albuterol inhaler): While albuterol is a common medication for asthma, oxygen therapy is the priority in this scenario to address hypoxemia. - Choice B (Assess for tracheal deviation): Tracheal deviation is not typically associated with asthma exacerbations and is not the most urgent action needed in this situation. - Choice D (Perform peak expiratory flow measurements): Peak expiratory flow

Correct Answer: B

Rationale: The correct answer is B: Tracheal deviation. Tracheal deviation indicates a tension pneumothorax, a life-threatening emergency that requires immediate intervention to prevent respiratory compromise. The other choices are incorrect because: A: Production of pink sputum may indicate bleeding but does not require immediate intervention unless severe. C: Drainage greater than 70 mL/hr may indicate a potential issue with the chest tube, but it does not require immediate intervention unless accompanied by other symptoms. D: Sudden onset of shortness of breath is concerning but not as immediately life-threatening as tracheal deviation in this context.
