Correct Answer: A

Rationale: In a client with pleural effusion, decreased breath sounds on the affected side are common due to the presence of fluid in the pleural space. Hyperresonance is not expected; dullness on percussion is more likely. Tactile fremitus is typically decreased, not increased, in pleural effusion cases. Tracheal deviation away from the affected side, not toward it, can be seen with large effusions.

Correct Answer: D

Rationale: When educating a client with COPD about nutrition, it is important to consider factors that can impact breathing and digestion. Avoiding drinking fluids just before and during meals can help prevent bloating, which may impede breathing. Resting before meals if experiencing dyspnea can aid in reducing respiratory effort during eating. Having about six small meals a day can help prevent overeating and decrease the feeling of fullness, promoting easier breathing. However, it is crucial to be cautious with high-fiber foods as they can produce gas, leading to abdominal bloating and increased shortness of breath. Clients with COPD should focus on increasing calorie and protein intake to prevent malnourishment. It is advisable not to increase carbohydrate intake as this can elevate carbon dioxide production and exacerbate breathing difficulties.

Correct Answer: B

Rationale: A low platelet count, as seen in choice B, is concerning as it could indicate heparin-induced thrombocytopenia, a serious side effect of heparin therapy. Heparin-induced thrombocytopenia can lead to an increased risk of blood clotting, potentially causing severe complications. Monitoring platelet counts is crucial during heparin therapy to promptly identify and manage this adverse effect.

Correct Answer: A

Rationale: The correct answer is A. Using the peak flow meter every morning is crucial for monitoring asthma control and making timely treatment adjustments. While using the meter when feeling short of breath or before using an inhaler can also be beneficial, the daily morning routine helps in consistent management of asthma symptoms.

Correct Answer: B

Rationale: To ensure effective use of albuterol via a metered-dose inhaler, the nurse should have the client hold their breath for 10 seconds after inhaling the medication. This action allows the medication to reach deeper into the airways. Inhaling slowly and deeply, not quickly, is recommended for optimal drug delivery. Exhaling immediately after inhaling the medication would expel it before it can take effect. It's essential for the client to follow the prescribed regimen of medication usage, not just using the inhaler when symptoms are present.
