Correct Answer: A

Rationale: In a client with pneumonia, assessing breath sounds is crucial as it provides immediate information about the client's respiratory status. Changes in breath sounds could indicate complications like fluid accumulation or worsening pneumonia. While the client's history of smoking (Choice B), current medication list (Choice C), and family history of respiratory illness (Choice D) are important factors to consider, they are not as urgent or directly related to the client's immediate condition as assessing breath sounds.

Correct Answer: D

Rationale: In this scenario, the priority is to ensure the client has a clear airway to facilitate breathing. After verifying unresponsiveness and calling for help, the nurse should open the client's airway to aid in maintaining ventilation. Checking the carotid pulse (Choice A) may be important but comes after ensuring a clear airway. Delivering abdominal thrusts (Choice B) is indicated for choking, not for an unresponsive client. Giving rescue breaths (Choice C) is also important but only after the airway has been established.

Correct Answer: A

Rationale: In a client with a history of asthma experiencing difficulty breathing and wheezing, the priority nursing action is to administer a bronchodilator. This intervention helps relieve bronchospasm and improve the client's breathing. Obtaining a peak flow reading can provide additional information but is not the immediate priority in this situation. Providing supplemental oxygen may be needed but addressing the bronchospasm with a bronchodilator takes precedence. Assessing the client's respiratory rate is important but not as urgent as administering a bronchodilator to address the breathing difficulty.

Correct Answer: D

Rationale: The correct answer is 'Hernias.' Abdominal distention with a midline protrusion, taut skin, and no involvement of the flanks is characteristic of hernias. Hernias are caused by a weakness in the abdominal wall, allowing organs or tissues to protrude through. Fluid accumulation (ascites) typically presents with a more generalized distention, while fat accumulation may cause more diffuse distension rather than a focal midline protrusion. Flatus, or gas, would not typically present with a visible midline protrusion and taut skin like hernias.

Correct Answer: D

Rationale: The correct answer is D. Removing the mobile when the baby starts to push up prevents choking hazards as infants can reach and grab objects posing a risk of choking. Choice A is unsafe as setting the water heater at 130°F can scald a child. Choice B is incorrect because even when a baby can sit up, they still require close supervision in the bathtub. Choice C is unsafe as current guidelines recommend placing babies on their backs to sleep to reduce the risk of sudden infant death syndrome (SIDS). Therefore, choices A, B, and C are incorrect or unsafe practices for infant care.
