Correct Answer: D

Rationale: The use of accessory muscles is the most concerning finding in a client with COPD. It indicates increased work of breathing and may signal respiratory distress, requiring immediate attention. Barrel chest is a common physical characteristic in individuals with COPD due to chronic air trapping and hyperinflation of the lungs but is not as acutely concerning as the use of accessory muscles. Clubbing of the fingers is a late sign of chronic hypoxia and is often seen in conditions with prolonged hypoxemia but is not as acute as the use of accessory muscles. Cough with sputum production is a common symptom in COPD due to excess mucus production but does not indicate immediate respiratory distress as the use of accessory muscles does.

Correct Answer: A

Rationale: The correct answer is to wear a gown when caring for the client. Shigellosis is highly contagious, and contact precautions are essential to prevent the spread of infection. Wearing gloves alone may not provide adequate protection as the client's diarrhea can contain infectious pathogens that can easily spread. Standard precautions include hand hygiene, but specific precautions for shigellosis require wearing a gown to protect against contact with infectious material. Wearing a mask and face shield are not necessary for shigellosis, as the primary mode of transmission is through the fecal-oral route, and these precautions are not indicated for this type of transmission.

Correct Answer: B

Rationale: The correct action in this scenario is to disconnect the electronic blood pressure machine and measure the client's blood pressure manually every 15 minutes. Given that the machine is malfunctioning and providing inconsistent readings, relying on manual measurements ensures accuracy and maintains the quality of care. Notifying the manufacturer (Choice A) may be necessary in the long run, but the immediate concern is the accuracy of the vital signs. Adjusting the machine settings again (Choice C) without resolving the underlying issue would not address the problem. Ignoring the extra readings (Choice D) could lead to incorrect assessment and compromise patient care. Therefore, the best course of action is to disconnect the machine and opt for manual blood pressure measurements until the issue is resolved.

Correct Answer: B

Rationale: The correct action for the nurse when assessing the respiratory system for complications of immobility is to auscultate the entire lung region. This approach allows the nurse to identify any diminished breath sounds, crackles, or wheezes that may indicate respiratory issues. Inspecting chest wall movements primarily during the expiratory cycle (Choice A) may not provide a comprehensive assessment of lung sounds. Focusing auscultation on the upper lung fields (Choice C) may miss important findings in the lower lung fields. Assessing the patient at least every 4 hours (Choice D) is important for monitoring overall patient condition but does not specifically address the assessment of respiratory complications related to immobility.

Correct Answer: A

Rationale: Abdominal cramping is a common manifestation of hyponatremia (low sodium levels). When sodium levels drop, it can lead to changes in the body's water balance, affecting cell function and causing symptoms like abdominal cramping. Increased thirst (choice B) is more commonly associated with hypernatremia (high sodium levels) due to the body's attempt to dilute the excess sodium. Elevated blood pressure (choice C) and elevated heart rate (choice D) are not typically direct manifestations of low sodium levels and are more commonly seen in conditions like dehydration or shock.
