Correct Answer: C

Rationale: The correct answer is C. Use of accessory muscles is the most concerning finding in a client with COPD experiencing an exacerbation. This indicates increased work of breathing and can be a sign of respiratory failure, requiring immediate intervention. Oxygen saturation of 90% is low but not as concerning as the increased work of breathing. A respiratory rate of 24 breaths per minute can be within normal limits. Inspiratory crackles may be present in COPD due to airway inflammation but are not as concerning as the use of accessory muscles.

Correct Answer: A

Rationale: The correct answer is to place the side rails in an up position first. This action is essential to prevent the client from falling while the bed is being made. Assisting the UAP in turning the client (Choice B) is not the immediate priority. Providing instructions on bed-making techniques (Choice C) can wait until the safety of the client is ensured. Asking the client if they are comfortable (Choice D) is important but should come after ensuring the client's safety by raising the side rails.

Correct Answer: B

Rationale: In a client with left-sided heart failure, monitoring serum potassium levels is crucial. This helps in assessing kidney function and fluid balance. Elevated potassium levels can result from impaired kidney function, which is common in heart failure. Monitoring sodium levels (choice A) is important in heart failure but not specifically related to left-sided heart failure. Serum creatinine (choice C) reflects kidney function but is not the most critical value to monitor in this case. Serum glucose level (choice D) is important but not the priority when assessing left-sided heart failure.

Correct Answer: A

Rationale: The correct answer is A: 'Seek immediate medical assistance to evaluate the cause of these symptoms.' The symptoms described by the client, including nausea, dark-colored urine, and yellowish skin, are indicative of possible liver toxicity, a serious side effect of pioglitazone. Therefore, immediate medical evaluation is necessary to assess the severity of the condition and prevent further complications. Choices B, C, and D are incorrect: B advises discontinuing the medication without seeking immediate medical assistance, which could delay necessary treatment; C focuses solely on increasing fluid intake and monitoring urine color, overlooking the urgency of the situation; and D suggests continuing the medication when prompt evaluation is crucial in this scenario.
