Correct Answer: A

Rationale: Administering oxygen therapy as prescribed is the initial priority when managing an exacerbation of COPD. In COPD exacerbations, the primary concern is hypoxemia due to impaired gas exchange. Administering oxygen helps to improve oxygenation and prevent further complications. Elevating the head of the bed can aid in breathing comfort but is not the priority over ensuring adequate oxygen supply. Assessing the client's level of consciousness is important but comes after ensuring oxygenation. Obtaining a sputum culture is relevant for identifying pathogens but is not the immediate priority in addressing hypoxemia.

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.

Correct Answer: A

Rationale: The correct answer is A: Review the staff nurse job description to ensure that it is clear, accurate, and current. By ensuring that job descriptions are clear and up-to-date, nurse-managers can reduce ambiguity and confusion about roles and responsibilities. Choice B, conducting regular meetings to clarify roles, may help but may not address the root cause of ambiguity. Choice C, increasing communication between team members, is important but may not specifically target role ambiguity. Choice D, providing additional training for new nurses, is valuable but may not directly address role ambiguity among existing staff.

Correct Answer: A

Rationale: Evaluating blood clotting factors daily is crucial when a client is on heparin therapy to monitor for potential complications such as bleeding or clotting issues. This monitoring helps ensure that the heparin dose is within the therapeutic range and reduces the risk of bleeding or clotting complications. Encouraging incentive spirometry use is beneficial for preventing atelectasis and improving lung function, but in this scenario, monitoring blood clotting factors takes precedence. Administering pain medication as needed is important for the client's comfort but is not the priority in managing a pulmonary embolism. Monitoring for signs of bleeding is important due to heparin therapy, but evaluating blood clotting factors provides more specific information on the client's response to treatment.

Correct Answer: C

Rationale: Collecting a urine specimen for routine urinalysis is the next appropriate intervention. The symptoms described, including facial edema and tea-colored urine, are indicative of glomerulonephritis, a condition affecting the kidneys. A urine specimen can help assess renal function and the presence of blood and protein in the urine, which are common in glomerulonephritis. Performing an otoscopic examination (Choice A) is not relevant to the presenting symptoms. Measuring the child's abdominal girth (Choice B) is not necessary at this point as it does not directly address the urinary symptoms. Obtaining a blood specimen for serum electrolytes (Choice D) may provide information about electrolyte imbalances but is not the most appropriate initial step in this case.
