Correct Answer: C

Rationale: A serum potassium level of 3.0 mEq/L should be monitored closely in a client who is postoperative following a thyroidectomy to detect any electrolyte imbalances. After a thyroidectomy, there is a risk of hypokalemia due to the effects of anesthesia, stress response, and the surgical procedure itself. Monitoring serum potassium levels is crucial as hypokalemia can lead to cardiac arrhythmias and muscle weakness. Serum calcium, sodium, and chloride levels are important but not the primary focus following a thyroidectomy, making them incorrect choices.

Correct Answer: A

Rationale: In a 60-year-old female client with a family history of ovarian cancer and an abdominal mass, further evaluation involving surgery may be needed to rule out ovarian cancer. The presence of an abdominal mass raises suspicion for a possible malignancy, and a negative Pap smear result does not rule out ovarian cancer. A pelvic exam alone may not provide sufficient information to confirm or rule out ovarian cancer. Continuing Pap smear evaluations every six months or waiting for one additional negative Pap smear in six months is not appropriate in this scenario, as the abdominal mass requires immediate attention and further evaluation.

Correct Answer: C

Rationale: A fever of 100.4°F is the most concerning assessment finding in a client with ESRD scheduled for hemodialysis. This elevation in temperature may indicate an underlying infection, which can lead to serious complications in individuals with compromised renal function. Prompt intervention is necessary to prevent the spread of infection and deterioration of the client's condition. The other vital signs mentioned, such as blood pressure, heart rate, and respiratory rate, while important to monitor, are within acceptable ranges and do not pose an immediate threat like a fever indicative of infection.

Correct Answer: B

Rationale: Subcutaneous emphysema is the correct answer as it is most concerning in a client with a chest tube following a pneumothorax. It may indicate a pneumothorax recurrence or air leak, requiring immediate intervention to prevent complications. Oxygen saturation of 94% is acceptable and does not require immediate intervention. Crepitus around the insertion site may be a normal finding after chest tube placement and does not necessarily indicate a complication. Drainage of 50 ml per hour is within the expected range for a chest tube and does not require immediate intervention.

Correct Answer: B

Rationale: In a client with chronic kidney disease (CKD) receiving erythropoietin therapy, elevated blood pressure is the most concerning finding. Elevated blood pressure can indicate worsening hypertension, which requires immediate intervention to prevent further damage to the kidneys and other organs. Increased fatigue (choice A) is a common symptom in CKD but may not be as acutely concerning as elevated blood pressure. Elevated hemoglobin (choice C) can be an expected outcome of erythropoietin therapy and is not necessarily concerning. Low urine output (choice D) is important to monitor in CKD but may not be as immediately concerning as elevated blood pressure in this context.
