Correct Answer: A

Rationale: The correct answer is A. An overdose of thyroid preparation generally manifests symptoms of an agitated state such as tremors, palpitations, shortness of breath, tachycardia, increased appetite, agitation, sweating, and diarrhea. Palpitations and shortness of breath are signs of excessive thyroid medication.

Choices B, C, and D are incorrect symptoms for a dosage that is too high. Bradycardia and constipation, lethargy and lack of appetite, muscle cramping and dry, flushed skin are more indicative of hypothyroidism or an insufficient dosage of levothyroxine.

Correct Answer: C

Rationale: The correct answer is C. Confusion and altered mental status are the most concerning clinical findings in a client with cirrhosis because they may indicate hepatic encephalopathy, a serious complication that requires immediate intervention. Peripheral edema (choice
A) and increased abdominal girth (choice
B) are common manifestations of cirrhosis but are not as acutely concerning as signs of hepatic encephalopathy. Yellowing of the skin (choice
D) is due to jaundice, which is already present in the client and does not directly indicate a worsening condition like confusion and altered mental status.

Correct Answer: A

Rationale: The correct answer is A: Decreased abdominal girth. In a client with cirrhosis of the liver, a LeVeen shunt is used to treat ascites, which is the accumulation of fluid in the peritoneal cavity. A decrease in abdominal girth indicates that the shunt is effectively draining the ascitic fluid, relieving the client's abdominal distension.
Choice B, increased blood pressure, is incorrect as a LeVeen shunt is not expected to impact blood pressure.
Choice C, clear breath sounds, is unrelated to the effectiveness of a LeVeen shunt in managing ascites.
Choice D, decreased serum albumin, is also not a direct indicator of the shunt's effectiveness in draining ascitic fluid.

Correct Answer: C

Rationale: An oxygen saturation of 85% is significantly low for a client with COPD and indicates hypoxemia, requiring immediate intervention. In COPD, the body's ability to oxygenate adequately is already compromised, so a saturation of 85% is particularly concerning. A barrel-shaped chest and use of accessory muscles are common findings in COPD due to chronic air trapping and increased work of breathing. While a respiratory rate of 28 breaths per minute is elevated, a low oxygen saturation is a more critical finding that necessitates prompt attention.

Correct Answer: C

Rationale: A serum bicarbonate level of 18 mEq/L requires immediate intervention in a client with diabetic ketoacidosis (DK
A). A low serum bicarbonate level indicates metabolic acidosis, which can be life-threatening. This condition needs urgent correction to restore acid-base balance. Serum glucose of 300 mg/dl, serum potassium of 5.5 mEq/L, and serum sodium of 135 mEq/L are abnormal values, but they do not pose an immediate threat to the client's life compared to the metabolic acidosis indicated by the low serum bicarbonate level.
