Correct Answer: B

Rationale: The correct answer is B: Tachycardia. In hypovolemia, the body responds to decreased fluid volume by increasing the heart rate (tachycardia) to maintain adequate circulation. Bradycardia (Choice A) is not expected in hypovolemia since the heart rate typically increases to compensate for the reduced blood volume. Increased blood pressure (Choice C) is unlikely in hypovolemia as the decreased fluid volume leads to decreased pressure. A bounding pulse (Choice D) is more associated with conditions like hyperthyroidism or fever, not specifically with hypovolemia.

Correct Answer: B

Rationale: The correct answer is B: Ammonia. In clients with cirrhosis, impaired liver function can lead to elevated levels of ammonia in the blood. Elevated ammonia levels can result in hepatic encephalopathy, a condition characterized by altered mental status. Serum albumin (Choice A) is typically decreased in cirrhosis due to the liver's reduced synthetic function. Bilirubin (Choice C) levels can be elevated in liver disease but may not always be the most specific marker for cirrhosis. Prothrombin time (Choice D) is prolonged in cirrhosis due to impaired liver synthesis of clotting factors.

Correct Answer: A

Rationale: The correct answer is A because amniocentesis is a procedure that confirms genetic disorders by analyzing the amniotic fluid surrounding the baby. Choice B is incorrect because amniocentesis is not used to assess lung maturity. Choice C is incorrect because some discomfort or pain may be felt during the procedure. Choice D is incorrect because amniocentesis does not primarily assess the amount of amniotic fluid around the baby.

Correct Answer: B

Rationale: Shortness of breath is a critical finding that can indicate a pulmonary embolism, a severe complication of DVT. This symptom suggests a potential life-threatening situation and requires immediate intervention. Calf tenderness, while common in DVT, is not as urgent as shortness of breath. Elevated blood pressure and a respiratory rate of 18/min are important to assess but are not typically as indicative of a serious complication like a pulmonary embolism.
