Correct Answer: C

Rationale: In a client with septic shock, a heart rate of 120 beats per minute is a critical clinical finding that requires immediate intervention. A rapid heart rate can indicate worsening sepsis and inadequate tissue perfusion. Correcting the underlying cause of the tachycardia and stabilizing the heart rate is crucial in managing septic shock. The other options, while important, do not represent an immediate threat to the patient's condition. A blood pressure of 90/60 mmHg may be expected in septic shock, a temperature of 100.4°F is mildly elevated, and a urine output of 30 ml/hour, though decreased, may not be an immediate concern in the context of septic shock.

Correct Answer: C

Rationale: Placing the client on NPO status is the priority action for a client with acute pancreatitis. This step is crucial to rest the pancreas, prevent pancreatic stimulation, and decrease enzyme production. By withholding oral intake, the digestive system is given a chance to rest and recover. Administering intravenous fluids may be necessary but should come after placing the client on NPO status. Pain medication can be administered once the client is stabilized. Assessing the client's abdomen for distention is important but is not the initial priority in managing acute pancreatitis.

Correct Answer: A

Rationale: The correct action for the nurse to implement is to observe for unilateral swelling. Unilateral swelling could indicate a deep vein thrombosis (DVT), which is a serious complication that requires immediate assessment. Administering pain medication or applying warm compress may not address the underlying cause of the symptoms. Notifying the healthcare provider should be done after assessing and identifying the issue of unilateral swelling.

Correct Answer: C

Rationale: In a client with hyperglycemic hyperosmolar syndrome (HHS), a serum osmolarity of 320 mOsm/kg is the most concerning laboratory value. This high osmolarity indicates severe dehydration, which can lead to serious complications. Elevated serum glucose levels (choice A) are expected in HHS but do not directly reflect dehydration. Blood pressure (choice B) and serum pH (choice D) are important parameters to monitor but are not the most concerning values in HHS compared to serum osmolarity.

Correct Answer: C

Rationale: A serum potassium level of 5.5 mEq/L is concerning in a client with DKA as it may indicate worsening hyperkalemia, requiring immediate intervention. Elevated serum potassium levels can lead to life-threatening cardiac arrhythmias. While elevated glucose and low bicarbonate are characteristic of DKA, hyperkalemia poses a higher immediate risk. Serum sodium within the normal range is not typically a primary concern in DKA.
