Correct Answer: B

Rationale: Reorienting the client frequently is the most important nursing intervention in this scenario. It helps reduce confusion and agitation, which are common symptoms of acute delirium in hospitalized elderly clients. Requesting a psychiatric consult (choice A) may be necessary if the reorientation does not improve the client's condition or if there are underlying psychiatric concerns, but reorientation should be attempted first. Administering antipsychotic medications (choice C) should not be the initial intervention as they can have adverse effects in elderly individuals. Obtaining a sitter (choice D) may provide support but does not directly address the client's disorientation and agitation.

Correct Answer: C

Rationale: The correct answer is C: Serum creatinine level of 2.0 mg/dl. In a client with ESRD receiving hemodialysis, serum creatinine should be closely monitored. Elevated creatinine levels indicate impaired kidney function. Monitoring serum calcium levels (Choice A), serum potassium levels (Choice B), and serum sodium levels (Choice D) is also important in clients with ESRD, but the most crucial indicator of kidney function in this case is serum creatinine.

Correct Answer: A

Rationale: The correct answer is A: Multiple convictions for misdemeanors and class B felonies. Clients with antisocial personality disorder often engage in behaviors that disregard societal rules and norms, leading to legal issues and criminal activities. This behavior is characteristic of individuals with antisocial personality disorder. Choices B, C, and D are incorrect because individuals with this disorder are less likely to have stable employment, strong family relationships, or seek help when needed due to their pattern of defiance and disregard for authority and rules.

Correct Answer: C

Rationale: The correct answer is to obtain a list of medications taken for cardiac history. The client's presentation is indicative of digitalis toxicity, commonly associated with medications like digoxin (Lanoxin) used in heart failure treatment. Understanding the client's medication history, particularly the use of digoxin, is crucial in confirming and managing digitalis toxicity. Assessing distal pulses and signs of peripheral edema (Choice A) may be relevant in heart failure but are not the priority in this case. Determining the client's level of orientation and cognition (Choice B) and asking about exposure to environmental heat (Choice D) are not directly related to the client's current symptoms and are less pertinent in this scenario.

Correct Answer: A

Rationale: A serum potassium level of 6.5 mEq/L is most concerning in a client with CKD as it indicates severe hyperkalemia, requiring immediate intervention. Hyperkalemia can lead to life-threatening cardiac arrhythmias. Serum sodium levels within the normal range (135 mEq/L) are not immediately concerning. Serum creatinine of 2.0 mg/dL may indicate impaired kidney function but does not require immediate intervention for hyperkalemia. Blood glucose of 150 mg/dL is within normal limits and does not directly correlate with hyperkalemia in this scenario.
