Correct Answer: B

Rationale: A serum potassium level of 5.5 mEq/L is concerning in a client with ESRD scheduled for hemodialysis as it indicates hyperkalemia, which can lead to serious cardiac complications. Hyperkalemia can be exacerbated during hemodialysis, making it crucial to closely monitor serum potassium levels before the procedure. Monitoring serum creatinine, serum calcium, or hemoglobin levels is important in managing ESRD but is not the immediate focus before hemodialysis. Therefore, option B is the correct choice.

Correct Answer: A

Rationale: The correct answer is an Electrocardiogram (ECG). When a client with a history of atrial fibrillation presents with new-onset confusion, an ECG is crucial to assess for cardiac ischemia, which could be a potential cause of the confusion. A chest X-ray (Choice B) is not typically the first-line diagnostic test for evaluating confusion in a client with atrial fibrillation. Arterial blood gases (ABGs) (Choice C) are more useful in assessing oxygenation and acid-base balance rather than the cause of confusion in this scenario. While an echocardiogram (Choice D) provides valuable information about cardiac structure and function, it is usually not the initial diagnostic test needed in the evaluation of acute confusion in a client with atrial fibrillation.

Correct Answer: C

Rationale: The correct answer is C: Medicare. Title XVII of the Social Security Act of 1965 created the Medicare Program to provide medical insurance for individuals who are 65 years or older, disabled, or have permanent kidney failure. Medicare is the appropriate agency to refer a 66-year-old woman who is retiring and losing her employment-based health insurance. Choice A, the Woman, Infants, and Children program, is not suitable for this scenario as it provides assistance for low-income pregnant women, breastfeeding women, and young children. Choice B, Medicaid, is a program that helps individuals with low income and resources cover medical costs, which may not be applicable to this woman's situation. Choice D, the Consolidated Omnibus Budget Reconciliation Act provision, known as COBRA, allows employees to continue their group health insurance coverage after leaving their job but may not be the best option for this woman in this case.

Correct Answer: A

Rationale: Playing a board game with the client and initiating a conversation about stressors is the best choice to establish rapport and achieve the therapeutic goal of helping the client verbalize ways to cope with stress. Board games provide a relaxed and non-threatening environment, allowing the client to feel more comfortable and open up about their stressors. Choice B, conducting a formal therapy session, might be too structured and intimidating for the client, hindering open communication. Choice C, asking the client to write down their feelings, lacks the interactive and engaging aspect that a board game provides. Choice D, having a group discussion about stress management, may not be as effective initially as one-on-one interaction to build trust and rapport with the client.

Correct Answer: C

Rationale: Mucous plugging of the tracheostomy tube is the most concerning assessment finding in a client with a tracheostomy. It can lead to airway obstruction, which requires immediate intervention to ensure the client's airway remains patent. Crepitus around the tracheostomy site may indicate subcutaneous emphysema but is not as urgent as a blocked airway. A dry and cracked tracheostomy site may indicate poor skin integrity but does not pose an immediate threat to the client's airway. Yellowing of the skin around the tracheostomy site could suggest a localized infection, but it is not as critical as a potential airway obstruction caused by mucous plugging.
