A female client is admitted with end-stage pulmonary disease, is alert, oriented, and complaining of shortness of breath. The client tells the nurse that she wants 'no heroic measures' taken if she stops breathing, and she asks the nurse to document this in her medical record. What action should the nurse implement?

Correct Answer: A

Rationale: The correct action for the nurse to implement is to ask the client to discuss 'do not resuscitate' (DNR) wishes with her healthcare provider. This is important to ensure that the client makes informed decisions regarding her care. While documenting the client's wishes in her medical record is essential, it is crucial that the client discusses these wishes with the healthcare provider to understand the implications and have the DNR order legally documented. Asking the client to sign an advance directive is premature without a detailed discussion with the healthcare provider. Placing a 'Do Not Resuscitate' (DNR) order in the client's chart should only be done after the client has discussed and agreed upon this decision with the healthcare provider.

Correct Answer: C

Rationale: The correct answer is C: Serum sodium. In a client with chronic kidney disease (CKD) scheduled for hemodialysis, monitoring serum sodium levels closely is essential. Hemodialysis can cause rapid shifts in sodium levels, leading to electrolyte imbalances. While serum potassium (choice A) is important to monitor in CKD, it is not the most crucial before hemodialysis. Serum creatinine (choice B) is an indicator of kidney function but is not the most immediate concern before hemodialysis. Serum chloride (choice D) is not typically the primary electrolyte of concern in CKD patients before hemodialysis.

Correct Answer: A

Rationale: Administering insulin is the most crucial intervention in managing diabetic ketoacidosis. Insulin helps reduce blood glucose levels and correct metabolic acidosis, which are the primary issues in DKA. Monitoring urine output (Choice B) is important but not as critical as administering insulin. Assessing the client's level of consciousness (Choice C) is essential but does not directly address the underlying cause of DKA. Obtaining an arterial blood gas sample (Choice D) can provide valuable information but is not as urgent as administering insulin to address the immediate metabolic imbalance.

Correct Answer: C

Rationale: The correct answer is C: Use of accessory muscles. In a client with COPD and pneumonia, the use of accessory muscles indicates increased work of breathing and may signal respiratory failure. Immediate intervention is necessary to prevent further deterioration of the respiratory status. Choice A, an oxygen saturation of 90%, though low, may not require immediate intervention as it is above the typical threshold for initiating supplemental oxygen. Choice B, a respiratory rate of 24 breaths per minute, falls within the normal range for an adult and may not be an immediate cause for concern. Choice D, inspiratory crackles, are indicative of fluid in the lungs but may not require immediate intervention unless accompanied by other concerning signs like decreased oxygen saturation or increased respiratory distress.

Correct Answer: A

Rationale: In a client with COPD admitted with pneumonia, the priority intervention should be to administer oxygen therapy as prescribed. This is crucial to improve oxygenation, especially in a client with compromised respiratory function. Elevating the head of the bed can help with breathing but is secondary to ensuring adequate oxygenation. Obtaining a sputum culture and administering antibiotics are important steps in the treatment of pneumonia but come after ensuring adequate oxygen supply.
