Correct Answer: B

Rationale: The correct answer is B: 'Has his weight changed in the last several days?' Sudden weight gain can indicate fluid retention, which is a common symptom of worsening heart failure. The inability to put on tight shoes can be due to fluid retention leading to swelling in the feet and ankles. Choices A, C, and D do not directly address the potential fluid retention issue and are less relevant in this scenario.

Correct Answer: D

Rationale: The correct action for the nurse to implement next is to delay administration until the pain is better described. It is essential to have a clear understanding of the nature and location of the pain before administering any analgesic to ensure appropriate and effective pain management. Requesting a pain assessment from another nurse or asking the client to describe the pain more precisely would also be appropriate actions to obtain more information before administering the analgesic. Administering the analgesic as requested without a clear description of the pain may not address the client's needs effectively and could potentially lead to ineffective pain management.

Correct Answer: A

Rationale: The correct answer is to check the blood glucose level. In a client with diabetes mellitus presenting with confusion and diaphoresis, it is important to assess the blood glucose level first to determine if the symptoms are due to hypoglycemia. Administering insulin immediately (Choice B) without knowing the blood glucose level can worsen the condition if the client is hypoglycemic. Offering a high-protein snack (Choice C) is not appropriate as the severity of hypoglycemia is unknown, and placing the client in a supine position (Choice D) is not the priority action for these symptoms.

Correct Answer: B

Rationale: The correct action to prevent complications during the infusion of potassium chloride is to monitor the infusion site for signs of infiltration. Rapid administration can lead to adverse effects, including cardiac arrhythmias. Using a syringe pump is not typically necessary for this infusion. Flushing the IV line with normal saline is a good practice but not directly related to preventing complications specifically during the infusion of potassium chloride.

Correct Answer: B

Rationale: In acute epiglottitis, the infected epiglottis becomes inflamed and can lead to sudden airway obstruction, which is a life-threatening emergency. This can cause difficulty breathing and necessitates immediate intervention to secure the airway. Increased carbon dioxide levels may occur due to inadequate ventilation resulting from airway obstruction, but the primary concern is the obstruction itself, not the carbon dioxide levels. Inability to swallow may be present due to pain and swelling in the throat but is not the immediate life-threatening complication associated with acute epiglottitis. Bronchial collapse is not a typical consequence of acute epiglottitis.
