Correct Answer: A

Rationale: A below-the-knee amputation requires immediate attention due to the risk of hemorrhage and shock, making it the highest priority. This type of injury can lead to significant blood loss and impaired perfusion, which can be life-threatening if not addressed promptly. While a 10 cm laceration, a fractured tibia, and a 95% full-thickness body burn are serious injuries requiring urgent care, they do not pose the same immediate threat to life as a below-the-knee amputation. The laceration may require suturing to control bleeding and prevent infection, the fractured tibia needs stabilization to prevent further damage and pain, and the burn necessitates immediate management to prevent complications, but they are not as acutely life-threatening as the amputation.

Correct Answer: C

Rationale: Albuterol is the correct choice for treating acute asthma attacks because it is a short-acting bronchodilator that provides quick relief by relaxing the muscles in the airways. Beclomethasone (choice A) and Salmeterol (choice B) are long-acting medications used for controlling and preventing asthma symptoms but are not for immediate relief during an acute attack. Montelukast (choice D) is a leukotriene receptor antagonist used for asthma maintenance therapy and not for acute asthma attacks.

Correct Answer: B

Rationale: The priority nursing action for a client with dehydration is to monitor electrolyte levels. Dehydration can cause imbalances in electrolytes such as sodium and potassium, affecting essential bodily functions. Monitoring electrolyte levels is crucial to promptly identify and correct any imbalances. While administering oral fluids (Choice A) is vital in treating dehydration, monitoring electrolyte levels takes precedence as it directly addresses the underlying imbalance. Administering antiemetics (Choice C) may be necessary for nausea and vomiting but is not the priority over electrolyte monitoring. Encouraging bed rest (Choice D) can conserve energy but is not as critical as monitoring electrolyte levels to prevent complications related to electrolyte imbalances.

Correct Answer: B

Rationale: The correct first step in managing a client with delirium is to identify any reversible causes of delirium. This is crucial because addressing the underlying cause can help in resolving delirium more effectively. Administering sedative or antipsychotic medications without addressing the root cause may not be helpful and can even worsen the condition. Limiting environmental stimulation, although important, is not the primary step in managing delirium.

Correct Answer: B

Rationale: The most appropriate nursing intervention when a client with a nasogastric tube experiences nausea and a decrease in gastric secretions is to aspirate the gastric contents with a syringe. This action helps relieve nausea by removing excess fluid and gas. Option A, irrigating the nasogastric tube with distilled water, is not indicated as it does not address the underlying issue of decreased gastric secretions. Option C, administering an antiemetic medication, may provide symptomatic relief but does not address the mechanical issue of decreased flow in the nasogastric tube. Option D, inserting a new nasogastric tube, is not necessary unless there are specific complications or obstructions in the current tube.
