A child is brought to the emergency department after ingesting an unknown quantity of acetaminophen. What is the most important action for the nurse to take?

Correct Answer: D

Rationale: Obtaining serum acetaminophen levels is critical in determining the level of toxicity and guiding treatment. It helps to assess the risk of hepatotoxicity and determine the need for antidotal therapy with N-acetylcysteine. Assessing the child's level of consciousness (Choice A) is important but obtaining serum acetaminophen levels takes precedence as it directly guides the specific treatment required. Activated charcoal (Choice B) is not routinely used in acetaminophen poisoning. While notifying the poison control center (Choice C) is important, obtaining serum acetaminophen levels should be the immediate action to assess the child's condition and guide treatment.

Correct Answer: A

Rationale: Corrected Rationale: The correct procedure for a client with a large pleural effusion is thoracentesis. Thoracentesis is a diagnostic and therapeutic procedure used to remove fluid from the pleural space, which can help relieve symptoms associated with pleural effusion. Choice B (Endotracheal intubation) is incorrect as it is a procedure to secure the airway by placing a tube into the trachea. Choice C (Chest tube insertion) is incorrect as it is typically done to drain air or fluid from the pleural space over a longer period. Choice D (Bronchoscopy) is incorrect as it is a procedure used to visualize the airways and diagnose lung conditions, not specifically for pleural effusion removal.

Correct Answer: A

Rationale: In a client with chronic heart failure experiencing worsening dyspnea, the priority action for the nurse is to administer oxygen at 2 liters per nasal cannula. This helps improve oxygenation and alleviate respiratory distress. Administering a diuretic (Choice B) may be necessary but addressing oxygenation comes first. While assessing lung sounds (Choice C) is important, it is not the immediate priority when the client is in respiratory distress. Repositioning the client (Choice D) may help with comfort but does not address the underlying issue of inadequate oxygenation.

Correct Answer: C

Rationale: The correct answer is C. Cool extremities and weak peripheral pulses indicate compromised circulation, possibly due to inadequate arterial blood supply. This finding requires immediate intervention to prevent further complications such as tissue damage or non-healing ulcers. Option A, decreased pain and increased redness, can be a sign of improving wound condition. Option B, increased serous drainage, may indicate a normal part of the healing process. Option D, pitting edema, is common in venous leg ulcers and may not require immediate intervention unless severe and accompanied by other concerning symptoms.

Correct Answer: A

Rationale: The correct answer is to increase the dose of levothyroxine. In hypothyroidism, the body does not produce enough thyroid hormone, leading to symptoms like lethargy and cold intolerance. Increasing the dose of levothyroxine, which is a synthetic thyroid hormone replacement, helps correct the deficiency and alleviates the symptoms. Choice B, administering antipyretic medication, is incorrect as antipyretics are used to reduce fever, not treat hypothyroidism symptoms. Choice C, providing a warm blanket and increasing room temperature, may provide temporary comfort but does not address the underlying hormonal deficiency. Choice D, increasing fluid intake, is important for overall health but does not directly address the symptoms of hypothyroidism.
