Correct Answer: A

Rationale: Nadolol (Corgard) should be removed if found inside the fridge because it is supposed to be stored at room temperature between 59 to 86 ºF (15 and 30 ºC) away from heat, moisture, and light. Storing it in the refrigerator can alter its effectiveness and stability. Option B, the opened Humulin N injection, should not be stored in the refrigerator as it is an in-use product and can remain at room temperature for a certain period as per manufacturer guidelines. Option C, Urokinase (Kinlytic), and Option D, Epoetin alfa IV (Epogen), do not require refrigeration and can be stored at room temperature. Therefore, Nadolol (Corgard) is the drug that should be removed from the fridge.

Correct Answer: D

Rationale: The correct answer is that no special orders are necessary for a KUB radiography test. It is important to inform the client to remove any clothing, jewelry, or objects that may interfere with the test. Option A is incorrect because there is no need for the client to be NPO before this examination. Option B is incorrect as enemas are not routinely administered prior to a KUB radiography test. Option C is incorrect as there is no need to medicate the client with furosemide before this examination.

Correct Answer: A

Rationale: Green vegetables and liver are rich sources of folic acid. Green vegetables like spinach, asparagus, and broccoli are high in folic acid content. Liver, especially from chicken or beef, is also a good source of folic acid. Yellow vegetables and red meat (choice B) do not contain as high a concentration of folic acid as green vegetables and liver. Carrots (choice C) are nutritious but do not have the highest concentration of folic acid. Milk (choice D) is not a significant source of folic acid compared to green vegetables and liver.

Correct Answer: A

Rationale: The most crucial action for the nurse when preparing to administer enteral feeding via a nasogastric tube is to verify the correct placement of the tube. Proper placement of the tube is vital to prevent complications such as aspiration into the lungs. The definitive methods to confirm the position of the nasogastric tube include visualization through an x-ray or aspirating stomach contents and checking their pH (usually pH 1 to 5). Aspirated stomach content can also be tested for bilirubin to confirm placement in the stomach. Choice B, checking that the feeding solution matches the dietary order, is important for ensuring the correct nutrition is provided but is not as critical as verifying tube placement to prevent potential harm. Choice C, aspirating gastric contents to determine the amount of the last feeding remaining in the stomach, is a common nursing practice but is not the most crucial action when compared to ensuring correct tube placement. Choice D, ensuring that the feeding solution is at room temperature, is relevant for patient comfort and preventing thermal injury but is not as essential as confirming correct tube placement to prevent serious complications.

Correct Answer: A

Rationale: The correct answer is Amitriptyline (Elavil) as it is a tricyclic antidepressant commonly used to treat symptoms of depression and anxiety disorders. Amitriptyline works by increasing the levels of certain neurotransmitters in the brain to improve mood. Choices B, C, and D are incorrect. Calcitonin is a hormone used in the treatment of osteoporosis; Pergolide mesylate is a dopamine agonist used in Parkinson's disease; Verapamil is a calcium channel blocker used to treat high blood pressure and certain heart conditions, not mental health disorders.
