A client with a history of cardiac dysrhythmias is admitted to the hospital with the diagnosis of dehydration. The nurse should anticipate that the physician will order;

Correct Answer: D

Rationale: A client with a history of cardiac dysrhythmias and dehydration requires careful monitoring and management of fluid and electrolyte balance. The most appropriate intervention for rapid correction of dehydration in this scenario is a rapid IV infusion of an electrolyte and glucose solution. This method allows for the quick replacement of fluids and essential electrolytes to restore the client's hydration status efficiently and effectively. Administering fluids orally may not be adequate in this situation, and NG replacement of fluids and nutrients may not be necessary if the client's condition can be managed through IV therapy. Therefore, option D is the most appropriate choice for this client.

Correct Answer: C

Rationale: The precaution a nurse should take to minimize the risk of deaths occurring when potassium chloride is used incorrectly to flush a lock or central venous catheter is to read labels carefully on vials containing flush solutions for locks. This is essential to ensure that the correct solution is being used and to prevent accidental administration of potassium chloride, which can be fatal if used inappropriately. By carefully checking the labels, the nurse can confirm that they are using the correct flush solution and avoid any harmful errors. This simple precaution can help in ensuring patient safety and preventing adverse outcomes.

Correct Answer: D

Rationale: Epinephrine is a vasoconstrictor, which means it causes blood vessels to narrow. When applied locally to the site of a nosebleed, epinephrine constricts the blood vessels in the nose, slowing down and stopping the bleeding. By constricting the blood vessels, epinephrine helps to reduce the blood flow to the area, allowing a clot to form and stop the bleeding. This is why option D, "It will constrict your vessels and slow down the bleeding," is the best response by the nurse to explain how epinephrine will help treat a nosebleed.

Correct Answer: A

Rationale: An initial sign or symptom of acute bronchitis is a nonproductive cough. This type of cough produces little to no phlegm or sputum. As the condition progresses, the cough may become productive, with the production of thick yellow or green mucus. Other common symptoms of acute bronchitis may include chest discomfort, fatigue, mild fever, and sore throat. Labored breathing is more commonly associated with conditions such as pneumonia or asthma, while anorexia and gastric ulceration are not typically initial signs of acute bronchitis.

Correct Answer: A

Rationale: Warfarin is an anticoagulant medication that works by inhibiting the production of certain clotting factors in the liver, thus prolonging the time it takes for blood to clot. An elevated INR level indicates that the blood is taking longer to clot than desired, potentially putting the patient at risk for bleeding. Vitamin K is the antidote for warfarin because it helps the liver produce these clotting factors, ultimately reversing the effects of warfarin and promoting normal blood clotting. Administering Vitamin K helps lower the INR level and reduce the risk of bleeding in patients on warfarin therapy. Therefore, in this scenario, Vitamin K would be the appropriate antidote to use for the patient with an elevated INR level.
