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: B

Rationale: Step-by-step rationale for choice B being correct: 1. Dehydration leads to electrolyte imbalances, which can exacerbate cardiac dysrhythmias. 2. Small frequent intake of fluids like juices, broth, or milk helps in gradual rehydration without overwhelming the cardiovascular system. 3. This approach allows for better absorption of fluids and nutrients, promoting hydration without causing sudden shifts in electrolyte levels. Summary of why other choices are incorrect: A: Just drinking a glass of water every hour may not address electrolyte imbalances or provide adequate hydration for a client with cardiac dysrhythmias. C: NG replacement may not be necessary if the client can tolerate oral intake, and it is more invasive than needed. D: A rapid IV infusion may lead to sudden changes in electrolyte levels, potentially worsening the dysrhythmias.

Correct Answer: D

Rationale: The correct answer is D: Vitamin D. Vitamin D is essential for the absorption of calcium in the intestines. Without sufficient vitamin D, the body cannot effectively absorb calcium, leading to potential issues with calcium absorption. Vitamin A (choice A) is not directly involved in calcium absorption. Vitamin B (choice B) and Vitamin C (choice C) also do not play a significant role in calcium absorption. Therefore, the lack of Vitamin D is the most likely cause for problems with calcium absorption.

Correct Answer: B

Rationale: The correct answer is B: prothrombin time. In liver cirrhosis, the liver's ability to produce clotting factors is impaired, leading to prolonged prothrombin time. This indicates an increased risk of bleeding. Choice A is incorrect as carbon dioxide levels are not typically affected by liver cirrhosis. Choice C, gastric pH, is unrelated to liver function. Choice D, white blood cell count, is not directly affected by liver cirrhosis. Therefore, the alteration in prothrombin time is the most relevant laboratory value to monitor in this case.

Correct Answer: C

Rationale: The correct answer is C: Painful and frequent urination. Cloudy penile discharge is a common symptom of urethritis, which is inflammation of the urethra. Painful and frequent urination are classic symptoms of urethritis due to irritation and inflammation of the urinary tract. Throat or rectal infection (choice A) are not typically associated with urethritis. Chancres or vesicles on the genitals (choice B) are more indicative of sexually transmitted infections like syphilis or herpes. Oliguria and flank pain (choice D) are more suggestive of kidney or urinary tract issues rather than urethritis.

Correct Answer: C

Rationale: Step 1: Reading labels carefully on vials containing flush solutions for locks is crucial to ensure the correct solution is being used. Step 2: Potassium chloride should not be used to flush locks as it can be fatal if administered incorrectly. Step 3: By carefully reading labels, the nurse can verify that the correct solution is being used, thus minimizing the risk of using potassium chloride. Summary: - Choice A is incorrect as using a dilute form of potassium chloride does not address the issue of incorrect administration. - Choice B is incorrect as warming the solution does not prevent the risk associated with using potassium chloride. - Choice D is incorrect as replacing locks does not address the root cause of the issue, which is improper administration.

Correct Answer: A

Rationale: Step-by-step rationale: 1. Acute bronchitis is characterized by inflammation of the bronchial tubes. 2. An initial sign of acute bronchitis is a nonproductive cough due to irritation of the bronchial tubes. 3. Anorexia and labored breathing may occur later as the condition progresses. 4. Gastric ulceration is not typically associated with acute bronchitis. Therefore, choice A (Nonproductive cough) is the correct answer as it aligns with the characteristic symptom of acute bronchitis, while the other choices are not typically observed in the initial stages of the condition.

Correct Answer: C

Rationale: The correct answer is C: chronic biliary inflammation or obstruction. Biliary cirrhosis is a condition characterized by scarring of the liver due to long-term damage to the bile ducts. Chronic biliary inflammation or obstruction can lead to the build-up of bile in the liver, causing damage over time. Acute viral hepatitis (choice A) typically does not directly cause biliary cirrhosis. Alcohol hepatotoxicity (choice B) is more commonly associated with alcoholic liver disease rather than biliary cirrhosis. Hepatic failure with prolonged venous hepatic congestion (choice D) may lead to liver cirrhosis, but it is not specific to biliary cirrhosis.

Correct Answer: A

Rationale: The correct answer is A: Naturally acquired passive immunity. This type of immunity occurs when antibodies are passed from mother to baby through the placenta or breast milk, providing temporary protection. The baby does not produce its antibodies, hence it is passive. Choice B, naturally acquired active immunity, involves the body producing its antibodies after exposure to a pathogen. Choice C, artificially acquired passive immunity, involves receiving preformed antibodies from an external source. Choice D, artificially acquired active immunity, involves the body producing antibodies in response to vaccination.

Correct Answer: B

Rationale: The correct answer is B: Do not stop medication abruptly. Abruptly stopping propranolol can lead to rebound hypertension and potentially life-threatening complications. The nurse should emphasize the importance of gradual tapering under medical supervision to avoid adverse effects. A: Having potassium levels checked is not directly related to propranolol use for hypertension management. C: Changes in appetite are not specific to propranolol use and may not be a significant concern compared to abrupt cessation of the medication. D: Resuming usual daily activities is important but not as crucial as the correct instruction to avoid abrupt discontinuation of propranolol.
