Correct Answer: B

Rationale: When a client develops phlebitis at the IV site, the immediate action the nurse should take is to discontinue the IV and notify the provider. Phlebitis is inflammation of the vein, and if left untreated, it can lead to serious complications such as infection, thrombosis, or sepsis. Removing the IV line helps prevent further irritation and infection. Applying a warm compress (Choice A) may provide some relief but does not address the root cause. Monitoring for signs of infection (Choice C) is important but not the immediate action needed to address phlebitis. Administering an anti-inflammatory medication (Choice D) may be prescribed by the provider but is not the first step in managing phlebitis.

Correct Answer: A

Rationale: The correct intervention to manage fatigue in a client receiving chemotherapy is to encourage the client to take short naps during the day. Fatigue is a common side effect of chemotherapy, and allowing the client to rest can help combat this symptom. Instructing the client to remain on bedrest (Choice B) is not recommended as it may lead to deconditioning and worsen fatigue. Providing a high-calorie diet (Choice C) may be beneficial for overall nutrition but does not directly address fatigue. Encouraging the client to increase activity levels (Choice D) may exacerbate fatigue instead of alleviating it.

Correct Answer: C

Rationale: The correct answer is C: Serum potassium. Spironolactone is a potassium-sparing diuretic, meaning it helps the body retain potassium. Therefore, the nurse should monitor the client's serum potassium levels to prevent hyperkalemia, which can be a potential side effect of spironolactone. Monitoring total bilirubin levels (A) is not specifically required for clients taking spironolactone. Urine ketones (B) are not directly influenced by spironolactone use. Platelet count (D) is not typically monitored in clients taking spironolactone.

Correct Answer: A

Rationale: When managing a patient with a fever, the appropriate approach involves administering antipyretics to reduce the fever and monitoring the patient's vital signs to assess their response to treatment. Administering antipyretics helps to lower the body temperature and manage fever symptoms effectively. Monitoring vital signs is crucial to ensure the patient's condition is improving. Providing cold compresses, as mentioned in choice B, can help in managing fever symptoms, but it does not address the root cause of the fever. Encouraging the patient to rest, as stated in choice C, is beneficial for recovery, but increasing fluid intake is essential to prevent dehydration. Restricting fluid intake and providing bed rest, as in choice D, can lead to dehydration and hinder the body's ability to fight off the infection causing the fever. Therefore, the best course of action for a healthcare provider is to administer antipyretics while closely monitoring the patient's vital signs.

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.
