Correct Answer: C

Rationale: The correct answer is C: Potassium. Furosemide is a diuretic that can cause potassium depletion due to increased urinary excretion. Monitoring potassium levels is crucial to prevent hypokalemia, which can lead to serious complications such as cardiac arrhythmias. Sodium (choice A) levels are not typically affected by furosemide. Glucose (choice B) monitoring is important with other medications like corticosteroids but is not directly related to furosemide use. Calcium (choice D) levels are not significantly impacted by furosemide.

Correct Answer: A

Rationale: Corrected Question: What are the potential complications of a patient receiving hemodialysis? Rationale: Infection and hypotension are common complications in patients undergoing hemodialysis. Pulmonary embolism and fluid overload (Choice B) are less common complications associated with hemodialysis. Blood clot formation and electrolyte imbalance (Choice C) are also potential complications but are not as common as infection and hypotension. Low blood pressure and nausea (Choice D) can occur but are not as prevalent as infection and hypotension.

Correct Answer: D

Rationale: In a situation where a verbal prescription for restraints is obtained for a client experiencing acute mania, the nurse should document the client's condition every 15 minutes. This frequent documentation allows for accurate monitoring of the client's condition, ensuring safety and compliance. Requesting a renewal of the prescription every 8 hours (Choice A) is not necessary as the focus should be on monitoring the client's condition. Checking the client's peripheral pulse rate every 30 minutes (Choice B) is not directly related to the need for restraints in this scenario. Obtaining a prescription for restraint within 4 hours (Choice C) is not a priority when a verbal prescription is already obtained and immediate action is needed for the client's safety.

Correct Answer: B

Rationale: The correct next step for the nurse is to irrigate the NG tube with sterile water. This action helps relieve blockages that may be causing the symptoms of nausea and decreased gastric secretions. Administering an antiemetic (Choice A) may mask the underlying issue without addressing the possible blockage. Increasing the suction setting (Choice C) is not indicated without first addressing the potential blockage. Replacing the NG tube (Choice D) is also premature before attempting to clear any obstructions.

Correct Answer: B

Rationale: When a client develops phlebitis at the IV site, the nurse's immediate action should be to discontinue the IV and notify the healthcare provider. Phlebitis is inflammation of the vein, and leaving the IV in place can lead to complications such as infection or thrombosis. Administering an anti-inflammatory medication (choice A) may not address the root cause and delay the necessary intervention. Applying a cold compress (choice C) may provide temporary relief but does not address the need to remove the source of inflammation. Increasing the IV flow rate (choice D) is contraindicated as it can exacerbate the phlebitis by causing more irritation to the vein.
