A nurse is performing a neurological examination on a client as part of a complete physical assessment.
The nurse should identify that cranial nerve XI is intact when the client performs which of the following actions?

The correct answer is C. Increased urinary output indicates that furosemide, a loop diuretic, is effective in reducing fluid retention and edema in clients with heart failure. The other findings are not indicative of furosemide effectiveness and may suggest adverse effects or complications. Decreased BUN level may indicate overhydration or liver dysfunction. Decreased hemoglobin level may indicate anemia or bleeding. Increased weight of 0.91 kg (2 lb) may indicate fluid overload or worsening heart failure.

The correct answer is D.

Choice A reason: “A. Using this machine increases my risk of overdose.” This statement is incorrect because PCA pumps are designed with safety mechanisms to prevent overdose. The pump is programmed to deliver a specific dose of medication at set intervals, and it will not dispense more medication than what is prescribed by the healthcare provider.

Choice B reason: “B. I can get pain medication any time as long as I press the button.” While it is true that the patient can self-administer medication, PCA pumps have a lockout interval that prevents the machine from delivering another dose until a certain amount of time has passed, ensuring that the patient cannot receive medication too frequently.

Choice C reason: “C. My partner can press my pain medication button for me if I am sleeping.” This statement is incorrect. Only the patient should press the button on the PCA pump to ensure that the medication is administered safely and according to the patient’s current level of pain. Allowing someone else to press the button could lead to unsafe dosing.

Choice D reason: “D. I will receive a limited amount of pain medication when I press the button.” This is the correct statement. The PCA pump allows the patient to administer a controlled amount of pain medication within safe limits set by the healthcare provider. The pump is programmed to deliver a specific dose of medication, and there is a limit to the number of doses that can be administered per hour.
