The physician orders tramadol 100 mg oral three times a day. Tramadol is available in 50-mg tablets. How many tablets would the nurse administer with each dose?

A. "The PCA will give additional pain medication whenever the button is pushed." PCA pumps have lockout intervals to prevent overdose, so pushing the button repeatedly will not always result in additional medication.
B. "Wait until the pain becomes severe before pushing the PCA button." PCA is most effective when used at the onset of pain rather than waiting until it becomes severe, which can make pain harder to control.
C. "The PCA will deliver medication through the IV until the pain is all gone." PCA provides controlled doses of medication but does not eliminate pain entirely. The goal is pain management, not complete pain relief.
D. "You or a designated family member are the only one who gets to push the PCA button—nobody else may do so." PCA is designed for patient-controlled use, and only the patient (or a designated, trained family member in special cases) should operate it to ensure proper dosing and safety.

A. 200/92. This format does not include the muffling point (Phase IV), which is important in some clinical settings, such as in critically ill patients or those with vascular diseases.
B. 100/200/92. This order is incorrect because the systolic pressure should always be listed first, followed by the diastolic components.
C. 200/100. This format omits the point at which sounds completely disappear (Phase V), which is the true diastolic pressure in most cases. However, in some individuals, particularly those with conditions like aortic regurgitation, the muffling point may be recorded as an additional reading.
D. 200/100/92. The correct way to document blood pressure when Korotkoff sounds muffle before disappearing is to include all three values: the systolic pressure (Phase I), the point of muffling (Phase IV), and the diastolic pressure (Phase V). This ensures a complete and accurate blood pressure recording.
