When assessing the blood pressure of a school-aged child, using an adult cuff of normal size will affect the reading and produce a value that is

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. Carotid. The carotid arteries supply blood to the brain, and compressing both simultaneously can reduce cerebral blood flow, potentially causing dizziness, syncope, or loss of consciousness. Therefore, carotid pulses should be assessed one at a time.
B. Radial. The radial pulse can be safely assessed bilaterally at the same time since it does not affect central circulation or brain perfusion.
C. Brachial. The brachial pulse can also be assessed bilaterally without risk, as it does not impact blood flow to critical organs like the brain.
D. Femoral. The femoral pulse can be checked simultaneously on both sides to assess circulation and perfusion, especially in cases of suspected arterial insufficiency.
