Compared to photons, protons have what characteristic regarding exit dose?

In the passive scanning proton therapy (PSPT) approach, scatterers are used to spread the beam:

Enlargement of the heart that occurs because of overfilling of the heart chambers is

A proton therapy center with 3-story tall gantries experiences frequent treatment delays when switching between treatment rooms. The beam switching takes 30 seconds, but total room changeover takes 5-8 minutes. As a senior radiation therapist, you’re asked to analyze workflow efficiency. What systematic approach would most effectively reduce patient wait times while maintaining safety standards?

In a non-dynamically created energy system, which device is used to spread out the maximum dose during proton beam delivery:

A 70 kg patient is prescribed a heparin IV drip. The orders are: Heparin IV push bolus: 80 units/kg Heparin continuous IV infusion: 18 units/kg/hr Available: Heparin 25,000 units in 500 mL of 0.9% NS Part 1: Calculate the heparin IV push bolus dose and the corresponding volume to administer. Bolus dose: [6000] units (round to the nearest 1,000 units). Enter a numeric value only. Part 2: Calculate the flow rate for the continuous infusion. Flow rate: [25] mL/hr (round to the nearest whole number). Enter a numeric value only.

What does the acronym Q[Q], A[A], R[R] stand for when taking a patient history?

The provider orders glycopyrrolate 200 mcg IM as a single dose. The medication is supplied as 0.2 mg/mL. Question: How much volume (ml) will you deliver? Enter a numeric value only.

The Bragg peak phenomenon occurs because:

The provider orders Merrem 1 g IV piggyback, diluted in 100 mL of D5W, to infuse over 30 minutes. Question: What flow rate (in mL/hr) should you set on your infusion pump? Enter a numeric value only.
