The CRRN Examination: Preparation and Strategies

Abstract

The Certified Rehabilitation Registered Nurse (CRRN) certification has become a visible and coveted credential for the practicing rehabilitation nurse. This article presents practical information about preparing for and taking the CRRN examination. Strategies for implementing a study plan and organizing information to increase retention are suggested. In addition, this article offers recommendations for decreasing test anxiety and increasing confidence in test taking.

Dioxaborine- and Indole-Terminated Polymethines: Effects of Bridge Substitution on Absorption Spectra and Third-Order Polarizabilities

“…Zero-frequency (static) values of the real part of the third-order polarizability, Re(γ) static , can be estimated from the transition energies, E , transition dipole moments, M , and changes in state dipole moment, Δμ, linking ground, first excited, and higher-lying excited states (denoted by g, e, and e′ subscripts, respectively) according to the perturbation-theory derived eq 1. − Re false( normalγ false) static ∝ − M ge 2 E ge 3 normalN + M ge 2 normalΔ normalμ ge 2 E ge 3 normalD + ∑ normale ′ M ge 2 M ee ′ 2 E ge 2 E ge ′ T …”

Nonlinear Optical Properties of X(C6H5)4 (X = B–, C, N+, P+): A New Class of Molecules with a Negative Third-Order Polarizability

“…If the electric field of light is treated as a perturbation, γ can be expressed in terms of the molecular properties as a sum-over-(electronic) states (SOS) expression: where the ℏω p,q,r terms denote the photon energies; g , the electronic ground state; u , v , and w , the electronic excited states; E gu , the transition energy from state g to state u ; μ̂ j , the electric dipole moment operator along molecular axis j ; μ̅ j , the transition dipole moment between states u and v only if u and v are different, or if u and v are the same, then μ̅ j is the difference between the state dipole moments of state u and the ground state; i , the imaginary unit; Γ gu , a damping factor for excited state u , which is related to the excited-state lifetime; and I p,q,r , the average over the terms obtained by simultaneous permutation of the incident photon frequency and the dipole moment operator. In molecular systems where only one excited state is strongly coupled to the ground state and the primary components of the state dipole moments and transition dipole moments are aligned along one molecular axis x , the full SOS expression can be simplified to an essential-state model with three terms, − which in the static limit appears as …”

Interdisciplinary communication in inpatient rehabilitation facility: evidence of under-documentation of spatial neglect after stroke

“…The CRRN program is administered by the Rehabilitation Nursing Certification Board, which is a component of the Association of Rehabilitation Nurses. Successful completion of CRRN certification indicates a specialized level of nursing focused on caring for the patient undergoing physical rehabilitation [25]. In the course of providing much personal care for daily living, nurses working in an IRF encounter symptoms of spatial neglect most frequently than other professionals [26].…”
