Correct Answer: D

Rationale: When considering the use of restraints, Joint Commission guidelines emphasize the importance of attempting alternative measures before resorting to restraint application. This ensures that a comprehensive assessment is conducted and less restrictive interventions are explored. Using restraints solely based on their perceived level of restrictiveness, as stated in choice A, is not in line with the recommended approach. Restraints should not be used to manage wandering behavior, as indicated in choice C. Additionally, the statement in choice B regarding the duration of restraint use is inaccurate, as restraints on non-psychiatric patients should not exceed 24 hours according to The Joint Commission.

Correct Answer: A

Rationale: Specific gravity in urinalysis measures the concentration of solutes in urine compared to that of distilled water. This comparison helps in assessing the kidney's ability to concentrate urine properly. It is a valuable test even in dehydrated patients as it provides insights into renal function. Specific gravity can be measured using various methods, including a refractometer or reagent strips. Normal specific gravity readings of human urine typically range from 1.005 to 1.030. Choice A is correct as it accurately describes the purpose of specific gravity in urinalysis. Choices B and C are incorrect as specific gravity remains relevant in dehydrated patients and can be measured using different techniques, not solely a refractometer.

Correct Answer: C

Rationale: The nurse is responsible for coordinating the plan of care with other disciplines to ensure the client's safety. This action represents the implementation phase of the nursing process. During the implementation phase, the nurse puts the care plan into action, which includes coordinating with other healthcare team members like the physical therapy department. Assessment involves data gathering, planning involves goal setting, and evaluation involves determining the attainment of client goals.

Correct Answer: C

Rationale: The correct answer is 'absorption.' The three main functions of the digestive system are digestion, absorption, and elimination. Absorption refers to the process of absorbing nutrients and other substances from the digested food into the bloodstream. Choices A, B, and D are incorrect: Constriction is not a primary function of the digestive system, relaxation is not a distinct function in this context, and peristalsis is a muscular movement that aids in digestion but is not one of the three main functions of the digestive system.

Correct Answer: B

Rationale: During the implementation phase of the nursing process, the nurse is responsible for carrying out or delegating nursing interventions and documenting nursing activities and client responses in the medical records. Option A involves diagnosing, which is part of the nursing process's earlier phases. Option C pertains to planning, which precedes implementation. Option D relates to evaluation, which comes after the implementation phase.
