Which of the tractions is used to treat fractures of the humerus?

Correct Answer: B

Rationale: Humerus fractures require specific traction. Bryant's traction (choice A) treats femoral fractures in children. Overhead suspension traction (choice B) stabilizes humeral fractures, aligning via arm suspension. Thomas splint (choice C) is for femur fractures. 90-90 traction (choice D) suits femoral shaft issues. B is correct, standard for humerus. Nurses apply it, check alignment, and prevent skin breakdown, aiding healing.

Correct Answer: C

Rationale: Autogenic training (C) is self-suggestion or self-hypnosis, using phrases to induce relaxation (e.g., 'my arms are heavy'). Biofeedback (A) relies on machines, meditation (B) on focus, and visualization (D) on imagery not self-hypnosis. Autogenic training, per Schultz, shifts autonomic responses via mental cues, aligning with the definition, making C correct.

Correct Answer: C

Rationale: Maintaining eye contact (C) is least effective with aggressive clients; it can escalate tension, per de-escalation guidelines. Calm approach (A), expression (B), and isolation (D) soothe or manage behavior. Eye contact may provoke, making C incorrect.

Correct Answer: C

Rationale: Therapeutic communication (C) is reciprocal, trust-based, and goal-oriented, per Peplau, identifying needs and setting mutual goals. Nurse-directed (A) lacks reciprocity, warmth (B) is partial, assessment (D) narrows scope. C fully defines it, making it correct.

Correct Answer: B

Rationale: BP 60/40 (B) is highest priority; severe hypotension threatens perfusion, per ABCs (circulation). Pain (A), fever (C), and cyanosis (D) are urgent but secondary to life-threatening shock. B demands immediate action, making it correct.
