An adult client is on extreme pain. He is moaning and grimacing. What is the best way to assess the client's pain?

Correct Answer: B

Rationale: Rating pain on a smiley scale (B) is best for an adult in extreme pain; it quantifies subjective experience, per pain assessment tools. Physical assessment (A) is secondary, listening (C) misses rating, observing (D) lacks precision. B captures intensity, making it correct.

Correct Answer: C

Rationale: Upper and Lower GI series use a body system framework (C), targeting digestive system, per assessment types. Functional (A) assesses ADLs, head-to-toe (B) and cephalocaudal (D) are physical sweeps. C fits organ focus, making it correct.

Correct Answer: A

Rationale: Blood pressure is the force of blood against vessel walls (A), per its definition in physiology. Systolic is the highest pressure (B), not lowest false. BP involves sympathetic and parasympathetic systems (C), not just one. Sphygmomanometers measure at the upper arm, not forearm (D). A accurately captures BP's essence, validated by clinical practice, making it the best and correct description.

Correct Answer: C

Rationale: Hyperpnea (C) is increased depth and rate of respiration, common in strenuous exercise, per respiratory terminology. Kussmaul's (A) is deep, rapid breathing in metabolic acidosis, not exercise. Eupnea (B) is normal breathing, and bradypnea (D) is slow. Hyperpnea matches the physiological response to heightened oxygen demand during activity, making C the correct answer based on its specific context.

Correct Answer: B

Rationale: Palliative care relieves symptoms without curing (B), per WHO definition focusing on quality of life. It's for serious illness, not just terminal (A), doesn't need high tech (C), and differs from hospice (D) palliative spans broader stages. B best captures its symptom-focused essence, making it the correct description.
