Nokea
Which of the following is more life threatening?
- A. BP=180/100
- B. BP=160/120
- C. BP=90/60
- D. BP=80/50
Correct Answer: D
Rationale: BP 80/50 is most life-threatening e.g., hypoperfusion risks failure vs. 180/100 (hypertension), 160/120 (severe), 90/60 (borderline). Nurses prioritize this e.g., fluids for stability, per hemodynamics.

Which one of the following four clients is most likely to tolerate pain best?
- A. a client with rheumatoid arthritis
- B. a client who has terminal cancer in stage 1 of grief
- C. an athlete having a knee surgery to prolong his career
- D. a client who has a migraine headache
Correct Answer: C
Rationale: An athlete undergoing knee surgery likely tolerates pain best, motivated by career goals, unlike chronic arthritis, cancer grief, or migraines. Nurses consider this in pain management.
The physician has ordered a low-potassium diet for a client with renal failure. Which food should be limited due to its potassium content?
- A. Broccoli
- B. Bananas
- C. Lean beef
- D. White rice
Correct Answer: B
Rationale: Bananas, with ~400-450 mg potassium per fruit, must be limited on a low-potassium diet in renal failure, as impaired kidneys can't excrete excess, risking hyperkalemia broccoli's moderate, beef and rice's low potassium fit better. Nurses teach this, preventing cardiac issues, tailoring diets for renal safety.
When a patient in the terminal stages of lung cancer begins to exhibit loss of consciousness, a major nursing priority is to:

Which of the following statement is NOT true about health care economics?
- A. Affects care delivery
- B. Involves funding
- C. Ignores patient needs
- D. Shapes policy
Correct Answer: C

Which of the following is NOT true about BP?
- A. BP is dependent on blood volume, Cardiac output and peripheral resistance
- B. BP is dependent on age and body weight
- C. The BP on the left arm is higher than the right
- D. BP is taken on the left arm because it is nearest to the heart
Correct Answer: C
Rationale: BP depends on blood volume, cardiac output, and peripheral resistance (A), and varies with age and weight (B), per cardiovascular physiology. The left arm isn't inherently higher (C) it's false; differences are minimal and individual. Left arm use (D) is convention, not proximity (it's not significantly closer). C's absolute claim lacks evidence, making it the untrue statement, as BP symmetry is typical unless pathology exists.
