Which of the following statement best describes blood pressure?
- A. It is the force exerted by the blood against the walls of the blood vessels
- B. The lowest pressure is called systolic pressure
- C. BP is controlled by the sympathetic nervous system alone
- D. BP is measured using sphygmomanometer on the forearm
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.

Mr. Gary moved from hospital to rehab with a care plan. This is an example of?
- A. Care transition
- B. Chronic disease management
- C. Health promotion
- D. Nursing informatics
Correct Answer: A
Rationale: Moving from hospital to rehab with a plan is care transition (A) setting shift, per definition. Management (B) ongoing, promotion (C) preventive, informatics (D) tech not transition-specific. A fits care handoff, making it correct.
Mrs. Mitchell has been given a copy of her diet. The nurse discusses the foods allowed on a 500-mg low sodium diet. These include:
- A. A ham and Swiss cheese sandwich on whole wheat bread
- B. Mashed potatoes and broiled chicken
- C. A tossed salad with oil and vinegar and olives
- D. Chicken bouillon
Correct Answer: B
Rationale: Mashed potatoes and broiled chicken are low in sodium, unlike ham, olives, or bouillon.
Which of the following assessment finding is typical of extracellular fluid loss?
- A. Distended jugular veins
- B. Elevated hematocrit level
- C. Rapid thready pulse
- D. Increased serum sodium level
Correct Answer: C
Rationale: Extracellular fluid loss (e.g., dehydration) reduces blood volume, causing a rapid, thready pulse as the heart compensates for hypovolemia. Distended jugular veins suggest fluid overload, not loss. Elevated hematocrit reflects hemoconcentration, but pulse is a more immediate sign. Increased sodium occurs with water loss, not always fluid volume. Nurses monitor pulse to detect early shock, guiding fluid replacement to restore circulation and prevent organ damage.
Type of respiration that occurs when there is an increase in depth and rate of respiration usually seen in people who engages in strenuous exercise.
- A. Kussmaul's breathing
- B. Eupnea
- C. Hyperpnea
- D. Bradypnea
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.
Which of the following statement best describe incident reporting?
- A. Hiding errors
- B. Reporting adverse events
- C. A patient task
- D. A routine check
Correct Answer: B
Rationale: Incident reporting is reporting adverse events (B), per nursing e.g., falls logged. Not hiding (A), not task (C), not routine (D) safety-focused. B best defines its role, improving Mr. Gary's care safety, making it correct.
