true
false

Explanation:

• Question 17: Blood pressure measures the force exerted by the blood against the walls of the arteries. It reflects how hard the heart is working to distribute blood. Emotional stress can affect blood pressure but is not what it directly indicates. The presence of infection is usually indicated by symptoms like fever, elevated white blood cell count, etc. The rate and rhythm of the heartbeat is measured by pulse.
• Question 18: A febrile patient (with fever) loses fluids through increased respiration and sweating. Increasing fluid intake helps prevent dehydration. Staying too warm can make the fever worse. Increasing activity when febrile is not advisable as it can further raise body temperature. Decreasing fluid intake is incorrect as fluids are lost during fever.
• Question 19: The mnemonic "lefty loosey, righty tighty" is a common and useful way to remember that turning a valve (or screw, etc.) counter - clockwise (left) opens (loosens) it and turning it clockwise (right) closes (tightens) it.

Answer:

• Question 17: How hard the heart is working to distribute blood
• Question 18: Increase intake of fluids
• Question 19: True
