When assessing the blood pressure of a school-aged child, using an adult cuff of normal size will affect the reading and produce a value that is
falsely low
indistinct
accurate
falsely high
The Correct Answer is A
A. Falsely low. Using an adult-sized cuff on a child results in an overestimation of the cuff size, causing the cuff to not inflate properly and distribute less pressure, leading to a falsely low blood pressure reading.
B. Indistinct. The reading may be inaccurate, but it will still produce a numerical value rather than being completely indistinct.
C. Accurate. Accuracy depends on using a cuff size appropriate for the child's arm circumference. An adult cuff on a child is too large, leading to an incorrect reading.
D. Falsely high. A too-small cuff would produce a falsely high reading, but an oversized cuff produces a falsely low blood pressure.

Correct Answer is C
Explanation
A. Remove fans to prevent premature chilling. While preventing rapid cooling is important in some cases, this action is not the priority. The patient’s symptoms suggest heat-related illness, which requires immediate assessment.
B. Apply a hyperthermia blanket to lower temperature slowly. Hyperthermia blankets are typically used in controlled environments for gradual cooling, but first, the patient’s temperature must be assessed to determine the severity of heat-related illness.
C. Take the patient's temperature and vital signs. Confusion and muscle cramps after working in heat suggest possible heat exhaustion or heatstroke, which can be life-threatening. Assessing temperature and vital signs is the priority to determine the severity and guide further treatment.
D. Place the patient in a tub of iced water. Ice water immersion is appropriate for severe heatstroke with a dangerously high core temperature, but cooling measures should only be initiated after confirming hyperthermia with a temperature assessment.
Correct Answer is C
Explanation
A. Regular use of narcotic analgesics leads to drug addiction. While opioids can cause dependence with prolonged use, addiction is characterized by compulsive drug-seeking behavior. When used appropriately for pain management, addiction risk is low.
B. Amount of pain is reflective of actual tissue damage. Pain perception varies widely among individuals. Some may experience severe pain with minimal tissue damage, while others may have little pain despite significant injury.
C. Patients are the best judges of their pain. Pain is subjective, and only the patient can accurately describe its intensity and quality. Nurses should trust the patient's self-report rather than rely solely on appearance or behavior.
D. Chronic pain is psychological in nature. Chronic pain often has a physiological basis, such as nerve damage or inflammation, though psychological factors can influence pain perception. It is not purely psychological.
