Question 1 of 5
If a person's breathing and heartbeat stop, brain damage can occur within ______ minutes.
Correct Answer: A
Rationale: The correct answer is A (4-6 minutes) because when breathing and heartbeat stop, the brain is deprived of oxygen. Brain cells start to die within 4-6 minutes without oxygen, leading to irreversible damage. Choice B (8-0 minutes) is incorrect as brain damage occurs much sooner than 8 minutes. Choice C (0-5 minutes) is incorrect because damage starts to occur after 4 minutes. Choice D (5-20 minutes) is incorrect as brain damage can occur within 4-6 minutes, not 20.
Question 2 of 5
In which position is a resident if he is on his left side with his lower arm behind his back and his upper knee flexed?
Correct Answer: A
Rationale: The correct answer is A: Sims'. In Sims' position, the resident lies on the left side with the lower arm behind the back and the upper knee flexed. This position helps prevent pressure ulcers and allows for easier assessment of the rectal area. Prone position (B) is lying face down, Fowler's position (C) is sitting upright at a 45-90 degree angle, and Supine position (D) is lying flat on the back. These positions do not match the description given in the question, making them incorrect choices.
Question 3 of 5
Which of the following is the proper temperature for rinsing and storing dentures?
Correct Answer: B
Rationale: The correct answer is B: Cool. Rinsing and storing dentures in cool water helps prevent warping and damage to the denture material. Warm water may be too hot, potentially altering the shape of the dentures. Hot water can distort the dentures and boiling water can cause irreversible damage by melting the material. Cool water is the safest option for maintaining the integrity of dentures.
Question 4 of 5
Hypertension is
Correct Answer: B
Rationale: The correct answer is B: High blood pressure. Hypertension is defined as the condition where the force of blood against the walls of the arteries is consistently too high. This can lead to serious health issues such as heart disease and stroke. High fever (A) is not the same as hypertension. High pulse rate (C) may be a sign of hypertension, but it is not the same as the condition itself. Low blood pressure (D) is the opposite of hypertension and indicates that the force of blood against the artery walls is too low.
Question 5 of 5
At which angle should residents be positioned for eating?
Correct Answer: D
Rationale: The correct angle for residents to be positioned for eating is 90 degrees. This angle allows for optimal swallowing and digestion, minimizing the risk of choking. Sitting upright at 90 degrees promotes proper alignment of the esophagus and facilitates the movement of food from the mouth to the stomach. Choices A, B, and C are incorrect because lying down flat (180 degrees) can lead to aspiration, while angles greater than 90 degrees may cause difficulties in swallowing and increase the risk of choking. Angle of 90 degrees ensures safe and effective eating posture.
