PE 28G final exam

For people who are going for a certification as Red Cross certified swim teachers, there is a multiple choice Red Cross exam. The study guide for it is at: Water Safety Instructor exam study guide.

The other exam is the De Anza College final exam. Questions for it will be posted here as we go along.

1) When should you clear the water during a lightning storm?

Correct answer: Clear everyone from the water at the first sound of thunder or sight of lightning.

2) If you clear the water during a lightning storm, when should you let people back in to swim?

Correct answer: Wait 30 minutes after the last sound of thunder or sight of lightning to resume activities.

Wrong answer: After the storm has cleared. (What does that mean? After the rain/wind are over? After the clouds have left the sky?)

3) Describe two other weather related situations when you would need to clear the pool because you can't see your swim students.

answers: when the 'fog' is so thick you can't see your swim students/team (most likely in early morning swim)

when it is raining so hard you can't see below the surface

4) List three of the four reasons people should not hang on lanes lines. Extra credit for all four.

Here are the four reasons:

They are expensive and they break.

It makes the lifeguard think you are in trouble.

If a bunch of people hang out on a laneline there is no room left for someone who really is in trouble to grab the line.

Especially if the lane line is at the boundary of, for example, a lake swim area, it submerges it so others can't see the boundary.

5) What is the minimum safe depth to teach dives from the side of the pool?

answer: 9 feet

6) What is the minimum safe depth under a one meter diving board?

answer: 11 1/2 feet

7) You will have an essay question in which you will need to describe to a swim student how to 'clear' their ears.

The lifeguard text describes "EQUALIZING PRESSURE UNDERWATER: Note the addition at step 2 in italics. If you do not tell a swimmer not to let any air out they might think they are restricting air flow rather than stopping it and it might not work when they try to do it.

As you descend into deep water, water pressure increases and presses against the empty spaces in your skull, especially those inside your ears. This can cause pain or even injury. To relieve this pressure, you need to force more air into the empty spaces so that the air pressure matches the water pressure. This is called 'equalizing.' Be sure that you equalize early and often by taking the following steps:

1. Place your thumb and finger on your nose or on the nosepiece of your mask if you are wearing one.

2. Pinch your nose and keep your mouth shut. Try to exhale gently through your nose" (but don't let any air out) "until the pressure is relieved.

3. Repeat this as needed to relieve ear pressure. If your ears hurt, do not attempt to go deeper until successfully equalizing the pressure.

4. If you are using a mask when descending, the increased water pressure will cause the mask to squeeze your face. To relieve the squeezing, exhale a small amount of air through your nose into the mask.

If you are unable to equalize the pressure because of a head cold or sinus problem, you should return to the surface rather than risk an injury."

8) How would a swimmer be likely to get head lice at a pool?

9) Are swim diapers effective in holding in feces? Why or why not?

10) A large pool, (over 300 linear feet of pool wall, for example, the big pool at De Anza), must have how many accessible means of entry for disabled persons?

11) Briefly describe three kinds/designs of accessible means of entry.

12) Adults in general at pools do interact with kids. Many adults at pools are not 'suspicious'; they are used to caring for their own children and helping kids who need assistance or playing with kids who are playing with their own children. But at a pool a suspicious person might include adults who are not the parent of a child who attempt to interact with the child and get close to them by playing games, who bump into kids in the pool or photograph kids. Describe three other activities/contacts by adults with children that could be suspicious (from the class reading).

13) true/ false A sunscreen with a rating of SPF 45 gives you three times as much protection as one with a rating of SPF 15.

14) According to the Santa Clara County Department of Public Health, at a pool (other than a spa pool) the occupant capacity shall be based on one bather for every ________ square feet of pool water surface area.

15) According to the Santa Clara County Department of Public Health, water in a wading pool must be clear enough that _________ can be seen at all times.

16) In your Water Safety Instructor's Manual there are safety notes in boxes throughout the text, such as the one on page 103 in the section on hearing impairment that says "Establish clear gestures for emergencies. Use printed material to add to verbal information related to safety." Describe three other safety notes.

17) Give two reasons to not allow water wings or other inflatable arm bands at your pool.

18) List three water safety topics (for example: How to call for help and the importance of knowing First aid and CPR) from any level of swim program.

Extra credit for up to seven.

19) To help prevent hyponatremia, do not let young children submerge more than ____ times in a lesson during the initial learning phase.

Extra credit for a good description of hyponatremia

20) Which swim level includes a 500 yard swim in the exit skills assessment?

21) The most difficult exit skills assessment in Preschool Aquatics is:

a) 5 body lengths of swimming

b) a 15 yard swim

c) there is no actual swim distance in any exit skills assessment in Preschool Aquatics

22) Can we drownproof children? Why or why not?
