Question 1 - PADI Open Water Diver Manual Answers Chapter 3
1. One way to avoid disorientation while descending and ascending is to:
Answer: C - follow a reference.
Descending and ascending with a reference is always recommend, especially for beginner divers. A reference can be a line, sloping bottom, wall, or pinnacle.
Answer: C - follow a reference.
Descending and ascending with a reference is always recommend, especially for beginner divers. A reference can be a line, sloping bottom, wall, or pinnacle.
A reference can guide you to the dive site which is great in low visibility. Even better is that a reference gives you a sense of direction and tells you which way is up or down. This greatly helps to avoid disorientation underwater.
Question 2 - PADI Open Water Diver Manual Answers Chapter 3
2. My buddy and I are diving from a boat and there’s a mild current. In most circumstances, we would ___________ for the first part of the dive.
Answer: A - swim into the current
Diving in a mild current is ok and mild currents are common. We recommend that you start your dive swimming against a mild current as you have more energy at the beginning of the dive.
When you turn back you will go with the current back to your starting point, which is easier and you will conserve more air for the way back.

Question 3 - PADI Open Water Knowledge Review 3 Answers
3. My buddy and I get disoriented while boat diving. There is a mild current, and we surface away from the boat. We should___________. If unable to reach the boat or too tired, we should _____________.
Answer: B - Swim across the current to reach the trail line, become buoyant and signal the boat to pick us up.
It is easier to swim across a current than against it. This way you can still move closer to the boat without overexerting yourself.
Answer: B - Swim across the current to reach the trail line, become buoyant and signal the boat to pick us up.
It is easier to swim across a current than against it. This way you can still move closer to the boat without overexerting yourself.
Behind the boat will be a trail line, which is a line with a buoy attached in the end. Try and grab that line and pull yourself towards the boat or the boat staff will pull you in. In the unlikely event, the current is too strong, you can signal the boat for help and they will pick you up.
Question 4 - PADI Open Water Diver Manual Answers Chapter 3
4. My buddy and I remain neutrally buoyant and stay above the bottom enough to avoid contact. We do this because bottom contact:
Answer: A, B, and C
We must never touch the bottom as it can damage the marine life, you can stir up the bottom and you might get injured.
Answer: A, B, and C
- may injure or kill fragile aquatic life.
- tends to disturb the bottom and reduce the visibility.
- increases the risk of accidental cuts, scrapes, or stings.
We must never touch the bottom as it can damage the marine life, you can stir up the bottom and you might get injured.
On the other hand, if you are too far away you won’t see anything. The trick is to find the perfect distance from the bottom, so we don’t touch it but still get close enough to enjoy the marine life.
To do this you need to learn to control your buoyancy and you will practice this during the PADI Open Water Diver course skills. On top of that the more you scuba dive, the better your buoyancy will become.

Question 5 - PADI Open Water Diver Manual Answers Chapter 3
5. When assessing conditions, if there is anything that causes me significant anxiety or concern, if I can’t address it, I should not dive. Ultimately, I am responsible for my own safety, so only I can make the final decision to dive.
Answer: TRUE
Being nervous before the dive is more common than you think and many beginners and sometimes experienced divers feel this.
If you experience significant anxiety before the dive then please let your buddy, Divemaster, and your Dive Instructor know before the dive. Then discuss if you should continue or take a break from diving until you feel confident again.
Answer: TRUE

If you experience significant anxiety before the dive then please let your buddy, Divemaster, and your Dive Instructor know before the dive. Then discuss if you should continue or take a break from diving until you feel confident again.
It is important to never feel ashamed about this and don’t let anyone pressure you into diving. In the end, it is your life, and don’t forget scuba diving is supposed to be fun.
Trying to scuba dive with significant anxiety can get you in a lot of trouble, so be honest to yourself.
Just remember that during your PADI Open Water Diver course you will learn scuba diving in small steps to build confidence and you will never be thrown into the deep end on your first experience. But if your anxiety is too much then you should talk to your instructor and cancel the dive.

Question 7 - PADI Open Water Diver Manual Answers Chapter 3
7. Risks of diving beyond my training and experience limits include that:
Answer: A, B, and C
Some risks and hazards are not always obvious to the untrained eye. Some types of currents, marine life, tides, and other hazards are not always easy to identify. This can lead to a false sense of security or increases your anxiety levels. Feeling nervous or anxious can cloud your judgment and reaction speed.
You can solve this by taking more specialized dive training, have an experienced certified dive leader with you on a dive, or just choose to cancel the dive and plan another easier dive.
Answer: A, B, and C
- in some forms of diving, the hazards are not obvious.
- it can cause me to have a false sense of security.
- anxiety from doing so can distract me from noticing other problems.

Question 8 - PADI Open Water Diver Manual Answers Chapter 3
8. While planning a shore dive, my dive buddy says it will be “no problem” diving in high surf that I’ve never been trained in nor have experience with. Looking at the surf, I don’t think I am prepared for diving in it. My best response is to:
Answer: C - politely refuse to dive and suggest an alternate location with no significant surf.
Too many people feel the pressure to follow other people's opinions, but in the end, it is your life at stake. Never let anyone pressure you in participating in a dive that you are not comfortable with.
Just ask them to change the dive plan to something that you feel good with and if someone keeps pushing you, then cancel everything and find a new dive buddy or leader. Scuba diving is supposed to be fun and safe. There is no room for ego in the scuba dive community.

Question 9 - PADI Open Water Knowledge Review 3 Answers
9. To prevent and/or handle injuries caused by aquatic life, I should:
Answer: B, C, D, D, E, and F
Being familiar with potentially hazardous animals can help you identify them easier. Never touch anything underwater, even if you are convinced the animal is harmless. Not only is it bad for the animal to disturb them, but many dangerous marine species are camouflaged or imitate the looks of a harmless animal.
Answer: B, C, D, D, E, and F
- watch where I put my feet, hands, and knees.
- wear an exposure suit.
- treat all organisms with respect.
- be familiar with potentially hazardous animals where I’m diving.
- be prepared to provide first aid for aquatic life injuries.
Being familiar with potentially hazardous animals can help you identify them easier. Never touch anything underwater, even if you are convinced the animal is harmless. Not only is it bad for the animal to disturb them, but many dangerous marine species are camouflaged or imitate the looks of a harmless animal.
Try mastering your buoyancy before diving over the reef to prevent accidentally touching it. Practice this over a sandy bottom during your first dives.
Wearing an export suit can help you prevent cuts and stings if you accidentally touch dangerous marine life. Some divers wear gloves to be able to touch marine species. This is very bad and you should never touch anything while scuba diving.
Make sure you have a first aid kit on the boat or/and on land to treat injuries in the unlikely event you do get stung or receive a cut. Then always check with a physician afterward.
Certified Rescue Divers, EFR, Divemasters, and Diving Instructors are trained to provide basic first aid, but they are not doctors and for this reason, you should always let a licensed physician look at any dive-related injury.

Question 10 - PADI Open Water Diver Manual Answers Chapter 3
10. My buddy and I accidentally find ourselves in a rip current. There are no special, local procedures, so we follow the generally recommended action of
Answer: D - inflating our BCDs and swimming parallel to shore.
A rip current is hard to recognize with an untrained eye. They can be tricky to deal with and potentially dangerous. Rip currents are usually too strong to swim against.
We recommend you swim parallel to the rip current towards the shore. Make sure you always fully inflate your BCD when you are at the surface. In case the rip current is too strong you should signal for help and stay close to your buddy.
A local orientation can help in preventing getting catch in a rip current in the first place by not diving in areas know for rip currents.

Question 12 - PADI Open Water Knowledge Review 3 Answers
12. When boarding a dive boat, the divemaster asks me to fill my name in on the roll. The reason for this is to:
Answer: D - make sure everyone’s aboard after each dive.
A boat master which can be a certified Divemaster or Scuba Diving Instructor will stay on the boat looking after surface logistics and your safety.
To make sure that everyone is back on the boat before leaving the dive site, they use a dive roster to track the divers. It is common that you fill this in before and after the dive and confirm that you entered and exit the water.

Question 15 - PADI Open Water Knowledge Review 3 Answers
15. My buddy and I are diving from a boat in mild to moderate current. There is a line from the back of the boat where we’ll enter, which leads to the mooring line at the front of the boat. The purpose of the line leading to the mooring line is to:
Answer: D - let us pull ourselves to the mooring line.
It can be hard to swim against a mild to moderate current on the surface to the descent line. Even if you are a strong swimmer it can take a lot of energy and you might get overexerted before the dive. This can lead to stress or bad air consumption during the dive.
Using is line from the back of the boat to the descent line can help you to stay relaxed and conserve energy before descending.

18. At the surface, I have a problem. If I have not already done so, the first thing I should do is:
Answer: A - make myself buoyant (inflate BCD and/or drop weights).
The first thing you should always do when reaching the surface is to fully inflate your BCD to become positively buoyant.
Answer: A - make myself buoyant (inflate BCD and/or drop weights).
The first thing you should always do when reaching the surface is to fully inflate your BCD to become positively buoyant.
Especially in an emergency, you want to be as positively buoyant as possible, so besides fully inflating your BCD you should also drop your weight belt or integrated weight system.
Question 19 - PADI Open Water Diver Manual Answers Chapter 3
19. A diver at the surface begins to struggle. He has wide, unseeing eyes and he has pushed off his mask. His BCD isn’t inflated and he doesn’t inflate it when the divemaster calls for him to do so. This diver is _______________. To help, I should first ______________.
Answer: D - out of control; make myself and the diver buoyant (inflate BCD/drop weights).
A panicked diver at the surface usually does not respond well. It is therefore important to make sure they are positively buoyant by inflating their BCD and dropping the weight system.
Answer: D - out of control; make myself and the diver buoyant (inflate BCD/drop weights).
A panicked diver at the surface usually does not respond well. It is therefore important to make sure they are positively buoyant by inflating their BCD and dropping the weight system.
Don’t forget to also inflate your BCD and drop your weight system to assist an out-of-control panic diver better. In the PADI Rescue Diver course you will learn more techniques to deal with this situation, so ask your instructor for more information on how to join this potentially life-saving course.
Question 20 - PADI Open Water Diver Manual Answers Chapter 3
20. With an unresponsive diver underwater, the primary concern is___________. Once at the surface, besides establishing buoyancy and calling for help, the primary concern is ________________.
Answer: B - getting the victim to the surface, checking for breathing, and providing rescue breaths if the victim isn’t breathing.
It is rare, but in the unlikely event, you might encounter an unresponsive diver underwater you should first get the victim to the surface.
Answer: B - getting the victim to the surface, checking for breathing, and providing rescue breaths if the victim isn’t breathing.
It is rare, but in the unlikely event, you might encounter an unresponsive diver underwater you should first get the victim to the surface.
At the surface establish positive buoyancy for you and the victim and check for breathing. If the diver is not breathing you should start rescue breaths while towing the non-breathing diver to the boat or shore.
