Based on your performance on this Optometry Board Part 1 Practice Test, you’re not yet ready for the NBEO® Part 1.
Keep your head up! Also, don’t focus on your estimated score, they mean essentially nothing at the start. Rarely does anyone start these exams and score well immediately, if that was the case then they wouldn’t even need to practice! These are ‘practice’ tests, meaning you’re practicing to improve your skills. If you continue to work hard and study, read and understand the solutions, practice with “OptometryBoards.com” daily and give it your best effort, we promise your score will improve. Review and learn for now, and the scores will come.

Question 2 of 9
2. Question
A 25 years old optometric student has his lung function evaluated through a spirometric exam. The following information is obtained from this exam: Total lung capacity: 6,000 ml., Vital capacity: 4,800 ml., Tidal volume: 500 ml; Residual volume; 1,200 ml. Knowing that his respiratory rate is 14 / minute please determine his minute ventilation.
CorrectD. 7000 ml. 500 x 14=7000 .Minute ventilation = tidal volume x respiratory rate
IncorrectD. 7000 ml. 500 x 14=7000 .Minute ventilation = tidal volume x respiratory rate

Question 3 of 9
3. Question
Angiotensin I,I in combination with the other mechanisms that regulate blood volume / blood pressure is expected to produce which of the following effects on the renal function?
CorrectC. In addition to these arteriolar actions, angiotensin II constricts the mesangial cells, an effect that tends to lower the GFR by decreasing the surface area available for filtration.

4. Question
Which of the following is the major hormone that regulates water loss?
CorrectD. Antidiuretic Hormone (ADH) helps regulate the amount of water in your body. It works to control the amount of water your kidneys reabsorb as they filter out waste from your blood. This hormone is also called arginine vasopressin

6. Question
The mass of tissue localized between the sternum, vertebral column and the lungs is known as.
CorrectD. The mediastinum is a space in the thorax that contains a group of organs, vessels, nerves, lymphatics and their surrounding connective tissue. It lies in the midline of the chest between the pleura of each lung and extends from the sternum to the vertebral column

Question 7 of 9
7. Question
What Skeletal muscle which surrounds the testes and functions to pull the testes closer to the body when cold temperatures are present?
CorrectD. Each cremaster muscle surrounds one of the testicles and its spermatic cord. The muscle helps to move the testicle toward and away from the body to maintain the ideal temperature for sperm production. This is why the scrotum hangs lower in warm conditions and closer to the body in cold weather.

8. Question
If the Buccinator muscle is damaged, then which gland would be impacted?
CorrectC. Parotid gland. The human parotid duct (Stensen’s duct) is a single duct arising from the anterior border of the parotid gland. In adults, the parotid duct is about 6–8 cm long. It crosses the masseter muscle and turns medially at almost a right angle to traverse the buccal fat pad and buccinator muscle.
