We also know that everyone likes to study differently, so we offer three different ways to use your DOH Laboratory Assistant practice exams:

  • Timed DOH Lab Assistant Practice Test Mode: Timed tests are just like the DOH Lab Assistant exam. Our system sets the test time to the same time limit, or time limit per question, that you will experience with the actual exam on test day. This is a great method of practicing your pacing, especially if you're concerned about completing your exam within the time limit.

  • Untimed DOH Laboratory Assistant Practice Test Mode: With this option, you can take your time and thoroughly consider each question before answering. This rush-free mode is recommended for those dipping their toes into exam prep or just starting on their journey to take the DOH Lab Assistant . It is a great way to test your knowledge with no time limit and highlight blind spots you will need to come back to in your studies - one of the many advantages of taking DOH Lab Assistant practice exams with Exam Edge!

The questions act as a study guide, giving you the option to see the answers as you take the test. Study guide mode is an effective way to review the DOH Lab Assistant exam subject matter before you take the exam in a timed format. We recommend taking a practice test in explanation mode and taking thorough notes as the best method for beginning your test prep.

DOH Laboratory Assistant - Features Sample Questions

Which of these drugs is classified as an Aminoglycoside?

Correct Answer:
amikacin.


the question asks to identify which among the listed drugs is classified as an aminoglycoside. ikacin.

aminoglycosides are a class of antibiotics used primarily to treat bacterial infections. they work by binding to the bacterial 30s ribosomal subunit, causing misreading of mrna and inhibiting protein synthesis, which ultimately leads to bacterial cell death. these antibiotics are particularly effective against aerobic gram-negative bacteria and are often used in severe infections when other antibiotics may not be effective.

amikacin, specifically, is a semi-synthetic derivative of kanamycin, another aminoglycoside. it is often used in clinical settings for treating various infections caused by aerobic gram-negative bacteria, and it is also effective against certain gram-positive bacteria. amikacin is reserved for more severe infections, particularly those that are resistant to other less potent antibiotics.

the other drugs listed in the options each belong to different classes of antibiotics or drugs: - herbimycin is classified as an ansamycin, which is known for its antitumor properties and activity against bacteria, including inhibiting protein kinases. - cilastatin is not an antibiotic itself but is combined with imipenem (a carbapenem antibiotic) to inhibit the renal dehydropeptidase enzyme. this inhibition prevents the degradation of imipenem in the kidneys, thus increasing its efficacy. - cefazolin is a first-generation cephalosporin, which is another class of beta-lactam antibiotics used to treat bacterial infections by inhibiting cell wall synthesis.

therefore, the only drug among the options that is classified as an aminoglycoside is amikacin. the other drugs listed are from different classes and have distinct mechanisms of action and clinical uses.

The drawing above depicts which of the following?

Correct Answer:
urinometer


the drawing in question accurately represents a urinometer, which is a specialized instrument used primarily in the medical and laboratory settings to measure the specific gravity of urine. this measurement is crucial as it provides insights into the hydration status of the body and can help in diagnosing various health conditions.

a urinometer functions by the principle of buoyancy and displacement. it consists of a glass or plastic tube with a weighted bulb at one end to ensure it floats upright. the stem of the urinometer is marked with a graduated scale which is calibrated to read the specific gravity of the fluid in which it is placed. when the urinometer is placed in a sample of urine, it floats to a level dependent on the density of the urine. the specific gravity is then read directly from the scale at the liquid's surface level.

specific gravity is a dimensionless quantity that is a measure of the ratio of the density of the substance to the density of water at a specified temperature. for urine, a normal specific gravity range is typically from 1.010 to 1.030. values outside this range might suggest conditions such as dehydration, overhydration, and disorders affecting kidney function.

it is important to distinguish a urinometer from similar-looking devices such as refractometers or mass gravity meters: - a refractometer is used to measure the degree to which light changes direction (refracts) as it passes through a liquid, which can also be indicative of specific gravity but is a completely different method of measurement. - a mass gravity meter, often used in industrial contexts, measures the gravity or gravitational pull on a mass, which is unrelated to the task of measuring urine specific gravity.

therefore, understanding the specific function and design of a urinometer helps in accurately interpreting the drawing and utilizing the urinometer correctly in practical scenarios. this knowledge is particularly relevant in fields like healthcare, where such measurements are often critical for patient diagnosis and management.
