Example Question #4 : Standard Tests And Treatments

What is the normal reference range for an adult male hematocrit?

Possible Answers:

Correct answer:

Explanation:

An adult male hematocrit is considered normal when between . Anything below this may indicate anemia, elevated white blood cell count, or blood loss, while numbers above this may indicate dehydration, chronic oxygen deficiency, or a condition of excess red blood cell production (such as polycythemia vera).

Example Question #31 : Procedures

What is considered the normal reference range for an adult female hematocrit?

Possible Answers:

Correct answer:

Explanation:

The normal reference range for an adult female hematocrit is . Anything below this may indicate anemia, elevated white blood cell count, or blood loss, while numbers above this may indicate dehydration, chronic oxygen deficiency, or a condition of excess red blood cell production (such as polycythemia vera).

Example Question #32 : Procedures And Care

A 67-year-old male presents to your clinic with a blood pressure of , temperature is , and heart rate is 82 beats per minute. Blood work shows a cholesterol level of , fasting blood glucose of , and WBC count of .

His history is significant for ST-segment elevation myocardial infarction (STEMI) seven years prior. What, if anything, would you counsel him regarding his vitals and blood work?

Possible Answers:

WBC count is elevated

His cholesterol is too high

Fasting blood glucose is too high

His heart rate is elevated

Correct answer:

His cholesterol is too high

Explanation:

All of his vitals and blood work are within normal range except his cholesterol. Normally, cholesterol is considered within normal range if it is under , but in the case of patients with past history of cardiac event or stroke, cholesterol should be maintained at under

Example Question #32 : Procedures

Which of the following is considered the normal range for platelet count on a complete blood count (CBC)?

Example Question #33 : Procedures

Which of the following values would be considered a normal erythrocyte sedimentation rate (ESR)?

Possible Answers:

Correct answer:

Explanation:

A normal erythrocyte sedimentation rate should be below . Anything above this indicates some sort of inflammatory process.

Example Question #34 : Procedures

Which of the following is considered the normal rage for specific gravity on urinalysis?

Possible Answers:

Correct answer:

Explanation:

While adults may have a specific gravity that ranges anywhere from 1.000 to 1.030, the normal reference range is generally considered to be 1.005 to 1.025. A specific gravity below 1.005 could indicate very dilute urine (the specific gravity of water is 1.000) and anything higher than 1.030 may be present in the case of dehydration, kidney disease, infection, or glucose in the urine.

Example Question #35 : Procedures

Blood pH is maintained by the body in a very close range. What is the normal range for pH of the blood?

Possible Answers:

Correct answer:

Explanation:

The normal range for pH of blood is 7.35 to 7.45. Anything below that range is considered to be acidosis, while values above that range would be considered alkalosis. Recall that the main blood buffer system involves carbonic acid, bicarbonate, and carbon dioxide. The equilibrium equation is as follows:

Example Question #36 : Procedures

Which of the following is not determined by urinalysis? 

Possible Answers:

Specific gravity

Presence of blood

Presence of bacteria

pH

All of these are determined by urinalysis

Correct answer:

All of these are determined by urinalysis

Explanation:

A urinalysis can be an important tool in diagnosis conditions such as the presence of kidney stones, urinary tract infection and even dehydration. A typical urinalysis will contain information on all of the parameters indicated. The presence of glucose, ketones, crystals, casts, and leukocyte esterase may also be included. 

Example Question #36 : Procedures And Care

Washed red blood cells are generally administered to which of the following patient populations? 

Possible Answers:

Patients with metastatic disease

Patients with chronic kidney disease

Patients who are immunocompromised 

Patients with a history of allergic reactions to transfusions 

Correct answer:

Patients with a history of allergic reactions to transfusions 

Explanation:

Washed red blood cells are generally prepared for patients with a history of severe allergic reaction to blood transfusion. Washed red blood cells are not generally required in patients with kidney disease, patient who are immunocompromised, or patients with metastatic disease.
