1. What is the appropriate needle size for insulin injection?

• A. 18G, 1 ½” long
• B. 22G, 1” long
• C. 22G, 1 ½” long
• D. 25G, 5/8” long

Correct answer: D

Rationale: The appropriate needle size for insulin injection is 25G, 5/8” long. This size allows for accurate and comfortable insulin administration in subcutaneous tissue.

2. What is the appropriate route of administration for insulin?

• A. Intramuscular
• B. Intradermal
• C. Subcutaneous
• D. Intravenous

Correct answer: C

Rationale: The appropriate route of administration for insulin is subcutaneous. Subcutaneous injections are commonly used for insulin administration due to the slower absorption rate compared to intramuscular or intravenous routes. This slower absorption rate allows for better control of blood glucose levels. Intramuscular administration is not ideal for insulin as it can lead to rapid absorption and fluctuations in blood sugar levels. Intradermal injections are shallow and used for skin testing rather than insulin administration. Intravenous administration of insulin is not recommended due to the rapid and unpredictable effects it can have on blood glucose levels.

3. Which of the following is not a cause of tachycardia?

• A. Fever
• B. Exercise
• C. Sympathetic nervous system stimulation
• D. Parasympathetic nervous system stimulation

Correct answer: D

Rationale: Tachycardia is an increased heart rate, and it can be caused by various factors such as fever, exercise, and sympathetic nervous system stimulation, all of which tend to increase heart rate. However, parasympathetic nervous system stimulation typically slows the heart rate, making it the exception among the choices provided. Thus, parasympathetic nervous system stimulation is not a cause of tachycardia.

4. In which of the following organs does the exchange of gases take place?

• A. Kidneys
• B. Lungs
• C. Liver
• D. Heart

Correct answer: B

Rationale: The exchange of gases, specifically oxygen and carbon dioxide, occurs in the lungs. In the lungs, oxygen from the air we breathe enters the bloodstream, while carbon dioxide is removed from the bloodstream and exhaled. This process is essential for respiration and supplying the body with oxygen for energy production. The kidneys filter waste from the blood to produce urine and regulate fluid balance (Choice A). The liver is involved in detoxification, protein synthesis, and producing bile (Choice C). The heart is responsible for pumping blood throughout the body to deliver oxygen and nutrients (Choice D).

5. For a rectal examination, the patient can be directed to assume which of the following positions?

• A. Genupectoral
• B. Sims
• C. Horizontal recumbent
• D. All of the above

Correct answer: B

Rationale: The correct position for a rectal examination is the Sims position, where the patient lies on their left side with the upper knee flexed. This position allows for easy access and visualization of the rectal area for examination.
