EXAM QUESTIONS
Q1.
What is the most preferred site for venipuncture?
, CORRECT ANSWER
Median Cubital
RATIONALE
The Median Cubital Vein is the most preferred site for venipuncture because it is
superficial, has a relatively large diameter, and is located in a readily accessible area,
making it easier for healthcare professionals to locate and access, thereby minimizing the
risk of complications. Additionally, the Median Cubital Vein is less susceptible to
compression and has fewer nerve endings, making it a more comfortable and tolerated site
for patients undergoing venipuncture.
Q2.
Prior to preforming the capillary (dermal) puncture the PT should select the
CORRECT ANSWER
Lancet size
RATIONALE
The correct answer is "Lancet size" because it refers to the proper selection of a lancet that
is suitable for the individual's skin type and thickness, ensuring a safe and effective
capillary puncture. Proper lancet size selection is crucial to prevent excessive bleeding,
discomfort, or even injury to the skin, making it a critical step in the pre-puncture process.
Q3.
When collecting blood cultures from an adult patient it is recommended to collect
CORRECT ANSWER
8-10 mL per bottle
RATIONALE
, The recommended 8-10 mL per bottle is to ensure that there is enough sample volume to
detect contaminants or the causative organism, as the current microbiological techniques
have a detection limit that is around 10^4-10^5 CFU/mL. Additionally, using a smaller
volume may result in false-negative results, which can lead to delayed or inappropriate
treatment of a serious infection.
Q4.
Feather edge reflects the correct results for a
CORRECT ANSWER
Peripheral Blood Smear
RATIONALE
A feather edge refers to the appearance of certain blood cells in a Peripheral Blood Smear
when their borders are not clearly defined, resembling a feather. This phenomenon occurs
due to the way the cells' membranes are distorted, making the feather edge a characteristic
observation in a Peripheral Blood Smear examination.
Q5.
What tests require fasting
CORRECT ANSWER
Glucose, triglycerides, cholesterol, vitamin & mineral problems and pregnancy
RATIONALE
This answer is correct because fasting is necessary to accurately measure glucose,
triglycerides, and cholesterol levels in the blood, as non-fasting conditions can artificially
elevate these readings due to recent food consumption. Additionally, fasting tests for
these substances avoid confounding factors that can affect results, ensuring a more
, reliable assessment of an individual's metabolic health, which is crucial for pregnant
individuals due to the unique physiological changes and requirements of pregnancy.
Q6.
When entering a patients room you should
CORRECT ANSWER
introduce yourself and explain procedure
RATIONALE
When entering a patient's room, you should introduce yourself and explain the procedure
to establish a sense of trust and respect, as well as to inform the patient of what to expect,
thereby reducing anxiety and promoting a positive experience. This approach also helps to
ensure that the patient understands the purpose of the interaction and can provide
informed consent or ask questions if necessary.
Q7.
What two factors that determine weather a child should have capillary collection by
heel or stick?
CORRECT ANSWER
Age & developmental factors
RATIONALE
Age is a key factor because it affects the thickness of a child's skin, with younger children
having thinner skin that is more susceptible to damage from a lancet, making heel prick a
safer option. Developmental factors, such as cooperation and ability to stay still, also play a
