NurseDive Free Nursing Practice Question
Every state in the U.S. requires that newborns be tested for which of the following disorders?
A. Septicemia
Septicemia, also known as sepsis, is a serious bloodstream infection that can be life-threatening. It is not a disorder that is screened for at birth because it is not a congenital condition but rather an infection that can occur at any time when bacteria enter the bloodstream.
B. Bacteremia
Bacteremia refers to the presence of bacteria in the bloodstream and, like septicemia, is not a congenital disorder. It is not typically screened for at birth as it is an acquired condition that can occur after exposure to bacteria.
C. Phenylketonuria
Phenylketonuria (PKU) is a genetic disorder that results in an inability to metabolize the amino acid phenylalanine. Untreated, PKU can lead to intellectual disability, seizures, and other serious health problems. Newborn screening for PKU is required in every state in the U.S. because early detection and dietary treatment can prevent the severe consequences of the disorder.
D. Proteinuria
Proteinuria is the presence of abnormal amounts of protein in the urine, which can be a sign of kidney disease. It is not a condition that is screened for at birth as part of the standard newborn screening panel.

Full Explanation
Choice A reason:
Septicemia, also known as sepsis, is a serious bloodstream infection that can be life-threatening. It is not a disorder that is screened for at birth because it is not a congenital condition but rather an infection that can occur at any time when bacteria enter the bloodstream.

Choice C reason:
Phenylketonuria (PKU) is a genetic disorder that results in an inability to metabolize the amino acid phenylalanine. Untreated, PKU can lead to intellectual disability, seizures, and other serious health problems. Newborn screening for PKU is required in every state in the U.S. because early detection and dietary treatment can prevent the severe consequences of the disorder.

Similar Questions
A phlebotomist should explain the procedure prior to venipuncture to:
A. Maintain compliance with CLIA standards.
While maintaining compliance with Clinical Laboratory Improvement Amendments (CLIA) standards is important, it is not the primary reason for explaining the venipuncture procedure to the patient. CLIA standards primarily deal with laboratory testing and do not specifically require the explanation of procedures to patients.
B. Evaluate the patient's understanding.
Evaluating the patient's understanding is a beneficial practice as it ensures that the patient is informed and can participate in their own care. However, it is not the primary legal or ethical requirement for explaining the procedure.
C. Maintain compliance with OSHA standards.
Maintaining compliance with Occupational Safety and Health Administration (OSHA) standards is crucial for ensuring the safety of both the healthcare provider and the patient. OSHA standards require that certain safety protocols be followed, but they do not specifically mandate that the procedure be explained to the patient for the purpose of obtaining consent.
D. Obtain the patient's consent.
Obtaining the patient's consent is the primary reason a phlebotomist should explain the procedure prior to venipuncture. Informed consent is a fundamental ethical and legal principle in healthcare. It involves informing the patient about the procedure, its risks, benefits, and alternatives, and ensuring that the patient understands this information before agreeing to proceed. This process respects the patient's autonomy and right to make decisions about their own healthcare.

When performing a blood smear, which of the following actions should a phlebotomist take to ensure a quality result?
A. Hold the two slides at 90 degrees to each other when performing the smear.
Holding the two slides at a 90-degree angle is not the correct technique for performing a blood smear. This angle is too steep and would not allow the blood to spread thinly across the slide, which is necessary for creating a quality smear that can be examined under a microscope.
B. Allow the blood drop to clot slightly prior to performing the smear.
Allowing the blood drop to clot slightly before performing the smear is not advisable. Clotting can interfere with the spread of the blood and the formation of a monolayer, which is essential for accurate microscopic examination. The blood should be fresh and anticoagulated to prevent clotting.
C. Hold the slides at 30 degrees to each other when performing the smear.
Holding the slides at a 30-degree angle is the correct technique for performing a blood smear. This angle allows the spreader slide to push the blood drop smoothly across the patient slide, creating a thin, even layer of blood that is ideal for microscopic analysis. The angle, speed, and pressure must be consistent to achieve a quality smear.
D. Allow the blood drop to clot completely prior to performing the smear.
Allowing the blood drop to clot completely before performing the smear would make it impossible to create a smear. Clotted blood cannot be spread into a thin layer, which is necessary for microscopic examination of the blood cells.

A phlebotomist needs to collect a PT (Prothrombin Time) from a patient with a difficult vein. Which of the following is the best tube for the draw?
A. Light green
The light green tube typically contains lithium heparin and is used for plasma determinations in chemistry. It is not suitable for coagulation studies, such as PT, because heparin is an anticoagulant that would interfere with the test results.
B. Lavender
The lavender tube contains EDTA, which is an anticoagulant that binds calcium. While it is commonly used for complete blood counts (CBC) and other hematology tests, it is not appropriate for coagulation studies because the binding of calcium would affect the clotting process required for a PT test.
C. Royal blue
The royal blue tube can come with different additives or be additive-free, depending on the color of the closure. It is primarily used for trace element testing, toxicology, and nutrient determinations. The additives in a royal blue tube could potentially contaminate the sample and interfere with the PT test.
D. Light blue
The light blue tube contains sodium citrate, which is the appropriate anticoagulant for coagulation studies like PT. Sodium citrate works by binding calcium in the blood, preventing clotting. The PT test measures the time it takes for a clot to form after re-calcification, making the light blue tube the correct choice for this test.
