Which of the following lancet positions should a phlebotomist recognize as part of the aseptic technique protocol?
Perpendicular to the fingerprint grooves
Parallel to the nail bed
Along the lateral portion of the first digit
Along the medial portion of the fifth digit
The Correct Answer is A
Choice A reason:
When performing a capillary blood collection, such as a fingerstick, the lancet should be positioned perpendicular to the fingerprint grooves. This orientation helps to ensure that the incision is made across the ridges of the fingerprint, which can facilitate a better blood flow and make it easier to collect an adequate sample without needing to squeeze the finger excessively, which could hemolyze the sample.
Choice B reason:
Positioning the lancet parallel to the nail bed is not recommended because it can result in a cut that runs along the length of the fingerprint grooves, which may not bleed as freely and could also be more painful for the patient.
Choice C reason:
Using the lancet along the lateral portion of the first digit is not part of the standard aseptic technique protocol for capillary blood collection. The first digit, or thumb, has a pulse and should generally be avoided because it can be more sensitive and is more prone to bruising.
Choice D reason:
The medial portion of the fifth digit, or the little finger, is also not a recommended site for capillary blood collection with a lancet. The little finger is typically smaller and may not provide an adequate site for blood collection, and similar to the thumb, it can be more sensitive and prone to injury.

Correct Answer is A
Explanation
Choice A Reason:
When a patient is under "Contact Precautions," it is recommended that healthcare workers don a gown upon entering the patient's room. This is to prevent the spread of infection through contact with the patient or their environment. The gown should be removed before leaving the room to avoid contaminating other areas.
Choice B Reason:
While a face shield may be necessary for certain procedures, it is not specifically required for "Contact Precautions." The primary concern with contact precautions is preventing the transmission of infections through touch, not through droplets, which is what a face shield would protect against.
Choice C Reason:
Donning a mask is not a standard requirement for "Contact Precautions" unless there is a risk of droplet transmission. In this scenario, the precautions are specifically for contact, and therefore, a mask alone would not be sufficient.
Choice D Reason:
Gloves should be donned before any potential contact with the patient or their immediate environment, not just after cleaning and evaluating the venipuncture site. Gloves are a critical component of PPE when dealing with patients under "Contact Precautions."
Correct Answer is A
Explanation
Choice A Reason:
The supine position, where the patient lies flat on their back with the face upward, is the correct position for initiating CPR. This position allows for proper chest compressions and airway management, which are critical components of CPR.
Choice B Reason:
The Semi-Fowler's position, where the patient is partially sitting up with the head of the bed raised to 30-45 degrees, is not suitable for CPR. This position would make it difficult to perform effective chest compressions.
Choice C Reason:
The prone position, where the patient lies flat on their stomach, is not appropriate for CPR. Chest compressions cannot be effectively delivered in this position, and it would also complicate airway management.
Choice D Reason:
The side-lying position is not appropriate for CPR. While this position can be used for an unconscious patient who is breathing normally to maintain an open airway and prevent aspiration, it is not suitable for CPR, which requires the patient to be on their back.
