Which term best describes sickle cell disease?
autosomal recessive disorder
X-linked genetic disorder
autosomal dominant disorder
inherited disorder
The Correct Answer is A
A. Sickle cell disease is classified as an autosomal recessive disorder. This means that a child must inherit two copies of the mutated gene (one from each parent) to express the disease. Individuals with one normal and one mutated gene are carriers (sickle cell trait) but do not exhibit symptoms.
B. X-linked genetic disorders are caused by mutations on the X chromosome and typically affect males more severely than females, as males have only one X chromosome. Sickle cell disease is not located on the X chromosome; therefore, it is not classified as X-linked.
C. In an autosomal dominant disorder, only one copy of the mutated gene is needed for an individual to express the disease. Sickle cell disease does not follow this inheritance pattern; it requires two copies of the mutated gene, which makes this classification inaccurate.
D. While sickle cell disease is indeed an inherited disorder, this term is broad and could apply to many genetic conditions. It describes the general nature of the disease but does not provide the specificity that "autosomal recessive disorder" does.

Correct Answer is A
Explanation
A. Disinfecting equipment is a routine infection control measure that UAPs can perform after receiving proper training on the protocol. This activity does not require clinical judgment and falls within the
UAP’s responsibilities.
B. While UAPs may assist in educating visitors about hand hygiene, the demonstration of correct hand washing techniques is typically a nursing responsibility. Nurses are trained to provide this education effectively and ensure that the information is conveyed appropriately, especially since it may involve assessing visitors’ understanding.
C. This task requires clinical judgment and assessment skills, which are within the nursing scope of practice. Nurses need to evaluate this information in the context of the client’s overall health and care plan, making it inappropriate for delegation to UAP.
D. Screening for symptoms involves assessment and interpretation, which require a nursing level of knowledge and clinical judgment. While UAPs may collect basic data or report observations, actively screening clients for specific symptoms should be performed by a nurse.
Correct Answer is D
Explanation
A. While it is important to address concerns about impairment, confronting the nurse directly can be counterproductive and may escalate the situation. It is essential to approach the situation with caution and follow established protocols for dealing with suspected substance impairment.
B. While gathering observations from colleagues may seem reasonable, it can create a culture of gossip and may violate confidentiality. This approach can also lead to misinformation and should not be the first step in addressing a serious concern about a colleague's safety and well-being.
C. Documenting observations is important, but it should not be the sole action taken at this point. Communicating with the personnel department is part of the process if the situation escalates, but immediate action is necessary to ensure patient safety.
D. This option is the most appropriate initial action. By closely monitoring the nurse’s behavior, the manager can gather more information before taking further steps. This approach allows for the collection of objective data and ensures patient safety while avoiding premature accusations.
