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 C
Explanation
A. While this situation raises ethical considerations, particularly regarding adolescent confidentiality, the nurse is not justified in overriding the client's right to confidentiality solely based on the request. In many jurisdictions, minors may have the right to confidentiality about reproductive health issues, though this can vary.
B. The nurse is generally required to respect this client's confidentiality. Unless there is a specific safety concern (e.g., domestic violence), the nurse should honor the client's request to keep this information private. Confidentiality should be upheld unless there is a clear and immediate risk of harm.
C. In this situation, the nurse may be justified in overriding the client’s confidentiality due to the disclosure of potential abuse. Healthcare professionals are often mandated reporters in cases of suspected abuse or neglect, particularly involving vulnerable populations such as older adults. The nurse has a duty to report this situation to ensure the safety of the client.
D. A client's wish not to know their diagnostic results does not justify overriding their confidentiality. The nurse must respect the client’s autonomy and decision-making regarding their own health information. The nurse should provide support and discuss the implications of this decision but should not disclose the results without the client’s consent.
