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. This statement is the most appropriate for an incident occurrence report. It provides a factual, objective description of what was observed without inferring causes or making assumptions about the patient’s actions. Clear documentation is critical in incident reports for accuracy and potential follow-up.
B. This statement includes assumptions about the patient's motivations and actions. It is speculative and not based on direct observation. Incident reports should avoid subjective interpretations and focus on what can be objectively verified.
C. Although this statement describes a potential scenario, it assumes that the patient was walking to the bathroom and that this was the cause of the fall. Since the nurse did not witness the event, this could be misleading and should be avoided in an incident report.
D. While documenting patient statements can be important, this particular comment is subjective and does not provide an objective account of the incident. It could also lead to potential blame without verifying the accuracy of the statement, which could complicate the report.
Correct Answer is B
Explanation
A. Collaboration between nurses at different levels is essential for improving client outcomes. By working together, nurses can share their expertise and ensure that clients receive the best possible care.
B. By increasing delegation between nurses at different levels, RNs can focus on high-risk tasks that require their expertise, while LPNs can take on more routine tasks. This can help to improve efficiency and reduce the workload of RNs, leading to better client outcomes.
C. LPNs can safely and effectively perform many low-risk tasks, such as monitoring vital signs and administering medications. Decreasing their workload for these tasks would not necessarily improve client outcomes.
D. RNs should not be overburdened with high-risk tasks. By delegating appropriate tasks to LPNs, RNs can focus on high-risk tasks that require their expertise and ensure that clients receive the best possible care.
