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. In many institutions, when a nurse administers a controlled substance and has leftover medication, it is standard practice to have another nurse witness the disposal of the excess. This is a safeguard against misuse and ensures accountability.
B. While a sharps container is appropriate for disposing of needles and other sharp objects, it is not suitable for liquid medications. Discarding liquid medications in a sharps container could lead to contamination and is not compliant with disposal protocols.
C. Medications, especially controlled substances, should never be saved for later use once they have been drawn up or prepared. This practice poses a significant risk for medication errors and misuse.
D. Generally, the waste amount is not sent to the pharmacy. Instead, it should be wasted according to the facility's policy, typically in the presence of another nurse. Sending it to the pharmacy is unnecessary and could create logistical complications.
Correct Answer is B
Explanation
A. This response dismisses the client’s immediate needs and does not offer a supportive or constructive solution. It puts the responsibility on the client without addressing her request for assistance or exploring alternatives.
B. This is an appropriate and constructive response. It acknowledges the client’s situation and shows willingness to help find alternative resources, such as community services, meal delivery programs, or assistance from family or friends. This approach empowers the client and provides practical support.
C. While this response expresses willingness to help, it goes against the nurse's job description by implying that the nurse would perform tasks that are not permitted. It's important for the nurse to maintain professional boundaries and adhere to policies regarding their role.
D. This response is not appropriate because it focuses on the nurse's personal reasons and does not address the client's needs. It may come off as dismissive and fails to offer any alternative solutions or support.
