A nurse is providing care for an adolescent who was brought to the emergency department (ED) by their guardians due to pain in the left arm that started the previous evening.
The adolescent has a history of sickle cell disease diagnosed at age 4. They have a prescription for oral morphine sulfate and took one dose the previous evening at 1800 and another this morning at 0900.
The adolescent reports no relief from pain, rating it as 9 on a scale of 0 to 10. For each potential provider’s prescription, specify if the prescription is anticipated, nonessential, or contraindicated for the client.
Intravenous fluids (IVF) at maintenance rate
Meperidine IV for pain
Ice packs to the affected area for 15 min on/15 min off
Oxygen 2 L/min via nasal cannula
The Correct Answer is {"A":{"answers":"A"},"B":{"answers":"C"},"C":{"answers":"B"},"D":{"answers":"A"}}
Choice A rationale
Intravenous fluids (IVF) at maintenance rate is anticipated for the client. Dehydration can increase the viscosity of the blood and promote sickling in clients with sickle cell disease. Therefore, maintaining hydration is crucial in managing sickle cell crises.
Choice B rationale
Meperidine IV for pain is contraindicated for the client. Meperidine has been associated with a higher risk of seizures, especially in clients with kidney dysfunction, which can occur in sickle cell disease due to sickling in the renal vasculature.
Choice C rationale
Ice packs to the affected area for 15 min on/15 min off is nonessential for the client. While cold therapy can help reduce inflammation and numb pain, it can also lead to vasoconstriction, which can potentially exacerbate sickling. Therefore, it’s generally recommended to use warm compresses rather than ice packs in clients with sickle cell disease.
Choice D rationale
Oxygen 2 L/min via nasal cannula is anticipated for the client. Hypoxia can trigger sickling in clients with sickle cell disease, so oxygen therapy is often used to increase oxygen saturation and reduce the risk of sickling.

Correct Answer is {"A":{"answers":"A"},"B":{"answers":"A"},"C":{"answers":"B"},"D":{"answers":"A"}}
Explanation
- WBC count: This finding is not consistent with either sickle cell anemia or hemophilia. Both conditions do not typically cause an increase in white blood cell count.
- Temperature: This finding is not consistent with either sickle cell anemia or hemophilia. Neither condition is associated with an elevated body temperature unless there is a concurrent infection.
- Bleeding: This finding is consistent with hemophilia. Hemophilia is a bleeding disorder where the blood does not clot properly. This can lead to spontaneous bleeding as well as bleeding following injuries or surgery.
- Reported pain: This finding is consistent with sickle cell anemia. Sickle cell anemia can cause episodes of pain when sickle-shaped red blood cells block blood flow through tiny blood vessels to your chest, abdomen and joints. Pain can also occur in your bones.
Correct Answer is C
Explanation
Choice C rationale
The apex of the heart is the most appropriate site to assess an infant’s heart rate. In infants, the apical pulse provides the most accurate assessment of heart rate. The apical pulse is located at the fifth intercostal space at the midclavicular line.
Choice A rationale
The carotid artery is not typically used to assess an infant’s heart rate. This site is more commonly used in adults and older children.
Choice B rationale
The brachial artery can be used to assess an infant’s heart rate, but it is typically used for blood pressure measurements rather than heart rate assessments.
Choice D rationale
The radial artery is not typically used to assess an infant’s heart rate. This site is more commonly used in adults and older children.
