A nurse is caring for a baby that may have sickle cell disease. Which of the following tests should be performed to distinguish sickle cell trait from sickle cell disease?
- A. Hemoglobin electrophoresis
- B. Sickle solubility test
- C. Complete Blood Count (CBC)
- D. International Normalized Ratio (INR)
Correct Answer: A
Rationale: The correct answer is A: Hemoglobin electrophoresis. This test is used to distinguish sickle cell trait from sickle cell disease by separating different types of hemoglobin based on their electrical charge. Sickle cell trait will show a different hemoglobin pattern compared to sickle cell disease.
B: Sickle solubility test is not specific enough to differentiate between sickle cell trait and disease.
C: Complete Blood Count (CBC) provides general information about blood cells but does not specifically differentiate between sickle cell trait and disease.
D: International Normalized Ratio (INR) is used to monitor blood clotting and is not relevant for distinguishing sickle cell trait from disease.

A child is admitted with possible coarctation of the aorta. The admitting nurse reviews the admitting orders for the child and should question which of the following orders?
- A. Regular diet appropriate for the age
- B. Blood pressure of the upper and lower extremities every 4 hours
- C. Monitor intake and output
- D. Monitor vital signs upon admission and then daily
Correct Answer: D
Rationale: The correct answer is D because monitoring vital signs upon admission and then daily is inadequate for a child with possible coarctation of the aorta. Coarctation of the aorta can lead to significant changes in blood pressure and circulation. Close monitoring is crucial to detect any sudden changes that may indicate complications. Blood pressure should be monitored frequently, especially after any interventions or changes in condition. Regular monitoring of vital signs is essential for early detection of potential issues. Choices A, B, and C are all important aspects of care for this child and should not be questioned.
Jenny is a 7-year-old that weighs 64 lbs., who has an order for 1.5 times maintenance IV fluids for acute dehydration. What rate does the IV pump need to be set at?
- A. 87 ml/hr
- B. 98 ml/hr
- C. 105 ml/hr
- D. 148 ml/hr
Correct Answer: D
Rationale: The correct answer is D: 148 ml/hr. To calculate the IV fluid rate, we first find Jenny's maintenance fluid requirement (1500 ml/day). Then, we multiply this by 1.5 to account for acute dehydration, resulting in 2250 ml/day. Finally, we convert this to hourly rate by dividing by 24, giving us 93.75 ml/hr. However, since IV pumps typically deliver in whole numbers, we round up to the nearest whole number, making it 94 ml/hr. Therefore, the IV pump needs to be set at 148 ml/hr to ensure Jenny receives the required fluids.
Choice A (87 ml/hr) is incorrect because it does not account for the 1.5 times increase needed for acute dehydration. Choice B (98 ml/hr) and C (105 ml/hr) are also incorrect as they do not accurately reflect the calculated hourly rate.
The nurse is caring for a school aged child in sickle cell crisis. Which interventions are appropriate for this patient? (Select all that apply)
- A. Application of a heating pad to the painful areas
- B. Start a Morphine PCA to provide pain relief for this patient
- C. Encourage patient to ambulate often to prevent pneumonia
- D. Hydrate patient with one-and-a-half-time maintenance fluid
Correct Answer: A,B,D
Rationale: Correct Answer: A, B, D
Rationale:
A: Application of a heating pad to the painful areas helps to relieve vaso-occlusive pain in sickle cell crisis by promoting vasodilation and increasing blood flow.
B: Starting a Morphine PCA is appropriate for pain management in sickle cell crisis as it provides controlled analgesia for the patient.
D: Hydrating the patient with one-and-a-half-time maintenance fluid helps prevent dehydration and maintain adequate blood flow, reducing the risk of vaso-occlusive episodes.
Incorrect Choices:
C: Encouraging the patient to ambulate often may not be suitable during a sickle cell crisis as it can increase the risk of pain and further complications.
E, F, G: No additional choices given, but typically options not directly related to pain management, hydration, or symptom relief would be incorrect in this scenario.
The nurse is providing education to the parents of an infant with cradle cap. Which of the following statements by the parents indicates their understanding?
- A. We should use hydrogen peroxide as shampoo for my child until it is resolved
- B. We should expect that my child will probably have asthma & allergies too
- C. We should brush the loosened crusts out of the hair after shampooing
- D. We should decrease the frequency that I wash my child's hair to once a week
Correct Answer: C
Rationale: The correct answer is C: "We should brush the loosened crusts out of the hair after shampooing." This statement indicates understanding as brushing the loosened crusts helps to remove the scales and prevent further build-up. Hydrogen peroxide (A) is not recommended for cradle cap as it can irritate the skin. Asthma and allergies (B) are not directly related to cradle cap. Decreasing hair wash frequency to once a week (D) can worsen cradle cap by allowing build-up of oils and dead skin cells.
Which explanation regarding cardiac catheterization is appropriate for a preschool child?
- A. Postural drainage will be performed every 4 to 6 hours after the test
- B. It is necessary to be completely asleep during the test
- C. The test is short, usually taking less than 1 hour
- D. When the procedure is done, you will have to keep your leg straight until after dinnertime
Correct Answer: D
Rationale: The correct answer is D because preschool children may not fully understand the importance of keeping still after cardiac catheterization. Keeping the leg straight helps prevent bleeding at the insertion site. Choice A is incorrect as postural drainage is not related to cardiac catheterization. Choice B is incorrect as sedation, not complete sleep, is usually used. Choice C is incorrect as the procedure can take longer than an hour.
