The test used to differentiate sickle cell trait from sickle cell disease is:
- A. Sickle cell preparation.
- B. Peripheral smear.
- C. Sickledex.
- D. Hemoglobin electrophoresis
Correct Answer: D
Rationale: The correct test to differentiate between sickle cell trait and sickle cell disease is hemoglobin electrophoresis. This test separates different types of hemoglobin based on their electrical charge, allowing for the identification of specific hemoglobin variants like HbS in sickle cell disease. Sickle cell preparation and Sickledex are not specific tests for this differentiation. While a peripheral smear can show sickle cells, it does not provide a definitive differentiation between the trait and the disease as it doesn't identify the specific hemoglobin variant present.

During a screening on a patient with a recent cast on the left lower extremity, which of the following statements should the nurse be most concerned about?
- A. The patient reports, "I didn't keep my extremity elevated as the doctor asked me to."?
- B. The patient reports, "I have been having pain in my left calf."?
- C. The patient reports, "My left leg has really been itching."?
- D. The patient reports, "The arthritis in my wrists is flaring up when I put weight on my crutches."?
Correct Answer: B
Rationale: The correct answer is B because pain in the left calf could indicate a potential neurovascular complication related to the casted extremity. It could suggest issues such as compartment syndrome or impaired circulation. Option A is not as concerning since not elevating the extremity may lead to swelling but is not an immediate concern. Option C indicates itching, which is common with casts and not as concerning as potential neurovascular issues. Option D, regarding arthritis in the wrists, is unrelated to the lower extremity issue being screened for.
A 55-year-old female asks a nurse the following, “Which mineral/vitamin is the most important to prevent the progression of osteoporosis?†The nurse should state:
- A. Potassium
- B. Magnesium
- C. Calcium
- D. Vitamin B12
Correct Answer: C
Rationale: The correct answer is C: Calcium. Calcium is essential for maintaining bone health and is crucial in preventing osteoporosis. Adequate calcium intake, along with vitamin D, is vital for bone strength. While other minerals and vitamins are also important for overall health, in the context of preventing osteoporosis, calcium plays a primary role. Potassium (Choice A), Magnesium (Choice B), and Vitamin B12 (Choice D) are important for various bodily functions but are not as directly linked to preventing osteoporosis as calcium.
A 32-year-old male with a complaint of dizziness has an order for Morphine via IV. What should the nurse do first?
- A. Check the patient's chest x-ray results.
- B. Retake vitals including blood pressure.
- C. Perform a neurological screening on the patient.
- D. Request the physician on-call to assess the patient.
Correct Answer: B
Rationale: The correct first action for the nurse to take in this situation is to retake the patient's vitals, including blood pressure. Dizziness can be a sign of hypotension, which may be a contraindication for administering Morphine. Checking the chest x-ray results (Choice A) would not be the priority in this case as addressing the dizziness is more urgent. Performing a neurological screening (Choice C) may be important but not the first step when a patient presents with dizziness and an order for Morphine. Requesting the physician to assess the patient (Choice D) should come after the initial assessment and vitals retake.
Melissa Smith came to the Emergency Department in the last week before her estimated date of confinement complaining of headaches, blurred vision, and vomiting. Suspecting PIH, the nurse should best respond to Melissa's complaints with which of the following statements?
- A. "The physician will probably want to admit you for observation."?
- B. "The physician will probably order bedrest at home."?
- C. "These are really dangerous signs."?
- D. "The physician will probably prescribe some medicine for you."?
Correct Answer: B
Rationale: Pregnancy-induced hypertension (PIH) is a hypertensive disorder of pregnancy that can present after 20 weeks gestation. It is characterized by symptoms like edema, hypertension, and proteinuria, which can progress to conditions like pre-eclampsia and eclampsia. The best approach for a client with advanced PIH is rest, and home provides the most suitable environment for it. Hospitalization is not typically necessary for PIH unless there are severe complications. Medication alone is not the primary intervention for PIH; management often involves monitoring, rest, and close medical supervision. Therefore, advising bedrest at home is the most appropriate response to help manage PIH symptoms and prevent further complications, such as pre-eclampsia or eclampsia. The other options, like hospitalization for observation, emphasizing the danger of the signs without providing guidance, or assuming medication as the primary solution, are not in line with the standard management approach for PIH.
A nurse is returning phone calls in a pediatric clinic. Which of the following reports most requires the nurse's immediate attention and phone call?
- A. An 8-year-old boy has been vomiting, appears to have slower movements, and has a history of an atrioventricular shunt placement.
- B. A 10-year-old girl feels a dull pain in her abdomen after doing sit-ups in gym class.
- C. A 7-year-old boy has been having a low fever and headache for the past 3 days and has a history of an anterior knee wound.
- D. A 7-year-old girl who had a cast on her right ankle is complaining of itching.
Correct Answer: A
Rationale: The correct answer is the 8-year-old boy with vomiting, slower movements, and a history of an atrioventricular shunt placement. This report requires immediate attention because the symptoms could indicate a blocked shunt, which is a serious medical condition needing urgent evaluation and intervention. Slower movements in the context of an atrioventricular shunt history could suggest increased intracranial pressure. The other choices involve less urgent issues: choice B describes post-exercise pain, choice C presents with a low-grade fever and headache that could be due to a mild infection, and choice D reports itching associated with a cast, which is a common issue and less critical compared to a potentially blocked shunt.
