1. 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.

2. Which physiologic mechanism best describes the function of the sodium-potassium pump?

• A. active transport
• B. diffusion
• C. filtration
• D. osmosis

Correct answer: A

Rationale: Active transport is the correct answer as it accurately describes the process involved in the sodium-potassium pump. The pump utilizes energy to move ions against their concentration gradient, maintaining cellular concentrations. Diffusion (choice B) is a passive process where substances move from an area of higher concentration to lower concentration. Filtration (choice C) involves the movement of solutes based on pressure gradients. Osmosis (choice D) is the movement of water across a semipermeable membrane.

3. Jane Love, a 35-year-old gravida III para II at 23 weeks gestation, is seen in the Emergency Department with painless, bright red vaginal bleeding. Jane reports that she has been feeling tired and has noticed ankle swelling in the evening. Laboratory tests reveal a hemoglobin level of 11.5 g/dL. After evaluating the situation, the nurse determines that Jane is at risk for placenta previa, based on which of the following data?

• A. anemia
• B. edema
• C. painless vaginal bleeding
• D. fatigue

Correct answer: C

Rationale: Placenta previa is a disorder where the placenta implants in the lower uterine segment, causing painless bleeding in the third trimester of pregnancy. The bleeding results from tearing of the placental villi from the uterine wall as the lower uterine segment contracts and dilates. It can be slight or profuse and can include bright red, painless bleeding. While anemia (choice A) may be a consequence of chronic bleeding from placenta previa, it is not a direct indicator. Edema (choice B) and fatigue (choice D) are nonspecific symptoms that can occur in pregnancy but are not specific to placenta previa.

4. A patient 3 hours post-op from a hysterectomy is complaining of intense pain at the incision site. When assessing the patient, the nurse notes a BP of 169/93, pulse 145 bpm, and regular. What action should the nurse take?

• A. Reassure the patient that pain is normal following surgery.
• B. Administer prn Nifedipine and assess the client's response.
• C. Administer prn Meperidine HCL and assess the client's response.
• D. Recheck BP and pulse rate every 20 minutes for the next hour.

Correct answer: C

Rationale: The correct action for the nurse to take in this situation is to administer prn Meperidine HCL and assess the client's response. A BP of 169/93 and a pulse of 145 bpm indicate pain-related hypertension and sinus tachycardia, which are physiological responses to pain. Treating the cause of the increased pulse rate requires pain medication. Reassuring the patient about normal post-surgery pain is important, but addressing the physiological responses to pain is a priority. Administering Nifedipine, a calcium channel blocker, is not indicated for pain management but for hypertension. Rechecking the BP and pulse rate without addressing the pain directly does not address the underlying issue causing the elevated vital signs.

5. While Fluorouracil (5FU®) is being infused, a client complains of burning at the IV site. What should the nurse do first?

• A. Aspirate the IV site for blood return.
• B. Slow the infusion.
• C. Inspect the IV site.
• D. Stop the infusion.

Correct answer: C

Rationale: The correct first action for the nurse is to inspect the IV site. This is important to assess for any signs of infiltration or extravasation, which could be causing the burning sensation. Aspirating the IV site for blood return (Choice A) may not be the initial priority as it does not directly address the client's complaint of burning. Slowing the infusion (Choice B) may help alleviate discomfort but should not be done before inspecting the site. Stopping the infusion (Choice D) may be necessary, but inspecting the site should come first to determine the appropriate course of action.
