Question 1 of 5
Which physiologic mechanism best describes the function of the sodium-potassium pump?
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.
Question 2 of 5
A patient has experienced a severe third-degree burn to the trunk in the last 36 hours. Which phase of burn management is the patient in?
Correct Answer: A
Rationale: The correct answer is A: Shock phase. The shock phase occurs within the first 24-48 hours of burn management. During this phase, the focus is on stabilization, fluid resuscitation, and monitoring for potential complications.
Choice B, the Emergent phase, is incorrect as it refers to the initial phase of burn care immediately after the injury.
Choice C, the Healing phase, occurs later in the treatment process when the wound starts to repair itself.
Choice D, the Wound proliferation phase, is not a recognized phase in burn management.
Question 3 of 5
The test used to differentiate sickle cell trait from sickle cell disease is:
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.
Question 4 of 5
A patient's nurse taking a history notes complaints of SOB and weakness in the lower extremities. The patient has a history of hyperlipidemia and hypertension. Which of the following may be occurring?
Correct Answer: B
Rationale: In this scenario, the patient's symptoms of shortness of breath (SO
B) and weakness in the lower extremities, along with a history of hyperlipidemia and hypertension, are suggestive of a myocardial infarction (MI). It is important to note that MI can present with a variety of symptoms, including those affecting the respiratory system and muscle weakness.
Choices A, C, and D are incorrect because the patient's symptoms are more indicative of a myocardial infarction rather than congestive heart failure (CHF), chronic obstructive pulmonary disease (COP
D), or peripheral vascular disease (PV
D).
Question 5 of 5
A 32-year-old male with a complaint of dizziness has an order for Morphine via IV. What should the nurse do first?
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.
