Question 1 of 4
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 2 of 4
During a stress test, a patient complains of severe chest pain. Which of the following medications is the most appropriate to relieve this discomfort?
Correct Answer: C
Rationale: In this scenario, the most appropriate medication to relieve severe ischemic chest pain during a stress test is Procardia. Procardia, a calcium channel blocker, is effective in quickly alleviating chest pain by dilating coronary arteries, improving blood flow to the heart muscle. Aspirin, although important for antiplatelet effects, is not the best choice for immediate relief of severe chest pain. Diazoxide is a vasodilator used in hypertensive emergencies, not for acute chest pain. Mannitol is an osmotic diuretic used to reduce intracranial pressure, not for chest pain relief.
Question 3 of 4
A nurse gave medications to the wrong client. She stated the client responded to the name called. What is the nurse's appropriate documentation?
Correct Answer: D
Rationale: In the case where medications are given to the wrong client, the appropriate documentation by the nurse should involve completely filling out an incident report. This report is essential for tracking errors, implementing corrective measures, and ensuring patient safety. Choice A is incorrect because solely noting the drug given does not address the severity of the error. Choice B is incorrect because even if the client was not hurt, documentation is crucial for quality improvement and risk prevention. Choice C is incorrect as noting the client's orientation does not adequately address the medication error and its implications.
Question 4 of 4
In a client with asthma who develops respiratory acidosis, what should the nurse expect the client's serum potassium level to be?
Correct Answer: B
Rationale: In respiratory acidosis, the serum potassium level is expected to be elevated. This occurs because potassium shifts from cells into the bloodstream as a compensatory mechanism to maintain acid-base balance. Choices A, C, and D are incorrect. A normal potassium level is not expected in respiratory acidosis. A low potassium level is more commonly associated with alkalosis, not acidosis. The potassium level is indeed related to pH changes in respiratory acidosis, leading to the expected elevation.
