A charge nurse is discussing evidence-based practice (EBP) with a newly licensed nurse.
Which of the following information should the nurse include when discussing the hierarchy of evidence?
One of the highest levels of evidence are randomized, controlled, double-blind studies.
Ideas, editorials, and opinions are highly valued in determining EBP.
The purpose of the hierarchy of evidence is to help the nurse compare patient values with research findings.
All forms of evidence should be considered equally when.
The Correct Answer is A
One of the highest levels of evidence are randomized, controlled, double-blind studies. This is because these studies reduce the risk of bias and confounding factors by randomly assigning participants to intervention or control groups, blinding the participants and researchers to the group allocation, and using a placebo or standard treatment as a comparison.
Choice B is wrong because ideas, editorials, and opinions are considered low levels of evidence as they are based on personal views and not on rigorous research methods.
Choice C is wrong because the purpose of the hierarchy of evidence is to help the nurse evaluate the quality and strength of the research findings, not to compare patient values with research findings.
Patient values are important for evidence-based practice, but they are not part of the hierarchy of evidence.
Choice D is wrong because all forms of evidence should not be considered equally when determining evidence-based practice. The hierarchy of evidence ranks different types of research designs according to their validity and applicability, and the nurse should use the highest level of evidence available for their clinical question.

Correct Answer is A
Explanation
Some of the symptoms of heat stroke are:
• High body temperature of 104 F (40 C) or higher
• Altered mental state or behavior, such as confusion, agitation, slurred speech, seizures or coma
• Lack of sweating despite the heat
• Red, hot and dry skin
• Rapid and strong pulse
• Throbbing headach
• Nausea and vomiting
Choice B is wrong because it is necessary to call 911 if someone has heat stroke. Heat stroke is a medical emergency that requires immediate attention and cooling of the body.
Choice C is wrong because it is not normal to vomit and not sweat during a marathon. Vomiting and lack of sweating are signs of dehydration and heat stroke, which indicate that the body is unable to regulate its temperature properly.
Choice D is wrong because getting the patient to a cooler, air-conditioned place will not reverse the heat exhaustion.
Heat exhaustion is a milder form of heat-related illness that can lead to heat stroke if not treated. Heat exhaustion symptoms include heavy sweating, weakness, dizziness, nausea and muscle cramps. Getting the patient to a cooler place may help with heat exhaustion, but heat stroke requires more aggressive cooling measures such as immersing the patient in cold water or applying ice packs to the body.
Correct Answer is A
Explanation
This is because hypokalemia (low potassium level in the blood) can cause abnormal heart rhythms (arrhythmia) that can be life-threatening and require urgent medical attention. A cardiac monitor can help detect and treat any arrhythmia that may occur.
Choice B is wrong because administering a laxative can worsen hypokalemia by causing more potassium loss through the digestive tract. Laxative use is one of the possible causes of hypokalemia.
Choice C is wrong because placing the client on seizure precautions is not a priority intervention for hypokalemia. Seizures are not a common symptom of hypokalemia, although muscle weakness and cramps may occur.
Choice D is wrong because restricting high potassium foods is not a priority intervention for hypokalemia. In fact, increasing potassium intake through foods or supplements may be helpful in less serious cases of hypokalemia. However, this should be done according to the doctor’s recommendation and with careful monitoring of blood potassium levels.
Normal blood potassium levels for an adult range from 3.6 to 5.2 millimoles per liter (mmol/L). A very low potassium level (less than 2.5 mmol/L) can be life threatening.
