A nurse is caring for a client who has a cloudy, opaque area over the lens of one eye.
The nurse should identify that this is a manifestation of which of the following visual impairments?

Allowing time during the workday when each nurse can demonstrate proficiency is the best way to evaluate staff competency with the new equipment. This method ensures that the nurses can perform the skills correctly and safely under the charge nurse’s supervision and feedback.

Choice A is wrong because verbally questioning the staff about the new equipment does not assess their practical skills or ability to use the equipment correctly.

Choice B is wrong because requiring each nurse to take a written examination about the new equipment does not assess their hands-on skills or ability to troubleshoot problems with the equipment.

Choice D is wrong because asking each nurse to read the procedure and sign a form acknowledging competency does not verify that the nurses have understood the procedure or can apply it in practice.

It also relies on the nurses’ honesty and self-assessment, which may not be accurate or reliable.

Heat stroke is a serious condition caused by overheating of the body, usually as a result of prolonged exposure to or physical exertion in high temperatures. It can damage the brain and other internal organs, and can be fatal if not treated promptly.

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.
