A nurse is caring for a client with chest pain. Laboratory Results
1300:
Cardiac troponin T less than 0.5 ng/mL (less than 0.1 ng/mL). LDL 110 mg/dL (less than 130 mg/dL).
Total cholesterol 230 mg/dL (less than 200 mg/dL).
Complete the following sentence by using the list of options: After notifying the provider, the nurse should first:
check a STAT cardiac troponin.
request a prescription for a beta-blocker.
administer sublingual nitroglycerin
Notify the senior
The Correct Answer is C
Administer sublingual nitroglycerin.
Nitroglycerin is a vasodilator that can relieve chest pain caused by myocardial ischemia. The nurse should administer it as soon as possible to improve blood flow to the heart and reduce the risk of myocardial infarction. The nurse should also monitor the client’s blood pressure and heart rate after giving nitroglycerin, as it can cause hypotension and reflex tachycardia.
Choice A is wrong because checking a STAT cardiac troponin is not the first priority.
Cardiac troponin is a biomarker that indicates myocardial injury, but it may not rise until several hours after the onset of chest pain.
Therefore, it is not useful for immediate diagnosis or treatment of acute coronary syndrome. Choice B is wrong because requesting a prescription for a beta-blocker is not the first priority.
Beta-blockers are medications that can lower blood pressure and heart rate, and reduce the oxygen demand of the heart.
They can prevent or reduce the recurrence of chest pain and complications of acute coronary syndrome, but they are not indicated for immediate relief of chest pain.
Choice D is wrong because administering oxygen is not the first priority.
Oxygen therapy can increase the oxygen supply to the heart and reduce ischemia, but it is not necessary for all clients with chest pain.
Oxygen therapy should be based on the client’s oxygen saturation level and clinical condition.
If the client’s oxygen saturation is normal or high, oxygen therapy may not be beneficial and may even be harmful.

Correct Answer is A
Explanation
A client who is ambulatory and receiving oxygen should be evacuated first during a fire because they are at risk of fire and explosion from the oxygen source. The nurse should instruct the staff to turn off the oxygen supply, remove the oxygen device from the client, and assist them to walk out of the building using the nearest exit.
Choice B is wrong because a client who uses a wheelchair and is confused is not in immediate danger from the fire. They can be evacuated using a swing carry or an extremity carry by two staff members after the clients who are more vulnerable are evacuated.
Choice C is wrong because a client who is bedridden and wears a hearing aid is not in immediate danger from the fire. They can be evacuated using a cradle drop by one staff member after the clients who are more vulnerable are evacuated.
Choice D is wrong because a client who has a fracture and is in balance suspension traction is not in immediate danger from the fire. They can be evacuated using a special device such as a sked or a sled by two or more staff members after the clients who are more vulnerable are evacuated.
Correct Answer is C
Explanation
Dizziness is a manifestation of hypovolemia, which is a decrease in blood volume due to fluid loss. Hypovolemia can cause orthostatic hypotension, which is a drop in blood pressure when changing positions. This can lead to dizziness, lightheadedness, or fainting.
Choice A is wrong because it is not a sign of hypovolemia, but rather a possible cause of it. Epistaxis is a nosebleed that can result from trauma, infection, dryness, or coagulation disorders.
Choice B is wrong because it is not a specific sign of hypovolemia, but rather a nonspecific symptom that can have many causes. Headache can be associated with dehydration, but it can also be caused by stress, infection, inflammation, or other factors.
Choice D is wrong because it is not a sign of hypovolemia, but rather a sign of fluid volume excess.
Fluid volume excess is an increase in blood volume due to fluid retention or overload. Fluid volume excess can cause dyspnea, which is difficulty breathing or shortness of breath.
Normal ranges for blood pressure are 90/60 mm Hg to 120/80 mm Hg for adults. Normal ranges for heart rate are 60 to 100 beats per minute for adults.
