Question

1. you arrive at a local park where you find a 20 - year - old female. the patient says she was rolling near the garden and started feeling sick. she is complaining of cough, shortness of breath, tight chest, and audible wheezing. she is most likely suffering from (an):

a. pneumonia
b. heart failure
c. copd
d. asthma

1. you should expect this patient to be carrying what type of medication?

a. aspirin
b. nitroglycerin
c. inhaler - albuterol
d. antibiotics

1. name the three layers of the heart and their functions:

1.
2.
3.

1. name the three (3) main electrolytes in the heart:

1.
2.
3.

1. what electrolyte is most important to cardiac function?
2. too little or too much of this electrolyte: can lead to cardiac arrest.
3. what is the normal temperature of the human body?
4. a fever is a good indicator a person has a(n)
5. normal oxygen saturation percentage is in your blood % to %
6. saturation levels less than % may require you to provide oxygen to your patient.
7. normal range of potassium level is:

Explanation:

• Question 90: The patient's symptoms of cough, shortness of breath, tight chest, and wheezing are characteristic of asthma, especially in a young person with no other long - term conditions indicated. Pneumonia usually has additional symptoms like fever and productive cough, heart failure typically presents with more systemic symptoms related to fluid overload, and COPD is more common in older individuals with a long - term smoking history.
• Question 91: Albuterol is a common bronchodilator used in inhalers for asthma patients to relieve bronchospasm. Aspirin is an analgesic and anti - inflammatory, nitroglycerin is for angina relief, and antibiotics are for treating infections.
• Question 92: The three layers of the heart are the epicardium (protective outer layer), myocardium (muscular middle layer responsible for contraction), and endocardium (inner lining that lines the chambers and valves).
• Question 93: The three main electrolytes in the heart are sodium (important for depolarization), potassium (vital for repolarization), and calcium (involved in muscle contraction).
• Question 94: Potassium is crucial for maintaining the normal electrical rhythm of the heart as it is involved in the repolarization phase of the cardiac action potential.
• Question 95: Potassium. Imbalances in potassium levels can lead to life - threatening arrhythmias and cardiac arrest.
• Question 96: The normal temperature of the human body is 37°C (98.6°F).
• Question 97: A fever is a good indicator a person has an infection. The body's immune response raises the body temperature to fight off pathogens.
• Question 98: Normal oxygen saturation percentage in the blood is 95% to 100%.
• Question 99: Saturation levels less than 90% may require oxygen administration to the patient.
• Question 100: The normal range of potassium level is 3.5 - 5.0 mEq/L.

Answer:

• 90. D. Asthma
• 91. C. Inhaler - Albuterol
• 92. 1. Epicardium: Protective outer layer; 2. Myocardium: Muscular layer for contraction; 3. Endocardium: Inner lining of chambers and valves
• 93. 1. Sodium; 2. Potassium; 3. Calcium
• 94. Potassium
• 95. Potassium
• 96. 37°C (98.6°F)
• 97. Infection
• 98. 95; 100
• 99. 90
• 100. 3.5 - 5.0 mEq/L
