The nurse is reviewing a patient's arterial blood gas results. Which condition should the nurse suspect is developing in this patient?
 
  1. chronic obstructive pulmonary disease, hypercapnia
  2. alkalytic response from sympathomimetics
  3. hypercapnia with respiratory acidosis
  4. hypoxemic respiratory failure, metabolic acidosis

Question 2

A patient who has been feeling more anxious since the recent and unexpected death of his wife is experiencing an acute asthma attack. Rank the following events in the most likely order of occurrence.
 
  Choice 1. The patient states, I feel like my throat is closing off and I can't breathe very well.
  Choice 2. The patient is allergic to aspirin but unknowingly ingested a product with aspirin among its ingredients.
  Choice 3. The patient's respiratory rate is 32 breaths per minute and his oxygen saturation level falls from 94 to 89.
  Choice 4. Inflammatory mediators are released and inflammatory cells are activated.
  Choice 5. The patient is taken to the hospital via an ambulance and treated with medication.

Answer to Question 1

Correct Answer: 4
Arterial blood gases are used to evaluate alveolar ventilation and gas exchange. With hypoxemic respiratory failure, the PaCO2 may be normal, 35 to 45 mmHg, or even low due to tachypnea. A pH of less than 7.35 and low bicarbonate levels indicate metabolic acidosis, typical of hypoxemic respiratory failure. Hypercapnia from COPD would be respiratory acidosis. Sympathomimetics do not produce alkalosis. The values do not indicate respiratory acidosis from hypercapnia, as the PaCO2 is within normal limits.

Answer to Question 2

Correct Answer: 2, 4, 1, 3, 5
Aspirin-containing products are a common pharmacologic trigger for acute asthma attacks. When a trigger is present, an acute or early response develops in the hyperreactive airways predisposed to bronchospasm. Sensitized mast cells in the bronchial mucosa release inflammatory mediators such as histamine, prostaglandins, and leukotrienes. These events lead to bronchoconstriction, airway edema, and impaired mucociliary clearance. Airway narrowing limits airflow and increases the work of breathing; trapped air mixes with inhaled air, impairing gas exchange. Hospitalization may be required to prevent the complications of an asthma attack, which include acute respiratory failure, dehydration, respiratory infection, atelectasis, pneumothorax, and cor pulmonale.

Did you know?

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.

Pope Sylvester II tried to introduce Arabic numbers into Europe between the years 999 and 1003, but their use did not catch on for a few more centuries, and Roman numerals continued to be the primary number system.

Did you know?

Astigmatism is the most common vision problem. It may accompany nearsightedness or farsightedness. It is usually caused by an irregularly shaped cornea, but sometimes it is the result of an irregularly shaped lens. Either type can be corrected by eyeglasses, contact lenses, or refractive surgery.

Did you know?

Prostaglandins were first isolated from human semen in Sweden in the 1930s. They were so named because the researcher thought that they came from the prostate gland. In fact, prostaglandins exist and are synthesized in almost every cell of the body.
