The nurse is planning care for a client with allergies who has an order for a sympathomimetic drug. The nurse is aware that the desired effect for this client is:
 
  1. relief of nasal dryness.
  2. relief of nasal stuffiness.
  3. calming of a wet cough.
  4. increased blood flow to the nose.

Question 2

The nurse is teaching a group of grade-school children about body functions. A student asks, Why do I sneeze? The nurse's best response is:
 
  1. A sneeze is caused by a contraction of your throat and lungs.
  2. The back part of your brain is in charge of sneezes and coughs.
  3. A sneeze is your body's way of getting rid of something irritating.
  4. You sneeze because your body needs to take a really deep breath.

Answer to Question 1

Correct Answer: 2
Rationale 1: Nasal dryness is not the goal of sympathomimetic drug use, although it can become a problem.
Rationale 2: Sympathomimetic drugs shrink the nasal mucous membranes and relieve stuffiness.
Rationale 3: Sympathomimetic drugs have a minimal effect on a wet cough.
Rationale 4: Arterioles shrink with less blood flow.
Global Rationale: Sympathomimetics (also called adrenergic agonists) with alpha-adrenergic activity are effective at relieving the nasal congestion associated with the common cold and allergic rhinitis when given by either the PO or intranasal route. Nasal dryness is not the goal of sympathomimetic drug use, although it can become a problem. Sympathomimetic drugs have a minimal effect on a wet cough. Arterioles shrink with less blood flow.

Answer to Question 2

Correct Answer: 3
Rationale 1: The diaphragm and other muscles of respiration contract.
Rationale 2: A sneeze is a reflex.
Rationale 3: Sneezing is triggered by irritants in the nasal passages. The diaphragm and other muscles of respiration contract.
Rationale 4: This is not the function of sneezing.
Global Rationale: The URT traps particulate matter and many pathogens, preventing them from being carried to the bronchioles and alveoli, where they would have access to the capillaries of the systemic circulation. A sneeze clears the nasal passages. The diaphragm and other muscles of respiration contract. A sneeze is a reflex that does not require a deep breath.
