A nurse is reinforcing teaching with a client who has an electrolyte imbalance. Which of the following foods should the nurse include as the highest in potassium?

The correct answer is C. "Close your mouth around the mouthpiece." The rationale for this instruction is that it ensures that the medication reaches the lungs and does not escape through the mouth or nose. Albuterol is a bronchodilator that relaxes muscles in the airways and increases airflow to the lungs. It is used to treat or prevent bronchospasm, or narrowing of the airways, in people with asthma or certain types of chronic obstructive pulmonary disease (COPD). It is also used to prevent exercise-induced bronchospasm. Albuterol is delivered through a metered dose inhaler (MDI), which is a device that releases a measured amount of medication with each puff. To use an albuterol MDI correctly, the client should follow these steps :

• Shake the inhaler well before each spray.
• Remove the cap and look at the mouthpiece to make sure it is clean.
• Breathe out fully.
• Put the mouthpiece between your lips and close your mouth around it.
• Press down on the inhaler to release the medication as you start to breathe in slowly.
• Breathe in slowly and deeply over 3 to 5 seconds.
• Hold your breath for 10 seconds to allow the medication to reach your airways.
• Breathe out slowly.
• If you need another puff, wait 1 minute and repeat steps 4 to 8.

The correct answer is B. Diminished pulses on the affected extremity indicate impaired circulation, which can lead to tissue ischemia, necrosis, and compartment syndrome if not corrected promptly. This is a life-threatening complication that requires immediate intervention such as loosening or cutting off the cast, elevating the limb, or administering vasodilators. The other findings are not as urgent, although they may indicate other problems such as hematoma, infection, or nerve injury that need further assessment and treatment.
