A nurse in a provider's office is caring for a client who has asthma and reports that the manifestations get worse while exercising. Which of the following statements should the nurse make?

"Refrain from doing any exercises until your symptoms show improvement."

"Use your long-acting beta agonist inhaler after exercise-induced symptoms appear."

"Use your short-acting beta agonist inhaler before exercising."

"It is safe to exercise if your peak flow meter measures in the red zone."

Answer and Explanation

The Correct Answer is C

Rationale:

A. "Refrain from doing any exercises until your symptoms show improvement.": Completely avoiding exercise is not necessary for most people with asthma and can negatively impact cardiovascular health. The goal is to control symptoms so that safe activity is possible.

B. "Use your long-acting beta agonist inhaler after exercise-induced symptoms appear.": Long-acting beta agonists are used for maintenance therapy, not for quick relief. They are not appropriate for immediate symptom control before or after exercise.

C. "Use your short-acting beta agonist inhaler before exercising.": Short-acting beta agonists, such as albuterol, can be taken 5–20 minutes before exercise to prevent exercise-induced bronchospasm. This is the recommended approach for clients with exercise-triggered asthma.

D. "It is safe to exercise if your peak flow meter measures in the red zone.": The red zone indicates severe airway narrowing and poor asthma control, requiring immediate medical attention. Exercise in this state could worsen symptoms and lead to respiratory distress.

Correct Answer is ["2.5"]

Explanation

Calculation:

Desired dose = 20 mg.

Available concentration = 40 mg / 5 mL

= 8 mg/mL.

Calculate the volume to administer in milliliters (mL).

Volume to administer (mL) = Desired dose (mg) / Available concentration (mg/mL)

= 20 mg / 8 mg/mL

= 2.5 mL.

A. Atrial fibrillation B. Premature atrial complexes C. First-degree atrioventricular block D. Complete heart block

Correct Answer is C

Explanation

A. Atrial fibrillation: This dysrhythmia is characterized by an irregularly irregular rhythm with absent or unidentifiable P waves, not a prolonged constant P-R interval.

B. Premature atrial complexes: PACs involve early P waves that may have a normal or slightly different P-R interval, but they do not cause a consistently prolonged P-R interval across all beats.

C. First-degree atrioventricular block: A constant P-R interval greater than 0.20 seconds indicates a first-degree AV block. The atrial impulses are delayed at the AV node, but all impulses are conducted to the ventricles, producing a regular rhythm with prolonged P-R intervals.

D. Complete heart block: In complete heart block (third-degree AV block), there is no relationship between P waves and QRS complexes. The P-R interval is variable, unlike the constant prolongation seen in first-degree AV block.
