A nurse is providing teaching about the use of metered-dose inhalers to a client who has asthma. Which of the following instructions should the nurse include?
"Hold your breath for 10 seconds after each puff."
"Inhale rapidly for 1 to 2 seconds after depressing the canister."
“Hold the mouthpiece 4 Inches away from your open mouth.”
"Tilt your head forward while inhaling.”
The Correct Answer is A
A. "Hold your breath for 10 seconds after each puff.": This allows the medication to deposit deeply into the airways, enhancing absorption and therapeutic effect. It is a key step in proper MDI technique.
B. "Inhale rapidly for 1 to 2 seconds after depressing the canister.": Inhalation should be slow and deep over 3 to 5 seconds to allow proper delivery of the medication into the lungs.
C. “Hold the mouthpiece 4 inches away from your open mouth.”: The preferred technique is to place the mouthpiece directly in the mouth with lips sealed around it unless a spacer is used.
D. "Tilt your head forward while inhaling.": The correct method is to tilt the head slightly back to open the airway and facilitate deeper inhalation of the medication.

Explanation
A. "Make sure you are holding your baby when your son comes to visit you in the hospital.”: While involving the older sibling can help with bonding, holding the newborn continuously may cause feelings of jealousy or exclusion in the 4-year-old child.
B. “Surprise your son with a new bedroom after you bring the baby home.”: Sudden changes like moving a child’s bedroom without preparation can increase anxiety and feelings of insecurity during a time of significant family adjustment.
C. “Use medical terminology when teaching your son about your new baby.”: Using complex medical terms may confuse a preschooler; age-appropriate language and simple explanations are more effective for understanding and comfort.
D. "Purchase a gift to give to your son from your baby.”: Providing a gift from the new baby helps the older child feel included, valued, and less jealous, fostering positive feelings about the sibling relationship and easing the transition.

Explanation
- Prepare the client for cardiac catheterization: This client is experiencing an ST-elevation myocardial infarction (STEMI), a medical emergency requiring reperfusion therapy. Preparing for cardiac catheterization aligns with standard emergency management to restore coronary blood flow.
- Administer morphine 2 mg IV bolus for persistent cardiac pain: Morphine is used to relieve chest pain unresponsive to nitrates and reduce myocardial oxygen demand by lowering preload and afterload. The client still reports severe pain (7/10), justifying its use.
- Administer aspirin 81 mg PO chewable tablet: Aspirin is a first-line treatment in acute coronary syndromes to inhibit platelet aggregation and limit thrombus formation. A chewable form provides quicker absorption and is routine for suspected MI.
- Prepare to intubate the client: The client is alert, oriented, has normal respiratory rates, and maintains adequate oxygen saturation (96–98% on room air). There is no evidence of respiratory failure or airway compromise to justify intubation.
