A nurse is teaching a client who has a new prescription for cromolyn. Which of the following information should the nurse include in the teaching?
"Cromolyn will assist with dilating the bronchioles in your lungs."
"Cromolyn should take effect within 5 minutes."
"Cromolyn should be administered 1 hour after exercising."
"Cromolyn is used to prevent your condition from occurring."
The Correct Answer is D
A. "Cromolyn will assist with dilating the bronchioles in your lungs.": Cromolyn is not a bronchodilator and does not relax airway smooth muscles. Its primary action is to stabilize mast cells and prevent the release of inflammatory mediators.
B. "Cromolyn should take effect within 5 minutes.": Cromolyn works as a preventive medication and requires consistent use over time. It does not provide rapid relief of acute bronchospasm or asthma attacks.
C. "Cromolyn should be administered 1 hour after exercising.": For exercise-induced asthma, cromolyn should be administered 10–15 minutes before exercising, not after, to prevent symptoms. Timing is important for prophylactic effectiveness.
D. "Cromolyn is used to prevent your condition from occurring.": Cromolyn is a mast cell stabilizer used as a preventive therapy to reduce inflammation and prevent asthma attacks. It is most effective when taken regularly or before known triggers.

Correct Answer is C
Explanation
A. Protamine sulfate: Protamine sulfate is an antidote for heparin overdose, not for aspirin toxicity. It does not address salicylate-related symptoms such as tinnitus.
B. Diphenhydramine: Diphenhydramine is an antihistamine used for allergic reactions and motion sickness. It does not counteract aspirin toxicity or reduce salicylate levels.
C. Bicarbonate: Sodium bicarbonate is used in cases of aspirin (salicylate) toxicity to alkalinize the urine, which enhances the renal excretion of salicylates. This intervention helps reduce systemic toxicity, including symptoms like tinnitus.
D. Naloxone: Naloxone is an opioid antagonist used for opioid overdose. It has no effect on aspirin toxicity or salicylate-induced symptoms.
Correct Answer is {"dropdown-group-1":"E","dropdown-group-2":"A"}
Explanation
Rationale for Correct Choices:
- Heart rate: The client’s heart rate has increased from 58/min to 118/min, indicating possible thyrotoxicosis or over-replacement of levothyroxine. Tachycardia is a priority finding because it can lead to cardiovascular complications such as arrhythmias or chest pain.
- Pain: The client reports chest pain, which, combined with tachycardia and elevated blood pressure, may indicate cardiac strain or complications. Prompt assessment of pain helps identify potential cardiovascular compromise requiring urgent intervention.
Rationale for Incorrect Choices
- Weight: While notable changes in weight are important for monitoring thyroid treatment, they are not immediately life-threatening compared with tachycardia and chest pain.
- Skin: Skin changes provide supportive assessment information but are less immediately critical than cardiovascular status.
- Temperature: Elevated temperature indicates hypermetabolism or possible infection, but it is not as immediately life-threatening as the tachycardia and chest pain.
- Bowel sounds: Hyperactive bowel sounds reflect increased GI motility but are less urgent compared with cardiovascular and metabolic indicators.
