A nurse is caring for a client who is found unresponsive and pulseless in their room. An ECG confirms the client is in pulseless ventricular tachycardia (VT). The nurse should anticipate the need for taking which of the following actions?

Choice A reason: Smoking is a significant trigger for asthma attacks. Tobacco smoke contains numerous irritants and chemicals that can inflame the airways and make asthma symptoms worse. Avoiding smoking, as well as second-hand smoke, is crucial for managing asthma and reducing the likelihood of attacks.

Choice B reason: The peak flow meter is a crucial tool for asthma management. It measures how well air moves out of the lungs. If a reading is in the red zone, it means that the airway is significantly obstructed, and immediate medical intervention is required. Calling 911 ensures that the patient gets timely help, which can be life-saving in severe asthma attacks.

Choice C reason: Washing bed clothes regularly is important because dust mites, which are common asthma triggers, thrive in bedding. Regular washing at a high temperature can kill these mites and reduce their presence, thereby minimizing one of the common indoor asthma triggers.

Choice D reason: Keeping the house fresh with air fresheners is actually not recommended for asthma patients. Many air fresheners contain volatile organic compounds (VOCs) and other chemicals that can irritate the airways and trigger asthma symptoms. Instead, maintaining good ventilation and using non-chemical methods to keep the air fresh is preferred.

Choice E reason: Using an inhaler two hours before exercising is not a standard recommendation for asthma management. Typically, a quick-relief inhaler (bronchodilator) is used 15-30 minutes before exercise to prevent exercise-induced bronchoconstriction. The two-hour mark is not effective in ensuring the medication's peak action during the exercise period.

Choice A reason: Pyridostigmine is used to treat myasthenia gravis, not for preventing Addisonian crisis in patients undergoing adrenalectomy. It is not related to adrenal hormone replacement.

Choice B reason: Tensilon (edrophonium) is used in the diagnosis of myasthenia gravis and is not relevant for managing adrenal insufficiency or preventing Addisonian crisis.

Choice C reason: Hydrocortisone intravenously is the correct choice for preventing Addisonian crisis in a client scheduled for adrenalectomy. Hydrocortisone provides the necessary corticosteroid replacement to manage the deficiency of adrenal hormones during and after surgery.

Choice D reason: Spironolactone is a potassium-sparing diuretic used to treat conditions like heart failure and hypertension. It is not used for preventing Addisonian crisis or managing adrenal insufficiency.
