A nurse is caring for a client who has AIDS.
Which of the following solutions should the nurse use to disinfect the client's overbed table following a blood spill?
Hydrogen peroxide.
Bleach.
Isopropyl alcohol.
Chlorhexidine.
The Correct Answer is B
Choice A rationale:
Hydrogen peroxide. Hydrogen peroxide is not the recommended solution for disinfecting surfaces following a blood spill. While it can be used to clean wounds and may have some disinfectant properties, it is not as effective as bleach in destroying bloodborne pathogens.
Choice B rationale:
Bleach. Bleach is the appropriate choice for disinfecting surfaces contaminated with blood. A 10% bleach solution (1 part bleach to 9 parts water) is effective at killing bloodborne pathogens such as HIV and hepatitis B and C viruses. It should be used in healthcare settings to ensure proper disinfection after a blood spill.
Choice C rationale:
Isopropyl alcohol. Isopropyl alcohol is an effective disinfectant for some purposes, but it may not be as effective as bleach against bloodborne pathogens. It is commonly used for cleaning and disinfecting skin before medical procedures but is not the recommended choice for disinfecting surfaces following a blood spill.
Choice D rationale:
Chlorhexidine. Chlorhexidine is an antiseptic solution often used for skin disinfection before surgical procedures or invasive medical interventions. It is not typically used for disinfecting surfaces contaminated with blood.

Correct Answer is C
Explanation
Choice A rationale:
Epinephrine is not typically used to treat nausea. Nausea is usually managed with antiemetic medications.
Choice B rationale:
Epinephrine is not used to treat hand tremors. Hand tremors may be related to various conditions, and their management would depend on the underlying cause.
Choice C rationale:
The correct manifestation that epinephrine can help treat is "Swelling of the lips." Epinephrine is commonly used to treat severe allergic reactions (anaphylaxis), which can cause swelling of the lips, tongue, and throat. Epinephrine helps to reverse these symptoms by constricting blood vessels and opening the airways.
Choice D rationale:
Epinephrine is not used to treat hyperglycemia. Hyperglycemia is managed with insulin or other antidiabetic medications, not epinephrine.
Correct Answer is B
Explanation
The correct answer is Choice B: Administer the medication to the toddler each evening.
Choice B rationale: Montelukast is a leukotriene receptor antagonist used for the long-term management of asthma, especially in preventing nighttime symptoms. It is typically prescribed to be administered once daily in the evening to provide optimal therapeutic benefits. By instructing the parents to give the medication each evening, the nurse promotes adherence to the prescribed dosing schedule and helps maximize the medication's effectiveness in controlling the toddler's asthma symptoms.
Choice A rationale: While some medications can be mixed with juice or other liquids to make them more palatable for children, montelukast should not be dissolved in a drink. Instead, it can be mixed with a spoonful of cold, soft food, such as applesauce or ice cream, if necessary, to facilitate administration. Mixing with juice could potentially alter the medication's efficacy or create an unpleasant taste.
Choice C rationale: Montelukast is not indicated for use as a quick-relief medication prior to physical activity. It is a maintenance medication intended for long-term asthma control rather than immediate relief of acute symptoms. Providing an additional dose of montelukast before physical activity would not serve the intended purpose and could increase the risk of side effects.
Choice D rationale: Montelukast is not meant to be used as a rescue medication for acute asthma attacks. It is a long-term control medication that helps prevent asthma attacks and improve overall symptom management. For acute asthma attacks, the toddler would require a fast-acting beta-agonist or other appropriate rescue medication prescribed by their healthcare provider. Administering montelukast during an acute asthma attack would not provide the rapid relief needed to alleviate symptoms and could potentially delay appropriate treatment.
