Question 1 of 5
Albuterol can be given in all but which of these forms:
Correct Answer: A
Rationale: Albuterol is typically administered through inhalation as an aerosol or nebulized solution to provide quick relief of bronchospasm in conditions such as asthma or chronic obstructive pulmonary disease. It can also be administered intravenously in emergency situations for severe bronchospasm or anaphylaxis. Albuterol is not formulated as an extended-release oral medication due to the need for rapid onset of action in managing acute bronchospasm.
Question 2 of 5
The nurse is obtaining a medication history on a patient presenting with chest pain. What drug classification would necessitate the nurse informing the provider before beginning the prescribed nitroglycerin?
Correct Answer: B
Rationale: Phosphodiesterase inhibitors (Erectile Dysfunction medications) are contraindicated with nitroglycerin due to the potential for severe hypotension and cardiovascular collapse when taken together. It is essential for the nurse to inform the provider before administering nitroglycerin if the patient is taking phosphodiesterase inhibitors to prevent any harmful interactions.
Question 3 of 5
_____________ is the period of time required for concentration of a drug to be reduced by 50%.
Correct Answer: C
Rationale: Half-life is the period of time required for the concentration of a drug in the body to be reduced by 50%. It is an important pharmacokinetic parameter that helps determine dosing intervals and drug accumulation or clearance. Understanding a drug's half-life is crucial in optimizing dosing regimens and achieving desired therapeutic outcomes. Efficacy refers to the maximum therapeutic effect that a drug can produce. Steady-state concentration is the consistent level of drug concentration achieved after repeated doses. Clearance is the rate at which a drug is removed from the body.
Question 4 of 5
Glyceryl trinitrate for angina is most effective when given:
Correct Answer: C
Rationale: Glyceryl trinitrate, also known as nitroglycerin, is a medication commonly used for the management of angina (chest pain). When administered sublingually (under the tongue), glyceryl trinitrate is rapidly absorbed through the highly vascular sublingual mucosa, leading to a quick onset of action. The sublingual route allows for the drug to enter the bloodstream directly without being metabolized by the liver first, resulting in faster relief of angina symptoms. This makes sublingual administration the most effective route for managing acute episodes of angina. Other routes of administration, such as oral, subcutaneous, intravenous, or intramuscular, would not provide the same rapid and reliable relief for angina.
Question 5 of 5
The number of people with hypertension in the United States is estimated to be
Correct Answer: B
Rationale: The estimated number of people with hypertension in the United States is around 25 million. Hypertension, commonly known as high blood pressure, is a prevalent health condition affecting a significant portion of the population. This estimate is based on data collected from various healthcare sources and studies on the prevalence of hypertension in the country. It is important to monitor and manage hypertension effectively to prevent the associated health risks, such as heart disease and stroke.
