An adult patient is admitted for an asthma attack. Which assessment obtained by the nurse would support that beta2 adrenergic agonist albuterol was effective?
Decrease in wheezing present on auscultation
Respiratory rate increased to 38 breaths/min
Sputum production is clear and watery
Use of neck muscles
The Correct Answer is A
Choice A reason: Decrease in wheezing present on auscultation indicates that albuterol was effective. Albuterol is a bronchodilator that relaxes the smooth muscles of the airways and reduces the airway resistance. This improves the airflow and reduces the wheezing sound that is caused by the turbulent flow of air through the narrowed airways.
Choice B reason: Respiratory rate increased to 38 breaths/min does not indicate that albuterol was effective. It indicates that the patient is still experiencing respiratory distress and hypoxia. The normal respiratory rate for adults is 12 to 20 breaths/min. A high respiratory rate can also be a side effect of albuterol, as it can stimulate the sympathetic nervous system and increase the heart rate and blood pressure.
Choice C reason: Sputum production is clear and watery does not indicate that albuterol was effective. It indicates that the patient has a productive cough and is expelling mucus from the lungs. Sputum production is not directly affected by albuterol, as it does not have anti-inflammatory or mucolytic properties.
Choice D reason: Use of neck muscles does not indicate that albuterol was effective. It indicates that the patient is using accessory muscles to breathe and is exerting more effort to inhale. This is a sign of severe respiratory distress and airway obstruction. Albuterol should relieve the bronchospasm and reduce the need for accessory muscle use.

Correct Answer is ["B","C"]
Explanation
Choice A reason: Oliguria is not a forward effect of left ventricular heart failure. It is a backward effect that occurs due to reduced renal perfusion and activation of the renin-angiotensin-aldosterone system.
Choice B reason: Increased heart rate is a forward effect of left ventricular heart failure. It is a compensatory mechanism that occurs due to reduced cardiac output and sympathetic stimulation.
Choice C reason: Wet cough is a forward effect of left ventricular heart failure. It is a sign of pulmonary congestion and edema that result from increased pressure in the pulmonary veins and capillaries.
Choice D reason: Confusion is not a forward effect of left ventricular heart failure. It is a backward effect that occurs due to reduced cerebral perfusion and hypoxia.
Choice E reason: Jugular venous distention is not a forward effect of left ventricular heart failure. It is a backward effect that occurs due to increased pressure in the right atrium and vena cava.
Correct Answer is D
Explanation
Choice A reason: This is not the agent that the nurse should question. Beta blockers are a class of medications that lower the blood pressure and heart rate by blocking the beta receptors in the heart and blood vessels. They can be used to treat hypertension, angina, heart failure, and arrhythmias. They do not cause edema or hyperkalemia.
Choice B reason: This is not the agent that the nurse should question. Alpha 2 agonists are a class of medications that lower the blood pressure by stimulating the alpha 2 receptors in the brain, which reduce the sympathetic nervous system activity. They can be used to treat hypertension, especially in patients with renal impairment. They do not cause edema or hyperkalemia.
Choice C reason: This is not the agent that the nurse should question. Calcium channel blockers are a class of medications that lower the blood pressure and heart rate by blocking the calcium channels in the heart and blood vessels, which cause vasodilation and reduced cardiac contractility. They can be used to treat hypertension, angina, and arrhythmias. They may cause edema, but not hyperkalemia.
Choice D reason: This is the agent that the nurse should question. Aldosterone antagonists are a class of medications that lower the blood pressure and reduce fluid retention by blocking the action of aldosterone, a hormone that regulates the sodium and potassium balance in the body. They can be used to treat hypertension and heart failure, especially in patients with low renin levels. However, they can cause hyperkalemia, which can be dangerous for the patient. The nurse should question the prescriber about the rationale for prescribing this agent and monitor the patient's potassium level closely.
