Which nursing assessment confirms that the angiotensin II receptor blocker (ARB) that a patient is taking is effective?

Choice A reason: This is not a symptom that would indicate withholding a nonselective beta-adrenergic blocker. Hyperglycemia is a high level of glucose in the blood, which can be caused by diabetes or other conditions. Nonselective beta-adrenergic blockers do not affect blood glucose levels directly, but they may mask the signs of hypoglycemia (low blood glucose) in diabetic patients.

Choice B reason: This is not a symptom that would indicate withholding a nonselective beta-adrenergic blocker. Dizziness is a common side effect of many medications, especially those that lower blood pressure. Nonselective beta-adrenergic blockers can cause dizziness by reducing the heart rate and cardiac output, but this is usually mild and transient.

Choice C reason: This is not a symptom that would indicate withholding a nonselective beta-adrenergic blocker. Peripheral edema is swelling of the ankles, feet, or legs, which can be caused by heart failure, kidney disease, or venous insufficiency. Nonselective beta-adrenergic blockers do not cause peripheral edema, but they may worsen it in patients with heart failure.

Choice D reason: This is a symptom that would indicate withholding a nonselective beta-adrenergic blocker. Wheezing is a high-pitched sound that occurs when breathing is obstructed, usually due to asthma or chronic obstructive pulmonary disease (COPD). Nonselective beta-adrenergic blockers can aggravate or cause wheezing by blocking the beta-2 receptors in the lungs, which normally cause bronchodilation (widening of the airways). Therefore, nonselective beta-adrenergic blockers are contraindicated in patients with asthma or COPD.

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.
