What clinical finding is associated with hydralazine toxicity?

A. Hyperkalemia: Milrinone primarily affects cardiac contractility and vascular tone and does not typically cause hyperkalemia. Elevated potassium levels would more likely be related to other medications, renal dysfunction, or underlying conditions rather than milrinone therapy.

B. Hypertension: Milrinone is a phosphodiesterase-3 inhibitor that causes vasodilation, which generally lowers blood pressure rather than increases it. Hypertension is not a common adverse effect of long-term milrinone use.

C. Calf pain: Calf pain could indicate deep vein thrombosis or musculoskeletal issues, but it is not a recognized adverse effect of milrinone. While it should be assessed, it is unlikely related to the drug.

D. Heart palpitations: Milrinone can cause arrhythmias, including palpitations, ventricular tachycardia, or atrial fibrillation, especially with long-term use. The presence of palpitations is a significant adverse effect and warrants immediate assessment and possible adjustment of therapy.

A. A client with an emphysema exacerbation: Clients experiencing an acute exacerbation of emphysema often have increased airway obstruction and difficulty breathing. A small volume nebulizer delivers bronchodilators directly to the lungs, providing rapid relief of bronchospasm and improving oxygenation.

B. A client experiencing an asthma attack: During an asthma attack, airway constriction can be severe. An SVN allows precise delivery of inhaled medications like albuterol, which rapidly dilate the airways and reduce respiratory distress, making it essential for urgent intervention.

C. A client with a common cold and fever: A common cold typically causes mild upper respiratory symptoms such as congestion and runny nose. SVNs are not indicated for routine cold management, as bronchodilator therapy is not necessary in uncomplicated viral infections.

D. A client with significant respiratory symptoms: Clients showing significant respiratory distress, regardless of underlying cause, may benefit from an SVN to administer medications that relieve bronchospasm, decrease airway inflammation, and improve ventilation rapidly.

E. A client with mild seasonal allergies: Mild seasonal allergies usually present with sneezing, watery eyes, and nasal congestion without significant airway obstruction. SVNs are not indicated for mild allergic symptoms, as oral or intranasal antihistamines are sufficient.
