A nurse is collecting data from a client who has hypokalemia and recently started potassium chloride supplements. Which of the following findings indicates a positive response to the intervention?
Reduced anxiety
Normal sinus rhythm
Decreased urinary output
Decreased blood pressure
The Correct Answer is B
A. Reduced anxiety: While anxiety may improve with overall health stabilization, it is not a direct indicator of potassium replacement effectiveness. Potassium primarily affects neuromuscular and cardiac function rather than emotional state.
B. Normal sinus rhythm: Hypokalemia can cause cardiac arrhythmias. The presence of a normal sinus rhythm indicates that potassium levels have been corrected and the heart’s electrical activity is stabilized, reflecting a positive response to supplementation.
C. Decreased urinary output: Changes in urinary output are not a direct measure of potassium replacement effectiveness and may indicate other complications, such as renal impairment or fluid imbalance.
D. Decreased blood pressure: Blood pressure changes are not a direct outcome of potassium supplementation and could suggest unrelated cardiovascular issues. Normalization of cardiac rhythm is a more specific indicator of intervention success.

Correct Answer is A
Explanation
A. Wheat bread: Wheat bread is relatively low in potassium compared with fruits, vegetables, and juices. It is generally appropriate for clients who require potassium restriction due to renal disease or certain electrolyte imbalances.
B. Orange juice: Orange juice is high in potassium and can significantly increase serum potassium levels. It is commonly restricted in clients who must limit potassium intake to prevent hyperkalemia.
C. Sweet potato: Sweet potatoes contain a high amount of potassium, especially when baked or mashed. They are typically avoided in low-potassium diets because they can rapidly elevate potassium levels.
D. Canned green beans: Although canned vegetables have less potassium than fresh ones due to processing, green beans still contain more potassium than wheat bread. They are not the lowest potassium option.
Correct Answer is C
Explanation
A. Peeling of the hands and feet: Desquamation of the hands and feet is commonly associated with conditions such as Kawasaki disease or scarlet fever during the healing phase. It is not a typical manifestation of pertussis.
B. Koplik spots: Koplik spots are small white lesions on the buccal mucosa that are characteristic of measles. They are not seen in pertussis and point toward a different viral illness.
C. Paroxysmal cough: Pertussis is characterized by severe, repetitive coughing spells that occur in rapid succession. These paroxysmal coughs may be followed by a high-pitched inspiratory “whoop” and can lead to vomiting or exhaustion.
D. Beefy, red tongue: A beefy red tongue is commonly associated with scarlet fever or other streptococcal infections. It is not a defining feature of pertussis.
