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. Hyperthermia: Cocaine is a stimulant that increases sympathetic nervous system activity, leading to elevated body temperature, tachycardia, and hypertension. Hyperthermia is a common acute effect of cocaine use.
B. Increased appetite: Cocaine typically suppresses appetite due to its stimulant effects on the central nervous system. Clients often experience decreased hunger rather than increased appetite.
C. Sedation: Cocaine use generally causes CNS stimulation, resulting in agitation, restlessness, or insomnia rather than sedation. Sedative effects are more characteristic of depressant substances.
D. Hypotension: Cocaine causes vasoconstriction and sympathetic stimulation, which usually leads to elevated blood pressure. Hypotension is not expected and may indicate a complication or co-ingestion of another substance.
Correct Answer is D
Explanation
A. “Limit your caffeine intake to 700 milligrams per day.”: Caffeine intake during pregnancy should be limited to about 200 milligrams per day. Higher amounts are associated with increased risks such as miscarriage and low birth weight, making this recommendation inaccurate.
B. “Eat 40 milligrams of protein-rich foods per day.”: Protein requirements during pregnancy are measured in grams, not milligrams. Pregnant clients typically need about 71 grams of protein per day, so this reflects an incorrect unit and inadequate intake.
C. “Increase your dietary intake by 500 calories per day.”: Caloric needs during the first trimester generally do not increase significantly. An additional 300–450 calories per day is usually recommended later in pregnancy, making this advice inappropriate at 12 weeks’ gestation.
D. “Consume 600 micrograms of folic acid per day.”: A daily intake of 600 micrograms of folic acid is recommended during pregnancy to support fetal neural tube development. Adequate folic acid intake reduces the risk of neural tube defects, especially in early pregnancy.
