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

Answer and Explanation

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 C

Explanation

A. A toddler who has atopic dermatitis: Atopic dermatitis is a common chronic skin condition and does not increase the risk of child maltreatment. While it may require ongoing care, it is not associated with higher rates of abuse or neglect.

B. An only child: Being an only child is not a recognized risk factor for child maltreatment. Maltreatment risk is more closely related to caregiver stress, child vulnerability, and family dynamics rather than sibling status.

C. A school-age child who has cerebral palsy: Children with physical or developmental disabilities are at increased risk for maltreatment due to caregiver stress, dependency, and communication barriers. These children may be less able to protect themselves or report abuse, making them more vulnerable.

D. A child who was conceived by in vitro fertilization: Conception through assisted reproductive technology does not increase the risk of child maltreatment. These children are often highly desired and planned, which does not align with known risk factors for abuse or neglect.

A. Attach a blood pressure cuff to the client's upper arm B. Tell the client to expect a mild stinging sensation during the test. C. Assist the client to the orthopneic position. D. Instruct the client to remain as still as possible during the recording

Correct Answer is D

Explanation

A. Attach a blood pressure cuff to the client's upper arm: A blood pressure cuff is not required for obtaining a 12-lead ECG. Its use does not contribute to the quality of the ECG tracing and is unnecessary during this procedure.

B. Tell the client to expect a mild stinging sensation during the test: A 12-lead ECG is noninvasive and painless. Electrodes are placed on the skin with adhesive gel or pads, and clients typically feel no stinging. Providing accurate expectations helps reduce anxiety.

C. Assist the client to the orthopneic position: The orthopneic position is used to ease breathing in clients with respiratory distress. For a 12-lead ECG, the client should lie supine to ensure proper electrode placement and accurate readings.

D. Instruct the client to remain as still as possible during the recording: Movement can create artifacts on the ECG tracing, making interpretation difficult. Remaining still ensures accurate detection of cardiac electrical activity and reliable diagnostic results.
