Correct Answer: A

Rationale: For a 7-year-old client recovering from partial-thickness burns with sensitivity to loud noises and bright lights, along with a tendency to become overstimulated, the best teaching environment would be the client's room. This setting provides a familiar and comforting space where the client feels secure and less exposed to external stimuli that may trigger discomfort or anxiety. Being in her own room allows the client to focus better, feel more at ease, and have better communication with the nurse without distractions from bright lights, loud noises, or other people around. This controlled and peaceful environment contributes to a more effective teaching and learning experience for the client, promoting better understanding and retention of information.

Correct Answer: C

Rationale: Enalapril is an angiotensin-converting enzyme (ACE) inhibitor commonly used in the treatment of heart failure. One of the potential adverse effects of ACE inhibitors, including enalapril, is hypotension or low blood pressure. This is especially a concern following the initial administration of the drug, as it can cause a significant drop in blood pressure. Nurses should assess the patient for signs and symptoms of hypotension, such as dizziness, light-headedness, weakness, or fainting, after starting enalapril therapy. Monitoring blood pressure regularly and educating the patient about the possibility of low blood pressure is important to ensure patient safety and optimal outcomes.

Correct Answer: D

Rationale: An isoelectric ST segment on an electrocardiogram can indicate myocardial ischemia or injury, which can lead to a decrease in perfusion to the heart muscle. This finding suggests an increased risk of inadequate blood flow to the heart, potentially resulting in further complications such as a myocardial infarction or altered perfusion to other organs. In a client with lower extremity edema and shortness of breath, identifying this ECG finding is crucial for early intervention and monitoring to prevent further deterioration in perfusion status.

Correct Answer: B

Rationale: A client with sepsis and a temperature of 40°C is likely experiencing a systemic inflammatory response, which can lead to a variety of dysrhythmias. In this case, the client is more likely to develop a tachydysrhythmia (fast heart rate) due to the body's response to the infection. Sepsis can result in an increase in heart rate as the body tries to maintain adequate perfusion to vital organs in response to the inflammatory process. Tachydysrhythmias such as supraventricular tachycardia or atrial fibrillation are commonly observed in septic patients with high fevers.
