Correct Answer: C

Rationale: Shortness of breath is the most concerning assessment finding in a client with a history of atrial fibrillation. It can indicate a worsening of the condition, pulmonary edema, or the development of a complication such as heart failure. A blood pressure of 150/90 mmHg, while elevated, is not as immediately concerning as respiratory distress in this context. An irregular heart rhythm is expected in atrial fibrillation and may not necessarily be a new or concerning finding. Fatigue is a common symptom in atrial fibrillation but is not as acutely concerning as shortness of breath, which may indicate compromised oxygenation and circulation.

Correct Answer: A

Rationale: In a case of hyperemesis gravidarum, the priority nursing diagnosis should be addressing the Fluid volume deficit. This condition can lead to serious complications such as electrolyte imbalances and dehydration, which can endanger both the mother and the fetus if not managed promptly. Altered nutrition: less than body requirements is important but addressing the fluid volume deficit takes precedence as it poses an immediate threat. Anxiety related to new situational crisis and Activity intolerance related to fatigue are valid concerns, but they are secondary to the critical issue of fluid volume deficit in this scenario.

Correct Answer: A

Rationale: A pericardial friction rub is characterized by a scratching sound that occurs during both systole and diastole. It becomes more distinct when the client is sitting up and leaning forward. This indicates an inflammation of the pericardial sac rubbing against the layers of the heart. Heart murmurs (choice B) are abnormal heart sounds caused by turbulent blood flow, not by friction like in a pericardial rub. S3 and S4 heart sounds (choices C and D) are additional heart sounds related to abnormal ventricular filling, not to pericardial friction rubs.

Correct Answer: C

Rationale: In this scenario, the nurse should instruct the client to take deep rhythmic breaths as a non-pharmacological pain management method. Deep breathing can help the client relax, reduce stress, and manage pain effectively. Applying heat or ice for prolonged periods can lead to tissue damage. Removing distractions can be helpful for promoting relaxation but may not directly address the pain itself.

Correct Answer: C

Rationale: The correct answer is C: Identifying the client's medication allergies. This is the priority action before administering any medication to prevent allergic reactions or adverse effects. Teaching the client about the medication's purpose is important for client understanding but not as critical as ensuring the absence of allergies. While giving medication at the prescribed time is crucial, verifying allergies takes precedence to ensure patient safety. Documenting the client's anxiety level is relevant for holistic care but is not the priority compared to ensuring safe medication administration.
