Correct Answer: A

Rationale: The correct answer is A: Administer antibiotics. This is the best nursing action for a client with a wound infection because antibiotics are necessary to treat the infection at its source, targeting the bacteria causing the infection. Antibiotics help prevent the infection from spreading and promote healing. Explanation of why other choices are incorrect: B: Applying a sterile dressing is important for wound care but does not address the underlying infection. C: Monitoring blood pressure is important for overall patient assessment but does not directly treat the wound infection. D: Placing the client in a sitting position is not relevant to treating a wound infection.

Correct Answer: C

Rationale: The correct answer is C: Jaundice. In chronic liver disease, the liver's ability to process bilirubin is impaired, leading to jaundice. This is characterized by a yellowing of the skin and eyes. Monitoring for jaundice is crucial as it indicates liver dysfunction. Hypoglycemia (A) is not a typical complication of chronic liver disease. Hyperkalemia (B) is more commonly associated with kidney dysfunction. Anemia (D) can occur in liver disease but is not as specific a complication as jaundice. Therefore, monitoring for jaundice in a patient with chronic liver disease is essential for early detection and management of liver dysfunction.

Correct Answer: A

Rationale: The correct answer is A: Secure the airway. This is the highest priority for a nurse treating a client with a stab wound to the chest because airway management is crucial for ensuring the client can breathe effectively. If the airway is compromised, the client may not be able to oxygenate properly, leading to serious complications or even death. Administering oxygen (choice B) can help with oxygenation but is not as critical as ensuring the airway is clear. Turning the client (choice C) or applying an abdominal binder (choice D) are not appropriate actions for a stab wound to the chest and would not address the immediate life-threatening issue of airway compromise.

Correct Answer: C

Rationale: The correct answer is C: pernicious anemia. Pernicious anemia is caused by vitamin B12 deficiency, leading to impaired red blood cell production but does not directly affect clotting factors. Metastatic liver cancer (A) can cause liver dysfunction and decreased production of clotting factors, increasing bleeding risk. Gram-negative septicemia (B) can lead to disseminated intravascular coagulation and excessive bleeding. Iron-deficiency anemia (D) can result in microcytic red blood cells and decreased oxygen delivery but does not directly increase bleeding potential.

Correct Answer: D

Rationale: The correct answer is D because stopping medication once blood pressure returns to normal can lead to a relapse of hypertension. Step 1: Educate the patient that hypertension is a chronic condition requiring long-term management. Step 2: Explain the importance of continuing medication even when blood pressure is controlled. Step 3: Emphasize the risks of stopping medication abruptly. Other choices are incorrect because they promote positive behaviors for hypertension management: A: Monitoring blood pressure is essential. B: Taking medication consistently is crucial. C: Avoiding high-sodium foods helps control blood pressure.
