Correct Answer: B

Rationale: The correct answer is B: Anti-infectives. Anti-infective agents, such as antibiotics, are essential in treating septic shock as they can eliminate bacteria and halt the progression of the condition by stopping the production of endotoxins. Antihypertensives (Choice A) are used to lower blood pressure, antihistamines (Choice C) are used to treat allergic reactions, and anticholesteremics (Choice D) are used to lower cholesterol levels. However, none of these drug classes directly address the bacterial infection that underlies septic shock.

Correct Answer: B

Rationale: To calculate the volume to be administered for 35 mg of ceftazidime, divide the prescribed dose by the concentration: 35 mg / 100 mg/ml = 0.35 ml. Rounding off, the nurse should administer 0.4 ml for each dose. Choice A is incorrect as it doesn't consider rounding off. Choice C is incorrect because it's not the correct calculation. Choice D is incorrect as it doesn't reflect the accurate volume needed.

Correct Answer: B

Rationale: In this scenario, the most critical intervention is to obtain a wound swab for culture and sensitivity. This will help identify the causative organism present in the wound, enabling healthcare providers to prescribe the appropriate treatment. Initiating contact isolation (Choice A) may be necessary in certain situations but is not the priority in this case where infection is suspected. Assessing the temperature (Choice C) is important for monitoring the client's condition but does not address the underlying cause. Using alcohol-based solutions for hand hygiene (Choice D) is a standard practice for infection control but does not directly address the client's specific condition of a postoperative wound with evisceration and elevated temperature.

Correct Answer: B

Rationale: Confusion and altered mental status in a client with cirrhosis and associated ascites and jaundice are indicative of hepatic encephalopathy, a serious complication that requires immediate intervention. This condition can progress rapidly and lead to coma if not addressed promptly. Peripheral edema (choice A) and increased abdominal girth (choice C) are common manifestations of fluid retention in cirrhosis but may not require immediate intervention unless severe. Yellowing of the skin (choice D) is a classic sign of jaundice, which is already known in this client and may not necessitate immediate intervention unless associated with other concerning symptoms.

Correct Answer: C

Rationale: The correct answer is C. Use of accessory muscles is the most concerning finding in a client with COPD experiencing an exacerbation. This indicates increased work of breathing and can be a sign of respiratory failure, requiring immediate intervention. Oxygen saturation of 90% is low but not as concerning as the increased work of breathing. A respiratory rate of 24 breaths per minute can be within normal limits. Inspiratory crackles may be present in COPD due to airway inflammation but are not as concerning as the use of accessory muscles.
