Correct Answer: C

Rationale: Following a total hip arthroplasty, the client should be instructed to restrict hip flexion past 90 degrees to prevent dislocation of the prosthesis. Restricting flexion past 120 degrees is excessive and could lead to complications. Therefore, the nurse should verify this prescription with the provider to ensure the client's safety and proper postoperative care.

Correct Answer: A

Rationale: To calculate the mL of albuterol syrup needed per dose, first, determine how many milligrams are in the prescribed dose: 1.6 mg. Next, set up a proportion to find the equivalent mL for 1.6 mg using the given concentration of 2 mg/5mL. The calculation is: (1.6 mg x 5 mL) / 2 mg = 4 mL. Therefore, the correct answer is 4 mL to administer per dose.

Correct Answer: D

Rationale: Repositioning the endotracheal tube to the opposite side of the mouth daily is not a standard practice and can increase the risk of complications, such as accidental extubation or damage to the airway. The endotracheal tube should remain in the initial correct position to ensure proper ventilation and prevent harm to the client. Elevating the head of the bed, verifying ventilator settings, and administering pantoprazole as prescribed are all appropriate interventions to prevent complications in a client receiving positive-pressure mechanical ventilation.

Correct Answer: A

Rationale: When a client receives a competitive neuromuscular blocking agent, it can lead to respiratory muscle paralysis. Placing a bag valve mask device at the client's bedside is crucial for providing immediate respiratory support in case of respiratory depression or failure. This device allows manual ventilation by squeezing the bag to deliver breaths to the client. The other options, such as a defibrillator machine, chest tube equipment, and central venous catheter tray, are not directly related to managing respiratory complications associated with neuromuscular blockade.

Correct Answer: D

Rationale: Pyrazinamide can cause gastrointestinal upset and is best taken with a full glass of water to minimize irritation to the stomach lining. This instruction helps reduce the risk of adverse effects associated with pyrazinamide. Options A and C are not directly related to the medication regimen for tuberculosis. While sputum testing is important, the frequency mentioned in option B is not required every two weeks.
