Correct Answer: D

Rationale: The correct answer is D. A sudden weight increase may indicate fluid retention, a complication of TPN therapy that should be reported. Options A, B, and C are within normal ranges and do not directly relate to TPN therapy complications. A blood glucose level of 120 mg/dL is normal, a white blood cell count of 8,000/mm³ is within the normal range, and a temperature of 37.2°C (99°F) is also normal.

Correct Answer: B

Rationale: Encouraging the client to gradually resume self-care tasks with frequent rest periods is the best strategy to promote self-care for a client who experienced an acute myocardial infarction and is experiencing fatigue. This approach helps the client regain independence while managing fatigue. Asking family members to assist with all self-care tasks (Choice A) may hinder the client's independence. Instructing the client to remain in bed until fully rested (Choice C) may lead to deconditioning and dependency. Assigning assistive personnel to complete self-care tasks for the client (Choice D) does not empower the client to regain independence or actively participate in self-care.

Correct Answer: A

Rationale: Administering oxygen and seeking emergency help are crucial initial steps in managing a patient with suspected myocardial infarction (MI). Oxygen helps to improve oxygenation to the heart muscle, reducing its workload and preventing further damage. Calling for emergency help ensures timely access to advanced medical care, including interventions like thrombolytics. Monitoring vital signs and providing pain relief are important but secondary to the immediate need for oxygen and emergency assistance. Providing nitroglycerin and thrombolytics should be done under medical supervision and following appropriate protocols, not as the first step. Administering diuretics and altering the patient's diet are not indicated in the acute management of MI.

Correct Answer: A

Rationale: Correct answer: Monitoring for signs of infection and ensuring airway patency is crucial in managing a patient with a tracheostomy. This involves observing for redness, swelling, or discharge at the stoma site, as well as assessing for any signs of respiratory distress. Choice B, suctioning airway secretions and providing humidified air, is important for maintaining airway hygiene but may not be the initial assessment priority. Choice C, inspecting the stoma site and cleaning with saline, is part of routine tracheostomy care but does not address immediate assessment and management needs. Choice D, providing education on tracheostomy care, is valuable but not the primary action required in the assessment and management of a patient with a tracheostomy.

Correct Answer: A

Rationale: To administer a total of 300 mg daily (150 mg PO BID), the nurse should give 20 mL of the syrup. This is calculated by dividing the total daily dose (300 mg) by the concentration of the syrup (15 mg/mL), which equals 20 mL. Choice B (15 mL), C (25 mL), and D (10 mL) are incorrect because they do not accurately calculate the required volume of syrup needed to deliver the prescribed dose.
