Correct Answer: A

Rationale: Corrected Question: To assess a patient with a tracheostomy, the healthcare professional should primarily focus on monitoring for infection and ensuring the airway remains patent. Choice A is the correct answer as these actions are crucial for tracheostomy management. Suctioning airway secretions and providing humidified oxygen (Choice B) are interventions that may be necessary based on the assessment findings but are not the initial assessment steps. Similarly, cleaning the stoma and changing tracheostomy ties (Choice C) are important aspects of tracheostomy care but do not specifically address the initial assessment. Educating the patient on tracheostomy care (Choice D) is important, but it is not the primary assessment action needed when assessing 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.

Correct Answer: D

Rationale: Correct Answer: Green leafy vegetables - Green leafy vegetables are high in vitamin K, which can interfere with the effectiveness of warfarin. Tomatoes, apples, and broccoli are not contraindicated with warfarin therapy. While they are healthy choices, they do not have a significant impact on warfarin's effectiveness.

Correct Answer: A

Rationale: The correct answer is A: Diabetic ketoacidosis and dehydration. Untreated hyperglycemia can lead to diabetic ketoacidosis, a serious complication characterized by high blood sugar, the presence of ketones in the urine, and acidosis. Dehydration is also a common complication of untreated hyperglycemia. Choices B, C, and D are incorrect because hypoglycemia and hypertension are not typical complications of untreated hyperglycemia. Infection and liver failure, as well as pulmonary edema and electrolyte imbalance, are also not direct complications of untreated hyperglycemia.

Correct Answer: B

Rationale: The most important point to emphasize when teaching a client with diabetes about insulin administration is to administer insulin before meals as prescribed. This is crucial for maintaining proper blood sugar control throughout the day. Choice A is incorrect because blood sugar levels need to be monitored multiple times a day, not just once in the morning. Choice C is incorrect because insulin should be administered according to the prescribed schedule, not only when feeling unwell. Choice D is incorrect because blood sugar monitoring should be done at various times during the day, not just in the evening.
