Question 1 of 5
A nurse is preparing to administer liquid famotidine 20 mg PO every 6 hr for GERD. Available is famotidine 40 mg/5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale: Volume = Desired dose / Available concentration per ml. Available concentration = 40 mg / 5 ml = 8 mg/ml. Desired dose = 20 mg. Volume = 20 mg / 8 mg/ml = 2.5 ml.
Question 2 of 5
The nurse is assisting with nutrition teaching for a patient who voices concern over adjusting to a diabetic diet. Which response by the nurse about medical nutrition therapy is correct?
Correct Answer: C
Rationale: Medical nutrition therapy for diabetes involves creating a well-balanced, individualized meal plan that meets the patient's nutritional needs while helping to manage blood glucose levels.

Question 4 of 5
The nurse recognizes the patient is demonstrating signs of diabetic ketoacidosis (DKA). Which findings support this recognition? Select all that apply.
Correct Answer: A,C,F,G
Rationale: A. Acetone breath, characterized by a fruity or acetone-like odor on the patient's breath, is a classic sign of DKA. In addition, Kussmaul respirations, which are deep and labored breathing patterns, can occur as the body attempts to compensate for metabolic acidosis in DKA. C. Nausea and vomiting are common symptoms of DKA and can occur due to metabolic acidosis, electrolyte imbalances, and gastrointestinal disturbances associated with the condition. F. Tachycardia and hypotension are signs of hemodynamic instability, which can occur in severe cases of DKA due to dehydration, electrolyte imbalances, and the systemic effects of metabolic acidosis. G. Turning off an insulin pump can lead to insulin deficiency, which is a precipitating factor for DKA, particularly in patients with type 1 diabetes who rely on continuous insulin therapy.

Question 5 of 5
A patient is admitted to a respiratory unit with a diagnosis of bacterial pneumonia. Findings include a fever and a weak, congested-sounding cough with moist crackles throughout the lung fields. How should the nurse prioritize care?
Correct Answer: B
Rationale: The inability to clear the airway is a critical issue. This patient has a weak, congested-sounding cough and moist crackles, indicating that secretions are present and not being effectively cleared. This can lead to airway obstruction, decreased oxygenation, and further respiratory complications. Clearing the airway is a top priority to ensure the patient can breathe properly and prevent further deterioration.
