A client with diabetes is experiencing symptoms of hypoglycemia. What should the nurse administer first?
- A. 10 units of regular insulin subcutaneously
- B. 50 mL of 50% dextrose solution intravenously
- C. 1 mg of glucagon intramuscularly
- D. 15-20 grams of fast-acting carbohydrate orally
Correct Answer: D
Rationale: The correct answer is D: 15-20 grams of fast-acting carbohydrate orally. In hypoglycemia, the immediate goal is to raise blood glucose levels quickly. Fast-acting carbohydrates like glucose tablets or juice are the most effective and fastest way to raise blood sugar levels. Administering insulin (choice A) would further lower blood sugar levels. Intravenous dextrose (choice B) is appropriate for severe cases but may not be necessary as the first step. Glucagon (choice C) is typically used if the client is unconscious or unable to consume oral carbohydrates.
A nurse assesses a client who has a history of heart failure. Which question should the nurse ask to assess the extent of the client's heart failure?
- A. Do you have trouble breathing or chest pain?
- B. Are you able to walk upstairs without fatigue?
- C. Do you awake with breathlessness during the night?
- D. Do you have new-onset heaviness in your legs?
Correct Answer: B
Rationale: The correct answer is B because assessing the client's ability to walk upstairs without fatigue helps determine the extent of heart failure. This question assesses the client's functional capacity and exercise tolerance, which are key indicators of heart failure severity. If the client experiences fatigue while walking upstairs, it indicates decreased cardiac output and potential heart failure progression. Other choices are incorrect as they focus on symptoms (A), nocturnal dyspnea (C), and peripheral edema (D), which may be present in heart failure but do not directly assess the extent of heart failure like exercise tolerance does.
