1. An older adult male is admitted with complications related to chronic obstructive pulmonary disease (COPD). He reports progressive dyspnea that worsens on exertion, and his weakness has increased over the past month. The nurse notes that he has dependent edema in both lower legs. Based on these assessment findings, which dietary instruction should the nurse provide?
- A. Restrict daily fluid intake
- B. Eat meals at the same time daily
- C. Maintain a low-protein diet
- D. Limit the intake of high-calorie foods
Correct answer: A
Rationale: Dependent edema in both lower legs is a sign of fluid overload, which can exacerbate dyspnea in patients with COPD. Restricting daily fluid intake can help reduce the edema and alleviate breathing difficulties. A low-protein diet is not necessary unless there are specific renal concerns. Eating meals at the same time daily or limiting high-calorie foods is not directly associated with addressing fluid overload and dyspnea in COPD patients.
2. A young adult who is hit with a baseball bat on the temporal area of the left skull is conscious when admitted to the ED and is transferred to the Neurological Unit to be monitored for signs of closed head injury. Which assessment finding is indicative of a developing epidural hematoma?
- A. Altered consciousness within the first 24 hours after injury
- B. Confusion immediately following the injury
- C. Headache that resolves quickly
- D. Brief loss of consciousness with a lucid interval
Correct answer: A
Rationale: The correct answer is A. Epidural hematoma often presents with a brief loss of consciousness followed by a lucid interval and then a rapid decline in consciousness. Therefore, altered consciousness within the first 24 hours after the injury is indicative of a developing epidural hematoma. Choices B, C, and D are incorrect because confusion immediately following the injury, headache that resolves quickly, and brief loss of consciousness with a lucid interval are not specific signs of epidural hematoma.
3. A client with chronic kidney disease has an arteriovenous (AV) fistula in the left forearm. Which observation by the nurse indicates that the fistula is patent?
- A. Distended, tortuous veins in the left hand
- B. The left radial pulse is 2+ bounding
- C. Auscultation of a thrill on the left forearm
- D. Assessment of a bruit on the left forearm
Correct answer: C
Rationale: Auscultation of a thrill on the left forearm is the correct observation indicating that the AV fistula is patent. A thrill is a palpable vibration or buzzing sensation felt over the fistula, indicating the presence of blood flow. Choices A, B, and D do not directly assess the patency of the fistula. Distended, tortuous veins in the left hand may indicate venous hypertension; a bounding radial pulse could suggest increased blood flow through an artery, but it does not confirm fistula patency; assessment of a bruit indicates turbulent blood flow, but it does not confirm patency.
4. A client receives a prescription for acetylcysteine (Mucomyst) 1.4 grams per nasogastric tube q4 hours. Acetylcysteine is available as a 10% solution (10 grams/100ml). How many ml of the 10% solution should the nurse administer per dose?
- A. 7
- B. 10
- C. 14
- D. 1.4 grams of acetylcysteine is equivalent to 14 ml of a 10% solution.
Correct answer: D
Rationale: To determine the amount of the 10% acetylcysteine solution to administer, convert the 1.4 grams to milligrams (1.4 grams = 1400 mg). Then, as the 10% solution contains 10 grams (10,000 mg) per 100 ml, it means there are 1000 mg of acetylcysteine in every 10 ml of the solution (10,000 mg / 100 ml = 100 mg/ml). Therefore, to administer 1400 mg (1.4 grams) of acetylcysteine, the nurse should give 14 ml of the 10% solution. Choices A, B, and C are incorrect as they do not accurately convert the amount of acetylcysteine to the corresponding volume of the 10% solution.
5. The healthcare provider prescribes amoxicillin (Amoxil) 1.5 grams PO daily, in equally divided doses to be administered every 8 hours. The medication is available in a bottle labeled, “Amoxicillin (Amoxil) suspension 200 mg/5 ml.†How many ml should the nurse administer every 8 hours? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
- A. 12.5
- B. 7.5
- C. 10.0
- D. 15.0
Correct answer: A
Rationale: To calculate the amount in ml that the nurse should administer every 8 hours, first, determine the amount of amoxicillin needed per dose. 1.5 grams daily divided by 3 doses equals 0.5 grams per dose. Since 0.5 grams is equivalent to 500 mg (1 gram = 1000 mg), and each 5 ml of the suspension contains 200 mg of amoxicillin, the nurse needs to administer (500 mg / 200 mg) * 5 ml = 12.5 ml every 8 hours. Therefore, the correct answer is 12.5 ml. Choices B, C, and D are incorrect because they do not reflect the accurate calculation based on the provided information.
