Nokea
A nurse is assisting with the care of a client who has a closed-chest tube drainage system. Which of the following actions should the nurse take?
- A. Replace the unit when the drainage chamber is full.
- B. Clamp the tube for 30 min every 8 hr.
- C. Pin the tubing to the client's bed sheets.
- D. Monitor for at least 150 mL of drainage every hour.
Correct Answer: A
Rationale: Replacing the unit when full maintains system function. Clamping risks tension pneumothorax, pinning can dislodge tubing, and 150 mL/hr is excessive and not a standard expectation.

A nurse is preparing to administer filgrastim 6 mcg/kg subcutaneously to a client who weighs 110 lb. Available is filgrastim solution for injection 480 mcg/0.8 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
- A. 0.3 mL
- B. 0.4 mL
- C. 0.5 mL
- D. 0.6 mL
Correct Answer: C
Rationale: To calculate the correct dose, convert the client's weight from pounds to kilograms (110 lb ÷ 2.2 = 50 kg). Filgrastim is dosed at 6 mcg/kg, so 6 mcg/kg × 50 kg = 300 mcg needed. The available concentration is 480 mcg in 0.8 mL. Set up the proportion: (300 mcg ÷ 480 mcg) × 0.8 mL = 0.5 mL. Option A (0.3 mL) underdoses at 180 mcg, Option B (0.4 mL) gives 240 mcg, and Option D (0.6 mL) overdoses at 360 mcg. Option C (0.5 mL) delivers exactly 300 mcg, matching the prescribed dose. Rounding to the nearest tenth, 0.5 mL is correct with no trailing zero, adhering to medication safety standards. This calculation ensures therapeutic efficacy (e.g., boosting white blood cells) while minimizing risks like overdose-related bone pain or underdose-related infection susceptibility, making C the precise and safe choice.
A nurse is reinforcing teaching with a client who wants to lose 0.9 kg (2 lb) of body fat per week. The nurse knows that 0.45 kg (1 lb) of body fat is equal to 3500 calories. The nurse should instruct the client to reduce his daily caloric intake by how many calories?
Correct Answer: 1000
Rationale: Calculation: 2 lb × 3,500 cal/lb = 7,000 cal/week; 7,000 ÷ 7 = 1,000 cal/day reduction achieves the weight loss goal.
A nurse is reinforcing teaching with an older adult client who is postoperative following a transurethral resection of the prostate. Which of the following statements should the nurse include in the teaching?
- A. You should take ibuprofen for discomfort.
- B. You should wait 6 weeks before resuming sexual intercourse.
- C. You may tub bathe until the catheter is removed.
- D. You may drive after 1 week.
- E. Avoid drinking water.
- F. Expect bright red urine indefinitely.
- G. Ignore bladder spasms.
Correct Answer: B
Rationale: Waiting 6 weeks allows healing; ibuprofen may increase bleeding, tub baths risk infection, and driving depends on recovery.
A nurse is assisting in the plan of care for a client who has constipation after receiving opioid medication for incisional pain. Which of the following actions should the nurse take first?
- A. Encourage the client to increase oral intake of fluids.
- B. Auscultate the client's abdomen for bowel sounds.
- C. Provide the client privacy with a set time to defecate.
- D. Administer a fiber-based laxative to the client.
- E. Increase physical activity.
- F. Check medication history.
- G. Apply heat to the abdomen.
Correct Answer: B
Rationale: Auscultating bowel sounds assesses the underlying issue (e.g., ileus) before interventions like fluids or laxatives.
A nurse is reinforcing discharge teaching for a client who had a cerebrovascular accident (CVA) and requires assistance to perform their ADLs. Which of the following statements should the nurse provide?
- A. You will not become fatigued when you use assistive devices.
- B. Plan to hire a home care aid to perform all of your ADLs.
- C. Install grab bars in your shower to assist with your balance.
- D. Place a towel in the shower to prevent slipping
Correct Answer: C
Rationale: Grab bars enhance safety and independence in the shower post-CVA. Fatigue is possible, full assistance isn't always needed, and a towel could be a slip hazard.
