1. 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.
2. In what order should the nurse perform the steps of a surgical hand scrub prior to entering the operating room?
- A. Rinse from the fingertips to the elbow
- B. Scrape under the nails with a nail pick
- C. Use a soapy brush to scrub the hands
- D. Cleanse the arm with a lathered brush
Correct answer: B
Rationale: The correct order for performing a surgical hand scrub is to first scrape under the nails with a nail pick, then scrub the hands using a soapy brush, cleanse the arms, and finally rinse. This sequence ensures thorough cleaning and minimizes the risk of contamination. Choice A is incorrect because rinsing should be the final step, not the first. Choice C is incorrect as scrubbing the hands comes after scraping under the nails. Choice D is incorrect as cleansing the arms should follow hand scrubbing, not precede it.
3. When should the nurse conduct an Allen’s test?
- A. When obtaining pulmonary artery pressures
- B. To assess for the presence of a deep vein thrombus in the leg
- C. Just before arterial blood gases are drawn peripherally
- D. Prior to attempting a cardiac output calculation
Correct answer: C
Rationale: The correct time to conduct an Allen’s test is just before arterial blood gases are drawn peripherally. This test is performed to assess the adequacy of collateral circulation in the hand before obtaining arterial blood gases. Choice A is incorrect because an Allen’s test is not specifically done when obtaining pulmonary artery pressures. Choice B is incorrect because an Allen’s test is not used to assess deep vein thrombosis. Choice D is incorrect because an Allen’s test is not done specifically before attempting a cardiac output calculation.
4. The client who had a below-the-knee (BKA) amputation is being prepared for discharge to home. Which recommendation should the nurse provide this client?
- A. Inspect skin for redness
- B. Use a residual limb shrinker
- C. Apply alcohol to the stump after bathing
- D. Wash the stump with soap and water
Correct answer: D
Rationale: The correct recommendation for a client with a below-the-knee amputation preparing for discharge is to wash the stump with soap and water. This helps maintain cleanliness and prevent infection. Inspecting the skin for redness is important to monitor for signs of infection, but it is not a specific recommendation for a BKA amputation. Using a residual limb shrinker can aid in shaping and reducing swelling in the residual limb but is not usually done immediately after a BKA amputation. Applying alcohol to the stump after bathing is not recommended as it can lead to skin irritation and dryness.
5. A 3-year-old boy was successfully toilet trained prior to his admission to the hospital for injuries sustained from a fall. His parents are very concerned that the child has regressed in his toileting behaviors. Which information should the nurse provide to the parents?
- A. Children usually resume their toileting behaviors when they leave the hospital
- B. A retraining program will need to be initiated when the child returns home
- C. Diapering will be provided since hospitalization is stressful to preschoolers
- D. A potty chair should be brought from home so he can maintain his toileting skills
Correct answer: A
Rationale: Children often regress in toileting behaviors during hospitalization due to stress and changes in routine. However, they usually resume normal behaviors once they are discharged and back in their familiar environment. Providing reassurance to the parents that the child is likely to return to his previous toileting habits after leaving the hospital can help alleviate their concerns. Choices B, C, and D are incorrect because they do not address the normal pattern of behavior regression and recovery in toileting skills associated with hospitalization.
