1. The client had gastric bypass surgery yesterday. Which intervention is most important for the nurse to implement during the first 24 postoperative hours?
- A. Insert an indwelling urinary catheter
- B. Monitor for the appearance of an incisional hernia
- C. Instruct the client to eat small frequent meals
- D. Measure hourly urinary output
Correct answer: D
Rationale: Monitoring hourly urinary output is crucial during the first 24 postoperative hours to assess kidney function, fluid balance, and early detection of complications like dehydration or inadequate kidney perfusion. Inserting an indwelling urinary catheter is not routinely necessary after gastric bypass surgery unless there are specific indications. Monitoring for an incisional hernia is important but not the highest priority in the immediate postoperative period. Instructing the client to eat small frequent meals is essential for long-term dietary management after gastric bypass surgery, but not the most critical intervention during the initial 24 hours.
2. 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.
3. An older client comes to the clinic with a family member. When the nurse attempts to take the client’s health history, the client does not respond to questions clearly. What action should the nurse implement first?
- A. Assess the surroundings for noise and distractions
- B. Provide a printed health history form
- C. Defer the health history until the client is less anxious
- D. Ask the family member to answer the questions
Correct answer: A
Rationale: The correct action for the nurse to implement first is to assess the surroundings for noise and distractions. This step is crucial as environmental factors can affect the client's ability to respond clearly. By minimizing noise and distractions, the nurse can create a more conducive environment for effective communication. Providing a printed form (Choice B) may help but addressing environmental factors should come first. Deferring the health history (Choice C) or asking the family member to answer the questions (Choice D) should not be the initial steps, as they do not directly address the issue of unclear communication with the client.
4. Which medication should the nurse anticipate administering to a client who is diagnosed with myxedema coma?
- A. Intravenous administration of thyroid hormones
- B. Oral administration of hypnotic agents
- C. Intravenous bolus of hydrocortisone
- D. Subcutaneous administration of vitamin K
Correct answer: A
Rationale: The correct answer is A: Intravenous administration of thyroid hormones. Myxedema coma is a severe form of hypothyroidism that necessitates immediate replacement of thyroid hormones. Administering thyroid hormones intravenously ensures rapid absorption and effectiveness in managing the condition. Choice B, oral administration of hypnotic agents, is incorrect as it does not address the primary issue of thyroid hormone deficiency in myxedema coma. Choice C, intravenous bolus of hydrocortisone, is not the appropriate treatment for myxedema coma as adrenal insufficiency is not the primary concern in this condition. Choice D, subcutaneous administration of vitamin K, is unrelated to the management of myxedema coma and does not address the underlying thyroid hormone deficiency that characterizes this condition.
5. After witnessing a preoperative client sign the surgical consent form, what are the legal implications of the nurse's signature on the client's form as a witness?
- A. The client voluntarily grants permission for the procedure to be done
- B. The surgeon has explained to the client why the surgery is necessary
- C. The client is competent to sign the consent without impairment of judgment
- D. The client understands the risks and benefits associated with the procedure
Correct answer: C
Rationale: The nurse's signature on the consent form signifies that the client is competent to sign the consent without impairment of judgment. This legal implication ensures that the client possesses the necessary capacity to make decisions about their healthcare. Choice A is incorrect because the nurse's signature does not imply the client's voluntary permission for the procedure. Choice B is incorrect as it pertains to the surgeon's responsibility, not the nurse's. Choice D is incorrect as the nurse's signature does not confirm the client's understanding of the risks and benefits associated with the procedure.
