1. A client with chronic alcoholism is admitted with a decreased serum magnesium level. Which snack option should the nurse recommend to this client?
- A. Cheddar cheese and crackers
- B. Carrot and celery sticks
- C. Beef bologna sausage slices
- D. Dry roasted almonds
Correct answer: D
Rationale: Dry roasted almonds are the most suitable snack option for a client with chronic alcoholism and a decreased serum magnesium level because they are high in magnesium. Magnesium is essential in addressing the deficiency. Cheddar cheese and crackers (Choice A) do not contain as much magnesium as almonds. Carrot and celery sticks (Choice B) are healthy choices but do not provide a significant amount of magnesium. Beef bologna sausage slices (Choice C) are not a good choice as processed meats are not rich in magnesium.
2. A client who is bleeding after a vaginal delivery receives a prescription for methylergonovine (Methergine) 0.4 mg IM every 2 hours, not to exceed 5 doses. The medication is available in ampules containing 0.2 mg/ml. What is the maximum dosage in mg that the nurse should administer to this client? (Enter numeric value only)
- A. 2
- B. 3
- C. 4
- D. 5
Correct answer: A
Rationale: To calculate the maximum dosage in mg that the nurse should administer, multiply the dose per administration (0.4 mg) by the maximum number of doses allowed (5 doses): 0.4 mg/dose * 5 doses = 2 mg. Therefore, the nurse should administer a maximum dosage of 2 mg to the client. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.
3. 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.
4. A 5-week-old infant who developed projectile vomiting over the last two weeks is diagnosed with hypertrophic pyloric stenosis. Which intervention should the nurse plan to implement?
- A. Instruct the mother to give the child sugar water only
- B. Maintain intravenous fluid therapy per prescription
- C. Provide Pedialyte feedings via the nasogastric tube
- D. Offer the infant Pedialyte feedings every 2 hours
Correct answer: B
Rationale: Maintaining intravenous fluid therapy is crucial for managing dehydration and electrolyte imbalances caused by the vomiting in hypertrophic pyloric stenosis. Instructing the mother to give sugar water only (Choice A) is not appropriate as it does not address the dehydration and electrolyte imbalances adequately. Providing Pedialyte feedings via the nasogastric tube (Choice C) may not be sufficient to manage the severe fluid and electrolyte losses caused by the condition. Offering Pedialyte feedings every 2 hours (Choice D) may not be as effective as maintaining intravenous fluid therapy, especially in cases where rapid rehydration is necessary.
5. A postoperative client returns to the nursing unit following a ureterolithotomy via a flank incision. Which potential nursing problem has the highest priority when planning nursing care for this client?
- A. Ineffective airway clearance
- B. Altered nutrition less than body requirements
- C. Fluid volume excess
- D. Activity intolerance
Correct answer: A
Rationale: In this scenario, the highest priority nursing problem for the postoperative client following a ureterolithotomy via a flank incision is ineffective airway clearance. After surgery, there is a risk of airway obstruction due to factors like anesthesia, positioning during surgery, or the presence of secretions. Maintaining a clear airway is crucial to prevent respiratory complications, such as atelectasis or pneumonia. Altered nutrition, fluid volume excess, and activity intolerance are important considerations but are secondary to the immediate threat of compromised airway clearance in the postoperative period.
