1. An 8-year-old child who weighs 60 pounds receives an order for Polycilin (Ampicillin) suspension 25 mg/kg/day divided into a dose every 8 hours. The medication is labeled '125 mg/5 ml'. How many ml should the nurse administer per dose every 8 hours?
- A. 5
- B. 10
- C. 15
- D. 20
Correct answer: A
Rationale: Calculate the daily dose first: 60 pounds x 25 mg/kg = 1500 mg/day. Divide by 3 doses = 500 mg/dose. Convert to mL: (500 mg / 125 mg) x 5 ml = 20 ml. However, the question asks for the dose per administration every 8 hours, which is 1/3 of the daily dose. So, the correct calculation should be (20 ml / 3) = 6.67 ml, which rounds to 5 ml. Therefore, the correct answer is 5 ml. Choice B (10 ml) is incorrect because it doesn't consider the frequency of dosing. Choice C (15 ml) is incorrect as it overestimates the dose. Choice D (20 ml) is incorrect as it represents the total daily dose, not the dose per administration every 8 hours.
2. The nurse is preparing to administer an IM dose of vitamin B1 (Thiamine) to a male client experiencing acute alcohol withdrawal and peripheral neuritis. The client belligerently states, “What do you think you’re doing?†How should the nurse respond?
- A. “I cannot give you this medication until you calm down.â€
- B. “This shot will help relieve the pain in your feet.â€
- C. “Would you prefer to learn to administer your own shot?â€
- D. “You will feel calmer and less jittery after this shot.â€
Correct answer: B
Rationale: The correct response is to provide a relevant explanation to the client. Choice B, “This shot will help relieve the pain in your feet,†is the best answer because it directly addresses the client's concern about the purpose of the medication. By explaining the potential benefit of the injection, the nurse can alleviate the client's anxiety and increase their cooperation during the procedure. Choice A is incorrect as it dismisses the client's question and may escalate the situation. Choice C is not suitable as it deviates from addressing the client's immediate query. Choice D is incorrect because it fails to specifically address the client's concern regarding the medication's purpose.
3. The practical nurse (PN) is assigned to work with three registered nurses (RN) who are caring for neurologically compromised clients. The client with which change in status is best to assign to the PN?
- A. Diabetic ketoacidosis whose Glasgow Coma Scale score changed from 10 to 7
- B. Subdural hematoma whose blood pressure changed from 150/80 mmHg to 170/60 mmHg
- C. Myxedema coma whose blood pressure changed from 80/50 mmHg to 70/40 mmHg
- D. Viral meningitis whose temperature changed from 101° F (38.3 C) to 102° F (38.9C)
Correct answer: D
Rationale: The correct answer is D because viral meningitis with a slight increase in temperature is less acute and complex compared to the other conditions. This change in temperature does not indicate a critical or urgent situation requiring immediate attention or intervention beyond the scope of a practical nurse. Choices A, B, and C present more significant changes in health status such as a decrease in Glasgow Coma Scale score, an increase in intracranial pressure indicated by blood pressure changes, and a significant drop in blood pressure, respectively. These changes require closer monitoring and intervention by registered nurses due to the higher acuity and complexity of care needed for these conditions.
4. The nurse should explain to a client with lung cancer that pleurodesis is performed to achieve which expected outcome?
- A. Debulk tumor to maintain patency of air passages
- B. Relieve empyema after pneumonectomy
- C. Prevent the formation of effusion fluid
- D. Remove fluid from the intrapleural space
Correct answer: C
Rationale: The correct answer is C. Pleurodesis is a procedure used to prevent the re-accumulation of pleural effusion by creating adhesion between the pleurae. This helps prevent the formation of effusion fluid. Choices A, B, and D are incorrect because pleurodesis is not performed to debulk tumors, relieve empyema after pneumonectomy, or remove fluid from the intrapleural space. Understanding the purpose of pleurodesis is essential in providing accurate patient education and care.
5. What instruction should the nurse provide a pregnant client experiencing heartburn?
- A. Limit fluid intake between meals to prevent stomach over-distension
- B. Take an antacid at bedtime and when symptoms worsen
- C. Maintain an upright position for two hours after eating
- D. Eat small meals throughout the day to avoid a full stomach
Correct answer: D
Rationale: The correct answer is D: 'Eat small meals throughout the day to avoid a full stomach.' Heartburn is common in pregnancy due to increased intra-abdominal pressure and hormonal changes. Consuming small, frequent meals prevents the stomach from becoming overly full, reducing the likelihood of acid reflux and heartburn. Choice A is incorrect because limiting fluid intake between meals may not significantly impact heartburn. Choice B is not ideal as antacids should be taken as directed by a healthcare provider, not just at bedtime or when symptoms worsen. Choice C is less effective advice, as maintaining an upright position after eating may not directly address the root cause of heartburn.
