An adolescent client with meningococcal meningitis is receiving a continuous IV infusion of penicillin G. How many mL/hour should the nurse program the infusion pump to deliver?
- A. 83
- B. 85
- C. 87
- D. 90
Correct Answer: A
Rationale: The correct answer is A: 83. The pharmacy provided the infusion at 10 million units per liter, which requires a rate of 83 mL/hour. To calculate this, multiply the dosage by the volume of the IV solution and divide by the concentration of the IV solution in million units: 10 million units per liter x 8.3 L = 83 mL/hour. Choices B, C, and D are incorrect as they do not align with the calculation based on the given information.

A client with multiple sclerosis is admitted with an acute exacerbation. What is the nurse's priority action?
- A. Monitor the client's vital signs every hour.
- B. Assess for changes in the client's muscle strength.
- C. Administer prescribed corticosteroids to reduce inflammation.
- D. Educate the client on managing fatigue and preventing relapses.
Correct Answer: C
Rationale: The correct answer is C. Administering prescribed corticosteroids to reduce inflammation is the priority action when a client with multiple sclerosis is admitted with an acute exacerbation. Corticosteroids help manage symptoms during exacerbations and reduce inflammation. Monitoring vital signs and assessing muscle strength are important aspects of care but not the priority during an acute exacerbation. Educating the client on managing fatigue and preventing relapses is essential but can be addressed after the acute exacerbation has been managed.
A nurse receives a report on a client who is four hours post-total abdominal hysterectomy. The previous nurse reported that it was necessary to change the client's perineal pad hourly and that it is again saturated. The previous nurse also reports that the client's urinary output has decreased. Which action should the nurse implement first?
- A. Measure urinary output
- B. Assess for weakness or dizziness
- C. Increase IV fluids
- D. Check for vaginal bleeding
Correct Answer: D
Rationale: Saturation of the perineal pad after a hysterectomy suggests excessive vaginal bleeding, which must be addressed immediately. Assessing for vaginal bleeding is the priority in this situation as it can lead to hypovolemic shock. Measuring urinary output, assessing for weakness or dizziness, and increasing IV fluids are important interventions but checking for vaginal bleeding takes precedence due to the risk of hemorrhage post-hysterectomy.
The client is being taught about precautions with Coumadin therapy. The client should be instructed to avoid which over-the-counter medication?
- A. Non-steroidal anti-inflammatory drugs
- B. Cough medicines containing guaifenesin
- C. Histamine blockers
- D. Laxatives containing magnesium salts
Correct Answer: A
Rationale: The correct answer is A: Non-steroidal anti-inflammatory drugs (NSAIDs). NSAIDs can increase the risk of bleeding in clients taking Coumadin, which is an anticoagulant medication. Avoiding NSAIDs helps prevent potentially dangerous interactions with Coumadin. Choices B, C, and D are incorrect. Cough medicines with guaifenesin, histamine blockers, and laxatives containing magnesium salts do not typically have significant interactions with Coumadin therapy. Therefore, they are not the over-the-counter medications that the client needs to avoid while on Coumadin.
An adolescent with intellectual disability is admitted for refusing to complete oral hygiene. A behavior modification program is recommended. Which reinforcement is best?
- A. Unit tasks for each omitted teeth brushing.
- B. Candy for each successfully completed hygiene task.
- C. Privilege restriction for refusing hygiene tasks.
- D. Preferred activities or tokens for compliance.
Correct Answer: D
Rationale: The best reinforcement strategy in this scenario is providing preferred activities or tokens for compliance. Positive reinforcement is effective in behavior modification programs for individuals with intellectual disabilities. Offering preferred activities or tokens serves as a reward for completing the desired behavior, in this case, oral hygiene tasks. Choices A, B, and C do not focus on reinforcing the desired behavior with positive incentives. Choice A does not provide a positive reinforcement for compliance but rather focuses on the omission of a task. Choice B uses candy, which may not be ideal for oral hygiene. Choice C involves punishment rather than positive reinforcement.
A client is admitted to the hospital with a diagnosis of pneumonia. The client is prescribed intravenous antibiotics and oxygen therapy. Which assessment finding indicates that the client's condition is improving?
- A. Increased white blood cell count
- B. Crackles heard on lung auscultation
- C. Productive cough with green sputum
- D. Decreased respiratory rate from 24 to 18 breaths per minute
Correct Answer: D
Rationale: A decrease in respiratory rate indicates that the client's breathing is becoming more stable, which suggests an improvement in their condition. Respiratory rate is a critical indicator of respiratory status and oxygenation. Increased white blood cell count (choice A) suggests ongoing infection, crackles on lung auscultation (choice B) indicate fluid in the lungs, and productive cough with green sputum (choice C) may indicate persistent infection or airway inflammation, which do not necessarily reflect improvement in pneumonia.
