1. A nurse is planning care for a client who has hypernatremia. Which of the following actions should the nurse include in the plan of care?
- A. Infuse hypotonic IV fluids.
- B. Implement a fluid restriction.
- C. Increase sodium intake.
- D. Administer sodium polystyrene sulfonate.
Correct answer: A
Rationale: The correct answer is to infuse hypotonic IV fluids. In hypernatremia, there is an elevated sodium concentration in the blood, and diluting it with hypotonic fluids helps to lower the sodium levels. Implementing a fluid restriction or increasing sodium intake would worsen hypernatremia by further concentrating sodium in the body. Administering sodium polystyrene sulfonate is used for treating hyperkalemia, not hypernatremia.
2. A patient uses an in-the-canal hearing aid. Which assessment is a priority?
- A. Eyeglass usage
- B. Cerumen buildup
- C. Type of physical exercise
- D. Excessive moisture problems
Correct answer: B
Rationale: When a patient uses an in-the-canal hearing aid, cerumen buildup is a critical issue that needs to be regularly assessed. Cerumen can easily block the sound passage and affect the functionality of the hearing aid. Assessing and managing cerumen buildup is a priority to ensure the proper functioning of the hearing aid. Eyeglass usage, type of physical exercise, and excessive moisture problems are not directly related to the specific issue of cerumen buildup in in-the-canal hearing aids, making them lower priority assessments in this context.
3. The mother of a 5-year-old boy with a myelomeningocele, who has developed a sensitivity to latex, is being taught by the nurse. Which response from his mother indicates a need for further teaching?
- A. He needs to wear a medical alert identification.
- B. I will need to inform his caregivers about his latex sensitivity.
- C. A product's label always indicates whether it is latex-free.
- D. He must avoid any contact with latex.
Correct answer: C
Rationale: Choice C, 'A product's label always indicates whether it is latex-free,' indicates a need for further teaching. Not all products are clearly labeled as latex-free; therefore, it is essential to verify with manufacturers and healthcare providers. Choices A, B, and D demonstrate appropriate understanding of managing latex sensitivity in the child. Wearing a medical alert identification (Choice A), informing caregivers (Choice B), and avoiding all contact with latex (Choice D) are all important aspects of managing a child's latex sensitivity.
4. After surgery to correct hypertrophic pyloric stenosis (HPS) in a 3-week-old infant who had been formula-fed, which postoperative feeding order is appropriate?
- A. Thickened formula 24 hours after surgery
- B. Withholding feedings for the first 24 hours
- C. Regular formula feeding within 24 hours after surgery
- D. Additional glucose feedings as desired after the first 24 hours
Correct answer: C
Rationale: After surgery for hypertrophic pyloric stenosis (HPS), it is appropriate to resume regular formula feeding within 24 hours postoperatively to promote recovery. Choice A, thickened formula after surgery, may be too heavy for the infant's digestive system at this early stage. Withholding feedings for the first 24 hours (Choice B) is not recommended as early feeding helps with recovery. Additional glucose feedings (Choice D) are not necessary and may not provide the balanced nutrition required after surgery.
5. Prior to administering morphine sulfate (Morphine), the nurse takes the client's vital signs. Based on which finding should the nurse withhold administration of the medication until the charge nurse is notified?
- A. Temperature of 100.8°F
- B. A pulse rate of 150 beats per minute
- C. A respiratory rate of 10 breaths per minute
- D. A blood pressure of 180/110
Correct answer: C
Rationale: The correct answer is C because a low respiratory rate is a critical concern when administering opioids like morphine, as they can suppress breathing. A high pulse rate (choice B) and high blood pressure (choice D) are not immediate contraindications for administering morphine. A slightly elevated temperature (choice A) may not necessarily require withholding morphine.
