1. A client who received a renal transplant three months ago is readmitted to the acute care unit with signs of graft rejection. While taking the client's history, the nurse determines the client has been self-administering St. John's wort, an herbal preparation, on the advice of a friend. What information is most significant about this finding?
- A. Wort can decrease plasma concentration of Cyclospora
- B. Wort can decrease plasma concentration of Tacrolimus
- C. Wort can decrease plasma concentration of Cyclosporine
- D. Wort can decrease plasma concentration of Mycophenolate
Correct answer: C
Rationale: The most significant information about the client self-administering St. John's wort, an herbal preparation, is that it can decrease the plasma concentration of Cyclosporine. St. John's wort is known to reduce the efficacy of Cyclosporine, which is a common immunosuppressant drug used to prevent transplant rejection. Choices A, B, and D are incorrect because St. John's wort does not affect the plasma concentration of Cyclospora, Tacrolimus, or Mycophenolate.
2. The nurse is caring for a patient diagnosed with diabetes. Which task will the nurse assign to the nursing assistive personnel?
- A. Providing nail care
- B. Teaching foot care
- C. Making the patient's bed
- D. Determining aspiration risk
Correct answer: C
Rationale: The correct answer is making the patient's bed. Delegating bed-making tasks to nursing assistive personnel is appropriate as it falls within their scope of practice and helps free up the nurse's time to focus on tasks that require their specialized skills and knowledge. Providing nail care and teaching foot care involve direct patient care and education, which should be performed by licensed nursing staff. Determining aspiration risk requires critical thinking and clinical judgment, making it a responsibility of the nurse.
3. A client asks a nurse about their Snellen eye test results. The client's visual acuity is 20/30. Which of the following responses should the nurse make?
- A. “Your eyes see at 20 feet what visually unimpaired eyes see at 30 feet.”
- B. “Your right eye can see the chart clearly at 20 feet, and your left eye can see the chart clearly at 30 feet.”
- C. “Your eyes see at 30 feet what visually unimpaired eyes see at 20 feet.”
- D. “Your left eye can see the chart clearly at 20 feet, and your right eye can see the chart clearly at 30 feet.”
Correct answer: A
Rationale: The correct answer is A: 'Your eyes see at 20 feet what visually unimpaired eyes see at 30 feet.' In the Snellen eye test, a visual acuity of 20/30 means that the client sees at 20 feet what a person with normal vision sees at 30 feet. This indicates that the client's vision is slightly worse than average. Choice B is incorrect as it incorrectly describes the visual acuity of each eye individually, rather than the combined visual acuity. Choice C is incorrect as it misinterprets the meaning of the Snellen eye test results by reversing the values. Choice D is incorrect as it inaccurately describes the visual acuity of the client's eyes, attributing different visual acuities to each eye instead of a combined measurement as indicated by 20/30.
4. Which of the following signs or symptoms is more common in children than adults following head trauma?
- A. nausea and vomiting
- B. altered mental status
- C. tachycardia and diaphoresis
- D. changes in pupillary reaction
Correct answer: A
Rationale: Nausea and vomiting are more common in children following head trauma due to their higher risk of increased intracranial pressure. Children have less space for swelling within the skull compared to adults, making them more prone to experiencing symptoms like nausea and vomiting. Altered mental status and changes in pupillary reaction can also occur in both children and adults following head trauma, but they are not specifically more common in children. Tachycardia and diaphoresis are generally signs of autonomic nervous system activation and may occur in both children and adults, but they are not typically more common in children compared to adults following head trauma.
5. A client who has an indwelling catheter reports a need to urinate. Which of the following actions should the nurse take?
- A. Check the catheter to see whether it is patent.
- B. Reassure the client that it is not possible for them to urinate.
- C. Re-catheterize the bladder with a larger-gauge catheter.
- D. Collect a urine specimen for analysis.
Correct answer: A
Rationale: When a client with an indwelling catheter reports a need to urinate, the nurse's initial action should be to check the catheter for patency. This is crucial to ensure that the catheter is not blocked, twisted, or kinked, which could lead to urinary retention. Reassuring the client without assessing the catheter could delay necessary interventions. Re-catheterizing the bladder with a larger-gauge catheter should not be the first step unless catheter patency is confirmed as an issue. Collecting a urine specimen for analysis is important but not the immediate priority when the client reports a need to urinate.
