1. Using Nägele's rule, what is the estimated date of delivery for a pregnant client who reports that the first day of her last menstrual period was August 2, 2006?
- A. April 25, 2007.
- B. May 9, 2007.
- C. May 29, 2007.
- D. June 2, 2007.
Correct answer: B
Rationale: Nägele's rule is used to estimate the date of delivery. It involves adding 7 days to the first day of the last menstrual period (August 2), which gives August 9. Then, subtracting 3 months from August 9, we arrive at May 9 of the following year as the estimated date of delivery. This makes choice B, 'May 9, 2007,' the correct answer. Choices A, C, and D are incorrect as they do not follow the correct calculation based on Nägele's rule.
2. The nurse is caring for a client undergoing the placement of a central venous catheter line. Which of the following would require the nurse's immediate attention?
- A. Pallor
- B. Increased temperature
- C. Dyspnea
- D. Involuntary muscle spasms
Correct answer: C
Rationale: Dyspnea indicates a potential complication such as pneumothorax or incorrect catheter placement, requiring immediate attention. Pallor may indicate anemia but is not as urgent as dyspnea in this context. Increased temperature could be a sign of infection but is not as critical as respiratory distress. Involuntary muscle spasms are not directly related to central venous catheter placement and are of lower priority compared to respiratory issues.
3. A client with chronic kidney disease has a potassium level of 6.2 mEq/L. Which intervention should the nurse implement?
- A. Encourage the client to eat foods rich in potassium
- B. Administer a potassium-sparing diuretic
- C. Administer a potassium-binding medication
- D. Hold all medications containing potassium
Correct answer: C
Rationale: A potassium level of 6.2 mEq/L indicates hyperkalemia, which is dangerous and requires immediate treatment. Administering a potassium-binding medication will help lower potassium levels and prevent life-threatening complications.
4. The RN on the evening shift receives a report that a client is scheduled for electroconvulsive treatment (ECT) in the morning. Which intervention should the RN implement the evening before the scheduled ECT?
- A. Hold all bedtime medications.
- B. Keep the client NPO after midnight.
- C. Implement elopement precautions.
- D. Give the client an enema at bedtime.
Correct answer: B
Rationale: Keeping the client NPO after midnight is the appropriate intervention before ECT to prevent complications during the procedure. Withholding food and fluids reduces the risk of aspiration and helps ensure the safety of the client. Option A (Hold all bedtime medications) is incorrect because medications may need to be given as prescribed unless specified otherwise by the healthcare provider. Option C (Implement elopement precautions) is unrelated to preparing a client for ECT and focuses on preventing a client from leaving the treatment area. Option D (Give the client an enema at bedtime) is unnecessary and not a standard pre-ECT preparation, making it an incorrect choice.
5. The nurse is caring for a patient who is receiving an intravenous antibiotic. The nurse notes that the provider has ordered serum drug peak and trough levels. The nurse understands that these tests are necessary for which type of drugs?
- A. Drugs with a broad spectrum
- B. Drugs with a narrow spectrum
- C. Drugs with a broad therapeutic index
- D. Drugs with a narrow therapeutic index
Correct answer: D
Rationale: Medications with a narrow therapeutic index have a limited range between the therapeutic dose and a toxic dose. It is important to monitor these medications closely by evaluating regular serum peak and trough levels. Drugs with a narrow spectrum (Choice B) are antibiotics that target only a limited group of bacteria, not related to the need for peak and trough monitoring. Drugs with a broad spectrum (Choice A) cover a wide range of bacteria, but this characteristic does not determine the need for peak and trough monitoring. Drugs with a broad therapeutic index (Choice C) have a wide safety margin between therapeutic and toxic doses, so they typically do not require peak and trough level monitoring.
