A nurse is caring for a client who has acute kidney injury and a potassium level of 6.5 mEq/L. Which of the following ECG changes should the nurse expect?
- A. Flattened T waves
- B. Peaked T waves
- C. Prolonged PR interval
- D. ST segment depression
Correct Answer: B
Rationale: The correct answer is B: Peaked T waves. In hyperkalemia (high potassium level), the myocardium becomes more excitable, leading to changes in the ECG. Peaked T waves are a classic sign of hyperkalemia, indicating early stages of cardiac involvement. Flattened T waves (choice A) are associated with hypokalemia. Prolonged PR interval (choice C) and ST segment depression (choice D) are not typically seen in hyperkalemia.

A home health nurse is assisting a client with planning care for a family member who has Alzheimers disease. Which of the following instructions should the nurse include?
- A. Review the daily schedule with the client every morning.
- B. Limit the clients fluid intake to prevent accidents.
- C. Encourage the client to engage in complex tasks.
- D. Restrict the clients social interactions to reduce confusion.
Correct Answer: A
Rationale: The correct answer is A: Review the daily schedule with the client every morning. This instruction is important for individuals with Alzheimer's disease as it helps provide structure and routine, which can help reduce confusion and anxiety. By reviewing the daily schedule, the client can be prepared for the day's activities, promoting a sense of familiarity and independence.
Option B is incorrect because limiting fluid intake can lead to dehydration and other health issues. Option C is incorrect as individuals with Alzheimer's disease may struggle with complex tasks and may become frustrated. Option D is incorrect because social interactions are important for mental stimulation and emotional well-being, restricting them can lead to increased confusion and isolation.
A nurse is monitoring a client who has a traumatic brain injury. Which of the following findings should the nurse identify as a manifestation of Cushings triad?
- A. Increase in blood pressure from 130/80 mm Hg to 180/100 mm Hg
- B. Decrease in heart rate to 120 bpm
- C. Rapid shallow respirations
- D. Hypotension
Correct Answer: A
Rationale: The correct answer is A: Increase in blood pressure from 130/80 mm Hg to 180/100 mm Hg. Cushing's triad is a classic sign of increased intracranial pressure (ICP), seen in traumatic brain injury. It consists of hypertension (elevated blood pressure), bradycardia (not tachycardia), and irregular respirations (not rapid shallow respirations). The increase in blood pressure is due to the body's attempt to maintain cerebral perfusion in response to the increased ICP. The other choices are incorrect because they do not align with the classic presentation of Cushing's triad in traumatic brain injury.
A nurse is monitoring a client following a lumbar laminectomy. The client has a drain and indwelling urinary catheter. The nurse should identify which of the following findings as an indication of a complication of the surgery?
- A. Red-tinged drainage on the dressing
- B. Cloudy urine in the catheter
- C. Clear drainage on the dressings
- D. Mild back pain at the surgical site
Correct Answer: C
Rationale: The correct answer is C: Clear drainage on the dressings. Clear drainage may indicate a cerebrospinal fluid leak, which is a serious complication following a lumbar laminectomy. Cerebrospinal fluid is a clear fluid that surrounds the brain and spinal cord, and its leakage can lead to infection and other complications. Red-tinged drainage (choice A) may be expected initially due to surgical trauma. Cloudy urine in the catheter (choice B) is more likely related to urinary tract infection. Mild back pain at the surgical site (choice D) is common after this surgery and does not necessarily indicate a complication.
A nurse is planning care for a client who has a lump in their right breast. Which of the following findings increases the clients risk of developing breast cancer?
- A. Daily caffeine consumption
- B. A history of seasonal allergies
- C. Oral contraceptives were taken for the last 6 years
- D. Routine use of multivitamins
Correct Answer: C
Rationale: The correct answer is C: Oral contraceptives were taken for the last 6 years. Long-term use of oral contraceptives has been associated with a slightly increased risk of developing breast cancer. Estrogen and progesterone in oral contraceptives can stimulate the growth of breast tissue, potentially leading to cancer over time. Daily caffeine consumption (choice A) and a history of seasonal allergies (choice B) do not have a direct correlation with an increased risk of breast cancer. Routine use of multivitamins (choice D) is generally not linked to an increased risk of breast cancer.
A nurse is preparing to administer propranolol to several clients. For which of the following clients should the nurse clarify the prescription with the provider before administration?
- A. A client who has a history of asthma
- B. A client who has hypertension
- C. A client who has a history of migraines
- D. A client who has stable angina
Correct Answer: A
Rationale: The correct answer is A: A client who has a history of asthma. Propranolol is a non-selective beta-blocker that can potentially exacerbate bronchospasm in patients with asthma due to its mechanism of action. Therefore, the nurse should clarify the prescription with the provider before administering it to a client with asthma to avoid potential adverse effects. Choices B, C, and D are not contraindications for propranolol use, so there is no need to clarify the prescription for clients with hypertension, migraines, or stable angina.
