A client with a diagnosis of hyperkalemia is receiving sodium polystyrene sulfonate (Kayexalate). Which laboratory value should the nurse monitor to evaluate the effectiveness of this medication?
- A. Serum sodium level.
- B. Serum potassium level.
- C. Serum calcium level.
- D. Serum glucose level.
Correct Answer: B
Rationale: The correct answer is B: Serum potassium level. Sodium polystyrene sulfonate (Kayexalate) is used to treat hyperkalemia by exchanging sodium ions for potassium ions in the intestines, leading to potassium removal from the body. Monitoring the serum potassium level allows the nurse to assess the effectiveness of this medication in lowering the elevated potassium levels. Serum sodium (A), calcium (C), and glucose (D) levels are not directly impacted by the action of sodium polystyrene sulfonate.

A client is admitted with a fever of unknown origin. To assess fever patterns, which intervention should the nurse implement?
- A. Document the client's temperature fluctuations
- B. Assess for flushed, warm skin consistently
- C. Measure temperature at regular intervals
- D. Use different sites for temperature measurement
Correct Answer: C
Rationale: To assess fever patterns accurately, the nurse should measure the client's temperature at regular intervals. This approach helps in identifying the pattern of fever spikes and fluctuations, which can provide valuable information for diagnostic and treatment purposes. Assessing for flushed, warm skin or documenting circadian rhythms may not directly reveal the fever pattern, while varying temperature measurement sites could lead to inconsistent readings. Therefore, measuring temperature at regular intervals is the most appropriate intervention to identify fever patterns in this scenario.
The client reports still being unable to sleep a week after learning progressive muscle relaxation techniques. Which action should the nurse take first?
- A. Instruct the client to add regular exercise to the daily routine.
- B. Determine if the client has been keeping a sleep diary.
- C. Encourage the client to continue the routine until sleep is achieved.
- D. Ask the client to describe the routine currently followed.
Correct Answer: D
Rationale: The nurse should first assess the client's adherence to the original instructions. By asking the client to describe the routine, the nurse can evaluate if the technique is being correctly implemented before considering further interventions. This choice is correct as it focuses on assessing the client's current practice. Option A is incorrect as adding regular exercise may not address the issue with the relaxation technique. Option B is incorrect as determining if the client has been keeping a sleep diary does not directly address the efficacy of the relaxation technique. Option C is incorrect as blindly encouraging the client to continue may not be the best approach without understanding how the technique is being practiced.
One week after being told that she has terminal cancer with a life expectancy of 3 weeks, a female client tells the nurse, 'I think I will plan a big party for all my friends.' How should the nurse respond?
- A. You may not have enough energy before long to hold a big party.
- B. Do you mean to say that you want to plan your funeral and wake?
- C. Planning a party and thinking about all your friends sounds like fun.
- D. You should be thinking about spending your last days with your family.
Correct Answer: C
Rationale: Setting goals that bring pleasure is appropriate and should be encouraged by the nurse. Choice A is discouraging and focuses on limitations. Choice B jumps to a conclusion and is not in line with the client's statement. Choice D dictates what the client should be doing, which is not respectful of the client's autonomy. Therefore, the most appropriate response is C, as it acknowledges the client's wishes and provides positive reinforcement without perpetuating denial.
The client is weak from inactivity due to a 2-week hospitalization. In planning care for the client, which range of motion (ROM) exercises should the nurse include?
- A. Passive ROM exercises to all joints on all extremities four times a day.
- B. Active ROM exercises to both arms and legs two or three times a day.
- C. Active ROM exercises with weights twice a day, 20 repetitions each.
- D. Passive ROM exercises to the point of resistance and slightly beyond.
Correct Answer: B
Rationale: Active ROM exercises are preferred over passive ROM to restore strength. Performing them on both arms and legs two or three times a day is effective in promoting muscle strength and mobility without the need for external assistance. Choice A is incorrect as passive ROM exercises may not help in restoring strength. Choice C is not recommended as using weights may be too strenuous for a weak client. Choice D is incorrect as passive ROM exercises to the point of resistance and slightly beyond may cause discomfort or injury to the weak client.
The nurse is instructing a client with high cholesterol about diet and life style modification. What comment from the client indicates that the teaching has been effective?
- A. If I exercise at least two times weekly for one hour, I will lower my cholesterol.
- B. I need to avoid eating proteins, including red meat.
- C. I will limit my intake of beef to 4 ounces per week.
- D. My blood level of low density lipoproteins needs to increase.
Correct Answer: C
Rationale: Limiting saturated fat from animal food sources to no more than 4 ounces per week is an important diet modification for lowering cholesterol. To be effective in reducing cholesterol, the client should exercise 30 minutes per day, or at least 4 to 6 times per week. Red meat and all proteins do not need to be eliminated to lower cholesterol, but should be restricted to lean cuts of red meat and smaller portions. The low density lipoproteins need to decrease rather than increase.
