1. The nurse discovers that an elderly client with no history of cardiac or renal disease has an elevated serum magnesium level. To further investigate the cause of this electrolyte imbalance, what information is most important for the nurse to obtain from the client's medical history?
- A. Frequency of laxative use for chronic constipation
- B. Dietary intake of magnesium-rich foods
- C. Use of magnesium-containing supplements
- D. History of alcohol use
Correct answer: A
Rationale: The correct answer is A. Frequent use of magnesium-containing laxatives can lead to hypermagnesemia, particularly in elderly clients. Option B, dietary intake of magnesium-rich foods, may contribute to elevated serum magnesium levels but is less likely the cause in this scenario. Option C, the use of magnesium-containing supplements, can also contribute to hypermagnesemia but is not as common in elderly clients without a history of using such supplements. Option D, history of alcohol use, is less relevant to the development of elevated serum magnesium levels compared to laxative use for chronic constipation.
2. A male client with cancer who has lost 10 pounds during the last months tells the nurse that beef, chicken, and eggs, which used to be his favorite foods, now taste 'bitter'. He complains that he simply has no appetite. What action should the nurse implement?
- A. Suggest the use of alternative sources of protein such as dairy products and nuts.
- B. Encourage the client to eat smaller, more frequent meals.
- C. Offer nutritional supplements between meals.
- D. Discuss the possibility of appetite stimulants with the healthcare provider.
Correct answer: A
Rationale: Offering alternative protein sources like dairy products and nuts can help maintain nutrition when the client finds certain foods unpalatable, as in this case where beef, chicken, and eggs taste 'bitter'. Encouraging smaller, more frequent meals may not address the issue of unpalatable foods. Offering nutritional supplements between meals may not specifically address the problem of protein intake. Discussing appetite stimulants should be considered after exploring less invasive options first.
3. An unlicensed assistive personnel (UAP) assigned to obtain client vital signs reports to the charge nurse that a client has a weak pulse with a rate of 44 beats/minute. What action should the charge nurse implement?
- A. Instruct the UAP to count the client's apical pulse rate for sixty seconds.
- B. Determine if the UAP also measured the client's capillary refill time.
- C. Assign a practical nurse (LPN) to determine if an apical-radial pulse deficit is present.
- D. Notify the healthcare provider of the abnormal pulse rate and pulse volume.
Correct answer: C
Rationale: The correct action for the charge nurse to implement in this situation is to assign a practical nurse (LPN) to determine if an apical-radial pulse deficit is present. This helps to confirm the accuracy of the reported weak pulse. In this scenario, it is crucial to involve a licensed nurse to further assess the situation and provide a more comprehensive evaluation. Inaccurate pulse readings can lead to inappropriate interventions or unnecessary alarm. Instructing the UAP to count the apical pulse may not address the accuracy issue. Checking capillary refill time is not directly related to confirming the weak pulse rate. Notifying the healthcare provider immediately may be premature without confirming the accuracy of the pulse reading first.
4. A client with a history of chronic heart failure is admitted with shortness of breath and crackles in the lungs. Which laboratory value should be closely monitored?
- A. Serum creatinine of 2.0 mg/dL
- B. Serum sodium of 135 mEq/L
- C. Serum potassium of 5.5 mEq/L
- D. Blood glucose of 150 mg/dL
Correct answer: C
Rationale: A serum potassium level of 5.5 mEq/L should be closely monitored in a client with chronic heart failure as it may indicate hyperkalemia, requiring intervention. Hyperkalemia can lead to life-threatening cardiac arrhythmias in patients with heart failure. Serum creatinine (Choice A) is important to monitor for kidney function but is not the priority in this case. Serum sodium (Choice B) and blood glucose (Choice D) levels are not typically the primary focus when assessing a client with heart failure presenting with respiratory symptoms and crackles in the lungs.
5. The nurse is caring for a client with chronic kidney disease (CKD). Which laboratory value should be reported to the healthcare provider immediately?
- A. Serum creatinine of 2.0 mg/dl
- B. Hemoglobin of 10 g/dl
- C. Potassium of 6.5 mEq/L
- D. Blood glucose of 150 mg/dl
Correct answer: C
Rationale: The correct answer is C. A potassium level of 6.5 mEq/L is dangerously high, a condition known as hyperkalemia, and requires immediate intervention to prevent cardiac complications. Hyperkalemia can lead to life-threatening arrhythmias, making it crucial to notify the healthcare provider promptly. Choices A, B, and D do not indicate immediate life-threatening conditions. Elevated serum creatinine levels are expected in CKD, a hemoglobin level of 10 g/dl is within a reasonable range, and a blood glucose level of 150 mg/dl is not acutely concerning in this context.
