Nursing Elites

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 client with chronic obstructive pulmonary disease (COPD) is experiencing shortness of breath and has a prescription for oxygen therapy. What is the maximum amount of oxygen the nurse should administer without a healthcare provider's order?

• A. 2 liters per minute
• B. 4 liters per minute
• C. 6 liters per minute
• D. 8 liters per minute

Correct answer: B

Rationale: The correct answer is 4 liters per minute. Without a healthcare provider's order, the nurse should administer a maximum of 4 liters per minute of oxygen to prevent carbon dioxide retention in COPD clients. Higher flow rates can lead to oxygen toxicity and worsen the client's condition. Choices A, C, and D exceed the safe limit for oxygen administration without a healthcare provider's order.

3. The nurse reviews the laboratory findings of a client with an open fracture of the tibia. The white blood cell (WBC) count and erythrocyte sedimentation rate (ESR) are elevated. Before reporting this information to the healthcare provider, what assessment should the nurse obtain?

• A. Appearance of wound
• B. Pain level
• C. Presence of fever
• D. Mobility status

Correct answer: A

Rationale: The correct answer is A: Appearance of wound. Elevated WBC and ESR levels suggest a possible infection in the client with an open fracture. Assessing the wound's appearance is crucial to evaluate for signs of infection, such as redness, warmth, swelling, or drainage. By assessing the wound first, the nurse can provide important information to the healthcare provider regarding the potential infection, which may require immediate intervention. Choices B, C, and D are important assessments in caring for a client with an open fracture; however, in this scenario, the priority is to assess the wound for signs of infection due to the elevated WBC and ESR levels.

4. A client is being treated with an aminoglycoside antibiotic for a serious gram-negative infection. What nursing action should be included in the plan of care to prevent nephrotoxicity?

• A. Monitor serum creatinine levels daily.
• B. Administer the antibiotic over a longer period of time.
• C. Encourage increased fluid intake.
• D. Restrict dietary protein intake.

Correct answer: A

Rationale: Monitoring serum creatinine levels daily is the essential nursing action to prevent nephrotoxicity from aminoglycoside antibiotics. Aminoglycosides can cause kidney damage, so monitoring serum creatinine levels helps in detecting early signs of nephrotoxicity. Administering the antibiotic over a longer period of time (choice B) does not directly prevent nephrotoxicity. Encouraging increased fluid intake (choice C) is a general good practice but not specifically aimed at preventing nephrotoxicity. Restricting dietary protein intake (choice D) is not a direct preventive measure against aminoglycoside-induced nephrotoxicity.

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.
