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 kidney disease (CKD) is scheduled for a renal biopsy. Which laboratory value should the nurse review before the procedure?

• A. Serum potassium
• B. Serum creatinine
• C. Hemoglobin
• D. White blood cell count

Correct answer: B

Rationale: Before a renal biopsy, the nurse should review the serum creatinine level. Serum creatinine is a key indicator of kidney function. In clients with chronic kidney disease (CKD), monitoring creatinine levels is crucial as elevated levels may indicate worsening kidney function, which could impact the safety and outcome of the biopsy. Hemoglobin (choice C) is important for assessing oxygen-carrying capacity but is not directly related to the kidney biopsy procedure. Serum potassium (choice A) is important to monitor in CKD but is not specifically crucial before a renal biopsy. White blood cell count (choice D) is more relevant for assessing infection or inflammation, which is not the primary concern before a renal biopsy.

3. In caring for a client with a PCA infusion of morphine sulfate through the right cephalic vein, the nurse assesses that the client is lethargic with a blood pressure of 90/60, pulse rate of 118 beats per minute, and respiratory rate of 8 breaths per minute. What assessment should the nurse perform next?

• A. Note the appearance and patency of the client's peripheral IV site.
• B. Palpate the volume of the client's right radial pulse.
• C. Auscultate the client's breath sounds bilaterally.
• D. Observe the amount and dose of morphine in the PCA pump syringe.

Correct answer: D

Rationale: In this scenario, the nurse is dealing with a lethargic client with concerning vital signs after a PCA infusion of morphine sulfate. The next assessment the nurse should perform is to observe the amount and dose of morphine in the PCA pump syringe. This is crucial to evaluate for possible overdose, as the client's symptoms could be indicative of opioid toxicity. Checking the morphine amount and dose will help the nurse adjust the treatment accordingly. Choices A, B, and C do not directly address the potential cause of the client's lethargy and abnormal vital signs related to the morphine infusion.

4. A client with type 2 diabetes is admitted with hyperglycemic hyperosmolar syndrome (HHS). Which intervention should the nurse implement first?

• A. Administer intravenous fluids.
• B. Monitor the client's urine output.
• C. Obtain a blood glucose level.
• D. Administer 50% dextrose IV push.

Correct answer: D

Rationale: The correct answer is to administer 50% dextrose IV push first. In hyperglycemic hyperosmolar syndrome, the main goal is to rapidly reduce blood glucose levels to prevent further complications. Administering dextrose intravenously can help reverse the effects of high blood glucose levels quickly. Administering intravenous fluids, monitoring urine output, and obtaining a blood glucose level are important interventions but are not the first priority in treating HHS. Administering 50% dextrose IV push takes precedence as it directly addresses the elevated blood glucose levels.

5. The nurse is caring for a client with acute respiratory distress syndrome (ARDS) who is receiving mechanical ventilation. Which assessment finding requires immediate intervention?

• A. Oxygen saturation of 90%
• B. Respiratory rate of 28 breaths per minute
• C. Tidal volume of 300 ml
• D. Blood pressure of 110/70 mmHg

Correct answer: C

Rationale: The correct answer is C. A tidal volume of 300 ml is concerning in a client with ARDS on mechanical ventilation because it indicates hypoventilation, which can lead to inadequate gas exchange and worsening respiratory status. This finding requires immediate intervention to optimize ventilation and oxygenation. Options A, B, and D are not as critical in this scenario. An oxygen saturation of 90% may be acceptable depending on the client's baseline condition and the target range set by the healthcare provider. A respiratory rate of 28 breaths per minute is slightly elevated but may not be immediately alarming. A blood pressure of 110/70 mmHg is within normal limits and does not require urgent intervention.
