Nursing Elites

1. Which medication should the nurse withhold if the client's serum potassium level is 6.2 mEq/L?

• A. Losartan
• B. Spironolactone
• C. Metoprolol
• D. Furosemide

Correct answer: B

Rationale: The correct answer is B: Spironolactone. Spironolactone is a potassium-sparing diuretic that can lead to hyperkalemia. With potassium levels already elevated at 6.2 mEq/L, withholding Spironolactone is essential to prevent further increase in potassium levels, which could result in dangerous cardiac arrhythmias. Losartan (Choice A) is an angiotensin receptor blocker and does not directly affect potassium levels. Metoprolol (Choice C) is a beta-blocker and also does not impact potassium levels significantly. Furosemide (Choice D) is a loop diuretic that can actually lower potassium levels, so it would not be the medication to withhold in this case.

2. A client with myasthenia gravis (MG) is receiving immunosuppressive therapy. Recent lab tests show decreased serum magnesium. What nursing action is most important?

• A. Observe rhythm on telemetry monitor.
• B. Check for visual difficulties.
• C. Assess for hip and hand joint pain.
• D. Note the most recent hemoglobin level.

Correct answer: A

Rationale: Magnesium plays a crucial role in maintaining normal cardiac rhythms, particularly in patients with cardiac conditions. Abnormal levels can lead to arrhythmias, which is why continuous monitoring of the heart's electrical activity is important. Magnesium's effect on neuromuscular and cardiac function makes it essential to monitor its levels, and any discrepancies can impact treatment decisions. Checking for visual difficulties (choice B) may be important in MG but is not the priority in the context of decreased serum magnesium. Assessing for hip and hand joint pain (choice C) is not directly related to the issue of decreased serum magnesium. Noting the most recent hemoglobin level (choice D) is not the priority in this situation compared to monitoring the cardiac rhythm due to low magnesium levels.

3. A 5-week-old infant with hypertrophic pyloric stenosis has developed projectile vomiting over the last two weeks. Which intervention should the nurse plan to implement?

• A. Instruct the mother to give sugar water only.
• B. Offer the infant oral rehydration every 2 hours.
• C. Provide Pedialyte feedings via nasogastric tube.
• D. Maintain intravenous fluid therapy.

Correct answer: D

Rationale: The correct intervention for a 5-week-old infant with hypertrophic pyloric stenosis presenting with projectile vomiting is to maintain intravenous fluid therapy. This is essential to maintain hydration before surgery. Instructing the mother to give sugar water only (Choice A) is inadequate and does not address the need for proper hydration. Offering oral rehydration every 2 hours (Choice B) may not be effective in cases of severe vomiting and could lead to further fluid loss. Providing Pedialyte feedings via nasogastric tube (Choice C) is an option, but in severe cases, intravenous fluid therapy is more effective in ensuring hydration and electrolyte balance.

4. A client with type 2 diabetes mellitus arrives at the clinic reporting episodes of weakness and palpitations. Which finding should the nurse identify may indicate an emerging situation?

• A. History of hypertension
• B. Fingertips feel numb
• C. Reduced deep tendon reflexes
• D. Elevated fasting blood glucose level

Correct answer: B

Rationale: Numb fingertips may suggest neuropathy, a common complication of diabetes that may indicate a worsening condition. Episodes of weakness and palpitations, combined with neuropathy symptoms, could also suggest hypoglycemia or poor glycemic control, requiring further investigation. The other choices are less likely to be directly related to the client's current symptoms. While a history of hypertension is a common comorbidity in clients with diabetes, it may not directly explain the reported weakness and palpitations. Reduced deep tendon reflexes are more indicative of certain neurological conditions rather than acute emerging situations related to the client's current symptoms. An elevated fasting blood glucose level is expected in a client with type 2 diabetes and may not be the primary indicator of an emerging situation in this context.

5. A client with Type 2 diabetes is admitted with frequent hyperglycemic episodes and glycosylated hemoglobin (A1C) of 10%. What actions should the nurse include in the client's plan of care?

• A. Mixing glargine with aspart insulin to manage glucose levels.
• B. Teaching foot care to prevent injuries.
• C. Coordinating carbohydrate-controlled meals and subcutaneous injections.
• D. Reviewing site rotation for insulin injections.

Correct answer: C

Rationale: In managing a client with Type 2 diabetes experiencing frequent hyperglycemic episodes and with a high A1C level, it is crucial to coordinate carbohydrate-controlled meals and subcutaneous injections. This approach helps regulate blood glucose levels effectively. Mixing glargine with aspart insulin (Choice A) is not a recommended practice as these insulins have different onset and peak times. Teaching foot care (Choice B) is important in diabetes management but is not the priority in this scenario. Reviewing site rotation for insulin injections (Choice D) is important to prevent lipodystrophy but is not the immediate action needed to address the client's hyperglycemia and high A1C level.
