Nursing Elites

1. In a client with congestive heart failure, the nurse would be correct in withholding a dose of digoxin without specific instruction from the healthcare provider if the client's

• A. serum digoxin level is 1.5 ng/mL.
• B. blood pressure is 104/68 mmHg.
• C. serum potassium level is 3 mEq/L.
• D. apical pulse is 68/min.

Correct answer: C

Rationale: The correct answer is C. Hypokalemia can precipitate digitalis toxicity in individuals on digoxin, increasing the risk of dangerous dysrhythmias. A serum potassium level of 3 mEq/L is below the normal range (3.5 to 5.5 mEq/L) and indicates hypokalemia, which can potentiate the effects of digoxin. Choices A, B, and D are not directly related to the potential for digitalis toxicity. Serum digoxin level of 1.5 ng/mL is within the therapeutic range, blood pressure of 104/68 mmHg is not a contraindication for administering digoxin, and an apical pulse of 68/min is within the normal range and not a reason to withhold digoxin.

2. A patient has begun taking spironolactone (Aldactone) in addition to a thiazide diuretic. With the addition of the spironolactone, the nurse will counsel this patient to

• A. not take a potassium supplement daily.
• B. recognize that abdominal cramping is a common side effect.
• C. report decreased urine output to the provider.
• D. take these medications in the morning.

Correct answer: C

Rationale: When combining a potassium-sparing diuretic like spironolactone with a thiazide diuretic, there is an increased risk of hyperkalemia, especially in patients with poor renal function. Therefore, the patient should be educated to report any decrease in urine output, which could indicate a potential issue with kidney function. Choice A is incorrect because taking additional potassium supplements can further increase the risk of hyperkalemia. Choice B is incorrect as abdominal cramping is not a common side effect of spironolactone. Choice D is incorrect because the timing of medication administration is not directly related to the addition of spironolactone and thiazide diuretic; there is no specific recommendation to take these medications only at bedtime.

3. A client with type 1 diabetes mellitus who jogs daily is being taught by a nurse about the preferred sites for insulin absorption. What is the most appropriate site for this client?

• A. Arms
• B. Legs
• C. Abdomen
• D. Iliac crest

Correct answer: C

Rationale: The abdomen is the most appropriate site for insulin absorption in a client who jogs. When a client is involved in physical activity like jogging, the abdomen is preferred as it provides more consistent absorption compared to the arms or legs, which can have altered absorption rates due to increased blood flow during exercise. The iliac crest is not a common site for insulin injections and may not provide optimal absorption rates compared to the abdomen.

4. The patient weighs 75 kg and is receiving IV fluids at a rate of 50 mL/hour, having consumed 100 mL orally in the past 24 hours. What action will the nurse take?

• A. Contact the provider to ask about increasing the IV rate to 90 mL/hour.
• B. Discuss with the provider the need to increase the IV rate to 150 mL/hour.
• C. Encourage the patient to drink more water so the IV can be discontinued.
• D. Instruct the patient to drink 250 mL of water every 8 hours.

Correct answer: A

Rationale: The recommended daily fluid intake for adults is 30 to 40 mL/kg/day. For a patient weighing 75 kg, the minimum intake should be 2250 mL/day. The patient is currently receiving 1200 mL IV and 100 mL orally, totaling 1300 mL. Increasing the IV rate to 90 mL/hour would provide a total of 2160 mL, which could meet the patient's needs if oral intake continues. Option B suggests increasing the IV rate to 150 mL/hour, resulting in an excessive fluid intake of 3600 mL/day, surpassing the recommended amount. Option C, encouraging increased fluid intake, is not recommended as the patient is already struggling with fluid intake. Option D, instructing the patient to drink 250 mL of water every 8 hours, would still fall short of the required fluid intake of 2250 mL/day.

5. A client is admitted with acute kidney injury (AKI) and a urine output of 2000 mL/day. What is the major concern of the nurse regarding this client’s care?

• A. Edema and pain
• B. Electrolyte and fluid imbalance
• C. Cardiac and respiratory status
• D. Mental health status

Correct answer: B

Rationale: The major concern for a client admitted with acute kidney injury (AKI) and a high urine output of 2000 mL/day is electrolyte and fluid imbalance. In AKI, there may be an inflammatory cause leading to proteins entering the glomerulus, resulting in fluid being held in the filtrate and causing polyuria. Electrolyte loss and fluid balance are critical to monitor and manage in AKI cases. Edema and pain are not typically associated with fluid loss. While changes in cardiac, respiratory, and mental health status can occur if electrolyte imbalance is not addressed, the primary focus should be on managing electrolyte and fluid balance to prevent further complications.
