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 nurse is assessing the status of a client with diabetes mellitus. The nurse concludes that the client is exhibiting adequate diabetic control if the serum level of glycosylated hemoglobin A1C (HbA1C) is less than:

• A. 7%
• B. 9%
• C. 10%
• D. 15%

Correct answer: A

Rationale: The correct answer is A: 7%. Glycosylated hemoglobin A1C (HbA1C) level of 7.0% or less is considered indicative of adequate diabetic control. This level reflects good long-term blood sugar management. Choices B, C, and D are incorrect because an HbA1C level above 7% indicates poor diabetic control and an increased risk of complications associated with diabetes, such as cardiovascular disease, neuropathy, and retinopathy.

3. The client with chronic renal failure is being taught about fluid restrictions by the nurse. Which statement by the client indicates a need for further teaching?

• A. I can drink as much water as I want, as long as I limit my salt intake.
• B. I should limit my fluid intake to prevent fluid overload.
• C. I can skip dialysis sessions if I feel tired.
• D. I can eat whatever I want, as long as I take my medications.

Correct answer: C

Rationale: Choice C is the correct answer because clients with chronic renal failure should not skip dialysis sessions. Skipping dialysis can lead to serious complications and worsen the client's condition. It is crucial for clients to understand the importance of adhering to their dialysis schedule for optimal management of chronic renal failure. Choices A, B, and D are incorrect because they demonstrate understanding of fluid restrictions, the need to limit fluid intake to prevent overload, and the importance of medication compliance, respectively. These statements show appropriate knowledge and do not indicate a need for further teaching.

4. A client with chronic renal failure is receiving sodium polystyrene sulfonate (Kayexalate). The nurse should monitor the client for which of the following?

• A. Hyponatremia.
• B. Hypokalemia.
• C. Hyperkalemia.
• D. Hypocalcemia.

Correct answer: C

Rationale: Correct Answer: The correct answer is C, 'Hyperkalemia.' Sodium polystyrene sulfonate (Kayexalate) is a medication used to treat high potassium levels (hyperkalemia) by exchanging sodium ions for potassium ions in the intestines, leading to potassium removal from the body. Therefore, the nurse should monitor the client for changes in potassium levels to assess the effectiveness of the medication and prevent potential complications related to hyperkalemia. Choice A, 'Hyponatremia,' is incorrect as Kayexalate does not primarily affect sodium levels. Choice B, 'Hypokalemia,' is incorrect as Kayexalate is used to treat high potassium levels, not low. Choice D, 'Hypocalcemia,' is incorrect as Kayexalate does not directly impact calcium levels.

5. After teaching a client with bacterial cystitis who is prescribed phenazopyridine (Pyridium), the nurse assesses the client’s understanding. Which statement made by the client indicates a correct understanding of the teaching?

• A. I will not take this drug with food or milk.
• B. If I suspect pregnancy, I will discontinue the drug.
• C. An orange color in my urine should not alarm me.
• D. I will consume two glasses of cranberry juice daily.

Correct answer: C

Rationale: The correct answer is C. Phenazopyridine commonly discolors urine to a deep reddish orange, which can be mistaken for blood. It is important for the client to understand that this color change is an expected side effect and should not be a cause for alarm. Additionally, the urine can stain clothing. There are no dietary restrictions or precautions related to food or milk intake while taking phenazopyridine. Stopping the medication if suspecting pregnancy is not necessary as phenazopyridine is safe to use during pregnancy. Drinking cranberry juice is not directly related to the use of phenazopyridine and is not a specific instruction given for managing bacterial cystitis.
