Nursing Elites

1. The nurse is caring for a client with chronic heart failure who is receiving furosemide (Lasix). Which laboratory value requires immediate intervention?

• A. Serum potassium of 3.0 mEq/L
• B. Serum sodium of 135 mEq/L
• C. Serum creatinine of 1.8 mg/dL
• D. Blood glucose of 200 mg/dL

Correct answer: A

Rationale: A serum potassium level of 3.0 mEq/L is most concerning in a client receiving furosemide as it indicates hypokalemia, which requires immediate intervention. Hypokalemia can lead to serious cardiac arrhythmias, which can be life-threatening. Serum sodium of 135 mEq/L and serum creatinine of 1.8 mg/dL are within normal ranges and do not require immediate intervention in this case. Blood glucose of 200 mg/dL is elevated but does not pose an immediate threat to the client's life in the context of heart failure and furosemide therapy.

2. The nurse is assisting the mother of a child with phenylketonuria (PKU) to select foods that are in keeping with the child's dietary restrictions. Which foods are contraindicated for this child?

• A. Wheat products
• B. Foods sweetened with aspartame
• C. High-fat foods
• D. High-calorie foods

Correct answer: B

Rationale: The correct answer is B: Foods sweetened with aspartame. Aspartame should not be consumed by a child with PKU because it is converted to phenylalanine in the body, which can be harmful to individuals with PKU. Choice A (Wheat products) is not specifically contraindicated for PKU. Choice C (High-fat foods) and Choice D (High-calorie foods) are not typically restricted in PKU diets unless they contain high levels of phenylalanine.

3. The nurse is assessing a female client's blood pressure because she reported feeling dizzy. The blood pressure cuff is inflated to 140 mm Hg and as soon as the cuff is deflated a Korotkoff sound is heard. Which intervention should the nurse implement next?

• A. Wait 1 minute and palpate the systolic pressure before auscultating again.
• B. Increase the inflation pressure by 20 mm Hg and measure again.
• C. Switch to a larger cuff and repeat the measurement.
• D. Document the finding as normal.

Correct answer: A

Rationale: If a Korotkoff sound is heard immediately upon deflation, it may indicate an inaccurate reading. Waiting and palpating the systolic pressure can help confirm the accuracy of the measurement. Choice A is the correct intervention because it allows the nurse to ensure the accuracy of the blood pressure reading. Choice B is incorrect as increasing the inflation pressure is not necessary in this situation. Choice C is also incorrect as switching to a larger cuff is not warranted based on the information provided. Choice D is incorrect because documenting the finding as normal without further verification could lead to inaccurate information.

4. A female client who is admitted to the mental health unit for opiate dependency is receiving clonidine 0.1 mg PO for withdrawal symptoms. The client begins to complain of feeling nervous and tells the nurse that her bones are itching. Which finding should the nurse identify as a contraindication for administering the medication?

• A. Blood pressure 90/76 mm Hg.
• B. Heart rate of 85 bpm.
• C. Respiratory rate of 20 breaths/minute.
• D. Temperature of 99°F (37.2°C).

Correct answer: A

Rationale: Clonidine can lower blood pressure, so a BP of 90/76 mm Hg may indicate that it is unsafe to administer another dose. In this situation, the low blood pressure reading indicates that the client is already experiencing hypotension, which is a common side effect of clonidine. Administering more clonidine could further lower the blood pressure, leading to potential complications. The heart rate, respiratory rate, and temperature are within normal limits and do not serve as contraindications for administering clonidine in this scenario.

5. A nurse is preparing to administer a dose of digoxin (Lanoxin) to a client with heart failure. Which assessment finding requires immediate intervention?

• A. Apical pulse of 58 beats per minute
• B. Blood pressure of 110/70 mmHg
• C. Presence of a new murmur
• D. Respiratory rate of 18 breaths per minute

Correct answer: A

Rationale: An apical pulse of 58 beats per minute is concerning when administering digoxin because digoxin can further lower the heart rate, leading to bradycardia or heart block. Immediate intervention is required to prevent potential complications. A blood pressure of 110/70 mmHg is within normal range and does not require immediate intervention in this context. The presence of a new murmur may indicate valvular issues but does not directly relate to the administration of digoxin. A respiratory rate of 18 breaths per minute is also within normal limits and is not a priority concern when administering digoxin.
