Nursing Elites

1. A nurse is planning care for a client who has chronic kidney disease. Which finding indicates the need for hemodialysis?

• A. BUN 14 mg/dL
• B. Serum potassium 4.2 mEq/L
• C. Serum creatinine 5 mg/dL
• D. Serum calcium 9 mg/dL

Correct answer: C

Rationale: The correct answer is C. A serum creatinine level of 5 mg/dL is significantly elevated and indicates the need for hemodialysis to help filter waste products from the blood. Elevated creatinine levels suggest impaired kidney function and the inability to effectively filter waste from the body. Choices A, B, and D are within normal ranges and do not indicate the need for immediate hemodialysis in a client with chronic kidney disease.

2. A client with a new prescription for an albuterol metered-dose inhaler is being taught by a nurse. Which of the following instructions should the nurse include in the teaching?

• A. Inhale quickly when using the inhaler.
• B. Hold your breath for 10 seconds after inhaling the medication.
• C. Take a second puff of the inhaler immediately after the first.
• D. Exhale fully after using the inhaler.

Correct answer: B

Rationale: The correct instruction is to hold your breath for 10 seconds after inhaling the medication. This allows the medication to settle in the lungs and maximize its effectiveness. Choice A is incorrect as inhaling quickly may lead to improper medication delivery. Choice C is wrong because taking a second puff immediately after the first without waiting for the prescribed interval may cause an overdose. Choice D is also incorrect as exhaling fully after using the inhaler may result in the medication being exhaled rather than absorbed by the lungs.

3. A client has been prescribed vasopressin for the treatment of diabetes insipidus. What is the expected pharmacological action of this medication?

• A. To stimulate the pancreas to secrete insulin
• B. To slow the absorption of glucose in the intestine
• C. To increase reabsorption of water in the renal tubules
• D. To increase blood pressure

Correct answer: C

Rationale: The correct answer is C: To increase reabsorption of water in the renal tubules. Vasopressin mimics the action of antidiuretic hormone (ADH) by increasing the reabsorption of water in the renal tubules. This leads to decreased urine output, helping to manage symptoms of diabetes insipidus, which is characterized by excessive thirst and urination. Choices A, B, and D are incorrect. Vasopressin does not stimulate the pancreas to secrete insulin, slow the absorption of glucose in the intestine, or directly increase blood pressure.

4. A nurse is assessing a male adolescent client who has heart failure. Based on the client’s chart, which of the following actions should the nurse plan to take?

• A. Withhold spironolactone
• B. Administer ferrous sulfate
• C. Administer furosemide
• D. Withhold digoxin

Correct answer: C

Rationale: The correct answer is to administer furosemide. Furosemide is a diuretic commonly used in heart failure to manage fluid retention, helping alleviate symptoms like edema and shortness of breath. Withholding spironolactone, a potassium-sparing diuretic, could lead to electrolyte imbalances. Administering ferrous sulfate is used to treat iron deficiency anemia, not heart failure. Withholding digoxin, a medication used in heart failure to improve heart function, can worsen the client's condition.

5. A nurse is preparing to administer a pneumococcal vaccine. Which of the following should the nurse verify?

• A. Client's allergy to eggs
• B. Client's current medications
• C. Client's vaccination history
• D. Client's blood pressure

Correct answer: C

Rationale: The correct answer is C: Client's vaccination history. Before administering a pneumococcal vaccine, the nurse should verify the client's vaccination history to ensure they are due for the vaccine. Verifying the vaccination history helps prevent unnecessary vaccinations and ensures that the client receives the appropriate immunization at the right time. Choices A, B, and D are not directly related to the administration of the pneumococcal vaccine. Checking for allergies to eggs may be important for other vaccines, but it is not specifically relevant to pneumococcal vaccination. The client's current medications and blood pressure are important for general health assessment but are not directly related to verifying the need for a pneumococcal vaccine.
