Nursing Elites

1. The nurse is caring for a newly admitted patient who has severe gastroenteritis. The patient’s electrolytes reveal a serum sodium level of 140 mEq/L and a serum potassium level of 3.5 mEq/L. The nurse receives an order for intravenous 5% dextrose and normal saline with 20 mEq/L potassium chloride to infuse at 125 mL per hour. Which action is necessary prior to administering this fluid?

• A. Evaluate the patient’s urine output.
• B. Contact the provider to order arterial blood gases.
• C. Request an order for an initial potassium bolus.
• D. Suggest a diet low in sodium and potassium.

Correct answer: A

Rationale: Prior to administering IV fluids containing potassium, it is crucial to evaluate the patient's urine output. If the urine output is less than 25 mL/hr or 600 mL/day, there is a risk of potassium accumulation. Patients with low urine output should not receive IV potassium to prevent potential complications. Contacting the provider for arterial blood gases is unnecessary in this scenario as it does not directly relate to the administration of IV fluids with potassium. Administering potassium as a bolus is not recommended due to potential adverse effects. While dietary considerations are important, suggesting a low-sodium and low-potassium diet is not the immediate action required before administering IV fluids with potassium chloride.

2. The nurse is preparing to administer the first dose of hydrochlorothiazide (HydroDIURIL) 50 mg to a patient who has a blood pressure of 160/95 mm Hg. The nurse notes that the patient had a urine output of 200 mL in the past 12 hours. The nurse will perform which action?

• A. Administer the medication as ordered.
• B. Encourage the patient to drink more fluids.
• C. Hold the medication and request an order for serum BUN and creatinine.
• D. Request an order for serum electrolytes and administer the medication.

Correct answer: C

Rationale: The correct action is to hold the medication and request an order for serum BUN and creatinine. Thiazide diuretics, such as hydrochlorothiazide, are contraindicated in renal failure. In this case, the patient has oliguria, which is a reduced urine output, indicating potential renal insufficiency. Before administering the diuretic, it is crucial to evaluate the patient's renal function through serum BUN and creatinine levels. Encouraging the patient to drink more fluids (Choice B) may not address the underlying issue of renal function. Administering the medication as ordered (Choice A) without assessing renal function can be harmful. Requesting serum electrolytes and administering the medication (Choice D) overlooks the need for a specific evaluation of renal function in this scenario.

3. The client with diabetes mellitus should be cautioned by the nurse taking a sulfonylurea that alcoholic beverages should be avoided while taking these drugs because they can cause which of the following?

• A. Hypokalemia.
• B. Hyperkalemia.
• C. Hypocalcemia.
• D. Disulfiram (Antabuse)-like symptoms.

Correct answer: D

Rationale: The correct answer is D: Disulfiram (Antabuse)-like symptoms. When a client with diabetes mellitus taking a sulfonylurea consumes alcohol, it can lead to disulfiram-like symptoms, such as nausea, flushing, and palpitations. Choice A, hypokalemia, is incorrect because sulfonylureas do not typically lead to low potassium levels. Choice B, hyperkalemia, is incorrect as sulfonylureas are not associated with high potassium levels. Choice C, hypocalcemia, is also incorrect because sulfonylureas are not known to cause low calcium levels.

4. While assisting a client with a closed chest tube drainage system to move from bed to a chair, the chest tube gets caught on the chair leg and becomes dislodged from the insertion site. What is the immediate priority for the nurse?

• A. Contacting the physician
• B. Reinserting the chest tube
• C. Transferring the client back to bed
• D. Covering the insertion site with a sterile occlusive dressing

Correct answer: D

Rationale: The immediate priority for the nurse when a chest tube becomes dislodged from the insertion site is to cover the site with a sterile occlusive dressing. This action helps prevent air from entering the pleural space, which could lead to a pneumothorax. The nurse should then perform a respiratory assessment to monitor the client's breathing, assist the client back into bed to a position of comfort, and notify the physician. Reinserting the chest tube is a task for the physician, not the nurse, as it requires specific training and expertise.

5. A client with chronic renal failure is prescribed a low-protein diet. The nurse should explain to the client that the purpose of this diet is to:

• A. Prevent fluid overload.
• B. Reduce the workload on the kidneys.
• C. Prevent dehydration.
• D. Maintain electrolyte balance.

Correct answer: B

Rationale: The correct answer is B: 'Reduce the workload on the kidneys.' A low-protein diet is prescribed for clients with chronic renal failure to decrease the production of urea and other nitrogenous wastes, which can accumulate in the body when the kidneys are not functioning properly. This reduction in protein intake helps to lessen the burden on the kidneys, as they may have difficulty in filtering and excreting waste products. Choice A is incorrect because fluid overload is more related to restrictions in fluid intake rather than protein intake. Choice C is incorrect as a low-protein diet does not directly prevent dehydration. Choice D is incorrect because while electrolyte balance is essential in renal failure, the primary purpose of a low-protein diet is to reduce the workload on the kidneys by limiting the production of waste products.
