Nursing Elites

1. The healthcare provider prescribes erythromycin (Ilosone) 300 mg PO QID. The medication label reads, 'Ilosone 100mg/5mL.' How many mL should the nurse administer at each dose?

• A. 15 mL
• B. 10 mL
• C. 20 mL
• D. 5 mL

Correct answer: A

Rationale: To determine the volume of medication needed for a 300 mg dose of Ilosone (100mg/5mL), we set up a proportion: 100 mg is to 5 mL as 300 mg is to x mL. Cross-multiplying, we get x = (300*5)/100 = 15 mL. Therefore, the nurse should administer 15 mL at each dose. Choice B (10 mL) is incorrect as it does not reflect the correct calculation based on the medication concentration. Choices C (20 mL) and D (5 mL) are also incorrect as they do not accurately calculate the volume required for the prescribed dose.

2. The client has chronic renal failure. What dietary modification is most important for this client?

• A. Increase protein intake
• B. Limit potassium-rich foods
• C. Increase sodium intake
• D. Encourage dairy products

Correct answer: B

Rationale: Limiting potassium-rich foods is crucial in chronic renal failure to prevent hyperkalemia, which can lead to cardiac complications. Excessive protein intake can increase the workload on the kidneys and may result in the accumulation of uremic toxins. Increasing sodium intake is generally discouraged in chronic renal failure due to its association with hypertension and fluid retention. Encouraging dairy products may not be suitable for all clients with chronic renal failure, as they are a significant source of phosphorus, which needs to be limited in renal failure to prevent mineral imbalances.

3. A client with asthma is prescribed a corticosteroid inhaler. What instruction should the nurse give about the inhaler?

• A. Use it only during asthma attacks
• B. Rinse the mouth after each use to prevent oral thrush
• C. It will provide immediate relief during an asthma attack
• D. Increase the dose if breathing does not improve

Correct answer: B

Rationale: The correct instruction for a client using a corticosteroid inhaler is to rinse the mouth after each use to prevent the development of oral thrush, a common side effect of these inhalers. Choice A is incorrect as corticosteroid inhalers are often used regularly as a maintenance treatment, not just during asthma attacks. Choice C is incorrect because corticosteroid inhalers provide long-term control of asthma symptoms, not immediate relief during an attack. Choice D is incorrect and potentially dangerous advice as increasing the dose without medical guidance can lead to adverse effects.

4. A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which laboratory finding is most indicative of this condition?

• A. Serum glucose of 180 mg/dL
• B. Blood pH of 7.30
• C. Positive urine ketones
• D. Serum bicarbonate of 25 mEq/L

Correct answer: C

Rationale: The correct answer is C: Positive urine ketones. In diabetic ketoacidosis (DKA), the body breaks down fat for energy due to a lack of insulin, leading to ketone production. Positive urine ketones are a hallmark laboratory finding in DKA as they directly reflect the presence of ketosis. Choice A, serum glucose of 180 mg/dL, may be elevated in DKA, but it is not specific to this condition. Choice B, blood pH of 7.30, often shows acidosis in DKA, but urine ketones are more specific to the presence of ketosis. Choice D, serum bicarbonate of 25 mEq/L, would typically be low in DKA due to acidosis rather than elevated.

5. What is the most important aspect of colostomy care to teach the client?

• A. Change the colostomy bag only when necessary
• B. Eat a low-residue diet
• C. Assess the stoma for color and swelling
• D. Irrigate the colostomy only if advised by a healthcare provider

Correct answer: C

Rationale: The most important aspect of colostomy care to teach the client is to assess the stoma for color and swelling. This is crucial as it ensures early detection of complications such as ischemia or infection. Changing the colostomy bag only when necessary is more appropriate than doing it daily, as it prevents unnecessary changes that may irritate the skin. While eating a low-residue diet is beneficial, it is not the most crucial aspect to teach. Irrigating the colostomy should only be done if advised by a healthcare provider, as it is not a routine procedure for all clients with a colostomy.
