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 healthcare provider reviews the laboratory results of a client whose serum pH is 7.38. What does this value imply about the client's homeostasis?

• A. Alkalosis
• B. Acidosis
• C. Normal serum pH
• D. Incompatible with life

Correct answer: C

Rationale: A pH of 7.38 falls within the normal range (7.35-7.45), indicating that the client’s acid-base balance is adequately maintained. Choices A and B are incorrect as alkalosis and acidosis refer to abnormal pH levels. Choice D is incorrect as a pH of 7.38 within the normal range is compatible with life.

3. A client with foul-smelling drainage from an incision on the upper left arm is admitted with a suspected methicillin-resistant Staphylococcus aureus (MRSA). Which nursing interventions should the nurse include in the plan of care? (Select all that apply.)

• A. Send wound drainage for culture and sensitivity.
• B. Institute contact precautions for staff and visitors.
• C. Use standard precautions and wear a mask.
• D. Monitor the client's white blood cell count.

Correct answer: B

Rationale: When dealing with a client suspected of having MRSA, the nurse should implement contact precautions to prevent the spread of infection. This includes using gowns and gloves, along with following proper hand hygiene practices. Sending wound drainage for culture and sensitivity may be necessary for diagnostic purposes, but it is not directly related to preventing the spread of infection in this case. Using standard precautions and wearing a mask are not sufficient when dealing with MRSA; contact precautions are specifically required to prevent transmission. Monitoring the client's white blood cell count is important in assessing infection status but is not a primary intervention to prevent the spread of MRSA.

4. A 9-year-old is receiving vancomycin 400 mg IV every 6 hours for a methicillin-resistant (Beta-lactam-resistant) Staphylococci aureus (MRSA) infection. The medication is diluted in a 100 mL bag of saline with instructions to infuse over one and a half hours. How many mL/hour should the nurse program the infusion pump?

• A. 50
• B. 67
• C. 57
• D. 70

Correct answer: B

Rationale: To calculate the infusion rate for vancomycin, you need to divide the total volume by the total time of infusion. In this case, the total volume is 100 mL, and the total time is 1.5 hours. Therefore, 100 mL ÷ 1.5 hours = 67 mL/hour. This means the nurse should program the infusion pump to deliver vancomycin at a rate of 67 mL/hour. Choice A (50) is incorrect as it does not reflect the correct calculation. Choice C (57) is incorrect as it is not the accurate calculation based on the provided information. Choice D (70) is incorrect as it does not correspond to the correct infusion rate calculation.

5. A client is diagnosed with Angina Pectoris. Which factor in the client's history is likely related to the anginal pain?

• A. Smokes one pack of cigarettes daily
• B. Drinks two beers daily
• C. Works in a job that requires exposure to the sun
• D. Eats while lying in bed

Correct answer: A

Rationale: The correct answer is A: 'Smokes one pack of cigarettes daily.' Smoking is a major risk factor for angina and other cardiovascular diseases due to its impact on blood vessels. Choice B, 'Drinks two beers daily,' is not directly associated with angina pectoris. While excessive alcohol consumption can contribute to heart problems, it is not a primary risk factor for angina. Choice C, 'Works in a job that requires exposure to the sun,' is not typically related to angina pectoris. Sun exposure is more closely linked to skin-related conditions. Choice D, 'Eats while lying in bed,' is also not a common risk factor for angina. While certain eating habits can impact heart health, this specific behavior is not directly associated with angina pectoris.
