Nursing Elites

1. A client with a diagnosis of myocardial infarction (MI) is prescribed nitroglycerin. What is the primary action of this medication?

• A. Increases heart rate
• B. Lowers blood pressure
• C. Dilates coronary arteries
• D. Reduces myocardial oxygen demand

Correct answer: C

Rationale: The correct answer is C: Nitroglycerin dilates coronary arteries, improving blood flow to the heart muscle. This helps increase oxygen supply to the heart tissue. Option A, 'Increases heart rate,' is incorrect because nitroglycerin does not directly affect heart rate. Option B, 'Lowers blood pressure,' is also incorrect as while nitroglycerin can lower blood pressure, its primary action in the context of MI is related to coronary artery dilation. Option D, 'Reduces myocardial oxygen demand,' is not the primary action of nitroglycerin in the treatment of myocardial infarction; its main action is to increase oxygen supply by dilating coronary arteries.

2. The nurse plans to administer the rubella vaccine to a postpartum client whose titer is < 1:8 and who is breastfeeding. What information should the nurse provide this client?

• A. The client should bottle feed and pump her breast for 3 days following immunization
• B. The vaccine is given to produce maternal antibodies before lactation occurs
• C. The infant will receive immunization through the mother's breast milk
• D. The client should not get pregnant for 3 months after immunization

Correct answer: D

Rationale: Educating about the waiting period helps prevent possible rubella infection in a subsequent early pregnancy.

3. The client with diabetes is being taught about the importance of foot care. Which statement by the client indicates a need for further teaching?

• A. ''I will inspect my feet daily for any cuts or blisters.''
• B. ''I will soak my feet in warm water every day.''
• C. ''I will wear shoes that fit properly to avoid injury.''
• D. ''I will avoid walking barefoot to protect my feet.''

Correct answer: B

Rationale: Choice B is the correct answer because soaking feet daily can lead to skin breakdown, making it inappropriate for clients with diabetes. Inspecting feet daily for cuts or blisters (Choice A), wearing properly fitting shoes (Choice C), and avoiding walking barefoot (Choice D) are all appropriate measures to maintain foot health for clients with diabetes.

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. The nurse is assessing a client with congestive heart failure who is receiving furosemide (Lasix). Which laboratory value should the nurse monitor closely?

• A. Sodium level
• B. Potassium level
• C. Calcium level
• D. Chloride level

Correct answer: B

Rationale: The correct answer is B: Potassium level. Furosemide is a loop diuretic that can cause potassium loss, leading to hypokalemia. Monitoring the potassium level is crucial to prevent complications such as cardiac arrhythmias. Sodium level (choice A) is not typically affected by furosemide. Calcium level (choice C) and chloride level (choice D) are also not the primary focus of monitoring when a client is on furosemide for heart failure.
