Nursing Elites

1. A client with a history of chronic renal failure is admitted with generalized edema. Which laboratory value should the LPN/LVN monitor to assess the client's fluid balance?

• A. Serum potassium
• B. Serum calcium
• C. Serum albumin
• D. Serum sodium

Correct answer: C

Rationale: The correct answer is C, Serum albumin. In clients with chronic renal failure and generalized edema, monitoring serum albumin levels is crucial as it is a key indicator of fluid balance. Low serum albumin levels can contribute to edema formation due to decreased oncotic pressure, indicating fluid imbalance. Serum potassium (Choice A) is more related to kidney function and electrolyte balance in renal failure patients. Serum calcium (Choice B) is important for bone health but is not directly related to fluid balance. Serum sodium (Choice D) is more indicative of hydration status and electrolyte balance but may not directly reflect fluid balance in the context of chronic renal failure and edema.

2. A client has a prescription for 5 units of regular insulin and 10 units of NPH insulin to mix together and administer subcutaneously. Determine the correct order of steps for this procedure.

• A. Inject 5 units of air into the bottle of regular insulin
• B. Withdraw the correct dose of NPH insulin from the bottle
• C. Inject 10 units of air into the bottle of NPH insulin
• D. Withdraw the correct dose of regular insulin from the bottle

Correct answer: B

Rationale: The correct order of steps for this procedure is to first inject air into the NPH insulin bottle to prevent vacuum formation. After injecting air into the NPH insulin, the next step is to withdraw the correct dose of regular insulin from its bottle. This sequence ensures that the regular insulin is drawn after the NPH insulin, preventing contamination and ensuring accurate dosing. Therefore, choice B is correct. Choices A, C, and D are incorrect because air should be injected into the NPH insulin first, not the regular insulin, and the doses should be withdrawn in the appropriate order to maintain the integrity and potency of each insulin type.

3. A client with rheumatoid arthritis is prescribed prednisone. What information should the LPN/LVN include when teaching the client about this medication?

• A. Take the medication with food to minimize gastrointestinal side effects.
• B. Avoid exposure to sunlight while taking this medication.
• C. Do not discontinue the medication abruptly.
• D. Increase fluid intake while taking this medication.

Correct answer: C

Rationale: The correct answer is C: 'Do not discontinue the medication abruptly.' It is crucial for clients prescribed prednisone to not stop the medication suddenly to prevent adrenal insufficiency, as this medication suppresses the body's natural production of cortisol. Choice A is incorrect because prednisone should be taken with food to minimize gastrointestinal side effects, not necessarily to prevent stomach upset. Choice B is incorrect as there is no specific need to avoid sunlight while taking prednisone. Choice D is not directly related to prednisone use; while adequate fluid intake is generally beneficial, it is not a specific instruction for prednisone administration.

4. A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which statement by the client indicates a need for further teaching?

• A. I will avoid foods high in vitamin K.
• B. I will take my medication at the same time every day.
• C. I will use a soft toothbrush to prevent gum bleeding.
• D. I can take aspirin if I have a headache.

Correct answer: D

Rationale: The correct answer is 'D: I can take aspirin if I have a headache.' This statement indicates a need for further teaching because aspirin can increase the risk of bleeding in clients taking warfarin. Clients on warfarin therapy should avoid taking aspirin or any other medications that can increase the risk of bleeding without consulting their healthcare provider. Choices A, B, and C are correct statements that demonstrate understanding of warfarin therapy and its potential side effects. Avoiding foods high in vitamin K helps maintain the effectiveness of warfarin, taking medication at the same time every day ensures consistent therapeutic levels, and using a soft toothbrush helps prevent gum bleeding, which can be a side effect of warfarin therapy.

5. Which serum blood finding in diabetic ketoacidosis alerts the nurse that immediate action is required?

• A. pH below 7.3
• B. Potassium of 5.0
• C. HCT of 60
• D. PaO2 of 79%

Correct answer: C

Rationale: A hematocrit (HCT) of 60 indicates severe dehydration, a critical condition in diabetic ketoacidosis that requires immediate intervention. Severe dehydration can lead to hypovolemic shock and organ failure. While a low pH below 7.3 is indicative of acidosis, it may not require immediate action compared to severe dehydration. A potassium level of 5.0 is within the normal range and not a critical finding in this scenario. PaO2 of 79% reflects oxygenation status, which is important but not the most critical finding requiring immediate action in diabetic ketoacidosis.
