Nursing Elites

1. The client with chronic renal failure is being taught about dietary restrictions by the nurse. Which of the following food items should the client avoid?

• A. Apples
• B. Bananas
• C. Chicken
• D. Rice

Correct answer: B

Rationale: The correct answer is B: Bananas. Bananas are high in potassium, which should be limited in clients with chronic renal failure to prevent hyperkalemia. Apples (choice A), chicken (choice C), and rice (choice D) are not typically restricted in clients with chronic renal failure. Apples and rice are lower in potassium, while chicken is a good source of lean protein, which is usually encouraged in these clients to meet their protein needs without excess potassium intake.

2. What is the correct procedure for performing an ophthalmoscopic examination on a client's right retina?

• A. Instruct the client to focus on a distant object behind the examiner and not move their eyes during the exam.
• B. Set the ophthalmoscope on the plus 2 to 3 lens and hold it in front of the examiner's right eye.
• C. From a distance of 12 to 15 inches and slightly to the side, shine the light into the client's pupil.
• D. For optimal visualization, keep the ophthalmoscope at least 3 inches from the client's eye.

Correct answer: C

Rationale: During an ophthalmoscopic examination, the client should focus on a distant object behind the examiner to dilate the pupil, and the examiner should stand at a distance of 12-15 inches away and slightly to the side. This angle allows for better visualization of the retina. Holding the ophthalmoscope firmly against the examiner's face and shining the light into the client's pupil helps examine the retina effectively. Choice A is incorrect because the client should look at a distant object, not the examiner's nose. Choice B is incorrect as the ophthalmoscope should be directed towards the client's eye, not the examiner's eye. Choice D is incorrect because keeping the ophthalmoscope at least 3 inches away may not provide an optimal view of the retina.

3. What is the most common side effect of diuretics such as furosemide (Lasix)?

• A. Hypokalemia.
• B. Hyperkalemia.
• C. Hypernatremia.
• D. Hyponatremia.

Correct answer: A

Rationale: The correct answer is 'Hypokalemia.' Diuretics like furosemide increase the excretion of potassium, leading to hypokalemia as a common side effect. Hyperkalemia (choice B) is the opposite condition characterized by high potassium levels, which is not typically associated with furosemide use. Hypernatremia (choice C) is increased sodium levels, while hyponatremia (choice D) is decreased sodium levels, neither of which are the most common side effects of furosemide. Therefore, choice A is the best answer.

4. The nurse is caring for a patient who is taking trimethoprim-sulfamethoxazole (TMP-SMX). The nurse learns that the patient takes an angiotensin-converting enzyme (ACE) inhibitor. To monitor for drug interactions, the nurse will request an order for which laboratory test(s)?

• A. A complete blood count
• B. BUN and creatinine
• C. Electrolytes
• D. Glucose

Correct answer: C

Rationale: The correct answer is 'C. Electrolytes.' When trimethoprim-sulfamethoxazole (TMP-SMX) is taken with an ACE inhibitor, there is an increased risk of hyperkalemia due to the combined effects on potassium levels. Monitoring electrolytes, specifically potassium, is essential to detect and manage this potential drug interaction. Choices A, B, and D are incorrect because while they are important tests in general patient care, they are not specifically indicated to monitor for the drug interaction between TMP-SMX and ACE inhibitors.

5. When a patient starts taking amoxicillin, which foods should the nurse instruct the patient to avoid?

• A. Green leafy vegetables
• B. Beef and other red meat
• C. Coffee, tea, and colas
• D. Acidic fruits and juices

Correct answer: D

Rationale: The correct answer is D: Acidic fruits and juices. Amoxicillin can be irritating to the stomach, so avoiding acidic fruits and juices is recommended to reduce stomach discomfort or potential interactions. Green leafy vegetables (Choice A), beef and other red meat (Choice B), and coffee, tea, and colas (Choice C) are not typically contraindicated with amoxicillin. It is important to focus on acidic foods and beverages to promote comfort and effectiveness of the medication.
