Nursing Elites

1. Which of the following diuretics inhibits sodium reabsorption in the kidneys while sparing K+ and hydrogen ions?

• A. Spironolactone
• B. Furosemide
• C. Hydrochlorothiazide
• D. Bumetanide

Correct answer: A

Rationale: Spironolactone is the correct answer as it is classified as a potassium-sparing diuretic. It works by inhibiting sodium reabsorption in the kidneys while promoting the retention of potassium and hydrogen ions. This mechanism of action helps in reducing fluid retention without causing excessive loss of potassium, which is a common side effect of other diuretics. Furosemide (choice B), Hydrochlorothiazide (choice C), and Bumetanide (choice D) are not correct as they are not potassium-sparing diuretics. Furosemide and Bumetanide are loop diuretics that inhibit sodium, potassium, and chloride reabsorption in the loop of Henle. Hydrochlorothiazide is a thiazide diuretic that inhibits sodium and chloride reabsorption in the distal convoluted tubule, leading to potassium loss.

2. A client has a prescription for Phenytoin. Which of the following instructions should the nurse include?

• A. Take this medication at bedtime.
• B. Increase your intake of calcium-rich foods.
• C. Brush and floss your teeth regularly.
• D. Avoid eating foods high in potassium.

Correct answer: C

Rationale: The correct answer is C: 'Brush and floss your teeth regularly.' Phenytoin can cause gingival hyperplasia, a condition that leads to overgrowth of gum tissue. Good oral hygiene practices such as regular brushing and flossing can help prevent or minimize this side effect. In contrast, choices A, B, and D are not directly related to managing the side effects of Phenytoin. Taking the medication at bedtime (choice A) is not a specific instruction related to oral hygiene. Increasing calcium-rich foods intake (choice B) may be beneficial for bone health but is not directly related to preventing gingival hyperplasia. Avoiding foods high in potassium (choice D) is not a necessary instruction for a client taking Phenytoin.

3. When admitting a client and completing a preassessment before administering medications, which of the following data should the nurse include? (Select all that apply.)

• A. Use of herbal teas
• B. Daily fluid intake
• C. Current health status
• D. Previous surgical history

Correct answer: A

Rationale: The correct answer is A, 'Use of herbal teas.' The nurse should inquire about the client's use of herbal teas because they often contain caffeine, which can impact medication biotransformation. This information is crucial to ensure the safe and effective administration of medications and to prevent potential drug interactions. Choice B, 'Daily fluid intake,' while important for overall assessment, is not directly related to medication administration. Choice C, 'Current health status,' is essential but not specific to medication administration preassessment. Choice D, 'Previous surgical history,' although relevant for a client's medical history, is not directly linked to medication administration preassessment.

4. A client with chronic renal disease is receiving therapy with epoetin alfa. Which of the following laboratory results should the nurse review for an indication of a therapeutic effect of the medication?

• A. The leukocyte count
• B. The platelet count
• C. The hematocrit (Hct)
• D. The erythrocyte sedimentation rate (ESR)

Correct answer: C

Rationale: The correct answer is C: The hematocrit (Hct). Monitoring the hematocrit is essential to assess the therapeutic effect of epoetin alfa because this medication stimulates red blood cell production in clients with chronic renal disease. The leukocyte count (choice A) and platelet count (choice B) are not directly affected by epoetin alfa therapy. The erythrocyte sedimentation rate (ESR) (choice D) is a non-specific marker of inflammation and is not used to monitor the therapeutic effect of epoetin alfa.

5. A client is receiving vancomycin. Which of the following laboratory results should be monitored to evaluate the therapeutic effect of this medication?

• A. BUN
• B. Creatinine
• C. Hemoglobin
• D. White blood cell count

Correct answer: B

Rationale: Corrected Rationale: Creatinine levels should be monitored to evaluate vancomycin's effect on kidney function. Vancomycin can be nephrotoxic, so monitoring creatinine levels helps assess renal function and ensure that the medication is not causing harm to the kidneys. Monitoring BUN (choice A) is important for assessing kidney function but is not as specific as monitoring creatinine levels. Hemoglobin (choice C) and white blood cell count (choice D) are not directly related to evaluating the therapeutic effect of vancomycin.
