Nursing Elites

1. How can a nurse determine the efficacy of a child's mebendazole treatment for roundworm after 3 weeks?

• A. Liver function tests
• B. Stool for ova and parasites
• C. Colonoscopy or sigmoidoscopy
• D. Rectal swab for culture

Correct answer: B

Rationale: The correct answer is B: Stool for ova and parasites. To assess the efficacy of treatment for roundworm, the nurse would examine the stool for ova (eggs) and parasites. This test helps determine if the infection has been cleared. Choices A, C, and D are incorrect because liver function tests are not commonly used to monitor roundworm treatment efficacy, and colonoscopy/sigmoidoscopy as well as rectal swab for culture are not routine diagnostic tests for assessing the effectiveness of mebendazole treatment for roundworm.

2. A 43-year-old man has tested positive for systemic candidiasis, and the care team has decided on IV fluconazole as a first-line treatment. When administering this medication, the nurse should

• A. administer the drug with lactated Ringer's.
• B. infuse the drug no faster than 200 mg/h.
• C. avoid administering the drug through a peripheral IV.
• D. administer prophylactic heparin prior to the fluconazole.

Correct answer: C

Rationale: When administering IV fluconazole, the nurse should avoid administering the drug through a peripheral IV. Fluconazole is known to cause phlebitis and tissue irritation if infused through a peripheral IV line. It is recommended to administer fluconazole through a central venous catheter to reduce the risk of complications. Choices A, B, and D are incorrect as there is no specific recommendation to administer the drug with lactated Ringer's, infuse it at a particular rate, or administer prophylactic heparin prior to fluconazole in this scenario.

3. What occurs in a client with polycythemia?

• A. Deficient plasma in the blood
• B. Increased lymphatic fluid being produced
• C. Increased red blood cells being produced
• D. Deficient number of red blood cells

Correct answer: C

Rationale: The correct answer is C: Increased red blood cells being produced. Polycythemia is a condition characterized by an elevated number of red blood cells in the blood. This increased concentration of red blood cells can lead to blood thickening and potentially result in complications such as blood clots. Choices A, B, and D are incorrect because polycythemia does not involve deficient plasma, increased lymphatic fluid production, or a deficient number of red blood cells.

4. Which pathophysiologic process causes the decreased glomerular filtration rate in a patient with acute glomerulonephritis?

• A. Decreased renal-induced constriction of the renal arteries
• B. Immune complex deposition, increased capillary permeability, and cellular proliferation
• C. Necrosis of 70% or more of the nephrons secondary to increased kidney interstitial hydrostatic pressure
• D. Scar tissue formation throughout the proximal convoluted tubule secondary to toxin-induced collagen synthesis

Correct answer: B

Rationale: The correct answer is B: Immune complex deposition, increased capillary permeability, and cellular proliferation. In acute glomerulonephritis, immune complexes deposit in the glomerulus, leading to inflammation, increased capillary permeability, and cellular proliferation. These processes collectively reduce the glomerular filtration rate. Choices A, C, and D do not accurately describe the pathophysiologic process in acute glomerulonephritis. Decreased renal-induced constriction of the renal arteries, necrosis of nephrons due to increased kidney interstitial hydrostatic pressure, and scar tissue formation in the proximal convoluted tubule are not the primary mechanisms responsible for the decreased filtration rate in this condition.

5. A patient is starting on atorvastatin (Lipitor) for hyperlipidemia. What critical instruction should the nurse provide?

• A. Take the medication at night to reduce the risk of muscle pain and other side effects.
• B. Avoid consuming grapefruit juice while taking this medication.
• C. Take the medication in the morning with breakfast to improve absorption.
• D. Take the medication with a high-fat meal to increase its effectiveness.

Correct answer: A

Rationale: The correct answer is to take the medication at night to reduce the risk of muscle pain and other side effects. Atorvastatin, like other statins, is more effective when taken in the evening as the body produces more cholesterol at night. Taking it with a high-fat meal (choice D) is not recommended as it may reduce the drug's absorption. Grapefruit juice (choice B) should be avoided with atorvastatin as it can increase the risk of side effects. Taking the medication in the morning with breakfast (choice C) is not as effective as taking it at night.
