Nursing Elites

1. What is the most important nursing intervention for a patient with increased intracranial pressure (ICP)?

• A. Elevate the head of the bed to 30 degrees.
• B. Administer diuretics to reduce fluid volume.
• C. Administer corticosteroids to reduce inflammation.
• D. Keep the patient in a supine position.

Correct answer: A

Rationale: Elevating the head of the bed to 30 degrees is crucial for a patient with increased intracranial pressure (ICP) because it helps promote venous drainage from the brain, thereby reducing ICP. Keeping the head of the bed elevated helps facilitate cerebral perfusion and can prevent a further increase in ICP. Administering diuretics (Choice B) may be considered in some cases to reduce fluid volume, but it is not the most critical intervention for immediate ICP management. Administering corticosteroids (Choice C) is not typically indicated for managing increased ICP unless there is a specific underlying condition requiring their use. Keeping the patient in a supine position (Choice D) can actually worsen ICP by impeding venous outflow from the brain, making it an incorrect choice for this scenario.

2. The nurse is caring for a patient who is receiving an intravenous antibiotic. The nurse notes that the provider has ordered serum drug peak and trough levels. The nurse understands that these tests are necessary for which type of drugs?

• A. Drugs with a broad spectrum
• B. Drugs with a narrow spectrum
• C. Drugs with a broad therapeutic index
• D. Drugs with a narrow therapeutic index

Correct answer: D

Rationale: Medications with a narrow therapeutic index have a limited range between the therapeutic dose and a toxic dose. It is important to monitor these medications closely by evaluating regular serum peak and trough levels. Drugs with a narrow spectrum (Choice B) are antibiotics that target only a limited group of bacteria, not related to the need for peak and trough monitoring. Drugs with a broad spectrum (Choice A) cover a wide range of bacteria, but this characteristic does not determine the need for peak and trough monitoring. Drugs with a broad therapeutic index (Choice C) have a wide safety margin between therapeutic and toxic doses, so they typically do not require peak and trough level monitoring.

3. Angiotensin-converting enzyme (ACE) inhibitors may be prescribed for the client with diabetes mellitus to reduce vascular changes and possibly prevent or delay the development of:

• A. Chronic obstructive pulmonary disease (COPD).
• B. Pancreatic cancer.
• C. Renal failure.
• D. Cerebrovascular accident.

Correct answer: C

Rationale: The correct answer is C: Renal failure. ACE inhibitors are commonly used in clients with diabetes mellitus to help reduce the progression of diabetic nephropathy by improving renal blood flow. This medication class can help prevent or delay the development of renal failure in these clients. Choices A, B, and D are incorrect because ACE inhibitors do not have a direct impact on preventing or delaying the development of chronic obstructive pulmonary disease, pancreatic cancer, or cerebrovascular accidents in clients with diabetes mellitus.

4. A client is placed on fluid restrictions because of chronic kidney disease (CKD). Which assessment finding would alert the nurse that the client’s fluid balance is stable at this time?

• A. Decreased calcium levels
• B. Increased phosphorus levels
• C. No adventitious sounds in the lungs
• D. Increased edema in the legs

Correct answer: C

Rationale: The absence of adventitious sounds upon auscultation of the lungs is a key indicator that the client's fluid balance is stable. Adventitious sounds, such as crackles or wheezes, are typically heard in conditions of fluid overload, indicating that the body is retaining excess fluid. Choices A and B, decreased calcium levels and increased phosphorus levels, are common laboratory findings associated with chronic kidney disease (CKD) and are not directly related to fluid balance. Increased edema in the legs is a sign of fluid imbalance, suggesting fluid retention in the tissues, which would not indicate stable fluid balance in a client with CKD on fluid restrictions.

5. A client with renal insufficiency and a low red blood cell count asks, 'Is my anemia related to the renal insufficiency?' How should the nurse respond?

• A. Red blood cells produce erythropoietin, which increases blood flow to the kidneys.
• B. Your anemia and renal insufficiency are related to inadequate vitamin D and a loss of bone density.
• C. Erythropoietin is usually released from the kidneys and stimulates red blood cell production in the bone marrow.
• D. Kidney insufficiency inhibits active transportation of red blood cells throughout the blood.

Correct answer: C

Rationale: The correct answer is C. Erythropoietin is produced in the kidney and is released in response to decreased oxygen tension in the renal blood supply. Erythropoietin stimulates red blood cell production in the bone marrow. Anemia in renal insufficiency is often due to decreased erythropoietin production. Anemia and renal insufficiency are not manifestations of vitamin D deficiency as stated in choice B. Choice A is incorrect as erythropoietin does not increase blood flow to the kidneys. Choice D is incorrect because kidney insufficiency does not inhibit active transportation of red blood cells throughout the blood; rather, it affects erythropoietin production and subsequent red blood cell formation.
