Nursing Elites

1. The healthcare provider assesses a client with cirrhosis and finds 4+ pitting edema of the feet and legs, and massive ascites. Which mechanism contributes to edema and ascites in clients with cirrhosis?

• A. Hyperaldosteronism causing increased sodium transport ion in renal tubules
• B. Decreased portacaval pressure with greater collateral circulation
• C. Decreased renin-angiotensin response related to increased renal blood flow
• D. Hypoalbuminemia that results in decreased colloidal oncotic pressure

Correct answer: D

Rationale: In clients with cirrhosis, hypoalbuminemia leads to decreased colloidal oncotic pressure. This reduction in oncotic pressure contributes to the development of edema in the feet and legs (pitting edema) and ascites in the abdomen. Hyperaldosteronism (choice A) would lead to sodium retention but is not the primary mechanism behind edema and ascites in cirrhosis. Decreased portacaval pressure with greater collateral circulation (choice B) is not directly related to the pathophysiology of edema and ascites in cirrhosis. Decreased renin-angiotensin response related to increased renal blood flow (choice C) does not play a significant role in the development of edema and ascites in cirrhosis compared to the impact of hypoalbuminemia on colloidal oncotic pressure.

2. The nurse is caring for a patient who has had severe vomiting. The patient’s serum sodium level is 130 mEq/L. The nurse will expect the patient’s provider to order which treatment?

• A. Diuretic therapy
• B. Intravenous hypertonic 5% saline
• C. Intravenous normal saline 0.9%
• D. Oral sodium supplements

Correct answer: C

Rationale: In this scenario, the patient has hyponatremia with a serum sodium level of 130 mEq/L. For a serum sodium level between 125 and 135 mEq/L, the appropriate treatment is intravenous normal saline 0.9%. Normal saline helps to increase the sodium content in the vascular fluid. Diuretic therapy would exacerbate sodium and fluid depletion, which is not suitable for a patient already dehydrated from severe vomiting. Intravenous hypertonic 5% saline is typically reserved for severe hyponatremia with a serum sodium level below 120 mEq/L. Oral sodium supplements are not feasible in this case as the patient is vomiting and may not be able to tolerate oral intake easily.

3. What is a key intervention for a patient with diabetic ketoacidosis (DKA)?

• A. Administering insulin
• B. Administering IV fluids
• C. Administering oral glucose
• D. Administering oral fluids

Correct answer: A

Rationale: Administering insulin is a crucial intervention for a patient with diabetic ketoacidosis (DKA) because it helps in managing hyperglycemia and ketosis by promoting the uptake of glucose by cells and inhibiting the production of ketones. IV fluids are necessary to correct dehydration and electrolyte imbalances commonly seen in DKA but are not the primary treatment for the condition. Administering oral glucose would exacerbate hyperglycemia in a patient with DKA, while administering oral fluids alone would not effectively address the underlying metabolic disturbances seen in DKA.

4. Laboratory findings indicate that a client's serum potassium level is 2.5 mEq/L. What action should the nurse take?

• A. Inform the healthcare provider of the need for potassium replacement.
• B. Prepare to administer a glucose-insulin-potassium replacement.
• C. Change the plan of care to include hourly urinary output measurement.
• D. Instruct the client to increase daily intake of potassium-rich foods.

Correct answer: A

Rationale: A serum potassium level of 2.5 mEq/L is critically low, indicating severe hypokalemia. The immediate action the nurse should take is to inform the healthcare provider of the need for potassium replacement. Option B, preparing to administer glucose-insulin-potassium replacement, is not the first-line intervention; it may be considered in specific situations but requires a healthcare provider's prescription. Option C, changing the plan of care to include hourly urinary output measurement, is not the priority when managing critically low potassium levels. Option D, instructing the client to increase daily intake of potassium-rich foods, is not appropriate in this acute situation where immediate intervention is needed to address the dangerously low potassium level.

5. A client is hospitalized with heart failure (HF). Which intervention should the nurse implement to improve ventilation and reduce venous return?

• A. Perform passive range of motion exercises
• B. Place the client in high Fowler's position
• C. Administer oxygen via nasal cannula
• D. Increase the client's activity level

Correct answer: B

Rationale: In clients with heart failure, placing them in high Fowler's position is beneficial as it helps reduce venous return and improve ventilation. This position aids in decreasing the workload on the heart by promoting better lung expansion and oxygenation. Passive range of motion exercises (Choice A) are not directly related to improving ventilation or reducing venous return. Administering oxygen via nasal cannula (Choice C) may help with oxygenation but does not directly address reducing venous return. Increasing the client's activity level (Choice D) may worsen heart failure symptoms by increasing the workload on the heart.
