Nursing Elites

1. The nurse is caring for a client with congestive heart failure. On assessment, the nurse notes that the client is dyspneic and that crackles are audible on auscultation. The nurse suspects excess fluid volume. What additional signs would the nurse expect to note in this client if excess fluid volume is present?

• A. Weight loss
• B. Flat neck and hand veins
• C. An increase in blood pressure
• D. A decreased central venous pressure (CVP)

Correct answer: C

Rationale: An increase in blood pressure is a common sign of fluid volume excess in clients with congestive heart failure due to the increased amount of fluid in the vascular system. Weight loss (Choice A) is not typically associated with fluid volume excess. Flat neck and hand veins (Choice B) are signs of fluid volume deficit, not excess. A decreased central venous pressure (CVP) (Choice D) is not expected in a client with fluid volume excess.

2. The client is NPO and is receiving total parenteral nutrition (TPN) via a subclavian line. Which precautions should the nurse implement? Select one that does not apply.

• A. Place the solution on an IV pump at the prescribed rate.
• B. Monitor blood glucose every twelve (12) hours.
• C. Weigh the client weekly, first thing in the morning.
• D. Change the IV tubing every three (3) days.

Correct answer: D

Rationale: Precautions for clients receiving TPN include placing the solution on an IV pump to control the rate, monitoring blood glucose levels to detect hyperglycemia, and monitoring intake and output to assess fluid balance. Changing the IV tubing every three days is not a standard precaution for clients receiving TPN via a subclavian line.

3. A nurse is preparing a plan of care for a client with DM who has hyperglycemia. The priority nursing diagnosis would be:

• A. High risk for deficient fluid volume
• B. Deficient knowledge: disease process and treatment
• C. Imbalanced nutrition: less than body requirements
• D. Disabled family coping: compromised

Correct answer: A

Rationale: The priority nursing diagnosis for a client with diabetes mellitus (DM) experiencing hyperglycemia would be 'High risk for deficient fluid volume.' Hyperglycemia can lead to osmotic diuresis, causing significant fluid loss and an increased risk of deficient fluid volume. This nursing diagnosis addresses the immediate physiological concern related to fluid balance.\n\nChoice B, 'Deficient knowledge: disease process and treatment,' focuses on the client's understanding of DM, which is important but not the priority when the client is at risk of fluid volume deficit.\n\nChoice C, 'Imbalanced nutrition: less than body requirements,' pertains to inadequate intake of nutrients, which is not the priority concern when fluid volume deficit poses a more immediate threat.\n\nChoice D, 'Disabled family coping: compromised,' addresses a psychosocial aspect and is not the priority over the critical physiological issue of fluid volume deficit in a client with hyperglycemia.

4. A client with a diagnosis of diabetic ketoacidosis (DKA) is being treated in the ER. Which finding would a nurse expect to note as confirming this diagnosis?

• A. Elevated blood glucose level and a low plasma bicarbonate
• B. Decreased urine output
• C. Increased respirations and an increase in pH
• D. Comatose state

Correct answer: A

Rationale: The correct answer is A: Elevated blood glucose level and a low plasma bicarbonate. Diabetic ketoacidosis (DKA) is characterized by hyperglycemia, ketosis, and metabolic acidosis, reflected by a low plasma bicarbonate. Elevated blood glucose levels are a hallmark of DKA due to the body's inability to use glucose properly. Choices B, C, and D are incorrect. Decreased urine output is not a specific finding associated with DKA. Increased respirations and an increase in pH are not typical in DKA; in fact, respiratory compensation for the metabolic acidosis in DKA leads to Kussmaul breathing (deep, rapid breathing). A comatose state may occur in severe cases of DKA but is not a confirming finding for the diagnosis.

5. A healthcare provider caring for a client with severe malnutrition reviews the laboratory results and notes a magnesium level of 1.0 mg/dL. Which electrocardiographic change would the healthcare provider expect to note based on the magnesium level?

• A. Prominent U waves
• B. Prolonged PR interval
• C. Depressed ST segment
• D. Widened QRS complexes

Correct answer: C

Rationale: A magnesium level of 1.0 mg/dL can cause a depressed ST segment on the ECG. Magnesium deficiency commonly leads to ST segment depression on an electrocardiogram. Prominent U waves are associated with hypokalemia, prolonged PR interval is seen in conditions like first-degree heart block, and widened QRS complexes are typically related to conditions affecting the conduction system of the heart, such as bundle branch blocks.
