Nursing Elites

1. A nurse is assigned to care for a group of clients. On reviewing the clients' medical records, the nurse determines that which client is at risk for deficient fluid volume?

• A. A client with a colostomy
• B. A client with congestive heart failure
• C. A client with decreased kidney function
• D. A client receiving frequent wound irrigations

Correct answer: A

Rationale: The correct answer is A. Clients with a colostomy are at risk for deficient fluid volume due to the loss of fluid through the colostomy. In colostomy, there can be increased fluid loss through the stoma, which may lead to dehydration and electrolyte imbalances. Choices B, C, and D do not directly relate to the risk for deficient fluid volume. Clients with congestive heart failure are more prone to fluid overload rather than deficient volume. Clients with decreased kidney function are at risk for fluid retention, not deficient volume. Clients receiving frequent wound irrigations may be at risk for infection, but this does not directly indicate deficient fluid volume.

2. A client with type 1 diabetes mellitus presents with nausea, vomiting, and abdominal pain. The nurse suspects diabetic ketoacidosis (DKA). Which of the following lab findings would confirm this diagnosis?

• A. Serum glucose of 180 mg/dL
• B. Serum bicarbonate of 22 mEq/L
• C. Blood pH of 7.25
• D. Urine specific gravity of 1.020

Correct answer: C

Rationale: A blood pH of 7.25 is a critical finding in diabetic ketoacidosis (DKA) as it indicates metabolic acidosis, which is a hallmark of this condition. In DKA, there is an accumulation of ketones in the blood, leading to increased acidity. The serum glucose level is typically elevated in DKA, often exceeding 250 mg/dL. A serum bicarbonate level less than 18 mEq/L is usually seen in DKA due to the metabolic acidosis. Urine specific gravity is not a specific indicator for DKA and may vary depending on the individual's hydration status. Therefore, the correct lab finding that confirms DKA in this scenario is a blood pH of 7.25.

3. A male client with a tentative diagnosis of hyperosmolar hyperglycemic nonketotic syndrome (HHNS) has a history of type 2 diabetes that is being controlled with an oral diabetic agent, tolazamide (Tolinase). Which of the following is the most important laboratory test for confirming this disorder?

• A. Serum potassium level
• B. Serum sodium level
• C. Arterial blood gas (ABG) values
• D. Serum osmolarity

Correct answer: D

Rationale: Serum osmolarity is the most important laboratory test for confirming hyperosmolar hyperglycemic nonketotic syndrome (HHNS). HHNS is characterized by severe hyperglycemia and dehydration without ketoacidosis. Elevated serum osmolarity indicates increased solute concentration in the blood, which is a hallmark of HHNS. Serum potassium level (Choice A) is important in conditions like diabetic ketoacidosis rather than HHNS. Serum sodium level (Choice B) may be affected in HHNS but is not the primary test for confirming the disorder. Arterial blood gas (ABG) values (Choice C) are more useful in assessing acid-base status, which is not the primary concern in HHNS.

4. Nurse Ronn is assessing a client with possible Cushing's syndrome. In a client with Cushing's syndrome, the nurse would expect to find:

• A. Hypotension.
• B. Thick, coarse skin.
• C. Deposits of adipose tissue in the trunk and dorsocervical area.
• D. Weight gain in arms and legs.

Correct answer: C

Rationale: In Cushing's syndrome, the characteristic features include central obesity with deposits of adipose tissue in the trunk and dorsocervical area, often referred to as a 'buffalo hump.' Hypotension (Choice A) is not typically associated with Cushing's syndrome; instead, hypertension is more common. Thick, coarse skin (Choice B) is seen in conditions like hypothyroidism, not specifically in Cushing's syndrome. Weight gain in the arms and legs (Choice D) is not a typical finding in Cushing's syndrome; rather, weight gain is more prominent in the central areas of the body.

5. A client with type 2 DM is being treated with metformin (Glucophage). The nurse should include which instruction when teaching the client about this medication?

• A. Take the medication with meals.
• B. Take the medication on an empty stomach.
• C. Take the medication before bedtime.
• D. Avoid taking the medication if you miss a meal.

Correct answer: A

Rationale: The correct instruction for a client taking metformin (Glucophage) is to take the medication with meals. This helps reduce gastrointestinal side effects and improves absorption. Choice B is incorrect because taking metformin on an empty stomach can increase the risk of side effects. Choice C is incorrect as there is no specific recommendation to take metformin before bedtime. Choice D is incorrect as missing a meal should not lead to avoiding the medication, but the client should take it with the next meal as prescribed.
