Nursing Elites

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

• A. The client taking diuretics
• B. The client with renal failure
• C. The client with an ileostomy
• D. The client who requires gastrointestinal suctioning

Correct answer: B

Rationale: The correct answer is B. Clients with renal failure are unable to excrete fluids effectively, leading to an increased risk of fluid volume excess. Option A, the client taking diuretics, would be at risk for fluid volume deficit due to increased urine output caused by the diuretics. Option C, the client with an ileostomy, is at risk for fluid volume deficit due to increased output from the ileostomy. Option D, the client who requires gastrointestinal suctioning, may be at risk for dehydration, but not specifically excess fluid volume.

2. A client with hyperthyroidism is prescribed radioactive iodine therapy. The nurse should monitor for which of the following potential side effects?

• A. Hypothyroidism
• B. Hyperthyroidism
• C. Hypercalcemia
• D. Hyperglycemia

Correct answer: A

Rationale: When a client with hyperthyroidism undergoes radioactive iodine therapy, the treatment aims to reduce thyroid hormone production by destroying thyroid tissue. As a result, there is a high likelihood of developing hypothyroidism as a side effect. Monitoring for hypothyroidism is crucial post-treatment. Choices B, C, and D are incorrect because the therapeutic goal is to address hyperthyroidism by inducing hypothyroidism through the treatment.

3. A client with type 2 diabetes mellitus is taking metformin. The nurse should monitor the client for which of the following potential side effects?

• A. Lactic acidosis
• B. Hypokalemia
• C. Hyperglycemia
• D. Weight gain

Correct answer: A

Rationale: The correct answer is A: Lactic acidosis. Metformin, a common medication for type 2 diabetes mellitus, can lead to lactic acidosis, particularly in individuals with renal impairment or other predisposing factors. Monitoring for signs and symptoms of lactic acidosis, such as muscle pain, weakness, trouble breathing, dizziness, and slow or irregular heartbeat, is crucial when a client is taking metformin. Choice B, hypokalemia, is not a common side effect of metformin. Choice C, hyperglycemia, is contrary to the intended effect of metformin, which is to lower blood glucose levels. Choice D, weight gain, is not typically associated with metformin use; in fact, metformin may even contribute to weight loss in some individuals.

4. 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.

5. A client with a nasogastric tube requires irrigation once every shift. The client's serum electrolyte results show a potassium level of 4.5 mEq/L and a sodium level of 132 mEq/L. Based on these findings, which solution should the nurse use for nasogastric tube irrigation?

• A. Tap water
• B. Sterile water
• C. Sodium chloride
• D. Normal saline

Correct answer: C

Rationale: The correct solution for nasogastric tube irrigation in this scenario is sodium chloride. The client's low sodium level of 132 mEq/L indicates the need to avoid further imbalance, making sodium chloride the most appropriate choice. Using tap water, which lacks electrolytes, or sterile water could potentially exacerbate the electrolyte imbalance. Normal saline, while similar to sodium chloride, may not be the best choice as it contains a higher concentration of sodium, which could further elevate the client's already borderline sodium level.
