A client with DM is scheduled to have surgery. The nurse should plan to:
- A. Give the client a regular diet as ordered.
- B. Hold the client's insulin on the morning of surgery.
- C. Monitor the client's blood glucose level closely during the perioperative period.
- D. Have the client stop taking insulin 48 hours before surgery.
Correct Answer: C
Rationale: The correct answer is to monitor the client's blood glucose level closely during the perioperative period. This is essential to ensure that the client's blood glucose levels remain within the target range and to prevent complications such as hypo- or hyperglycemia. Choices A, B, and D are incorrect because giving a regular diet as ordered, holding insulin on the morning of surgery, or stopping insulin 48 hours before surgery can lead to uncontrolled blood glucose levels, posing risks to the client's safety during the surgical procedure.

The nurse is caring for a client with syndrome of inappropriate antidiuretic hormone (SIADH). Which of the following clinical manifestations should the nurse expect?
- A. Hypernatremia
- B. Hypotension
- C. Decreased urine output
- D. Polyuria
Correct Answer: C
Rationale: The correct answer is C: 'Decreased urine output.' Syndrome of inappropriate antidiuretic hormone (SIADH) is characterized by excessive release of antidiuretic hormone, leading to water retention and decreased urine output. Therefore, the nurse should expect the client to have decreased urine output. Choices A, B, and D are incorrect. Hypernatremia (Choice A) is not typically associated with SIADH as it usually leads to dilutional hyponatremia. Hypotension (Choice B) is not a common clinical manifestation of SIADH. Polyuria (Choice D) is the opposite of what is expected in a client with SIADH, who typically presents with decreased urine output.
The nurse is caring for a client with syndrome of inappropriate antidiuretic hormone (SIADH). Which of the following clinical findings should the nurse expect?
- A. Hyponatremia
- B. Hyperkalemia
- C. Hypercalcemia
- D. Hypernatremia
Correct Answer: A
Rationale: In SIADH, there is excessive release of antidiuretic hormone (ADH), leading to water retention and dilutional hyponatremia. Hyponatremia is a hallmark finding in SIADH due to the imbalance between water and sodium levels. Hyperkalemia (Choice B) is not typically associated with SIADH. Hypercalcemia (Choice C) involves elevated calcium levels, which are not directly related to SIADH. Hypernatremia (Choice D) is the opposite of what occurs in SIADH, where sodium levels are usually diluted due to water retention.
What is the mechanism of action of corticotropin (Acthar) when prescribed as replacement therapy for a male client who has undergone surgical removal of a pituitary tumor?
- A. It decreases cyclic adenosine monophosphate (cAMP) production and affects the metabolic rate of target organs.
- B. It interacts with plasma membrane receptors to inhibit enzymatic actions.
- C. It interacts with plasma membrane receptors to produce enzymatic actions that affect protein, fat, and carbohydrate metabolism.
- D. It regulates the threshold for water reabsorption in the kidneys.
Correct Answer: C
Rationale: Corticotropin (ACTH) stimulates the adrenal cortex to secrete cortisol and other hormones, affecting protein, fat, and carbohydrate metabolism. Choice A is incorrect because corticotropin does not decrease cAMP production; instead, it stimulates enzymatic actions. Choice B is incorrect because corticotropin does not inhibit enzymatic actions but rather produces enzymatic actions. Choice D is incorrect because corticotropin's mechanism of action does not involve regulating the threshold for water reabsorption in the kidneys.
A client with type 1 diabetes mellitus presents to the emergency department with symptoms of diabetic ketoacidosis (DKA). Which of the following interventions should the nurse implement first?
- A. Administer intravenous insulin
- B. Start an intravenous line and infuse normal saline
- C. Monitor serum potassium levels
- D. Obtain an arterial blood gas (ABG)
Correct Answer: B
Rationale: The correct first intervention in a client with DKA is to start an intravenous line and infuse normal saline for fluid resuscitation. This is crucial to restore intravascular volume and improve perfusion, addressing the dehydration and electrolyte imbalances commonly seen in DKA. Administering insulin without addressing the dehydration can lead to further complications. Monitoring serum potassium levels is important but is not the first priority; potassium levels can shift with fluid resuscitation. Obtaining an arterial blood gas (ABG) is helpful in assessing acid-base status but is not the initial priority compared to fluid resuscitation.
A nurse manager in the emergency department considers policy changes in the organization and changes in the community, and tries to predict how these may impact the functioning of the unit. Which of the following decisional activities best describes this manager's actions?
- A. Resource allocation
- B. Monitoring
- C. Job analysis and redesign
- D. Planning for the future
Correct Answer: D
Rationale: The correct answer is 'Planning for the future.' In this scenario, the nurse manager is engaging in strategic planning by considering policy changes and community dynamics to forecast potential impacts on the unit's functioning. This decisional activity involves anticipating future changes, challenges, and opportunities, and preparing the unit to adapt accordingly.
Choice A, 'Resource allocation,' involves distributing resources effectively to support daily operations, which is not the primary focus of the nurse manager's actions described.
Choice B, 'Monitoring,' typically involves overseeing current activities and performance to ensure adherence to standards and goals, rather than proactively planning for future changes as the nurse manager is doing.
Choice C, 'Job analysis and redesign,' pertains to evaluating and modifying job roles and responsibilities within the unit, which is not directly related to the strategic forecasting and planning involved in anticipating organizational and community impacts.
