Nursing Elites

1. 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.

2. A nurse manager works hard to keep employee morale high with the thought that this will lead to effective employees doing the best work they can. Which of the following theories does this best describe?

• A. Theory X
• B. Theory Y
• C. Servant leadership
• D. Scientific management

Correct answer: B

Rationale: Theory Y, as proposed by Douglas McGregor, emphasizes that employees are intrinsically motivated and seek responsibility. It suggests that high morale leads to high productivity, aligning with the nurse manager's actions. Theory X, on the other hand, assumes employees are inherently lazy and need to be closely monitored and controlled. Servant leadership focuses on serving others first and prioritizing their needs, which is not directly related to the scenario described. Scientific management, developed by Frederick Taylor, emphasizes efficiency and standardization through systematic study and organizational control, which is not the primary focus of the nurse manager's approach to boosting employee morale.

3. 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 D: Planning for the future. In this scenario, the nurse manager is engaging in decisional activities related to planning for the future. This involves analyzing potential impacts of policy changes and community shifts on the unit's functioning and making decisions based on predictions and foresight. Option A, resource allocation, focuses on distributing resources effectively. Option B, monitoring, involves observing and assessing current activities. Option C, job analysis and redesign, pertains to evaluating and restructuring roles and responsibilities within the unit, which is not the primary focus of the scenario provided.

4. 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.

5. A patient with acute congestive heart failure is receiving high doses of a diuretic. On assessment, the nurse notes flat neck veins, generalized muscle weakness, and diminished deep tendon reflexes. Suspecting hyponatremia, what additional signs would the nurse expect to note in this patient if hyponatremia were present?

• A. Dry skin
• B. Decreased urinary output
• C. Hyperactive bowel sounds
• D. Increased specific gravity of the urine

Correct answer: C

Rationale: In a patient with hyponatremia, hyperactive bowel sounds are expected due to increased gastrointestinal motility. Dry skin (Choice A) is not a typical sign of hyponatremia. Decreased urinary output (Choice B) is more commonly associated with conditions like dehydration or renal issues, not specifically hyponatremia. Increased specific gravity of the urine (Choice D) is a sign of concentrated urine, which is not a characteristic finding in hyponatremia.
