Nursing Elites

1. 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.

2. Which of the following statements is true regarding ethical principles and laws?

• A. The government enforces ethics.
• B. Laws establish standards that aid in decision-making.
• C. Ethics are highly specific.
• D. Ethical principles can serve as the foundation for laws.

Correct answer: D

Rationale: The correct answer is D. Ethical principles can influence the creation of laws but are not equivalent to laws themselves. Laws are established by governing bodies to provide a framework for society, whereas ethical principles guide individuals' moral conduct. Choice A is incorrect because governments enforce laws, not ethics. Choice B is incorrect as laws set legal standards rather than ethical ones. Choice C is incorrect because ethics are principles that guide behavior but are not necessarily highly specific.

3. A client with type 1 DM is experiencing hypoglycemia. Which symptom should the nurse expect to observe?

• A. Tachycardia
• B. Polyuria
• C. Flushed skin
• D. Dry mouth

Correct answer: A

Rationale: The correct answer is A: Tachycardia. In hypoglycemia, the body releases adrenaline in response to low blood glucose levels, leading to symptoms such as tachycardia (rapid heart rate). Choice B, polyuria, refers to excessive urination and is not a typical symptom of hypoglycemia. Choice C, flushed skin, is not a common symptom of hypoglycemia; instead, pale skin and sweating are more characteristic. Choice D, dry mouth, is not directly associated with hypoglycemia; rather, it can be a symptom of hyperglycemia or dehydration.

4. The client has hyperparathyroidism. Which of the following lab findings is consistent with this condition?

• A. Hypocalcemia
• B. Hypercalcemia
• C. Hypokalemia
• D. Hyperphosphatemia

Correct answer: B

Rationale: Hyperparathyroidism leads to increased secretion of parathyroid hormone, which results in elevated calcium levels in the blood (hypercalcemia). Therefore, the correct lab finding consistent with hyperparathyroidism is hypercalcemia (Choice B). Hypocalcemia (Choice A) is not indicative of hyperparathyroidism as the condition is associated with high calcium levels. Hypokalemia (Choice C) is a low potassium level, which is not typically associated with hyperparathyroidism. Hyperphosphatemia (Choice D) refers to high phosphate levels and is not a characteristic finding in hyperparathyroidism.

5. Which of the following statements should be included in the teaching to a client about a do-not-resuscitate order (DNR)?

• A. When a heart ceases to beat, the client is pronounced clinically dead.
• B. Physicians are required to write DNR orders.
• C. A DNR order can be written after discussion with the client and family.
• D. A court decision is needed for a DNR.

Correct answer: C

Rationale: The correct statement to include in teaching a client about a do-not-resuscitate (DNR) order is that it can be written after discussion with the client and family. This involves ensuring that the client and their family understand the implications and make an informed decision. Choice A is incorrect as pronouncing clinical death is not directly related to discussing a DNR order. Choice B is incorrect as while physicians typically write DNR orders, it is not a strict requirement. Choice D is incorrect as a court decision is not typically required for a DNR order; it is a decision made by the client with input from healthcare providers and family members.
