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. Jemma, who weighs 210 lb (95 kg) and has been diagnosed with hyperglycemia tells the nurse that her husband sleeps in another room because her snoring keeps him awake. The nurse notices that she has large hands and a hoarse voice. Which of the following would the nurse suspect as a possible cause of the client's hyperglycemia?

• A. Acromegaly
• B. Type 1 diabetes mellitus
• C. Hypothyroidism
• D. Deficient growth hormone

Correct answer: A

Rationale: The correct answer is Acromegaly. Jemma's symptoms of large hands, hoarse voice, and snoring are indicative of acromegaly, a disorder caused by excessive growth hormone production. Acromegaly can lead to insulin resistance, which can result in hyperglycemia. Choice B, Type 1 diabetes mellitus, is unlikely in this case as the symptoms and presentation are more suggestive of acromegaly. Choice C, Hypothyroidism, typically presents with different symptoms such as weight gain, fatigue, and cold intolerance, not consistent with Jemma's symptoms. Choice D, Deficient growth hormone, would not lead to the signs and symptoms observed in Jemma, as her condition is characterized by excessive growth hormone production.

3. The healthcare provider is monitoring a client with diabetic ketoacidosis (DKA). Which of the following laboratory findings would be expected?

• A. Decreased blood glucose levels
• B. Decreased urine ketones
• C. Increased serum bicarbonate
• D. Increased anion gap

Correct answer: D

Rationale: In diabetic ketoacidosis (DKA), there is an excess of ketone bodies produced due to the breakdown of fatty acids for energy, leading to metabolic acidosis. An increased anion gap is a characteristic laboratory finding in DKA. The increased anion gap is a result of the accumulation of ketoacids and lactic acid in the blood, contributing to metabolic acidosis. Therefore, the correct answer is an increased anion gap. Choices A, B, and C are incorrect because in DKA, blood glucose levels are typically elevated, urine ketones are increased due to the breakdown of fatty acids, and serum bicarbonate is usually decreased as it is consumed in an attempt to buffer the acidosis.

4. A client with DM is preparing for a foot care exam. The nurse should advise the client to:

• A. Wear loose-fitting shoes to protect the feet.
• B. Apply lotion to the tops and bottoms of the feet to keep the skin moist.
• C. Avoid using a heating pad to prevent burns on the feet.
• D. Avoid using sharp instruments to trim the toenails.

Correct answer: D

Rationale: The correct answer is to advise the client to avoid using sharp instruments to trim the toenails. This is crucial because using sharp instruments can lead to injuries such as cuts or wounds, increasing the risk of infections, especially in clients with diabetes who have decreased sensation in their feet. Choice A is incorrect because tight shoes can restrict circulation and increase the risk of pressure sores. Choice B is incorrect because applying lotion between the toes can create a moist environment, leading to fungal infections. Choice C is incorrect because using a heating pad can lead to burns, which can go unnoticed due to decreased sensation in diabetic feet.

5. 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.
