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 syndrome of inappropriate antidiuretic hormone (SIADH) is at risk for which of the following complications?
- A. Hypernatremia
- B. Hyponatremia
- C. Hyperkalemia
- D. Hypercalcemia
Correct Answer: B
Rationale: The correct answer is B: Hyponatremia. Syndrome of inappropriate antidiuretic hormone (SIADH) is characterized by the excessive release of antidiuretic hormone (ADH), leading to water retention in the body. This causes dilutional hyponatremia, where the sodium levels in the blood become abnormally low. Option A, Hypernatremia, is incorrect because SIADH does not cause elevated sodium levels. Option C, Hyperkalemia, is incorrect as SIADH does not directly affect potassium levels. Option D, Hypercalcemia, is also incorrect as SIADH does not impact calcium levels.
Nurse managers need several qualities to be effective. A nurse manager is working hard to fully understand how patient outcomes are measured on the unit and how budget changes could impact patient outcomes. Which of the following qualities does this best describe?
- A. Leadership
- B. Business sense
- C. Clinical expertise
- D. Financial management
Correct Answer: B
Rationale: The correct answer is 'Business sense.' Nurse managers need to understand how financial decisions impact patient outcomes, which requires a strong understanding of business principles. Leadership (choice A) is important but doesn't specifically address understanding financial and outcome-based impacts. Clinical expertise (choice C) is essential for patient care but doesn't directly relate to understanding budget changes and their impact. Financial management (choice D) is more about managing finances directly rather than understanding the broader implications of budget changes on patient outcomes.
A client with type 1 DM is admitted to the hospital with diabetic ketoacidosis (DKA). The nurse should prioritize which action?
- A. Administering intravenous fluids.
- B. Administering oral glucose.
- C. Administering a fever-reducing medication.
- D. Administering oxygen therapy.
Correct Answer: A
Rationale: Administering intravenous fluids is the priority in treating DKA for several reasons. DKA is characterized by severe dehydration and electrolyte imbalances due to hyperglycemia. IV fluids help to correct dehydration, restore electrolyte balance, and decrease blood glucose levels. Administering oral glucose (Choice B) would be contraindicated in DKA as the primary issue is high blood glucose levels. Administering a fever-reducing medication (Choice C) is not the priority in managing DKA. Administering oxygen therapy (Choice D) may be necessary in some cases, but correcting dehydration and electrolyte imbalances take precedence in the management of DKA.
Which of the following best describes the nurse's role in maintaining patient dignity?
- A. The nurse ensures that the patient is treated with respect and that their personal beliefs and values are considered in their care.
- B. The nurse maintains the patient's dignity by ensuring privacy during personal care activities.
- C. The nurse ensures that the patient's personal information is kept private and only shared with those directly involved in their care.
- D. The nurse ensures that the patient is involved in decisions about their care and that their preferences are respected.
Correct Answer: A
Rationale: The correct answer is A. The nurse's role in maintaining patient dignity goes beyond just privacy during personal care activities. It involves treating the patient with respect, considering their personal beliefs and values in their care. While privacy is important for dignity, respecting personal beliefs and values is equally crucial. Choice B focuses solely on privacy, overlooking the broader aspects of dignity maintenance. Choices C and D, although important in patient care, do not fully capture the comprehensive approach needed for maintaining patient dignity as described in choice A.
How often should rotation sites for insulin injection be separated from one another?
- A. Every third day.
- B. Every week.
- C. Every 2-3 weeks.
- D. Every 2-4 weeks.
Correct Answer: C
Rationale: Insulin injection sites should be rotated every 2-3 weeks to prevent lipodystrophy and ensure proper insulin absorption. Option A ('Every third day') is too frequent and does not allow enough time for the previous site to heal properly. Option B ('Every week') might not provide adequate time for the tissue to recover. Option D ('Every 2-4 weeks') could potentially lead to overuse of a single injection site, increasing the risk of lipodystrophy and inconsistent insulin absorption. Therefore, the recommended interval of every 2-3 weeks is optimal for insulin injection site rotation.
