HESI RN Nursing Leadership and Management Exam 6
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. Scientific management and human relations-based approach are two major theoretical management schools of thought. Which of the following best describes the scientific model of management?
- A. A nurse manager considers methods of motivating the staff to do their assigned tasks.
- B. A nurse manager commends staff for the work they do, reminding them of the importance of their work and the lives they have saved.
- C. A nurse manager analyzes the role of each staff member on the unit to determine ways to increase efficiency.
- D. A conflict between two staff nurses has impacted an entire unit. The unit manager meets with the nurses and entire staff to promote mutual understanding.
Correct answer: C
Rationale: The correct answer is C because scientific management focuses on improving efficiency through the analysis of tasks and work processes. Choice A is more aligned with a human relations-based approach, which emphasizes motivation and relationships. Choice B reflects recognition and morale boosting, which is also characteristic of the human relations approach. Choice D involves conflict resolution and promoting mutual understanding, which is related to the human relations approach rather than scientific management.
3. The nurse is preparing to administer NPH insulin to a client. The nurse should administer the insulin at which site for the best absorption?
- A. The deltoid muscle
- B. The anterior thigh
- C. The abdomen
- D. The gluteal muscle
Correct answer: C
Rationale: The abdomen is the preferred site for insulin injection due to its consistent absorption rate. Insulin injected into the abdomen is absorbed more consistently and predictably than in other sites. The deltoid muscle and the anterior thigh are not recommended for insulin injections due to inconsistent absorption rates. The gluteal muscle is avoided for insulin injections due to the risk of hitting the sciatic nerve or causing discomfort to the client.
4. 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.
5. 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.
