When a patient who takes metformin (Glucophage) to manage type 2 diabetes develops an allergic rash from an unknown cause, the healthcare provider prescribes prednisone (Deltasone). The nurse will anticipate that the patient may

Correct Answer: C

Rationale: Rationale for Correct Answer C (require administration of insulin while taking prednisone): 1. Prednisone can increase blood glucose levels by reducing insulin sensitivity. 2. Metformin alone may not control blood glucose levels adequately in the presence of prednisone. 3. Therefore, the patient may require insulin to manage blood glucose levels while on prednisone. Summary of Incorrect Choices: A: This is incorrect because insulin administration is not necessary due to the rash or the interaction between metformin and prednisone. B: This is incorrect because prednisone can actually increase blood glucose levels, leading to hyperglycemia rather than hypoglycemia. D: This is incorrect because the rash is not likely caused by an interaction between metformin and prednisone, but rather an allergic reaction to an unknown cause.

Correct Answer: B

Rationale: The correct answer is B: Candidates. Candidates are individuals who are running for election and seeking to be elected to a specific position. They are the ones whose names appear on the voting ballot for voters to choose from. Representatives (A) are individuals who have already been elected to represent a group or constituency. Bargaining agents (C) are individuals who negotiate on behalf of others, typically in labor relations. The electorate (D) refers to all the eligible voters in a particular election, not the individuals who are running for election. Therefore, B is the correct answer as it specifically identifies the individuals seeking election on a voting ballot.

Correct Answer: D

Rationale: The correct answer is D: Autocratic leadership. In a high-stress, time-sensitive situation like a multiple-car accident with multiple trauma clients, autocratic leadership is most effective due to its clear chain of command and quick decision-making. The leader can provide swift direction, prioritize tasks, and ensure immediate action to save lives. Democratic leadership (A) may lead to delays in decision-making. Bureaucratic leadership (B) focuses on following procedures, which may not be suitable for urgent situations. Laissez-faire leadership (C) lacks direction and can result in chaos in a crisis.

Correct Answer: B

Rationale: The correct answer is B because amitriptyline is a tricyclic antidepressant that works by inhibiting the reuptake of serotonin and norepinephrine, thus helping to prevent the transmission of pain impulses to the brain. This mechanism of action is effective in managing neuropathic pain, such as burning foot pain in diabetic patients. Choices A, C, and D are incorrect because amitriptyline's primary mechanism of action is related to its effects on neurotransmitter reuptake, not directly related to mood improvement, blood vessel changes, or sleep improvement.

Correct Answer: C

Rationale: The correct answer is C: Shared decision making. Shared governance involves collaborative decision-making among healthcare professionals, including nurses, to improve patient care and organizational outcomes. This approach empowers frontline staff to have a voice in decisions that affect their work environment and patient care. Nurse-led committees (option B) may be a part of shared governance but do not fully encompass the concept. Top-down management (option A) and hierarchical structure (option D) are opposite to the principles of shared governance as they involve centralized decision-making and lack of employee involvement in decision-making processes.

Correct Answer: D

Rationale: The correct answer is D: Contingency theory. Contingency theory suggests that there is no one best way to organize and manage a healthcare system. It emphasizes that the effectiveness of a healthcare delivery system depends on various factors such as the environment, technology, and organizational structure. This theory acknowledges the complexity of healthcare systems and the need for flexibility and adaptation to changing circumstances. A: Open system theory focuses on the system's interaction with its environment, but it does not specifically address the best way to organize and manage a healthcare system. B: Closed system theory suggests that a system is self-contained and not influenced by external factors, which is not suitable for describing healthcare delivery systems. C: Chaos theory emphasizes the unpredictability and complexity of systems, but it does not provide a framework for organizing and managing healthcare systems effectively.

Correct Answer: C

Rationale: The correct answer is C. Encouraging the adolescent's guardian to assist with personal hygiene is crucial after a lumbar laminectomy. Postoperatively, the adolescent may require assistance with activities of daily living due to limited mobility and risk of injury. Involving the guardian ensures proper care and promotes faster recovery. Choice A is incorrect as limiting visitors can negatively impact the adolescent's emotional well-being and support system. Choice B is incorrect as food choices are not typically restricted postoperatively unless medically necessary. Choice D is incorrect as the adolescent may not be in the optimal state to make decisions regarding their daily routine immediately after surgery.

Correct Answer: C

Rationale: Rationale for Correct Answer C (require administration of insulin while taking prednisone): 1. Prednisone can increase blood glucose levels by reducing insulin sensitivity. 2. Metformin alone may not control blood glucose levels adequately in the presence of prednisone. 3. Therefore, the patient may require insulin to manage blood glucose levels while on prednisone.

D: This is incorrect because the rash is not likely caused by an interaction between metformin and prednisone, but rather an allergic reaction to an unknown cause.

Correct Answer: A

Rationale: The correct answer is A: Use antimicrobial sanitizer for hand hygiene. Hand hygiene is crucial in preventing the spread of tuberculosis. TB is transmitted through respiratory droplets, not contact, so wearing a mask (choice B) is not effective. Limiting visitor time (choice C) may help reduce exposure, but hand hygiene is more critical. Wearing gloves for oral care (choice D) is important for standard precautions, but hand hygiene is the priority for TB prevention.
