Nursing Elites

1. A client with type 2 diabetes mellitus is taking metformin. The nurse should monitor the client for which of the following potential side effects?

• A. Lactic acidosis
• B. Hypokalemia
• C. Hyperglycemia
• D. Weight gain

Correct answer: A

Rationale: The correct answer is A: Lactic acidosis. Metformin, a common medication for type 2 diabetes mellitus, can lead to lactic acidosis, particularly in individuals with renal impairment or other predisposing factors. Monitoring for signs and symptoms of lactic acidosis, such as muscle pain, weakness, trouble breathing, dizziness, and slow or irregular heartbeat, is crucial when a client is taking metformin. Choice B, hypokalemia, is not a common side effect of metformin. Choice C, hyperglycemia, is contrary to the intended effect of metformin, which is to lower blood glucose levels. Choice D, weight gain, is not typically associated with metformin use; in fact, metformin may even contribute to weight loss in some individuals.

2. The client with DM who is taking insulin develops a fever and becomes confused. Which action should the nurse take first?

• A. Check the client's blood glucose level.
• B. Administer a fever-reducing medication.
• C. Give the client fluids to drink.
• D. Notify the health care provider.

Correct answer: A

Rationale: In a client with diabetes mellitus (DM) taking insulin, the development of fever and confusion may indicate hyperglycemia or diabetic ketoacidosis. Checking the blood glucose level is the priority action in this situation. This will help determine if the symptoms are related to high blood sugar levels, guiding further interventions. Administering a fever-reducing medication (choice B) addresses only the symptom of fever and does not address the underlying cause. Providing fluids to drink (choice C) is important but should come after addressing the potential hyperglycemia or diabetic ketoacidosis. Notifying the health care provider (choice D) can be important, but immediate action to evaluate and manage the client's condition should precede contacting the provider.

3. Which of the following ethical principles is involved when a healthcare provider allows a patient to refuse treatment?

• A. Autonomy
• B. Nonmaleficence
• C. Beneficence
• D. Justice

Correct answer: A

Rationale: The correct answer is A: Autonomy. Autonomy is the ethical principle that respects an individual's right to make their own decisions, including the right to refuse treatment. This principle acknowledges the patient's self-governance and independence in making choices about their own healthcare. Choice B, Nonmaleficence, refers to the ethical principle of doing no harm and ensuring patient safety. Choice C, Beneficence, involves promoting the patient's well-being and acting in their best interest. Choice D, Justice, pertains to fairness and equitable distribution of healthcare resources.

4. A client with hyperthyroidism is prescribed propranolol. The nurse understands that this medication is used to:

• A. Increase metabolism
• B. Reduce anxiety
• C. Decrease heart rate
• D. Increase blood pressure

Correct answer: C

Rationale: Propranolol is a beta-blocker commonly used in the management of hyperthyroidism. It works by blocking the effects of adrenaline, resulting in a decrease in heart rate and blood pressure. Choice A is incorrect because propranolol does not increase metabolism; instead, it may have a mild inhibitory effect. Choice B is incorrect as propranolol is not primarily used to reduce anxiety, although it may have some anxiolytic effects. Choice D is incorrect as propranolol actually decreases blood pressure by blocking the effects of adrenaline on the heart and blood vessels.

5. Why is glucose an important molecule in a cell?

• A. Extraction of energy
• B. Synthesis of protein
• C. Building of genetic material
• D. Formation of cell membranes

Correct answer: A

Rationale: Glucose is a crucial molecule in cells because it serves as the primary source of energy through cellular respiration. Choice B, the synthesis of protein, is incorrect because proteins are typically synthesized from amino acids, not glucose. Choice C, the building of genetic material, is incorrect because genetic material, such as DNA and RNA, is not directly built from glucose. Choice D, the formation of cell membranes, is also incorrect as cell membranes are primarily composed of lipids and proteins, not glucose.
