Question 1 of 5
A patient with type 2 diabetes mellitus asks the nurse how metformin decreases blood sugar. What is the best response by the nurse?
Correct Answer: A
Rationale: Metformin primarily works by decreasing hepatic glucose production and improving insulin sensitivity in peripheral tissues. It does not increase insulin resistance (B), block carbohydrate absorption (C), or stimulate insulin release (D). These mechanisms help lower blood glucose levels in patients with type 2 diabetes.
Question 2 of 5
Which of the following is most effective as a topical agent for a candida infection of the skin?
Correct Answer: D
Rationale: Cutaneous candidiasis needs topical antifungals. Griseofulvin treats dermatophytes orally, not candida topically. Beclometasone, a steroid, worsens fungal growth. Aciclovir targets herpes, not fungi. Amphotericin is IV for systemic use. Nystatin binds ergosterol in candida membranes, most effective topically for skin infections, widely used for its specificity and safety.
Question 3 of 5
A client is to receive enteral nutrition. Which information should the nurse provide to the client and family?
Correct Answer: A
Rationale: Enteral nutrition involves delivering nutrients directly into the gastrointestinal tract, typically via a tube, and can be administered intermittently (e.g., bolus feedings) or continuously (e.g., via a pump), offering flexibility based on the client's needs and tolerance. This method contrasts with parenteral nutrition, which uses veins, making the venous administration statement inaccurate for enteral feeding. The purpose of enteral nutrition often includes supporting clients who cannot swallow adequately-due to conditions like dysphagia-ensuring they receive sufficient calories and nutrients to prevent malnutrition. However, enteral feedings are typically formula-based, not thinned pureed food, as specialized formulas provide balanced nutrition tailored to medical needs, unlike pureed diets which are less common in tube feeding. The intermittent or continuous delivery option is key education, as it addresses how the therapy adapts to lifestyle and clinical status, providing practical understanding for the client and family while clarifying enteral nutrition's gastrointestinal focus over intravenous methods.
Question 4 of 5
The client is receiving a brand name drug and wants to change to the generic form because it is cheaper. What is the best outcome for this client?
Correct Answer: A
Rationale: Understanding two differences (e.g., cost, inactive ingredients) between brand and generic drugs empowers the client to make informed choices, the best outcome. Sticking to brand after physician talk assumes preference. Asking why brand is better misaligns-generics are equivalent. Cost reduction methods are practical but secondary to comprehension. Knowledge of differences supports the switch, aligning with cost-saving goals.
Question 5 of 5
An adolescent patient comes to the school nurse with complaints of vague abdominal pain. What assessment data would help to confirm the nurse's suspicion that the adolescent has body image concerns?
Correct Answer: A
Rationale: Body image concerns in adolescents often tie to eating-defensiveness about food scrutiny suggests disordered eating (e.g., anorexia), linking pain to image stress. Sexual activity, irregular periods, or parent conflicts point elsewhere-STI, hormonal issues, or family tension. Food focus signals image worry, per developmental psychology.
