Metformin (Glucophage) is administered to clients with type II diabetes mellitus. Metformin is an example of:
- A. an antihyperglycemic agent.
- B. a hypoglycemic agent.
- C. an insulin analogue.
- D. a pancreatic alpha cell stimulant
Correct Answer: A
Rationale: Metformin is classified as an antihyperglycemic agent because it works by reducing hepatic glucose output and decreasing glucose absorption from the gut, thereby preventing hyperglycemia. Choice B, a hypoglycemic agent, is incorrect as hypoglycemic agents stimulate insulin production, which is not the mechanism of action of metformin. Choice C, an insulin analogue, is incorrect as metformin is not a type of insulin but a distinct medication. Choice D, a pancreatic alpha cell stimulant, is incorrect as metformin does not stimulate any pancreatic cells, but rather acts on the liver and gut to lower blood sugar levels.

A mother who has never breastfed a child before is having trouble getting the baby to latch on to the breast. The baby has lost 3% of its birth weight within the first 2 days of life. The best statement is:
- A. The baby will eventually take to the breast.
- B. I can prepare a bottle if you want to try that.
- C. A small amount of weight loss in the first few days is normal.
- D. I can arrange for the charge nurse to come and talk to you about breastfeeding.
Correct Answer: C
Rationale: The correct answer is 'A small amount of weight loss in the first few days is normal.' It is important to reassure the mother that a small amount of weight loss, such as 5-10% of birth weight, in the first few days of life is considered normal for newborns. This reassurance helps alleviate the mother's concerns. Option A is incorrect because it does not address the concern about weight loss; it focuses more on the baby eventually latching on. Option B is not recommended as the first solution for breastfeeding issues, as introducing a bottle early on may lead to nipple confusion. Option D involves escalating the situation to the charge nurse when it can be addressed by providing appropriate information and support directly, making it less necessary in this scenario where reassurance and education are key.
A client newly diagnosed with Diabetes Mellitus needs education. Which of the following statements should the nurse include in this education?
- A. "You can eat anything you want, but avoid foods with sugar."?
- B. "You need to lose weight, so your diet must be controlled."?
- C. "You need a diet and exercise program."?
- D. "You must reduce salt, fat, and sugar intake in your diet."?
Correct Answer: C
Rationale: A client newly diagnosed with Diabetes Mellitus requires education on managing their condition. Choice C is the correct answer because it emphasizes the importance of a comprehensive approach involving both diet and exercise. This holistic approach is crucial in managing blood sugar levels and overall health for individuals with diabetes. Choice A is incorrect as it provides misleading information by suggesting that the client can eat anything as long as it doesn't contain sugar, which is not accurate for diabetes management. Choice B is not the best option as it focuses solely on weight loss rather than addressing the holistic needs of a diabetic individual. Choice D is incorrect as it suggests eliminating all salt, fat, and sugar, which is an extreme approach and not a realistic or balanced way to manage diabetes.
A nurse is instructing a patient on the order of sensations with the application of an ice water bath for a swollen right ankle. Which of the following is the correct order of sensations experienced with an ice water bath?
- A. cold, burning, aching, and numbness
- B. burning, aching, cold, and numbness
- C. aching, cold, burning, and numbness
- D. cold, aching, burning, and numbness
Correct Answer: A
Rationale: The correct order of sensations experienced with an ice water bath is cold, burning, aching, and numbness, as stated by the acronym CBAN (cold, burn, ache, numbness). Option A is the correct sequence. Choice B is incorrect as it starts with burning, which typically follows the cold sensation. Choice C is incorrect as aching is usually felt after the burning sensation. Choice D is incorrect as aching usually occurs after the burning sensation.
When a person using over-the-counter nasal decongestant drops experiences unrelieved and worsening nasal congestion, what should be instructed?
- A. switch to a stronger dose of the same medication.
- B. discontinue the medication for a few weeks.
- C. continue taking the same medication, but use it more frequently.
- D. use a combination of medications for better relief.
Correct Answer: B
Rationale: When a person using over-the-counter nasal decongestant drops experiences unrelieved and worsening nasal congestion, it is crucial to discontinue the medication for a few weeks. Prolonged use of decongestant drops can lead to rebound congestion, which is relieved by stopping the medication for a period of time. Nasal congestion occurs due to various factors like infection, inflammation, or allergy, leading to swelling of the nasal cavity. Nasal decongestants work by stimulating alpha-adrenergic receptors, causing vasoconstriction and shrinking of nasal mucous membranes. However, prolonged use can result in vasodilation, worsening nasal congestion. Switching to a stronger dose of the same medication is not recommended as it can exacerbate the issue. Continuing the same medication more frequently or using a combination of medications are also not advised and may lead to side effects. Educating individuals on proper decongestant use and potential risks of prolonged usage is essential, especially for those with specific health conditions.
A 32-year-old male with a complaint of dizziness has an order for Morphine via IV. What should the nurse do first?
- A. Check the patient's chest x-ray results.
- B. Retake vitals including blood pressure.
- C. Perform a neurological screening on the patient.
- D. Request the physician on-call to assess the patient.
Correct Answer: B
Rationale: The correct first action for the nurse to take in this situation is to retake the patient's vitals, including blood pressure. Dizziness can be a sign of hypotension, which may be a contraindication for administering Morphine. Checking the chest x-ray results (Choice A) would not be the priority in this case as addressing the dizziness is more urgent. Performing a neurological screening (Choice C) may be important but not the first step when a patient presents with dizziness and an order for Morphine. Requesting the physician to assess the patient (Choice D) should come after the initial assessment and vitals retake.
