Nursing Elites

1. A client is prescribed metformin for the management of type 2 diabetes. What is the primary action of this medication?

• A. Stimulates insulin secretion from the pancreas.
• B. Increases insulin sensitivity in various tissues.
• C. Decreases hepatic glucose production.
• D. Delays absorption of glucose from the intestines.

Correct answer: C

Rationale: The correct answer is C: Decreases hepatic glucose production. Metformin primarily works by reducing the production of glucose in the liver (hepatic glucose production) and by improving insulin sensitivity in various tissues. Choice A is incorrect as metformin does not stimulate insulin secretion from the pancreas. Choice B is incorrect as metformin increases insulin sensitivity in various tissues, not just muscle cells. Choice D is incorrect as metformin does not delay glucose absorption from the intestines.

2. A client with a history of chronic obstructive pulmonary disease (COPD) is prescribed oxygen therapy at 2 liters per minute via nasal cannula. What is the most important instruction the nurse should provide?

• A. Increase the oxygen flow rate if shortness of breath occurs
• B. Use oxygen only when experiencing shortness of breath
• C. Do not adjust the oxygen flow rate without consulting a healthcare provider
• D. Use a humidifier with the oxygen to prevent dry mucous membranes

Correct answer: C

Rationale: The most important instruction the nurse should provide to a client with COPD prescribed oxygen therapy is not to adjust the oxygen flow rate without consulting a healthcare provider. This is crucial because too much oxygen can suppress the client's respiratory drive, leading to further complications. Choice A is incorrect because increasing the oxygen flow rate without medical advice can be harmful. Choice B is incorrect as oxygen therapy should be used as prescribed, not just when symptoms occur. Choice D is incorrect as the priority is to ensure the correct oxygen flow rate rather than using a humidifier.

3. A client with hypothyroidism is taking levothyroxine (Synthroid). Which symptom should prompt the nurse to notify the healthcare provider?

• A. Weight gain
• B. Bradycardia
• C. Nervousness and tremors
• D. Fatigue

Correct answer: C

Rationale: The correct answer is C: Nervousness and tremors. These symptoms may indicate hyperthyroidism resulting from excessive dosing of levothyroxine. Weight gain (Choice A) is a common symptom of hypothyroidism and may indicate undertreatment or inadequate dosing. Bradycardia (Choice B) is a symptom of hypothyroidism and may improve with levothyroxine therapy; it does not typically indicate an urgent need for healthcare provider notification. Fatigue (Choice D) is a symptom of hypothyroidism and can persist even with levothyroxine treatment, so it is not a symptom that would require immediate notification of the healthcare provider.

4. The nurse is assessing a newborn and notes that the infant has a yellowish tint to the skin. What should the nurse do next?

• A. Reassure the parents that this is normal
• B. Monitor the infant's bilirubin levels
• C. Increase the frequency of feedings
• D. Administer phototherapy

Correct answer: B

Rationale: When a newborn presents with a yellowish tint to the skin, it can indicate jaundice, which is caused by elevated bilirubin levels. Monitoring the infant's bilirubin levels is crucial to assess the severity of jaundice and determine the need for further intervention. Reassuring the parents without proper assessment could lead to delayed treatment if jaundice is present. Increasing the frequency of feedings may not address the underlying cause of jaundice. Administering phototherapy is a treatment option that should be based on bilirubin level assessment and healthcare provider's recommendation.

5. A client with a diagnosis of hypothyroidism is prescribed levothyroxine (Synthroid). What is the most important instruction the nurse should provide?

• A. Take the medication in the morning on an empty stomach
• B. Take the medication with food
• C. Report any symptoms of hyperthyroidism
• D. Do not discontinue the medication abruptly

Correct answer: C

Rationale: The correct answer is C: 'Report any symptoms of hyperthyroidism.' Symptoms of hyperthyroidism, such as palpitations or tremors, may indicate an excessive dose of levothyroxine and should be reported to the healthcare provider for proper adjustment of the medication. Choice A is incorrect because levothyroxine is usually taken in the morning on an empty stomach to maximize absorption. Choice B is incorrect because taking levothyroxine with food can interfere with its absorption. Choice D is incorrect because discontinuing levothyroxine abruptly can lead to a worsening of hypothyroidism symptoms.
