Nursing Elites

1. 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.

2. 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.

3. The nurse is preparing to administer a subcutaneous injection of heparin. What is the correct angle of insertion?

• A. 15 degrees
• B. 30 degrees
• C. 45 degrees
• D. 90 degrees

Correct answer: C

Rationale: The correct angle of insertion for a subcutaneous injection, such as heparin, is 45 degrees. This angle is appropriate as it helps to ensure proper delivery of the medication into the subcutaneous tissue. Option A (15 degrees) is too shallow for a subcutaneous injection and may result in the medication being deposited into the muscle. Option B (30 degrees) is also too shallow for subcutaneous injections. Option D (90 degrees) is used for intramuscular injections, not subcutaneous injections.

4. When inserting an indwelling urinary catheter in a female client and urine flows into the tubing, what is the next action?

• A. Document the color and clarity of the urine
• B. Insert the catheter an additional inch
• C. Ask the client to breathe deeply and slowly exhale
• D. Inflate the balloon with 5 mL of sterile water

Correct answer: D

Rationale: When urine flows into the tubing during the insertion of an indwelling urinary catheter, it confirms proper catheter placement. The next step should be to inflate the balloon with the specified amount of sterile water to secure the catheter in place. Documenting the color and clarity of the urine (choice A) is important for assessment but not the immediate next action. Inserting the catheter further (choice B) without securing it could cause harm. Asking the client to breathe deeply (choice C) is not relevant to this situation.

5. A hospitalized toddler who is recovering from a sickle cell crisis holds a toy and says 'Mine'. According to Erikson's theory of psychosocial development, this child's behavior is a demonstration of which developmental stage?

• A. Autonomy vs. Shame and Doubt
• B. Industry vs. Inferiority
• C. Initiative vs. Guilt
• D. Trust vs. Mistrust

Correct answer: A

Rationale: The correct answer is A: Autonomy vs. Shame and Doubt. In Erikson's theory, toddlers aged 1-3 years are in the Autonomy vs. Shame and Doubt stage. During this stage, children begin to assert their independence and control over their environment. The behavior of the hospitalized toddler holding a toy and saying 'Mine' demonstrates the child's developing sense of autonomy and ownership. Choices B, C, and D correspond to different stages in Erikson's theory: Industry vs. Inferiority (school-age children), Initiative vs. Guilt (preschoolers), and Trust vs. Mistrust (infants), respectively, which are not applicable to the behavior described.
