1. The nurse is providing care for a client with type 1 diabetes mellitus who is receiving NPH insulin. The nurse notices that the client's evening glucose levels are consistently above 260 mg/dl. What does this indicate?
- A. States that her feet are constantly cold and feel numb
- B. A wound on the ankle that starts to drain and becomes painful
- C. Consecutive evening serum glucose greater than 260 mg/dl
- D. Reports nausea in the morning but still able to eat breakfast
Correct answer: C
Rationale: High evening glucose levels suggest that the current insulin dosage may be inadequate to control the client's blood sugar levels effectively. This indicates poor glycemic control and the need for a possible adjustment in the insulin regimen. Option A describes symptoms of peripheral neuropathy, which are not directly related to the elevated glucose levels but may be a long-term complication of diabetes. Option B describes a wound infection, which is not directly related to the client's high glucose levels. Option D mentions morning nausea, which could be due to various causes and is not directly related to the high evening glucose levels.
2. When administering IV fluids to a client with a history of congestive heart failure (CHF), what is the nurse's primary concern?
- A. Monitoring for signs of fluid overload.
- B. Ensuring the client receives enough fluids to prevent dehydration.
- C. Preventing electrolyte imbalances.
- D. Maintaining the prescribed rate of fluid administration.
Correct answer: A
Rationale: The primary concern when administering IV fluids to a client with a history of congestive heart failure (CHF) is monitoring for signs of fluid overload. Clients with CHF are particularly vulnerable to fluid overload, which can exacerbate their condition. Signs of fluid overload include edema and difficulty breathing. Therefore, the nurse must closely monitor these signs to prevent worsening of the client's condition. Choices B, C, and D are incorrect because while ensuring hydration, preventing electrolyte imbalances, and maintaining the prescribed rate of fluid administration are important, they are secondary concerns compared to the critical task of monitoring for fluid overload in a client with CHF.
3. While providing oral care for a client who is unconscious, the nurse positions the client laterally and uses a basin to collect secretions. Which intervention is best for the nurse to implement?
- A. Swab the oral cavity with a washcloth
- B. Use oral swabs with normal saline
- C. Provide a Yankauer tip for oral suction
- D. Support the head with a small pillow
Correct answer: B
Rationale: Using oral swabs with normal saline is the best intervention in this scenario as it effectively cleans the oral cavity without causing irritation or dryness, which is crucial for an unconscious client. Swabbing the oral cavity with a washcloth may not provide thorough cleaning, and it can potentially cause irritation. Providing a Yankauer tip for oral suction is not necessary unless there are excessive secretions that need to be suctioned. Supporting the head with a small pillow, although important for comfort, is not directly related to oral care in an unconscious client.
4. When preparing to administer a medication through a nasogastric (NG) tube, what is the first action the nurse should take?
- A. Check the placement of the NG tube
- B. Flush the tube with saline
- C. Position the client in a semi-Fowler's position
- D. Administer the medication slowly
Correct answer: A
Rationale: The correct first action when preparing to administer a medication through a nasogastric (NG) tube is to check the placement of the NG tube. This step is essential to ensure that the tube is correctly positioned in the stomach and not in the lungs, preventing potential complications. Flushing the tube with saline may be required, but it should follow the verification of tube placement. Positioning the client in a semi-Fowler's position is necessary for comfort during the procedure but is not the initial step. Administering the medication can only be done safely after confirming the correct placement of the NG tube.
5. What is the primary function of surfactant in the lungs?
- A. Reduce surface tension
- B. Enhance oxygen absorption
- C. Facilitate carbon dioxide release
- D. Increase lung volume
Correct answer: A
Rationale: The primary function of surfactant in the lungs is to reduce surface tension in the alveoli. This reduction in surface tension prevents lung collapse and allows for easier breathing. It is particularly crucial in premature infants to help with lung expansion. Choice B is incorrect because surfactant primarily affects surface tension, not oxygen absorption. Choice C is incorrect because surfactant's main role is not in facilitating carbon dioxide release. Choice D is incorrect because surfactant does not directly increase lung volume; its main role is in reducing surface tension.
