1. Which vitamin deficiency is most associated with night blindness?

• A. Vitamin A
• B. Vitamin B12
• C. Vitamin C
• D. Vitamin D

Correct answer: A

Rationale: The correct answer is Vitamin A. Vitamin A deficiency leads to night blindness because this vitamin is crucial for the formation of rhodopsin, a photopigment in the retina. Rhodopsin is essential for vision in low-light conditions. Vitamin B12 deficiency can lead to anemia and neurological issues but is not directly related to night blindness. Vitamin C deficiency can cause scurvy, affecting connective tissues, but not night vision. Vitamin D deficiency can lead to bone disorders but is not primarily associated with night blindness.

2. A client post-mastectomy is concerned about the risk of lymphedema. What should the nurse include in the discharge instructions to minimize this risk?

• A. Wear compression garments on the affected arm.
• B. Avoid venipunctures and blood pressure measurements on the affected arm.
• C. Perform vigorous exercises to strengthen the affected arm.
• D. Keep the affected arm elevated at all times.

Correct answer: B

Rationale: To minimize the risk of lymphedema after a mastectomy, it is essential to instruct the client to avoid venipunctures and blood pressure measurements on the affected arm. These procedures can lead to trauma or impede lymphatic flow, increasing the risk of lymphedema. Wearing compression garments helps manage lymphedema but is not preventive. Performing vigorous exercises can strain the affected arm and increase the risk of lymphedema. Keeping the affected arm elevated at all times is unnecessary and not an effective preventive measure against lymphedema.

3. 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.

4. What is the best thing to say to a patient scheduled for cataract surgery who is concerned that the physician works on the correct eye?

• A. You are wearing an ID bracelet that will let the medical team know which eye to work on.
• B. When you are taken to the surgery area, the medical staff will confirm which eye needs the surgery.
• C. The surgeon will mark the correct eye before the cataract surgery based on your medical records.
• D. You will wear an ID bracelet, and the nurse will verify the eye scheduled for surgery by comparing it with your records and marking it with a permanent marker.

Correct answer: D

Rationale: The best response reassures the patient by explaining the process of verifying and marking the correct eye, a safety measure to prevent wrong-site surgery, directly addressing the patient’s concern. Choice A is close but implies the ID bracelet alone determines the correct eye, missing the verification process. Choice B talks about confirmation but lacks details about marking the correct eye. Choice C mentions the surgeon's record but does not specify the direct verification and marking process, unlike Choice D.

5. A client is recovering from a right-sided mastectomy and is concerned about lymphedema. What should the nurse include in the discharge teaching to minimize this risk?

• A. Encourage wearing tight clothing on the affected arm.
• B. Advise against lifting heavy objects with the affected arm.
• C. Recommend the client sleep on the affected side.
• D. Suggest frequent massage of the affected arm.

Correct answer: B

Rationale: The correct answer is B: Advise against lifting heavy objects with the affected arm. Lifting heavy objects with the affected arm can increase the risk of lymphedema. It is important for clients to avoid activities that strain the affected arm to minimize the risk of developing lymphedema. Choices A, C, and D are incorrect because wearing tight clothing on the affected arm, sleeping on the affected side, and frequent massage of the affected arm can potentially worsen lymphedema or impede the recovery process. Tight clothing can impede lymphatic flow, sleeping on the affected side can restrict circulation, and frequent massage can exacerbate swelling in the arm.
