Nursing Elites

1. A client who has just had a mastectomy has a closed wound suction device (hemovac) in place. Which nursing action will ensure proper operation of the device?

• A. Collapsing the device whenever it is 1/2 to 2/3 full of air.
• B. Emptying the device every 4 hours.
• C. Replacing the device every 24 hours.
• D. Keeping the device above the level of the surgical site.

Correct answer: A

Rationale: Collapsing the device when it is 1/2 to 2/3 full of air is the correct nursing action to ensure proper operation of a closed wound suction device (hemovac). This action maintains negative pressure, which is essential for proper suction and drainage of the wound. Emptying the device every 4 hours (Choice B) is not necessary as the focus should be on collapsing it appropriately. Replacing the device every 24 hours (Choice C) is not a standard practice unless indicated by the healthcare provider. Keeping the device above the level of the surgical site (Choice D) is not necessary for the device's proper operation; collapsing it to maintain negative pressure is the key action.

2. A client asks a nurse about their Snellen eye test results. The client's visual acuity is 20/30. Which of the following responses should the nurse make?

• A. “Your eyes see at 20 feet what visually unimpaired eyes see at 30 feet.”
• B. “Your right eye can see the chart clearly at 20 feet, and your left eye can see the chart clearly at 30 feet.”
• C. “Your eyes see at 30 feet what visually unimpaired eyes see at 20 feet.”
• D. “Your left eye can see the chart clearly at 20 feet, and your right eye can see the chart clearly at 30 feet.”

Correct answer: A

Rationale: The correct answer is A: 'Your eyes see at 20 feet what visually unimpaired eyes see at 30 feet.' In the Snellen eye test, a visual acuity of 20/30 means that the client sees at 20 feet what a person with normal vision sees at 30 feet. This indicates that the client's vision is slightly worse than average. Choice B is incorrect as it incorrectly describes the visual acuity of each eye individually, rather than the combined visual acuity. Choice C is incorrect as it misinterprets the meaning of the Snellen eye test results by reversing the values. Choice D is incorrect as it inaccurately describes the visual acuity of the client's eyes, attributing different visual acuities to each eye instead of a combined measurement as indicated by 20/30.

3. A client with diabetes mellitus reports feeling anxious, shaky, and weak. These findings are manifestations of which of the following complications?

• A. Hyperglycemia
• B. Hypoglycemia
• C. Ketoacidosis
• D. Dawn phenomenon

Correct answer: B

Rationale: The correct answer is B, Hypoglycemia. In diabetes mellitus, hypoglycemia can lead to symptoms such as anxiety, shakiness, and weakness due to low blood sugar levels. Hyperglycemia (choice A) is high blood sugar levels and typically presents with symptoms like increased thirst and frequent urination. Ketoacidosis (choice C) is a serious complication of diabetes characterized by high levels of ketones in the blood, leading to symptoms such as fruity breath and rapid breathing. The Dawn phenomenon (choice D) refers to an abnormal early-morning increase in blood sugar levels without an associated hypoglycemia during the night.

4. The nurse has admitted a 4-year-old with the diagnosis of possible rheumatic fever. Which statement by the parent would cause the nurse to suspect an association with this disease?

• A. Our child had chickenpox 6 months ago.
• B. Strep throat went through all the children at the day care last month.
• C. Both ears were infected over 3 months ago.
• D. Last week both feet had a fungal skin infection.

Correct answer: B

Rationale: The correct answer is B. Rheumatic fever often follows a strep throat infection, which is why the nurse should suspect this association. Strep throat is caused by Group A Streptococcus bacteria, which can trigger an abnormal immune response leading to rheumatic fever. Choices A, C, and D are incorrect because chickenpox, ear infections, and fungal skin infections are not typically associated with rheumatic fever.

5. A client with diabetes mellitus is learning to self-administer insulin. Which action by the client indicates the need for further teaching?

• A. The client rotates injection sites on the abdomen.
• B. The client draws up the insulin dose after warming the vial to room temperature.
• C. The client pinches the skin before injecting the insulin.
• D. The client injects the insulin at a 90-degree angle.

Correct answer: B

Rationale: Drawing up insulin after warming the vial to room temperature indicates a need for further teaching, as insulin should be at room temperature for administration. Choice A is correct as rotating injection sites helps prevent lipodystrophy. Choice C is correct as pinching the skin helps ensure proper subcutaneous injection. Choice D is correct as injecting insulin at a 90-degree angle is the recommended technique for subcutaneous injections.
