Nursing Elites

1. A client with diabetes mellitus is being taught by a nurse how to perform a capillary blood glucose test. Which of the following instructions should the nurse include in the teaching?

• A. Don sterile gloves after cleansing the site
• B. Puncture the site after cleansing and before the antiseptic dries
• C. Gently wipe the puncture site until a large droplet of blood forms
• D. Hold the finger below the heart level to puncture

Correct answer: B

Rationale: The correct instruction is to puncture the site after cleansing and before the antiseptic dries. This sequence helps ensure proper blood collection without introducing contaminants. Choice A is incorrect because wearing sterile gloves is not necessary for capillary blood glucose testing. Choice C is incorrect as wiping the puncture site can introduce contaminants and alter the blood sample. Choice D is incorrect as holding the finger below the heart level is not required for a capillary blood glucose test.

2. A healthcare professional is preparing to assess a patient for orthostatic hypotension. Which piece of equipment will the professional obtain to assess for this condition?

• A. Thermometer
• B. Elastic stockings
• C. Blood pressure cuff
• D. Sequential compression devices

Correct answer: C

Rationale: To assess for orthostatic hypotension, a healthcare professional needs to obtain a blood pressure cuff. Orthostatic hypotension is defined as a drop in blood pressure greater than 20 mm Hg in systolic pressure or 10 mm Hg in diastolic pressure when moving from lying down to a standing position. A thermometer (Choice A) is used to measure body temperature and is not directly related to assessing orthostatic hypotension. Elastic stockings (Choice B) are used for preventing deep vein thrombosis and improving circulation in the lower extremities, not for assessing orthostatic hypotension. Sequential compression devices (Choice D) are mechanical pumps that are used to prevent deep vein thrombosis and are not specifically used for assessing orthostatic hypotension.

3. A client is to receive 10 mEq of KCl diluted in 250 ml of normal saline over 4 hours. At what rate should the LPN/LVN set the client's intravenous infusion pump?

• A. 13 ml/hour
• B. 63 ml/hour
• C. 80 ml/hour
• D. 125 ml/hour

Correct answer: B

Rationale: To calculate the correct rate of infusion, divide the total volume by the total time: 250 ml / 4 hours = 62.5 ml/hour, which is rounded up to 63 ml/hour. This rate ensures the proper administration of the KCl over the 4-hour period. Choice A (13 ml/hour) is incorrect as it does not match the calculated rate. Choices C (80 ml/hour) and D (125 ml/hour) are also incorrect as they do not correspond to the calculated rate needed for the specified time frame.

4. A healthcare professional is preparing to administer enoxaparin subcutaneously to a client. Which of the following actions should the healthcare professional take?

• A. Administer the medication with the needle at a 45-degree angle.
• B. Administer the medication with the needle at a 90-degree angle.
• C. Inject the medication into the muscle.
• D. Pinch the skin before injecting.

Correct answer: B

Rationale: Enoxaparin is a medication that is administered subcutaneously, which means it should be injected into the fatty tissue layer beneath the skin. Administering enoxaparin at a 90-degree angle ensures proper absorption and reduces the risk of injecting the medication into muscle tissue, which could affect its effectiveness. Injecting the medication at a 45-degree angle may lead to improper absorption as it may not reach the subcutaneous tissue adequately. Injecting the medication into the muscle instead of subcutaneously can alter the absorption rate and therapeutic effects. Pinching the skin before injecting is not necessary for administering enoxaparin subcutaneously and may cause unnecessary discomfort to the client.

5. A nurse is caring for a postoperative client following knee arthroplasty who requires thigh-high compression sleeves. What should the nurse do?

• A. Make sure two fingers can fit under the sleeve.
• B. Apply the sleeve tightly to prevent blood clots.
• C. Ensure the sleeve is snug and comfortable.
• D. Check that the sleeve is loose enough to avoid constriction.

Correct answer: A

Rationale: The correct answer is to make sure two fingers can fit under the sleeve. This allows for proper circulation and ensures that the sleeve is not too tight, which can lead to complications such as impaired blood flow or tissue damage. Choice B is incorrect because applying the sleeve tightly can actually cause harm rather than prevent blood clots. Choice C is incorrect as snugness alone may not guarantee proper fit. Choice D is incorrect as a sleeve that is too loose can be ineffective in providing the necessary compression.
