Nursing Elites

1. A healthcare professional is preparing to administer heparin 8,000 units subcutaneously every eight hrs. The amount available is heparin injection 10,000 units/mL. How many milliliters should the healthcare professional administer per dose?

• A. 0.7 mL
• B. 0.8 mL
• C. 1.0 mL
• D. 1.2 mL

Correct answer: B

Rationale: Calculation: 8000 units / 10,000 units per mL = 0.8 mL. To correctly administer the prescribed dose of 8000 units, the healthcare professional should draw up 0.8 mL from the 10,000 units/mL vial. Options A, C, and D are incorrect as they do not accurately reflect the calculation based on the available concentration of heparin.

2. While providing education about the use of lorazepam, which of the following should be included?

• A. It can cause dependency
• B. It can be taken with alcohol
• C. It has no side effects
• D. It is a stimulant

Correct answer: A

Rationale: The correct answer is A: 'It can cause dependency.' Lorazepam is a benzodiazepine known to cause dependency, so it is crucial for clients to be informed about this potential risk. Choice B is incorrect as combining lorazepam with alcohol can lead to increased sedation and other adverse effects. Choice C is incorrect because lorazepam, like any medication, can have side effects such as drowsiness, dizziness, or confusion. Choice D is also incorrect as lorazepam is a sedative-hypnotic medication, not a stimulant.

3. A nurse is teaching a client about using a continuous positive airway pressure (CPAP) device to treat obstructive sleep apnea. Which of the following information should the nurse include in the teaching?

• A. It delivers a preset amount of inspiratory pressure at the beginning of each breath
• B. It has a continuous adjustment feature that changes the airway pressure throughout the cycle
• C. It delivers a preset amount of airway pressure throughout the breathing cycle
• D. It delivers positive pressure at the end of each breath

Correct answer: C

Rationale: The correct information that the nurse should include in the teaching about a CPAP device is that it delivers a preset amount of airway pressure throughout the breathing cycle. This consistent positive airway pressure helps keep the airway open during both inspiration and expiration. Choice A is incorrect as CPAP does not deliver pressure only at the beginning of each breath. Choice B is incorrect because CPAP provides a constant level of pressure without continuous adjustments throughout the cycle. Choice D is incorrect as CPAP does not provide positive pressure at the end of each breath; instead, it maintains a continuous positive pressure.

4. A nurse is assessing a client who has a blood glucose level of 250 mg/dL. Which of the following clinical manifestations is associated with this finding?

• A. Confusion
• B. Thirst
• C. Diaphoresis
• D. Shakiness

Correct answer: B

Rationale: Corrected Detailed Rationale: A blood glucose level of 250 mg/dL indicates hyperglycemia. Thirst (polydipsia) is a common clinical manifestation associated with hyperglycemia. The body tries to compensate for the high blood sugar by increasing fluid intake. Confusion (choice A) is more commonly associated with hypoglycemia, not hyperglycemia. Diaphoresis (choice C) and shakiness (choice D) are typical manifestations of hypoglycemia, not hyperglycemia. Therefore, the correct answer is increased thirst (polydipsia) in response to the elevated blood glucose level.

5. A client has been prescribed metformin. What should be included in the teaching?

• A. It can cause weight gain
• B. Take it with food
• C. It is an insulin
• D. Monitor for hyperglycemia

Correct answer: B

Rationale: The correct answer is to take metformin with food. This is important to minimize gastrointestinal side effects and improve absorption. Choice A is incorrect as metformin is not typically associated with weight gain. Choice C is wrong as metformin is not an insulin but a medication that helps control blood sugar levels. Choice D is also incorrect as metformin is not known to cause hyperglycemia.
