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. A nurse is preparing to administer a dose of enalapril. Which of the following should the nurse assess first?

• A. Heart rate
• B. Blood pressure
• C. Serum creatinine
• D. Potassium levels

Correct answer: B

Rationale: The correct answer is to assess blood pressure first. Enalapril is an ACE inhibitor commonly used to manage hypertension. It is crucial to evaluate the patient's blood pressure before administering enalapril to ensure it is within safe limits. Assessing other parameters like heart rate, serum creatinine, and potassium levels is also important but assessing blood pressure takes precedence due to the medication's mechanism of action and potential effects on blood pressure regulation.

3. A nurse is caring for a client who is taking warfarin. The nurse notes that the client has a new prescription for amoxicillin. Which of the following laboratory tests should the nurse monitor closely?

• A. Serum potassium
• B. Prothrombin time (PT)
• C. Serum sodium
• D. Blood glucose

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT). Amoxicillin can potentiate the effects of warfarin, increasing the risk of bleeding. Monitoring the prothrombin time (PT) is crucial in this situation to assess the client's clotting ability. Choices A, C, and D are incorrect because amoxicillin's interaction with warfarin does not directly impact serum potassium, serum sodium, or blood glucose levels.

4. A nurse is caring for a client with a chest tube following a thoracotomy. Which of the following findings requires intervention by the nurse?

• A. Tidaling with spontaneous respirations
• B. Drainage collection chamber is 1/3 full
• C. 1 cm of water present in the water seal chamber
• D. Suction chamber pressure of -20 cm H2O

Correct answer: C

Rationale: 1 cm of water in the water seal chamber is insufficient to ensure proper functioning of the chest tube. The water seal chamber typically requires a water level of 2 cm. Tidaling with spontaneous respirations (choice A) is an expected finding indicating proper functioning. Having the drainage collection chamber 1/3 full (choice B) is within the normal range. A suction chamber pressure of -20 cm H2O (choice D) is an appropriate level for chest tube drainage.

5. A nurse is caring for a client prescribed montelukast. Which of the following should the nurse include in teaching related to this medication?

• A. Advise the client to take the medication once daily at bedtime.
• B. This medication is for acute management of asthma.
• C. Avoid dairy products while taking this medication.
• D. If the client forgets to take the medication for a few days, he can double up on doses to catch up.

Correct answer: A

Rationale: The correct answer is to advise the client to take the medication once daily at bedtime. Montelukast, a leukotriene modifier, is used for long-term therapy of asthma in adults and children, as well as to prevent exercise-induced bronchospasm. It should be taken once daily in the evening for optimal effectiveness. Choice B is incorrect because montelukast is not for acute management but for long-term therapy. Choice C is incorrect as there is no need to avoid dairy products while taking montelukast. Choice D is incorrect and potentially harmful advice; clients should never double up on doses if they forget to take a medication.
