1. A nurse is preparing to administer dopamine hydrochloride at 4 mcg/kg/min for a client weighing 80 kg. How many mL/hr should the nurse set the IV infusion to deliver?

• A. 6 mL/hr
• B. 8 mL/hr
• C. 12 mL/hr
• D. 16 mL/hr

Correct answer: A

Rationale: To calculate the correct rate, you first need to convert the weight to micrograms: 4 mcg/kg/min * 80 kg = 320 mcg/min. Then, convert micrograms to milligrams: 320 mcg/min / 1000 = 0.32 mg/min. Next, calculate how many milligrams per hour: 0.32 mg/min * 60 min/hr = 19.2 mg/hr. Finally, determine the mL/hr rate by using the concentration provided: 19.2 mg/hr / 800 mg in 250 mL = 6 mL/hr. Therefore, the correct answer is 6 mL/hr. Choice B, 8 mL/hr, is incorrect as it does not reflect the accurate calculation based on the weight and drug concentration. Choices C and D, 12 mL/hr and 16 mL/hr, are also incorrect as they do not align with the correct calculation of the infusion rate for dopamine hydrochloride based on the client's weight and the medication concentration.

2. How should a healthcare professional prepare a patient for a colonoscopy?

• A. Provide clear instructions on diet
• B. Explain the procedure in detail
• C. Ensure the patient has an empty stomach
• D. Give a bowel prep solution

Correct answer: D

Rationale: Giving a bowel prep solution is essential to clean out the colon thoroughly before a colonoscopy. This process is crucial as it helps to achieve a clear view of the colon during the procedure. Providing clear instructions on diet (Choice A) and ensuring the patient has an empty stomach (Choice C) are important steps in the preparation process but may not be sufficient on their own to adequately cleanse the colon. Explaining the procedure in detail (Choice B) is helpful for patient education but does not directly contribute to the physical preparation required for a successful colonoscopy.

3. A charge nurse is teaching a group of newly licensed nurses about the correct use of restraints. Which of the following should the nurse include in the teaching?

• A. Placing a belt restraint on a school-age child who has seizures.
• B. Securing wrist restraints to the bed rails for an adolescent.
• C. Applying elbow immobilizers to an infant receiving cleft lip injury.
• D. Keeping the side rails of a toddler's crib elevated.

Correct answer: D

Rationale: The correct answer is D. Keeping the side rails of a toddler's crib elevated is an appropriate use of restraints to prevent the child from falling, which is an essential safety measure. Placing a belt restraint on a school-age child with seizures (choice A) is not recommended as it can be dangerous during a seizure. Securing wrist restraints to the bed rails for an adolescent (choice B) may cause harm and should not be done routinely. Applying elbow immobilizers to an infant receiving a cleft lip injury (choice C) is not a standard practice for managing this condition and would not be appropriate.

4. A nurse is preparing to administer a dose of vancomycin IV to a client who has a methicillin-resistant Staphylococcus aureus (MRSA) infection. Which of the following actions should the nurse take?

• A. Administer the medication over 15 minutes.
• B. Monitor the client's urine output every 8 hours.
• C. Check the client's creatinine level before administering the medication.
• D. Assess the client for a history of allergies to antibiotics.

Correct answer: C

Rationale: The correct action for the nurse to take is to check the client's creatinine level before administering vancomycin. Vancomycin is known to be nephrotoxic, so assessing the client's renal function before administering the medication is crucial to prevent further kidney damage. Administering the medication over 15 minutes (Choice A) is not the priority in this scenario as renal function assessment takes precedence. Monitoring urine output (Choice B) is important for assessing renal function but checking creatinine level directly provides more accurate information. Assessing for allergies to antibiotics (Choice D) is also important but not as essential as checking the creatinine level due to the nephrotoxic nature of vancomycin.

5. What is the appropriate action for a patient experiencing a severe allergic reaction?

• A. Administer epinephrine
• B. Administer antihistamines
• C. Administer corticosteroids
• D. Administer oxygen

Correct answer: A

Rationale: The correct answer is to administer epinephrine. Epinephrine is the first-line treatment for severe allergic reactions as it helps reverse the symptoms rapidly by constricting blood vessels, increasing heart rate, and opening airways. Antihistamines (Choice B) may help with mild allergic reactions but are not effective for severe cases. Corticosteroids (Choice C) are used to reduce inflammation and are typically not the first-line treatment for acute severe allergic reactions. Administering oxygen (Choice D) may be necessary to support breathing in severe cases, but epinephrine is the primary treatment to reverse the allergic reaction symptoms.
