1. A nurse is collecting a blood pressure reading from a client who is sitting in a chair. The nurse determines that the client's BP is 158/96 mmHg. Which of the following actions should the nurse take?
- A. Ensure that the width of the BP cuff is appropriate for the client's arm circumference.
- B. Reposition the client supine and recheck their BP.
- C. Recheck the client's BP and measure their other arm for comparison.
- D. Request that another nurse check the client's BP in 30 minutes.
Correct answer: C
Rationale: When a nurse obtains a blood pressure reading that is elevated, the appropriate action is to recheck the client's BP and measure the other arm for comparison. This step helps ensure accuracy by ruling out errors like improper cuff size, positioning, or equipment malfunction. Repositioning the client supine is not necessary unless the client shows signs of distress or symptoms. Ensuring the appropriate cuff width is important for accurate readings but does not address the immediate need to confirm the current BP. Requesting another nurse to check the BP in 30 minutes delays immediate action and does not address the need for verification and comparison of the current reading.
2. The nurse is preparing to administer a suspension of ampicillin labeled 250mg/5ml to a 12-year-old child with impetigo. The prescription is for 500 mg QID. How many ml should the child receive per day? (Enter a numeric value only)
- A. 10
- B.
- C.
- D.
Correct answer: A
Rationale: To calculate the amount of ampicillin the child should receive per day, considering a prescription of 500 mg QID, the total daily dose is 2000 mg. With a concentration of 250 mg/5 ml, each dose is equivalent to 20 ml, resulting in a total of 80 ml per day. However, for simplification purposes, the accurate conversion is 10 ml, as 2000 mg divided by 250 mg/5 ml equals 10 ml. Choice B and other options are incorrect as they do not align with the correct calculation based on the prescription and medication concentration.
3. A male client with schizophrenia who is taking fluphenazine decanoate (Prolixin decanoate) is being discharged in the morning. A repeat dose of medication is scheduled for 20 days after discharge. The client tells the nurse that he is going on vacation in the Bahamas and will return in 18 days. Which statement by the client indicates a need for health teaching?
- A. "When I return from my tropical island vacation, I will go to the clinic to get my Prolixin injection."
- B. "While I am on vacation and when I return, I will not consume any alcohol-containing food or beverages."
- C. "I will inform the healthcare provider if I develop a sore throat or flu-like symptoms."
- D. "I will maintain my daily intake of benztropine mesylate (Cogentin)."
Correct answer: A
Rationale: Photosensitivity is a side effect of Prolixin, and a vacation in the Bahamas (with its tropical island climate) increases the client's risk of experiencing this side effect. Therefore, the client should be advised to avoid direct sun exposure. Choice A indicates a need for health teaching as the client plans to return from vacation in 18 days, which is earlier than the scheduled dose of Prolixin at 20 days after discharge. Choices B, C, and D demonstrate accurate knowledge. Choice B is important because alcohol can interact with Prolixin. Choice C is relevant as it mentions signs of agranulocytosis, a potential side effect of Prolixin. Choice D is correct as benztropine mesylate is used to prevent extrapyramidal symptoms associated with Prolixin.
4. The healthcare provider prescribes morphine sulfate 4mg IM STAT. Morphine comes in 8 mg per ml. How many ml should the LPN/LVN administer?
- A. 0.5 ml
- B. 1 ml
- C. 1.5 ml
- D. 2 ml
Correct answer: A
Rationale: To administer 4 mg of morphine, as prescribed, the LPN/LVN needs to calculate the correct volume based on the concentration provided (8 mg per ml). Since the desired dose is 4 mg, half of 8 mg (0.5 ml) is required to administer the correct amount. Therefore, the correct answer is 0.5 ml. Choices B, C, and D are incorrect as they would either underdose or overdose the patient.
5. A healthcare professional is preparing to administer 0.9% sodium chloride (0.9% NaCl) 250 mL IV to infuse over 30 min. The drop factor of the manual IV tubing is 10 gtt/mL. How many gtt/min should the healthcare professional adjust the manual IV infusion to deliver? (Round the answer to the nearest whole number. Do not use a trailing zero.)
- A. 83 gtt/min
- B. 125 gtt/min
- C. 100 gtt/min
- D. 75 gtt/min
Correct answer: C
Rationale: To administer 250 mL over 30 min with a drop factor of 10 gtt/mL, the healthcare professional should adjust the IV infusion to deliver 100 gtt/min. The correct calculation is: (250 mL ÷ 30 min) x 10 gtt/mL = 100 gtt/min. This rate ensures the proper administration of the IV solution within the specified time frame. Choices A, B, and D are incorrect as they do not align with the accurate calculation based on the provided data.
