1. A healthcare provider plans to administer Morphine IV to a postoperative client. Which of the following actions should the provider take?
- A. Monitor for seizures and confusion with repeated doses.
- B. Protect the client's skin from severe diarrhea associated with morphine.
- C. Withhold this medication if the respiratory rate is less than 12/min.
- D. Administer Morphine intermittently via IV bolus over 30 seconds or less.
Correct answer: C
Rationale: The correct action for the provider is to withhold morphine if the client's respiratory rate is 12/min or less. Respiratory depression is a serious side effect of morphine and other opioids. Withholding the medication and informing the healthcare provider is essential to prevent further respiratory compromise in the client. Choices A, B, and D are incorrect because monitoring for seizures and confusion, protecting the client's skin from severe diarrhea, and administering morphine via IV bolus over 30 seconds or less are not the primary actions to ensure client safety when administering morphine IV. Respiratory status is crucial due to the risk of respiratory depression associated with opioid administration.
2. A client has an infection and a prescription for gentamicin intermittent IV bolus every 8 hr. A peak and trough is required with the next dose. Which of the following actions should be taken to obtain an accurate gentamicin serum level?
- A. Draw a trough level immediately prior to administering the medication and a peak level 30 min after the dose.
- B. Draw a peak level 90 min prior to administering the medication and a trough level 90 min after the dose.
- C. Draw a trough level immediately prior to administering the medication and a peak level 30 min after the dose.
- D. Draw a peak level at 0900 and a trough level at 2100.
Correct answer: C
Rationale: To obtain an accurate gentamicin serum level, the trough should be drawn immediately before administering the medication, and the peak level should be drawn 30 minutes after the dose. This timing allows for the assessment of the lowest and highest drug concentrations in the bloodstream, ensuring therapeutic levels are achieved while minimizing the risk of toxicity. Choice A is correct as it follows this timing protocol. Choices B and D have incorrect timing for peak and trough levels, which would not provide an accurate representation of the drug's concentration in the bloodstream.
3. A client with cancer and a prescription for methotrexate PO reports bleeding gums while being assessed by a nurse in a provider's clinic. Which of the following actions should the nurse take?
- A. Explain to the client that this is an expected adverse effect.
- B. Check the value of the client's current platelet count.
- C. Instruct the client to use an electric toothbrush.
- D. Have the client make an appointment to see the dentist.
Correct answer: B
Rationale: The correct action for the nurse to take when a client on methotrexate reports bleeding gums is to check the client's current platelet count. Bleeding gums may indicate thrombocytopenia, a decreased platelet count which can be a severe side effect of methotrexate therapy. Monitoring the platelet count is crucial for early detection and management of this potentially life-threatening complication. Choice A is incorrect as bleeding gums in this context may not be an expected adverse effect of methotrexate. Choice C is irrelevant and does not address the potential underlying issue of thrombocytopenia. Choice D is not the primary action needed at this point; checking the platelet count is more urgent to assess the severity of the situation.
4. A healthcare professional is preparing to administer heparin 15,000 units subcutaneously every 12 hr. The amount available is heparin injection 20,000 units/mL. How many mL should the healthcare professional administer per dose?
- A. 0.8 mL
- B. 0.75 mL
- C. 0.5 mL
- D. 1 mL
Correct answer: A
Rationale: To calculate the volume to administer, use the formula: (Desired dose / Concentration) = Volume to administer. In this case, (15,000 units / 20,000 units/mL) = 0.75 mL, which is rounded up to 0.8 mL. Therefore, the healthcare professional should administer 0.8 mL per dose of heparin. Choice B (0.75 mL) is incorrect as it is the exact calculated volume but needs to be rounded up. Choices C (0.5 mL) and D (1 mL) are incorrect as they do not reflect the correct calculated volume for the desired dose of heparin.
5. A healthcare professional is preparing to administer a transfusion of a unit of packed red blood cells (PRBCs) for a client who has severe anemia. Which of the following interventions will prevent an acute hemolytic reaction?
- A. Ensure that the client has a patent IV line before obtaining the blood product from the refrigerator.
- B. Obtain help from another healthcare professional to confirm the correct client and blood product.
- C. Take a complete set of vital signs before beginning the transfusion and periodically during the transfusion.
- D. Stay with the client for the first 15 to 30 minutes of the transfusion.
Correct answer: B
Rationale: Obtaining help from another healthcare professional to confirm the correct client and blood product is crucial in preventing an acute hemolytic reaction during a blood transfusion. This reaction occurs due to ABO or Rh incompatibility. Verifying the correct client and blood product reduces the risk of administering the wrong blood type, which could lead to a life-threatening reaction. Checking for patency of the IV line (Choice A) is important but does not directly prevent an acute hemolytic reaction. Monitoring vital signs (Choice C) is essential for detecting transfusion reactions but does not prevent them. Staying with the client (Choice D) is important for early recognition of adverse reactions but does not address the root cause of preventing an acute hemolytic reaction.
