A nurse is assessing a client who is postoperative following abdominal surgery and has an indwelling urinary catheter that is draining dark yellow urine at 25 mL/hr.
Which of the following interventions should the nurse anticipate?
Administer a fluid bolus
Initiate continuous bladder irrigation
Obtain a urine specimen for culture and sensitivity
Clamp the catheter tubing for 30 min
The Correct Answer is A
The correct answer is choice A, administer a fluid bolus.
Choice A rationale:
Administering a fluid bolus is appropriate when a client’s urine output is low, which in this case is less than the minimum expected output of 30 mL/hr. The dark yellow color of the urine also suggests dehydration or concentrated urine, which can be addressed with increased fluid intake.
Choice B rationale:
Initiating continuous bladder irrigation is typically done to clear the urinary tract of blood clots or debris following urologic surgery, not for low urine output or dark urine. Therefore, this intervention is not indicated based on the given scenario.
Choice C rationale:
Obtaining a urine specimen for culture and sensitivity is an action taken when there is a suspicion of a urinary tract infection. The scenario does not provide evidence of infection, such as fever or cloudy urine with a strong odor, so this would not be the first intervention to anticipate.
Choice D rationale:
Clamping the catheter tubing is done in preparation for catheter removal or to assess if the client can void without the catheter. It is not an appropriate intervention for low urine output or dark urine and could potentially cause bladder distention or discomfort.

Correct Answer is B
Explanation
Choice A reason
Act as a spokesperson to provide information to the media in inappropriate. During a disaster, the nurse manager or designated hospital spokesperson usually handles communication with the media. The unit nurse's primary focus is on patient care and ensuring the safety and well-being of the clients on their unit.
Choice B reason
Recommending to the provider a list of clients for early discharge is the action that should be taken by the nurse. During a disaster, the responsibility of the unit nurse includes recommending to the healthcare provider a list of clients who may be considered for early discharge. This decision is based on the nurse's assessment of the clients' conditions and the need to create additional capacity for incoming patients who require urgent medical attention.
Choice C reason:
Determining the need for additional providers is inappropriate. The determination of the need for additional providers during a disaster is usually made at a higher level, such as by the nursing supervisor, nurse manager, or hospital administration. The unit nurse may collaborate with the nursing leadership to assess staffing needs and provide input, but the final decision is typically made at a higher level.
Choice D reason
Deciding which clients should be transported for a higher level of care is not the responsibility of the nurse. Decisions about transferring clients for a higher level of care during a disaster are usually made collaboratively among the healthcare team, including the healthcare providers and nursing leadership. The unit nurse may provide valuable input about the clients' conditions, but the decision is not solely the responsibility of the unit nurse.
Correct Answer is A
Explanation
The correct answer is choice A. INR.
Warfarin is a vitamin K antagonist that inhibits the synthesis of factors II, VII, IX, and X in the liver.
These factors are part of the extrinsic and common pathways of coagulation, which are measured by the prothrombin time (PT) and the international normalized ratio (INR).
The INR is a standardized way of reporting the PT that accounts for the variability of different reagents and instruments.
The INR is used to monitor the therapeutic effect of warfarin and to adjust the dose accordingly.
The target INR range depends on the indication for warfarin, but it is usually between 2 and 3 for most conditions.
Choice B is wrong because fibrinogen level is not affected by warfarin.
Fibrinogen is a precursor of fibrin, which forms the final step of the coagulation cascade.
Fibrinogen level can be decreased in conditions such as disseminated intravascular coagulation (DIC), liver disease, or severe bleeding. Choice C is wrong because aPTT is not affected by warfarin.
aPTT measures the intrinsic and common pathways of coagulation, which are mainly dependent on factors VIII, IX, XI, and XII.
These factors are not inhibited by warfarin.
aPTT is used to monitor the effect of heparin, a direct antithrombin agent that inhibits thrombin and factor Xa.
Choice D is wrong because platelet count is not affected by warfarin.
Platelets are cell fragments that adhere to damaged blood vessels and form aggregates to initiate hemostasis.
Platelet count can be decreased in conditions such as immune thrombocytopenia (ITP), heparin-induced thrombocytopenia (HIT), or bone marrow suppression.
Normal ranges:
- INR: 0.8-1.2
- Fibrinogen: 200-400 mg/dL
- aPTT: 25-35 seconds
- Platelet count: 150-450 x 10^9/L References:
