A nurse is reviewing laboratory findings for a client who is to receive a dose of enoxaparin. For which of the following laboratory values should the nurse withhold the dose and notify the provider?
BUN 22 mg/dL (10 to 20 mg/dL)
WBC count 15.000/mm3 (5,000 to 10,000/mm3)
Urine specific gravity 1.04 (1.005 to 1.03)
Platelets 80,000/mm3 (150,000 to 400.000/mm3)
The Correct Answer is D
A. BUN 22 mg/dL (10 to 20 mg/dL): A slightly elevated BUN indicates mild renal impairment or dehydration but does not typically require withholding enoxaparin. Monitoring renal function is important, but this value alone is not a contraindication for anticoagulation.
B. WBC count 15,000/mm3 (5,000 to 10,000/mm3): An elevated WBC suggests possible infection or inflammation. While it may warrant further assessment, it does not directly increase the risk of bleeding and is not a reason to withhold enoxaparin.
C. Urine specific gravity 1.04 (1.005 to 1.03): A high specific gravity may indicate dehydration but is not a contraindication for enoxaparin administration. The medication can be given with caution while monitoring renal function and fluid status.
D. Platelets 80,000/mm3 (150,000 to 400,000/mm3): Thrombocytopenia significantly increases the risk of bleeding while on enoxaparin, which is an anticoagulant. Withholding the dose and notifying the provider is essential to prevent hemorrhagic complications and ensure safe management of the client.

Correct Answer is A
Explanation
A. Perform bimanual fundal massage: Excessive vaginal bleeding postpartum often indicates uterine atony. Performing a bimanual fundal massage helps stimulate uterine contraction, which can reduce hemorrhage. This is a primary and immediate intervention in postpartum bleeding management.
B. Weigh perineal pads: Weighing pads helps quantify blood loss but does not actively stop hemorrhage. While important for assessment and documentation, it is not the first action when the client is actively bleeding.
C. Initiate oxygen at 2 L/min via nasal cannula: Administering oxygen may support tissue oxygenation but does not address the underlying cause of postpartum hemorrhage. Oxygen is supportive care and should not replace interventions to control bleeding.
D. Administer terbutaline: Terbutaline is a uterine relaxant used to treat preterm labor, which would worsen postpartum bleeding by inhibiting uterine contraction. It is contraindicated in cases of active postpartum hemorrhage.
Correct Answer is A
Explanation
A. A client who has depression and anxiety with an established plan of care: A medical-surgical nurse can safely care for a client with stable mental health conditions when a clear, established plan of care is in place. This client does not require constant psychiatric interventions, making it appropriate for assignment.
B. A client who is trying to engage in self-harm and does not understand why they cannot leave the facility: This client is high-risk and requires a nurse with specialized mental health training to implement safety measures and therapeutic interventions. Assigning this client to a medical-surgical nurse could compromise safety.
C. A client who is being discharged and needs information on substance abuse counseling: Discharge teaching and counseling for substance abuse require specialized knowledge and therapeutic communication skills typical of mental health nurses. A medical-surgical nurse may not have the expertise to provide adequate education and support.
D. A client who has been placed in restraints and requires documentation every 15 min: Clients in restraints require frequent monitoring, crisis intervention, and mental health expertise. This high-acuity situation is not appropriate for a nurse without psychiatric training.
