A nurse is reporting a client's laboratory tests to the provider to obtain a prescription for the client's daily warfarin. Which of the following laboratory tests should the nurse plan to report to obtain the prescription for the warfarin?
INR
Fibrinogen level
aPTT
Platelet count
The Correct Answer is A
A. Correct. The International Normalized Ratio (INR) is used to monitor the effectiveness of warfarin therapy, which is commonly prescribed to prevent blood clotting. The INR provides information about the client's prothrombin time (PT) in relation to a standardized value.
B. Fibrinogen level measures clotting potential but is not directly related to warfarin therapy monitoring.
C. Activated Partial Thromboplastin Time (aPTT) is used to monitor other anticoagulants like heparin, not warfarin.
D. Platelet count measures the number of platelets in the blood and is not specifically related to warfarin therapy monitoring.

Correct Answer is D
Explanation
Choice A reason:
"I try to respond to the baby quickly so she doesn't cry very long." This statement is incorrect because it indicates the parent's sensitivity to the baby's needs and responsiveness to the baby's cues, which are positive signs of appropriate caregiving.
Choice B reason:
"I have several friends who come by to help out with the baby." This statement is incorrect because having a support system in the form of friends who help with the baby is a positive factor that can reduce stress and promote a healthy postpartum period.
Choice C reason:
"I want to meet other parents to see if they are going through the same things." This statement is incorrect because seeking social support and connecting with other parents can be beneficial in reducing feelings of isolation and stress during the postpartum period.
Choice D reason:
"I think the baby should be sleeping through the night by now is the correct statement "I think the baby should be sleeping through the night by now," as a manifestation of increased risk for child abuse. This statement may indicate unrealistic expectations or frustration from the parent regarding the baby's sleep patterns.
It is common for newborns to wake frequently during the night for feeding and care, and their sleep patterns can vary significantly in the early weeks and months of life. Unrealistic expectations or frustration about the baby's sleep habits can contribute to increased stress for the parent, which might increase the risk of child abuse or neglect.
Correct Answer is ["A","C","E","G","H"]
Explanation
The correct answer is:Choices c, e, g, h, and a.
Choice A rationale (Current medications): The client is taking Ibuprofen 800 mg three times daily as needed for arthritis pain.Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that can cause gastrointestinal irritation, ulcers, and bleeding, especially when used at high doses or for a prolonged period12. Given the client’s symptoms of abdominal pain and a history of dark, tarry stool, the medication could be contributing to these symptoms and warrants further investigation.
Choice B rationale (Temperature): The client’s temperature is 37.5° C (99.5° F), which is within the normal range34. Therefore, it does not require immediate follow-up.
Choice C rationale (Hemoglobin and hematocrit): The client’s hemoglobin level is 9.1 g/dL, which is lower than the normal range of about 13.0 to 17.5 g/dL for adult males and 12.0 to 15.5 g/dL for adult females56.The client’s hematocrit is 27%, which is also lower than the normal range of about 38.3% to 48.6% for adult males and 35.5% to 44.9% for adult females7.Low hemoglobin and hematocrit levels can indicate anemia, which could explain the client’s reported fatigue and pale mucous membranes87.
Choice D rationale (WBC count): The client’s WBC count is 6,700/mm3, which falls within the normal range of about 4,500 to 11,000 WBCs per microliter910. Therefore, it does not require immediate follow-up.
Choice E rationale (Blood pressure): The client’s blood pressure is 90/50 mm Hg, which is lower than the normal range11. Low blood pressure can cause symptoms such as dizziness, fainting, or blurred vision and requires immediate follow-up.
Choice F rationale (Respiratory rate): The client’s respiratory rate is 18 breaths per minute, which is within the normal range for adults of about 12 to 20 breaths per minute412. Therefore, it does not require immediate follow-up.
Choice G rationale (Stool results): The client’s stool tested positive for blood (Hemoccult positive), which could indicate gastrointestinal bleeding13. This finding, combined with the client’s reported abdominal pain and history of dark, tarry stool, requires immediate follow-up.
Choice H rationale (Heart rate): The client’s heart rate is 118 beats per minute, which is higher than the normal range for adults of about 60 to 100 beats per minute14.A high heart rate, or tachycardia, can be caused by factors such as stress, anxiety, physical exertion, dehydration, and certain medical conditions14. Given the client’s reported symptoms and medical history, this finding warrants immediate follow-up.
