1. A client with a history of rheumatoid arthritis is prescribed methotrexate. Which laboratory value should the nurse monitor closely?

A. Liver function tests
B. Complete blood count
C. Serum creatinine
D. Prothrombin time

Correct answer: C

Rationale: Serum creatinine should be closely monitored in a client receiving methotrexate, as the medication can cause nephrotoxicity. Monitoring serum creatinine levels helps assess kidney function and detect potential nephrotoxic effects of methotrexate. Liver function tests (Choice A) are important to monitor for hepatotoxicity caused by methotrexate. While methotrexate can cause bone marrow suppression, leading to anemia, leukopenia, and thrombocytopenia, monitoring a complete blood count (Choice B) is essential but not the priority in this case. Prothrombin time (Choice D) is not typically affected by methotrexate therapy and is not the primary laboratory value to monitor in this situation.

2. The healthcare provider prescribes carboprost tromethamine (Hemabate) 250 mcg IM for a multigravida postpartum client who is experiencing heavy, bright red vaginal bleeding. Prior to administering this medication, which intervention should the RN implement?

A. Give the prescribed antiemetic.
B. Administer IV fluids.
C. Prepare for possible blood transfusion.
D. Monitor vital signs every 5 minutes.

Correct answer: A

Rationale: The correct answer is A. Hemabate can cause severe nausea, vomiting, or diarrhea, so administering the prescribed antiemetic can help manage these side effects. Choice B is incorrect as there is no indication in the scenario to administer IV fluids. Choice C is not the priority at this stage as the client's condition does not necessitate an immediate blood transfusion. Choice D is unnecessary every 5 minutes; monitoring vital signs should be done but not at such a high frequency.

3. Following a gunshot wound to the abdomen, a young adult male had an emergency bowel resection and received multiple blood products while in the operating room. His current blood pressure is 78/52 mm Hg, he is being mechanically ventilated, and his oxygen saturation is 87%. His laboratory values include hemoglobin 7.0 g/dL, platelets 20,000/mm³, and white blood cells 1,500/mm³. Based on these assessment findings, which intervention should the nurse implement first?

A. Transfuse packed red blood cells.
B. Obtain blood and sputum cultures.
C. Infuse 1000 ml of normal saline.
D. Titrate oxygen to keep O2 saturation at 90%.

Correct answer: A

Rationale: The client is exhibiting signs of severe anemia and hypovolemic shock, indicated by low hemoglobin levels and hypotension. The first priority is to address the low hemoglobin by transfusing packed red blood cells to improve oxygen-carrying capacity and perfusion to vital organs. While obtaining blood and sputum cultures is important for identifying potential infections, infusing normal saline can help with volume expansion but does not address the primary issue of severe anemia. Titrating oxygen to maintain an oxygen saturation of 90% is crucial but should follow the administration of packed red blood cells to optimize oxygen delivery.

4. A client with a history of chronic kidney disease is scheduled for a renal biopsy. Which laboratory value should the nurse report to the healthcare provider before the procedure?

A. Serum creatinine of 1.8 mg/dl
B. Prothrombin time of 18 seconds
C. Hemoglobin of 9 g/dl
D. Platelet count of 90,000/mm3

Correct answer: D

Rationale: A platelet count of 90,000/mm3 is low and concerning for a client scheduled for a renal biopsy, as it increases the risk of bleeding. Thrombocytopenia, indicated by a low platelet count, can lead to impaired blood clotting, posing a significant risk of bleeding during or after the biopsy procedure. Elevated serum creatinine levels may be expected in chronic kidney disease but are not directly related to bleeding risk during a renal biopsy. Prothrombin time and hemoglobin levels are not as directly relevant to the bleeding risk associated with a renal biopsy as platelet count.

5. A client who had a gestational trophoblastic disease (GTD) evacuated 2 days ago is being monitored for choriocarcinoma. She lives in a rural area, and her husband takes the family car to work daily, leaving her without transportation during the day. What intervention is most important for the nurse to implement?

A. Teach the client about the use of a home pregnancy test.
B. Schedule a weekly home visit to draw hCG values.
C. Make a 5-week follow-up appointment with the healthcare provider.
D. Begin chemotherapy administration during the first home visit.

Correct answer: B

Rationale: Scheduling weekly home visits to monitor hCG levels is critical for early detection of choriocarcinoma, a potential complication of GTD. Choice A is incorrect because a home pregnancy test is not the appropriate method to monitor for choriocarcinoma. Choice C is less frequent than necessary for close monitoring. Choice D is incorrect as chemotherapy administration should be based on confirmed diagnosis and treatment plan, not initiated during the first home visit.
