Correct Answer: B

Rationale: A weight gain of 0.9 kg (2 lb) in 1 week is an indication of fluid retention, which is concerning in a client with preeclampsia. This can be a sign of worsening condition requiring immediate medical attention. High blood pressure (option A) is expected in preeclampsia, a urine output of 30 mL/hr (option C) is decreased but not as urgent as the weight gain in this scenario, and a respiratory rate of 16/min (option D) is within normal limits.

Correct Answer: B

Rationale: Clients with a low platelet count are at risk of bleeding and infection. Monitoring the client's temperature every 4 hours is crucial to detect early signs of infection, as they may not be able to mount a typical immune response due to their compromised platelet count. Administering aspirin (choice A) is contraindicated in clients with low platelet counts as it can further increase the risk of bleeding. Monitoring urine output (choice C) and checking for stool in a colostomy bag (choice D) are important aspects of care but are not the priority in a client with low platelet count.

Correct Answer: B

Rationale: The correct answer is B: International normalized ratio (INR). When a client is on warfarin therapy, the INR is monitored regularly to assess the anticoagulant effects of the medication. A therapeutic INR range for most indications is between 2.0 to 3.0. Choices A, C, and D are not typically used to monitor the effect of warfarin. Platelet count assesses the number of platelets in the blood, PT measures the clotting time of plasma, and PTT evaluates the intrinsic pathway of coagulation.

Correct Answer: D

Rationale: An irregularly shaped mole is a priority finding to report to the provider as it can be indicative of melanoma, a type of skin cancer. Melanoma is a serious condition that requires prompt evaluation and treatment. Raised nevus, macule, and vesicle are common skin findings that are typically benign and may not require immediate attention. Therefore, the irregularly shaped mole stands out as the priority due to its association with potential malignancy.

Correct Answer: A

Rationale: A heart rate of 78/min is within the normal range; however, postoperative patients require close monitoring for any signs of complications. While the heart rate is normal, other critical findings such as increased pain, excessive bleeding, or other concerning symptoms may need immediate attention. Choices B, C, and D all indicate normal postoperative vital signs and oxygen saturation levels, which do not raise immediate concerns requiring reporting to the provider.
