Correct Answer: B

Rationale: An INR of 1.2 is below the therapeutic range for a client on warfarin, indicating inadequate anticoagulation. Therefore, the client would require an increase in the dose of warfarin to achieve the desired therapeutic effect. Choices A, C, and D are not indicative of the need for a dose increase in warfarin therapy. PT of 28 seconds is within the therapeutic range, aPTT of 40 seconds is also within the normal range, and fibrinogen level of 350 mg/dL does not provide information about the anticoagulant effect of warfarin.

Correct Answer: C

Rationale: The correct answer is C. A serum potassium level of 3.2 mEq/L is below the normal range, indicating hypokalemia. Before administering potassium chloride, which is used to treat low potassium levels, the nurse should report this finding to the provider for further evaluation and potential adjustment of the treatment plan. Choices A, B, and D are within normal ranges and do not directly relate to the need for potassium chloride administration.

Correct Answer: C

Rationale: The correct action for the nurse to take when caring for a client receiving nitroprusside for severe hypertension is to limit light exposure to the IV infusion. Nitroprusside is light-sensitive, and exposure to light can lead to degradation of the medication, reducing its effectiveness. Administering oxygen (Choice A) may be necessary for some clients but is not directly related to the administration of nitroprusside. Monitoring blood pressure every 2 hours (Choice B) is a general nursing intervention for clients with hypertension but does not specifically address the administration of nitroprusside. Attaching an inline filter to the IV tubing (Choice D) is not necessary to address the specific concern of light exposure related to nitroprusside administration.

Correct Answer: A

Rationale: Corrected Rationale: Increased bilirubin levels are expected in clients with cirrhosis due to impaired liver function. Elevated bilirubin levels are commonly seen in cirrhosis as the liver's ability to process bilirubin is compromised. Decreased albumin levels and increased prothrombin time are also associated with cirrhosis, but the most specific finding related to liver dysfunction among the choices provided is increased bilirubin levels. Decreased serum glucose levels are not typically associated with cirrhosis.

Correct Answer: D

Rationale: Pale, cool skin is a common finding in clients with a hemoglobin level of 7 g/dL due to decreased oxygen carrying capacity. Bounding pulses (Choice A) are not typically associated with low hemoglobin levels. Elevated blood pressure (Choice B) is not a common finding in clients with anemia. While headache (Choice C) can occur with anemia, it is not a specific finding directly related to a hemoglobin level of 7 g/dL.
