A nurse is monitoring the laboratory values of a client who is receiving heparin. Which of the following values should the nurse report to the provider?
PT 11 seconds
APTT 50 seconds
Hematocrit 456
Platelets 300,000/mm²
The Correct Answer is C
A.PT (Prothrombin Time) 11 seconds: The prothrombin time measures the extrinsic pathway of the coagulation cascade. A PT of 11 seconds is within the normal range, and it indicates that the extrinsic clotting pathway is functioning appropriately. There is no need to report this value.
B. APTT (Activated Partial Thromboplastin Time) 50 seconds: The APTT measures the intrinsic pathway of the coagulation cascade. A value of 50 seconds is prolonged and may suggest that the client is receiving an effective anticoagulant dose. However, the APTT target range can vary based on the specific therapeutic goal and the heparin protocol in use. It's essential to follow the healthcare provider's guidance on the target APTT range.
C. Hematocrit 456: The normal range for hematocrit is usually expressed as a percentage. A value of 456 is outside the normal range and likely represents an error or a misinterpretation. The nurse should verify this value, as an extremely high hematocrit could be indicative of an issue such as dehydration or an analytical error.
D. Platelets 300,000/mm²: A platelet count of 300,000/mm² is within the normal range. There is no need to report this value as it suggests a normal platelet count.

Correct Answer is A
Explanation
A. Rotate the application site every week (Correct Answer): This is the correct advice. Rotating the application site helps prevent skin irritation and enhances absorption. It's common practice to apply the patch to a different, clean, and hairless area of the skin each time it is changed.
B. The transdermal patch releases nicotine rapidly into the bloodstream: This statement is incorrect. The transdermal nicotine patch is designed to release nicotine gradually over an extended period. It provides a steady, controlled release of nicotine to help manage withdrawal symptoms and cravings.
C. Leave the patch in place for 8 hr each day: The specific duration for wearing a nicotine patch can vary depending on the product. However, it's generally recommended to wear the patch for 16 to 24 hours, depending on the product's instructions. Leaving it on for 8 hours only may not provide adequate coverage for the entire day.
D. The transdermal patch can cause insomnia: While insomnia is a potential side effect of nicotine replacement therapy, including the patch, it is not a universal experience for everyone. Insomnia is more likely to occur if the patch is worn continuously, including during the night. Following proper usage guidelines, such as removing the patch before bedtime, can help minimize this side effect.
Correct Answer is D
Explanation
A. I take metformin for my diabetes:
This statement indicates that the client is aware of taking metformin for diabetes. It is relevant information but doesn't raise immediate concerns about the interaction with lovastatin.
B. "I should avoid drinking grapefruit juice:"
This is a correct statement. Grapefruit juice can interact with lovastatin, potentially increasing the risk of side effects. Advising the client to avoid grapefruit juice is a proper precaution when taking lovastatin.
C. I am trying to decrease my dietary fat intake:
This statement indicates a positive lifestyle change that aligns with the goal of using lovastatin to lower cholesterol. It is a positive and relevant statement.
D. "I was just diagnosed with hepatitis B:"
This is the correct answer. Lovastatin is metabolized by the liver, and liver function is an important consideration. The nurse should assess the severity of hepatitis B, the client's liver function, and whether lovastatin is contraindicated or requires dose adjustment based on the hepatic impairment.
