A nurse is preparing to administer acetaminophen 10 mg/kg PO every 6 hr to a toddler who weighs 26.4 lb. Available is acetaminophen 80 mg/0.8 mL liquid. How many mL should the nurse administer with each dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

B. Maculopapular rash is a potential adverse effect of ceftriaxone. It is a type of skin rash characterized by flat, red areas (macules) and raised, bumpy areas (papules). If a client develops a rash while taking ceftriaxone, it should be reported to the healthcare provider for evaluation.

A. Constipation is not a common adverse effect of ceftriaxone. It is more commonly associated with other medications or medical conditions unrelated to ceftriaxone.
C. Pitting edema is not a common adverse effect of ceftriaxone. It may occur as a result of other medical conditions or medications, but it is not specifically associated with ceftriaxone.
D. Concentrated urine is not a common adverse effect of ceftriaxone.

D. The INR is the standard laboratory test used to monitor the effectiveness of warfarin therapy. Warfarin interferes with the synthesis of vitamin K-dependent clotting factors, primarily factors II, VII, IX, and X. The INR provides a standardized measure of coagulation status, allowing healthcare providers to adjust warfarin dosage to maintain therapeutic anticoagulation while minimizing the risk of bleeding or thrombosis.
A. Platelets are involved in the process of blood clotting, but checking platelet levels is not specific to monitoring warfarin therapy. Platelet count may be relevant in assessing overall coagulation status, but it is not the primary laboratory value monitored for warfarin therapy.
B. OPTT measures the time it takes for blood to clot after specific clotting factors are activated. While OPTT is used to monitor the effectiveness of heparin therapy, it is not routinely monitored for warfarin therapy. Warfarin primarily affects the extrinsic pathway of the coagulation cascade, and the international normalized ratio (INR) is the standard laboratory test used to monitor warfarin therapy.
C. White blood cell count assesses the number of white blood cells in the blood and is used to evaluate the immune system and detect infections. Monitoring white blood cell count is not specific to warfarin therapy and is not routinely checked prior to administering warfarin.
