1. Which of the following lab values indicates a patient on warfarin is at a therapeutic level?

Correct answer: C

Rationale: An INR of 2.5 indicates a therapeutic level for a patient on warfarin. The INR (International Normalized Ratio) is the most accurate way to monitor and adjust warfarin doses. An INR of 1.1 (Choice A) is below the therapeutic range, indicating a need for an increased dose. PT (Prothrombin Time) of 12 seconds (Choice B) is not specific for warfarin therapy monitoring. Platelet count (Choice D) is not directly related to monitoring warfarin therapy.

2. A toddler is being admitted to the hospital after an Acetaminophen overdose. Which of the following medications should the nurse anticipate administering to this patient?

Correct answer: A

Rationale: In cases of Acetaminophen overdose, acetylcysteine is the antidote of choice. Acetylcysteine helps prevent liver damage by replenishing depleted glutathione levels, which is essential for detoxifying acetaminophen metabolites. Pegfilgrastim is a medication used to stimulate white blood cell production, Misoprostol is a medication for preventing stomach ulcers, and Naltrexone is used for treating opioid addiction and alcoholism, but none of these are indicated for Acetaminophen overdose.

3. Shamona, a pregnant mother in Flint, Michigan, is concerned about the drinking water, which shows high levels of lead. Shamona should know that high levels of prenatal lead exposure are related to __________.

Correct answer: C

Rationale: High levels of prenatal lead exposure are related to low birth weight and brain damage. Lead exposure during pregnancy can have harmful effects on the developing fetus, leading to complications such as decreased birth weight and potential long-term brain damage. Choices A, B, and D are incorrect because they do not directly correlate with the known effects of prenatal lead exposure. While lead exposure can indeed cause a variety of health issues, such as heart defects and urinary tract problems, the primary concerns related to prenatal exposure are low birth weight and brain damage.

4. A healthcare provider is assessing a child with acute lymphocytic leukemia. Which of the following findings is the priority for the healthcare provider to report?

Correct answer: B

Rationale: The priority finding to report for a child with acute lymphocytic leukemia is petechiae. Petechiae indicate a low platelet count, which increases the risk of bleeding. Therefore, the healthcare provider should promptly report petechiae to initiate appropriate interventions to prevent bleeding complications.

5. What is a good source of potassium and can be related to increased excretion?

Correct answer: C

Rationale: Broccoli is a good source of potassium and can contribute to increased excretion. While potassium itself is a mineral and increased excretion can be related to dietary intake, the specific relationship mentioned in the text is about broccoli being a good source of potassium and having a potential impact on excretion.
