A healthcare professional is caring for four clients on intravenous heparin therapy. Which lab value possibly indicates a serious side effect has occurred?

Correct Answer: B

Rationale: The correct answer is B: Platelet count: 82,000/µL. A low platelet count (thrombocytopenia) is a serious side effect of heparin therapy, as it can lead to bleeding complications. Platelets are essential for normal blood clotting. Hemoglobin, RBC count, and WBC count are not directly affected by heparin therapy and do not indicate a serious side effect.

Correct Answer: A

Rationale: The correct answer is A: Ask if the client eats grapefruit. Atorvastatin can interact with grapefruit juice, leading to increased drug levels and potential toxicity. The elevated BUN and creatinine levels suggest possible kidney impairment, which could be exacerbated by the drug interaction. Assessing for grapefruit consumption allows the nurse to address this potential risk factor. B: Assessing for dehydration would not directly address the potential drug interaction with grapefruit. C: Hospital admission is not necessary based solely on the information provided; this would be an extreme action without further assessment. D: Obtaining a random urinalysis would not provide relevant information related to the potential drug interaction with grapefruit.

Correct Answer: B

Rationale: Step-by-step rationale: 1. Choice B is correct because it educates the client that hypertension often presents without symptoms. 2. Lack of symptoms does not mean the condition is not serious. 3. This response promotes understanding and adherence to medication. 4. Choices A, C, and D are incorrect as they do not address the main issue of hypertension being asymptomatic.

Correct Answer: C

Rationale: The correct answer is C: It is hypertension with no specific cause. Rationale: 1. Essential hypertension is also known as primary or idiopathic hypertension. 2. It is the most common type of hypertension, accounting for about 90-95% of cases. 3. The exact cause of essential hypertension is unknown, but it is believed to be due to a combination of genetic, environmental, and lifestyle factors. 4. Choices A, B, and D are incorrect because essential hypertension is not caused by another disease, does not necessarily require treatment as essential means "fundamental," and is not specifically severe or life-threatening.

Correct Answer: A

Rationale: The correct answer is A: African American churches. This target audience is appropriate because African Americans have a higher prevalence of hypertension compared to other ethnic groups. By providing education and screening at African American churches, the nurse can reach a population that is at higher risk for hypertension. Churches are also community hubs where individuals gather regularly, making it an effective platform for health promotion. Choice B: Asian American groceries is incorrect as it does not specifically target a population with a high prevalence of hypertension. Choice C: High school sports camps may not be an ideal target audience for hypertension education as the focus is typically on physical fitness rather than chronic disease management. Choice D: Women's health clinics may not reach the priority population of African Americans who have a higher prevalence of hypertension.
