1. While teaching a group of adults about health promotion activities, a nurse identifies a behavior that poses the most significant risk factor for the development of skin cancer. Which behavior should the nurse address?
- A. Consuming a high-fat diet
- B. Using tanning beds
- C. Smoking cigarettes
- D. Drinking alcohol
Correct answer: B
Rationale: Using tanning beds is the most significant risk factor for developing skin cancer. Ultraviolet (UV) radiation from tanning beds damages the skin and increases the risk of skin cancer. Consuming a high-fat diet, smoking cigarettes, and drinking alcohol are unhealthy behaviors but are not directly linked to the development of skin cancer like UV exposure from tanning beds.
2. A client is receiving a low dose of dopamine (Intropin) IV for the treatment of hypotension. Which indicator reflects that the medication is having the desired effect?
- A. Increased heart rate
- B. Increased urinary output
- C. Increased blood pressure
- D. Increased respiratory rate
Correct answer: C
Rationale: Increased blood pressure is the desired effect of administering dopamine (Intropin) to treat hypotension. Dopamine acts by stimulating adrenergic receptors, leading to vasoconstriction and increased cardiac output. This results in an elevation of blood pressure. Choices A, B, and D are incorrect as they do not directly reflect the therapeutic action of dopamine in treating hypotension. Increased heart rate may indicate the body compensating for low blood pressure, increased urinary output is more related to kidney function, and increased respiratory rate is often seen in response to respiratory issues, not the action of dopamine on hypotension.
3. The healthcare provider prescribes amoxicillin (Amoxil) 1.5 grams PO daily, in equally divided doses to be administered every 8 hours. The medication is available in a bottle labeled Amoxicillin (Amoxil) suspension 200 mg/5 ml. How many ml should the nurse administer every 8 hours?
- A. 10 ml
- B. 12.5 ml
- C. 15 ml
- D. 17.5 ml
Correct answer: B
Rationale: To calculate the correct dosage, first, determine the total daily dose: 1.5 grams = 1500 mg. Since the medication is 200 mg/5 ml, for 1500 mg, the nurse needs to administer 1500/200 = 7.5 times the 5 ml dose. Therefore, 7.5 x 5 ml = 37.5 ml total daily dose. To administer this every 8 hours, divide 37.5 ml by 3 (8 hours intervals in a day) to get 12.5 ml to be administered every 8 hours. Choice A, C, and D are incorrect as they do not reflect the correct calculation of the dose based on the prescription and the available concentration.
4. A male client is admitted to the mental health unit because he experiences panic attacks when driving on the freeway. To attempt to desensitize this fear, what action should the nurse encourage the client to implement?
- A. Watch training videos of people driving in various environments
- B. Begin visualizing himself driving each route to the freeway
- C. Take antianxiety medication two hours before driving on freeways
- D. Get in the car with a support person and drive on a freeway during rush hour
Correct answer: B
Rationale: Visualization techniques, such as visualizing himself driving each route to the freeway, are commonly used in desensitization therapy to help clients gradually overcome their fears. Watching videos of others driving or taking medication do not actively involve the client in facing their fear, which is essential in desensitization therapy. Getting in the car with a support person during rush hour may exacerbate the client's anxiety rather than help in desensitization.
5. The nurse is caring for a client who is receiving heparin therapy. Which laboratory value should the nurse monitor to determine the effectiveness of the therapy?
- A. Prothrombin time (PT)
- B. Partial thromboplastin time (PTT)
- C. International normalized ratio (INR)
- D. Activated partial thromboplastin time (aPTT)
Correct answer: C
Rationale: The correct answer is C, International Normalized Ratio (INR). While INR is commonly used to monitor the effectiveness of warfarin therapy, in the case of heparin therapy, the Partial Thromboplastin Time (PTT) is the preferred test. Choice A, Prothrombin Time (PT), measures the activity of the extrinsic pathway of coagulation and is not the best choice for monitoring heparin therapy. Choice D, Activated Partial Thromboplastin Time (aPTT), is similar to PTT and is used to monitor heparin therapy, but PTT is the more specific test. Therefore, monitoring PTT is crucial in determining the effectiveness and safety of heparin therapy.
