Nursing Elites

1. A nurse is reviewing the medical history of a client who has angina. Which of the following findings in the client's medical history should the nurse identify as a risk factor for angina?

• A. Hyperlipidemia.
• B. COPD.
• C. Seizure disorder.
• D. Hyponatremia.

Correct answer: A

Rationale: The correct answer is A: Hyperlipidemia. Hyperlipidemia, which is an elevated level of lipids (fats) in the blood, is a well-established risk factor for angina. High levels of lipids can lead to atherosclerosis, a condition where fatty deposits build up in the arteries, reducing blood flow to the heart muscle and increasing the risk of angina. Choice B, COPD (Chronic Obstructive Pulmonary Disease), is not directly linked to an increased risk of angina. COPD primarily affects the lungs and is not a known risk factor for angina. Choice C, Seizure disorder, and Choice D, Hyponatremia (low sodium levels), are also not typically associated with an increased risk of angina. While medical conditions like hypertension, diabetes, and smoking are other common risk factors for angina, hyperlipidemia is specifically known for its impact on blood vessels, making it a key risk factor to identify in a client's medical history.

2. A nurse is providing teaching to a client who is receiving radiation therapy for cancer of the larynx. Which of the following instructions should the nurse include?

• A. Apply heat to the neck to relieve pain.
• B. Use a soft-bristle toothbrush to prevent gum irritation.
• C. Rinse your mouth with an alcohol-free mouthwash twice daily.
• D. Wear loose-fitting clothing to protect your skin.

Correct answer: B

Rationale: The correct answer is to use a soft-bristle toothbrush to prevent gum irritation in clients undergoing radiation therapy for laryngeal cancer. Radiation therapy can cause oral mucositis and increase the risk of gum irritation, so using a soft-bristle toothbrush is recommended to minimize trauma to the gums and oral mucosa. Applying heat to the neck is contraindicated as it can exacerbate tissue damage caused by radiation. Rinsing the mouth with an alcohol-free mouthwash is preferred over an alcohol-based one to prevent drying and irritation of the oral mucosa. Wearing loose-fitting clothing is advised to prevent friction and irritation on the skin, rather than tight-fitting clothing that may cause pressure ulcers or skin breakdown.

3. A nurse is preparing to administer dopamine hydrochloride at 4 mcg/kg/min for a client weighing 80 kg. How many mL/hr should the nurse set the IV infusion to deliver?

• A. 6 mL/hr
• B. 8 mL/hr
• C. 12 mL/hr
• D. 16 mL/hr

Correct answer: A

Rationale: To calculate the correct rate, you first need to convert the weight to micrograms: 4 mcg/kg/min * 80 kg = 320 mcg/min. Then, convert micrograms to milligrams: 320 mcg/min / 1000 = 0.32 mg/min. Next, calculate how many milligrams per hour: 0.32 mg/min * 60 min/hr = 19.2 mg/hr. Finally, determine the mL/hr rate by using the concentration provided: 19.2 mg/hr / 800 mg in 250 mL = 6 mL/hr. Therefore, the correct answer is 6 mL/hr. Choice B, 8 mL/hr, is incorrect as it does not reflect the accurate calculation based on the weight and drug concentration. Choices C and D, 12 mL/hr and 16 mL/hr, are also incorrect as they do not align with the correct calculation of the infusion rate for dopamine hydrochloride based on the client's weight and the medication concentration.

4. Which of the following lab values should the nurse monitor for a patient receiving heparin therapy?

• A. Monitor platelet count
• B. Monitor PT/INR
• C. Monitor aPTT
• D. Monitor CBC

Correct answer: C

Rationale: The correct answer is to monitor aPTT for a patient receiving heparin therapy. The activated partial thromboplastin time (aPTT) is used to assess and adjust heparin dosage to ensure the patient is within the therapeutic range for anticoagulation. Monitoring the aPTT helps in preventing both clotting and bleeding complications. Platelet count (Choice A) is important to monitor for patients receiving antiplatelet therapy, not heparin. PT/INR (Choice B) is typically monitored for patients on warfarin therapy, not heparin. Monitoring the complete blood count (CBC) (Choice D) is essential for various conditions but is not specific to monitoring heparin therapy.

5. A nurse is teaching a client who has heart failure about managing fluid intake. Which of the following instructions should the nurse include?

• A. Drink 2 liters of water per day.
• B. You should restrict your fluid intake to 1 liter per day.
• C. You can drink as much fluid as you want throughout the day.
• D. Limit your fluid intake to 3 liters per day.

Correct answer: B

Rationale: The correct answer is B: "You should restrict your fluid intake to 1 liter per day." Clients with heart failure should limit their fluid intake to prevent fluid overload, which can worsen their condition. Choice A is incorrect because 2 liters of water per day may be excessive for someone with heart failure. Choice C is incorrect as unlimited fluid intake is not suitable for individuals with heart failure. Choice D is also incorrect as 3 liters per day may be too much fluid for a client with heart failure.
