Nursing Elites

1. A client with a history of atrial fibrillation is prescribed warfarin. What is the nurse's priority teaching?

• A. Avoid eating foods high in potassium.
• B. Avoid foods high in vitamin K.
• C. Take the medication on an empty stomach.
• D. Take the medication at bedtime for best results.

Correct answer: B

Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Warfarin is an anticoagulant medication that works by interfering with vitamin K-dependent clotting factors. Therefore, consuming foods high in vitamin K can affect the medication's effectiveness. Choices A, C, and D are incorrect because: A) Warfarin is not affected by foods high in potassium; C) Warfarin should be taken with food to minimize gastrointestinal side effects; D) There is no specific requirement for taking warfarin at bedtime for best results.

2. When taking a health history, which information collected by the nurse correlates most directly to a diagnosis of chronic peripheral arterial insufficiency?

• A. Reports of leg cramping at rest
• B. Family history of heart disease
• C. Current use of beta-blockers
• D. History of intermittent claudication

Correct answer: D

Rationale: Corrected Rationale: Intermittent claudication, or pain in the legs while walking that is relieved by rest, is a classic symptom of peripheral arterial insufficiency. Other factors such as a family history or medication use may contribute to cardiovascular health, but claudication is the most specific indicator. Leg cramping at rest is more indicative of conditions like peripheral neuropathy or deep vein thrombosis. Family history of heart disease and current use of beta-blockers are relevant to overall cardiovascular health, but they are not as directly related to chronic peripheral arterial insufficiency as intermittent claudication.

3. During an initial assessment, a healthcare provider notes that a client has elevated blood pressure. Which of the following findings is considered a major risk factor for coronary artery disease?

• A. Elevated HDL cholesterol
• B. Low LDL cholesterol
• C. Elevated blood pressure
• D. Low triglyceride levels

Correct answer: C

Rationale: Elevated blood pressure is a significant risk factor for coronary artery disease because it increases the strain on the arteries, leading to potential damage and a higher risk of developing coronary artery disease. Elevated HDL cholesterol (Choice A) is actually considered beneficial as it helps reduce the risk of heart disease. Low LDL cholesterol (Choice B) is also beneficial as high levels of LDL are associated with an increased risk of coronary artery disease. Low triglyceride levels (Choice D) are not typically considered a major risk factor for coronary artery disease.

4. A 60-year-old female client with a positive family history of ovarian cancer has developed an abdominal mass and is being evaluated for possible ovarian cancer. Her Papanicolau (Pap) smear results are negative. What information should the nurse include in the client’s teaching plan?

• A. Pap smear is sufficient to detect ovarian cancer
• B. Surgery is unnecessary based on negative Pap smear
• C. Further evaluation involving surgery may be needed
• D. No further tests are needed

Correct answer: C

Rationale: A negative Pap smear does not rule out ovarian cancer, which often requires more comprehensive evaluation, including imaging studies or surgery. The client should be informed that the Pap smear primarily detects cervical cancer, not ovarian cancer. Therefore, further evaluation involving imaging studies or surgery may be necessary to determine the presence of ovarian cancer. Choice A is incorrect because a Pap smear is not sufficient to detect ovarian cancer. Choice B is incorrect because surgery may be necessary for further evaluation if ovarian cancer is suspected. Choice D is incorrect because further tests are needed to confirm or rule out ovarian cancer.

5. The nurse is teaching a client with asthma to use a peak expiratory flow rate (PEFR) meter to manage asthma at home. The nurse knows the client understands the proper use of the meter when the client:

• A. Inhales as rapidly as possible when using the meter
• B. Records the highest of three readings
• C. Uses the meter after taking a bronchodilator
• D. Blows out forcefully into the meter after taking a deep breath

Correct answer: B

Rationale: The correct answer is B: 'Records the highest of three readings.' When using a peak expiratory flow rate (PEFR) meter, the client should record the highest of three readings to ensure an accurate measurement of their peak expiratory flow rate. Inhaling rapidly, using the meter after taking a bronchodilator, or blowing out forcefully into the meter after a deep breath are not correct techniques for using a PEFR meter and may lead to inaccurate results.
