Extract:
Question 1 of 5
A nurse is reviewing the EKG strip of a client who has prolonged vomiting. Which of the following abnormalities on the client's EKG should the nurse interpret as a sign of hypokalemia?
Correct Answer: A
Rationale: The correct answer is A: Abnormally prominent U wave. In hypokalemia, low potassium levels can lead to U wave prominence on an EKG. The U wave becomes more visible and prominent due to delayed repolarization of the Purkinje fibers. This is a classic EKG finding in hypokalemia. Tachycardia (choice
B) is a non-specific finding and can be caused by various conditions. Flattened P wave (choice
C) is seen in hyperkalemia, not hypokalemia. Prolonged PR interval (choice
D) is more indicative of first-degree heart block or other conduction abnormalities, not specifically hypokalemia.
Question 2 of 5
A nurse is assessing a client who reports numbness and pain in his right palm, index finger, and middle finger. The client reports working with a keyboard most of the time while at work. The nurse suspects carpal tunnel syndrome. Which of the following tests should the nurse request that the client perform?
Correct Answer: A
Rationale: The correct answer is A: Hold the wrist at a 90-degree flexion. This test, known as the Phalen's test, is used to assess for carpal tunnel syndrome. By holding the wrist in a flexed position for about 60 seconds, the test can reproduce symptoms of numbness and tingling in the affected fingers. This occurs due to increased pressure on the median nerve, which is characteristic of carpal tunnel syndrome.
Choices B, C, and D are incorrect:
B: Performing a straight leg raise test is used to assess for sciatic nerve irritation in the lower back, not carpal tunnel syndrome.
C: Tapping the wrist for tenderness is not a specific test for carpal tunnel syndrome.
D: Holding the arm in an elevated position is not a recognized test for carpal tunnel syndrome and would not provide relevant information in this context.
Question 3 of 5
A nurse is teaching a class about preventive care to clients who are at risk for acquiring viral hepatitis. Which of the following information should the nurse include in the presentation?
Correct Answer: A
Rationale: The correct answer is A: Avoid foods prepared with tap water. Tap water in certain regions may be contaminated with hepatitis-causing viruses. Using bottled or purified water for drinking alone (choice
B) may not prevent exposure through food preparation. Limiting fried foods (choice
C) is unrelated to preventing viral hepatitis. While getting vaccinated for hepatitis C (choice
D) is important, it is not directly related to preventing exposure through contaminated tap water.
Therefore, the most effective preventive measure is to avoid foods prepared with tap water to reduce the risk of acquiring viral hepatitis.
Question 4 of 5
A nurse is providing teaching to a client about the manifestations of uterine prolapse. Which of the following statements by the client should indicate to the nurse a need for further teaching?
Correct Answer: B
Rationale: The correct answer is B. Feces present in the vagina is not a manifestation of uterine prolapse; it is a symptom of rectocele. The other choices are correct for uterine prolapse: A - Heavy lifting can worsen prolapse, C - Urinary incontinence is common due to pelvic floor weakness, D - Pelvic pressure during intercourse is a symptom.
Therefore, the client mentioning feces in the vagina indicates a need for further teaching on distinguishing between uterine prolapse and rectocele symptoms.
Question 5 of 5
A nurse is providing discharge teaching to a client who has a new arteriovenous fistula in the right forearm. Which of the following manifestations should the nurse include in the teaching as a possible indication of venous insufficiency?
Correct Answer: B
Rationale: The correct answer is B: Pallor and numbness distal to the fistula site. This is indicative of venous insufficiency in a client with an arteriovenous fistula. Venous insufficiency occurs when there is inadequate venous return to the heart, leading to decreased blood flow and oxygen delivery to the tissues. Pallor and numbness are signs of decreased blood flow, which can occur when the fistula is not functioning properly. Cold and numbness (choice
A) may indicate arterial insufficiency, not venous. Redness and warmth (choice
C) are signs of inflammation, not venous insufficiency. Pain in the fistula site (choice
D) may be due to other reasons like infection or nerve compression, not necessarily venous insufficiency.
