Nursing Elites

1. Claudication is a well-known effect of peripheral vascular disease. Which of the following facts about claudication is correct? Select the one that doesn't apply:

• A. It results when oxygen demand is greater than oxygen supply.
• B. It is characterized by pain that often occurs during rest.
• C. It is a result of tissue hypoxia.
• D. It is characterized by cramping and weakness.

Correct answer: D

Rationale: Claudication is a symptom of peripheral vascular disease where there is an inadequate supply of oxygen to the muscles due to reduced blood flow. This mismatch between oxygen demand and supply leads to tissue hypoxia, resulting in cramping, weakness, and discomfort. Option D correctly states that claudication is characterized by cramping and weakness, making it the correct answer. Options A, B, and C are incorrect. Claudication occurs when oxygen demand exceeds supply, not the other way around as stated in Option A. Pain in claudication typically occurs with activity, not at rest as mentioned in Option B. While tissue hypoxia is a consequence of claudication, it is not the primary cause, making Option C incorrect.

2. A client in end-stage renal disease is receiving peritoneal dialysis at home. The nurse must educate the client about potential complications associated with this procedure. All of the following are complications associated with peritoneal dialysis EXCEPT:

• A. Hypotriglyceridemia
• B. Abdominal hernia
• C. Anorexia
• D. Peritonitis

Correct answer: A

Rationale: Peritoneal dialysis poses risks of various complications, including abdominal hernia, anorexia, peritonitis, and other issues. However, hypotriglyceridemia is not a common complication associated with peritoneal dialysis. The nurse should focus on educating the client about the risks of developing peritonitis, abdominal hernias, anorexia, low back pain, and abdominal bleeding. Monitoring triglyceride levels is essential for managing lipid disorders but is not directly linked to peritoneal dialysis complications.

3. During an assessment of a client with cardiomyopathy, the nurse finds that the systolic blood pressure has decreased from 145 to 110 mm Hg and the heart rate has risen from 72 to 96 beats per minute, and the client complains of periodic dizzy spells. The nurse instructs the client to:

• A. Increase fluids that are high in protein
• B. Restrict fluids
• C. Force fluids and reassess blood pressure
• D. Limit fluids to non-caffeine beverages

Correct answer: D

Rationale: In this scenario, the client with cardiomyopathy is exhibiting signs of orthostatic hypotension, which is characterized by a significant drop in systolic blood pressure (>15 mm Hg) and an increase in heart rate (>15%), along with dizziness. These symptoms suggest volume depletion, inadequate vasoconstrictor mechanisms, and autonomic insufficiency. The appropriate nursing intervention in this case is to force fluids and reassess blood pressure to address the underlying issue of volume depletion and improve hemodynamic stability. Choices A, B, and D are incorrect because increasing fluids high in protein, restricting fluids, or limiting fluids to non-caffeine beverages are not appropriate actions for a client experiencing orthostatic hypotension and signs of volume depletion.

4. After an unimmunized individual is exposed to hepatitis B through a needle-stick injury, which actions will the nurse plan to take (select one that does not apply)?

• A. Administer hepatitis B vaccine.
• B. Test for antibodies to hepatitis B.
• C. Teach about alpha-interferon therapy.
• D. Give hepatitis B immune globulin.

Correct answer: C

Rationale: In the case of exposure to hepatitis B, the nurse should plan to administer hepatitis B vaccine to provide active immunity. Testing for antibodies to hepatitis B is essential to determine the individual's immune status. Giving hepatitis B immune globulin is necessary for passive immunity in cases of exposure. However, teaching about alpha-interferon therapy is not part of the standard management for hepatitis B exposure. Interferon therapy and oral antivirals are typically used in the treatment of chronic hepatitis B infections, not for prophylaxis after exposure.

5. A client using an intraaural hearing aid experiences whistling after placement. What is the nurse's next action?

• A. Try to reposition the hearing aid
• B. Change the batteries
• C. Remove the device and have it cleaned
• D. Notify the physician that the hearing aid is not working

Correct answer: A

Rationale: An intraaural hearing aid, also known as an in-the-ear hearing aid, is placed in the ear canal. Whistling after placement indicates improper positioning of the device. The correct action for the nurse is to try repositioning the hearing aid to eliminate the whistling. Changing the batteries is not necessary for addressing whistling. Removing the device to clean it is not the immediate action needed for whistling. Notifying the physician is premature without attempting to reposition the hearing aid first.
