A nurse in a provider’s office performs a fecal occult blood test with a positive result on a client.
Which of the following clients may have a false positive result?
A. A client who has a venous stasis ulcer.
A client who has peripheral hematomas.
A client who underwent a barium swallow study.
A client who takes an iron supplement.
The Correct Answer is C
Correct answer: C
A. A client who has a venous stasis ulcer: This is less likely to cause a false positive result. While ulcers can bleed, the fecal occult blood test is designed to detect small amounts of blood in the stool, not necessarily blood from other sources like venous stasis ulcers.
B. A client who has peripheral hematomas: Peripheral hematomas are typically not related to the fecal occult blood test. They generally wouldn’t affect the results unless there was significant bleeding or if the hematomas were a result of an underlying bleeding disorder.
C. A client who underwent a barium swallow study: This is the most likely to cause a false positive result. Barium used in the study can sometimes appear as a false positive on the test due to its interference with the chemical reactions used to detect blood.
D. A client who takes an iron supplement: Iron supplements can actually cause a false negative result rather than a false positive because they may darken the stool and mask the presence of blood.

Correct Answer is A
Explanation
Aspiration is when food or liquid enters the airway and causes choking or infection. Speech therapists can teach clients exercises to strengthen the muscles involved in swallowing, as well as strategies to prevent aspiration, such as changing the position of the head or the texture of the food.
Choice B is wrong because respiratory therapists help clients with breathing problems, not swallowing problems.
They may provide oxygen therapy, chest physiotherapy, or mechanical ventilation.
Choice C is wrong because physical therapists help clients with mobility problems, not swallowing problems.
They may provide exercises, massage, or assistive devices to improve movement and function.
Choice D is wrong because occupational therapists help clients with daily living activities, not swallowing problems.
They may provide training, adaptive equipment, or environmental modifications to enhance independence and quality of life.
Dysphagia is a medical term for swallowing difficulties.
It can be caused by various conditions that affect the nerves or muscles involved in swallowing, such as stroke, head injury, Parkinson’s disease, or esophageal cancer.
Dysphagia can lead to complications such as malnutrition, dehydration, or aspiration pneumonia.
Correct Answer is C
Explanation
The correct answer is choice C. The client who says “I need to learn how to perform a dressing change on my leg” is indicating an acceptance of the limb loss and a readiness to learn self-care skills.
This is a positive sign of coping and adaptation after an amputation surgery.
Choice A is wrong because the client who says “I am going to have to find someone who can take care of my leg at home” is expressing dependency and denial of the limb loss.
The client needs to be encouraged to participate in self-care activities and rehabilitation.
Choice B is wrong because the client who says “I stay awake at night because I keep thinking about my leg” is experiencing phantom limb sensation, which is a common phenomenon after amputation.
The client may benefit from pain management, distraction techniques, and counseling.
Choice D is wrong because the client who says “I know my family means well, but I don’t want visitors seeing my leg right now” is showing signs of social isolation and low self-esteem.
The client needs emotional support and reassurance from the nurse and family members.
Normal ranges for vital signs after amputation are blood pressure 120/80 mm Hg, pulse 60-100 beats/min, respiratory rate 12-20 breaths/min, and temperature 36.5-37.5°C.
