• In which of the following conditions is a nerve conduction

velocity test MOST appropriate?

• Carpal tunnel syndrome
• Cerebrovascular accident
• Myotonia
• Duchenne muscular dystrophy - ANSWER-A

Nerve conduction velocity testing is most useful in the evaluation of peripheral nerve or lower motor neuron status.Therefore, since carpal tunnel syndrome is the only one of the conditions that directly involves a peripheral nerve; it would be the most appropriate choice. A cerebrovascular accident is an upper motor neuron disorder. Both myotonia and Duchenne muscular dystrophy are primary muscle disorders

• A patient with leukemia has developed thrombocytopenia

following a bone-marrow transplant. Which of the following measures are indicative of the status of the thrombocytopenia?

• T4 lymphocyte count
• Red blood cell count
• Platelet count
• White blood cell count - ANSWER-C

Thrombocytopenia is an acute or chronic decrease in the number of platelets in the circulation. The T4 lymphocyte count is used to assess immune status in patients with HIV or AIDS. The red blood cell count is utilized to assess for presence of anemia and the white blood cell count would be examined to determine presence of infection or degree of immunosuppression

• For a patient with insulin-dependent diabetes who is

completing a cardiovascular fitness program, what change in diabetic management is MOST likely to be instituted as fitness increases?

• Switching to oral rather than injected medication 2 / 4

• Decreasing caloric intake for 2 to 3 hours following exercise

sessions

• Decreasing the amount of insulin taken daily
• Increasing the amount of insulin taken daily - ANSWER-C

Exercise has been shown to increase sensitivity of the insulin receptors therefore leading to a decrease in the amount required.Administration of medication is dictated by tolerance and efficacy of the medication and would not necessarily be altered by exercise. In patients with moderate hyperglycemia, exercise can lead to hypoglycemia for periods of 24 to 48 hours after exercise, therefore increasing caloric intake, particularly carbohydrates, would be essential

• An elderly patient presents with a sacral pressure ulcer

measuring 6 in x 6 in (15 cm x 15 cm). The wound has moderate serous fluid drainage and is loosely covered with necrotic and fibrotic tissue, although there are no indications of infection

present. The BEST method of debridement is:

• daily vigorous scrubbing of the wound.
• wet-to-dry dressings with normal saline 2 times/day. 3 / 4

• | P a g e

C. daily wet-to-dry dressings with 1:1 diluted povidone-iodine

(Betadine).

• whirlpool jet agitation 2 times/day. - ANSWER-B

Wet-to-dry dressings are indicated for necrotic tissue needing debridement. The moderate amount of drainage would require more frequent (i.e., bid) dressing changes. Vigorous scrubbing of the wound could damage friable tissue. Betadine can be cytotoxic. Whirlpool would not be effective in removing necrotic tissue.

• A patient has disuse atrophy of the anterior compartment

muscles following cast removal after a fracture of the tibia. The patient has Poor (2/5) strength in the ankle dorsiflexors.Electrical stimulation is to be used to enhance dorsiflexor strength in conjunction with exercise. Initially, which of the following waveform characteristics are MOST appropriate to stimulate the muscles?

• Monophasic pulse with a frequency of 100 pps and an on/off

cycle ratio of 3:1

• Biphasic pulse with a frequency of 30 pps and an on/off cycle

ratio of 1:5

• Direct current waveform with an on/off ratio of 1:1
