Correct Answer: A

Rationale: The correct course of action is to encourage warm water soaks to the right foot. This can help promote wound healing and alleviate discomfort. Before recommending increased activity or notifying additional team members, it is crucial to assess arterial blood flow by determining the patient's pulse in the right ankle. Poor arterial blood flow could worsen the condition, making increased activity inappropriate. While notifying the case manager of purulent drainage is important, addressing the wound care directly should be the primary focus at this stage.

Correct Answer: B

Rationale: The facial nerve (VII) is responsible for motor function to the face and sensory function to the anterior two-thirds of the tongue.
Therefore, to appropriately test the function of cranial nerve VII, the most appropriate testing procedures involve assessing the taste sensation over the front of the tongue (sensory) and activation of the facial muscles (motor). Option B, 'Test the taste sensation over the front of the tongue and activation of the facial muscles,' is the correct answer.

Choices A, C, and D are incorrect because they do not involve the correct combination of sensory testing over the front of the tongue and motor activation of the facial muscles, which are key functions associated with cranial nerve VII.

Correct Answer: D

Rationale: Light therapy can be effective in treating problems associated with sleep patterns, stress, moods, jaundice in newborns, and seasonal affective disorders. While light therapy may have other potential benefits, such as improving mood or helping with seasonal affective disorders, the main focus and effectiveness of light therapy are commonly linked to regulating sleep patterns.
Therefore, the correct answer is 'Working with sleep patterns.'

Choices A, B, and C are incorrect as light therapy is not primarily used for overcoming weight problems, helping with allergies, or solely as an alternative medical treatment.

Correct Answer: D

Rationale: The patient's presentation of a warm, red, swollen extremity with a low fever is indicative of cellulitis, which is inflammation of cellular tissue. Cellulitis is commonly associated with these symptoms due to a bacterial infection in the skin and underlying tissues. Herpes (
Choice
A) is a viral infection that typically presents with grouped vesicles, not the warm, red, swollen presentation seen in cellulitis. Scleroderma (
Choice
B) is a chronic autoimmune condition affecting the skin and connective tissue, presenting differently from the acute symptoms of cellulitis. Dermatitis (
Choice
C) refers to skin inflammation, which does not typically present with the described symptoms of warmth, redness, swelling, and low fever observed in cellulitis.

Correct Answer: B

Rationale: Effective Heparin therapy should halt the process of intravascular coagulation, leading to increased availability of fibrinogen. Heparin interferes with thrombin-induced conversion of fibrinogen to fibrin.
Therefore, an increased fibrinogen level indicates a positive response to Heparin therapy. While increased platelet count and decreased bleeding are positive outcomes, the specific indicator for Heparin therapy response is the increase in fibrinogen level. Decreased fibrin split products would also be a positive response, but an increase in fibrinogen directly reflects the impact of Heparin therapy.
