Physical Examination and Health Assessment 8th Edition Test

Question 1 of 5

Mrs. Anderson presents with an itchy rash which is raised and appears and disappears in various locations. Each lesion lasts for many minutes. What most likely accounts for this rash?

A. Insect bites B. Urticaria, or hives C. Psoriasis D. Purpura

Correct Answer: B

Rationale: Urticaria, commonly known as hives, typically presents as raised, red, and itchy welts or wheals that can appear and disappear in various locations on the skin. Each lesion tends to last for many minutes before resolving and may be associated with itching or a burning sensation. Urticaria is often triggered by an allergic reaction to food, medications, insect bites, or other substances. The clinical presentation described in the question, involving an itchy rash that appears and disappears in different areas, is consistent with urticaria.

Question 2 of 5

A patient is assigned a visual acuity of 20/100 in her left eye. Which of the following is true?

A. She obtains a 20% correct score at 100 feet. B. She can accurately name 20% of the letters at 20 feet. C. She can see at 20 feet what a normal person could see at 100 feet. D. She can see at 100 feet what a normal person could see at 20 feet.

Correct Answer: C

Rationale: In the context of visual acuity, the numbers in the ratio 20/100 represent a comparison between the patient's vision and normal vision. Specifically, a visual acuity of 20/100 means that the patient can see at 20 feet what a person with normal vision can see at 100 feet. This indicates that the patient's vision is reduced, as she needs to be closer to see the same level of detail compared to someone with normal vision.

Question 3 of 5

You are concerned that a patient has an aortic regurgitation murmur. Which is the best position to accentuate the murmur?

A. Upright B. Upright, but leaning forward C. Supine D. Left lateral decubitus

Correct Answer: B

Rationale: Leaning forward in the upright position increases venous return and systemic vascular resistance, which can help accentuate the intensity of aortic regurgitation murmur. This position helps to bring the heart closer to the chest wall, making the murmur easier to auscultate and potentially increasing its intensity.

Question 4 of 5

A 19-year-old construction worker presents for evaluation of a rash. He notes that it started on his back with a multitude of spots and is also on his arms, chest, and neck. It itches a lot. He does sweat more than before because being outdoors is part of his job. On physical examination, you note dark tan patches with a reddish cast that has sharp borders and fine scales, scattered more prominently around the upper back, chest, neck, and upper arms as well as under the arms. Based on this description, what is your most likely diagnosis?

A. Pityriasis rosea B. Tinea versicolor C. Psoriasis D. Atopic eczema

Correct Answer: B

Rationale: The description of dark tan patches with a reddish cast that have sharp borders and fine scales, especially more prominent on the upper back, chest, neck, and upper arms, is classic for tinea versicolor. Tinea versicolor is a superficial fungal infection caused by Malassezia species, which commonly affects individuals who sweat more, such as those working outdoors like the construction worker in this case. The rash is often pruritic (itchy) and can vary in color from tan to pink or red. The fine scales on the patches are a result of the accumulation of the yeast in the affected areas.

Question 5 of 5

You are working in a college health clinic and seeing a young woman with a red, painful, swollen DIP joint on the left index finger. There are also a few papules, pustules, and vesicles on reddened bases, located on the distal extremities. This would be consistent with which of the following?

A. Lyme disease B. Systemic lupus erythematosus C. Hives (urticaria) D. Gonococcal arthritis

Correct Answer: D

Rationale: The description provided indicates a presentation consistent with gonococcal arthritis. Gonococcal arthritis is an infectious arthritis caused by the bacteria Neisseria gonorrhoeae. Symptoms typically include red, swollen, and painful joints, especially affecting the distal joints of the limbs. The presence of papules, pustules, and vesicles on reddened bases at the distal extremities is characteristic of disseminated gonococcal infection. In women, the DIP joint involvement in the finger can be indicative of this condition. Prompt diagnosis and treatment with antibiotics are essential to prevent complications associated with gonococcal arthritis. It is important to consider a sexually transmitted infection like gonorrhea in young patients presenting with joint symptoms and cutaneous findings.
