The nurse is reviewing the blood supply to the arm. The major artery supplying the arm is the _____ artery.

Correct Answer: C

Rationale: The correct answer is C: Brachial artery. The brachial artery is the major artery supplying the arm, running from the shoulder to the elbow. It is a continuation of the axillary artery and provides blood to the entire arm. The ulnar and radial arteries are branches of the brachial artery, supplying the forearm and hand. The deep palmar artery is a branch of the radial artery, supplying the palm of the hand. Therefore, the brachial artery is the correct choice as it is the main artery directly supplying the arm.

Correct Answer: B

Rationale: The correct answer is B: Associated manifestations. Associated manifestations refer to other symptoms or signs that accompany the primary symptom. In this case, the primary symptom is abdominal pain, and the description provided focuses solely on the characteristics of the pain itself (location, intensity, duration, aggravating factors), omitting any mention of other symptoms like nausea, vomiting, fever, or jaundice that may be present with certain conditions. By not including information about associated manifestations, the description lacks a complete picture of the symptom presentation, making choice B the correct answer. Choices A, C, and D are incorrect because the description does cover the setting in which the symptom occurs (after eating greasy foods), the quality of the pain (dull ache), and the timing of the pain (2 to 3 hours after eating).

Correct Answer: B

Rationale: The correct answer is B: Hair colour. The rationale for this is that fair skin, family history of melanoma, freckles, and heavy sun exposure are all known risk factors for melanoma. Reddish-blonde hair alone is not a significant risk factor for melanoma compared to the other mentioned factors. Age is a risk factor as melanoma incidence increases with age. Actinic lentigines, also known as sunspots, are associated with chronic sun exposure and are a risk factor for melanoma. Heavy sun exposure is a well-established risk factor for melanoma due to the damaging effects of UV radiation on the skin.

Correct Answer: A

Rationale: The correct answer is A because it covers all essential aspects of the interview contract. Firstly, mentioning confidentiality ensures patient privacy. Secondly, addressing patient costs sets clear expectations. Lastly, explaining the role of each person involved establishes transparency. Choice B is incorrect as it only covers the purpose of the interview and the role of the interviewer, missing important elements like confidentiality and patient costs. Choice C is incorrect as it lacks information on patient costs and the expectations of each person, focusing solely on the time, place, and confidentiality statement. Choice D is incorrect as it only includes the purpose of the interview and a description of the physical examination, missing crucial aspects like confidentiality, patient costs, and roles of individuals involved.

Correct Answer: D

Rationale: The correct answer is D: Right sternocleidomastoid. The sternocleidomastoid muscle is responsible for rotating the head to the opposite side. In this case, with the chin rotated towards the left and ear close to the right shoulder, the right sternocleidomastoid is primarily implicated. The left sternocleidomastoid would cause the opposite head rotation. The cervical paraspinal muscles primarily provide support and stabilization to the spine, not head rotation.
