Correct Answer: D

Rationale: The correct answer is D: Dry, brittle hair. Dry, brittle hair is a common sign of malnutrition, often seen in clients with anorexia nervosa. Preoccupation with calories (choice A) is more related to the psychological aspect of anorexia rather than a physical finding. Thick body hair (choice B) is not typically associated with anorexia nervosa. A sore tongue (choice C) can be seen in conditions like vitamin deficiencies or oral health issues but is not specific to anorexia nervosa.

Correct Answer: C

Rationale: When a patient is prescribed an oral anticoagulant, the nurse should monitor for signs of bleeding. Oral anticoagulants work by inhibiting the blood's ability to clot, which increases the risk of bleeding. Monitoring for signs of bleeding such as easy bruising, petechiae, hematuria, or bleeding gums is crucial to prevent complications. Elevated blood glucose (Choice A) is not directly related to oral anticoagulant use. Decreased blood pressure (Choice B) is not a common effect of oral anticoagulants. Increased appetite (Choice D) is not a typical side effect of oral anticoagulants and is not a primary concern when monitoring a patient on this medication.

Correct Answer: C

Rationale: The correct answer is to wear extra warm clothing during cold exposure. This instruction is crucial for managing Raynaud's phenomenon as it helps prevent vasospasms triggered by cold temperatures. Choice A is incorrect because exacerbations can occur in any season. Choice B is not directly related to managing Raynaud's phenomenon. Choice D is also irrelevant as direct sunlight exposure does not typically worsen symptoms of Raynaud's phenomenon.

Correct Answer: B

Rationale: The correct answer is B: 'Spinach and beef.' Spinach and beef are high in iron, which is crucial for treating iron deficiency anemia. Spinach is a good source of non-heme iron, while beef provides heme iron, making them effective choices to increase iron levels in the body. Yogurt and mozzarella (Choice A), fish and cottage cheese (Choice C), and turkey slices and milk (Choice D) do not contain as high iron content as spinach and beef, making them less effective in addressing iron deficiency anemia.

Correct Answer: B

Rationale: The correct action for the nurse to take in this situation is option B: Call the practitioner, report the client's symptoms, and obtain further orders. The client is displaying symptoms that indicate potential complications, such as internal bleeding, which require immediate medical evaluation. Option A is incorrect because the client's condition suggests a more urgent need for assessment. Option C is inappropriate as it does not address the seriousness of the client's symptoms. Option D is dangerous and could exacerbate any underlying issue the client may be experiencing.
